Background technique

Desktop computers are equipped with at least one display device (eg, monitor). Similarly, mobile devices (e.g., mobile phones, smart phones, tablet personal computers (PCs), etc.) with touch screens are also equipped with display devices.

The user may divide the screen of the display device according to the task environment using the desktop computer (for example, the screen is divided horizontally or vertically and a plurality of windows are called in the divided screen). When running a web browser, the user can scroll up or down a web page by means of the page up or down buttons on the keyboard. If the user uses a mouse instead of a keyboard, the user can scroll up or down a web page by selecting a scroll bar in the side of the web page with the mouse cursor. The user can also move to the top of the web page by selecting the top button that appears as text or an icon in the bottom of the web page.

Compared to desktop computers, mobile devices have small screen sizes and are limited in terms of input to the screen. Therefore, it is difficult to divide a screen in a mobile device.

Various applications can be run on the mobile device. Applications include basic applications installed by the manufacturer during manufacturing and additional applications downloaded from application sales sites. Additional applications can be developed by ordinary users and registered to the application sales website. Therefore, anyone is free to sell the applications he or she develops to mobile users through application sales sites. Currently, depending on the product, tens to hundreds of thousands of free or paid applications are available for mobile devices.

Contents of the invention

technical problem

Although mobile devices are provided with many applications that stimulate user interest and meet user needs, mobile devices have limitations in display size and user interface (UI) due to their portable size. As a result, users feel inconvenienced when running multiple applications in their mobile devices. For example, when a user runs an application in a mobile device, the application is displayed throughout the display area. If the user runs another application during the running of the current application, the user needs to first end the ongoing application and then select the run key to run the desired application. For example, a user needs to go through the frustrating process of repeatedly running and terminating each application in order to run multiple applications. However, methods for running multiple applications simultaneously on mobile devices have yet to be specified.

As described above, although mobile devices are provided with many applications that stimulate users' interest and meet user needs, mobile devices have limitations in display size and UI due to their portable size. As a result, users feel inconvenienced when running multiple applications in their mobile devices.

The controller controls display of a window in each of the window display areas 201, 202, 203, and 204 to execute an application in the window. For example, as shown in Fig. 2b, Fig. 2c, Fig. 2d, Fig. 2e, Fig. 2f, Fig. 2g, Fig. 2h, Fig. 2i, Fig. 2j and Fig. 2k, the controller controls the display area 201, 202, 203 and 204 Each of the windows in the display.

The window may include an execution screen of a specific application and a title of the running application. Objects related to the application can be displayed on the running screen of the application. Objects can take many forms, such as text, graphics, icons, buttons, check boxes, photos, videos, web pages, maps, and so on. When the user touches an object, a function or event corresponding to the touched object can be run in the application. Objects may be called views according to the operating system (OS). The title bar may include at least one control key to control the display of the window. For example, the at least one control key may include a window minimize button, a window maximize button, and a window close button.

An application is a program independently written by a manufacturer of the display device 200 or an application developer. Thus, the running of one application does not require the preparatory running of another application. Even when one application ends, another application can continue to run.

Compared to a combined function application (or dual application) designed by adding to one application (for example, a video application) some functions (for example, a note function, a message sending/receiving function, etc.) available in other applications, the applications are independently configuration. Unlike existing applications, a combined function application is a single application configured to include multiple functions. Therefore, the combined function application only provides limited functions like existing applications, and the user will additionally purchase such a new combined function application.

Referring to FIG. 2b , the controller controls the display of the first window 230 to run a startup application: application L in the first window display area 201 . As shown in Figure 2b, launching the application: application L displays the available application icons 231, 232, 233, 234, 235, 236, 237 and 238. When an application execution command is received by a touch on one of the application icons 231 , 232 , 233 , 234 , 235 , 236 , 237 , and 238 , the application is started: application L in the first to fourth display areas 201 , 202 , 203 An application corresponding to the touched icon is displayed in one of 204 and 204 .

3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h and 3i illustrate action stacks managed in a display device according to an embodiment of the present disclosure.

Referring to FIG. 3a, a controller generates and manages a startup application in an action stack in response to execution of the startup application.

Referring to FIG. 2c and FIG. 2d, user 1 may touch an icon 232 representing application B. Referring to FIG. When the icon 232 representing the application B is touched, the controller controls to display the second window 240 in which the application B is executed in the second window display area 202. The controller may display windows in the first to fourth window display areas 201, 202, 203 and 204 in order. For example, the controller may control the display of new windows in the clockwise order of the second window display area 202, the third window display area 203, and the fourth window display area 204. The clockwise window display order is an example of controlling the display of new windows, therefore, the controller may control the display of new windows in counterclockwise order. The order in which new windows are displayed in the window display areas 201, 202, 203, and 204 can be changed.

Fig. 3b shows an action stack corresponding to the window shown in Fig. 2d. The controller generates the application B stack 302 in the action stack in response to the execution of the application B. The controller places the last running application B stack 302 on top of the startup application stack 301. This may imply that application B's Z-order (which may also be described as order, rank, or priority) is higher than the Z-order of the launching application: application L.

Referring to FIG. 2e, user 1 may touch an icon 233 corresponding to application C. Referring to FIG.

Fig. 3c shows an action stack corresponding to the window shown in Fig. 2e. Since User 1 enters an application run command to Launch Application: Application L as shown in Figure 2e, it is noted from Figure 3c that the Z-order of Launch Application Application L is higher than that of Application B.

Referring to FIG. 2f, when the icon 233 representing the application C is touched, the controller controls the display of the third window 250 in which the application C is executed in the fourth window display area 204. Referring to FIG.

Figure 3d shows an action stack corresponding to the window shown in Figure 2f. The controller generates the application C stack 303 in the action stack in response to the execution of the application C. The controller places the last running application C stack 303 on top of the startup application stack 301. This may imply that application C's Z-order is higher than the Z-order of the launching application: application L.

Referring to FIG. 2g, user 1 may touch an icon 234 representing application D. Referring to FIG.

Fig. 3e shows an action stack corresponding to the window shown in Fig. 2g. Since User 1 enters the application run command to Launch Application: Application L as shown in Figure 2g, it is noted from Figure 3e that the Z-Order of Launch Application: Application L is higher than that of Application C.

Referring to FIG. 2h, when the icon 234 representing the application D is touched, the controller controls the display of the fourth window 260 in which the application D is executed in the third window display area 203. Referring to FIG.

Figure 3f shows an action stack corresponding to the window shown in Figure 2h. The controller generates the application D stack 304 in the action stack in response to the execution of the application D. The controller places the last running application D-stack 304 on top of the startup application stack 301 . This may imply that the Z-order of application D is higher than the Z-order of the startup application, application L.

Referring to FIG. 2i , user 1 can operate application B. Referring to FIG.

Fig. 3g shows an action stack corresponding to the window shown in Fig. 2i. The controller places application B stack 302 on top of the action stack in response to user input for application B.

Referring to FIG. 2j , user 1 may touch an icon 235 representing application E. Referring to FIG.

Figure 3h shows the action stack corresponding to Figure 2j. Since User 1 enters the application run command to Launch Application: Application L as shown in Figure 2j, it is noted from Figure 3h that the Z-order of Application L is higher than that of Application D when the application is launched.

When the icon 235 representing the application E is touched, referring to FIG. 2k, the controller controls the display of the fifth window 270 in which the application E is executed in the fourth window display area 204. Referring to FIG. In the absence of an empty window display area, the controller may refer to the action stack shown in Figure 3h. The controller can determine the application with the lowest Z-order in the action stack. For example, the controller may determine that application C's Z-order is the lowest in the action stack of Figure 3h. The controller controls the display of the fifth window 270 in which the application E is executed in the fourth window display area 204 instead of the window of the application C having the lowest Z order.

Fig. 3i shows an action stack corresponding to the window shown in Fig. 2k. The controller generates the application E stack 305 in the action stack in response to the execution of the application E. The controller places the last running application E-stack 305 on top of the startup application stack 301. This may imply that the Z-order of application E is higher than that of the startup application, Application L.

Fig. 4a is a flowchart illustrating a method for controlling a display device according to an embodiment of the present invention.

Referring to FIG. 4a, in operation S401, the display device may execute a plurality of applications. For example, the display device may run an application in response to an application run command triggered by a user touch on an icon representing the application. The display device, and in particular, the display device's window manager, can generate the windows in which the application runs.

A display device may determine a layout for arranging windows. A layout defines the window display area in which windows can be arranged. For example, two modes are available for layout, namely, split mode and freestyle mode.

In split mode, the screen is divided in such a way that multiple windows are displayed without overlapping. For example, if a display device displays a first window and a second window, the display may divide a screen such as a touch screen in a set layout, and define the divided screen portion as a window display area. The display device can display windows in each window display area. Because each window display area is a screen segment, a display device can display multiple windows without overlapping.

A display device can assign multiple windows to one window display area in split mode. For example, the display device may assign the first window and the second window to the first window display area. In this case, the display device may compare the Z-order (order, rank, position in the stack) of the first window and the second window. If the Z-order of the first window is higher than the Z-order of the second window, the display device may display the first window in the first window display area. In this case, although the display device manages the second window to be arranged in the first window display area, the display device does not display the second window in the first window display area.

On the other hand, in Freestyle mode, multiple windows can be displayed overlapping according to their display priority. For example, if a display area of a first window overlaps a display area of a second window, the display device may compare the Z-orders of the first window and the second window. The Z-order of the windows may refer to the display order of the windows. For example, if the Z-order of the first window is higher than the Z-order of the second window, the display device may control to display the first window in the overlapping portion, but not the second window.

In the split mode, various layouts are available, such as 2 top/bottom area split layouts, 2 left/right area split layouts, 3 area split layouts, 4 area split layouts and so on. In operation S405, the display device may determine whether the layout of the windows is in the split mode or the free style mode. If the layout is in split mode, the display device may further determine whether the layout is a 2 top/bottom zone split layout, a 2 left/right zone split layout, a 3 zone split layout, or a 4 zone split layout.

Once the mode of the layout is determined in operation S405, the display device may determine window positions in the layout in operation S407. In the case of 2 upper/lower area layouts, the display device may determine to arrange the first window and the third window in the upper window display area and arrange the second window in the lower window display area. Alternatively, in freestyle mode, the display device may determine a coordinate region for the first window and a coordinate region for the second window.

The display device may determine the Z-order of the plurality of applications in operation S409 and may display the plurality of windows based on the Z-order of the applications in operation S411. For example, in case of 2 upper/lower region split mode, the display device may compare the Z-order of the first window and the third window. In addition, the display device can control the display of windows with relatively higher Z-orders in the corresponding window display area. In freestyle mode, the display device can compare the Z-orders of the first window and the second window and can control the window with the relatively higher Z-order to display in the overlapping region.

Fig. 4b is a flowchart illustrating a method for controlling a display device according to an embodiment of the present invention.

Referring to FIG. 4b, in operation S401, the display device may execute a plurality of applications. For example, an application run command may be triggered by a drag gesture that drags an icon representing the application to a point where a window for the application will be displayed. A drag gesture input is an example of an application run command, so the application can be run in a variety of ways. Those skilled in the art will readily appreciate that the present disclosure is not limited to a particular method of application operation.

In operation S421, the display device may determine whether the current layout is in a freestyle mode. In case of the freestyle mode layout, in operation S423, the display device may determine a Z order of each of the windows in which the plurality of applications are running. In operation S425, the display device may display the windows according to their Z-order.

In case of the split mode layout in operation S421, in operation S431, the display device may arrange windows in the window display area. Also, in operation S433, the display device may determine a Z order of windows in each window display area. For example, the display device may determine the Z-order of the windows as shown in Table 1.

[Table 1]

window Window display area (page) Z order A 1 1 B 2 5 C 3 6 D. 2 2 E. 1 3 f 4 4

As described above, the display device may control to display window A having a relatively higher Z-order instead of window E in the first window display area. The display device may control to display window D having a relatively higher Z-order instead of window B in the second window display area. Also, the display device may display window C in the third window display area and display window F in the fourth window display area. For example, in operation S435, the display device may display, in each window display area, a window having the highest Z-order among windows allocated to the window display area.

FIG. 5 illustrates a display order (Z order) of windows according to an embodiment of the present disclosure.

Referring to FIG. 5 , the Z order of the screen may be divided into N layers, and the Nth layer may be an upper layer placed on the (N-1)th layer. Windows can exist in each layer and applications can run in windows. For example, when running the first application, the first application runs in a window of the first layer. When the second application is run, the second application runs in a window of the second layer, and when the third application is run, the third application runs in a window of the third layer. Therefore, the first layer, the second layer and the third layer are created hierarchically. The layer created last can be the top of the layer stack and, therefore, can be displayed on top of the screen. For example, a plurality of windows (a) to (d) may be overlapped and displayed on the main screen. For example, the first window (a) overlaps the second window (b), the third window (c) and the fourth window (d), and the second window (b) overlaps the third window (c) and the fourth window (d). Four windows (d) are displayed on top, and the third window (c) is displayed overlapping on the fourth window (d). For example, when a plurality of windows (a) to (d) are overlapped and displayed, the order in which the windows (a) to (d) are displayed is the Z order of the windows (a) to (d). The Z-order may be the order in which the windows are displayed along the Z-axis. A layer view (e) may be a screen that displays a Z-order of windows hierarchically. The Z-order may be referred to as a display order.

Fig. 6a, Fig. 6b, Fig. 6c and Fig. 6d illustrate an application running method according to an embodiment of the present disclosure. More specifically, Figures 6a, 6b, 6c and 6d illustrate methods for running an application in a freestyle mode layout.

Referring to FIGS. 6a , 6b , 6c and 6d , the display device 600 displays a window display area 620 . The display device 600 displays a tray 610 accommodating available application icons 611 , 612 , 613 , 614 , 615 , 616 , and 617 to the left of the window display area 620 . The user 10 may operate the display device 600 to execute the first application A1. For example, in FIG. 6 b , the user 10 may make a drag gesture 625 of dragging the icon 611 representing the first application A1 to the first point in the window display area 620 . The display device 600 may display a first window 630 at a first point in the window display area 620 in response to the drag gesture 625 to execute the first application A1 in the first window 630. The first window 630 may be displayed in a default size and shape or in a size and shape set by the user 10 before being terminated.

The user 10 may operate the display device 600 to additionally execute the third application A3. For example, the user 10 may make a drag gesture 635 of dragging the icon 613 representing the third application A3 to the second point in the window display area 620, as shown in FIG. 6c. The display device 600 may display the third window 640 at the second point in the window display area 620 in response to the input execution command (i.e., the drag gesture 635) to execute the third application A3 in the third window 640. The third window 640 may be displayed in a default size and shape or in a size and shape set by the user 10 before being terminated. Since the third window 640 is the last window to which the user 10 has applied a gesture input, the controller (not shown) may assign a higher task priority level to the third application A3 than the first application A1. Accordingly, the controller may control the third application A3 to be displayed on the first application A1.

FIG. 7 is a flowchart illustrating a method for controlling a display device according to an embodiment of the present invention.

Referring to FIG. 7, in operation S701, the display device may display at least one icon representing an application. For example, the display device may display a tray accommodating at least one icon in a portion of the touch screen.

In operation S703, when the user drags the icon to the first point where the window is to be arranged, the display device may receive a drag gesture input. The display device may recognize a drag gesture from the icon to the first point as a command to execute an application corresponding to the icon. More specifically, in operation S705, the display device may determine the position of the first point on the layout where the drag gesture has ended. For example, if the split mode has been set for layout, the display device can determine the window area corresponding to the first point on the layout.

In operation S707, the display device may determine at least one of the size and position of the window according to the position of the first point on the layout. In operation S709, the display device may display the window according to the determined size and/or position.

8a, 8b, 8c, 8d, 8e, 8f, 8g, 8h, 8i, 8j, 8k, 8l, and 8m illustrate a method for displaying multiple method of a window.

8a, 8b, 8c, 8d, 8e, 8f, 8g, 8h, 8i, 8j, 8k, 8l, and 8m, the display device 800 displays a menu screen 817. The menu screen 817 may be an execution screen of a startup program and may include icons representing applications. In addition, the menu screen 817 may include information about the current time and may further include widgets. The display device 800 displays a tray 810 accommodating available icons 811, 812, 813, 814, 815, and 816 to the left of the touch screen.

As shown in FIG. 8b, the user 10 may operate the display device 800 to run the first application A. As shown in FIG. For example, the user 10 may touch the icon 811 representing the first application A and drag the touched icon 811 to the menu screen 817, as shown in FIG. 8c. A controller (not shown) may control the display of the icon 811 at the drag point. The controller may further control the display of a ghostview 818 at the drag point. The ghost view 818 refers to a preview of the size and shape of the window in which the first application A will run, so that the user 10 can select a window location. The controller may display the ghost view 818 full screen because no windows are already displayed. As described below, the controller can control the display of the full screen ghosted view in the absence of any windows already displayed on the touch screen. If a single window is already displayed on the touch screen, the controller may display the double view in a size and shape corresponding to half of the touch screen. If two windows are already displayed on the touch screen, the controller may display a double view with a size and shape corresponding to half of one of the two windows on the touch screen. If three windows have been displayed on the touch screen, the controller may display a double view in a size and shape corresponding to half of the largest one of the three windows.

The controller may recognize the above-mentioned drag gesture as a command for running a new application. The controller may generate a first window 819 for executing the first application A. As shown in FIG. 8d, the controller may control the display of the first window 819 in full screen.

The user 10 may operate the display device 800 to additionally execute the second application B. FIG. For example, as shown in FIG. 8e, the user may touch the icon 812 representing the second application B, and drag the touched icon 812 toward the lower half of the first window 819 as shown in FIG. 8f. The controller may control the display of the icon 812 at the dragged point. Also, the controller may control the display of the double view view 823 at the drag point. As previously described, since the single window 819 has been displayed on the touch screen, the controller may control the ghost view 823 to be displayed in a size and shape corresponding to half of the touch screen. Although not shown, if the user 10 drags the touched icon 812 toward the upper half of the touch screen, the controller controls the display of the ghost image 823 at the upper half of the touch screen. Displaying a double view on the lower half of the touch screen is just an example of displaying a double view, therefore, the controller can divide the touch screen into a left half and a right half and can control the left half and the right half of the touch screen Show the double view in one of the .

If the user finishes dragging in the lower half of the touch screen as shown in FIG. 8f, the controller determines that a new application execution command has been received. As shown in FIG. 8g, consistent with the double view view 823 shown in FIG. 8f, the controller controls to display a second window 830 in the lower half of the touch screen. In addition, the controller reduces the size and shape of the first window 819 to the first window 820 so that the first window 820 can be displayed in the upper half of the touch screen. The controller generates and displays a center button 825 at the border between the first window 820 and the second window 830 .

The user 10 may operate the display device 800 to additionally execute the third application C. FIG. For example, as shown in FIG. 8h, the user may touch the icon 813 representing the third application C, and drag the touched icon 813 to the right of the first window 820 as shown in FIG. 8i. The controller can control the icon 813 to be displayed at the dragged point. In addition, the controller may control the double view view 827 to be displayed at the dragged point. As previously described, since the two windows 820 and 830 have been displayed on the touch screen, the controller may control the display of the ghost view 827 in a size and shape corresponding to half of the first window 820. Although not shown, if the user 10 drags the touched icon 813 toward the left of the first window 820 , the controller controls to display a double view view 827 in the left half of the first screen 820 . Displaying the double view 827 on the right half of the first window 820 is only an example of displaying the double view, therefore, the controller can divide the first window 820 into an upper half and a lower half and can control the double view on the first screen. A ghost view 827 is displayed in one of the upper and lower halves of 820 . Displaying a ghost view 827 in half of the first window 820 is another example of displaying a ghost view. The controller may determine the size and shape of the ghost view 827 relative to the center button 825 and display the ghost view 827 accordingly.

If the user finishes dragging in the right part of the first window 820 as shown in FIG. 8i, the controller determines that a new application execution command has been received. As shown in FIG. 8j , the controller controls to display a third window 840 in the right half of the first screen 820 , consistent with the double view 827 shown in FIG. 8i . Alternatively, in line with the position of the center button 825, the controller may control the third window 840 to be displayed. Thus, as more applications are selected to run, portions of the screen may gradually be subdivided to assign each running application a respective portion of the screen.

In addition, the controller reduces the size and shape of the first window 820 in line with the creation of the third window 840. For example, the controller may control the first window 820 to be displayed in an area other than the display area of the third window 840 .

The user 10 may operate the display device 800 to additionally execute the fourth application D. FIG. For example, as shown in FIG. 8k, the user may touch the icon 814 representing the fourth application D, and as shown in FIG. 81, drag the touched icon 814 to the right of the second window 830. The controller can control the icon 814 to be displayed at the dragged point. In addition, the controller may control the double view view 831 to be displayed at the dragged point. As previously described, since the three windows 820, 830, and 840 have been displayed on the touch screen, the controller can control the display of the ghost view 831 in a size and shape corresponding to half of the second window 830. Although not shown, if the user 10 drags the touched icon 814 toward the left of the second window 830, the controller controls the display of the double view view 831 in the left half of the second screen 830. Displaying the double view 831 on the right half of the second window is just an example of displaying the double view, therefore, the controller can divide the second window 830 into an upper half and a lower half and can control the display on the second screen 830. A double view view 831 is displayed in one of the upper and lower halves of . Displaying a ghost view 831 in half of the second window 830 is another example of displaying a ghost view. The controller may determine the size and shape of the ghost view 831 relative to the center button 825 and display the ghost view 831 accordingly.

If the user finishes dragging in the right part of the second window 830 as shown in FIG. 81, the controller determines that a new application execution command has been received. As shown in FIG. 8j, the controller controls to display a fourth window 850 in the right half of the second screen 830, consistent with the double view view 831 shown in FIG. 8l. Alternatively, in line with the position of the center button 825, the controller may control the fourth window 850 to be displayed.

In addition, the controller reduces the size and shape of the second window 830 in line with the creation of the fourth window 850.

As described above, the display device may control the window to be displayed in the window display area where the drag gesture ends. In Fig. 8a, Fig. 8b, Fig. 8c, Fig. 8d, Fig. 8e, Fig. 8f, Fig. 8g, Fig. 8h, Fig. 8i, Fig. 8j, Fig. 8k, Fig. 8l and Fig. 8m, the windows are displayed at different positions with the same size. Referring to Figure 9a, Figure 9b, Figure 9c, Figure 9d, Figure 9e, Figure 9f, Figure 9g, Figure 9h, Figure 10a, Figure 10b, Figure 10c, Figure 10d, Figure 11a, Figure 11b, Figure 11c, Figure 12a, Figure 12b, 12c, 13a, 13b, 13c, 14a, 14b, 14c, 15a, 15b, 15c, 16a, 16b, 16c, 16d and 17, will be in the following Various embodiments are described in which windows are configured in different sizes at different locations.

Figures 9a, 9b, 9c, 9d, 9e, 9f, 9g and 9h illustrate layouts according to embodiments of the disclosure.

Fig. 9a shows a full screen layout for the case where no split mode is set. In Fig. 9a, the display device defines a first window display area 901 throughout the entire screen.

FIG. 9 b shows an input area 902 corresponding to the first window display area 901 .

Figure 9c shows the screen layout in 2 up/down area split mode. In FIG. 9c, the display device may divide the screen into an upper area and a lower area and define a first window display area 911 and a second window display area 912 in the upper area and the lower area, respectively.

Figure 9d shows the input area in 2 upper/lower area split mode. The first input area 913 may correspond to the first window display area 911 and the third input area 915 may correspond to the second window display area 912. The second input area 914 may correspond to a boundary between the first window display area 911 and the second window display area 912. For example, when the user makes a drag gesture of dragging an icon toward the first input area 913, the display device may display a window in the first window display area 911 shown in FIG. 9c. For example, when the user drags an icon to the third input area 915, the display device may display a window in the second window display area 912 shown in FIG. 9c. For example, when a user drags an icon to the second input area 912, the display device may display windows throughout the entirety of the first window display area 911 and the second window display area 912 shown in FIG. 9c.

Figure 9e shows the screen layout in 2 left/right area split mode. In FIG. 9e, the display device may divide the screen into left and right regions and define a first window display region 921 and a second window display region 922 in the left and right regions, respectively.

Figure 9f shows the input area in 2 left/right area split mode. The first input area 923 may correspond to the first window display area 921 and the third input area 925 may correspond to the second window display area 922.

FIG. 35 is a flowchart illustrating a method for controlling a display device according to an embodiment of the present invention.

Referring to FIG. 35 , the controller may set a layout in a freestyle mode in operation S3501. The controller may receive an application execution command, and thus, a plurality of windows for executing a plurality of applications may be generated in operation S3503. The controller may determine a Z order of each of the plurality of windows in operation S3505 and may display the windows based on their Z order in operation S3507.

In operation S3509, the controller may determine whether a Z-order change command has been received. When the Z order change command is received, the controller may control overlapping windows to be displayed according to the changed Z order in operation S3511.

36a, 36b, and 36c show screens of a display device describing a Z-order change command according to an embodiment of the present disclosure and FIGS. 37a, 37b, and 37c show action stacks according to an embodiment of the present disclosure.

Referring to FIGS. 36a, 36b, 36c, 37a, 37b, and 37c, the controller may manage the action stack shown in FIG. 37a. For example, the controller may assign the lowest Z-rank to window A running application A, the middle Z-rank to window B running application B, and the highest Z-rank to window C running application C. Accordingly, the controller may display windows in the order of window C 3631 and 3632, window B 3621 and 3622, and window A 3611 and 3612, as shown in FIG. 36a.

User 1 can input a Z-order change command. When the title bar 3631 is touched in window C as indicated by reference numeral 3641, the Z-order change command may be triggered by a pinch-out gesture 3642 to the left. A pinch can be a gesture that spreads two touch points. In this case, the Z-order of windows C 3631 and 3632 can be reset to the lowest Z-order. As a result, the controller assigns window A the middle Z-order, window B the highest Z-order, and window C the lowest Z-order. For example, the controller may assign window C the lowest Z-order while increasing the Z-orders of other windows by one. Accordingly, the controller may control the windows to be displayed in the order of windows B 3621 and 3622, windows A 3611 and 3612, and windows C 3631 and 3632. A pinch is a Z-order change command, and therefore, those skilled in the art readily understand that the Z-order change command can be triggered by various gestures including flick, drag, edge flick, touch and tilt, tilt, and shake.

User 1 can input a Z-order change command. When the application running screen 3622 is touched in window B as indicated by reference numeral 3651, the Z order change command can be triggered by a pinch gesture 3652 to the left. In this case, the Z-order of windows B 3621 and 3622 may be reset to the lowest Z-order. As a result, the controller assigns the highest Z-rank to window A, the lowest Z-rank to window B running application B, and the middle Z-rank to window C running application C. For example, the controller may assign window B the lowest Z-order while increasing the Z-orders of other windows by one. Accordingly, the controller may control the windows to be displayed in the order of window A 3611 and 3612 , window C 3631 and 3632 , and window B 3621 and 3622 .

38a, 38b, and 38c show screens of a display device describing a Z-order change command according to an embodiment of the present disclosure and FIGS. 39a, 39b, and 39c show action stacks according to an embodiment of the present disclosure.

Referring to FIGS. 38a, 38b, 38c, 39a, 39b, and 39c, the controller may manage the action stack shown in FIG. 39a. For example, the controller may assign the lowest Z-rank to window A running application A, the middle Z-rank to window B running application B, and the highest Z-rank to window C running application C. Accordingly, the controller may display windows in the order of window C 3631 and 3632, window B 3621 and 3622, and window A 3611 and 3612, as shown in FIG. 38a.

User 1 can input a Z-order change command. When the title bar 3631 is touched in window C as indicated by reference numeral 3841, the Z-order change command can be triggered by a pinch-in gesture 3842 from the left. A pinch can be a gesture that narrows the distance between two touch points. In this case, the Z-orders of windows A 3631 and 3632 with the lowest Z-orders may be reset to the highest Z-orders, while lowering the Z-orders of the other windows by one. Thus, the controller may assign the highest Z-order to window A, the lowest Z-order to window B running application B, and the middle Z-order to window C running application C, as shown in Figure 39b.

As shown in FIG. 38b, the controller may control the windows to be displayed in the order of window A 3611 and 3612, window C 3631 and 3632, and window B 3621 and 3622. User 1 may input a Z order change command. When a title bar 3631 is touched in window C as indicated by reference numeral 3851, a Z-order change command may be triggered by a pinch gesture 3852 from the left. In this case, the Z-orders of windows B 3621 and 3622 with the lowest Z-orders may be reset to the highest Z-orders while reducing the Z-orders of other windows by one. As a result, the controller can assign the middle Z-order to window A running application A, the highest Z-order to window B running application B, and the lowest Z-order to window C running application C, as shown in Figure 39c.

Accordingly, the controller may control the windows to be displayed in the order of windows B 3621 and 3622, windows A 3611 and 3612, and windows C 3631 and 3632.

As described above, when receiving a Z order change command through a pinch gesture, the controller may assign the lowest Z order to a window having the highest Z order. Conversely, when receiving a Z-order change command through a pinch gesture, the controller may assign the highest Z-order to a window having the lowest Z-order. Since the user can change the Z order of windows by simple manipulation, desired windows appear on top of the screen. Therefore, user convenience can be improved.

40a, 40b, 40c, 40d, 40e, 40f, 40g, 40h, 40i, 40j, and 40k illustrate a method for displaying an application execution window according to an embodiment of the present disclosure.

For the convenience of describing FIG. 40a and subsequent drawings, the plurality of areas 4201, 4202, 4203, and 4204 are respectively referred to as the first area 4201, the second area 4202, the third area 4203, and the fourth area 4204 (area 1, Region 2, Region 3 and Region 4). Both the first region 4201 and the third region 4203 form a fifth region (region 5, not shown) and both the second region 4202 and the fourth region 4204 form a sixth region (region 6, not shown). Both the first region 4201 and the second region 4202 form a seventh region (region 7, not shown) and both the third region 4203 and the fourth region 4204 form an eighth region (region 8, not shown). The first to fourth regions 4201, 4202, 4203, and 4204 form a region F. The first boundary 4211 can be set between the first area 4201 and the second area 4202, the second boundary 4212 can be set between the third area 4203 and the fourth area 4204, and the third boundary 4213 can be set between the first area 4201 and the second area 4202. Between the third area 4203 , and a fourth boundary 4214 may be provided between the second area 4202 and the fourth area 4204 . The first boundary 4211 and the second boundary 4212 may form a single line, and the third boundary 4213 and the fourth boundary 4214 may form a single line. The first to fourth boundaries 4211 to 4214 are not necessarily displayed explicitly. Instead, the first to fourth boundaries 4211 to 4214 may be dashed lines. A controller (not shown) may configure the first to fourth areas 4201, 4202, 4203, and 4204 in such a manner that the first to fourth areas 4201, 4202, 4203, and 4204 do not overlap. For example, as shown in FIG. 40a, the controller may configure a first area 4201 in the upper left corner, a second area 4202 in the upper right corner, a third area 4203 in the lower left corner, and a fourth area 4204 in the lower right corner. The controller may divide the screen into left and right parts by a first boundary 4211 and a second boundary 4212, and divide the screen into upper and lower parts by a third boundary 4213 and a fourth boundary 4214.

The touch screen may display a center button 4220 at an intersection where the first to fourth boundaries 4211 to 4214 meet. The center button 4220 may be a function key to change the size of an area in which the application execution window is displayed or to set an operation mode for controlling the execution window.

The controller may control the touch screen in such a manner that the application execution window is displayed in each of the plurality of areas. For example, the controller may control the touch screen so that a window for running an application is displayed, that is, the application running window is displayed in each of areas 4201, 4202, 4203, and 4204, as shown in FIGS. 40b, 40c, 40d, 40e, and 40f. , Figure 40g, Figure 40h, Figure 40i, Figure 40j and are shown in.

Objects related to the application may be displayed on the running screen of the application. Objects can take many forms, such as text, graphics, icons, buttons, check boxes, photos, videos, web pages, maps, and more. When a user touches an object, a function or event corresponding to the touched object may run in the application. Objects can be called views according to the OS. For example, at least one of a capture button that captures the running window to control the display of the running window, a minimize button that minimizes the size of the running window, a maximize button that maximizes the size of the running window, and an exit button that ends the running window may be displayed .

Referring to FIG. 40b, the controller may control icons 4231, 4232, 4233, 4234, 4235, 4236, and 4237 representing executable applications to be displayed on the touch screen. Display device 4200 may run application A. As shown in FIG. 40b, in response to the execution of application A, the controller may control the touch screen to display an execution window 4230 of application A in the first area 4201. In addition, the controller may control icons 4231, 4232, 4233, 4234, 4235, 4236, and 4237 representing executable applications to be displayed at specific positions of the touch screen. When receiving a touch input to one of the icons 4231, 4232, 4233, 4234, 4235, 4236, and 4237, that is, when receiving an input to select an icon representing an application to be executed, the display device 4200 may be in the first to second positions. An execution window of an application corresponding to the selected icon is displayed in one of four areas 4201, 4202, 4203, and 4204.

The controller may display an indicator 4221 indicating an active area on the displayed center button 4220 . The active area may be an area in which the last executed application or the last application selected by the user is displayed. An application operated by a user may be considered a user-selected application.

The indicator 4221 can be implemented in various ways to indicate the location of the active zone. For example, at least a part of the application execution window displayed in the active area may be displayed in an overlapping area between the application execution window of the active area and the center button 4220. Alternatively, an arrow indicating the direction of the active area may be displayed on the center button 4220.

The active area can be determined based on the action stack. The last running application or the last user selected application may be at the top of the action stack. The display device 4200 may determine an area in which the execution window of the application on top of the action stack is displayed as the active area. The active area may be referred to as a focal area. For example, in FIG. 40b, the indicator 4221 may indicate the first area 4201.
