The realization of the present invention is described in detail below in conjunction with specific embodiment:

Embodiment one

Fig. 1 shows the implementation process of the screen content sharing method provided by Embodiment 1 of the present invention, which is described in detail as follows:

In step S101, when the mobile terminal shares screen content with the terminal device, the mobile terminal monitors the type of the currently running application.

In the embodiment of the present invention, when the mobile terminal and the terminal device share the screen content, the wfd application is started, and the wfd application is an application for realizing the screen content sharing between the mobile terminal and the terminal device. The mobile terminal is installed with a wfd application, and after starting the wfd application, the content on the screen of the mobile terminal can be shared to the screen of the terminal device.

The type of the currently running application can be monitored in real time through the wfd application. The process name corresponding to the application contains keywords matching the type of the application, and the mobile terminal searches for the process names of all currently running processes. If these process names contain keywords matching the type of the preset application, then Indicates that the corresponding type of application is running.

Specifically, after starting an application, the mobile terminal system will automatically create a process corresponding to the application, that is, each started application is associated with a uniquely identified process name.

For each type of application, the corresponding process name includes different keywords. For example, the process names corresponding to music playing and video playing applications respectively contain keywords "music" and "video" matching the types of the applications.

Therefore, the type of the currently running application can be determined by searching whether the process names of all currently running processes contain a keyword matching the type of the application. If found, it means that the corresponding type of application is running. For example, if the process name of all currently running processes contains "music", it means that the currently running application is a music playback application; if the process name of all currently running processes contains "video", it means The currently running application is a video playback application.

Specifically, you can use the following command to search for processes that match the application: ps|grep "video"

Among them, ps means to view all currently running processes, and grep "video" means to search for the keyword "video" in the process names of all currently running processes, if the keyword "video" is found in the process name of the current process , it means that the currently running application is a video playback application.

Wherein, the mobile terminal in the embodiment of the present invention refers to a mobile phone or a mobile PC, and the terminal device refers to a TV or a monitor.

In step S102, when the mobile terminal detects that the type of the currently running application matches the type of the preset application, the screen is turned off. The preset application is when the mobile terminal shares the screen content with the terminal device and does not An application that brightens the screen of a mobile terminal.

In the embodiment of the present invention, the preset applications are video playback and music playback applications that do not require the mobile terminal to turn on the screen when the mobile terminal shares screen content with the terminal device.

When the mobile terminal detects that the currently running application is an application such as a video playback type or a music playback type that does not require the screen of the mobile terminal to be turned on, the screen is turned off.

In this embodiment, when the mobile terminal shares the screen content with the terminal device, when the mobile terminal monitors that the currently running application is an application that does not require the mobile terminal to turn on the screen, such as playing video or music , automatically turn off the screen, can reduce the current consumption of the mobile terminal, prolong the use time of the mobile terminal, and improve the user experience.

Embodiment two

FIG. 2 shows the implementation process of the screen content sharing method provided by Embodiment 2 of the present invention, which is described in detail as follows:

In step S201, when the mobile terminal shares screen content with the terminal device, the mobile terminal monitors the type of the currently running application.

In the embodiment of the present invention, because some users may really need to light up the mobile terminal screen all the time, an optional menu of "automatically turn off LCD brightness" is added to the wfd application for users to choose. Users can turn on the "automatically turn off LCD "Brightness" function, and then when it is detected that the type of the currently running application matches the type of the preset application, step S201 and S202 are executed in sequence to use the screen-off function to turn off the screen of the mobile terminal. If the user really needs to light up the screen of the mobile terminal all the time, the function of "automatically turning off LCD brightness" is turned off, and steps S201, S202 and S203 are not executed. Of course, it can be set to enable this function by default.

In step S202, when the mobile terminal detects that the type of the currently running application matches the type of the preset application, the screen is turned off. The preset application is when the mobile terminal shares the screen content with the terminal device and does not An application that brightens the screen of a mobile terminal.

In the embodiment of the present invention, after the user turns on the "automatically turn off LCD brightness" function, the mobile terminal monitors the type of the currently running application, and when the mobile terminal detects that the currently running application is sharing screen content between the mobile terminal and the terminal device, When an application that does not require the mobile terminal to turn on the screen, the mobile terminal screen can be turned off.

Preferably, in order to avoid an abrupt feeling to the user by turning off the screen immediately after running the application, and to further improve the user experience, the mobile terminal monitors that the currently running application is sharing the screen content with the terminal device, and does not need the mobile terminal When the screen is turned on, a timer is started, and the timer is used to monitor whether the timing time reaches the preset timing time, and if so, the screen is turned off.

Specifically, when the mobile terminal detects that the currently running application is sharing the screen content between the mobile terminal and the terminal device, it first starts a timer, and the timing time can be preset, such as 60s. When the timer detects that the timing time reaches 60s , activate the function of "automatically turn off LCD brightness" and turn off the screen.

Specifically, the screen-off operation is realized by controlling the brightness of the LCD of the mobile terminal. The control of the LCD brightness of the mobile terminal can be realized by writing a file. Among them, the command to control the brightness of the LCD is stored as a node in the file, and the command to control the brightness of the LCD is as follows:

echo 0>/sys/class/leds/lcd-backlight/brightness Turn off LCD brightness and turn off the screen

The range of LCD brightness is 0~255, 255 means the maximum brightness, the screen is the brightest, 0 means the minimum brightness, the screen is off, there is a default LCD brightness when the mobile terminal is turned on, usually 102, users sometimes adjust the LCD brightness according to the environment , so that the LCD brightness will change correspondingly, the larger the LCD brightness value, the brighter the screen.

By writing any integer brightness value within the range of 0 to 255 into the file, the LCD brightness required by the user can be achieved.

The current LCD brightness can be obtained through the above command, and at the same time turn off the LCD brightness to turn off the screen of the mobile terminal, which will generally reduce the current of about 100-200mA. Note that this is just to turn off the LCD brightness. The wfd application does not allow the mobile terminal to stand by, because The mobile terminal needs to send data to the terminal device in real time.

Preferably, after step S202, step S203 is further included.

In step S203, the mobile terminal lights up the screen according to the received screen brightening instruction.

Specifically, the user can press the power button to input a bright screen command to the mobile terminal. When the mobile terminal detects that the user presses the power button to turn on the screen, the LCD brightness can be restored to the LCD brightness before the screen was turned off, or the LCD brightness can be set to The brightness value you need.

Wherein, the user can light up the screen of the mobile terminal by pressing the power button at any time after the screen is turned off.

Specifically, execute the following command to light up the screen to the required LCD brightness:

echo X>/sys/class/leds/lcd-backlight/brightness

Wherein, X is the LCD brightness value after the screen is turned on, and the brightness value may be the LCD brightness value randomly assigned by the mobile terminal, or the LCD brightness value stored by the mobile terminal before the screen is turned off.

Among them, before the screen is turned off, the LCD brightness value can be obtained through the following command:

cat/sys/class/leds/lcd-backlight/brightness assumes that the return value is X, and X represents the current LCD brightness of the mobile terminal

The value returned by this command is the LCD brightness value, which is stored. When the screen needs to be turned on, the mobile terminal can set the LCD brightness value to this brightness value, and then restore the LCD brightness to the LCD brightness value before the screen was turned off.

In this embodiment, when the screen is turned off, the screen can be turned on at any time according to the needs of the user, so as to improve the user experience. In addition, when it is detected that the currently running application is an application that does not need to turn on the screen, the screen can be turned off after the predetermined time is reached, so as to avoid the sudden feeling of the user caused by the too fast turn-off of the screen. In addition, according to the needs of the user, the function of turning on the screen and turning off the screen can be selected, which can be applied to different users and provide different user experiences for different users.
