The electronic device has an adjacent first touch screen and a second touch screen. The electronic device is preferably a mobile phone. However, in various embodiments, the electronic device can also be a mobile network device, a personal digital assistant, an e-book, a digital photo frame, a digital walkman, an electronic dictionary, a global positioning system navigation machine, and the like. A device with a dual touch screen.

如圖1A及圖1B之立體圖所示,本發明之雙螢幕顯示裝置800包含樞接軸300、第一觸控螢幕100、第二觸控螢幕200以及控制器400。第一觸控螢幕100,第二觸控螢幕200均樞接於樞接軸300,而可相對於樞接軸300轉動。As shown in the perspective view of FIG. 1A and FIG. 1B, the dual screen display device 800 of the present invention includes a pivot axis 300, a first touch screen 100, a second touch screen 200, and a controller 400. The first touch screen 100 and the second touch screen 200 are both pivotally connected to the pivot shaft 300 and rotatable relative to the pivot shaft 300.

如圖2A及圖2B所示,第二觸控螢幕200可相對於第一觸控螢幕100轉動,並可自第一相對位置701移動至第二相對位置702。具體而言,如圖1A及圖1B之立體圖,當第二觸控螢幕200位於第一相對位置701,第一觸控螢幕100及第二觸控螢幕200為相對展開狀態,當第二觸控螢幕200位於第二相對位置702,第一觸控螢幕100及第二觸控螢幕200係為相背對之疊合狀態。As shown in FIG. 2A and FIG. 2B , the second touch screen 200 is rotatable relative to the first touch screen 100 and is movable from the first relative position 701 to the second relative position 702 . Specifically, as shown in FIG. 1A and FIG. 1B, when the second touch screen 200 is located at the first relative position 701, the first touch screen 100 and the second touch screen 200 are in a relative unfolded state, and the second touch The screen 200 is located at the second relative position 702, and the first touch screen 100 and the second touch screen 200 are in a superposed state.

如圖3所示,使用者使用本發明所描述的可摺疊雙螢幕行動電話進行通話時,預期(1)使用者應該會將雙螢幕行動電話加以摺疊而成相背對之疊合狀態,以便單手握持該行動電話;且(2)使用者之臉頰應該會貼近該行動電話裝設有聽筒與麥克風相同側之第一觸控螢幕100,而把沒有聽筒與麥克風的相對側摺到相背對面,亦即第二觸控螢幕200會被折到背面。As shown in FIG. 3, when a user makes a call using the foldable dual-screen mobile phone described in the present invention, it is expected that (1) the user should fold the dual-screen mobile phone into a folded-up state so that Holding the mobile phone with one hand; and (2) the user's cheek should be close to the first touch screen 100 on the same side of the mobile phone with the handset and the microphone, and the opposite side of the handset and the microphone are folded Back to face, that is, the second touch screen 200 will be folded to the back.

在此預期的使用狀態中,使用者手持電子裝置800進行通話時,臉頰係貼觸於電子裝置之第一觸控螢幕100。其中,可以設定一般使用者使用手指或觸控筆操作觸控螢幕時,在觸控螢幕所可能產生之最大面積為第一面積。In the intended use state, when the user holds the electronic device 800 to make a call, the cheek is attached to the first touch screen 100 of the electronic device. The maximum area that can be generated on the touch screen when the general user uses the finger or the stylus to operate the touch screen is the first area.

當第一螢幕100被觸碰之面積大於上述第一面積,則電子裝置800判定目前是使用者臉頰接觸到第一螢幕100;因此可如圖4之步驟1910關閉第一觸控螢幕之觸控功能電路,藉以避免通話時因使用者臉頰接觸第一觸控螢幕100而誤動作啟動其他操作。另一方面,若使用者持用電子裝置800進行通話時臉頰未貼觸於電子裝置之第一觸控螢幕100,第一觸控螢幕之觸控功能電路則不會關閉。When the area touched by the first screen 100 is greater than the first area, the electronic device 800 determines that the user's cheek is touching the first screen 100; therefore, the touch of the first touch screen can be turned off as shown in step 1910 of FIG. The function circuit can be used to avoid other actions caused by the user's cheek contacting the first touch screen 100 during a call. On the other hand, if the user does not touch the first touch screen 100 of the electronic device while the user is holding the electronic device 800, the touch function circuit of the first touch screen will not be closed.

如圖4所示,係本發明雙螢幕顯示裝置進入省電模式之第一實施例流程,控制雙螢幕顯示裝置如何進入省電模式:As shown in FIG. 4, the flow of the first embodiment of the dual screen display device of the present invention enters the power saving mode, and controls how the dual screen display device enters the power saving mode:

步驟1100:電子裝置接受他方的來電訊號。Step 1100: The electronic device accepts the incoming call signal of the other party.

步驟1350:電子裝置偵測使用者是否要接聽該通電話,如偵測使用者是否:(1)觸控第一觸控螢幕上特定區塊,代表通話鍵之圖標(icon);或(2)按壓電子裝置於觸控螢幕外所設置的通話鍵等方式。Step 1350: The electronic device detects whether the user wants to answer the call, such as detecting whether the user: (1) touching a specific block on the first touch screen, representing an icon of the call button; or (2) Pressing the call button set by the electronic device outside the touch screen.

步驟1400:電子裝置因應使用者輸入而啟動通話功能。Step 1400: The electronic device activates the call function according to the user input.

步驟1600:判斷電子裝置是否啟動免持聽筒功能。當電子裝置啟動免持聽筒功能時,電子裝置只需要判斷於應答時間內是否接收到使用者說話之語音訊號,而會略過稍後的第一觸控螢幕觸碰面積大小判斷步驟1710。因為當使用者啟動免持聽筒功能時,預期使用者在持用電子裝置進行語音通話時,即不會如圖3所示將電子裝置800與臉頰觸貼。Step 1600: Determine whether the electronic device activates the speakerphone function. When the electronic device activates the speakerphone function, the electronic device only needs to determine whether the user's voice signal is received during the response time, and skips the later first touch screen touch area size determination step 1710. Because when the user activates the speakerphone function, it is expected that the user does not touch the electronic device 800 with the cheek as shown in FIG. 3 when the user holds the electronic device for a voice call.

步驟1710:電子裝置偵測第一觸控螢幕於第一時間內被觸碰之面積大小是否超過第一面積。此處第一面積可設定為:一般使用者使用手指或觸控筆操作觸控螢幕時,在觸控螢幕所可能產生之最大面積。第一時間可被設定為1~2秒鐘。Step 1710: The electronic device detects whether the size of the area touched by the first touch screen in the first time exceeds the first area. The first area can be set as the maximum area that can be generated on the touch screen when the user touches the touch screen with a finger or a stylus. The first time can be set to 1~2 seconds.

步驟1910:當第一觸控螢幕於第一時間內被觸碰之面積超過第一面積時,推論係使用者臉頰接觸第一螢幕100;如此該電子裝置關閉第一觸控螢幕100之觸控功能電路,藉以避免通話時,因使用者臉頰接觸第一螢幕100而誤動作啟動其他操作,同時減少電力消耗。。Step 1910: When the area touched by the first touch screen exceeds the first area in the first time, it is inferred that the user's cheek contacts the first screen 100; thus the electronic device turns off the touch of the first touch screen 100. The function circuit, in order to avoid the call, causes the user's cheek to contact the first screen 100 and malfunctions to start other operations while reducing power consumption. .

步驟1720:電子裝置偵測於應答時間內是否接收到使用者說話之語音訊號。此處應答時間可被設定為:5~10秒鐘。Step 1720: The electronic device detects whether the voice signal of the user is received during the response time. The response time can be set to: 5~10 seconds.

步驟1920:當電子裝置於應答時間內有接收到使用者語音訊號時,推論使用者已經開始進行通話,暫時不需要螢幕顯示資訊;立即關閉第一螢幕100之部份觸控功能電路,背光源或顯示電路,以減少電力消耗。Step 1920: When the electronic device receives the user voice signal within the response time, it is inferred that the user has started the call, and the screen display information is not needed for the time being; the part of the touch function circuit of the first screen 100 is immediately turned off, and the backlight is turned off. Or display circuits to reduce power consumption.

步驟1930:當電子裝置於應答時間內沒有接收到使用者語音訊號時,則延遲10秒後關閉第一觸控螢幕100之部份觸控功能電路,背光源或顯示電路。Step 1930: When the electronic device does not receive the user voice signal within the response time, the touch control circuit, the backlight or the display circuit of the first touch screen 100 is turned off after 10 seconds delay.

此處所謂:關閉第一觸控螢幕100之部份背光源或顯示電路,具體可能之調整方式為:減低螢幕畫面顯示亮度、減少螢幕畫面顯示區域大小,減少所使用的畫素pixel等。同時因為第一觸控螢幕100畫面已經停止顯示,因此使用者難以辨識代表各種功能之圖標(icon),所以相對應螢幕區域的觸控功能電路同時也可以被關閉。Herein, the backlight or the display circuit of the first touch screen 100 is turned off. The specific adjustment methods are as follows: reducing the brightness of the screen display, reducing the size of the screen display area, and reducing the pixel size used. At the same time, since the first touch screen 100 screen has stopped displaying, it is difficult for the user to recognize the icon representing various functions, so the touch function circuit corresponding to the screen area can also be turned off at the same time.

如圖5A~5B所示之第二實施例,本發明之雙螢幕顯示裝置進入省電模式之控制方法,亦可針對第一觸控螢幕及該第二觸控螢幕是否相對展開,做更進一步細部的判斷步驟,區分成兩個不同的分支流程,包含:As shown in FIG. 5A to FIG. 5B, the dual-screen display device of the present invention enters a power-saving mode control method, and can further expand whether the first touch screen and the second touch screen are relatively unfolded. The detailed judgment steps are divided into two different branch processes, including:

步驟1200:在收到來電訊號後,判斷第一觸控螢幕及該第二觸控螢幕是否相對展開。Step 1200: After receiving the incoming call signal, determine whether the first touch screen and the second touch screen are relatively unfolded.

步驟1310:當第一觸控螢幕100及第二觸控螢幕200係為相對展開狀態時,關閉第二觸控螢幕之觸控功能電路及顯示電路。當電子裝置接受來電訊號時,只要把代表通話鍵之圖標icon顯示在和聽筒與麥克風同側之第一觸控螢幕100上,如此即使僅第一觸控螢幕仍保持顯示及觸控功能,亦不影響使用者接聽電話之操作。因此,可關閉第二觸控螢幕之觸控功能電路及顯示電路,以避免因觸接第二觸控螢幕而啟動其他操作,並且達到省電功效。Step 1310: When the first touch screen 100 and the second touch screen 200 are in a relative unfolded state, the touch function circuit and the display circuit of the second touch screen are turned off. When the electronic device receives the incoming call signal, the icon icon representing the call button is displayed on the first touch screen 100 on the same side of the handset and the microphone, so that even if only the first touch screen remains displayed and touched, Does not affect the user's operation to answer the call. Therefore, the touch function circuit and the display circuit of the second touch screen can be turned off to avoid starting other operations by touching the second touch screen, and achieving power saving effect.

步驟1320:當第一觸控螢幕及第二觸控螢幕係為相背對之疊合狀態時,雙螢幕顯示裝置繼續偵測第二觸控螢幕200是否向上。其中,如圖6A至圖6C所示,當第二觸控螢幕法線201與向上垂直線600之夾角θ小於第一觸控螢幕法線101與向上垂直線600之夾角γ時,第二觸控螢幕係為向上。Step 1320: When the first touch screen and the second touch screen are in a folded state, the dual screen display device continues to detect whether the second touch screen 200 is up. As shown in FIG. 6A to FIG. 6C, when the angle θ between the second touch screen normal 201 and the upward vertical line 600 is smaller than the angle γ between the first touch screen normal 101 and the upward vertical line 600, the second touch The control screen is up.

步驟1321:當第二觸控螢幕係為向上時,雙螢幕顯示裝置繼續偵測第二觸控螢幕100於第二時間內被觸碰之面積大小是否大於第二面積。因為當第一觸控螢幕及第二觸控螢幕係為相背對疊合狀態且第二觸控螢幕係為向上時,預期使用者可能會用手掌握持第二觸控螢幕來拿起電話以進行通話;因此當第二觸控螢幕於第二時間內被觸碰之面積大於第二面積時,則判定第二觸控螢幕係與使用者手掌接觸。第二時間可被設定為:20秒鐘。Step 1321: When the second touch screen is up, the dual screen display device continues to detect whether the size of the area touched by the second touch screen 100 in the second time is greater than the second area. Because when the first touch screen and the second touch screen are opposite to each other and the second touch screen is upward, it is expected that the user may grasp the second touch screen by hand to pick up the phone. To make a call; therefore, when the area touched by the second touch screen in the second time is greater than the second area, it is determined that the second touch screen is in contact with the palm of the user. The second time can be set to: 20 seconds.

步驟1322:當第二觸控螢幕於第二時間內被觸碰之面積大於第二面積時,關閉第二觸控螢幕之觸控功能電路及顯示電路,以避免因使用者手掌接觸第二觸控螢幕而啟動其他操作,並且達到省電功效。Step 1322: When the area touched by the second touch screen is greater than the second area in the second time, the touch function circuit and the display circuit of the second touch screen are turned off to avoid contact with the second touch by the user's palm. Control the screen to start other operations and achieve power saving.

步驟1500:在通話功能啟動步驟1400之後,判斷第一觸控螢幕及第二觸控螢幕是否自原本的相對展開狀態闔起。當第一觸控螢幕及第二觸控螢幕仍維持相對展開狀態時,該電子裝置僅需判斷於一應答時間內是否接收到該使用者說話之語音訊號,意即略過免持聽筒功能判斷步驟以及第一觸控螢幕觸碰判斷步驟。Step 1500: After the call function starting step 1400, it is determined whether the first touch screen and the second touch screen are picked up from the original relative deployment state. When the first touch screen and the second touch screen remain in the relative unfolded state, the electronic device only needs to determine whether the user's voice signal is received during a response time, that is, the speaker function is skipped. The step and the first touch screen touch judgment step.

如圖3所示,預期使用者若想要將電子裝置移到臉頰旁之位置進行語音通話時,則使用者通常會將第一觸控螢幕100及第二觸控螢幕200自相對展開狀態闔起,以便於單手握持使用。換言之,若第一觸控螢幕100及第二觸控螢幕200維持相對展開狀態,則使用者在持用電子裝置進行語音通話時,應該不會將電子裝置移到臉頰旁之位置,因此不會發生如圖3所示電子裝置800與臉頰接觸誤動作之狀況。因此當第一觸控螢幕及第二觸控螢幕仍維持相對展開狀態時,可直接略過免持聽筒功能判斷步驟1600以及第一觸控螢幕觸碰判斷步驟1710。As shown in FIG. 3, if the user wants to move the electronic device to the position next to the cheek for a voice call, the user usually displays the first touch screen 100 and the second touch screen 200 from a relative deployment state. Start up for one-handed use. In other words, if the first touch screen 100 and the second touch screen 200 are maintained in a relative unfolded state, the user should not move the electronic device to the position beside the cheek when holding the electronic device for a voice call, and thus will not A situation in which the electronic device 800 is in contact with the cheek as shown in FIG. 3 occurs. Therefore, when the first touch screen and the second touch screen remain in the relative unfolded state, the hands-free function determining step 1600 and the first touch screen touch determining step 1710 can be directly skipped.

如圖1A~1B及圖7A所示,在第三實施例中,控制器400偵測並分別如步驟1580及步驟1780所述判斷第二觸控螢幕200由第一相對位置701移動至第二相對位置702之第一時點,與自第一時點起使用者係先觸碰第一觸控螢幕100或第二觸控螢幕200而產生觸碰訊號。換言之,控制器400偵測並判斷第一觸控螢幕100及第二觸控螢幕200由相對展開狀態變成相背對疊合狀態之第一時點,與自第一時點起,使用者係先觸碰第一觸控螢幕100或第二觸控螢幕200而產生觸碰訊號。As shown in FIGS. 1A-1B and FIG. 7A, in the third embodiment, the controller 400 detects and determines that the second touch screen 200 moves from the first relative position 701 to the second as described in step 1580 and step 1780, respectively. At the first time relative to the position 702, the user first touches the first touch screen 100 or the second touch screen 200 from the first time point to generate a touch signal. In other words, the controller 400 detects and determines that the first touch screen 100 and the second touch screen 200 change from the relative unfolded state to the first time point of the opposite back state, and from the first time point, the user system The first touch screen 100 or the second touch screen 200 is touched first to generate a touch signal.

控制器400根據第一時點及觸碰訊號係源自於第一觸控螢幕100或第二觸控螢幕200,調整第一觸控螢幕100及第二觸控螢幕200之作動。其中,作動包含前述關閉螢幕之顯示以達到省電效果。具體而言,雙螢幕顯示裝置800更包含第一觸控螢幕顯示電路110。當使用者先觸碰第一觸控螢幕100,亦即第一觸控螢幕100於第一時點上或第一時點後首次產生觸碰訊號,則控制器400會如步驟1921所述關閉第一觸控螢幕顯示電路110,使第一觸控螢幕100之顯示關閉。相對的,雙螢幕顯示裝置800更包含第二觸控螢幕顯示電路210,若使用者先觸碰第二觸控螢幕200,亦即第二觸控螢幕200於第一時點上或第一時點後首次產生觸碰訊號,則控制器400會如步驟1922所述關閉第二觸控螢幕顯示電路210,使第二觸控螢幕200之顯示關閉。本實施例係假設該第一時點後所產生的首次觸碰訊號,係對應到使用者想要握持該電子裝置時,使用者手掌與觸控螢幕的首次接觸。因此產生首次觸碰訊號的那一面螢幕並非使用者觀看中的螢幕,而可以被關閉。The controller 400 adjusts the actuation of the first touch screen 100 and the second touch screen 200 according to the first time screen and the touch signal from the first touch screen 100 or the second touch screen 200. The actuation includes the display of the aforementioned off screen to achieve a power saving effect. Specifically, the dual screen display device 800 further includes a first touch screen display circuit 110. When the user first touches the first touch screen 100, that is, the first touch screen 100 first generates a touch signal at the first time point or after the first time point, the controller 400 turns off as described in step 1921. The first touch screen display circuit 110 turns off the display of the first touch screen 100. In contrast, the dual screen display device 800 further includes a second touch screen display circuit 210. If the user touches the second touch screen 200 first, that is, the second touch screen 200 is at the first time or the first time. After the touch signal is generated for the first time after the point, the controller 400 turns off the second touch screen display circuit 210 as shown in step 1922 to turn off the display of the second touch screen 200. In this embodiment, it is assumed that the first touch signal generated after the first time point corresponds to the first contact between the user's palm and the touch screen when the user wants to hold the electronic device. Therefore, the screen on which the first touch signal is generated is not the screen that the user is watching, but can be turned off.

相反地,亦可視使用者個人使用習慣,而重新設定被觸控之觸控螢幕與被關閉顯示之觸控螢幕之對應關係。例如:使用者手掌較大,握持電子裝置時,使用者手掌並不會與任一觸控螢幕接觸,而是五指分別握在電子裝置的左右兩側面。如此該第一時點後所產生的首次觸碰訊號,係對應到使用者握持該電子裝置後,使用者手指或觸控筆與觸控螢幕的首次接觸。因此產生首次觸碰訊號的那一面螢幕正是使用者觀看中的螢幕,而相對面螢幕可以被關閉。Conversely, the corresponding relationship between the touched touch screen and the touch screen that is turned off can be reset according to the user's personal usage habits. For example, when the user's palm is large, when the electronic device is held, the palm of the user does not touch any touch screen, but the five fingers are respectively held on the left and right sides of the electronic device. The first touch signal generated after the first time point corresponds to the first contact of the user's finger or the stylus with the touch screen after the user holds the electronic device. Therefore, the screen on which the first touch signal is generated is the screen that the user is watching, and the opposite screen can be turned off.

在圖7B第四實施例中,當使用者先觸碰第二觸控螢幕200,則控制器400會關閉第一觸控螢幕顯示電路110,使第一觸控螢幕100之顯示關閉。或當使用者先觸碰第一觸控螢幕100,則控制器400會關閉第二觸控螢幕顯示電路210,使第二觸控螢幕200之顯示關閉;或當使用者先觸碰第二觸控螢幕200,則控制器400會關閉第二觸控螢幕顯示電路210,使第二觸控螢幕200之顯示關閉。In the fourth embodiment of FIG. 7B, when the user first touches the second touch screen 200, the controller 400 turns off the first touch screen display circuit 110 to turn off the display of the first touch screen 100. Or when the user first touches the first touch screen 100, the controller 400 turns off the second touch screen display circuit 210 to turn off the display of the second touch screen 200; or when the user first touches the second touch When the screen 200 is controlled, the controller 400 turns off the second touch screen display circuit 210 to turn off the display of the second touch screen 200.
