Detailed ways

In order to solve the display problem of the terminal with at least two independent screens in the related art, the first embodiment of the present disclosure provides a screen display method. The method is shown in FIG. 1 and includes steps S102, S104 and S106:

S102. Receive a first trigger signal. In this embodiment, the first trigger signal may include, but is not limited to, a user clicking a power button of the mobile terminal, a user applying a fingerprint on the mobile terminal, a message such as a short message, and a third party installed on the mobile terminal. Application notifications, etc.

S104. Detect whether the first screen of the mobile terminal and the second screen of the mobile terminal are both in a screen-off state.

In this embodiment, the screen of the mobile terminal is in a screen-off state, and the screen may be closed when the mobile terminal is in the standby state; the user may click the power button of the mobile terminal to make the screen go out; After that, because the mobile terminal sets the automatic black screen time, the screen is black. The above several situations can be called the screen-off state. Taking the terminal using the Android system as an example, in the source code of the Android system, the explanation of the screen-off state is: SCREEN_OFF. Since the dual-screen mobile terminal can be folded or unfolded and has two display screens, it corresponds to a plurality of different screen display modes when the mobile terminal is in different states.

S106. When the first screen and the second screen are both in the off-screen state, the first screen and the second screen are lit, and the display corresponding to the first trigger signal is displayed on the first screen and/or the second screen. content.

After the mobile terminal receives the trigger signal, the two screens in which the mobile terminal is in the off state will be illuminated at the same time. At this time, the trigger signal may be displayed on any one of the two screens or simultaneously on the two screens. Display content. For example, the two screens of the mobile terminal are in the off state. If the mobile terminal has a phone call in at this time, then the two screens are simultaneously illuminated. At this time, the gravity sensor can determine which screen is on, and the screen is on the screen. The interface for answering the call is displayed; of course, after the two screens are simultaneously illuminated, the interface for answering the call can be simultaneously displayed on the two screens, so that when the user takes out the mobile terminal, the first time is seen The main screen or the secondary screen can be seen in time when someone is calling, and the user can operate on any screen to answer or refuse to answer the call.

The screen display method provided by the embodiment, after receiving the first trigger signal, detects whether both screens are in the off state. If the detection result is yes, after the mobile terminal receives the first trigger signal, it displays on the screen. The display content corresponding to the trigger signal. This method can make the two screens display content freely, flexibly utilize the screen, and not waste screen resources, and solve the display problem of the terminal with at least two independent screens in the related art.

When detecting whether the first screen and the second screen of the mobile terminal are in a screen-off state, whether the mobile terminal is in a folded state may be detected first, and if the mobile terminal is in a folded state, detecting the Whether the first screen and the second screen of the mobile terminal are both in the off state.

When the mobile terminal is in the folded state, it is detected whether both screens of the mobile terminal are in the off state. When both screens are in the off state, the mobile terminal can display the display content corresponding to the trigger signal on both screens. This method enables the mobile terminal to simultaneously respond to the triggering operation when the mobile terminal is in the folded state, and both screens can be operated by the user, thereby significantly improving the user experience.

In this embodiment, when the mobile terminal is in the folded state, there is also a case that if only one of the two screens is in the off-screen state, after receiving the trigger signal, the screen is directly in the original state. The display content corresponding to the trigger signal is displayed on the screen.

For example, when a dual-screen phone is in an expanded state, the user uses one of the screens to play the game while the other screen is off. In order to operate the mobile phone conveniently, the user folds the mobile phone and folds it to continue playing the game on this screen. At this time, a phone calls into the mobile phone, and the mobile phone saves the progress of the game. The display interface of the call answering will only be displayed on the screen where the user is playing the game. The user can directly operate on this screen, select to answer or hang up. phone. The above settings can make the mobile phone run more efficiently, and at the same time, it is convenient for the user to operate the mobile phone, thereby improving the user experience. In this embodiment, there is another case, after one screen displays the display content corresponding to the trigger signal, another screen that is previously in the off-screen state may be lit, and the trigger signal is displayed. Corresponding display content. The specific process is: the operating system of the mobile terminal detects whether the screen in the off-screen state receives the lighting signal, and when it receives the lighting signal, lights the screen and displays the first trigger signal thereon. Corresponding display content.

For example, when the dual-screen mobile phone is in a folded state, the user is viewing the e-book with one screen, and the mobile phone receives a short message, and the short message notification is displayed on the screen. The user wants to keep the current e-book page displayed, and does not want to use this. The screen can view the short message. At this time, the user can light another screen to display the content of the short message. This way, the user can flexibly select which screen to view the display content corresponding to the first trigger signal according to actual needs when the dual-screen mobile phone is folded. Significantly improved user experience.

After the first trigger signal causes the screen of the mobile terminal to display the corresponding display content, it may further detect whether the screen displaying the display content corresponding to the first trigger signal receives the second trigger signal, and when detecting that the first trigger signal is displayed, When the screen displaying the content receives the second trigger signal, performing an operation corresponding to the second trigger signal on the screen receiving the second trigger signal, and switching the desktop launcher of the mobile terminal to the received The screen that triggers the signal and sends a clear signal to the other screen to close the other screen.

For example, if both screens display the display content corresponding to the first trigger signal, it is detected whether any of the two screens receives the second trigger signal, and if one screen receives the second trigger signal, then The operation corresponding to the second trigger signal is performed on the screen receiving the second trigger signal, and the screen blank signal is sent to the other screen to close the screen. The second trigger signal refers to a user clicking, sliding, etc. on a screen, and detecting whether the screen receives the second trigger signal, in order to determine which screen the user operates on, after determining that the user operates one of the screens. , close another screen. The above process can save the power of the mobile terminal and increase the degree of freedom for the user to operate the mobile terminal, thereby improving the user experience.

For example, when the dual-screen mobile phone is in the folded state, both screens are in the off-screen state, and the dual-screen mobile phone receives a short message, and the short message receiving notification simultaneously lights the two screens, and the notification is in two. Displayed on both screens. At this point, the user takes the dual-screen phone to his hand and clicks on his face to view the short message. In this case, the content of the short message will be completely displayed on the screen that the user clicks, and the other screen will be closed. In the above process, the user clicks on the operation from the face of the screen, that is, the second trigger signal in this embodiment. In addition, the second trigger signal may also be an operation of the user sliding one of the screens in order to answer the call when the dual-screen mobile phone calls. The second trigger signal may also be an operation performed when the dual screen mobile phone receives the application notification, the user does not want to view the notification temporarily, and clicks the ignore option on the notification bar. In summary, the second trigger signal refers to a corresponding operation performed by the user on the dual-screen mobile phone in response to the first trigger signal.

In addition, in this embodiment, if the mobile terminal is in the unfolded state, when the screen receives the first trigger signal, the display content corresponding to the first trigger signal may also be displayed on the first screen and/or the second screen. The first trigger signal may include: clicking a power button, unlocking a fingerprint, or receiving a short message. Such a setting enables the two screens of the mobile terminal to be arbitrarily displayed and operated, and the operation of any screen can realize all the functions of the mobile terminal, providing the user with more choices and more free operation modes, thereby significantly improving User experience and improve the efficiency of dual-screen use of mobile terminals.

The existing dual-screen mobile phone will limit one of the screens to the main screen, and the other screen to the secondary screen. In general, the material colors of the main screen and the secondary screen of the mobile phone are all the same, which is easy to confuse the user. By using the embodiment, when the user takes out the mobile phone, even if the main screen and the sub screen cannot be distinguished, the user's use is not affected. For example, when the user operates the mobile phone, such as when the mobile phone power button is clicked, even if the secondary screen of the dual-screen mobile phone faces the user at this time, the secondary screen is illuminated for content display; and the user can also operate on the secondary screen. To enhance the user experience.

A second embodiment of the present disclosure provides a screen display device. The structure of the device is as shown in FIG. 2, and the device includes: a signal receiving module 10 configured to receive a first trigger signal; and a first detecting module 20, The signal receiving module 10 is coupled to be configured to detect whether the first screen and the second screen of the mobile terminal are both in a screen-off state; the first display module 30 is coupled to the first detecting module 20, configured to be in the first screen and the first In a case where both screens are in the off-screen state, the first screen and the second screen are illuminated, and the display content corresponding to the first trigger signal is displayed on the first screen and/or the second screen.

In this embodiment, the first trigger signal may include, but is not limited to, the user clicks the power button of the mobile terminal; the user performs fingerprint unlocking on the mobile terminal; the message of the system application such as an incoming call or a short message, and the number installed on the mobile terminal. Notification of three-party application, etc.

Since the dual-screen mobile terminal can be folded or unfolded and has two display screens, the mobile terminal corresponds to a plurality of different screen display modes in different states. The first detecting module can detect whether the mobile terminal is in a folded state, in addition to detecting whether the first screen and the second screen of the mobile terminal are in a blanking state; and in the case that the mobile terminal is in a folded state, the first detecting module can also Whether the screens are in the off state for detection, to determine which mode can be used for the screen display.

After receiving the first trigger signal, the first display module may cause the two screens in which the mobile terminal is in the off-screen state to be illuminated at the same time, and display the display content corresponding to the trigger signal. For example, the mobile terminal is in a folded state and both screens are in a screen-off state. If the mobile terminal has a phone call in at this time, both screens will be lit at the same time and the phone answering interface is displayed at the same time, and the user takes out the mobile terminal. Whenever you see the main screen or the secondary screen in the first time, you can see that someone is calling at this time, and the user can operate on any screen to answer or reject the call.

When the mobile terminal is in the folded state, there is also a case that if one of the two screens is in the off state, after receiving the trigger signal, the first display module can directly display the screen that is originally in the bright state. The display content corresponding to the trigger signal.

In this embodiment, when the mobile terminal is in the folded state, there is another situation. After one of the screens displays the display content corresponding to the trigger signal, another screen that is previously in the off state may be lit. And displaying the display content corresponding to the trigger signal, the specific process is: detecting, by the second detecting module (coupled with the first display module 30), whether the screen in the off-screen state receives the lighting signal, and receiving the lighting signal In the case of the lighting signal, the second display module (coupled with the second detecting module) lights up the screen and displays the display content corresponding to the first trigger signal thereon. In a specific implementation, the first display module and the second display module may be set to be the same display module when being set.

After the first trigger signal causes both screens of the mobile terminal to display their corresponding display contents, the user also performs subsequent operations on the mobile terminal to process the response caused by the first trigger signal on the mobile terminal. In this embodiment, the screen display manner in the above process may be defined as follows: the third detection module (coupled with the first display module 30) detects whether the screen displaying the display content corresponding to the first trigger signal is received. Go to the second trigger signal, if the screen receives the second trigger signal, the screen corresponding to the second trigger signal is performed on the screen by the screen closing module (coupled with the third detecting module), and the screen is sent to the other screen. Signal to turn off another screen. The second trigger signal refers to a user clicking, sliding, and the like on a screen, and the third detecting module detects whether the screen receives the second trigger signal, in order to determine that the user responds to the screen response triggered by the first trigger signal. Which screen to operate on. After detecting that the user operates one of the screens, the screen closing module turns off another screen, which not only saves the power of the mobile terminal, but also increases the degree of freedom for the user to operate the mobile terminal, thereby improving the user experience.

After the above process, the user selects a screen to operate, in order to enable the user to continue to perform other operations on the screen after the operation in response to the first trigger signal, in order to use the mobile terminal normally, it is necessary to enable the screen to be enabled. The main interface of the mobile terminal operating system is displayed, and various functions of the mobile terminal are used through the main interface. Therefore, in the present embodiment, after the user selects a screen and the screen performs the second triggering operation, the screen closing module should also cause the Launcher to switch to the screen on which the user operates.

For example, when a dual-screen mobile phone receives an application notification from a client of Taobao (an e-commerce platform), the notification content is that the seller of the product purchased by the user has already shipped, and the notification is simultaneously displayed on two screens, and the user clicks on one screen. The notification is displayed, and the Taobao client is opened on this screen to view the content of the notification. At this time, another screen will be closed, and the Launcher will switch to the screen that the user clicked, and the process of switching is performed in the background. , will not affect the user to view this notification. If the user wants to open the express client to query the specific logistics information after viewing the Taobao notification, then the user exits the Taobao client, and the main interface of the mobile operating system is displayed on this screen. The user can click the icon of the courier client on the main interface, enter the courier number on the client, and query the specific logistics information. The above settings enable the user to operate the mobile phone through any screen of the dual-screen mobile phone, and enable any screen of the mobile phone to completely display the interface of the mobile operating system, so that the user can operate the mobile phone according to actual needs, thereby significantly improving the user experience.

The screen display device provided in this embodiment may be disposed in a terminal. Therefore, the embodiment further provides a mobile terminal, where the mobile terminal includes at least a processor and a memory, and the processor is configured to execute a program of the screen display device stored in the memory. To achieve the above process.

The screen display device provided by the second embodiment of the present disclosure receives the first trigger signal by the signal receiving module, and then the first detecting module detects whether the first screen and the second screen of the mobile terminal are in the off state, if two The screens are all in the off-screen state, and the first display module lights up the two screens and displays the display content corresponding to the first trigger signal on the first screen and/or the second screen. The device can make the two screens display content freely, utilize the screen flexibly, and not waste screen resources, and solve the display problem of the terminal with at least two independent screens in the related art.

The third embodiment of the present disclosure provides a screen display method, such that when a signal such as an incoming call is triggered to trigger the mobile terminal, both screens can display the display content corresponding to the trigger signal, and the user can view and perform corresponding operations through any screen. The specific plan is as follows:

In the case of a dual-screen mobile terminal, the two screens A and B will be juxtaposed together. In the actual application, if the A screen is set as the main screen, the B screen is set as the sub screen, and the A screen and the B screen are displayed. The schematic diagram of the mode is shown in Figure 3 to Figure 6:

1. Single A mode: As shown in FIG. 3, the display of the content of the mobile terminal is concentrated on the main screen, and the operation of the mobile terminal by the user is also implemented through the main screen.

2. AB mode: When the mobile terminal is deployed, the two screens can display different contents at the same time. For example, when the user opens two applications at the same time, the interfaces of the two applications can be respectively displayed on two screens, and the display effect is as follows. Figure 4 shows.

3. Full A mode: When the mobile terminal is deployed, the two screens can be used as one screen to display an interface, as shown in FIG. 5.

4. Dual A mode: As shown in FIG. 6, when the mobile terminal is deployed, the same content can be displayed on two screens, and the user can operate any one of the screens to control the mobile terminal.

In addition to the above modes, the screen display method of the present embodiment provides a new display mode, and a schematic diagram of a display process corresponding to the mode is shown in FIG. That is, when the mobile phone is in a folded state, if the user clicks the power button, the fingerprint is unlocked, or there is a system and third party application notification, the A screen and the B screen are simultaneously lit, and the screen is clicked by the user, and the screen is operated as the main screen, and The main screen is displayed on this screen while the other screen is closed.

In order to implement the above process, the flowchart of the screen display method provided by this embodiment is as shown in FIG. 8, and includes steps S801 to S808:

S801, when the trigger signal occurs, detecting whether the mobile terminal is in the folding mode, and if yes, going to S803, otherwise going to S802.

In this embodiment, the trigger signal may be a power button, a fingerprint unlock, a call, a text message, an application notification, and the like. When the trigger signal triggers the dual-screen mobile phone, each screen has a magnet with a relative position on the back of the screen. It determines whether the dual-screen mobile phone is in a folded state according to whether the two magnets are attached to each other. Corresponding to the code, the relevant interface is called to return TRUE or FALSE. .

S802. If it is detected that the mobile terminal is in the unfolding mode, display content corresponding to the trigger signal is displayed on both the first screen and the second screen.

Since the mobile terminal is in the unfolded mode, the user can directly observe the state of the two screens. Therefore, when the mobile terminal is in the unfolding mode, the screen is not detected in the screen, but directly on the two screens. The display content corresponding to the trigger signal is displayed on the top. Of course, it can also be performed in the same manner as the folding state, that is, whether the two screens are in the off state regardless of whether it is the folding mode or not.

If the screen is expanded and the two screens are arranged side by side, the same display content corresponding to the trigger signal may be displayed by two screens, or the display content corresponding to the trigger signal may be displayed by any screen.

S803. Detect whether the two screens of the mobile terminal are in the off state. If yes, go to S805, otherwise go to S804.

If the mobile terminal is in the folding mode and both screens are in the off state, the mobile terminal is considered to be in the standby state, and if any of the two screens is not closed, the mobile terminal is considered not to be in the standby state.

S804: When the two screens of the mobile terminal are not in the off-screen state, the display content corresponding to the trigger signal is displayed on the screen that is lit at this time.

For example, when a dual-screen phone is in an expanded state, the user uses one of the screens to play the game while the other screen is off. In order to operate the mobile phone conveniently, the user folds the mobile phone and folds it to continue playing the game on this screen. At this time, a phone calls into the mobile phone, and the mobile phone saves the progress of the game. The display interface of the incoming call will only be displayed on the screen where the user is playing the game before, and will not be displayed at the same time before the other screen is off. On the screen, the user can directly operate on this screen, choose to answer or hang up the phone. The above settings can make the mobile phone run more efficiently, and at the same time, it is convenient for the user to operate the mobile phone, thereby improving the user experience.

S805. When the two screens of the mobile terminal are in the off state, the display content corresponding to the trigger signal is displayed on the first screen and/or the second screen.

When the mobile terminal is in the folded state and both screens are off, when there is a trigger signal, both screens can display the same display content corresponding to the trigger signal, and can also be displayed on one of the screens. In this case, during the execution of the corresponding code, a broadcast calling the dual A mode is issued, and the display display module (Display Manager) executes the dual A mode, and simultaneously outputs two identical data to the two screens, so that two The screens display the same content.

S806. Detect whether a screen displaying a content corresponding to the trigger signal receives a user trigger.

After receiving the trigger signal and determining the screen displaying the display content corresponding to the trigger signal, the user should normally select this screen for subsequent operations, and therefore should detect whether the screen receives the user trigger.

S807, if the screen displaying the corresponding content of the trigger signal receives the user trigger, performing an operation corresponding to the user trigger on the screen while closing another screen.

S808, switching the Launcher to receive a screen triggered by the user.

After the two screens display the same content, when the user clicks or slides one of the screens, the Launcher switches to this screen and closes the other screen. The process corresponding to the code execution is: which screen received the EVENT_TOUCH message, then the display mode is modified at this time, and another screen is closed, and singleAMode or singleBMode is called in the upper layer to display the Launcher interface on one screen, and the corresponding underlying processing. Yes: Do not provide a display data stream for another screen and leave it powered off.

In addition, the Launcher will display to the screen after the user has finished processing the trigger. If the mobile terminal is deployed, it is now possible to flexibly realize that the Launcher is displayed on a certain screen separately. In this embodiment, two screens can be displayed as one screen, and the display position of the Launcher interface can be flexibly adjusted to realize dynamic display, and the user only needs to move the screen, so that the Launcher can be separately displayed on a certain screen, thereby improving the user. Experience.

The screen display method provided in this embodiment detects whether the mobile terminal is in a folded state, and detects whether the two screens of the mobile terminal are in the off state when the mobile terminal is in the folded state, and if both screens are in the off state, After receiving the trigger signal, the display content corresponding to the trigger signal is displayed on the first screen and/or the second screen. If the user triggers one of the screens, the other screen is turned off; if any screen is not in the off state In the screen state, the display content corresponding to the trigger signal is displayed on the screen; if the mobile terminal is not in the folded state, when there is a trigger signal, the display corresponding to the trigger signal is displayed on the first screen and/or the second screen. content. This method can make the two screens display content freely, flexibly utilize the screen, and not waste screen resources, and solve the display problem of the terminal with at least two independent screens in the related art.

While the preferred embodiment of the present disclosure has been disclosed for purposes of illustration, those skilled in the art will recognize that various modifications, additions and substitutions are possible, and the scope of the present disclosure should not be limited to the embodiments described above.
