Those skilled in the art can understand that the structure of the mobile phone 100 shown in FIG. 1 does not constitute a limitation on the mobile phone, and may include more or less components than shown in the figure, or a combination of certain components, or different component arrangements. The following uses a terminal as an example to illustrate the technical solution of the present invention, where the terminal is not limited to being applied to a mobile phone, but can also be applied to a tablet computer and the like.

AOD, always on display, is called off-screen display (or off-screen display). The AOD interface refers to the interface displayed when the terminal is in AOD mode. When the terminal is in the AOD mode, the terminal will still display some common information on the screen after the screen is turned off. For example, the AOD interface can display power, time, important notification reminders, etc. Since in the AOD mode, the user can directly see the above information without touching the terminal with his hand, which reduces the user's operation steps and provides great convenience.

The terminal in the AOD mode is usually in a locked screen state, so when a user needs to use an application in the terminal, it is usually necessary to perform a corresponding unlock operation on the terminal, and then exit the current AOD interface and display the required interface UI. For this process, the problem of interface switching and display is involved. However, for the switching display process, the existing solution is mainly to draw and synthesize the display interface through the upper UI application in the system, and send the synthesized data into the display buffer (ie framebuffer), and finally display it on the screen. .

For example, when the terminal is successfully unlocked, the AOD interface needs to be switched to display the system default interface (hereinafter referred to as desktop UI), as shown in Figure 2, the existing solution process mainly includes:

1) Destroy the AOD interface;

2) Create a desktop UI;

3) Send the created desktop UI data to the display cache;

4) Send the data in the display buffer to display, that is, send it to the screen for display.

Among them, the above two steps of destroying the AOD interface and creating the desktop UI can be performed in an agreed sequence or simultaneously.

For the existing solution, when creating the desktop UI, the desktop UI needs to be drawn through the upper Canvas first, and after the AOD interface is destroyed, the upper SurfaceFlinger synthesizes the two interfaces, and then sends the synthesized data to the display The framebuffer is cached and finally displayed on the screen. Among them, when sending data to the framebuffer, the upper Surfaceflinger mainly sends the data to be displayed to the framebuffer through an interface call.

It can be seen that each switching display needs to be drawn and synthesized by the upper application, and during the interface switching process, the previous interface needs to be destroyed in time to ensure the normal display of the latter interface. Therefore, this solution will extend the desktop The UI display time, for the user, the intuitive feeling is that the terminal is slow in unlocking, and the response of exiting the AOD interface is not sensitive enough.

For this reason, the present invention proposes a new solution to solve the above-mentioned problems, which can speed up the display speed of the terminal interface after unlocking, and improve the user experience.

The present invention will be described below with specific embodiments. Of course, the present invention is not limited to these specific embodiments.

Example 1

3, this embodiment proposes a screen display method, which can be applied to terminals, such as mobile phones, tablet computers, and other electronic devices that can be unlocked and displayed on the interface through a touch screen.

In step S100, when a successful unlocking operation of the terminal is detected, the current AOD interface is hidden and the target interface hidden under the AOD interface in advance is displayed.

Exemplarily, the target interface refers to the interface presented to the user at the first time after the user unlocks the terminal. For example, it can be the system desktop UI or the related application interface that was displayed when the screen was last locked. The application is directly locked without exiting in time. After the unlocking is successful, the application interface that was displayed last time will continue to be displayed.

It can be understood that, before the successful unlocking operation in step S100 is detected, the terminal is in the AOD mode and displays the aforementioned AOD interface.

In the above step S110, after the successful unlocking is detected, that is, after the user identity is successfully recognized, the display will be switched to the target interface. In order to display the target interface, this embodiment first hides the target interface under the AOD interface, and then after the unlocking is successful, the AOD interface is hidden and the target interface is controlled to be directly displayed.

In this embodiment, the so-called hiding of the current AOD interface means that the AOD interface is not destroyed before the target interface appears, and the AOD interface and the target interface are combined together and sent to the display buffer.

In this embodiment, the target interface will be located below the AOD interface, which can be understood as setting the adjacent layer position of the target interface and the AOD interface, and the layer of the AOD interface is located above the layer of the target interface. Before the terminal is unlocked from the beginning to unlock successfully, the AOD interface will continue to be displayed and the target interface located below it will be blocked. After the unlocking is successful, the AOD interface at the top is immediately hidden and the target interface is displayed.

In an embodiment, for the above-mentioned target interface and AOD interface set as adjacent layers, the addresses of the AOD interface and the target interface adjacent to the AOD interface in the display cache can be mapped together or respectively mapped to The engine of the display.

Exemplarily, as shown in FIG. 4, the data of the AOD interface and the target interface are made to correspond to two different addresses in the display buffer (framebuffer), and then the two different addresses are mapped together or respectively to the terminal's On the engine of the monitor. Of course, in some embodiments, the addresses of the AOD interface and the target interface adjacent to the AOD interface in the display cache may also be mapped to different engines of the display respectively.

The terminal usually includes upper-layer applications and lower-layer hardware. It should be understood that the display includes hardware display components including a display screen at the bottom layer, a display driver, a display processing unit DPU, and an image processing unit GPU. The engine refers to the image processing engine at the bottom layer for controlling the display of layer data. It can complete image processing by using the hardware image processing unit GPU and/or display processing unit DPU and send the processed data directly framebuffer. Among them, different layers can correspond to different engines.

When the terminal is successfully unlocked, the system can switch the display by notifying the underlying display. Since the AOD interface and the target interface are set with corresponding engines, the transparency of the engine corresponding to the AOD interface can be set to a transparent state, so that the AOD interface The data is not visible.

Exemplarily, the transparency of the engine can be adjusted by the alpha blending method, and the background and foreground of the AOD interface can be set with different alpha values and mixed, so that the AOD interface can be set to be transparent. Generally, the alpha value ranges from 0 to 1. When the alpha value is 0, the transparency of the engine is transparent; when the alpha value is 1, it is opaque.

For example, in the Android system, the transparency is expressed in hexadecimal, and the transparency is divided into 255 levels, where the transparency of 100% is 00, and the transparency of 0% is FF. It can be understood that how to set the transparency of the engine to a transparent state can be determined according to the actual scene, which is not limited here.

Therefore, after setting the data of the AOD interface to be invisible, the AOD interface and the target interface are mixed, and the mixed data is displayed.

Exemplarily, using the same or separate image processing engines to mix the data of the two interfaces, the cached data in the framebuffer will be updated accordingly. In addition, if there are other interface data located below the target interface, they can also be mixed together.

Among them, the framebuffer is a frame buffer allocated by the system for display data. Finally, through the interface of refreshing the display screen, the updated data in the framebuffer can be directly sent to the display screen for display.

It should be understood that the screen display method proposed in this embodiment does not need to wait for the upper layer application to perform operations such as drawing and compositing, but directly controls the underlying hardware to complete the switching display of the interface. In the actual test process, compared with the existing switching display process, the entire switching display process can be shortened by 50ms to 80ms.

In an embodiment, when the terminal displays the AOD interface, it is in the AOD mode, as shown in FIG. 5, the screen display method further includes:

Step S100: It is detected whether there is an unlocking operation on the terminal.

Exemplarily, the unlocking operation may include, but is not limited to, fingerprint unlocking, key unlocking, facial recognition unlocking, and the like. For example, the fingerprint unlocking can be divided into under-screen fingerprint unlocking or off-screen fingerprint unlocking.

Among them, the main principle of under-screen fingerprint unlocking is to perform user fingerprint identification through a hidden fingerprint identification sensor located at the bottom of the screen. The off-screen fingerprint unlocking is other fingerprint unlocking methods besides the under-screen fingerprint unlocking, for example, by setting the fingerprint recognition sensor below the panel of the visible home button or touch virtual key on the terminal.

In step S101, if it exists, it is determined whether the current unlocking operation matches the preset unlocking operation.

Generally, the terminal can have multiple unlocking methods at the same time. For the above step S101, when judging whether it matches, it needs to be matched according to the actual unlocking operation. For example, if it is an under-screen fingerprint unlocking operation, the fingerprint information obtained by the under-screen fingerprint recognition sensor is compared with the pre-stored authenticated fingerprint. If the comparison is successful, step S102 is executed, otherwise, step S103 is executed.

In step S102, if it matches, it is determined that the unlocking is successful.

After the unlocking is successful, step S110 is executed, that is, an interface switching display operation is performed.

In step S103, if it does not match, it is determined that the unlocking has failed, and the AOD interface is continued to be displayed.

If the unlocking is unsuccessful, the current AOD interface will continue to be displayed. Of course, a message reminder of the unlocking failure can also be popped up. For non-matching responses, specific settings can be made according to actual needs, and there is no specific limitation here.

Regarding the process of the terminal switching and displaying the target interface from the AOD interface, the screen display method proposed in this embodiment changes the switching display process, that is, directly uses the underlying hardware to display the switching, without the need for drawing and synthesis through the upper application , Which speeds up the display of the target interface after unlocking, thereby greatly improving the user experience and so on.
