For detailed implementation of the display control method, reference may be made to the descriptions in the various embodiments below. In order to better understand the display screen control method provided in the embodiments of the present application, an application scenario of the display screen control method provided in the embodiments of the present application is described below with reference to fig. 1, fig. 2, and fig. 3.

In order to facilitate a user to learn about information of an electronic device, such as a date, a time, an incoming call, a push message, etc., without waking up the electronic device (i.e., without controlling the display screen of the electronic device to be on-screen), many electronic devices are configured with an all-day display (AOD, always On Display) function so that when the display screen of the electronic device is off-screen, an all-day display mode can be entered, and information such as a date, a time, an incoming call, a push message, etc., and an under-screen fingerprint unlock region are continuously displayed in an all-day display region. In the AOD mode, when a preset condition is triggered, the display screen can be controlled to be lightened, and the preset condition can be that a power key of the electronic equipment is triggered, the electronic equipment detects the lifting operation of a user, and the electronic equipment detects the operation of touching the display screen by the user. When the display screen is on, the power-on instruction is required to be sent based on the on state of the AOD function to control the display screen to be powered on, when the display screen is off, the power-off instruction is required to be sent based on the on state of the AOD function to control the display screen to be powered off, and the power-off instruction when the display screen is off and the power-on instruction when the display screen is on after the display screen is off have a one-to-one correspondence.

However, in the screen-off process, the on state of the AOD function may be changed, for example, the AOD function is originally turned on, when the electric quantity of the electronic device is too low, in order to save electricity, the AOD function is automatically turned off, and when the display screen is controlled to be on, a power-on instruction generated according to the on state of the AOD function does not correspond to a power-off instruction when the screen is off. That is, the power-on instruction actually generated when the screen is turned on after the screen is turned off may change along with the change of the on state of the AOD function, resulting in the failure of the power-on instruction when the screen is turned off, so that the display screen cannot be powered on when the screen is turned on, resulting in the failure of normal screen turning on of the display screen, and the display screen cannot respond to the operation of the user, resulting in the phenomenon of screen freezing, thereby affecting the user experience.

In an embodiment of the present application, the power-up Command and the power-down Command of the display screen are CMD (Command indicator) commands, for example, the power-up Command is CMD index1, and the power-down Command is CMD index2. The power-on instruction and the power-off instruction of the display screen are generated by an AOD management service (hwaodmaageservice), and the AOD management service generates the power-on instruction and the power-off instruction according to an on state or an available state of an AOD function and a fingerprint unlocking function (i.e., an off-screen fingerprint unlocking function) of the electronic device.

Referring to fig. 1, a schematic diagram of an off-screen display setting interface according to an embodiment of the present application is shown. The off-screen display setting interface comprises a control for controlling the off-screen display to be opened or closed and an option of an off-screen display mode, and when the off-screen display is opened and the off-screen display mode is full-day display, the AOD function of the electronic equipment is opened, namely the AOD function is available. When the AOD function or the fingerprint unlocking function of the electronic equipment is available, the AOD area or the fingerprint unlocking area needs to be continuously displayed, the power-down instruction is CMD 21, and the corresponding power-up instruction is CMD 22. When the display screen is controlled to be turned off, if the AOD function or the fingerprint unlocking function is available, the AOD management service generates a CMD 21 instruction as a power-down instruction and sends the CMD instruction to the display driving circuit to control the display screen to be powered down. When the display screen is controlled to be on, if the AOD function or the fingerprint unlocking function is available, the AOD management service generates a CMD 22 instruction as a power-on instruction and sends the CMD 22 instruction to the display screen driving circuit to control the power-on of the display screen.

Referring to fig. 2, another schematic diagram of an off-screen display setting interface according to an embodiment of the present application is shown. And when the off-screen display is closed or the off-screen display mode is not the full-day display, the AOD function of the electronic equipment is closed, namely the AOD function is unavailable. When the AOD function and the fingerprint unlocking function of the electronic equipment are unavailable, the AOD area and the fingerprint unlocking area do not need to be continuously displayed, the power-down instruction is CMD 20, and the corresponding power-up instruction is CMD 20. When the display screen is controlled to be turned off, if the AOD function and the fingerprint unlocking function are not available, the AOD management service generates a CMD 20 instruction as a power-down instruction and sends the CMD 20 instruction to the display screen driving circuit to control the display screen to be powered down. When the display screen is controlled to be on, if the AOD function and the fingerprint unlocking function are not available, the AOD management service generates a CMD 20 instruction as a power-on instruction and sends the CMD 20 instruction to the display screen driving circuit to control the power-on of the display screen.

Referring to fig. 3, a flowchart of sending a power-up instruction and a power-down instruction to a display screen according to an embodiment of the present application is shown. S101, judging whether an AOD function or a fingerprint unlocking function is available or not when a preset operation is detected. For example, the preset operation may be triggering a power key.

If neither the AOD function nor the fingerprint unlocking function is available, S102 is executed to generate a CMD 20 command, and the flow then proceeds to S106. If the AOD function or the fingerprint unlocking function is available, S103 is executed, and whether the preset operation is a screen-off operation is judged.

If the preset operation is not the off-screen operation, S104 is executed, it is determined that the preset operation is the on-screen operation, a CMD 22 command is generated, and then the flow proceeds to S106. If the preset operation is a screen-off operation, S105 is executed to generate a CMD 21 command.

And S106, sending the generated instruction to a display screen.

In an embodiment of the present application, the power-on instruction or the power-off instruction may be generated according to a determination result of whether the AOD function or the fingerprint unlocking function is available when the user performs the preset operation.

Referring to fig. 4, a schematic diagram of generating a power-on instruction and a power-off instruction according to an AOD function and a fingerprint unlocking function according to an embodiment of the present application is shown. When the screen-off operation is executed, a corresponding power-down instruction and power-up instruction are generated according to four conditions of availability of the AOD function and the fingerprint unlocking function, in the example of FIG. 4, AOD+ indicates that the AOD function is available, AOD-indicates that the AOD function is not available, finger+ indicates that the fingerprint unlocking function is available, and Finger-indicates that the fingerprint unlocking function is not available. Specifically, when the screen is turned off, if the AOD function and the fingerprint unlocking function are available, the power-down instruction is CMD 21, and when the screen is turned on under normal conditions, the AOD function and the fingerprint unlocking function are still available, and the power-up instruction is CMD 22 corresponding to the CMD 21; under abnormal conditions, after the electronic equipment enters a power saving mode due to the fact that the electric quantity is too low (for example, lower than 10%), when the electronic equipment is in a power saving mode, an AOD function is changed to be unavailable, a fingerprint unlocking function is still available, and a power-on instruction is CMD 22 corresponding to CMD 21. At this time, the power-up command CMD 22 corresponds to the power-down command CMD 21, and the display screen power-up can be controlled normally.

When the screen is turned off, if the AOD function is available and the fingerprint unlocking function is unavailable, the power-down instruction is CMD 21, and under normal conditions, when the screen is turned on, the AOD function is still available, the fingerprint unlocking function is still not available, and the power-up instruction is CMD 22 corresponding to the CMD 21; under abnormal conditions, the electronic equipment enters a power saving mode due to the fact that the electric quantity is too low, when the electronic equipment is in a screen-lighting mode, the AOD function is changed to be unavailable, the fingerprint unlocking function is still unavailable, and according to the available states of the AOD function and the fingerprint unlocking function, a power-on command is CMD 20 and is not corresponding to a power-off command CMD 21. At this time, the power-up command CMD 20 cannot control the power-up of the display.

When the screen is turned off, if the AOD function is unavailable and the fingerprint unlocking function is available, the power-down instruction is CMD 21, and when the screen is turned on under normal conditions, the AOD function is still unavailable, the fingerprint unlocking function is still available, and the power-up instruction is CMD 22 corresponding to the CMD 21; under abnormal conditions, the electronic equipment exits the power saving mode due to the fact that the electric quantity is increased (for example, the electric quantity of the electronic equipment is increased by charging the electronic equipment), when the electronic equipment is lightened, the AOD function is changed to be available, the fingerprint unlocking function is still available, and the power-on instruction is CMD 22 corresponding to CMD 21. At this time, the power-up command CMD 22 corresponds to the power-down command CMD 21, and the display screen power-up can be controlled normally.

When the screen is turned off, if the AOD function and the fingerprint unlocking function are not available, the power-down instruction is CMD 20, and under normal conditions, when the screen is turned on, the AOD function and the fingerprint unlocking function are not available, and the power-up instruction is CMD 20 corresponding to the CMD 20; under abnormal conditions, the electronic equipment exits from the power saving mode due to the increase of electric quantity, when the electronic equipment is on a screen, the AOD function is changed to be available, the fingerprint unlocking function is still not available, and according to the available states of the AOD function and the fingerprint unlocking function, the power-on command is CMD 22 and is not corresponding to the power-off command CMD 20. At this time, the power-up command CMD 22 cannot control the power-up of the display.

Based on the above example, after the display screen generates the power-on instruction according to the current available states of the AOD function and the fingerprint unlocking function to perform screen-off, the available states of the AOD function and the fingerprint unlocking function may be changed (for example, the available states of the electronic device are changed due to electric quantity change), so when the display screen is on, if the power-on instruction is generated according to the changed available states of the AOD function and the fingerprint unlocking function, the power-on instruction may not correspond to the power-off instruction when the screen is off last time, and the display screen on cannot be controlled normally.

Referring to fig. 5, a software architecture diagram of an electronic device according to an embodiment of the present application is shown. The layered architecture divides the software into several layers, each with distinct roles and branches. The layers communicate with each other through a software interface. For example, the Android system is divided into four layers, namely, an application layer 101, a framework layer 102, an Android runtime (Android run) and system library 103, a hardware abstraction layer 104, a kernel layer 105 and a hardware layer 106 from top to bottom.

The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction. Such as notification manager is used to inform that the download is complete, message alerts, etc. The notification manager may also be a notification in the form of a chart or scroll bar text that appears on the system top status bar, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

Android run time includes a core library and virtual machines. Android run time is responsible for scheduling and management of the Android system. The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer 101 and the framework layer 102 run in virtual machines. The virtual machine executes java files of the application program layer and the framework layer as binary files. The virtual machine is used for executing the functions of object life cycle management, stack management, thread management, security and exception management, garbage collection and the like.

The system library 103 may include a plurality of functional modules. Such as surface manager (surface manager), media library (Media Libraries), three-dimensional graphics processing library (e.g., openGL ES), 2D graphics engine (e.g., SGL), etc.

The surface manager is used for managing the display subsystem and providing fusion of 2D and 3D layers for a plurality of application programs. Media libraries support a variety of commonly used audio, video format playback and recording, still image files, and the like. The media library may support a variety of audio and video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, etc. The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like. The 2D graphics engine is a drawing engine for 2D drawing.

The hardware abstraction layer 104 runs in user space, encapsulates kernel layer drivers, and provides a call interface to upper layers.

The kernel layer 105 is a layer between hardware and software. The kernel layer 105 contains at least a display driver, a camera driver, an audio driver, and a sensor driver.

S201, after the power key is pressed, the pressing signal is triggered and sent to the input management service.

In an embodiment of the present application, the power key may generate a pressing signal when pressed by a user and send the pressing signal to the input management service, and the key code key of the power key is 26.

S202, the input management service generates an input event according to the pressing signal and distributes the input event to the power management service.

In one embodiment of the present application, the input management service includes an event processing center module (EventHub), an input read module (inputread), and an input dispatch module (inputdispatch). The event processing center module is used for monitoring input operation received by hardware equipment of the electronic equipment. The input reading module is used for acquiring input operation from the event processing center module, analyzing and processing the input operation, generating an input event which can be identified by the application program or the service, and facilitating the response of the application program or the service to the input event. The input distribution module is used for distributing the input event to the corresponding processing window.

In an embodiment of the present application, the event processing center module receives a pressing signal triggered by a power key pressing, and the input reading module is configured to obtain the pressing signal from the event processing center module, analyze and process the pressing signal, generate an input event identifiable by an application program or a service, and facilitate the application program or the service to respond to the input event. Specifically, the input reading module judges whether the display screen is in a bright screen state or a screen-off state currently, if the display screen is in the bright screen state currently, the input event corresponding to the pressing signal is determined to be the control of the display screen to stop the screen, and if the display screen is in the screen-off state currently, the input event corresponding to the pressing signal is determined to be the control of the display screen to stop the screen. The input distribution module is used for distributing the input event to the power management service, and controlling the display screen to be turned off or turned on through the power management service.

S203, the power management service informs the AOD management service to turn off or turn on.

In an embodiment of the present application, if the input event is to control the display screen to be turned off, the power management service invokes the first interface to send an off-screen notification instruction to the AOD management service, so as to notify the AOD management service to turn off the screen.

At this time, the first power-up command CMD 22 corresponds to the first power-down command CMD 21, and may normally control power-up of the display.

When the screen is turned off, if the AOD function is available and the fingerprint unlocking function is unavailable, the power-on instruction is a first power-on instruction CMD 21, and under normal conditions, when the screen is turned on, the AOD function is still available, the fingerprint unlocking function is still unavailable, and the power-on instruction is a first power-on instruction CMD 22 corresponding to the first power-on instruction CMD 21; under abnormal conditions, the electronic equipment enters a power saving mode due to the fact that the electric quantity is too low, when the electronic equipment is in a screen-lighting mode, the AOD function is changed to be unavailable, the fingerprint unlocking function is still unavailable, and the power-on command is still a first power-on command CMD 22 corresponding to the first power-off command CMD 21. At this time, the first power-up command CMD 22 may control power-up of the display.

When the screen is turned off, if the AOD function is unavailable and the fingerprint unlocking function is available, the power-on instruction is a first power-on instruction CMD 21, and when the screen is turned on under normal conditions, the AOD function is still unavailable and the fingerprint unlocking function is still available, and the power-on instruction is a first power-on instruction CMD 22 corresponding to the first power-on instruction CMD 21; under the abnormal condition, the electronic equipment exits from the power saving mode due to the increase of the electric quantity, when the electronic equipment is on a screen, the AOD function is changed to be available, the fingerprint unlocking function is still available, and the power-on instruction is a first power-on instruction CMD 22 corresponding to the first power-off instruction CMD 21. At this time, the first power-up command CMD 22 corresponds to the first power-down command CMD 21, and may normally control power-up of the display.

When the screen is turned off, if the AOD function and the fingerprint unlocking function are not available, the power-down instruction is a second power-down instruction CMD 20, and under normal conditions, when the screen is turned on, the AOD function and the fingerprint unlocking function are not available, and the power-up instruction is a second power-up instruction CMD 20 corresponding to the second power-down instruction CMD 20; under abnormal conditions, the electronic equipment exits from the power saving mode due to the increase of electric quantity, when the electronic equipment is on a screen, the AOD function is changed to be available, the fingerprint unlocking function is still not available, and the power-on instruction is still a second power-on instruction CMD 20 and corresponds to the second power-off instruction CMD 20. At this time, the second power-up command CMD 20 may control the power-up of the display.

That is, after the display screen generates the power-down instruction to turn off the screen according to the current available states of the AOD function and the fingerprint unlocking function, whether the available states of the AOD function and the fingerprint unlocking function are changed or not is not, so that when the display screen is on, a power-up instruction corresponding to the power-down instruction when the display screen is off is generated, and the display screen can be normally controlled to be on.
