The following embodiments and features of the embodiments may be combined with each other without conflict.

For ease of understanding, a description of some of the concepts related to the embodiments of the present application are given by way of example for reference.

Ram IC: the Ram IC is a display driving circuit provided with an independent display memory for driving the display screen to display images, and comprises a compensation memory and a display memory, wherein the compensation memory is used for storing compensation data of uneven display of pictures, and the display memory is used for temporarily storing image data to be displayed.

Ramless IC: the Ramless IC is a display driving circuit without an independent display memory and is used for driving a display screen to display images, the Ramless IC comprises a compensation memory but does not comprise a display memory, and image data to be displayed can be temporarily stored in the compensation memory or directly transmitted to the display screen and is driven to display images.

AOD: the AOD is in an all-day display mode, the electronic equipment can enter the all-day display mode when the screen is turned off, an all-day display area is formed by lighting part of pixel points of the display screen, and important information such as date, time, notification, electric quantity and the like can be continuously displayed in the all-day display area, so that a user can browse the important information under the condition of not turning on the screen.

VDO mode, also called video mode: in one of the picture output modes of the display driving circuit, in the VDO mode, the application processor of the electronic device directly transmits the image data to the display screen for refreshing and displaying the interface through the display driving circuit. In the refreshing display process of the interface, because the image data cannot be stored in the register, the register command in the rendering process of the display interface cannot be stored, and the control command, the control parameter and the like of the refreshing display of the interface are sent to the display screen, the system power consumption in the video mode is higher.

CMD mode, also called command mode: in one of the frame output modes of the display driving circuit, in the CMD mode, the application processor of the electronic device transmits the image data to the storage block of the display driving circuit for buffering, and the display driving circuit transmits the image data to the display screen for displaying. In the refreshing display process of the interface, a register of the storage block can be initialized, and control commands, control parameters and the like of the refreshing display of the interface are stored in the storage block without being sent to a display screen, so that the system power consumption in a command mode is lower than that in a video mode.

Sleep doze mode: also known as a low power consumption mode or a doze mode, the electronic device may enter a sleep state after the screen is removed. In the sleep mode, the system of the electronic device saves power by limiting access to the network and use of the processor by the application, and may also limit synchronization of the application and use of the system alarm clock. Further, in sleep mode, the application whitelist may be set so that some applications may normally use hardware resources and software resources, for example, by the AOD application controlling the display screen to display the AOD area.

For detailed implementation of the display control method, reference is made to the description in the respective embodiments below.

In order to better understand the display control method provided in the embodiment of the present application, an application scenario of the display control method provided in the embodiment of the present application is described below with reference to fig. 1 and fig. 2.

When the Ram IC is adopted as the display screen of the electronic device, in the all-day display mode, the CMD mode is adopted by the display driving circuit to output the picture, the Ram IC includes an independent display memory, and the resolution of the image supported for display is the maximum resolution of the display screen, so that the image can be displayed in a full screen mode, and in the bright screen state and the off screen state, the CMD mode is adopted to output the picture. However, the cost of the display using Ram IC is high, and Ram ICs may be used for the display to reduce the cost. In the bright screen state, the electronic equipment outputs the picture through the VDO mode, in the off screen state, in order to reduce the system power consumption, the Ramless IC display screen of the electronic equipment outputs the picture through the CMD mode, and because the Ramless IC is not provided with an independent display memory, the whole memory is smaller, and the resolution of the image which supports display is also smaller. However, in the full-day display mode, in order to prevent screen burn, the full-day display area needs to be moved on the display screen to perform dynamic display, and under the condition that the resolution of the image supported by the Ramless IC for display is smaller, the full-day display area easily exceeds the designated display range in the moving display process, so that part of the AOD information cannot be continuously displayed, and further, the user cannot intuitively browse part of the AOD information when the display screen is turned off, thereby influencing the use experience of the user.

For example, the resolution of a display screen using a Ramless IC is 2368×1080, and in a bright screen state, the display screen uses a VDO mode to output a picture, and the resolution of a maximum image supported and displayed by the display screen using the Ramless IC is 2368×1080. In the all-day display mode in the off-screen state, the display screen adopts the CMD mode to output pictures, and the resolution of images supported and displayed by the display screen adopting the Ramless IC is smaller than that of the display screen because the memory of the Ramless IC is smaller, for example 1440 x 1080. Referring to fig. 1, in the all-day display mode, the display screen includes an all-day display area and a fingerprint unlocking area, the gray background area in fig. 1 is a display range of the all-day display area, the resolution of the all-day display area is 1240×1080, the display content of the all-day display area includes a screen saver area, a date, a time and an electric quantity, and the resolution of the fingerprint unlocking area is 200×1080. It will be appreciated that the division of the display screen area in fig. 1 is for illustration only, and in other embodiments, the display screen may not be provided with a fingerprint unlocking area in the full day display mode.

In the all-day display mode of the off-screen state, if the position of the all-day display area is kept unchanged, the pixel points of the display screen corresponding to the all-day display area are always in the lighted state, so that the temperature of a part of the area of the display screen is continuously overhigh, and the screen burning is easy to occur. In order to avoid screen burn, the whole day display area can be dynamically moved, and the whole day display area before and after each movement has no overlapping area or only partial overlapping area, so that the same display screen pixel point is ensured not to be continuously lightened. However, because the resolution of the image supported by the display screen adopting the Ramless IC is smaller, the display range corresponding to the whole-day display area is smaller, and the whole-day display area easily exceeds the display range in the moving process, so that part of the area is lost, and the information of the lost part cannot be continuously displayed, thereby influencing the use experience of a user.

Referring to fig. 2, in the off-screen state, when the full-day display area dynamically moves downward and moves beyond the display range corresponding to the full-screen display area, a part of the area is missing, for example, the date, time and electric quantity cannot be displayed normally, so that the user cannot know the date, time and electric quantity of the device in the off-screen state.

In order to solve the problem that a full-day display area of a display screen without an independent memory display driving circuit easily exceeds a designated display range in a mobile display process, so that part of AOD information cannot be continuously displayed, the embodiment of the application provides a display control method and related equipment, which can control the full-day display area to be in mobile display in a display range corresponding to the maximum image resolution supported by the display screen in a full-day display mode, so that the condition that the full-day display information cannot be completely displayed due to the fact that the full-day display area exceeds the designated display range in the mobile display process is avoided. The display control method is applied to electronic equipment, wherein the electronic equipment can be a smart phone, a personal computer, intelligent wearable equipment, an intelligent television and the like.

Referring to fig. 3, 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 framework layer 102 provides an application programming interface (Application Programming Interface, API) and programming framework for application programs of the application layer. The application framework layer includes a number of predefined functions. For example, the application framework layer may include a window manager, a content provider, a view system, a telephony manager, a resource manager, a notification manager, and the like.

Wherein the window manager is used for managing window programs. The window manager can acquire the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like. The content provider is used to store and retrieve data and make such data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebooks, etc. The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, a display interface including a text message notification icon may include a view displaying text and a view displaying a picture. The telephony manager is for providing communication functions of the electronic device. Such as the management of call status (including on, hung-up, etc.). The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like. 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.

For example, the kernel may determine the time an application is operating on a certain portion of hardware.

The kernel layer 105 includes hardware-closely related programs, such as interrupt handlers, device drivers, etc., and basic, common, higher frequency of operation modules, such as clock management modules, process scheduling modules, etc., and critical data structures. The kernel layer may be provided in the processor or cured in an internal memory.

The hardware layer 106 includes hardware of the electronic device, such as a display screen, keys, cameras, etc.

Referring to fig. 4, a flowchart of a display control method according to an embodiment of the present application is shown. The method is applied to the electronic equipment, and the display control method comprises the following steps:

S101, responding to the screen-off instruction, controlling the display screen to be screen-off, and creating an AOD view.

In an embodiment of the present application, if an input event generated after a power key of an electronic device is triggered is detected, an off-screen instruction is generated. If the power key is detected to be pressed and loosened, the power key is determined to be triggered by a user, so that a corresponding input event is generated, and then the display screen is controlled to be turned off in response to the input event. In another embodiment of the present application, the electronic device generates the off-screen instruction when no input event is generated within the second preset time. The second preset time may be an automatic screen locking time of the electronic device set by the user, for example, may be 30 seconds, 1 minute or 2 minutes, which is not limited in the embodiment of the present application. If the electronic device does not generate any input event within the second preset time, it is determined that the electronic device does not receive user operation (such as key operation, touch operation and the like) for a long time, so that power consumption of the system is reduced, electric energy is saved, a screen-killing instruction is automatically generated, and a display screen is controlled to be killed.

In an embodiment of the present application, in response to the power key being triggered, the power management service of the framework layer invokes the backlight setting function to control the backlight of the display screen to power down, turns off the backlight of the display screen, and also invokes the power mode setting function to control the display screen to enter a turned-off state.

In an embodiment of the present application, after the display screen is off and when the AOD function of the electronic device is turned on, the power management service sends an AOD view creation instruction to the AOD application through a screen saver control function (stream Controller), and creates an AOD view through the AOD application.

In an embodiment of the application, the AOD application obtains display information of the AOD region from an application program of the electronic device and creates the AOD view based on the obtained display information. The display information of the AOD area includes, but is not limited to, screen saver images, date, time, power, and latest notification information. For example, a user-selected screen saver image may be obtained at the AOD application, which also obtains the current date from the calendar application, the current time from the clock application, the current power from the power management service, obtains a plurality of notification messages from the application that received the notification messages, and determines the latest notification message from the obtained plurality of notification messages.

In an embodiment of the present application, the number of the horizontal pixels of the AOD area corresponding to the AOD view is smaller than or equal to the number of the horizontal pixels of the preset display range, and the number of the vertical pixels of the AOD area is smaller than or equal to the preset ratio of the number of the vertical pixels of the preset display range, for example, the preset ratio is 50%, that is, the number of the vertical pixels of the AOD area is smaller than or equal to one half of the number of the vertical pixels of the preset display range.

Based on the embodiment, when the timing time of the timer reaches the preset time of the AOD region interval display, the AOD display coordinates are issued from the application layer to the frame layer and then to the hardware layer, so that the AOD region can be timely displayed. In addition, by accumulating the number of failures of setting the display coordinates of the AOD area, a prompt message may be output to prompt the user that the AOD area is displayed abnormally when the number of failures is excessive.

Fig. 14 is a schematic view showing interaction of layers of a software architecture of an electronic device according to another embodiment of the present application.

The input service detects an input event and determines that a power key is triggered; the display screen is turned off; the power management service sends a screen saver starting instruction to the AOD application; the AOD application creates an AOD view; the power management service instructs the AOD application to initialize sleep mode setting; the AOD application sends a dormancy instruction to the power management service; the power management service sends a dormancy switching instruction to the layer composition service; the layer composition service switches the display screen to a dormant state; the layer combination service sends a power mode setting instruction to the display management service; the display management service switches the display screen state into a dormant state; the AOD application determines that the sleep state switching is successful; the AOD is used for calculating the display coordinates of the AOD area after the next movement and transmitting backlight brightness to the power management service; the power management service issues display coordinates and backlight to the display screen; setting backlight of a display screen, displaying an AOD area by the display screen, and entering an AOD mode by the display screen; when the timer reaches 1 minute, calculating the display coordinates of the AOD area after the AOD area moves next time; the AOD application sends the display coordinates of the AOD area after the next movement to the power management service; the power management service transmits the next display coordinates and backlight to the display screen; the display screen sets backlight and next display coordinates; the display screen displays the AOD region. And when the timer reaches 1 minute, calculating the display coordinates of the AOD area after the AOD area moves next time so as to circularly control the AOD area to move and display in the preset display range of the display screen.

Aiming at the problem that the display area is easy to move out of the displayable area in the whole-day display mode of the display screen adopting the Ramless IC, the embodiment of the application can synchronously move the display area along with the AOD view, and the problem of screen burning prevention at present can be solved. In addition, a good communication mechanism is established between the application layer and the bottom layer, so that the frame layer can send instructions to the display screen correctly, and meanwhile, the display screen can respond to and move the displayable area in time. When the AOD application issues backlight, the coordinate position of the next time is transmitted to the display screen through the power management service, the display screen is provided with the backlight, and then the displayable area is moved according to the coordinate of the next time.

After a power key is pressed, the display is turned off, the AOD application creates an AOD view, the power management service is notified to switch the DOZE state, and the power management service notifies the surfaceflinger to switch the DOZE state, and the surfaceflinger controls the display driving circuit and the display to switch to the DOZE mode. The AOD application calculates the next display area of the AOD area, calculates the backlight brightness from the ambient light brightness, and then transmits the calculated backlight brightness to the power management service (the initial display position of the AOD area is stored in advance by the display driving circuit, so that the first display position is not transmitted), and the power management service transmits the backlight command and the position of the next display area to the display driving circuit. Periodically, one minute of backlight command and the position of the next display area are issued. The existing ramless IC can only use a VDO mode, and has higher power consumption. The existing ram IC needs to issue a command to control the movement of an AOD area, does not need to issue coordinates, but needs to wake up the AOD application periodically.
