Description

Screen-off display method and electronic device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on August 29, 2023, with application number 202311103662.7 and application name “A method for screen-off display and electronic device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of electronic devices, and more specifically, to a method for displaying an off-screen display and an electronic device. Background Art

[0003] With the advancement of technology, more and more electronic devices support always on display (AOD), or also known as screen-off display or screen-off display. However, if the screen is not off for a long time, it will easily affect the life of the screen. To solve this problem, electronic devices currently mainly adopt two screen-off display solutions, one is a partial screen-off display solution, and the other is a full-screen screen-off display solution. The partial screen-off display solution has the following shortcomings: (1) It can only display partially, and the electronic device presents less content; (2) Since part of the screen area does not emit light, there will be black areas, and the black areas will produce a sense of abruptness; (3) The electronic device switches the display position at intervals, the visual effect is poor, and the user experience is not good; (4) Since it can only display partially, the screen ages unevenly. The full-screen screen-off display solution displays a fixed picture that does not change. When the electronic device displays the fixed picture, the brightness of each area of ​​the screen is different. If the fixed picture is displayed for a long time, it will also cause uneven screen aging. Therefore, how to avoid uneven screen aging when the screen is off has become an urgent problem to be solved.

[0004] Summary of the Invention

[0005] The present application provides a method for screen-off display and an electronic device, which can perform color processing on pictures in a picture group, and then adjust the display order when the screen is off according to the color of the pictures, thereby ensuring balanced aging of the screen and effectively avoiding the risk of screen burn-in, which can not only improve the user experience but also extend the service life of the screen.

[0006] In a first aspect, a method for screen-off display is provided, which is applied to an electronic device, and the method includes: obtaining a first picture group, the first picture group including multiple pictures; performing color processing on at least one picture in the first picture group with a first parameter to determine a second picture group; wherein the first parameter includes a first reduction coefficient corresponding to the color processing; determining a first display order according to the color parameters of the second picture group, wherein the color parameters include one or more of brightness, contrast, and saturation; when the screen is off, displaying the multiple pictures of the second picture group according to the first display order.

[0007] In an embodiment of the present application, the electronic device can perform color processing on the images in the image group and then adjust the display order of the images during screen-off display based on the colors of the images. The electronic device ensures even screen aging and effectively avoids the risk of screen burn-in, thereby improving the user experience and extending the life of the screen.

[0008] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: determining the display duration of each picture in the second picture group based on the color parameters of each picture in the second picture group; and displaying multiple pictures of the second picture group according to the first display order when the screen is off, including: displaying multiple pictures of the second picture group according to the first display order and the display duration of each picture when the screen is off.

[0009] In an embodiment of the present application, the electronic device can also determine the display time of each picture based on the color of the picture, ensuring balanced aging of the screen and effectively avoiding the risk of screen burn-in, which can not only improve the user experience but also extend the service life of the screen.

[0010] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: determining a first aging progress of each area of ​​the screen based on the second picture group, the first display order and the display duration of each picture; and displaying multiple pictures of the second picture group according to the first display order and the display duration of each picture when the screen is off, including: determining that the first aging progress of each area of ​​the screen meets an aging balance condition, and displaying multiple pictures of the second picture group according to the first display order and the display duration of each picture when the screen is off.

[0011] In an embodiment of the present application, the electronic device can calculate the aging progress of each area of ​​the screen. When the aging progress of each area is balanced and the screen is detected to be off, the second image group can be displayed. The electronic device ensures balanced aging of the screen during screen-off display, effectively avoiding the risk of screen burn-in, improving the user experience and extending the life of the screen.

[0012] In combination with the first aspect, in certain implementations of the first aspect, before performing color processing on at least one picture in the first picture group with a first parameter to determine the second picture group, the method further includes: performing color processing on at least one picture in the first picture group with a second parameter to determine a third picture group, the second parameter being a second reduction coefficient corresponding to the color processing; determining a second display order and a display duration of each picture in the third picture group based on the color parameters of multiple pictures in the third picture group; determining a second aging progress of each area of ​​the screen based on the third picture group, the second display order, and the display duration of each picture in the third picture group; performing color processing on at least one picture in the first picture group with the first parameter to determine the second picture group includes: when it is determined that the second aging progress of each area of ​​the screen does not meet the aging balance condition, performing color processing on at least one picture in the first picture group with the first parameter to determine the second picture group.

[0013] In an embodiment of the present application, the electronic device may first perform color processing on the first image group using the second parameter to determine the third image group. When it is determined that the second aging progress of each area of ​​the screen when displaying the third image group does not meet the aging balance condition, the electronic device may re-perform color processing on the first image group using the first parameter to determine the second image group, so that the aging balance condition is met when displaying the second image group. The electronic device ensures balanced aging of the screen when the screen is off, effectively avoiding the risk of screen burn-in, improving the user experience, and extending the life of the screen.

[0014] Exemplarily, the second parameter may be an initial parameter.

[0015] In combination with the first aspect, in some implementations of the first aspect, the aging balance condition includes: the difference between the first aging progress of any two areas of the screen is less than a first threshold, or the difference between the maximum and minimum values ​​of the first aging progress of each area of ​​the screen is less than a second threshold.

[0016] In combination with the first aspect, in some implementations of the first aspect, the color processing includes one or more of the following: reducing brightness, reducing saturation, and reducing contrast.

[0017] In a second aspect, a method for screen-off display is provided, which is applied to an electronic device, and includes: acquiring a first image; performing color processing on the first image using a first parameter to generate a second image, wherein the first parameter is a first reduction coefficient corresponding to the color processing; determining a first aging progress of each area of ​​the screen based on the second image; determining whether the first aging progress of each area of ​​the screen meets an aging balance condition, and displaying the second image when the screen is off.

[0018] In an embodiment of the present application, the electronic device can perform color processing on the first image to generate a second image. The electronic device then determines whether displaying the second image during screen-off display satisfies an aging balance condition. If the aging balance condition is satisfied, the second image can be displayed during screen-off display. If the aging balance condition is not satisfied, the electronic device can adjust the display again. This ensures screen aging balance and effectively avoids the risk of screen burn-in, improving the user experience and extending the life of the screen.

[0019] In combination with the second aspect, in certain implementations of the second aspect, before performing color processing on the first image with a first parameter to generate a second image, the method also includes: performing color processing on the first image with a second parameter to generate a third image, the second parameter being a second reduction coefficient corresponding to the color processing; determining the second aging progress of each area of ​​the screen based on the third image; performing color processing on the first image with the first parameter to generate the second image, including: determining that the second aging progress of each area of ​​the screen does not meet the aging balance condition, performing color processing on the first image with the first parameter to generate the second image.

[0020] In an embodiment of the present application, the electronic device may first adjust the first image using the second parameter to generate a third image. If the electronic device determines that the aging balance condition is not met when displaying the third image, the electronic device may further adjust the first image using the first parameter to generate a second image. If the electronic device determines that displaying the second image meets the aging balance condition, the electronic device may display the second image when the screen is off, thereby ensuring balanced aging of the screen, effectively avoiding the risk of screen burn-in, and extending the service life of the screen.

[0021] According to a third aspect, a method for screen-off display is provided, which is applied to an electronic device, and the method includes: obtaining a first picture group, which includes multiple pictures; determining color parameters of the first picture group; determining a display order and a corresponding display brightness of each picture in the first picture group according to the color parameters of the first picture group; wherein each picture includes multiple areas, and the display brightness of at least two areas is different; when the screen is off, displaying the multiple pictures of the first picture group according to the display order and the display brightness corresponding to each picture, wherein the display brightness corresponding to each picture is less than the brightness after the electronic device is unlocked.

[0022] In the embodiment of the present application, the electronic device can determine the display order and the display brightness corresponding to each image in the first image group based on the color, thereby displaying the first image group according to the display order and the display brightness corresponding to each image. The electronic device ensures uniform screen aging and can effectively avoid the risk of screen burn-in, thereby improving the user experience and extending the life of the screen.

[0023] In combination with the third aspect, in certain implementations of the third aspect, the method further includes: determining the display duration of each picture in the first picture group based on the color parameters of the first picture group; and displaying the first picture group according to the display order and the display brightness corresponding to each picture when the screen is off, including: displaying multiple pictures of the first picture group according to the display order, the display brightness corresponding to each picture and the display duration of each picture when the screen is off.

[0024] In an embodiment of the present application, the electronic device can also determine the display time of each picture based on the color parameters of the picture, ensuring balanced aging of the screen and effectively avoiding the risk of screen burn-in, which can not only improve the user experience but also extend the service life of the screen.

[0025] In combination with the third aspect, in certain implementations of the third aspect, the method further includes: determining a first aging progress of each area of ​​the screen according to the display brightness corresponding to each picture, the display order, the color parameters of the first picture group, and the display time of each picture; when the screen is off, displaying multiple pictures of the first picture group according to the display order, the display brightness corresponding to each picture, and the display time of each picture, including: determining that the first aging progress of each area of ​​the screen meets an aging balance condition, and when the screen is off, displaying multiple pictures of the first picture group according to the display order, the display brightness corresponding to each picture, and the display time of each picture.

[0026] In an embodiment of the present application, the electronic device can calculate the aging progress of each area of ​​the screen. When the aging progress of each area is balanced and the screen is detected to be off, the first image group can be displayed. The electronic device ensures balanced aging of the screen during screen-off display, effectively avoiding the risk of screen burn-in, improving the user experience, and extending the life of the screen.

[0059] It should be understood that the structures illustrated in the embodiments of the present application do not constitute a specific limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 may include more or fewer components than shown, or may combine or separate certain components, or arrange the components differently. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0060] The processor 110 may include one or more processing units. For example, the processor 110 may include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a memory, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU). The different processing units may be independent devices or integrated into one or more processors.

[0061] The controller may be the nerve center and command center of the electronic device 100. The controller may generate an operation control signal according to the instruction operation code and the timing signal to complete the control of fetching and executing instructions.

[0062] Processor 110 may also include a memory for storing instructions and data. In some embodiments, the memory in processor 110 is a cache memory. This memory can store instructions or data that have just been used or are being recycled by processor 110. If processor 110 needs to use the same instruction or data again, it can directly access the memory. This avoids duplicate accesses, reduces processor 110 latency, and thus improves system efficiency.

[0063] In some embodiments, the processor 110 may include one or more interfaces. The interfaces may include an inter-integrated circuit (I2C) interface, an inter-integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver / transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input / output (GPIO) interface, a subscriber identity module (SIM) interface, and / or a universal serial bus (USB) interface.

[0064] The wireless communication function of the electronic device 100 can be implemented through the antenna 1, the antenna 2, the mobile communication module 150, the wireless communication module 160, the modem processor and the baseband processor.

[0065] Antenna 1 and Antenna 2 are used to transmit and receive electromagnetic wave signals. Each antenna in electronic device 100 can be used to cover a single or multiple communication frequency bands. Different antennas can also be reused to improve antenna utilization. For example, antenna 1 can be reused as a diversity antenna for a wireless local area network. In other embodiments, the antennas can be used in conjunction with a tuning switch.

[0066] The mobile communication module 150 can provide solutions for wireless communications including 2G / 3G / 4G / 5G applied to the electronic device 100. The mobile communication module 150 may include at least one filter, a switch, a power amplifier, a low noise amplifier (LNA), etc. The mobile communication module 150 can receive electromagnetic waves from the antenna 1, and filter, amplify, and process the received electromagnetic waves, and transmit them to the modulation and demodulation processor for demodulation. The mobile communication module 150 can also amplify the signal modulated by the modulation and demodulation processor, and convert it into electromagnetic waves for radiation through the antenna 1. In some embodiments, at least some of the functional modules of the mobile communication module 150 can be set in the processor 110. In some embodiments, at least some of the functional modules of the mobile communication module 150 can be set in the same device as at least some of the modules of the processor 110.

[0067] The modem processor may include a modulator and a demodulator. The modulator is used to modulate the low-frequency baseband signal to be transmitted into a medium-high frequency signal. The demodulator is used to demodulate the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to the baseband processor for processing. After being processed by the baseband processor, the low-frequency baseband signal is passed to the application processor. The application processor outputs a sound signal through an audio device (not limited to the speaker 170A, the receiver 170B, etc.) or displays an image or video through the display screen 194. In some embodiments, the modem processor may be an independent device. In other embodiments, the modem processor may be independent of the processor 110 and be set in the same device as the mobile communication module 150 or other functional modules.

[0068] The wireless communication module 160 can provide wireless communication solutions including wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), infrared (IR), etc., which are applied to the electronic device 100. The wireless communication module 160 can be one or more devices that integrate at least one communication processing module. The wireless communication module 160 receives electromagnetic waves via the antenna 2, frequency modulates and filters the electromagnetic wave signals, and sends the processed signals to the processor 110. The wireless communication module 160 can also receive the signal to be sent from the processor 110, frequency modulate it, amplify it, and convert it into electromagnetic waves for radiation through the antenna 2.

[0069] In some embodiments, the antenna 1 of the electronic device 100 is coupled to the mobile communication module 150, and the antenna 2 is coupled to the wireless communication module 160, so that the electronic device 100 can communicate with a network and other devices through wireless communication technologies. The wireless communication technologies may include global system for mobile communications (GSM), general packet radio service (GPRS), code division multiple access (CDMA), wideband code division multiple access (WCDMA), time-division code division multiple access (TD-CDMA), long term evolution (LTE), BT, GNSS, WLAN, NFC, FM, and / or IR technology. The GNSS may include a global positioning system (GPS), a global navigation satellite system (GLONASS), a Beidou navigation satellite system (BDS), a quasi-zenith satellite system (QZSS) and / or a satellite based augmentation system (SBAS).

[0070] Electronic device 100 implements display functionality through a GPU, display screen 194, and an application processor. A GPU is a microprocessor for image processing that connects display screen 194 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. Processor 110 may include one or more GPUs that execute program instructions to generate or modify display information.

[0071] Display screen 194 is used to display images, videos, and the like. Display screen 194 includes a display panel. The display panel can be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a MiniLED, a MicroLED, a Micro-oLed, or a quantum dot light-emitting diode (QLED). In some embodiments, electronic device 100 may include one or N display screens 194, where N is a positive integer greater than one.

[0072] The electronic device 100 can implement a shooting function through an ISP, a camera 193, a video codec, a GPU, a display screen 194, and an application processor.

[0073] The ISP processes data fed back by camera 193. For example, when taking a photo, the shutter is opened, and light is transmitted through the lens to the camera's photosensitive element. The light signal is converted into an electrical signal, which is then passed to the ISP for processing and converted into a visible image. The ISP can also perform algorithmic optimization on image noise, brightness, and skin tone. It can also optimize parameters such as exposure and color temperature of the captured scene. In some embodiments, the ISP can be located within camera 193.

[0074] The camera 193 is used to capture still images or videos. The object generates an optical image through the lens and projects it onto the photosensitive element. The photosensitive element can be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the light signal into an electrical signal, and then passes the electrical signal to the ISP for conversion into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV or other format. In some embodiments, the electronic device 100 may include 1 or N cameras 193, where N is a positive integer greater than 1.

[0075] The digital signal processor is used to process digital signals. In addition to processing digital image signals, it can also process other digital signals. For example, when the electronic device 100 selects a frequency point, the digital signal processor is used to perform Fourier transform on the frequency point energy.

[0076] Video codecs are used to compress or decompress digital video. Electronic device 100 may support one or more video codecs. This allows electronic device 100 to play or record videos in various encoding formats, such as Moving Picture Experts Group (MPEG) 1, MPEG2, MPEG3, and MPEG4.

[0077] The NPU is a neural network (NN) computing processor. Drawing on the structure of biological neural networks, such as the transmission patterns between neurons in the human brain, it rapidly processes input information and can continuously self-learn. The NPU can enable intelligent cognitive applications in electronic device 100, such as image recognition, face recognition, speech recognition, and text comprehension.

[0078] The external memory interface 120 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the electronic device 100. The external memory card communicates with the processor 110 via the external memory interface 120 to implement data storage functions. For example, files such as music and videos can be stored on the external memory card.

[0079] The internal memory 121 can be used to store computer executable program codes, which include instructions. The processor 110 executes various functional applications and data processing of the electronic device 100 by running the instructions stored in the internal memory 121. The internal memory 121 may include a program storage area and a data storage area. Among them, the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc. The data storage area can store data created during the use of the electronic device 100 (such as audio data, a phone book, etc.), etc. In addition, the internal memory 121 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, a universal flash storage (UFS), etc.

[0080] The electronic device 100 can implement audio functions such as music playback and recording through the audio module 170, the speaker 170A, the receiver 170B, the microphone 170C, the headphone jack 170D, and the application processor.

[0081] The audio module 170 is used to convert digital audio information into analog audio signal output, and is also used to convert analog audio input into digital audio signals. The audio module 170 can also be used to encode and decode audio signals. In some embodiments, the audio module 170 can be provided in the processor 110, or some functional modules of the audio module 170 can be provided in the processor 110.

[0082] The speaker 170A, also called a "speaker", is used to convert audio electrical signals into sound signals. The electronic device 100 can listen to music or listen to hands-free calls through the speaker 170A.

[0083] The receiver 170B, also called a "handset", is used to convert audio electrical signals into sound signals. When the electronic device 100 receives a call or a voice message, the user can place the receiver 170B close to the ear to hear the voice.

[0084] Microphone 170C, also known as "microphone" or "microphone", is used to convert sound signals into electrical signals. When making a call or sending a voice message, the user can speak by putting their mouth close to the microphone 170C to input the sound signal into the microphone 170C. The electronic device 100 can be provided with at least one microphone 170C. In other embodiments, the electronic device 100 can be provided with two microphones 170C, which can not only collect sound signals but also realize noise reduction function. In other embodiments, the electronic device 100 can also be provided with three, four or more microphones 170C to collect sound signals, reduce noise, identify the source of sound, realize directional recording function, etc.

[0085] The pressure sensor 180A is used to sense pressure signals and convert them into electrical signals. In some embodiments, the pressure sensor 180A can be set on the display screen 194. There are many types of pressure sensors 180A, such as resistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, etc. A capacitive pressure sensor can be a device comprising at least two parallel plates with conductive materials. When a force acts on the pressure sensor 180A, the capacitance between the electrodes changes. The electronic device 100 determines the intensity of the pressure based on the change in capacitance. When a touch operation acts on the display screen 194, the electronic device 100 detects the intensity of the touch operation based on the pressure sensor 180A. The electronic device 100 can also calculate the position of the touch based on the detection signal of the pressure sensor 180A. In some embodiments, touch operations acting on the same touch position but with different touch operation intensities can correspond to different operation instructions. For example, when a touch operation with a touch operation intensity greater than or equal to the first pressure threshold acts on the alarm application icon, the instruction to create a new alarm is executed.

[0086] Fingerprint sensor 180H is used to collect fingerprints. Electronic device 100 can use the collected fingerprint characteristics to implement fingerprint unlocking, accessing application locks, taking photos with fingerprints, answering calls with fingerprints, and so on. For example, when the phone detects a user's touch operation on the lock screen, the phone can collect the user's fingerprint information through fingerprint sensor 180H and match the collected fingerprint information with the fingerprint information pre-set in the phone. If the match is successful, the phone can enter the non-lock screen interface from the lock screen interface.

[0087] The touch sensor 180K is also called a "touch panel." The touch sensor 180K can be disposed on the display screen 194. The touch sensor 180K and the display screen 194 form a touch screen, also called a "touch screen." The touch sensor 180K is used to detect touch operations applied thereto or in the vicinity thereof. The touch sensor can transmit the detected touch operations to the application processor to determine the type of touch event. Visual output related to the touch operations can be provided via the display screen 194. In other embodiments, the touch sensor 180K can also be disposed on the surface of the electronic device 100, in a location different from that of the display screen 194.

[0088] Figure 2 is a software structure diagram of the electronic device 100 according to an embodiment of the present application. The layered architecture divides the software into several layers, each with clear roles and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, namely, the application layer, the application framework layer, the Android runtime (Android runtime) and the system library, and the kernel layer, from top to bottom. The application layer can include a series of application packages.

[0089] As shown in Figure 2, the application layer may include camera, settings, third-party applications, etc. Among them, the third-party applications may include gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message, etc.

[0090] The application framework layer provides an application programming interface (API) and a programming framework for applications in the application layer. The application framework layer may include some predefined functions.

[0091] As shown in FIG2 , 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.

[0092] The window manager manages windowed applications. It can determine the display size, determine whether a status bar is present, lock the screen, and take screenshots. Content providers store and retrieve data and make it accessible to applications. This data can include video, images, audio, incoming and outgoing calls, browsing history and bookmarks, and phone books.

[0093] The view system includes visual controls, such as controls for displaying text and images, such as the instructions for prompting a virtual shutter button in the embodiments of this application. The view system can be used to build applications. A display interface can be composed of one or more views. For example, a display interface including a text notification icon can include a view for displaying text and a view for displaying images.

[0094] The phone manager is used to provide communication functions of the electronic device 100, such as management of call status (including answering, hanging up, etc.).

[0095] The resource manager provides various resources for applications, such as localized strings, icons, images, layout files, video files, and so on.

[0096] The Notification Manager allows applications to display notifications in the status bar. These messages can be displayed briefly and then disappear automatically without user interaction. For example, the Notification Manager is used to notify users of completed downloads and message reminders. The Notification Manager can also display notifications in the top status bar of the system as icons or scrolling text, such as notifications from background applications, or as dialog windows on the screen. Examples include text messages in the status bar, beeps, vibrations on electronic devices, and flashing indicator lights.

[0097] The Android runtime includes the core library and the virtual machine. The Android runtime is responsible for scheduling and management of the Android system.

[0098] The core library consists of two parts: one is the function that needs to be called by the Java language, and the other is the Android core library.

[0099] The application layer and application framework layer run in a virtual machine. The virtual machine executes Java files in the application layer and application framework layer as binary files. The virtual machine manages object lifecycles, stack management, thread management, security and exception management, and garbage collection.

[0100] The system library can include multiple functional modules, such as a surface manager, media libraries, a 3D graphics processing library (such as OpenGL ES), and a 2D graphics engine (such as SGL).

[0101] The surface manager is used to manage the display subsystem and provide fusion of 2D and 3D layers for multiple applications.

[0102] The media library supports playback and recording of a variety of common audio and video formats, as well as static image files. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0103] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

[0104] A 2D graphics engine is a drawing engine for 2D drawings.

[0105] In addition, the system library can also include status monitoring service modules, such as a physical status recognition module for analyzing and identifying user gestures; a sensor service module for monitoring sensor data uploaded by various sensors at the hardware layer to determine the physical status of the electronic device 100.

[0106] The kernel layer is the layer between hardware and software. The kernel layer includes at least display driver, camera driver, audio driver, and sensor driver.

[0107] The hardware layer may include various sensors, such as the various sensors introduced in FIG. 1 , the acceleration sensor, gyroscope sensor, touch sensor, etc. involved in the embodiments of the present application.

[0108] With technological advancements, more and more electronic devices support AOD. However, leaving the screen on for extended periods can easily shorten its lifespan. For example, the screen's light-emitting devices (such as light-emitting diodes) can rapidly age due to frequent emission of light in certain frequency bands, resulting in the formation of dead pixels on the screen. To address this issue, electronic devices currently employ two main screen-off display solutions: partial screen-off display and full-screen screen-off display.

[0109] Partial screen-off display solution: When the screen is off, the electronic device can display a clock and a fixed pattern in a certain area of ​​the screen, while the rest of the screen remains dark. The electronic device can also change the location of the clock and fixed pattern at intervals.

[0110] FIG3 shows a graphical user interface (GUI) of a partial screen-off display solution.

[0111] As shown in (a) and (b) of FIG3 , when the screen is off, the electronic device can display a clock 301 and a pattern 302 at a local position #1 of the screen. After the electronic device displays the clock 301 and the pattern 302 at the local position #1 of the screen for t seconds, the electronic device can display the clock 301 and the pattern 302 at the local position #2 of the screen.

[0112] Based on the above description, it can be seen that the partial screen-off display solution has the following shortcomings: (1) It can only display partially, and the electronic device presents less content; (2) Since some areas of the screen do not emit light, there will be black areas, and the black areas will produce an abrupt feeling; (3) The electronic device switches the display position at intervals, the visual effect is poor, and the user experience is not good; (4) Since it can only display partially, the screen ages unevenly.

[0113] Full-screen off-screen display solution: When the electronic device is off, it can display pictures in full screen, and when displaying pictures in full screen, it can reduce the brightness of the pictures.

[0114] FIG4 shows a GUI of a full-screen screen-off display solution.

[0115] As shown in Figure 4, when the screen is off, the electronic device can display a clock 401 and a picture 402 in full screen. It should be noted that in the current full-screen off-screen display solution, the electronic device will not change the position of the clock 401, nor will it switch the picture 402 to another picture.

[0116] From the above description, it can be seen that the picture displayed by the full-screen off-screen display solution is unchanged. When the electronic device displays the fixed picture, the brightness of each area of ​​the screen is different. If the fixed picture is displayed for a long time, it will also cause uneven aging of the screen.

[0117] In summary, the current partial screen-off display solution and full screen screen-off display solution can cause uneven screen aging, poor display effects, screen burn-in and other problems, which in turn leads to a decline in user experience. Based on this, the embodiments of the present application provide a screen-off display method and an electronic device. The electronic device can perform color processing on the images in the image group, and then adjust the display order when the screen is off according to the color parameters of the images, ensuring balanced screen aging and effectively avoiding the risk of screen burn-in, which can not only improve the user experience but also extend the service life of the screen.

[0118] For ease of understanding, a schematic diagram of the system framework provided by an embodiment of the present application is shown in Figure 5. As shown in Figure 5, the system framework in the embodiment of the present application includes an image processing module and an image arrangement module.

[0119] The image processing module is used to perform color processing on the image. The color processing in the embodiment of the present application includes but is not limited to: reducing brightness and reducing saturation.

[0120] The picture arrangement module is used to arrange the display order of pictures when the electronic device is on screen.

[0121] In some embodiments, the picture arrangement module is further used to determine the display duration of each picture when the electronic device is on screen off.

[0122] In some embodiments, the picture arrangement module is further used to determine the aging progress of the screen according to the display order of the pictures and the display duration of each picture.

[0123] In some embodiments, the picture arrangement module is further used to communicate with the picture processing module when it is determined that the aging progress does not meet the aging balance condition, so that the picture processing module re-processes the color of the picture, and then the picture arrangement module readjusts the display order of the pictures and the display duration of each picture.

[0124] The image processing module and image arrangement module shown in FIG5 may be modules of the application layer, or may be modules of the application framework layer, which is not limited in this embodiment of the present application.

[0125] FIG6 shows a schematic flow chart of a method 600 for displaying an off-screen display according to an embodiment of the present application. The method is applied to an electronic device. As shown in FIG6 , the method 600 includes:

[0126] S601: Obtain a first picture group.

[0127] In the embodiment of the present application, there is no limitation on the manner in which the electronic device obtains the first picture group. Several possible implementation methods are exemplarily introduced below.

[0128] A possible implementation manner: the electronic device obtains the first picture group in response to the user selecting at least two pictures in the photo album.

[0129] A possible implementation manner: In response to a user selecting a first theme, the electronic device obtains a first picture group associated with the first theme.

[0130] A possible implementation method: the electronic device includes a screen-off display gallery, and the pictures in the screen-off display gallery can be uploaded by the user and / or preset by the system. The electronic device obtains the first picture group in response to the user selecting a picture in the screen-off display gallery.

[0131] A possible implementation method: the server corresponding to the electronic device includes a screen-off display gallery, and the electronic device can communicate with the server to obtain the first picture group.

[0132] S602: Perform color processing on at least one picture in the first picture group using a first parameter to determine a second picture group.

[0133] In some embodiments, after obtaining the first picture group, the electronic device may perform color processing on all pictures in the first picture group using the first parameter. In these embodiments, the second picture group includes all color-processed pictures in the first picture group, i.e., the number of pictures in the first picture group is the same as the number of pictures in the second picture group.

[0134] For example, the first picture group includes three pictures, and the electronic device can perform color processing on the three pictures according to the first parameter, and the second picture group includes the three pictures after color processing.

[0135] In some embodiments, after obtaining the first picture group, the electronic device may perform color processing on some of the pictures in the first picture group using the first parameter. In these embodiments, the second picture group includes both all pictures in the first picture group that have undergone color processing and all pictures in the first picture group that have not undergone color processing, i.e., the number of pictures in the first picture group is the same as the number of pictures in the second picture group.

[0136] For example, the first picture group includes three pictures, namely picture #1, picture #2 and picture #3. The electronic device can perform color processing on picture #1 and picture #2 with the first parameter and does not perform color processing on picture #3. Then the second picture group includes picture #1 and picture #2 that have been color processed and picture #3 that has not been color processed.

[0137] In some embodiments, the electronic device includes a storage path of the AOD picture group, and the electronic device can store the second picture group according to the storage path.

[0138] The color processing in the embodiments of the present application includes but is not limited to reducing brightness, reducing saturation, and reducing contrast.

[0139] When an electronic device performs color processing on a picture, it can perform one color processing on the picture or multiple color processing on the picture.

[0140] For example, the first picture group includes picture #1, picture #2 and picture #3, where the electronic device reduces the brightness of picture #1, reduces the brightness and saturation of picture #2, and reduces the brightness, saturation and contrast of picture #3.

[0141] The electronic device performs color processing on the image using a first parameter, where the first parameter can be understood as a reduction coefficient corresponding to the color processing.

[0142] For example, the electronic device performs brightness reduction processing on picture #1, and the first parameter includes a brightness reduction coefficient (for example, the brightness reduction coefficient is 20%).

[0143] For another example, the electronic device performs brightness reduction processing and saturation reduction processing on picture #2, and the first parameter includes reducing the brightness coefficient (for example, reducing the brightness coefficient to 20%) and reducing the saturation coefficient (for example, reducing the saturation coefficient to 30%).

[0144] The first parameter may be an initial parameter, may be preset by the system, or may be set by the user.

[0145] In order to more clearly introduce the color processing in the embodiment of the present application, it will be introduced in conjunction with Figure 7 below. It should be noted that for the sake of convenience, when introducing color processing below, the color processing is taken as reducing brightness as an example, but it should not be understood as a specific limitation on the color processing of the embodiment of the present application.

[0146] As shown in (a) in Figure 7, the first picture group includes picture #1 and picture #2, where the brightness value of the upper half of picture #1 is brightness value #1, and the brightness value of the lower half is brightness value #2, the brightness value of the upper half of picture #2 is brightness value #2, and the brightness value of the lower half is brightness value #1, and brightness value #1 is greater than brightness value #2. After brightness reduction processing, the brightness value of the upper half of picture #1 becomes brightness value #3, and the brightness value of the lower half becomes brightness value #4, the brightness value of the upper half of picture #2 becomes brightness value #4, and the brightness value of the lower half becomes brightness value #3, where brightness value #1 is greater than brightness value #2, brightness value #2 is greater than brightness value #3, and brightness value #3 is greater than brightness value #4.

[0147] It can be understood that, in the example shown in (a) of FIG. 7 , the second picture group includes picture # 1 processed with reduced brightness and picture # 2 processed with reduced brightness.

[0148] As shown in (b) in Figure 7, the first picture group includes picture #1, picture #2 and picture #3, where the brightness value of the upper half of picture #1 is brightness value #1, and the brightness value of the lower half is brightness value #2, the brightness value of the upper half of picture #2 is brightness value #2, and the brightness value of the lower half is brightness value #1, brightness value #1 is greater than brightness value #2, and the brightness of picture #3 is brightness value #3. The electronic device can reduce the brightness of picture #1 and picture #2. After the brightness reduction processing, the brightness value of the upper half of picture #1 becomes brightness value #3, and the brightness value of the lower half becomes brightness value #4, the brightness value of the upper half of picture #2 becomes brightness value #4, and the brightness value of the lower half becomes brightness value #3.

[0149] It can be understood that, in the example shown in (b) of FIG. 7 , the second picture group includes picture #1 processed with reduced brightness, picture #2 processed with reduced brightness, and picture #3 not processed with reduced brightness.

[0150] S603: Determine a first display order according to color parameters of the multiple pictures in the second picture group.

[0151] After the electronic device determines the second picture group, it can determine the first display order according to the color parameters of each picture in the second picture group to ensure balanced display. The color parameters include but are not limited to brightness, contrast, and saturation.

[0152] FIG8 shows a schematic diagram of determining a first display order according to color parameters of a second picture group provided by an embodiment of the present application.

[0153] As shown in Figure 8, the second picture group includes picture #1 and picture #2. The brightness value of the upper half of picture #1 is brightness value #3, and the brightness value of the lower half is brightness value #4. The brightness value of the upper half of picture #2 is brightness value #4, and the brightness value of the lower half is brightness value #3. The first display order determined by the electronic device can be to display picture #1 first and then display picture #2 and so on, where brightness value #3 is greater than brightness value #4.

[0154] FIG9 shows another schematic diagram of determining the first display order according to the color parameters of the second picture group provided by an embodiment of the present application.

[0155] As shown in Figure 9, the second picture group includes picture #1, picture #2 and picture #3. The brightness value of the upper half of picture #1 is brightness value #3, and the brightness of the lower half is changed to brightness value #4. The brightness value of the upper half of picture #2 is brightness value #4, and the brightness value of the lower half is brightness value #3. The brightness of picture #3 is brightness #3. The first display order determined by the electronic device can be to display picture #3 first, then display picture #1, then display picture #2 and repeat this cycle, where brightness value #3 is greater than brightness value #4.

[0156] FIG10 shows another schematic diagram of determining the first display order according to the color parameters of the second picture group provided by an embodiment of the present application.

[0157] As shown in Figure 10, the second picture group includes picture #1, picture #2, picture #3 and picture #4, the brightness value of the upper half of picture #1 is brightness value #3, and the brightness value of the lower half is brightness value #4, the brightness value of the upper half of picture #2 is brightness value #3, and the brightness value of the lower half is brightness value #4, the brightness value of the upper half of picture #3 is brightness value #4, and the brightness value of the lower half is brightness value #3, the brightness value of the upper half of picture #4 is brightness value #4, and the brightness value of the lower half is brightness value #3, the first display order determined by the electronic device can be to display picture #1 first, then display picture #3, then display picture #2, then display picture #4 and so on, where brightness value #3 is greater than brightness value #4.

[0158] From the above description, it can be seen that the electronic device can adjust the display order of the second picture group so that pictures with different color parameters are displayed alternately, thereby ensuring balanced aging of the screen of the electronic device when the screen is off.

[0159] S604: When the screen is off, display the plurality of pictures of the second picture group according to the first display order.

[0160] When the electronic device detects that the screen is off, it can display multiple pictures of the second picture group in the first display order.

[0161] In an embodiment of the present application, the electronic device can perform color processing on the images in the image group and then adjust the display order of the images during screen-off display based on the colors of the images. The method provided by the implementation of this application ensures balanced screen aging and can effectively avoid the risk of screen burn-in, thereby improving the user experience and extending the life of the screen.

[0162] In some embodiments of the present application, the display duration of each picture in the second picture group may be preset by the system or may be set by the user.

[0163] For example, each picture is displayed for 2 minutes at a time.

[0164] In some other embodiments of the present application, the display duration of each image is determined according to color parameters. As shown in FIG11 , the method 600 further includes:

[0165] S605 : Determine the display duration of each picture in the second picture group according to the color parameter of each picture.

[0166] In addition to determining the display order, the electronic device may also determine the display duration of each picture in the second picture group.

[0167] For example, as shown in Figure 8, the electronic device can determine that the display time of picture #1 and picture #2 is 2 minutes each time, that is, after the electronic device displays picture #1 for 2 minutes, it switches picture #1 to picture #2, and after the display time of picture #2 reaches 2 minutes, it switches to picture #1.

[0168] For another example, FIG12 shows a schematic diagram of determining the display duration of each picture in the second picture group according to the color parameters of the second picture group, provided by an embodiment of the present application.

[0169] As shown in FIG12 , the second picture group includes picture #1, picture #2, and picture #3. The brightness value of the upper half of picture #1 is brightness value #3, and the brightness value of the lower half is brightness value #4. The brightness value of the upper half of picture #2 is brightness value #3, and the brightness value of the lower half is brightness value #4. The brightness value of the upper half of picture #3 is brightness value #4, and the brightness value of the lower half is brightness value #3. The electronic device determines the display order to first display picture #1, then picture #2, and then picture #3, and so on. Since the brightness value of the upper half of picture #1 and picture #2 is brightness value #3, and the brightness value of the lower half is brightness value #4, while the brightness value of the upper half of picture #3 is brightness value #4, and the brightness value of the lower half is brightness value #3, in order to ensure balanced aging of the screen, the duration of each display of picture #3 can be greater than the duration of each display of picture #1 and picture #2. For example, the duration of each display of picture #1 and picture #2 is 2 minutes, and the duration of each display of picture #3 is 4 minutes, wherein the brightness value #3 is greater than the brightness value #4.

[0170] It should be noted that there is no actual order in which step S603 and step S605 are executed. The electronic device may execute step S603 first and then step S605, or may execute step S605 first and then step S603, or may execute step S603 and step S605 simultaneously.

[0171] With reference to FIG11 , in some embodiments, displaying multiple pictures of the second picture group according to the first display order when the screen is off may include:

[0172] S6041: When the screen is off, display multiple pictures of the second picture group according to the first display order and the display duration of each picture.

[0173] In an embodiment of the present application, the electronic device can also determine the display time of each picture based on the color of the picture, ensuring balanced aging of the screen and effectively avoiding the risk of screen burn-in, which can not only improve the user experience but also extend the service life of the screen.

[0174] To ensure even aging of the screen, the electronic device may further calculate the aging progress of the screen. As shown in FIG13 , the method 600 further includes:

[0175] S606: Determine a first aging progress of each area of ​​the screen according to the second picture group, the first display order, and the display duration of each picture.

[0176] After the electronic device determines the display order of the second picture group and the display time of each picture, it determines the display brightness of each area of ​​the screen of the electronic device when displaying the second picture group and the working status of the pixels in each area of ​​the screen. Since the aging progress of the screen is related to the display brightness and pixel aging speed of the screen, the second electronic device can determine the first aging progress of each area of ​​the screen based on the second picture group, the first display order and the display time of each picture in the second picture.

[0177] It should be noted that the present embodiment of the present application does not limit the method for determining the screen aging progress based on the screen's display brightness and pixel aging speed. In other words, in the present embodiment of the present application, a function expression can be established with the screen's display brightness and pixel aging speed as the independent variables and the screen aging progress as the dependent variable. In this function expression, the independent variables and the dependent variable are positively correlated, but the specific form of this function expression is not limited.

[0178] 11 , in some embodiments, displaying multiple pictures of the second picture group according to the first display order and the display duration of each picture in the second picture group during screen off display may include:

[0179] S6042: Determine whether the first aging progress of each area of ​​the screen satisfies an aging balance condition, and display multiple pictures of the second picture group according to the first display order and the display duration of each picture during screen off display.

[0180] After determining the first aging progress of each region, the electronic device may determine whether the first aging progress of each region satisfies an aging balance condition. If it is determined that the first aging progress of each region of the screen satisfies the aging balance condition, the electronic device may display the second image group during screen-off display according to the first display order and the display duration of each image in the second image group.

[0181] In the embodiments of the present application, there is no specific limitation on the aging equalization conditions. The following is an illustrative introduction to several aging equalization conditions that can be applied to various methods.

[0182] Exemplarily, the aging balance condition is: a first aging progress difference between any two areas of the screen is less than a first threshold.

[0183] For example, taking the second picture group as the picture group shown in Figure 8 as an example, the electronic device determines that the first aging progress of the upper half of the screen is aging progress value #1, the first aging progress of the lower half is aging progress value #2, and the difference between the aging progress value #1 and the aging progress value #2 is less than the first threshold, which indicates that the aging of the screen is balanced. Therefore, the electronic device can display the second picture group according to the first display order and the display time of each picture in the second picture group when the screen is off.

[0184] Exemplarily, the aging balance condition is: the difference between the maximum value and the minimum value in the first aging progress of each area of ​​the screen is less than a second threshold.

[0185] For example, the electronic device divides the screen into three parts, the first aging progress value of the first part is aging progress value #1, the first aging progress value of the second part is aging progress value #2, and the first aging progress value of the third part is aging progress value #3, and the aging progress value #1 is greater than the aging progress value #2, and the aging progress value #2 is greater than the aging progress value #3. When the difference between the aging progress value #1 and the aging progress value #3 is less than the second threshold, it indicates that the aging of the screen is balanced. Therefore, the electronic device can display the second picture group according to the first display order and the display time of each picture in the second picture group when the screen is off.

[0186] The first threshold may be equal to the second threshold, or may not be equal to the second threshold.

[0187] It should be understood that the above two aging balance conditions are only examples. In the embodiment of the present application, the aging balance condition can also be determined by other calculation methods. For example, the aging balance condition is that the variance of the first aging progress of each area of ​​the screen is less than the third threshold.

[0188] In an embodiment of the present application, the electronic device can calculate the aging progress of each area of ​​the screen. When the aging progress of each area is balanced and the screen is detected to be off, the electronic device can display multiple images from the second image group. This ensures balanced aging of the screen during the off-screen display, effectively avoiding the risk of screen burn-in and extending the screen's service life.

[0189] In some embodiments, as shown in FIG14 , before performing color processing on at least one picture in the first picture group using the first parameter to determine the second picture group, the method 600 further includes:

[0190] S607 : Perform color processing on at least one picture in the first picture group using the second parameter to determine a third picture group.

[0191] S608 : Determine a second display order and a display duration of each picture in the third picture group according to color parameters of the multiple pictures in the third picture group.

[0192] S609 : Determine a second aging progress of each area of ​​the screen according to the third picture group, the second display order, and the display duration of each picture in the third picture group.

[0193] It should be understood that the description of steps S607 to S609 can be found above and will not be repeated here.

[0194] 14 , in some embodiments, performing color processing on at least one picture in the first picture group using a first parameter to determine the second picture group may include:

[0195] S6021: When it is determined that the second aging progress of each area of ​​the screen does not meet the aging balance condition, perform color processing on at least one picture in the first picture group using the first parameter to determine a second picture group.

[0196] For example, in the case of color processing involving brightness reduction, the first and second parameters represent brightness reduction coefficients, with the first parameter value being 40% and the second parameter value being 30%. The first image group includes images #1 and #2, and brightness reduction processing is performed on images #1 and #2 using the second parameter to generate images #3 and #4, respectively. Because the electronic device fails to meet the aging equalization condition when displaying images #3 and #4 on the off screen, the electronic device may further reduce the brightness of images #1 and #2 using the first parameter to generate images #5 and #6, respectively.

[0197] In some embodiments, the second parameter may be a preset initial parameter.

[0198] FIG15 shows a comparative schematic diagram of color processing of a first picture group using a first parameter and a second parameter provided in an embodiment of the present application.

[0199] As shown in (a) of FIG15 , a first picture group includes picture #1 and picture #2, wherein the brightness value of the upper half of picture #1 is brightness value #1, the brightness value of the lower half is brightness value #2, and the brightness value of picture #2 is brightness value #1. The electronic device performs brightness reduction processing on picture #1 and picture #2 using a second parameter. After the brightness reduction processing, the brightness value of the upper half of picture #1 is changed to brightness value #3, the brightness value of the lower half is changed to brightness value #4, and the brightness value of picture #2 is changed to brightness value #3, wherein brightness value #1 is greater than brightness value #2, brightness value #2 is greater than brightness value #3, and brightness value #3 is greater than brightness value #4. After determining the third picture group, the electronic device can further determine a second aging progress for the upper and lower halves of the screen. If the second aging progress for the upper and lower halves of the screen does not meet the aging balance condition, the electronic device can re-perform brightness reduction processing on the first picture group using the first parameter.

[0200] As shown in (b) in Figure 15, the electronic device performs brightness reduction processing on picture #1 and picture #2 with the first parameter. After the brightness reduction processing, the brightness value of the upper half of picture #1 becomes brightness value #4, the brightness value of the lower half becomes brightness value #5, and the brightness value of picture #2 becomes brightness value #4, where brightness value #1 is greater than brightness value #2, brightness value #2 is greater than brightness value #3, brightness value #3 is greater than brightness value #4, and brightness value #4 is greater than brightness value #5.

[0201] In some embodiments, as shown in FIG14 , the method 600 further includes:

[0202] S605: Determine a second picture parameter according to the color parameter of each picture in the second picture group and determine the display time of each picture.

[0203] S606: Determine a first aging progress of each area of ​​the screen according to the second picture group, the first display order, and the display duration of each picture.

[0204] 14 , in some embodiments, when the screen is off, displaying multiple pictures of the second picture group according to the first display order may include:

[0205] S6043: Determine whether the first aging progress of each area of ​​the screen satisfies an aging balance condition, and display multiple pictures of the second picture group according to the first display order and the display duration of each picture when the screen is off.

[0206] It should be understood that the description of step S605, step S606 and step S6043 can be found above and will not be repeated here.

[0207] In an embodiment of the present application, the electronic device may first perform color processing on the first image group based on the second parameter to determine the third image group. If it is determined that the second aging progress of each area of ​​the screen does not meet the aging balance condition, the first image group may be color processed again based on the first parameter to determine the second image group. When the electronic device displays the second image group, the aging balance condition is met, ensuring balanced aging of the electronic device's screen when the screen is off, effectively avoiding the risk of screen burn-in and extending the screen's service life.

[0208] In the screen-off display method provided in the embodiment of the present application introduced above, the electronic device can perform color processing on the first picture group so that the electronic device can reduce the brightness when displaying the first picture group on the screen. In other embodiments of the present application, the electronic device may not perform color processing on the first picture group, but adjust the display brightness of the display screen according to the color of the first picture group. This will be described in detail below in conjunction with Figures 16-19.

[0209] FIG16 shows a schematic flow chart of a method 1600 for displaying an off-screen display according to an embodiment of the present application. As shown in FIG16 , the method 1600 includes:

[0210] S1601: Obtain a first picture group.

[0211] It should be understood that the description of step S1601 can be found above, and for the sake of brevity, it will not be repeated here.

[0212] S1602: Determine color parameters of the first picture group.

[0213] After acquiring the first picture group, the electronic device may determine the color parameters of each picture in the first picture group.

[0214] For example, the electronic device may determine the brightness values ​​of various parts of each photo in the first picture group.

[0215] For another example, the electronic device may determine the saturation of each portion of each photo in the first picture group.

[0216] S1603 : Determine a display order and corresponding display brightness of each picture in the first picture group according to the color parameter of the first picture group.

[0217] It should be understood that the description of step S1603 can be found in the above description, and for the sake of brevity, it will not be repeated here.

[0218] S1604 , when the screen is off, display the multiple pictures of the first picture group according to the display order and the display brightness corresponding to each picture in the first picture group.

[0219] The display brightness of the electronic device's screen after it is unlocked is display brightness #1. When the user selects "Screen Off," the electronic device can adjust the screen's display brightness from display brightness #1 to the display brightness corresponding to each image when displaying images in the first image group. The first image group is displayed according to the display order, with the display brightness corresponding to each image in the first image group being lower than the brightness after the electronic device is unlocked. Each image includes multiple regions, and at least two regions have different display brightnesses.

[0220] It is easy to understand that the display brightness corresponding to different color parameters in the first picture group may be different.

[0221] For example, taking the first picture group including picture #1 and picture #2 shown in Figure 15 that have not been processed by brightness reduction as an example, the electronic device can determine the display brightness #1 and display brightness #2 corresponding to picture #1 and picture #2 respectively based on the brightness of picture #1 and picture #2 in Figure 15. Since the overall brightness of picture #1 is less than the overall brightness of picture #2, the display brightness #1 can be greater than the display brightness #2.

[0222] In an embodiment of the present application, the electronic device can determine the display order based on the color parameters of the first image group. When the screen is off, the electronic device can reduce the display brightness based on the color of each image in the first image group and display the first image group according to the display order. This ensures uniform screen aging and effectively avoids the risk of screen burn-in, thereby improving the user experience and extending the life of the screen.

[0223] In some embodiments, as shown in FIG17 , the method 1600 further includes:

[0224] S1605 : Determine a display duration of each picture in the first picture group according to the color parameters of the first picture group.

[0225] 17 , when the screen is off, displaying the first picture group according to the display order and the display brightness corresponding to each picture in the first picture group may include:

[0226] S1606 , when the screen is off, display multiple pictures of the first picture group according to the display order, the display brightness corresponding to each picture in the first picture group, and the display time of each picture in the first picture group.

[0227] It should be understood that the description of step S1605 and step S1606 can be found above, and for the sake of brevity, they will not be repeated here.

[0228] It should be noted that there is no actual order in which steps S1603 and S1605 are executed. The electronic device may execute step S1603 first and then step S1605, or may execute step S1605 first and then step S1603, or may execute step S1603 and step S1605 simultaneously.

[0229] In an embodiment of the present application, the electronic device can also determine the display time of each picture based on the color of the picture, ensuring balanced aging of the screen and effectively avoiding the risk of screen burn-in, which can not only improve the user experience but also extend the service life of the screen.

[0230] In some embodiments, as shown in FIG18 , the method 1600 further includes:

[0231] S1607: Determine a first aging progress of each area of ​​the screen according to the display brightness and display order corresponding to each picture in the first picture group, the color parameters of the first picture group, and the display duration of each picture in the first picture group.

[0232] Different from step S606, in step S1607, the electronic device has determined the display brightness of the screen when displaying each picture in the first picture group. The electronic device can also determine the working status of the pixels in each area of ​​the screen according to the display order, the color of the first picture group and the display time of each picture in the first picture group, and then determine the first aging progress of each area of ​​the screen according to the display brightness and the working status of the pixels in each area of ​​the screen.

[0233] 18 , when the screen is off, displaying multiple pictures of the first picture group according to the display order and the display brightness corresponding to each picture in the first picture group may include:

[0234] S1608, determining whether the first aging progress of each area of ​​the screen meets the aging balance condition, and when the screen is off, displaying multiple pictures of the first picture group according to the display order, the display brightness corresponding to each picture in the first picture group, and the display time of each picture in the first picture group.

[0235] It should be understood that the description of step S1608 can be found above, and for the sake of brevity, it will not be repeated here.

[0236] In an embodiment of the present application, the electronic device can calculate the aging progress of each area of ​​the screen. When the aging progress of each area is balanced and the screen is detected to be off, the electronic device can display the first image group. This ensures balanced aging of the screen during the off-screen display, effectively avoiding the risk of screen burn-in, improving the user experience, and extending the life of the screen.

[0237] In the method of screen-off display described above, the electronic device obtains multiple pictures, but the embodiments of the present application are not limited to this. In other embodiments of the present application, the electronic device may also obtain only one picture, and then perform color processing on the picture and determine whether the aging balance condition is met. When the aging balance condition is met, the color-processed picture can be displayed when the screen is off. This will be introduced in conjunction with Figure 19 below.

[0238] FIG19 shows a schematic flow chart of a method for displaying an off-screen display according to an embodiment of the present application. As shown in FIG19 , the method 1900 includes:

[0239] S1901, obtain the first picture.

[0240] S1902: Perform color processing on the first image using the first parameter to generate a second image.

[0241] It should be understood that for the description of step S1901 and step S1902, please refer to the above text, and for the sake of brevity, they will not be repeated here.

[0242] S1903: Determine a first aging progress of each area of ​​the screen according to the second image.

[0243] After the electronic device generates the second picture, it determines the display brightness of each area of ​​the screen and the working status of the pixels in each area of ​​the screen when the electronic device displays the second picture. Therefore, the electronic device can determine the first aging progress of each area of ​​the screen based on the second picture.

[0244] S1904: Determine whether the first aging progress of each area of ​​the screen meets an aging balance condition, and display the second image when the screen is off.

[0245] It should be understood that for the description of step S1904, please refer to the above text, and for the sake of brevity, it will not be repeated here.

[0247] S1905: Perform color processing on the first image using the second parameter to generate a third image.

[0248] S1906: Determine a second aging progress of each area of ​​the screen according to the third image.

[0250] S1907: Determine that the second aging progress of each area of ​​the screen does not meet the aging balance condition, and perform color processing on the first image using the first parameter.

[0251] It should be understood that for the description of steps S1905 to S1907, please refer to the above text, and for the sake of brevity, they will not be repeated here.

[0252] In this embodiment of the present application, the electronic device can first perform color processing on the first image to generate a third image, and then determine whether the third image displayed when the screen is off meets the aging balance condition. If the aging balance condition is not met, further adjustments can be made, thereby ensuring the aging balance of the screen, effectively avoiding the risk of screen burn-in, improving the user experience, and extending the life of the screen.
