[0041] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0042] In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0043] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this embodiment, unless otherwise specified, "plurality" means two or more.

[0044] When users use electronic devices, they may use them outdoors or under strong light. In this case, the electronic device needs to increase the brightness of the screen to a certain level to ensure that the user can see the screen clearly and provide a good display effect.

[0045] However, the screen brightness level that can meet the needs of outdoor or strong light use is often higher, and to match it, a sufficiently large driving current needs to be provided to drive the screen. Although the screen brightness is improved under high current, it will also cause the temperature of the electronic device to rise rapidly.

[0046] In the current solution, when the screen brightness is kept high, the temperature of the electronic device will reach the temperature protection threshold in a very short time, triggering the high temperature protection mechanism. Once the high temperature protection mechanism is triggered, the screen brightness will be forced to be reduced to a lower level, which is often not enough for outdoor use or under strong light, seriously affecting the user experience.

[0047] In this regard, the present application provides a screen brightness adjustment method, which is applied to an electronic device, including: when the electronic device is in a high-brightness scene, obtaining the device temperature of the electronic device; when the device temperature is greater than or equal to a first temperature threshold, gradually reducing the screen brightness of the electronic device in a linear or nonlinear manner until the device temperature is the same as or close to a second temperature threshold, and the second temperature threshold is greater than the first temperature threshold.

[0048] In the present application, since the screen brightness of the electronic device is adjusted when the electronic device is in a high-brightness scene and reaches the first temperature threshold, the brightness of the electronic device can be gradually reduced until the device temperature is the same as or close to the second temperature threshold. In this process, the screen brightness of the electronic device can always be maintained at a relatively high brightness level without a cliff-like brightness change, giving users a better user experience.

The electronic device 100 detects that the ambient brightness is greater than the first brightness threshold, and determines that the electronic device 100 is in a high-brightness scene. In this case, the electronic device 100 starts to obtain the device temperature. When the device temperature is greater than or equal to the first temperature threshold, the electronic device 100 starts to adjust the screen brightness of the electronic device until the device temperature is the same as or close to the second temperature threshold. During this adjustment process, the screen brightness of the electronic device is gradually reduced, and the screen brightness of the electronic device can always be maintained at a relatively high brightness level, giving the user a better user experience.

The proximity light sensor 180G can also be used in leather case mode and pocket mode to automatically unlock and lock the screen.

[0091] The ambient light sensor 180L is used to sense the ambient light brightness. The electronic device 100 can adaptively adjust the brightness of the display screen 194 according to the perceived ambient light brightness. The ambient light sensor 180L can also be used to automatically adjust the white balance when taking pictures. The ambient light sensor 180L can also cooperate with the proximity light sensor 180G to detect whether the electronic device 100 is in a pocket to prevent accidental touches.

[0092] The fingerprint sensor 180H is used to collect fingerprints. The electronic device 100 can use the collected fingerprint characteristics to implement fingerprint unlocking, access application locks, fingerprint photography, fingerprint call answering, etc.

[0093] The temperature sensor 180J is used to detect temperature. In some embodiments, the electronic device 100 uses the temperature detected by the temperature sensor 180J to execute a temperature processing strategy. For example, when the temperature reported by the temperature sensor 180J exceeds a threshold, the electronic device 100 reduces the performance of a processor located near the temperature sensor 180J to reduce power consumption and implement thermal protection. In other embodiments, when the temperature is lower than another threshold, the electronic device 100 heats the battery 142 to avoid abnormal shutdown of the electronic device 100 due to low temperature. In other embodiments, when the temperature is lower than another threshold, the electronic device 100 performs a boost on the output voltage of the battery 142 to avoid abnormal shutdown caused by low temperature.

[0094] In an embodiment of the present application, the temperature sensor 180J may include multiple ones for detecting the temperatures at different positions of the electronic device 100, such as being set near the processor to obtain the temperature of the processor, being set near the battery to obtain the temperature of the battery, or being set on the inside of the outer casing of the electronic device 100 to obtain the temperature of the outer casing of the electronic device 100.

[0095] The touch sensor 180K is also called a "touch control device". The touch sensor 180K can be set on the display screen 194. The touch sensor 180K and the display screen 194 form a touch screen, also called a "touch control screen". The touch sensor 180K is used to detect touch operations acting on or near it. The touch sensor can pass the detected touch operation to the application processor to determine the type of touch event. Visual output related to the touch operation can be provided through the display screen 194. In other embodiments, the touch sensor 180K can also be set on the surface of the electronic device 100, which is different from the position of the display screen 194.

[0096] The key 190 includes a power key, a volume key, etc. The key 190 may be a mechanical key or a touch key. The electronic device 100 may receive key input and generate key signal input related to user settings and function control of the electronic device 100.

[0097] Motor 191 can generate vibration prompts. Motor 191 can be used for incoming call vibration prompts, and can also be used for touch vibration feedback. For example, touch operations acting on different applications (such as taking pictures, audio playback, etc.) can correspond to different vibration feedback effects. For touch operations acting on different areas of the display screen 194, motor 191 can also correspond to different vibration feedback effects. Different application scenarios (for example: time reminders, receiving messages, alarm clocks, games, etc.) can also correspond to different vibration feedback effects. The touch vibration feedback effect can also support customization.

[0098] The indicator 192 may be an indicator light, which may be used to indicate the charging status, power changes, messages, missed calls, notifications, etc.

[0099] The SIM card interface 195 is used to connect a SIM card. The SIM card can be connected to and separated from the electronic device 100 by inserting it into the SIM card interface 195 or pulling it out from the SIM card interface 195. The electronic device 100 can support 1 or N SIM card interfaces, where N is a positive integer greater than 1. The SIM card interface 195 can support Nano SIM cards, Micro SIM cards, SIM cards, and the like. Multiple cards can be inserted into the same SIM card interface 195 at the same time. The types of the multiple cards can be the same or different. The SIM card interface 195 can also be compatible with different types of SIM cards. The SIM card interface 195 can also be compatible with external memory cards. The electronic device 100 interacts with the network through the SIM card to implement functions such as calls and data communications. In some embodiments, the electronic device 100 uses an eSIM, i.e., an embedded SIM card. The eSIM card can be embedded in the electronic device 100 and cannot be separated from the electronic device 100.

[0100] For the scenario in the above example, the operating system of the electronic device 100 may include but is not limited to Symbian, Android, Windows, MacOS, iOS, Blackberry, HarmonyOS, Linux or Unix operating systems.

[0101] Figure 3 It is a system structure block diagram of the electronic device provided in the embodiment of the present application.

[0102] As an example, when the screen brightness adjustment method provided in the present application is executed on the electronic device 100, the operating system of the electronic device 100 may be Android, and its system structure may refer to Figure 3 .

[0103] Among them, the layered architecture divides the software into several layers, each layer has a clear role and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom, namely, the application layer, the application framework layer, the Android runtime (Android runtime) and the system library, and the kernel layer.

[0104] The application layer can include a series of application packages.

[0105] like Figure 3 As shown, the application package may include camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, short message and other applications.

[0106] The application framework layer provides an application programming interface (API) and a programming framework for the applications in the application layer. The application framework layer includes some predefined functions.

[0107] like Figure 3 As shown, the application framework layer may include a window manager, a content provider, a view system, a phone manager, a resource manager, a notification manager, and the like.

[0108] The window manager is used to manage window programs. The window manager can obtain the display screen size, determine whether there is a status bar, lock the screen, capture the screen, etc.

[0109] Content providers are used to store and retrieve data and make it accessible to applications. The data may include videos, images, audio, calls made and received, browsing history and bookmarks, phone books, etc.

[0110] The view system includes visual controls, such as controls for displaying characters, controls for displaying pictures, etc. 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 message notification icon can include a view for displaying characters and a view for displaying pictures.

[0111] The phone manager is used to provide communication functions for electronic devices, such as the management of call status (including answering, hanging up, etc.).

[0112] The resource manager provides various resources for applications, such as localized strings, icons, images, layout files, video files, and so on.

[0113] The notification manager enables applications to display notification information in the status bar. It can be used to convey notification-type messages and can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify download completion, message reminders, etc. The notification manager can also be a notification that appears in the system top status bar in the form of a chart or scroll bar text, such as notifications of applications running in the background, or a notification that appears on the screen in the form of a dialog window. For example, a text message is displayed in the status bar, a prompt sound is emitted, an electronic device vibrates, an indicator light flashes, etc.

[0114] Android Runtime includes core libraries and virtual machines. Android runtime is responsible for scheduling and management of the Android system.

[0115] The core library consists of two parts: one part is the function that needs to be called by the Java language, and the other part is the Android core library.

[0116] The application layer and the application framework layer run in a virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as object life cycle management, stack management, thread management, security and exception management, and garbage collection.

[0117] The system library may include multiple functional modules, such as surface manager, media library, 3D graphics processing library (such as OpenGL ES), 2D graphics engine (such as SGL), etc.

[0118] The surface manager is used to manage the display subsystem and provide the fusion of 2D and 3D layers for multiple applications.

[0119] The media library supports playback and recording of a variety of commonly used audio and video formats, as well as static image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0120] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, synthesis and layer processing, etc.

[0121] A 2D graphics engine is a drawing engine for 2D drawings.

[0122] The kernel layer is the layer between hardware and software. The kernel layer contains at least display driver, camera driver, audio driver, and sensor driver.

[0123] Figure 4 It is a flowchart of a screen brightness adjustment method provided in an embodiment of the present application.

[0124] refer to Figure 4 , the screen brightness adjustment methods include:

[0125] S401: Detect that the electronic device is in a high-brightness scene. If yes, execute S402; otherwise, continue detecting.

[0126] In some possible implementations, detecting whether the electronic device is in a high-brightness scene may be achieved by detecting the ambient brightness of the electronic device or obtaining the screen brightness of the electronic device.

[0127] As an example, refer to Figure 1 The scenes in Figure 2 In the electronic device structure shown in FIG, when the ambient brightness acquired by the ambient light sensor 180L in the electronic device is greater than or equal to the first brightness threshold, it can be determined whether the electronic device is in a high-brightness scene.

[0128] For example, assuming that the first brightness threshold is 10000 lux (lx) for Figure 1 In the scene, if the ambient light sensor 180L collects an ambient brightness of 12000 lx, it can be determined that the electronic device is in a high-brightness scene.

[0129] In another example, if the ambient brightness is not high (such as only 5000 lx), but the screen brightness is manually set or forced to be increased by some applications. In this case, the brightness of the screen of the electronic device can be obtained, and when the screen brightness is greater than or equal to the second brightness threshold, it can be determined whether the electronic device is in a high-brightness scene.

[0130] For example, assuming that the second brightness threshold is 1000 nits (nit), if the brightness of the screen of the electronic device is obtained to be 1300 nit, it can be determined that the electronic device is in a high-brightness scene.

[0131] S402: Obtain the device temperature of the electronic device.

[0132] For some possible implementations, refer to Figure 2 In the electronic device structure shown in FIG. 1 , the electronic device can obtain the device temperature through the temperature sensor 180J, and the temperature sensor 180J can be set at the inside of the housing of the electronic device, near the processor, or inside the screen. Alternatively, multiple temperature sensors 180J can be set, and the average value of the temperatures collected by the multiple temperature sensors 180J is used as the device temperature.

[0133] S403: Detect that the device temperature is greater than or equal to the first temperature threshold. If yes, execute S404; otherwise, continue detecting.

[0134] In some possible implementations, the first temperature threshold may also become a warning temperature, that is, when the temperature of the electronic device rises to the first temperature threshold, it is necessary to intervene to adjust the screen brightness to ensure that the electronic device does not rapidly increase the device temperature due to the high brightness of the screen and trigger the temperature control protection. As an example, the first temperature threshold may be pre-set, and the first temperature threshold may be less than the temperature at which the temperature control triggers the temperature control protection. For example, the first temperature threshold may be 30°C, 33°C, or 35°C, etc.

[0135] Figure 5 It is a schematic diagram of the change curve of screen brightness, device temperature and time in the screen brightness adjustment method provided in one embodiment of the present application.

[0136] refer to Figure 5, wherein the screen brightness of the electronic device starts to increase at time t1, and it is detected at time t2 that the electronic device is in a high-brightness scene. In this case, S402 and S403 are executed. When it is detected at time t3 that the device temperature is greater than or equal to the first temperature threshold T1, it is determined that intervention is required to adjust the screen brightness.

[0137] S404: Obtain a corresponding brightness adjustment function according to the ambient temperature of the electronic device.

[0138] In some possible implementations, the electronic device has a different temperature environment, and the rate at which the device temperature of the electronic device increases is also different. Therefore, the corresponding brightness adjustment function can be obtained according to the ambient temperature of the electronic device.

[0139] The ambient temperature of the electronic device can be obtained by a temperature sensor disposed on the surface of the electronic device. Alternatively, it can also be obtained through a weather forecast application. Alternatively, it can also be obtained through an intelligent device with a temperature measurement function that is connected to the electronic device for communication. For example, if the environment in which the electronic device is located includes intelligent devices such as an intelligent air conditioner, an intelligent thermometer, and an intelligent air purifier that are connected to the electronic device for communication, the electronic device can request the intelligent device to feedback the ambient temperature to obtain the ambient temperature of the electronic device.

[0140] As an example, for each electronic product, the balanced brightness coefficient of the electronic device under different ambient temperatures can be obtained in advance. The balanced brightness coefficient is the ratio of the balanced screen brightness to the maximum screen brightness. When the screen brightness of the electronic device is maintained at the balanced screen brightness, the device temperature is the same as or close to the second temperature threshold.

[0141] That is, the balanced brightness coefficient K 平 It can be expressed by formula 1:

[0142] K 平 =L 平 / L max (Formula 1)

[0143] Among them, L 平 To balance the screen brightness, L max is the maximum screen brightness.

[0144] Then, a brightness adjustment function of the electronic product under different ambient temperatures is obtained.

[0145] In some possible implementations, the brightness adjustment function may output a brightness adjustment coefficient K, which is related to L max The product of is the target brightness L of the screen.

[0146] As an example, refer to Figure 5, the brightness adjustment coefficient K can be calculated by formula 2 or formula 3:

[0147]

[0148]

[0149] Among them, formula 2 is a linear brightness adjustment function. By adjusting the screen brightness by K in formula 2, linear adjustment of the screen brightness can be achieved. Formula 3 is a nonlinear brightness adjustment function. By adjusting the screen brightness by K in formula 3, nonlinear adjustment of the screen brightness can be achieved.

[0150] Then the target brightness L of the screen can be calculated by formula 4:

[0151] L=K*L max (Formula 4)

[0152] Wherein, T is the device temperature of the electronic device, T2 is the second temperature threshold, that is, the temperature when the screen brightness is maintained at the balanced screen brightness, and T3 is the temperature that triggers the temperature control protection.

[0153] Taking room temperature of 25℃ as an example, T1 can be 35℃, T2 can be 40℃, and T3 can be 42℃.

[0154] As an example, refer to Figure 5 When it is detected at time t3 that the device temperature is greater than or equal to the first temperature threshold T1, the brightness adjustment function of the electronic device (ie, Formula 2 or Formula 3) can be obtained according to the current ambient temperature of the electronic device. Then, S405 is executed according to Formula 2 or Formula 3.

[0155] S405: gradually reduce the screen brightness of the electronic device according to the brightness adjustment function.

[0156] In some possible implementations, referring to the example in S404, when adjusting the screen brightness according to Formula 2 or Formula 3, the threshold of the temperature sensor (sensor) may be set first. For example, the first temperature threshold T1 may be set to 35° C. When the temperature acquired by the temperature sensor is greater than or equal to 35° C., the acquired device temperature T is sent to the display engine.

[0157] The display engine calculates the real-time brightness adjustment coefficient K according to the received temperature T and reference formula 2 or formula 3.

[0158] The display engine may be a software display engine or a hardware display engine. For example, the software display engine may be a display engine service in a framework layer.

[0159] As an example, when the electronic device is a mobile phone, L maxIt can be 1500nit. When the room temperature is 25°C, if the mobile phone load is normal, the screen brightness is 1000nit, which can stabilize the device temperature of the mobile phone at around 40℃ (T2). Then T1 can be set to 35℃. According to the formula in the above example, K can be calculated. 平 When the device temperature is higher than T1, the temperature sensor may report the temperature every 5 seconds, and the device temperature of the electronic device may be the average of the last five temperatures reported by the temperature sensor.

[0160] As an example, the electronic device can also update the brightness adjustment coefficient K every preset temperature. For example, after the device temperature T reaches T1 (35°C), the brightness adjustment coefficient K can be updated every 0.5°C increase. That is, when T rises from 35°C to 35.5°C and above, the brightness adjustment coefficient K can be updated. If it rises from 35°C to 35.4°C, the brightness adjustment coefficient K will not be updated because the temperature rise is less than 0.5°C.

[0161] The above calculation steps can be performed in the display engine service in the Framework. After the brightness coefficient K is calculated, according to K and L max Calculate the target brightness L. Then, send the target brightness to the thread that controls the screen brightness, and combine with the brightness switching module to smoothly switch the screen brightness in a gradual manner.

[0162] For example, the brightness can be sent to the backlight driver (Backlight Driver) of the kernel layer through the brightness control service "lightService", and the brightness can be smoothly adjusted through the Backlight Driver.

[0163] Among them, lightService is a service in the Android system that is used to control the screen brightness. lightService allows the use of functions to set the device's screen brightness. For example, you can adjust the screen brightness by passing a brightness value parameter or using a predefined brightness constant. In this application, the K and L calculated using Formula 2 or Formula 3 are max Multiply them to get the target brightness L, and use the target brightness L as a parameter of the brightness value to adjust the screen brightness.

[0164] The Backlight Driver is used to control the backlight brightness of the screen. The Backlight Driver provides a smooth adjustment function, which can perform smooth brightness transition to avoid obvious changes in brightness adjustment. After receiving the target brightness L, the Backlight Driver performs smooth adjustment based on the difference in backlight brightness between the target brightness L and the current display brightness, and controls the backlight brightness of the screen to display according to the target brightness L.

[0165] S406: Detect that the device temperature is the same as or close to the second temperature threshold. If yes, execute S407; otherwise, continue to execute S405.

[0166] S407. Maintain the screen brightness of the electronic device.

[0167] In some possible implementations, reference is made to Figure 5 When at time t4, it is detected that the device temperature is the same as or close to the second temperature threshold, that is, it is determined that the screen brightness and temperature of the electronic device are balanced, the screen brightness of the electronic device can be maintained. In this case, the device temperature of the electronic device can be maintained at a suitable temperature (T2).

[0168] The device temperature is close to the second temperature threshold, including: the difference between the device temperature and the second temperature threshold is less than or equal to a preset threshold, or the difference between the device temperature and the second temperature threshold is less than or equal to a preset ratio.

[0169] For example, the second temperature threshold is 40°C and the preset threshold is 0.2°C. When the device temperature is 40°C, it is confirmed that the device temperature is the same as the second temperature threshold. When the device temperature is between 39.8°C and 40.2°C, it is confirmed that the device temperature is close to the second temperature threshold.

[0170] For another example, the second temperature threshold is 40°C and the preset ratio is 1%. When the device temperature is 40°C, it is confirmed that the device temperature is the same as the second temperature threshold. When the device temperature is 39.6°C (40°C*99%) to 40.4°C (40°C*101%), it is confirmed that the device temperature is close to the second temperature threshold.

[0171] Figure 6 It is a flow chart of a screen brightness adjustment method provided in another embodiment of the present application.

[0172] refer to Figure 6 , among which S401 to S407 are Figure 4 The process is the same as shown in , and will not be repeated here.

[0173] After S407, the screen brightness adjustment method further includes:

[0174] S408: Detect that the device temperature is greater than or equal to the third temperature threshold. If yes, execute S409; otherwise, continue detecting.

[0175] S409. Gradually reduce the chip performance of electronic devices.

[0176] S410: Detect that the device temperature is the same as or close to the second temperature threshold. If yes, execute S407; otherwise, continue detecting.

[0177] In some possible implementations, when the screen brightness of the electronic device is maintained, the electronic device is operated, resulting in increased power consumption of the electronic device, or a significant change in ambient temperature, both of which may cause the device temperature of the electronic device to rise sharply.

[0178] In this case, if it is detected that the device temperature is greater than or equal to the third temperature threshold (ie, the temperature that triggers temperature control protection), S409 may be executed to reduce device power consumption, thereby reducing the device temperature of the electronic device.

[0179] As an example, the chip performance of the electronic device can be gradually reduced. For example, the screen refresh frequency can be reduced, that is, the GPU rendering frame rate can be reduced, or the chip computing requirements can be reduced, such as reducing the sampling frequency of various sensors on the electronic device, the transmission rate of wireless networks, near-field communications, and Bluetooth, and shutting down the application calculations in the system background. By reducing the chip's computing load and shutting down some of the chip's hardware computing units, the heat generation of the chip and major components can be reduced to prevent the temperature from continuing to rise.

[0180] The method in S410 is the same as that in S406 and will not be described in detail here.

[0181] In this embodiment, when it is detected that the device temperature is greater than or equal to the third temperature threshold, the chip performance of the electronic device is gradually reduced until the device temperature is the same as or close to the second temperature threshold. When the device temperature of the electronic device is too high, the screen brightness can be kept at a high level, and the temperature of the electronic device can be reduced to a reasonable range, thereby providing a better user experience for the user.

[0182] It should be understood that the above examples are intended to help those skilled in the art understand the embodiments of the present application, and are not intended to limit the embodiments of the present application to the specific numerical values ​​or specific scenarios illustrated.

[0183] It is obvious that those skilled in the art can make various equivalent modifications or changes based on the above examples, and such modifications or changes also fall within the scope of the embodiments of the present application.

[0184] Corresponding to the screen brightness adjustment method provided in the above embodiment, Figure 7 This is a structural block diagram of a screen brightness adjustment device provided in an embodiment of the present application. For the sake of convenience of explanation, only the parts related to the embodiment of the present application are shown.
