[0043] The technical solution in this application will be described below with reference to the accompanying drawings.

[0044] In the description of the embodiments of this application, unless otherwise specified, " / " represents or. For example, A / B can represent A or B. "And / or" in this article is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of this application, "plurality" means two or more than two.

[0045] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, 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.

[0046] When using electronic devices outdoors or under strong sunlight, users may need to increase the screen brightness to a certain level to ensure that users can see the screen clearly and provide good display effects.

[0047] However, screen brightness levels that meet the requirements for outdoor use or under strong sunlight are often higher, and to match this, a sufficiently large drive current is required to drive the screen. Although high current improves screen brightness, it also causes the entire electronic device to heat up rapidly.

[0048] With the current solution, when the screen brightness remains high, the entire electronic device's temperature quickly reaches the temperature protection threshold, triggering the overheat protection mechanism. Once triggered, the overheat protection mechanism forcibly reduces the screen brightness to a lower level, which is often insufficient for outdoor use or in strong sunlight, severely impacting the user experience.

[0049] 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.

[0050] In this 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. During this process, the screen brightness of the electronic device can always be maintained at a relatively high brightness level without cliff-like brightness changes, providing users with a better user experience.

[0051] FIG1 is a schematic diagram of an application scenario of a screen brightness adjustment method provided in an embodiment of the present application.

[0052] With reference to FIG1 , the application scenario of the embodiment of the present application is first briefly described.

[0053] FIG1 shows an electronic device 100. When a user uses the electronic device 100 outdoors under sunlight, the sunlight intensity is relatively high. 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.

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.

The gyroscope sensor 180B can be used for anti-shake shooting. For example, when the shutter is pressed, the gyroscope sensor 180B detects the angle of the electronic device 100 shaking, calculates the distance that the lens module needs to compensate based on the angle, and allows the lens to offset the shaking of the electronic device 100 through reverse movement to achieve anti-shake. The gyroscope sensor 180B can also be used for navigation and somatosensory game scenes.

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 the 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 prevent the electronic device 100 from shutting down abnormally due to low temperature. In other embodiments, when the temperature is lower than another threshold, the electronic device 100 boosts the output voltage of the battery 142 to prevent abnormal shutdown due to low temperature.

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, at a location different from that of the display screen 194.

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.

[0100] The indicator 192 may be an indicator light, which may be used to indicate the charging status, power level changes, messages, missed calls, notifications, etc.

[0101] The SIM card interface 195 is used to connect a SIM card. The SIM card can be connected to or disconnected from the electronic device 100 by inserting it into or removing it 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.

[0102] 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.

[0103] FIG3 is a system structure block diagram of an electronic device provided in an embodiment of the present application.

[0104] As an example, when the screen brightness adjustment method provided in the present application is run on the electronic device 100, the operating system of the electronic device 100 may be Android, and its system structure may refer to FIG3 .

[0105] The layered architecture divides software into several layers, each with distinct roles and responsibilities. Layers communicate with each other via software interfaces. In some embodiments, the Android system is divided into four layers: the application layer, the application framework layer, the Android runtime and system libraries, and the kernel layer.

[0106] The application layer can include a series of application packages.

[0107] As shown in FIG3 , the application package may include applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video, and short message.

[0113] The phone manager is used to provide communication functions for electronic devices, such as call status management (including answering, hanging up, etc.).

[0114] The resource manager provides various resources for applications, such as localized strings, icons, images, layout files, video files, and so on.

[0115] 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.

[0116] Android Runtime includes core libraries and a virtual machine. Android runtime is responsible for scheduling and management of the Android system.

[0117] 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.

[0118] 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.

[0119] The system library can 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.

[0120] The surface manager is used to manage the display subsystem and provide fusion of 2D and 3D layers for multiple applications.

[0121] 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.

[0122] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing and layer processing.

[0123] A 2D graphics engine is a drawing engine for 2D drawings.

[0124] 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.

[0125] FIG4 is a flow chart of a method for adjusting screen brightness according to an embodiment of the present application.

[0126] Referring to FIG4 , the screen brightness adjustment method includes:

[0127] S401: Detect that the electronic device is in a highlight scene. If yes, execute S402; otherwise, continue detecting.

[0128] In some possible implementations, detecting whether the electronic device is in a high-brightness scene can be achieved by detecting the ambient brightness of the electronic device or obtaining the screen brightness of the electronic device.

[0129] As an example, referring to the scene in Figure 1 and the electronic device structure shown in Figure 2, 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.

[0130] For example, assuming that the first brightness threshold is 10,000 lux (lx), for the scene in FIG1 , if the ambient brightness illuminance collected by the ambient light sensor 180L is 12,000 lx, it can be determined that the electronic device is in a high-brightness scene.

[0131] In another example, if the ambient brightness is not high (e.g., 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 electronic device's screen 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.

[0132] 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.

[0133] S402: Acquire the device temperature of the electronic device.

[0134] In some possible implementations, referring to the electronic device structure shown in FIG2 , the electronic device can obtain the device temperature via a temperature sensor 180J. The temperature sensor 180J can be located inside the housing of the electronic device, near the processor, or inside the screen. Alternatively, multiple temperature sensors 180J can be provided, and the average of the temperatures collected by the multiple temperature sensors 180J can be used as the device temperature.

[0135] S403: Detect that the device temperature is greater than or equal to the first temperature threshold. If so, execute S404; otherwise, continue detecting.

[0136] In some possible implementations, the first temperature threshold can also serve as a warning temperature. That is, when the temperature of the electronic device rises to the first temperature threshold, it is necessary to intervene and adjust the screen brightness to ensure that the electronic device does not rapidly increase the device temperature due to high screen brightness and trigger thermal control protection. As an example, the first temperature threshold can be pre-set and can be lower than the temperature at which thermal control triggers thermal control protection. For example, the first temperature threshold can be 30°C, 33°C, or 35°C.

[0137] FIG5 is a schematic diagram of a curve showing changes in screen brightness, device temperature, and time in a screen brightness adjustment method provided in an embodiment of the present application.

[0138] Referring to Figure 5 , at time t1, the screen brightness of the electronic device begins to increase, and at time t2, the electronic device is detected to be in a high-brightness scene. In this case, S402 and S403 are executed. When, at time t3, it is detected 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.

[0139] S404: Obtain a corresponding brightness adjustment function according to the ambient temperature of the electronic device.

[0140] In some possible implementations, the electronic device's temperature rise rate may be different due to different ambient temperatures. Therefore, a corresponding brightness adjustment function may be obtained based on the ambient temperature of the electronic device.

[0141] The ambient temperature of the electronic device can be obtained by a temperature sensor provided on the surface of the electronic device. Alternatively, it can be obtained through a weather forecast application. Alternatively, it can be obtained through a smart device with a temperature measurement function that is communicatively connected to the electronic device. For example, if the environment in which the electronic device is located includes smart devices such as a smart air conditioner, a smart thermometer, or a smart air purifier that are communicatively connected to the electronic device, the electronic device can request the smart device to feedback the ambient temperature to obtain the ambient temperature of the electronic device.

[0142] As an example, for each electronic product, a balanced brightness coefficient of the electronic device under different ambient temperatures can be pre-acquired. 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 remains at the balanced screen brightness, the device temperature is the same as or close to the second temperature threshold.

[0143] That is, the balanced brightness coefficient K 平 It can be expressed by formula 1: K 平 =L 平 / L max (Formula 1)

[0144] Among them, L 平 To balance the screen brightness, L max is the maximum screen brightness.

[0145] Then, a brightness adjustment function of the electronic product under different ambient temperatures is obtained.

[0146] 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.

[0147] As an example, referring to FIG5 , the brightness adjustment coefficient K can be calculated by Formula 2 or Formula 3:

[0148] 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.

[0149] The target brightness L of the screen can be calculated by formula 4: L = K * L max (Formula 4)

[0150] Where T is the device temperature of the electronic device, T2 is the second temperature threshold, that is, the temperature at which the screen brightness is maintained at the balanced screen brightness, and T3 is the temperature at which the temperature control protection is triggered.

[0151] Taking the room temperature of 25℃ as an example, T1 can be 35℃, T2 can be 40℃, and T3 can be 42℃.

[0152] As an example, referring 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 (i.e., 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.

[0153] S405: gradually reduce the screen brightness of the electronic device according to the brightness adjustment function.

[0154] In some possible implementations, referring to the example in S404, when adjusting screen brightness according to Formula 2 or Formula 3, a temperature sensor threshold may be set first. For example, the first temperature threshold T1 may be set to 35°C. When the temperature obtained by the temperature sensor is greater than or equal to 35°C, the obtained device temperature T is sent to the display engine.

[0155] The display engine calculates the real-time brightness adjustment coefficient K according to the received temperature T and reference formula 2 or formula 3.

[0156] 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.

[0157] For example, when the electronic device is a mobile phone, L max It can be 1500nit. When the room temperature is 25°C, if the mobile phone load is normal, the screen brightness is 1000nit, which can make the device temperature of the mobile phone stable 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 can report the temperature every 5 seconds, and the device temperature of the electronic device can be the average of the last 5 temperatures reported by the temperature sensor.

[0158] As an example, the electronic device can also update the brightness adjustment coefficient K at preset temperature intervals. 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 or above, the brightness adjustment coefficient K can be updated. If it rises from 35°C to 35.4°C, the brightness adjustment coefficient K is not updated because the temperature increase is less than 0.5°C.

[0159] The above calculation steps can be performed in the display engine service of 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 it with the brightness switching module to smoothly switch the screen brightness in a gradual manner.

[0160] 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 by the Backlight Driver.

[0161] 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 screen brightness of the device. 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.

[0162] The Backlight Driver controls the screen's backlight brightness. It provides smooth adjustment, enabling smooth brightness transitions to avoid noticeable brightness changes. Upon receiving the target brightness L, the Backlight Driver smoothly adjusts the backlight brightness based on the difference between the target brightness L and the current display brightness, controlling the screen's backlight brightness to match the target brightness L.

[0163] S406: Detect that the device temperature is the same as or close to the second temperature threshold. If so, execute S407; otherwise, continue to execute S405.

[0164] S407. Maintain the screen brightness of the electronic device.

[0165] In some possible implementations, referring to FIG5 , 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 of the electronic device is balanced with the temperature, 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).

[0166] The device temperature being close to the second temperature threshold includes: the difference between the device temperature and the second temperature threshold being less than or equal to a preset threshold, or the difference between the device temperature and the second temperature threshold being less than or equal to a preset ratio.

[0167] 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.

[0168] For another example, the second temperature threshold is 40°C and the preset ratio is 1%. When the device temperature is 40°C, the device temperature is confirmed to be the same as the second temperature threshold. When the device temperature is between 39.6°C (40°C * 99%) and 40.4°C (40°C * 101%), the device temperature is confirmed to be close to the second temperature threshold.

[0169] FIG6 is a flow chart of a method for adjusting screen brightness according to another embodiment of the present application.

[0170] Referring to FIG. 6 , steps S401 to S407 are the same as those in FIG. 4 , and are not described in detail herein.

[0171] After S407, the screen brightness adjustment method further includes:

[0172] S408: Detect that the device temperature is greater than or equal to a third temperature threshold. If so, execute S409; otherwise, continue detecting.

[0173] S409. Gradually reduce the chip performance of the electronic device.

[0174] S410: Detect that the device temperature is the same as or close to the second temperature threshold. If so, execute S407; otherwise, continue detecting.

[0175] In some possible implementations, when the screen brightness of the electronic device is maintained, operating the electronic device causes the power consumption of the electronic device to increase, or the ambient temperature changes significantly, both of which may cause the device temperature of the electronic device to rise sharply.

[0176] 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.

[0177] For example, gradually reducing the chip performance of an electronic device can involve lowering the screen refresh rate, that is, reducing the GPU rendering frame rate. Alternatively, the chip's computing requirements can be reduced, such as by lowering the sampling frequency of various sensors on the electronic device, the transmission rate of wireless networks, near-field communications, and Bluetooth, and disabling background computing applications. By reducing the chip's computing load and disabling some of the chip's hardware computing units, the heat generated by the chip and its key components can be reduced, preventing continued temperature increases.

[0178] The method in S410 is the same as that in S406 and will not be described in detail here.

[0179] In this embodiment, when the device temperature is detected to be greater than or equal to the third temperature threshold, the chip performance of the electronic device is gradually reduced until the device temperature is equal to or close to the second temperature threshold. This ensures that the screen brightness remains at a high level while also reducing the temperature of the electronic device to a reasonable range when the device temperature is too high, providing a better user experience.

[0180] 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.
