[0002] With the rapid development of electronic devices, various mobile devices have become indispensable tools in people's work and life. The refresh rate of the screen of a mobile device has also increased from 60HZ initially to 144HZ now. The screen refresh rate refers to the number of times an image on the screen is repeatedly scanned from top to bottom. The higher the refresh rate, the smoother the displayed image. However, as the screen refresh rate becomes higher and higher, the hardware requirements for the screen also become higher and higher. The light sensor arranged under the screen needs higher sensitivity to quickly adapt to the screen.

[0003] In related technologies, a more sensitive light sensor is usually used to adapt to the screen. However, when the screen changes the screen refresh rate through an internal application, the light sensor cannot obtain the characteristic change of the screen brightness when the screen refresh rate changes, and cannot accurately detect the influence of the external ambient light according to the established prediction method, resulting in unstable and inaccurate screen brightness of the mobile device.

[0035] The example embodiments will be described in detail herein with reference to the attached drawings. The description below refers to the accompanying drawings, which show, by way of example, specific embodiments with which the application can be practiced. The following detailed description is not intended to limit the application. Rather, the following detailed description includes specific details for the purpose of providing a thorough understanding of the inventive concepts. However, it will be apparent to those skilled in the art that the application can be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the application.

[0037] For the purpose of explanation and illustration, specific details of certain embodiments of the application are described below. However, it will be apparent to those skilled in the art that the application can be practiced without these specific details. In some instances, well-known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the application. Figures 1 to 5 A screen brightness adjustment method of a mobile terminal, a mobile terminal, an electronic device, and a storage medium are provided.

[0038] Figure 1 is a flowchart of a screen brightness adjustment method of a mobile terminal in accordance with an example embodiment, comprising the following steps.

[0039] In step S101, a screen brightness target value based on an ambient light value is obtained by a light sensor, wherein the light sensor is arranged on the mobile terminal and communicates with the mobile terminal, the light sensor is used to detect ambient light and obtain screen leakage, and the ambient light value is obtained based on the ambient light and the screen leakage.

[0040] Specifically, before adjusting the screen brightness of the mobile terminal, the target value of the screen brightness needs to be obtained first to determine whether the target value of the current screen brightness is consistent with the current screen brightness of the mobile terminal. When they are consistent, the screen brightness of the mobile terminal does not need to be adjusted. When they are not consistent, the screen brightness of the mobile terminal is adjusted according to the target value of the screen brightness until the screen brightness of the mobile terminal is consistent with the target value of the screen brightness. The light sensor is arranged below the screen of the mobile terminal. The ambient light can be detected by the light sensor arranged below the screen. There is a certain screen leakage when the screen refresh rate changes. The screen leakage of the mobile terminal will affect the ambient light value. Therefore, the ambient light detected by the light sensor and the leakage caused by the screen leakage of the mobile terminal are obtained. The ambient light value is calculated. The light sensor transmits the calculated ambient light value to the mobile terminal through communication for the later brightness control process.

[0041] Further, the screen brightness target value obtained based on the ambient light value through the light sensor comprises:

[0042] The ambient light value is obtained from the light sensor;

[0043] The screen brightness target value is calculated based on the ambient light value.

[0044] Specifically, the ambient light and the light leakage generated by the screen of the mobile terminal are detected and obtained through the light sensor, and the difference between the two can reduce the influence of the light leakage of the screen of the mobile terminal on the detection of the ambient light by the light sensor, so as to obtain the ambient light value. The screen brightness target value corresponding to the ambient light value is obtained by calculating the obtained ambient light value.

[0045] Further, the screen brightness target value obtained based on the ambient light value through the light sensor comprises:

[0046] The screen brightness target value is directly obtained from the light sensor, wherein the screen brightness target value is obtained by the light sensor based on the ambient light value.

[0047] Specifically, the light sensor is internally integrated with a micro control unit (MCU) or a digital signal processor (DSP) or other computing modules. Through the MCU or DSP or other hardware computing modules, the screen brightness target value can be calculated and obtained based on the ambient light detected by the light sensor and the screen light leakage obtained. The screen brightness target value can be directly obtained by the mobile terminal through wireless communication.

[0048] Further, it further comprises:

[0049] The plurality of screen refresh rate samples and the corresponding screen light leakage are obtained.

[0050] The plurality of screen refresh rate samples and the corresponding screen light leakage are trained to obtain the light leakage influence model.

[0051] Specifically, since the influence of the same value of screen light leakage on screens with different refresh rates is different, the plurality of screen refresh rate samples and the corresponding screen light leakage values are used as corresponding training parameters through a neural network model, and the corresponding light leakage influence model is obtained after training.

[0052] Further, the screen light leakage is input into the light leakage influence model to obtain the screen light leakage, wherein the light leakage influence model is obtained by pre-training according to a plurality of screen refresh rate samples and corresponding screen light leakage as labels.

[0053] Specifically, by inputting the values of different screen refresh rates into the light leakage influence model, the corresponding light leakage values of the screen can be directly obtained, and then the corresponding ambient light values can be calculated.

[0054] Further, the light sensor is provided with a cache unit to cache the ambient light values.

[0055] Specifically, by setting a cache unit in the light sensor, the ambient light values calculated by the screen at the current refresh rate are stored in the cache unit.

[0056] Further, the ambient light values obtained by the light sensor include:

[0057] The ambient light values are obtained from the cache unit of the light sensor.

[0058] Specifically, when the mobile terminal needs to adjust the screen brightness of the mobile terminal, the ambient light values are directly obtained from the cache unit, the screen brightness target value is calculated based on the ambient light values, and the screen brightness of the mobile terminal is changed based on the screen brightness target value. By setting the cache unit, the multiple steps of frequently obtaining the ambient light detected by the light sensor and calculating the screen light leakage are avoided, and when the same conditions are detected, the existing ambient light values in the cache unit can be directly obtained, thereby reducing the power consumption of the system.

[0059] In step S102, the screen brightness of the mobile terminal is adjusted based on the screen brightness target value.

[0060] Specifically, when the screen brightness target value is determined, the screen brightness of the mobile terminal is directly adjusted by the upper application layer of the mobile terminal.

[0061] In order to further illustrate the technical idea of the present application, now combined with specific application scenarios, such as Figure 4 The screen brightness target value specific application scenario block diagram shown in FIG. 1 is used to illustrate the technical solution of the present application.

[0062] Step 1: Obtain the ambient light detected by the light sensor and the screen light leakage obtained by the light leakage influence model inside the light sensor. Alternatively, as shown in the multi-channel photodiode spectral array diagram of Figure 7 The screen of the mobile terminal is composed of multiple light emitting diodes of different colors, and different colors of light emitting diodes have different light leakage effects on the same brightness, such as Figure 6The spectrum envelope area represents the light leakage value of different color light, and the light leakage values of multiple channels of light emitting diodes are calculated by a hardware calculation module such as MCU or DSP in the light sensor, and then are added to obtain the screen light leakage.

[0063] In the second step, the MCU or DSP calculates and obtains the ambient light value after reducing the influence of screen light leakage based on the data of ambient light and screen light leakage detected by the light sensor.

[0064] In the third step, the calculated ambient light value is stored in the cache unit of the light sensor.

[0065] In the fourth step, the MCU or DSP in the light sensor obtains the ambient light value from the cache unit and obtains the screen brightness target value by calculation.

[0066] In order to further illustrate the technical idea of the present application, the specific application scenarios are combined as follows: Figure 5 The screen brightness target value reporting and brightness display adjustment block diagram of the light sensor is shown, and the technical scheme of the present application is described.

[0067] In the first step, the screen brightness target value calculated by the light sensor is obtained.

[0068] In the second step, the screen brightness target value is uploaded to the driver program in the kernel space through the driver program in the sensor concentrator.

[0069] In the third step, the screen brightness target value is transmitted to the hardware abstraction layer in the user space through the driver program in the kernel space.

[0070] In the fourth step, the hardware abstraction layer transmits data to the operating system, and the operating system transmits data to the application layer.

[0071] In the fifth step, after receiving the data, the application layer sends an instruction to the operating system, and sends an instruction to the display driver through the display management system, so that the screen brightness of the current mobile terminal is the screen brightness target value.
