[0047] The embodiments of the present application provide a method, device, electronic device and storage medium for adjusting the screen backlight brightness, which are used to readjust the screen backlight brightness by dynamically adjusting the minimum backlight level and / or the maximum backlight level, so as to reduce the discomfort caused by the different light sensitivities of different users. Different users can find the minimum backlight level and / or the maximum backlight level that suits them.

[0048] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All embodiments in the present invention should fall within the scope of protection of the present invention.

[0049] The following is a brief description of some professional terms involved in this application:

[0050] Backlight: Backlight is a measure of the brightness of the screen display.

[0051] LUX: Lux, the ambient light value, is used to measure the luminous flux received by a light sensor. Lux, legally symbolized as lx, is the unit of luminance. When a uniformly illuminated object receives 1 lumen per square meter, its illuminance is 1 lux.

[0052] nit: A unit used to measure the brightness of a screen. Nit is a unit of brightness, with 1 nit = 1 cd / m². Brightness refers to the physical quantity that measures the intensity of light emitted (or reflected) by the surface of a light source (or reflector). When the human eye observes a light source from one direction, the ratio of the light intensity in that direction to the area of ​​the light source "seen" by the eye is defined as the unit brightness of that light source, or the luminous intensity per unit projected area. The unit of brightness is candela per square meter (cd / m²). Brightness is the human perception of light intensity. Brightness refers to the degree of brightness of an object, defined as the luminous intensity per unit area, and is measured in nits, with 1 nit = 1 candela per square meter. Lumen (LM) is the unit of luminous flux.

[0053] HBM: High Brightness Model, high brightness mode, the screen brightness is higher than the maximum backlight level.

[0054] With the widespread use of mobile phones and other electronic devices, screen background brightness has attracted increasing attention, even becoming a standard for measuring the quality of mobile phones. Different mobile phones and screens have different backlight display ranges. For example, some screens support 2047 backlight levels, while others support 4095 backlight levels, and some even support 10,000-level dimming technology. The higher the backlight level, the higher the screen background brightness. Conversely, the lower the backlight level, the lower the screen background brightness. Screen background brightness, also known as backlight, is also called backlight.

[0055] In the embodiment of the present application, the electronic device may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or a wireless terminal device in a smart home, etc.

[0056] As an example and not a limitation, in the embodiments of the present application, the electronic device may also be a wearable device. Wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0057] like Figure 1 FIG. 1 is a schematic diagram of an embodiment of a method for adjusting screen backlight brightness according to an embodiment of the present application, which may include:

[0058] 101. In response to a user adjusting operation on a minimum backlight level control bar, obtain a current minimum backlight level; and / or, in response to a user adjusting operation on a maximum backlight level control bar, obtain a current maximum backlight level.

[0059] Optionally, the responding to the user's adjustment operation on the minimum backlight level control bar to obtain the current minimum backlight level; and / or responding to the user's adjustment operation on the maximum backlight level control bar to obtain the current maximum backlight level may include: responding to the user's adjustment operation on the minimum backlight level control bar to obtain the current minimum backlight level; and / or responding to the user's adjustment operation on the maximum backlight level control bar to obtain the current maximum backlight level.

[0060] It is understandable that the response to the user's adjustment operation on the lowest backlight level control bar may be a sliding adjustment operation; and / or the response to the user's sliding adjustment operation on the highest backlight level control bar may be a sliding adjustment operation.

[0061] Optionally, before step 101 , the method may further include: setting the minimum backlight level control bar and the maximum backlight level control progress bar.

[0062] It is understandable that based on the problem of fixed minimum and maximum brightness proposed in the prior art, this application provides a solution that can be dynamically adjusted by the user from the electronic device side. A minimum backlight level control progress bar and a maximum backlight level control progress bar are designed. Figure 2 As shown in FIG, a schematic diagram of the minimum backlight level control progress bar and the maximum backlight level control progress bar in the embodiment of the present application. Figure 3 The figure shows a schematic diagram of a user adjusting the minimum backlight level control progress bar in an embodiment of the present application.

[0063] 102. Adjust the screen backlight brightness according to the current minimum backlight level and / or the current maximum backlight level.

[0064] Optionally, adjusting the screen backlight brightness according to the current minimum backlight level and / or the current maximum backlight level may include:

[0065] According to the current minimum backlight level, the default minimum backlight level and the default minimum screen backlight brightness, the current minimum screen backlight brightness is obtained; and / or, according to the current maximum backlight level, the default maximum backlight level and the default maximum screen backlight brightness, the current maximum screen backlight brightness is obtained; according to the current minimum backlight level and the current minimum screen backlight brightness, and / or, the current maximum backlight level and the current maximum screen backlight brightness, the configuration curve is adjusted; according to the adjusted configuration curve, the screen backlight brightness is adjusted.

[0066] Optionally, obtaining the current minimum screen backlight brightness according to the current minimum backlight level, the default minimum backlight level, and the default minimum screen backlight brightness may include:

[0067] According to the first formula, the current minimum screen backlight brightness is obtained;

[0068] The first formula is: ;

[0069] in, is the default minimum backlight level, is the default minimum screen backlight brightness, is the current minimum backlight level, is the current minimum screen backlight brightness;

[0070] Obtaining the current maximum screen backlight brightness according to the current maximum backlight level, the default maximum backlight level, and the default maximum screen backlight brightness may include:

[0071] According to the second formula, the current maximum screen backlight brightness is obtained;

[0072] The second formula is: ;

[0073] in, is the default maximum backlight level, is the default maximum screen backlight brightness, is the current maximum backlight level, is the current maximum screen backlight brightness.

[0074] Optionally, the screen backlight brightness corresponding to the current minimum backlight level is less than or greater than the screen backlight brightness corresponding to the default minimum backlight level; and the screen backlight brightness corresponding to the current maximum backlight level is less than or greater than the screen backlight brightness corresponding to the default maximum backlight level. That is, it can be understood that the current minimum backlight level adjusted by the user is different from the default minimum backlight level, and the current maximum backlight level adjusted by the user is different from the default maximum backlight level.

[0075] Optionally, the adjustable range of the minimum backlight level corresponding to the minimum backlight level control bar is [first minimum backlight level, second minimum backlight level], the screen backlight brightness corresponding to the first minimum backlight level is lower than the screen backlight brightness corresponding to the default minimum backlight level, and the screen backlight brightness corresponding to the second minimum backlight level is higher than the screen backlight brightness corresponding to the default minimum backlight level;

[0076] The adjustable range of the maximum backlight level corresponding to the maximum backlight level control bar is [first maximum backlight level, second maximum backlight level]. The screen backlight brightness corresponding to the first maximum backlight level is less than the screen backlight brightness corresponding to the default maximum backlight level, and the screen backlight brightness corresponding to the second maximum backlight level is greater than the screen backlight brightness corresponding to the default maximum backlight level.

[0077] For example, regarding the setting of the minimum backlight level control bar, in the prior art, the minimum backlight level is generally set to around 8, corresponding to a minimum screen backlight brightness of around 10 nits. 8 can be considered the default minimum backlight level, but in reality, the minimum screen brightness level can be as low as 0. For some users, the default minimum backlight level of 8, corresponding to a screen brightness of 10 nits, is already dim enough. Therefore, the minimum backlight level can be set higher, so that, for example, the adjustable range of the minimum backlight level can be set to [0, 16]. The minimum backlight level options can be {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16}; or {0, 2, 4, 6, 8, 10, 12, 14, 16}; or {0, 4, 8, 12, 16}, etc., without specific limitation.

[0078] However, it should be noted that if the minimum backlight level is set to 0, it will be completely black and completely invisible. Therefore, in this application, it is not recommended to set the minimum backlight level to 0. For example, the adjustable range of the minimum backlight level can be set to [1, 15]. Then, the options for the minimum backlight level can be {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}; or {1, 3, 5, 7, 9, 11, 13, 15}, or {1, 5, 9, 13}, etc., without specific limitation; for example, the adjustable range of the minimum backlight level can also be set to [2, 14]. Then, the options for the minimum backlight level can be {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14}, or {2, 4, 6, 8, 10, 12, 14}; or {4, 8, 12}, etc., without specific limitation.

[0079] For example, regarding the setting of the maximum backlight level control bar, the maximum screen backlight brightness varies depending on the screen type and hardware support. The current default maximum backlight level is based on the 2047 standard, which corresponds to a maximum screen backlight brightness of 460 (nit). The maximum backlight value level range varies a bit. For example, the maximum backlight level (maxBrightness) can be adjusted in the range of [1747, 2347]. It can be adjusted in 100 units as a gradient. Like the minimum backlight brightness, it can have three steps on each side. Then, the maximum backlight level options can be {1747, 1847, 1947, 2047, 2147, 2247, 2347}; it can also be adjusted in 50 units as a gradient. Then, the maximum backlight level options can be {1747, 1797, 1847, 1897, 1947, 1997, 2047, 2097, 2147, 2197, 2247, 2297, 2347}; it can also be adjusted in other units as a gradient, and there is no specific limitation.

[0080] Optionally, the default minimum backlight level is an intermediate level between the first minimum backlight level and the second minimum backlight level; and the default maximum backlight level is an intermediate level between the first maximum backlight level and the second maximum backlight level.

[0081] It is understandable that the default minimum backlight level and the default maximum backlight level are the default minimum backlight level and the default maximum backlight level in the prior art, because in the prior art, the default minimum backlight level is the lowest backlight level, which cannot be lowered, and the default maximum backlight level is the highest backlight level, which cannot be higher. In the implementation of the present application, the default minimum backlight level is the middle level between the first minimum backlight level and the second minimum backlight level, that is, the center level. For users, the selection level of the highest minimum backlight level and the selection level of the lowest backlight level are the same, which fully and fairly considers the needs of users. Then, for some users, in some scenarios, they feel that the screen backlight brightness corresponding to the default minimum backlight level is too high, and they can lower it further. For some users, in some scenarios, they feel that the screen backlight brightness corresponding to the default minimum backlight brightness level is too low, and they can higher it. The default maximum backlight level is the middle level between the first maximum backlight level and the second highest backlight level, that is, the center level. For users, the selection level of the highest backlight level is the same as the selection level of the highest backlight level, which fully and fairly considers the needs of users. For some users, in some scenes, they feel that the screen backlight brightness corresponding to the default maximum backlight level is too high, and they can lower it further. For some users, in some scenes, they feel that the screen backlight brightness corresponding to the default maximum backlight brightness level is too low, and they can increase it further.

[0082] For example, assuming the default minimum backlight level is 8, the minimum backlight level control bar corresponds to an adjustable range of {2, 4, 6, 8, 10, 12, 14}, with 8 being the middle level of the adjustable range. Assuming the default maximum backlight level is 2047, the maximum backlight level control bar corresponds to an adjustable range of {1747, 1847, 1947, 2047, 2147, 2247, 2347}, with 2047 being the middle level of the adjustable range.

[0083] Optionally, there is at least one minimum backlight level between the first minimum backlight level and the default minimum backlight level, and there is at least one minimum backlight level between the default minimum backlight level and the second minimum backlight level;

[0084] There is at least one maximum backlight level between the first maximum backlight level and the default maximum backlight level, and there is at least one maximum backlight level between the default maximum backlight level and the second maximum backlight level.

[0085] For example, assuming that the adjustable range of the minimum backlight level [first minimum backlight level, second minimum backlight level] is [1, 15], 8 is the default minimum backlight level, and the options for the minimum backlight level are {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}, then there are 6 minimum backlight levels between the first minimum backlight level and the default minimum backlight level, and there are 6 minimum backlight levels between the default minimum backlight level and the second minimum backlight level. assuming that the adjustable range of the minimum backlight level [first minimum backlight level, second minimum backlight level] is set to [2, 14], 8 is the default minimum backlight level, and the options for the minimum backlight level are {2, 4, 6, 8, 10, 12, 14}, then there are 2 minimum backlight levels between the first minimum backlight level and the default minimum backlight level, and there are 2 minimum backlight levels between the default minimum backlight level and the second minimum backlight level.

[0086] Assuming that the adjustable range of the maximum backlight level [first maximum backlight level, second maximum backlight level] is [1747, 2347], the default maximum backlight level is 2047, and the maximum backlight level choices are {1747, 1847, 1947, 2047, 2147, 2247, 2347}, then there are 2 maximum backlight levels between the first maximum backlight level and the default maximum backlight level, and there are 2 maximum backlight levels between the default maximum backlight level and the second maximum backlight level.

[0087] It is understandable that the present application can set up two additional progress bars in the electronic device, namely: a minimum backlight level control progress bar and a maximum backlight level control progress bar. Then, the current minimum backlight level and / or the current maximum backlight level that the user adjusts for the minimum backlight level control progress bar and / or the maximum backlight level control progress bar are obtained; the electronic device adjusts the screen backlight brightness according to the current minimum backlight level and / or the current maximum backlight level. The minimum backlight level control progress bar can also be called the minimum backlight level brightness control progress bar, and the maximum backlight level control progress bar can also be called the maximum backlight level brightness control progress bar. The screen backlight brightness can also be called the screen display brightness.

[0088] It is understood that this application adjusts the screen brightness in the following manner, as shown below:

[0089] (1) Adjust the screen backlight brightness by adjusting the minimum backlight level control bar and / or the maximum backlight level control bar.

[0090] When the user slides the minimum backlight level control bar and / or the maximum backlight level control bar, the electronic device responds to the user's sliding operation, obtains the current minimum backlight level, and / or, obtains the current maximum backlight level, thereby adjusting the minimum screen backlight brightness and / or the maximum screen backlight brightness of the electronic device.

[0091] (2) Adjust the screen backlight brightness by adjusting the configuration curve

[0092] You can adjust the value storage database and monitor it through the manual backlight level control bar to get the current minimum backlight level (minBrightness) and / or the current maximum backlight level (maxBrightness); then calculate the current minimum screen backlight brightness ( ), and / or, the current maximum screen backlight brightness ( ); Use the automatic backlight algorithm to interpolate values ​​(minBrightness, )(maxBrightness, ) Readjust the configuration curve to adjust the screen backlight brightness.

[0093] For example, if the minimum backlight level adjustable range is set to [2, 14], three gradients can be set to 2 on the left of the default value of 8, and 3 gradients can be designed to 14 on the right. That is, the current minimum backlight level (minBrightness) adjustable range is [2, 14], and the minimum screen backlight brightness (nit) changes linearly. , we get 8 / 10 = minBrightness / , is the current minimum screen backlight brightness, find .

[0094] For example, if the maximum backlight level adjustable range is set to [1747, 2347], that is, the current maximum backlight level (maxBrightness) adjustable range is [1747, 2347]. ; get 2047 / 450 = maxBrightness / , is the current maximum screen backlight brightness, find .

[0095] It should be noted that, no matter which method is used, the maximum backlight level and / or the minimum backlight level corresponding to the backlight level control bar can be adjusted, thereby achieving the purpose of changing the screen display brightness.

[0096] The technical solution of this application readjusts the adjustable range of the screen backlight brightness by dynamically adjusting the minimum backlight level and / or the maximum backlight level; or, regenerates the configuration curve to reduce the discomfort caused by different users' different light sensitivities. In this way, users can find the minimum or maximum screen backlight brightness that suits them; and the maximum value can also be integrated into the configuration curve (HBM) and adjusted through the backlight level control bar.

[0097] In an embodiment of the present application, in response to a user's adjustment operation on the minimum backlight level control bar, the current minimum backlight level is obtained; and / or, in response to a user's adjustment operation on the maximum backlight level control bar, the current maximum backlight level is obtained; and the screen backlight brightness is adjusted based on the current minimum backlight level and / or the current maximum backlight level. By dynamically adjusting the minimum backlight level and / or the maximum backlight level, the screen backlight brightness is readjusted to reduce discomfort caused by different light sensitivities among different users, allowing different users to find the minimum backlight level and / or the maximum backlight level that suits them.

[0111] There is at least one maximum backlight level between the first maximum backlight level and the default maximum backlight level, and there is at least one maximum backlight level between the default maximum backlight level and the second maximum backlight level.

[0112] like Figure 5 As shown, it is a schematic diagram of an embodiment of an electronic device in the embodiment of the present application, which may include Figure 4 The device shown is used to adjust the brightness of the screen backlight.

[0113] like Figure 6 FIG. 1 is a schematic diagram of another embodiment of the electronic device in the embodiment of the present application. The electronic device may include:

[0114] Figure 6 The block diagram shows a partial structure of a mobile phone related to the electronic device provided in the embodiment of the present application. Figure 6 The mobile phone includes components such as a radio frequency (RF) circuit 610, a memory 620, an input unit 630, a display unit 640, a sensor 650, an audio circuit 660, a wireless fidelity (Wi-Fi) module 670, a processor 680, and a power supply 690. It will be understood by those skilled in the art that Figure 6 The mobile phone structure shown in the figure does not constitute a limitation to the mobile phone, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0115] The following combination Figure 6 A detailed introduction to the various components of a mobile phone:

[0116] The RF circuit 610 can be used to receive and transmit signals during information transmission or calls. Specifically, it receives downlink information from the base station and transmits it to the processor 680 for processing. Furthermore, it transmits uplink data to the base station. Typically, the RF circuit 610 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier (LNA), a duplexer, and the like. Furthermore, the RF circuit 610 can communicate with the network and other devices via wireless communications. Such wireless communications can utilize any communication standard or protocol, including but not limited to Global System of Mobile Communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, and Short Messaging Service (SMS).

[0117] Memory 620 can be used to store software programs and modules. Processor 680 executes the software programs and modules stored in memory 620 to execute various functional applications and data processing of the mobile phone. Memory 620 may primarily include a program storage area and a data storage area. The program storage area may store an operating system and at least one application required for a function (such as sound playback or image playback). The data storage area may store data generated based on the use of the mobile phone (such as audio data and a phone book). Memory 620 may also include high-speed random access memory and non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state memory device.

[0118] The input unit 630 is used to receive input digital or character information and generate key signal input related to user settings and function control of the mobile phone. Specifically, the input unit 630 may include a touch panel 631 and other input devices 632. The touch panel 631, also known as a touch screen, can detect user touch operations on or near it (for example, operations performed on or near the touch panel 631 using a finger, stylus, or any other suitable object or accessory) and drive corresponding connected devices according to a pre-set program. Optionally, the touch panel 631 may include a touch detection device and a touch controller. The touch detection device detects the user's touch position and detects signals generated by the touch operation, transmitting the signals to the touch controller. The touch controller receives the touch information from the touch detection device, converts it into touch point coordinates, and then sends it to the processor 680. The touch controller can also receive and execute commands from the processor 680. Furthermore, the touch panel 631 can be implemented using various types of sensors, including resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 631, the input unit 630 may further include other input devices 632. Specifically, the other input devices 632 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, power keys, etc.), a trackball, a mouse, and a joystick.

[0119] The display unit 640 can be used to display information input by the user or information provided to the user and various menus of the mobile phone. The display unit 640 may include a display panel 641. Optionally, the display panel 641 may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc. Further, the touch panel 631 may cover the display panel 641. When the touch panel 631 detects a touch operation on or near it, it is transmitted to the processor 680 to determine the type of touch event. Subsequently, the processor 680 provides corresponding visual output on the display panel 641 according to the type of touch event. Although in Figure 6 In the embodiment, the touch panel 631 and the display panel 641 are used as two independent components to realize the input and output functions of the mobile phone, but in some embodiments, the touch panel 631 and the display panel 641 can be integrated to realize the input and output functions of the mobile phone.

[0120] The mobile phone may also include at least one sensor 650, such as a light sensor, a motion sensor, or other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor. The ambient light sensor can adjust the brightness of the display panel 641 based on the brightness of the ambient light, and the proximity sensor can turn off the display panel 641 and / or the backlight when the phone is brought to the ear. An accelerometer, a type of motion sensor, can detect acceleration in all directions (generally three axes) and, when stationary, can detect the magnitude and direction of gravity. This can be used for applications that recognize the phone's posture (such as switching between landscape and portrait modes, related games, and magnetometer posture calibration), vibration recognition-related functions (such as pedometers and tapping), and other functions. Other sensors that may be configured in the mobile phone, such as a gyroscope, barometer, hygrometer, thermometer, and infrared sensor, are not described here.

[0121] Audio circuit 660, speaker 661, and microphone 662 provide an audio interface between the user and the phone. Audio circuit 660 converts received audio data into electrical signals and transmits them to speaker 661, which then converts them into sound signals for output. Microphone 662, on the other hand, converts collected sound signals into electrical signals, which are then received by audio circuit 660 and converted into audio data. The audio data is then processed by processor 680 and then transmitted to, for example, another phone via RF circuit 610. Alternatively, the audio data can be output to memory 620 for further processing.

[0122] Wi-Fi is a short-range wireless transmission technology. The mobile phone can help users send and receive emails, browse the web and access streaming media through the Wi-Fi module 670. It provides users with wireless broadband Internet access. Figure 6 A Wi-Fi module 670 is shown, but it is understandable that it is not an essential component of the mobile phone and can be omitted as needed without changing the essence of the application.

[0123] Processor 680 is the control center of the mobile phone, connecting all parts of the phone using various interfaces and circuits. By running or executing software programs and / or modules stored in memory 620 and accessing data stored in memory 620, it performs various functions of the mobile phone and processes data, thereby providing overall monitoring of the mobile phone. Optionally, processor 680 may include one or more processing units; preferably, processor 680 may integrate an application processor and a modem processor, wherein the application processor primarily handles the operating system, user interface, and application programs, while the modem processor primarily handles wireless communications. It is understood that the modem processor may not be integrated into processor 680.

[0124] The mobile phone also includes a power supply 690 (such as a battery) for supplying power to various components. Preferably, the power supply can be logically connected to the processor 680 through a power management system, so that the power management system can manage charging, discharging, and power consumption.

[0125] Although not shown, the mobile phone may also include a camera, a Bluetooth module, etc., which will not be described in detail here.
