This embodiment will be described from the perspective of a device for adjusting screen brightness. Specifically, the device may be integrated in an electronic device, and the electronic device may be an electronic device including an ambient light sensor (such as a smart phone, a tablet computer).

Referring first to FIG. 1 , FIG. 1 is a schematic plan view of a display screen provided by an embodiment of the present invention. The display screen 21 includes a display area 215 and a non-display area 216 . Wherein, the display area 215 performs the display function of the display screen 21 for displaying information. The non-display area 216 does not display information. The display screen 21 may include a plurality of non-display areas 216 spaced apart from each other. For example, non-display areas 216 are respectively provided on the top and bottom of the display screen 21 . The non-display area 216 can be used to set functional components such as a camera, a receiver, and a fingerprint module.

Wherein, the ambient light sensor 213 is disposed in the display area 215 of the screen 21 , for example, the ambient light sensor is disposed at the upper left corner of the display area 215 as shown in FIG. 1 .

In some embodiments, the display screen 21 may be a liquid crystal display (Liquid Crystal Display, LCD) or an organic light-emitting diode display (Organic Light-Emitting Diode, OLED) or other type of display. When the display screen 21 is a liquid crystal display screen, the display layer may include a backlight plate, a lower polarizer, an array substrate, a liquid crystal layer, a color filter substrate, and an upper polarizer that are stacked in sequence.

Fig. 2 is a schematic flow chart of a method for adjusting screen brightness provided by an embodiment of the present application. The method is applied to an electronic device, and the electronic device includes an ambient light sensor arranged in a display area of the screen. The above-mentioned ambient light detection includes the following steps:

Step S101, acquiring a first light intensity value currently detected by an ambient light sensor.

Considering that the adjustment of the screen brightness needs to be carried out when the screen is turned on, and there is no need to adjust the screen brightness when the screen is turned off. Therefore, in an embodiment, before obtaining the first light intensity value currently detected by the ambient light sensor, it may also be determined whether the electronic device is in a bright screen state, and if so, obtain the first light intensity value currently detected by the ambient light sensor . Specifically, the screen is in the bright screen state as the trigger condition. When monitoring the process of the system application program, it is judged whether the screen of the electronic device is in the bright screen state. When it is monitored that the capacitive touch screen is lit, it means the screen is in In the bright screen state, the first light intensity value currently detected by the ambient light sensor is acquired.

In an embodiment, before acquiring the first light intensity value currently detected by the ambient light sensor, it may be determined whether the current screen backlight of the electronic device is in an automatic adjustment mode. Specifically, in the framework layer of Android design, the power management module (PowerManager) sets a listener for the database used by the setting module, and monitors the item of automatic backlight in the database. When the item of automatic backlight changes, it monitors The device will monitor it, and then update the local record, so the backlight adjustment mode set by the user can be detected at any time, and can be read directly when needed. Among them, when the automatic backlight mode change in the database is monitored, the following code will be called to perform a state synchronization. In this implementation, if the electronic device is not currently in the automatic backlight adjustment mode, that is, in the manual backlight adjustment mode, there is no need to obtain the first light intensity value currently detected by the ambient light sensor. If the electronic device is currently in the automatic backlight adjustment mode , then perform acquiring the first light intensity value currently detected by the ambient light sensor.

Among them, the ambient light sensor is mainly composed of photosensitive elements. At present, photosensitive elements are developing rapidly, with various varieties and wide applications. There are photoresistors, photodiodes, phototransistors, and silicon photocells on the market. The ambient light sensor can sense the surrounding light conditions and inform the processing chip to automatically adjust the brightness of the display backlight to reduce the power consumption of the product. For example, in the application of handheld devices such as mobile phones, notebooks, GPS, etc., the display consumes up to 30% of the total battery power, and the use of ambient light sensors can maximize the working time of the battery. On the other hand, the ambient light sensor helps the display provide a soft picture. When the ambient brightness is high, the LCD display using the ambient light sensor will automatically adjust to high brightness. When the outside environment is dark, the display will be adjusted to low brightness.

In an embodiment, the light intensity values detected by the ambient light sensor may be obtained for a predetermined number of times, and then the average value of the multiple light intensity values is calculated to be the first light intensity value. Among them, the preset number of times above can be set according to the actual situation, such as 10 times, and data is collected every 1 second to obtain 10 consecutive sampling data of the ambient light sensor in the electronic device within 10 seconds. In a stable (such as indoor environment), the data jump is very small, basically in single digits, such as 501nits, 505nits, 503nits and other readings. After obtaining the above-mentioned multiple light intensity values, all the above-mentioned values can be added together, and then divided by the number to obtain the average light intensity value of the multiple light intensity values. For example, within a preset period of time, the light intensity value of the ambient light sensor is sampled n times to obtain n light intensity values such as Q1, Q2, Q3...Qn, etc., and Q1+Q2+Q3+...+Qn is calculated and The average light intensity value can be obtained by dividing the result by n, which is the first light intensity value.

Step S102, acquiring a second light intensity value of the ambient light sensor, where the second light intensity value is the light intensity value detected by the ambient light sensor after the screen of the electronic device is turned on in a dark environment.

In the embodiment of the present invention, the above-mentioned second light intensity value may be the current light intensity value measured by the ambient light sensor when only the screen of the electronic device is turned on when there is no ambient light in the laboratory environment. In some embodiments, it is also possible to obtain the light intensity values detected by the ambient light sensor for preset times, and then calculate the average value of multiple light intensity values, which is the second light intensity value. This step is the same as in the above step S101, I won't repeat them here.

Step S103, calculating a target light intensity value according to the first light intensity value and the second light intensity value.

In the embodiment of the present invention, since the ambient light is set under the display area of the screen, the brightness of the screen will interfere with the measurement of the ambient light sensor. The first light intensity value includes the light generated by the ambient light screen, so the first light The intensity value will be higher than the second light intensity value. Specifically, the difference between the first light intensity value and the second light intensity value can be calculated, the difference is the target light intensity value after eliminating screen interference, and the target light intensity value is closer to the light intensity of the current ambient light value.

Step S104, adjusting the screen brightness of the electronic device according to the target light intensity value.

Among them, in actual use, different ambient light intensity values correspond to different screen brightnesses. The larger the ambient light intensity value, the greater the corresponding screen brightness, that is, the brighter the display screen; correspondingly, the smaller the ambient light intensity value , the corresponding screen brightness is smaller, that is, the display screen is darker. There are many methods for adjusting the screen brightness of the electronic device according to the target light intensity value. In one embodiment, the corresponding relationship between the light intensity value and the screen brightness can be preset. After the target light intensity value is obtained, the above corresponding Find the target screen brightness corresponding to the target light intensity value in the relationship, and then control the brightness of the screen to adjust to the target screen brightness.

In other embodiments, the corresponding relationship between a plurality of light intensity value ranges and screen brightness can also be preset, and after obtaining the target light intensity value, it is judged that the target light intensity value falls into the light intensity value range, and then the corresponding light intensity value of the range is determined. The screen brightness is the target screen brightness, and the brightness of the control screen is adjusted to the target screen brightness.

It can be known from the above that the screen brightness adjustment method provided by the embodiment of the present application can obtain the first light intensity value currently detected by the ambient light sensor, and then obtain the second light intensity value of the ambient light sensor, and the second light intensity value is After the screen is turned on in a dark environment, the ambient light sensor detects the light intensity value, calculates the target light intensity value according to the first light intensity value and the second light intensity value, and adjusts the screen brightness of the electronic device according to the target light intensity value. This application pre-detects the interference value of the brightness of the display screen on the ambient light sensor in a dark environment, so the ambient light sensor can be calibrated according to the interference value during use, so that the measurement data is more accurate, and the accuracy of screen brightness adjustment can be improved.

According to the description of the previous embodiment, the screen brightness adjustment method of the present application will be further described below.

Please refer to FIG. 3. FIG. 3 is a schematic flowchart of another method for adjusting screen brightness provided by the embodiment of the present application, including the following steps:

Step S201, acquiring a first light intensity value currently detected by an ambient light sensor.

In actual use, the adjustment of the screen brightness needs to be carried out when the screen is turned on, and there is no need to adjust the screen brightness when the screen is turned off. Therefore, in an embodiment, before obtaining the first light intensity value currently detected by the ambient light sensor, it may also be determined whether the electronic device is in a bright screen state, and if so, obtain the first light intensity value currently detected by the ambient light sensor . Specifically, the screen is in the bright screen state as the trigger condition. When monitoring the process of the system application program, it is judged whether the screen of the electronic device is in the bright screen state. When it is monitored that the capacitive touch screen is lit, it means the screen is in In the bright screen state, the first light intensity value currently detected by the ambient light sensor is obtained.

Step S202, acquiring a second set of light intensity values of the ambient light sensor, the set including a plurality of second light intensity values detected by the ambient light sensor at different brightnesses of the screen of the electronic device in a dark environment.

Considering that the light intensity values measured by the ambient light sensor may be different under different brightness of the screen, in order to further improve the accuracy, in an embodiment, the second set of light intensity values of the ambient light sensor may be obtained, set includes a plurality of second light intensity values detected by the ambient light sensor at different brightness levels of the screen of the electronic device in a dark environment. Wherein, the above-mentioned second light intensity value may be the current light intensity value measured by the ambient light sensor when only the screen of the electronic device is turned on when there is no ambient light in the laboratory environment.

Step S203, acquiring the current brightness of the screen of the electronic device.

Considering that under the same screen brightness, the light intensity generated by the screen when displaying different images may also be different, so the brightness of the display area corresponding to the ambient light sensor can be further acquired. In an embodiment, the luminance values of all pixels in the display area corresponding to the ambient light sensor may be acquired, and then the average luminance value thereof is calculated and determined as the current luminance of the screen of the electronic device. That is, the step of obtaining the current brightness of the screen of the electronic device may include:

Obtain the brightness value of each pixel in the screen area corresponding to the ambient light sensor;

An average brightness value is calculated according to the brightness value of each pixel, and the average brightness value is determined to be the current brightness of the screen of the electronic device.

In one embodiment, the size of the screen area corresponding to the ambient light sensor can be 1cm×1cm, that is, 1cm ² . In other embodiments, the area of the screen area corresponding to the ambient light sensor can also be measured by pixel For example, in a display screen with a resolution of 1920×1080, it means that the number of pixels in the image is 2073600, and the screen area corresponding to the ambient light sensor can be 100×50 or 5000 area of pixels. The present invention makes no further limitation on this.

In one embodiment, the brightness value of each pixel in the screen area corresponding to the ambient light sensor can be obtained, specifically, the brightness value of each pixel can be extracted, recorded and stored in the form of a matrix, so that the brightness value can be directly called later , and then calculate the average brightness value of the area, for example, add the obtained brightness values of each pixel and divide by the number of pixels to generate the current brightness value of the screen area corresponding to the ambient light sensor. Among them, the red component, green component and blue component (red, green, blue, RGB) of each pixel can be converted into hue, saturation and brightness value (Hue, saturation, , value, HSV), to obtain the brightness value of each pixel.

Step S204, searching for a corresponding second light intensity value in the second light intensity value set according to the current brightness, and determining it as the target second light intensity value.

Step S205, calculating the difference between the first light intensity value and the second light intensity value, and determining the difference as a target light intensity value.

In the embodiment of the present invention, since the ambient light is set under the display area of the screen, the brightness of the screen will interfere with the measurement of the ambient light sensor. The first light intensity value includes the light generated by the ambient light screen, so the first light The intensity value will be higher than the second light intensity value. Specifically, the difference between the first light intensity value and the second light intensity value can be calculated, the difference is the target light intensity value after eliminating screen interference, and the target light intensity value is closer to the light intensity of the current ambient light value.

In step S206, it is judged whether the screen area corresponding to the ambient light sensor receives a touch operation, if not, execute step S207, and if yes, end the current process.

In actual use, since the above-mentioned ambient light sensors are all set in the display area of the screen, and the display area is also the touch area of the electronic device, when the user performs a touch operation on the electronic device, there may be user fingers or stylus Blocking above the ambient light sensor will result in inaccurate measured light intensity values, so it can be judged whether the ambient light sensor is blocked, and if not, proceed to the next step.

Wherein, the above-mentioned determination of whether the ambient light sensor is blocked can be performed by judging whether the screen area corresponding to the ambient light sensor receives a touch operation. If blocked, go to step S207.

Step S207, adjusting the screen brightness of the electronic device according to the target light intensity value.

Among them, different ambient light intensity values correspond to different screen brightnesses. The larger the ambient light intensity value, the greater the corresponding screen brightness, that is, the brighter the display screen; correspondingly, the smaller the ambient light intensity value, the corresponding screen The smaller the brightness, the darker the display screen. There are many methods for adjusting the screen brightness of the electronic device according to the target light intensity value. In one embodiment, the corresponding relationship between the light intensity value and the screen brightness can be preset. After the target light intensity value is obtained, the above corresponding Find the target screen brightness corresponding to the target light intensity value in the relationship, and then control the brightness of the screen to adjust to the target screen brightness.

It can be seen from the above that the embodiment of the present application can obtain the first light intensity value currently detected by the ambient light sensor, and obtain the second light intensity value set of the ambient light sensor, which includes the screen of the electronic device in a dark environment under different brightness environments. A plurality of second light intensity values detected by the light sensor, obtaining the current brightness of the screen of the electronic device, searching the corresponding second light intensity value in the second light intensity value set according to the current brightness, and determining it as the target second light intensity value , calculate the difference between the first light intensity value and the second light intensity value, and determine that the difference is the target light intensity value, judge whether the screen area corresponding to the ambient light sensor receives a touch operation, if not, then according to the target light intensity The value adjusts the screen brightness of the electronic device. This application can pre-detect the interference value of the brightness of the display screen on the ambient light sensor in a dark environment, so the ambient light sensor can be calibrated according to the interference value during use, so that the measurement data is more accurate, and the accuracy of screen brightness adjustment can be improved. .
