Abstract

This application provides a method for adjusting display screen brightness, an electronic device, and a storage medium. The method includes: setting display screen brightness in response to an automatic brightness setting instruction; adjusting the display screen brightness in response to a brightness setting instruction generated by manually adjusting brightness by a user; determining, when a display screen is on again after the display screen is off, whether a mechanism of clearing the display screen brightness manually adjusted is triggered; if the mechanism of clearing the display screen brightness manually adjusted is triggered, setting the display screen brightness again in response to the automatic brightness setting instruction; determining, in response to an operation of manually adjusting the display screen brightness again, whether the operation of manually adjusting the display screen brightness again is the same as a previous operation of manually adjusting the display screen brightness.

First claim

What is claimed is:

1. A method for adjusting display screen brightness, comprising:
setting display screen brightness in response to an automatic brightness setting instruction;
adjusting the display screen brightness in response to a brightness setting instruction generated by manually adjusting brightness;
determining, when a display screen is on again after the display screen is off, whether a mechanism of clearing the display screen brightness manually adjusted is triggered;
based on the mechanism of clearing the display screen brightness manually adjusted being triggered, setting the display screen brightness again in response to the automatic brightness setting instruction;
determining, in response to an operation of manually adjusting the display screen brightness again, whether the operation of manually adjusting the display screen brightness again is the same as a previous operation of manually adjusting the display screen brightness; and
based on the operation of manually adjusting the display screen brightness again being the same as the previous operation of manually adjusting the display screen brightness, adjusting, in response to a brightness setting instruction generated by manually adjusting the display screen brightness again, the display screen brightness set again;
wherein the determining, in response to the operation instruction of manually adjusting the display screen brightness again, whether the operation of manually adjusting the display screen brightness again is the same as the previous operation of manually adjusting the display screen brightness comprises:
when the display screen detects an operation of manually adjusting a brightness bar again, determining whether the operation of manually adjusting the brightness bar again is the same as a previous operation of manually adjusting the brightness bar;
based on determining that the operation of manually adjusting the brightness bar again is the same as the previous operation of manually adjusting the brightness bar, determining that the operation of manually adjusting the display screen brightness again is the same as the previous operation of manually adjusting the display screen brightness; and
based on determining that the operation of manually adjusting the brightness bar again is different from the previous operation of manually adjusting the brightness bar, determining that the operation of manually adjusting the display screen brightness again is different from the previous operation of manually adjusting the display screen brightness.

2. The method for adjusting display screen brightness according to claim 1 , wherein the setting display screen brightness in response to the automatic brightness setting instruction comprises:
determining whether a use scenario of an electronic device is a preset first use scenario or a preset second use scenario;
based on determining that the use scenario of the electronic device is the preset first use scenario, determining a brightness value in a first brightness range as the display screen brightness;
based on determining that the use scenario of the electronic device is the preset second use scenario, determining a brightness value in a second brightness range as the display screen brightness;
mapping the determined display screen brightness in the first brightness range or the second brightness range to display screen brightness in a third brightness range; and
driving the display screen to perform display based on the display screen brightness in the third brightness range.

3. The method for adjusting display screen brightness according to claim 2 ,
wherein the preset first use scenario comprises: the electronic device runs a video application, the electronic device runs two-dimensional code software, or the electronic device is in a front-facing camera fill-in light state; and
wherein the preset second use scenario comprises: the electronic device is in a thermal limit state, the electronic device is in a front-facing camera brightness limit state, the electronic device is in a low power mode, the electronic device is in a face unlock state, or the electronic device is in a scene recognition state.

4. The method for adjusting display screen brightness according to claim 2 , wherein the setting display screen brightness in response to the automatic brightness setting instruction comprises:
sensing, when the display screen is on, ambient light brightness of an environment of the electronic device by using an ambient light sensor;
determining, in response to an automatic brightness setting instruction generated based on the ambient light brightness, a preset ambient light brightness interval within which the ambient light brightness falls;
determining, based on a correspondence between the brightness value in the second brightness range and the preset ambient light brightness interval, display screen brightness corresponding to the preset ambient light brightness interval within which the ambient light brightness falls;
mapping the display screen brightness in the second brightness range to the display screen brightness in the third brightness range; and
driving the display screen to perform display based on the display screen brightness in the third brightness range.

5. The method for adjusting display screen brightness according to claim 4 , wherein the sensing, when the display screen is on, the ambient light brightness of the environment of the electronic device by using the ambient light sensor comprises:
based on the display screen being switched from a screen-off state to a screen-on state, generating a trigger instruction to trigger the ambient light sensor to sense ambient light, converting a sensed optical signal into an electrical signal, converting the electrical signal into brightness information, and generating the automatic brightness setting instruction based on the brightness information.

6. The method for adjusting display screen brightness according to claim 4 , wherein the sensing, when the display screen is on, the ambient light brightness of the environment of the electronic device by using the ambient light sensor comprises:
based on the display screen being in a screen-on state, sensing, by the ambient light sensor, ambient light at a preset sampling rate, converting a sensed optical signal into an electrical signal, converting the electrical signal into brightness information, and generating the automatic brightness setting instruction based on the brightness information when the brightness information changes and lasts for a preset time.

7. The method for adjusting display screen brightness according to claim 4 , wherein a mapping relationship among brightness values in the first brightness range, the second brightness range, and the third brightness range comprises: a brightness value in the first brightness range corresponds to a brightness value in the second brightness range or a sub-brightness range of the second brightness range, the sub-brightness range of the second brightness range corresponds to a sub-brightness range of the third brightness range, and a brightness value in the second brightness range corresponds to a brightness value in the third brightness range or a sub-brightness range of the third brightness range.

8. The method for adjusting display screen brightness according to claim 4 , wherein the first brightness range is from 0 to 1, the second brightness range is from 0 to 255, and the third brightness range is from 0 to 10000.

9. The method for adjusting display screen brightness according to claim 4 , wherein the driving the display screen to perform the display based on the display screen brightness in the third brightness range comprises:
