Problems solved by technology
This will cause the brightness of the screen to be too dim, and the content of the screen cannot be clearly displayed.
Furthermore, when the occluder is removed, the screen brightness adjustment method in the prior art will brighten the screen brightness again, resulting in multiple adjustments of the screen brightness and reducing the life of the screen
[0004] To sum up, the problem existing in the screen brightness adjustment method in the prior art is that the adjustment is performed solely based on the light intensity sensed by the ambient light detection sensor, and there is a phenomenon of misadjustment.

The invention discloses a screen luminance adjustment method and an electronic device based on an ambient light detecting sensor. The method comprises a first step of obtaining distance information of a shielding object and the ambient light detecting sensor if the shielding object is detected to be close to the ambient light detecting sensor of the electronic device, a second step of judging whether the distance information is larger than a presetting threshold value or not to obtain a judgment result, a third step of adjusting the luminance of a display unit according to ambient light luminance information detected by the ambient light detecting sensor if the judgment result shows that the distance information is larger than the preset threshold value, and a fourth step of keeping the present luminance of the display unit unchangeable if the judgment result shows that the distance information is less than or equal to the preset threshold value. By means of the method and the electronic device, the screen luminance can be adjusted by combining of the distance between the shielding object and the ambient light detecting sensor, the phenomenon of mistakenly adjusting is avoided, service life of a screen is prolonged, and user experience is improved.
Description
technical field [0001] The invention relates to the field of sensor control, in particular to a screen brightness adjustment method and electronic equipment based on an ambient light detection sensor. Background technique [0002] Current electronic devices, especially various portable terminals, usually have a screen brightness automatic adjustment function. The function of automatically adjusting the screen brightness mainly refers to automatically adjusting the brightness of the screen according to the intensity of ambient light around the screen of the electronic device. Specifically, when the light intensity of the ambient light is relatively high, the brightness of the screen of the electronic device is correspondingly increased; when the light intensity of the ambient light is low, the brightness of the screen of the electronic device is correspondingly reduced. In this way, the purpose of saving power and improving user experience can be achieved. [0003] However,...
