Abstract

The invention relates to a method for adjusting backlight brightness of a terminal screen. The method comprises: obtaining a current value of a brightness slider; according to mapping relations of a preset value of the brightness slider and brightness adjusting values, and the current value of the brightness slider, generating a current brightness adjusting value, wherein the mapping relations ofthe preset value of the brightness slider and brightness adjusting values are quadratic function relations; and according to the current brightness adjusting value, adjusting backlight brightness of aterminal screen. The method for adjusting backlight brightness of a terminal screen improves backlight brightness adjusting effect, and improves user experience. The invention also provides a systemfor adjusting backlight brightness of a terminal screen.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and system for adjusting the brightness of a backlight of a terminal screen. Background technique [0002] When adjusting the backlight of the terminal screen, there are often problems that the backlight brightness cannot be finely adjusted in the weak backlight range, and the brightness adjustment is slow when adjusted in the strong backlight range. The existing backlight adjustment scheme adopts segmented adjustment, which divides the brightness of the backlight into multiple levels, divides the value of the brightness slider used to adjust the brightness of the backlight into multiple numerical intervals, and adjusts the different numerical intervals of the brightness slider. Map to different backlight brightness levels according to different linear relationships. When the brightness slider slides to a certain value range, the backlight brightness of the terminal ...
