Abstract

Disclosed is a screen brightness adjustment method. The method includes that: a current battery power value and a current screen brightness value of a terminal are acquired; a target screen brightness range suitable for the acquired current battery power value is selected by taking the current screen brightness value as a baseline; a screen brightness value corresponding to the current battery power value is selected according to power consumption values corresponding to all selected brightness values in the target screen brightness range; and display is performed according to the selected screen brightness value. The disclosure also discloses a screen brightness adjustment apparatus.

Description

technical field [0001] The invention relates to the technical field of LCD display in terminal systems, in particular to a method and device for adjusting screen brightness. Background technique [0002] With the continuous development and progress of science and technology, terminal functions are becoming more and more complex, such as camera function, handwriting function, music playback function, video phone function, terminal TV function, etc. Terminals have also developed from ordinary terminals to smart terminals. However, as the functions of the terminal become more and more complex, the power consumption increases, and the standby time of the terminal becomes an obstacle to the rapid development of the terminal. [0003] As terminal functions become more and more complex and powerful, there are more and more terminals with large screens. However, the larger the screen of the terminal, the greater the power consumption. Generally, the screen of the terminal uses an ...
