Abstract: Methods and an apparatus for setting brightness of a display screen of an electronic device based on ambient light brightness. The method includes acquiring by a light sensor on the electronic device a measured brightness of ambient light having an actual ambient brightness at where the electronic device is located; detecting whether the light sensor faces away from a light source in the environment; when it is detected that the light sensor does not face away from the light source, determining a reference backlight brightness level according to a backlight brightness level-setting function comprising a correspondence between actual ambient brightness levels and backlight brightness levels, by using the measured brightness as actual ambient brightness; and setting an actual backlight brightness of the backlighted display screen to the reference backlight brightness level; and when it is detected that the light sensor faces away from the light source, setting the actual backlight brightness of the backlighted display screen at a level different from the reference backlight brightness level.

Abstract: A display method, device and a computer-readable medium are provided. The method includes: detecting whether there is any change in a displayed content for the display; in response to detecting that the displayed content for the display does not change, controlling the display to alternately update display data corresponding to a first portion and a second portion of display units in each row when the display unit comprises m rows of pixels; and in response to detecting that the displayed content for the display does not change, controlling the display to alternately update display data corresponding to a third portion and a fourth portion of display units in each column when the display unit comprises n columns of pixels. Herein m and n are positive integers. Thus, screen flicker caused by reduction of refresh frequency of a display while the display content does not change can be avoided.
