Abstract: The present disclosure relates to a method and device for controlling brightness of a touch screen of an electronic device. The method includes determining an object is operating on the touch screen; selecting a number N of sampling light sensors which are not blocked by an object from ambient light among the light sensors distributed on the touch screen, and controlling brightness of the touch screen based on the number N of sampling light sensors.

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.
