Abstract

The invention discloses a display screen automatic discharge method, a display screen and a mobile terminal. The display screen automatic discharge method includes the steps that a display screen sleep instruction is sent to a display screen; the display screen is controlled to display an all white image or all black image; the display screen is controlled to release charge in the display screen; the display screen is controlled to get into a sleep mode. By means of the method, the purpose of automatic discharge of the display screen can be achieved, and the problem of a splash screen is solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display screen automatic discharge method, a display screen and a mobile terminal. Background technique [0002] In modern life, after the mobile phone lights up the screen and runs for a period of time, use the power button to turn off the screen, and then turn it on again, there will be a flickering screen problem (in the interface of making a call, use the light sensor to turn off the screen, and then turn on the screen will also have a flickering screen problem) . This is because after the screen goes to sleep, the internal charge is not released and remains in the display screen. The unreleased charge drives the liquid crystal with DC. After a long time, the two poles of the liquid crystal accumulate charge, resulting in a DC residue. When the screen is turned on again, The normal AC driving voltage plus the accumulated DC residual electric field makes the ...
