PRESET REVERSE DRIVE METHOD APPLIED IN VIDEO DISPLAYING PROCESS

Document Type and Number:

WIPO Patent Application WO/2018/214667

Kind Code:

A1

Abstract:

Disclosed in the present invention is a preset reverse drive method applied in a video displaying process. The method comprises the steps of: pre-obtaining display content of several frames behind lit pixels in a video by means of content loading; and adding a reverse drive signal before each forward drive signal used for driving the display content of the several frames, to suppress electric charge concentration on pixels in a video display panel in advance. The reverse drive signal changes the potential barrier of the defect potential well, removes electric charges confined and concentrated in the potential well, and reduces the density of confined electric charges. Thus, the video display brightness is improved, and the service life of the video display panel is prolonged.
