Title:
DISPLAY DEVICE AND DRIVE METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/053834
Kind Code:
A1
Abstract:
The purpose of the present invention is to minimize the reduction in display quality due to a weak battery in a display device adopting a source shared driving (SSD) scheme. The display device includes a multiplexer that has three switches per one output unit of a source driver so that a data signal can be distributed to three data lines. When a video is displayed, the display device adopts a higher drive frequency than when a still image is displayed and causes the three switches to turn on simultaneously during each horizontal scanning period. When a still image is displayed, the display device adopts a lower drive frequency than when a video is displayed and causes the three switches to turn on sequentially for each prescribed period during each horizontal scanning period.
