Title:
DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/151227
Kind Code:
A1
Abstract:
A display device comprising a compensation drive circuit and m-1 compensation lines connected to the compensation drive circuit, wherein the compensation drive circuit generates m-1 compensation signals and respectively inputs same to the m-1 compensation lines; and the m-1 compensation lines and m-1 second data lines in each second data line group other than the last second data line respectively form a compensation capacitor at an overlapping position. By means of adding m-1 compensation lines, the effect of making the feed-through voltage received by each column of pixels of a display panel uniform can be achieved. The problem of poor display caused by the closing of a gating switch can be solved, thereby saving on circuit space and reducing additional power consumption caused by compensation.
