Document Type and Number:
WIPO Patent Application WO/2019/007098
Kind Code:
A1
Abstract:
The present disclosure relates to a driving device and a driving method of a display panel and a display device. The driving device comprises: a driving unit configured to output a driving signal for driving a subpixel; and a compensation unit connected to the driving unit and fanout lines of a fanout region and configured to compensate, according to a reference impedance and the driving signal, impedance of the fanout lines, the fanout region comprising a plurality of fanout lines, and the reference impedance being the maximum impedance of the impedance of the fanout lines or impedance greater than the maximum impedance. The present disclosure can minimize the influence of impedance differences between fanout lines on a driving signal output to a pixel, so as to improve image display quality.
