Abstract
The present disclosure provides a display panel and a display device. The display panel includes source driver chips. The source driver chips include charging compensation modules, and each of the charging compensation modules includes: a plurality of shift registers cascadely connected and configured to time-divisionally output a plurality of pulse signals, and a plurality of level shift circuits time-divisionally conducted in response to the plurality of the pulse signals to prevent the plurality of the level shift circuits in the source driver chips from outputting and generating a plurality electron currents at a same time, which would result in a superposition of current peaks and cause electromagnetic interference problems.
Claims19
A display panel, wherein the display panel comprises source driver chips, the source driver chips comprise charging compensation modules, and each of the charging compensation modules comprises:
