Document Type and Number:
WIPO Patent Application WO/2022/077718
Kind Code:
A1
Abstract:
A display panel and a display device. The display panel comprises a source driver chip (SD); the source driver chip (SD) comprises a charging compensation module (100); and the charging compensation module (100) comprises a plurality of cascaded shift registers (SR) used for time-divisionally outputting a plurality of pulse signals (Sout), and a plurality of level shift circuits (LS) used for turning on time-divisionally in response to the plurality of pulse signals (Sout), so as to prevent the problem of electromagnetic interference due to superposition of current peaks caused by the plurality of level shift circuits (LS) outputting a plurality of currents at the same time.
