Title:
GOA CIRCUIT AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2021/184544
Kind Code:
A1
Abstract:
A GOA circuit (611) and a display panel (600). The GOA circuit (611) comprises multi-stage cascaded GOA units, each GOA unit comprising: a pull-up control module (301), a pull-up module (302), a download module (303), a pull-down maintenance module (304), a pull-down module (305), and a bootstrap capacitor (Cb). The pull-up module (302) of the GOA circuit (611) is configured as two thin film transistors (T21 and T21'), which respectively input different oscillation signals (LC1 and LC2), have independent output ports (A1 and A2), and can alternately operate so as to reduce the stress time of a single thin film transistor (T21 or T21'), reducing a threshold voltage offset and prolonging the service life of a device.
