Title:
GOA CIRCUIT AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2021/248614
Kind Code:
A1
Abstract:
A GOA circuit and a display panel. In terms of a circuit structure, the number of thin film transistors required for an inverter is reduced, and the reduction of the number of transistors can effectively reduce the area occupied by a GOA region, thereby facilitating reducing the frame size of a panel; gates of thin film transistors in the GOA circuit are controlled by clock signals (CKN-1, CKN, CKN+1, CKN+2) which are not attenuated, and thus, failure caused by stage transmission signal (STN, STN-1) attenuation due to threshold voltage drift of the thin film transistors can be avoided.
