US 2023/0144117 A1 · GOA CIRCUIT, DISPLAY PANEL, AND REPAIR METHOD

Abstract

A gate driver on array (GOA) circuit, a display panel, and a repair method are provided. Connecting lines connecting GOA units, and grid lines disposed corresponding to disposed positions of the connecting lines albeit in a different layer from the connecting lines are included. When a short circuit or open circuit occurs in the connecting lines, by adopting one or more of methods: melting and disconnecting a part of the grid lines near a malfunction, melting and disconnecting a part of the connecting lines near the malfunction, or welding together the part of the grid lines and the part of the connecting lines, it is possible to repair the circuit by repairing or replacing the part of the connecting lines.
