Abstract
(EN)
Disclosed are a GOA circuit and a display panel. By changing a gate signal of a seventh thin-film transistor (NT7) in a voltage stabilization module (4), voltage control of a leakage path is realized, so that a touch screen stopping leakage path is avoided.
(FR)
L'invention concerne un circuit GOA et un écran d'affichage. En modifiant un signal de grille d'un septième transistor à couches minces (NT7) dans un module de stabilisation de tension (4), une régulation de tension d'une ligne de fuite est réalisée, de sorte à éviter qu'un écran tactile n'arrête une ligne de fuite.
(ZH)
GOA电路和显示面板,通过改变稳压模块(4)中的第七薄膜晶体管(NT7)的栅极信号,以实现对漏电路径的电压控制,从而杜绝触摸屏中停漏电路径。
