Abstract:
(EN) Provided are a gate drive circuit and display device, which resolve the technical problem in the prior art of gate drive signal being prone to output anomaly. The gate drive circuit comprises a pre-charging unit circuit, an output unit circuit, and a maintenance unit circuit; the output unit circuit comprises a first reference point (Q) and a clock signal line (CKV1); the maintenance unit circuit comprises a second reference point (P) and a maintenance signal line (CKV3, Reset), a maintenance capacitor (C3) being connected between the second reference point (P) and the maintenance signal line (CKV3, Reset).
(FR) L'invention concerne un circuit d'attaque de grille et un dispositif d'affichage, qui résolvent le problème technique dans l'état de la technique, où un signal d'attaque de grille est sujet à une anomalie de sortie. Le circuit d'attaque de grille comprend un circuit d'unité de précharge, un circuit d'unité de sortie et un circuit d'unité de maintien. Le circuit d'unité de sortie comporte un premier point de référence (Q) et une ligne de signal d'horloge (CKV1), le circuit d'unité de maintien inclut un second point de référence (P) et une ligne de signal de maintien (CKV3, Réinitialisation), un condensateur de maintien (C3) étant connecté entre le second point de référence (P) et la ligne de signal de maintien (CKV3, Réinitialisation).
(ZH) 一种栅极驱动电路及显示装置,解决了现有技术容易造成栅极驱动信号输出异常的技术问题。该栅极驱动电路包括预充电单元电路、输出单元电路和维持单元电路;输出单元电路中包括第一参考点(Q)和时钟信号线(CKV1);维持单元电路中包括第二参考点(P)和维持信号线(CKV3、Reset),第二参考点(P)与维持信号线(CKV3、Reset)之间连接有维持电容(C3)。
