Title
(EN) GATE DRIVING CIRCUIT AND ARRAY SUBSTRATE
(FR) CIRCUIT DE COMMANDE DE GRILLE ET SUBSTRAT DE RÉSEAU
(ZH) 栅极驱动电路及阵列基板
Abstract
(EN)
Provided are a gate driving circuit and an array substrate. The gate driving circuit comprises a plurality of shift registers (10), each of the shift registers (10) comprising a pull-up control unit (1), a pull-up unit (2), a signal download unit (3), a first pull-down unit (4), a second pull-down unit (4') and a pull-down maintaining unit (5). The first pull-down unit (4) is electrically connected to a second gate signal output port (G(N+2)), the second pull-down unit (4') is electrically connected to a third gate signal output port (G(N+3)), and a signal of the third gate signal output port G(N+3) is later than a signal of the second gate signal output port (G(N+2)).
(FR)
L'invention porte sur un circuit de commande de grille et un substrat de réseau. Le circuit de commande de grille comprend une pluralité de registres à décalage (10), chacun des registres à décalage (10) comprenant une unité de commande d'excursion haute (1), une unité d'excursion haute (2), une unité de téléchargement de signal (3), une première unité d'excursion basse (4), une seconde unité d'excursion basse (4') et une unité de maintien d'excursion basse (5). La première unité d'excursion basse (4) est connectée électriquement à un deuxième port de sortie du signal de porte (G(N+2)), la seconde unité déroulante (4') est connectée électriquement à un troisième port de sortie du signal de porte (G(N+3)), et un signal du troisième port de sortie du signal de grille G(N+3) est postérieur à un signal du deuxième port de sortie du signal de porte (G(N+2)).
