Title
(EN) LIQUID CRYSTAL PANEL AND GATE DRIVING CIRCUIT THEREOF
(FR) PANNEAU À CRISTAUX LIQUIDES ET CIRCUIT DE COMMANDE DE GRILLE ASSOCIÉ
(ZH) 液晶面板及其栅极驱动电路
Abstract
(EN)
A gate driving circuit (100) and a liquid crystal panel (200) having the gate driving circuit (100). The gate driving circuit (100) comprises: multiple shift registers (10, 11, , 1n), each of the shift registers (10, 11, , 1n) comprising a forward-reverse gear module (1), a low potential line (VGL) and a synchronization module (2); the forward-reverse gear module (1) has an up-to-down signal input port (U2D) and a down-to-up signal input port (D2U), the forward-reverse gear module (1) controls the scanning order of the multiple shift registers (10, 11, ..., 1n) according to the signals of the up-to-down signal input port (U2D) and the down-to-up signal input port (D2U), and the synchronization module (2) is used for connecting the low potential line (VGL) to one port with a lower potential of the up-to-down signal input port (U2D) and the down-to-up signal input port (D2U).
(FR)
L'invention concerne un circuit de commande de grille (100) et un panneau à cristaux liquides (200) ayant le circuit de commande de grille (100). Le circuit de commande de grille (100) comprend : de multiples registres à décalage (10, 11, , 1n), chacun des registres à décalage (10, 11, , 1n) comprenant un module de marche avant-arrière (1), une ligne basse tension (VGL) et un module de synchronisation (2) ; le module de marche avant-arrière (1) a un port d'entrée de signal haut-bas (U2D) et un port d'entrée de signal bas-haut (D2U), le module de marche avant-arrière (1) commande l'ordre de balayage des registres à décalage multiples (10, 11, ..., 1n) en fonction des signaux du port d'entrée de signal haut-bas (U2D) et du port d'entrée de signal bas-haut (D2U), et le module de synchronisation (2) est utilisé pour connecter la ligne basse tension (VGL) à un port avec un potentiel inférieur du port d'entrée de signal haut-bas (U2D) et du port d'entrée de signal bas-haut (D2U).
