Abstract
(EN)
Provided are a gate driving circuit and a driving method thereof, and a display device. The gate driving circuit comprises N gate driving units and N sets of clock signal lines, wherein the nth gate driving unit is correspondingly connected to the nth set of clock signal lines, N is an integer greater than 1, and n is a positive integer less than or equal to N. Each set of clock signal lines include 2a clock signal lines, where a is equal to 1 or a is an even number. Each gate driving unit comprises at least one shift register module. The shift register of the nth gate driving unit is connected to the nth set of clock signal lines. The invention effectively solves a technical problem in which clock signal lines in traditional gate driving circuits have high power consumption.

L'invention concerne un circuit d'attaque de grille et un procédé d'attaque correspondant, et un dispositif d'affichage. Le circuit d'attaque de grille comprend N unités d'attaque de grille et N ensembles de lignes de signal d'horloge, la nième unité d'attaque de grille étant connectée de manière correspondante au nième ensemble de lignes de signal d'horloge, N étant un nombre entier supérieur à 1, et n étant un nombre entier positif inférieur ou égal à N. Chaque ensemble de lignes de signal d'horloge comprend 2a lignes de signal d'horloge, a étant égal à 1 ou a étant un nombre pair. Chaque unité d'attaque de grille comprend au moins un module de registre à décalage. Le registre à décalage de la nième unité d'attaque de grille est connecté au nième ensemble de lignes de signal d'horloge. L'invention permet de résoudre efficacement le problème technique d'une forte consommation d'énergie des lignes de signal d'horloge dans des circuits d'attaque de grille classiques.
