Abstract
(EN)
Provided are a shift register and a driving method thereof, a gate driving circuit and a display device. The shift register (300) comprises: a pre-charging module (301); a reset module (302); a control module (303); a first pull-up module (304); a second pull-up module (305); a first pull-down module (306); and a second pull-down module (307). The shift register can realize driving of two gate lines by one shift register, reduce the number of transistors to be used, reduce circuit costs, eliminate noise at an output end of the shift register, and increase operation stability.
(FR)
L'invention concerne un registre à décalage et un procédé de pilotage associé, un circuit de pilotage de grille et un dispositif d'affichage. Le registre à décalage (300) comprend : un module de préchargement (301) ; un module de réinitialisation (302) ; un module de commande (303) ; un premier module de décalage vers le haut (304) ; un second module de décalage vers le haut (305) ; un premier module de décalage vers le bas (306) ; un second module de décalage vers le bas (307). Le registre à décalage peut effectuer un pilotage de deux lignes de grille par un seul registre à décalage, peut réduire le nombre de transistors à utiliser et les coûts du circuit, peut éliminer un bruit au niveau d'une extrémité de sortie du registre à décalage et accroître la stabilité du fonctionnement.
