Title
(EN) SHIFT REGISTER AND DRIVING METHOD THEREOF, AND DISPLAY APPARATUS
(FR) REGISTRE À DÉCALAGE ET PROCÉDÉ DE PILOTAGE ASSOCIÉ, ET APPAREIL D’AFFICHAGE
Abstract
(EN)
A shift register, a method for driving the shift register and a display apparatus are provided. The shift register includes a noise reduction control circuit and a pull-up node noise reduction circuit. The noise reduction control circuit is connected with a first clock signal terminal that receives a first clock signal, a gate drive signal output terminal that outputs a gate drive signal, a noise reduction control terminal, and a noise reduction control node. The pull-up node noise reduction circuit is connected with the noise reduction control circuit, the noise reduction control terminal, and a pull-up node.

L’invention concerne un registre à décalage, un procédé permettant de piloter le registre à décalage et un appareil d'affichage. Le registre à décalage comprend un circuit de commande de réduction de bruit et un circuit de réduction de bruit de noeud d'excursion haute. Le circuit de commande de réduction de bruit est connecté à une première borne de signal d'horloge qui reçoit un premier signal d'horloge, une borne de sortie de signal d'attaque de grille qui délivre en sortie un signal d'attaque de grille, un terminal de commande de réduction de bruit, et un noeud de commande de réduction de bruit. Le circuit de réduction de bruit de noeud d'excursion haute est connecté au circuit de commande de réduction de bruit, au terminal de commande de réduction de bruit, et à un noeud d'excursion haute.
