Abstract
(EN)
A shift register and a driving method therefor, a gate driving circuit, and a display device. The shift register (10) can comprise a compensation selection circuit (100), a holding circuit (200) and N shift register circuits (300). The holding circuit can hold a blanking input signal. Each of the shift register circuits can comprise a blanking input circuit (310) and an output circuit (330). The blanking input circuit can provide a blanking pull-down signal to a first node (Q) according to the blanking input signal and a blanking control signal (CLKA). The output circuit can output a shift signal from a shift signal output end (CR) according to the voltage of the first node, and output a first driving signal from a first driving signal output end (OUT). The compensation selection circuit can provide the blanking input signal to the holding circuit and the N shift register circuits according to a compensation selection control signal (OE) and the shift signal outputted by one of the N shift register circuits.

L’invention concerne un registre à décalage et un procédé de pilotage correspondant, un circuit de pilotage de grille et un dispositif d’affichage. Le registre à décalage (10) peut comprendre un circuit de sélection de compensation (100), un circuit de maintien (200) et N circuits de registre à décalage (300). Le circuit de maintien peut maintenir un signal d'entrée de suppression. Chacun des circuits de registre à décalage peut comprendre un circuit d'entrée de suppression (310) et un circuit de sortie (330). Le circuit d'entrée de suppression peut fournir un signal d'excursion basse de suppression à un premier nœud (Q) en fonction du signal d'entrée de suppression et d'un signal de commande de suppression (CLKA). Le circuit de sortie peut émettre en sortie un signal de décalage en provenance d'une extrémité de sortie de signal de décalage (CR) en fonction de la tension du premier nœud, et émettre en sortie un premier signal de pilotage en provenance d'une première extrémité de sortie de signal de pilotage (OUT). Le circuit de sélection de compensation peut fournir le signal d'entrée de suppression au circuit de maintien et aux N circuits de registre à décalage en fonction d'un signal de commande de sélection de compensation (OE) et du signal de décalage émis par l'un des N circuits de registre à décalage.
