Abstract
(EN) Shift register units (200, 300, 500, 600) and a driving method (900) therefor, gate driving circuits (800, 1110) and a driving method (1000) therefor, and a display device (1100). The shift register units (200, 300, 500, 600) comprise input sub-circuits (210, 310, 510, 610), discharge control sub-circuits (220, 320, 520, 620), discharge sub-circuits (230, 330, 530, 630) and output sub-circuits (240, 340, 540, 640). The input sub-circuits (210, 310, 510, 610) are configured to transmit, under the control of the voltage of a second node (PD), to a first node (PU) an input signal coming from an input signal end (IN). The discharge control sub-circuits (220, 320, 520, 620) are configured to transmit, under the control of the voltage of the first node (PU), to the second node (PD) a first clock signal coming from a first clock signal end (CLK1). The discharge sub-circuits (230, 330, 530, 630) are configured to, under the control of the voltage of the second node (PD), to a output signal end (OUT) a first constant voltage signal coming from a first constant voltage signal end (VSS). The output sub-circuits (240, 340, 540, 640) are configured to transmit, under the control of the voltage of the first node (PU), to the output signal end (OUT) a second clock signal coming from a second clock signal end (CLK2).
(FR) L'invention concerne des unités de registre à décalage (200, 300, 500, 600) et un procédé d'attaque (900) associé, des circuits d'attaque de grille (800, 1110) et un procédé d'attaque (1000) associé, et un dispositif d'affichage (1100). Les unités de registre à décalage (200, 300, 500, 600) comprennent des sous-circuits d'entrée (210, 310, 510, 610), des sous-circuits d'attaque de décharge (220, 320 520, 620), des sous-circuits de décharge (230, 330, 530, 630) et des sous-circuits de sortie (240, 340, 540, 640). Les sous-circuits d'entrée (210, 310 510, 610) sont configurés pour émettre à un premier nœud (PU), sous la commande de la tension d'un second nœud (PD), un signal d'entrée en provenance d'une extrémité de signal d'entrée (IN). Les sous-circuits de commande de décharge (220, 320, 520, 620) sont configurés pour émettre, sous le contrôle de la tension du premier nœud (PU), au second nœud (PD) un premier signal d'horloge en provenance d'une première extrémité de signal d'horloge (CLK1). Les sous-circuits de décharge (230, 330, 530, 630) sont configurés pour émettre à une extrémité de signal de sortie (OUT), sous la commande de la tension du second nœud (PD), un premier signal de tension constante en provenance d'une première extrémité de signal de tension constante (VSS). Les sous-circuits de sortie (240, 340, 540, 640) sont configurés pour émettre à l'extrémité de signal de sortie (OUT), sous la commande de la tension du premier nœud (PU), un second signal d'horloge en provenance d'une seconde extrémité de signal d'horloge (CLK2).
