Abstract
(EN)
A shift register (10) and a driving method thereof, and a gate driving circuit (30) and display device. The shift register (10) being able to comprise a compensation selection circuit (100), a storage circuit (200), a blanking input circuit (300) and a shift register circuit (400). The compensation selection circuit (100) being configured for providing an input signal to a first node. The storage circuit (200) being configured for storing and maintaining a voltage difference between a blanking control signal terminal and the first node. The blanking input circuit (300) being configured for providing a blanking input signal to a second node. The shift register circuit (400) being configured for providing a compensation drive signal during a blanking period, and for providing a scan drive signal during a display period.

L'invention concerne un registre à décalage (10) et son procédé d'attaque, ainsi qu'un circuit d'attaque de grille (30) et un dispositif d'affichage. Le registre à décalage (10) est apte à comprendre un circuit de sélection de compensation (100), un circuit de stockage (200), un circuit d'entrée de suppression (300) et un circuit de registre à décalage (400). Le circuit de sélection de compensation (100) est configuré pour fournir un signal d'entrée à un premier nœud. Le circuit de stockage (200) est configuré pour stocker et maintenir une différence de tension entre un terminal de signal de commande de suppression et le premier nœud. Le circuit d'entrée de suppression (300) est configuré pour fournir un signal d'entrée de suppression à un second nœud. Le circuit de registre à décalage (400) est configuré pour fournir un signal d'attaque de compensation pendant une période de suppression et pour fournir un signal d'attaque de balayage pendant une période d'affichage.
