Title (EN) SHIFT REGISTER UNIT AND DRIVING METHOD, GATE DRIVE CIRCUIT, AND DISPLAY APPARATUS
(FR) UNITÉ DE REGISTRE À DÉCALAGE ET PROCÉDÉ DE COMMANDE, CIRCUIT DE COMMANDE DE GRILLE ET APPAREIL D'AFFICHAGE
Abstract:
(EN) A shift register unit (100, 200, 300, 300A, 300B, 400, 600) includes a first node-control circuit (11, 71) for controlling a pull-up node (PU), a second node-control circuit (12, 72) for controlling a pull-down control node (PDCN), a third node-control circuit (13, 73) for controlling a first pull-down node (PD1), a fourth node-control circuit (16, 76) for controlling a second pull-down node (PD2), a pull-up circuit (14, 74), a first pull-down circuit (15, 75), and a second pull-down circuit (17, 77). The potential level at the second pull-down node (PD2) is controlled to be low during an input phase (S1) and an output phase (S2), and inverted from the potential level at the first pull-down node (PD1) during an output-suspending phase (S3).
(FR) L'invention concerne une unité de registre à décalage (100, 200, 300, 300A, 300B, 400, 600) comprenant un premier circuit de commande de noeud (11, 71) destiné à commander un noeud élévateur (PU), un deuxième circuit de commande de noeud (12, 72) destiné à commander un noeud de commande d'abaissement (PDCN), un troisième circuit de commande de noeud (13, 73) destiné à commander un premier noeud d'abaissement (PD1), un quatrième circuit de commande de noeud (16, 76) destiné à commander un deuxième noeud d'abaissement (PD2), un circuit d'élévation (14, 74), un premier circuit d'abaissement (15, 75) et un deuxième circuit d'abaissement (17, 77). Le niveau de potentiel du deuxième noeud d'abaissement (PD2) est commandé pour être faible pendant une phase d'entrée (S1) et une phase de sortie (S2) et inversé à partir du niveau de potentiel au niveau premier noeud d'abaissement (PD1) pendant une phase de suspension de sortie (S3).
