Abstract
(EN)
A scanning drive unit (10), a scanning drive circuit (100), an array substrate (AY), and a display device. A pull-up control unit (11) in the scanning drive unit (10) receives a starting voltage (STV) to control a pull-up node (PU) to be in a high reference voltage state, and correspondingly, a received clock signal (CK) is transmitted to a scanning output end (OUT) as a scanning signal output by means of a pull-up output unit (12); a pull-down control unit (13) controls the pull-up node (PU) to be in a low reference voltage state after one scanning period and controls a pull-down node (PD) to be in the high reference voltage state; the scanning output end (OUT) is controlled to be pulled down to a low reference voltage by means of a pull-down unit (14) when the pull-down node (PD) is in the low reference voltage state, and the scanning signal is stopped to be output; and meanwhile, a drift correction unit (15) controls the pull-up node (PU) to be in the low reference voltage state according to a drift correction signal.

La présente invention concerne une unité de pilotage de balayage (10), un circuit de pilotage de balayage (100), un substrat matriciel (AY) et un dispositif d’affichage. Une unité de commande d'excursion haute (11) de l'unité de pilotage de balayage (10) reçoit une tension de démarrage (STV) permettant de commander un nœud d'excursion haute (PU) pour l'amener dans un état de haute tension de référence et, de manière correspondante, un signal d'horloge reçu (CK) est transmis à une extrémité de sortie de balayage (OUT) en tant que sortie de signal de balayage au moyen d'une unité de sortie d'excursion haute (12) ; une unité de commande d'excursion basse (13) commande le nœud d'excursion haute (PU) pour l'amener dans un état de basse tension de référence après une période de balayage et commande un nœud d'excursion basse (PD) pour l'amener dans l'état de haute tension de référence ; l'extrémité de sortie de balayage (OUT) est commandée en excursion basse à une basse tension de référence au moyen d'une unité d'excursion basse (14) lorsque le nœud d'excursion basse (PD) se trouve dans l'état de basse tension de référence, et le signal de balayage est arrêté à des fins d'émission ; et une unité de correction de dérive (15) commande dans le même temps le nœud d'excursion haute (PU) pour l'amener dans l'état de basse tension de référence conformément à un signal de correction de dérive.
