Title (EN) GOA DRIVE UNIT AND DRIVE CIRCUIT
(FR) UNITÉ D'ATTAQUE GOA ET CIRCUIT D'ATTAQUE
(ZH) 一种GOA驱动单元及驱动电路
Abstract:
(EN) Disclosed are a GOA drive unit and a drive circuit. The GOA drive unit comprises a pull-up unit, a pull-up control unit, a pull-down unit, a pull-down maintaining unit and a bootstrap capacitor. When the pull-down maintaining unit pulls down a scanning control signal and a line scanning signal of the present line and maintains same at a low electric level, a pull-down transistor of an adjacent line also pulls down a line scanning signal of an adjacent line of a previous scanning time sequence and maintains same at a low electric level. The drive unit can increase the self-repairing capability of the GOA circuit.
(FR) L'invention concerne une unité d'attaque GOA et un circuit d'attaque. L'unité d'attaque GOA comporte une unité de rappel vers le haut, une unité de commande de rappel vers le haut, une unité de rappel vers le bas, une unité de maintien de rappel vers le bas et un condensateur d'amorçage. Lorsque l'unité de maintien de rappel vers le bas rappelle vers le bas un signal de commande de balayage et un signal de balayage de ligne de la ligne courante et le maintient à un niveau électrique bas, un transistor de rappel vers le bas d'une ligne adjacente rappelle également vers le bas un signal de balayage de ligne d'une ligne adjacente d'une séquence temporelle de balayage précédente et le maintient à un niveau électrique bas. L'unité d'attaque peut accroître l'aptitude à l'autoréparation du circuit GOA.
(ZH) 公开了一种GOA驱动单元及驱动电路,该GOA驱动单元包括上拉单元、上拉控制单元、下拉单元、下拉维持单元及自举电容,邻行下拉晶体管在下拉维持单元将本行的扫描控制信号和行扫描信号拉低并维持在低电平时,将前一扫描时序的相邻行的行扫描信号也拉低并维持在低电平。该驱动单元能够增加GOA电路的自修复能力。
