Title (EN) GATE DRIVING UNIT AND DRIVING CIRCUIT
(FR) UNITÉ ET CIRCUIT DE COMMANDE DE GRILLE
(ZH) 一种栅极驱动单元及驱动电路
Abstract:
(EN) A gate driving unit and a driving circuit. The gate driving unit comprises: a pull-up control unit (110), used for generating a scanning control signal; a pull-up level transmission unit (120), used for converting a scanning clock signal into a line scanning signal; a pull-down unit (130), used for pulling the scanning control signal and the line scanning signal down to a low level; and a pull-down maintenance unit (140), used for maintaining the scanning control signal and the line scanning signal at the low level. The present invention improves the reliability of a gate driving circuit.
(FR) La présente invention concerne une unité et un circuit de commande de grille. L'unité de commande de grille comprend : une unité de commande de rappel au niveau haut (110) utilisée pour générer un signal de commande de balayage ; une unité de transmission de rappel au niveau haut (120) utilisée pour convertir un signal d'horloge de balayage en un signal de balayage de ligne ; une unité de rappel au niveau bas (130) utilisée pour rappeler au niveau bas le signal de commande de balayage et le signal de balayage de ligne ; et une unité de maintien de rappel au niveau bas (140) utilisée pour maintenir au niveau bas le signal de commande de balayage et le signal de balayage de ligne. La présente invention améliore la fiabilité d'un circuit de commande de grille.
(ZH) 一种栅极驱动单元及驱动电路,栅极驱动单元包括:上拉控制单元(110),用于生成扫描控制信号;上拉级传单元(120),用于将扫描时钟信号转化为行扫描信号;下拉单元(130),用于将扫描控制信号和行扫描信号下拉至低电平;下拉维持单元(140),用于将扫描控制信号和行扫描信号维持在低电平。增加了栅极驱动电路的可靠性。
