Title (EN) GOA CIRCUIT AND LIQUID CRYSTAL DISPLAY DEVICE
(FR) CIRCUIT GOA ET DISPOSITIF D’AFFICHAGE À CRISTAUX LIQUIDES
(ZH) 一种GOA电路及液晶显示器
Abstract:
(EN) Disclosed is a GOA circuit and liquid crystal display device. The GOA circuit (10) comprises a plurality of cascading GOA units (11) and a control module (12), each GOA unit (11) being for charging a corresponding horizontal scan line in a display region under the driving of a first level transmission clock signal (CK-A1), a second level transmission clock signal (CK-A2), a first control clock signal (CK-B1), and a second control clock signal (CK-B2). The control module (12) is for blocking, after the GOA circuit (10) has simultaneously charged all the horizontal scan lines, the first level transmission clock signal (CK-A1) and the second level transmission clock signal (CK-A2), such that the first control clock signal (CK-B1) and the second control clock signal (CK-B2) control gate electrode driving signals (GATE(1), GATE(M), GATE(N)) on the horizontal scan line to discharge to a predetermined power level. The above method avoids generation of an extra pulse signal on a horizontal scan line before output of a first gate electrode drive signal (GATE(1)) after the GOA circuit has simultaneously charged all the scan lines, thereby ensuring normal operation of the GOA circuit (10).
(FR) L’invention concerne un circuit GOA et un dispositif d’affichage à cristaux liquides. Le circuit GOA (10) comprend une pluralité d’unités GOA en cascade (11) et un module de commande (12), chaque unité GOA (11) étant destinée à charger une ligne de balayage horizontale correspondante dans une région d’affichage sous le pilotage d’un signal d’horloge d’émission de premier niveau (CK-A1), d’un signal d’horloge d’émission de second niveau (CK-A2), d’un premier signal d’horloge de commande (CK-B1), et d’un second signal d’horloge de commande (CK-B2). Le module de commande (12) est destiné à bloquer, après que le circuit GOA (10) a chargé simultanément toutes les lignes de balayage horizontales, le signal d’horloge d’émission de premier niveau (CK-A1) et le signal d’horloge d’émission de second niveau (CK-A2), de telle sorte que le premier signal d’horloge de commande (CK-B1) et le second signal d’horloge de commande (CK-B2) commandent des signaux de pilotage d’électrode de grille (GRILLE (1), GRILLE (M), GRILLE (N)) sur la ligne de balayage horizontale pour une décharge à un niveau d’alimentation prédéterminé. Le procédé ci-dessus évite la génération d’un signal d’impulsion supplémentaire sur une ligne de balayage horizontale avant la délivrance d’un premier signal de pilotage d’électrode de grille (GRILLE (1)) après que le circuit GOA a chargé simultanément toutes les lignes de balayage, permettant ainsi de garantir le fonctionnement normal du circuit GOA (10).
(ZH) 公开了一种GOA电路及液晶显示器。该GOA电路(10)包括多个级联的GOA单元(11)和控制模块(12),每一GOA单元(11)用于在第一级传时钟(CK-A1)、第二级传时钟(CK-A2)、第一控制时钟(CK-B1)、第二控制时钟(CK-B2)的驱动下对显示区域中对应的水平扫描线进行充电,控制模块(12)用于在GOA电路(10)对所有水平扫描线同时充电后,屏蔽第一级传时钟(CK-A1)、第二级传时钟(CK-A2),以使第一控制时钟(CK-B1)、第二控制时钟(CK-B2)控制水平扫描线上的栅极驱动信号(GATE(1),GATE(M),GATE(N))放电至预定电平。通过上述方式实现在GOA电路对所有扫描线同时充电后,避免在第一个栅极驱动信号(GATE(1))输出之前在水平扫描线上产生冗余的脉冲信号,从而保证GOA电路(10)正常工作。
