Abstract: front page image
(EN)A gate drive circuit, comprising multiple stages of gate drive units, wherein each stage of gate drive unit comprises an input control module (100), an output control module (200), a pull-down module (300), a pull-down maintaining module (400) and a current compensation module (500). The current compensation module (500) effectively compensates for the potential of an output end of a gate drive unit of the present stage, thereby significantly improving the stability of a gate drive circuit and facilitating improving the display effect of a liquid crystal display panel.
(FR)L'invention concerne un circuit d'attaque de grille, comportant des étages multiples d'unités d'attaque de grille, chaque étage de unité d'attaque de grille comportant un module (100) de commande d'entrée, un module (200) de commande de sortie, un module (300) de rappel vers le bas, un module (400) de maintien de rappel vers le bas et un module (500) de compensation de courant. Le module (500) de compensation de courant compense efficacement le potentiel d'une extrémité de sortie d'une unité d'attaque de grille de l'étage actuel, améliorant ainsi significativement la stabilité d'un circuit d'attaque de grille et facilitant l'amélioration de l'effet d'affichage d'un panneau d'affichage à cristaux liquides.
