Title (EN) GOA CIRCUIT AND LIQUID CRYSTAL DISPLAY
(FR) CIRCUIT GOA ET ÉCRAN À CRISTAUX LIQUIDES
(ZH) 一种GOA电路及液晶显示器
Abstract:
(EN) A GOA circuit, comprising a plurality of cascaded GOA units, wherein an nth stage GOA unit comprises: a clock signal source (CLK), a constant-voltage low level source (VSS), a pull-up control module (401), a pull-up module (403), a down-transmitting module (404), a pull-down module (405), a pull-down maintaining module (406), a bootstrap capacitor (Cb) and a short-circuiting control module (402). An output end of the pull-up control module (401) is connected to the pull-up module (403), the down-transmitting module (404), the pull-down module (405), the pull-down maintaining module (406) and the bootstrap capacitor (Cb); the constant-voltage low level source (VSS) is connected to the pull-down maintaining module (406) and the pull-down module (405); the clock signal source (CLK) is connected to the pull-up module (403), the down-transmitting module (404) and the short-circuiting control module (402); and the short-circuiting control module (402) is connected to the pull-down maintaining module (406).
(FR) L'invention concerne un circuit GOA comprenant une pluralité d'unités GOA en cascade, une unité GOA de n-ième étage comprenant : une source de signal d'horloge (CLK), une source de niveau bas à tension constante (VSS), un module de commande d'excursion haute (401), un module d'excursion haute (403), un module de transmission vers le bas (404), un module d'excursion basse (405), un module de maintien d'excursion basse (406), un condensateur d'amorçage (Cb) et un module de commande de court-circuitage (402). Une extrémité de sortie du module de commande d'excursion haute (401) est connectée au module d'excursion haute (403), au module de transmission vers le bas (404), au module d'excursion basse (405), au module de maintien d'excursion basse (406) et au condensateur d'amorçage (Cb); la source de niveau bas à tension constante (VSS) est connectée au module de maintien d'excursion basse (406) et au module d'excursion basse (405); la source de signal d'horloge (CLK) est connectée au module d'excursion haute (403), au module de transmission vers le bas (404) et au module de commande de court-circuitage (402); et le module de commande de court-circuitage (402) est connecté au module de maintien d'excursion basse (406).
