Title (EN) GAMMA REFERENCE VOLTAGE GENERATOR, GENERATING METHOD, AND LIQUID CRYSTAL DISPLAY DEVICE
(FR) GÉNÉRATEUR DE TENSION DE RÉFÉRENCE GAMMA, PROCÉDÉ DE GÉNÉRATION ET DISPOSITIF D'AFFICHAGE À CRISTAUX LIQUIDES
(ZH) 伽马参考电压产生器、产生方法以及液晶显示装置
Abstract:
(EN) Provided are a gamma reference voltage generator, a generating method, and a liquid crystal display device. The gamma reference voltage generator comprises a timing control module (110); a programmable gamma chip (120) electrically connected to the timing control module (110); a multiplexer module (130) electrically connected to the timing control module (110) and the programmable gamma chip (120). The gamma reference voltage generator can independently control the gamma reference voltage of sub-pixel units of a liquid crystal display device, so as to improve picture display quality.
(FR) L'invention concerne un générateur de tension de référence gamma, un procédé de génération et un dispositif d'affichage à cristaux liquides. Le générateur de tension de référence gamma comprend : un module de commande de synchronisation (110) ; une puce gamma programmable (120) reliée électriquement au module de commande de synchronisation (110) ; un module multiplexeur (130) relié électriquement au module de commande de synchronisation (110) et à la puce gamma programmable (120). Le générateur de tension de référence gamma peut commander de façon indépendante la tension de référence gamma des unités de sous-pixels d'un dispositif d'affichage à cristaux liquides afin d'améliorer la qualité d'affichage d'une image.
(ZH) 一种伽马参考电压产生器、产生方法以及相应的液晶显示装置。伽马参考电压产生器包括时序控制模块(110);可编程伽马芯片(120),其电连接时序控制模块(110);多路选通模块(130),其电连接时序控制模块(110)和可编程伽马芯片(120)。该伽马参考电压产生器能够实现对液晶显示装置的亚像素单元的伽马参考电压的独立控制,进而提高画面的显示品质。
