Title (EN) DRIVE CIRCUIT FOR LIQUID CRYSTAL PANEL, AND LIQUID CRYSTAL DISPLAY
(FR) CIRCUIT D'ATTAQUE POUR PANNEAU À CRISTAUX LIQUIDES, ET ÉCRAN À CRISTAUX LIQUIDES
(ZH) 液晶面板驱动电路及液晶显示器
Abstract:
(EN) Provided are a drive circuit for a liquid crystal panel, and a liquid crystal display. The drive circuit comprises a power integrated module (21), a timing control module (22), a compensation module (23) and a temperature sensor (24). The power integrated module (21) and the timing control module (22) perform adjustment of a low direct current voltage (VSS) or a clock signal (CLK) according to a compensation parameter, and transmit the same to a liquid crystal panel, such that an operating voltage of a TFT device in the liquid crystal panel matches an operating temperature, thereby increasing reliability of the liquid crystal panel.
(FR) Circuit d'attaque pour panneau à cristaux liquides, et écran à cristaux liquides. Le circuit d'attaque comprend un module d'alimentation intégré (21), un module de commande de temporisation (22), un module de compensation (23) et un capteur de température (24). Le module d'alimentation intégré (21) et le module de commande de temporisation (22) ajustent une faible tension continue (VSS) ou un signal d'horloge (CLK) en fonction d'un paramètre de compensation et les transmettent à un panneau à cristaux liquides, de telle sorte qu'une tension de fonctionnement d'un dispositif TFT dans le panneau à cristaux liquides soit égale à une température de fonctionnement, ce qui permet de rendre le panneau à cristaux liquides plus fiable.
(ZH) 一种液晶面板驱动电路及液晶显示器,驱动电路包括功率集成模块(21)、时序控制模块(22)、补偿模块(23)及温度传感器(24);功率集成模块(21)和时序控制模块(22)根据补偿参数对直流低电压(VSS)或者时钟信号(CLK)进行调整后再输出至液晶面板,以使液晶面板中的TFT器件的工作电压与工作温度相匹配,从而提升液晶面板的信赖性。
