Title (EN) METHOD FOR DRIVING LIQUID CRYSTAL DISPLAY PANEL, AND VOLTAGE ADJUSTMENT CIRCUIT
(FR) PROCÉDÉ DE COMMANDE D'UN PANNEAU D'AFFICHAGE À CRISTAUX LIQUIDES, ET CIRCUIT DE RÉGLAGE DE TENSION
(ZH) 一种液晶显示面板的驱动方法以及电压调整电路
Abstract:
(EN) A method for driving a liquid crystal display panel, and a voltage adjustment circuit. The method comprises: acquiring a voltage (VSS2, VSS3) to be adjusted and a pre-set voltage (VSS1); when the voltage (VSS2, VSS3) to be adjusted is greater than the pre-set voltage (VSS1), calculating a first difference value (V1) between the voltage (VSS2, VSS3) to be adjusted and the pre-set voltage (VSS1); determining whether the first difference value (V1) is greater than a reference voltage (Vref); and if the first difference value (V1) is greater than the reference voltage (Vref), reducing the voltage (VSS2, VSS3) to be adjusted.
(FR) L'invention concerne un procédé de commande d'un panneau d'affichage à cristaux liquides et un circuit de réglage de tension. Le procédé comprend les étapes consistant : à acquérir une tension (VSS2, VSS3) à régler et une tension (VSS1) prédéfinie ; lorsque la tension (VSS2, VSS3) à régler est supérieure à la tension (VSS1) prédéfinie, à calculer une première valeur de différence (V1) entre la tension (VSS2, VSS3) à régler et la tension (VSS1) prédéfinie ; à déterminer si la première valeur de différence (V1) est supérieure à une tension de référence (Vref) ; et, si la première valeur de différence (V1) est supérieure à la tension de référence (Vref), à réduire la tension (VSS2, VSS3) à régler.
(ZH) 一种液晶显示面板的驱动方法以及电压调整电路,方法包括:获取待调整电压(VSS2,VSS3)和预设电压(VSS1);当待调整电压(VSS2,VSS3)大于预设电压(VSS1)时,计算待调整电压(VSS2,VSS3)与预设电压(VSS1)之间的第一差值(V1);判断第一差值(V1)是否大于参考电压(Vref);若第一差值(V1)大于参考电压(Vref),则将待调整电压(VSS2,VSS3)调小。
