Abstract:
(EN) A pixel voltage compensation method, a pixel voltage compensation device (100; 200), and a display device (300). The compensation method comprises: determining capacitance formed between at least one data line adjacent to a target pixel electrode and the target pixel electrode; detecting a voltage difference between a driving voltage on the data line and a driving voltage of the target pixel electrode in the period from the beginning of this charging of the target pixel electrode to the beginning of next charging; calculating the variable quantity of the driving voltage of the target pixel electrode caused by the capacitance and the voltage difference; and compensating for the driving voltage of the target pixel electrode according to the variable quantity. The compensation method can restrain the voltage interference phenomenon, and thus the display effect of the display device (300) can be improved.
(FR) L'invention concerne un procédé de compensation de tension de pixel, un dispositif de compensation de tension de pixel (100; 200) et un dispositif d'affichage (300). Le procédé de compensation consiste à : déterminer une capacité formée entre au moins une ligne de données adjacente à une électrode de pixel cible et l'électrode de pixel cible; détecter une différence de tension entre une tension de commande sur la ligne de données et une tension de commande de l'électrode de pixel cible durant la période allant du début de la charge de l'électrode de pixel cible au début de la charge suivante; calculer la quantité variable de la tension de commande de l'électrode de pixel cible provoquée par la capacité et la différence de tension; et compenser la tension de commande de l'électrode de pixel cible en fonction de la quantité variable. Le procédé de compensation permet de limiter le phénomène d'interférence de tension, ce qui améliore l'effet d'affichage du dispositif d'affichage (300).
(ZH) 一种像素电压补偿方法、像素电压补偿装置(100;200)和显示装置(300)。该补偿方法包括:确定与目标像素电极相邻的至少一条数据线与目标像素电极之间形成的电容;在目标像素电极本次充电开始到下一次充电开始的周期内,检测数据线上的驱动电压与目标像素电极的驱动电压的电压差;计算由电容和电压差引起的目标像素电极的驱动电压的变化量;根据变化量对目标像素电极的驱动电压进行补偿。该补偿方法能够抑制电压串扰现象,进而可以提升显示装置(300)的显示效果。
