Abstract
(EN)
A driving method for a panel and a display device (1000). The driving method is: Compensating a data voltage provided by the current driving cycle for the same source line on the basis of the data voltage provided by the current driving cycle and a data voltage provided by the previous driving cycle, according to whether a polarity inversion occurs between the data voltage provided by the current driving cycle and the data voltage provided by the previous driving cycle, thereby providing the compensated data voltage to a corresponding pixel (PX). Because an adaptive compensation is performed on the data voltage in which occurs a polarity inversion, the invention can at least solve the problem of darkening the screen due to the polarity inversion, furthermore improving the display quality of a display panel (10).

L'invention concerne un procédé de pilotage pour un panneau et un dispositif d'affichage (1000). Le procédé de pilotage comprend les étapes suivantes : compenser une tension de données fournie par le cycle de pilotage en cours pour la même ligne de source en fonction de la tension de données fournie par le cycle de pilotage en cours et d'une tension de données fournie par le cycle de pilotage précédent, selon qu'une inversion de polarité se produit ou non entre la tension de données fournie par le cycle de pilotage en cours et la tension de données fournie par le cycle de pilotage précédent, ce qui fournit la tension de données compensée à un pixel correspondant (PX). Etant donné qu'une compensation adaptative est effectuée sur la tension de données dans laquelle se produit une inversion de polarité, l'invention peut au moins résoudre le problème d'assombrissement de l'écran causé par l'inversion de polarité, ce qui améliore davantage la qualité d'affichage d'un panneau d'affichage (10).

一种面板的驱动方法及显示装置(1000)。该驱动方法为:针对同一条源极线,根据当前驱动周期提供的数据电压与前一驱动周期提供的数据电压之间是否发生极性变换,而基于当前驱动周期提供的数据电压和前一驱动周期提供的数据电压来对当前驱动周期提供的数据电压进行补偿,从而将经补偿的数据电压提供给相应像素(PX)。由于对发生极性反转的数据电压进行了适应性补偿,从而至少能够解决因极性反转导致的画面变暗的问题,进而提高了显示面板(10)的显示品质。
