Abstract
(EN) Disclosed are a driving method and driving apparatus for a display panel. The polarities of adjacent sub-pixels in a row direction in a display array in the display panel of the present application are different, and the polarities of the adjacent sub-pixels in a column direction are different; the voltage strength of the adjacent sub-pixels is different, and adjacent pixels are alternately arranged in a high-low voltage intensity mode; the driving apparatus takes two frames of operation pictures of the display panel as a driving period to perform periodic change on a common voltage needed by each frame of operation picture, and different common voltages are correspondingly used for driving the sub-pixels in the display array in different frames, so that the probability of the phenomenon of viewing angle color cast of the display panel can be reduced.
(FR) La présente invention concerne un procédé de pilotage et un appareil de pilotage pour un panneau d'affichage. Les polarités de sous-pixels adjacents dans une direction de rangée dans un réseau d'affichage dans le panneau d'affichage selon la présente invention sont différentes, et les polarités des sous-pixels adjacents dans une direction de colonne sont différentes ; la résistance à la tension des sous-pixels adjacents est différente, et des pixels adjacents sont disposés en alternance dans un mode d'intensité de tension élevée-faible ; l'appareil de pilotage prend deux trames d'images de fonctionnement du panneau d'affichage en tant que période de pilotage pour effectuer un changement périodique sur une tension commune nécessaire par chaque trame d'image de fonctionnement, et différentes tensions communes sont utilisées de manière correspondante pour piloter les sous-pixels dans le réseau d'affichage dans différentes trames, de telle sorte que la probabilité du phénomène de diffusion de couleur d'angle de visualisation du panneau d'affichage peut être réduite.
(ZH) 本申请公开了一种显示面板的驱动方法、驱动装置,本申请显示面板中的显示阵列中行方向上相邻的子像素的极性不同,列方向上相邻的子像素的极性不同,相邻的子像素的电压强度不同,相邻像素互为高低电压强度穿插排列,驱动装置以显示面板的两帧运行画面为一驱动周期,对每帧运行画面中需要的共电电压进行周期性改变,不同帧中对应采取不同共电电压对显示阵列中的子像素进行驱动,能够在减少显示面板视角色偏的现象出现的几率。
