Title
(EN) DRIVE METHOD AND DEVICE FOR TOUCH DISPLAY PANEL
(FR) PROCÉDÉ ET DISPOSITIF DE COMMANDE POUR ÉCRAN TACTILE
(ZH) 触控显示面板的驱动方法及装置
Abstract
(EN)
Disclosed are a drive method and device for a touch display panel. The drive method comprises: obtaining image data of an image to be displayed; determining whether the obtained image data is a heavily loaded screen having a default polarity mode; if it is determined that the obtained image data is a heavily loaded screen having a default polarity mode, performing polarity adjustment on the image data; and driving, according to the polarity-adjusted image data, a touch display panel to perform image display, wherein the default polarity mode comprises that the polarities of image data corresponding to every two adjacent data lines are opposite, and the polarities of image data corresponding to a same data line are the same.
(FR)
L'invention concerne un procédé et un dispositif de commande destinés à un écran tactile. Le procédé de commande consiste à : obtenir des données d'image d'une image à afficher ; déterminer si les données d'image obtenues sont un écran fortement chargé comportant un mode de polarité par défaut ; s'il est déterminé que les données d'image obtenues sont un écran fortement chargé comportant un mode de polarité par défaut, mettre en oeuvre un ajustement de polarité sur les données d'image ; et commander, en fonction des données d'image à polarité réglée, un écran tactile afin de produire un affichage d'image, le mode de polarité par défaut consistant en ce que les polarités des données d'image correspondant à une ligne de données adjacente sur deux sont opposées, et les polarités des données d'image correspondant à une même ligne de données sont identiques.
