Abstract:
(EN) A touch control display panel (10, 301) driving method, driving device (100, 200, 302) and a touch control display (300), the driving method comprising: detecting voltage levels (V1) of pixel electrodes in a plurality of regions corresponding to different touch control scanning areas (20) respectively on a touch control display panel (10, 301) (S11); performing negation on the voltage levels (V1), superposing the negated voltage levels (V1) and a touch control pulse signal (V2) that is fed back, and using the superposed signal as a detected touch control pulse signal (V2) (S12). By means of said driving method, the voltage levels (V1) of the pixel electrodes in each region are utilized to respectively adjust touch control pulse signals (V2) that are fed back according to the touch control scanning areas (20) on the touch control display panel (10, 301) so that display scanning and touch control scanning may be simultaneously carried out, thereby allowing for improvement in accuracy of touch control pulse signal (V2) detection on the premise of display quality not being affected.
(FR) L’invention concerne un procédé de commande de panneau d'affichage à commande tactile (10, 301), un dispositif de commande (100, 200, 302) et un dispositif d'affichage à commande tactile (300), ledit procédé de commande consistant à : détecter des niveaux de tension (V1) d'électrodes de pixels dans une pluralité de zones correspondant respectivement aux différentes zones de balayage de commande tactile (20) sur un panneau d'affichage à commande tactile (10, 301) (S11) ; effectuer une invalidation sur les niveaux de tension (V1), superposer les niveaux de tension invalidés (V1) et un signal d'impulsion de commande tactile (V2) qui est renvoyé, puis utiliser le signal superposé comme signal d'impulsion de commande tactile détecté (V2) (S12). À l’aide dudit procédé de commande, les niveaux de tension (V1) des électrodes de pixels dans chaque zone sont utilisés pour adapter respectivement les signaux d'impulsion de commande tactile (V2) qui sont renvoyés en fonction des zones de balayage de commande tactile (20) sur le panneau d'affichage à commande tactile (10, 301) de façon à pouvoir effectuer simultanément un balayage d'affichage et un balayage de commande tactile, ce qui permet d'améliorer la précision de détection des signaux d'impulsion de commande tactile (V2) en partant du principe que la qualité d'affichage n'est pas affectée.
(ZH) 一种触控显示面板(10,301)的驱动方法、驱动装置(100,200,302)以及触控显示器(300),该驱动方法包括:检测触控显示面板(10,301)上分别与不同触控扫描分区(20)对应的多个区域内像素电极的电压准位(V1)(S11);对电压准位(V1)取反,并将取反后的电压准位(V1)与反馈的触控脉冲信号(V2)叠加,将叠加后的信号作为检测到的触控脉冲信号(V2)(S12)。通过该驱动方法,按照触控显示面板(10,301)上的触控扫描分区(20),利用各个区域内像素电极的电压准位(V1),分别对反馈的触控脉冲信号(V2)进行调整,使显示扫描和触控扫描可以同时进行,能够在不影响显示质量的前提下,提高触控脉冲信号(V2)检测的准确度。
