(EN)
A touch display panel and a detection method therefor, and a display device. A common electrode layer is segmented into multiple self-capacitance electrodes (051) that are independent from one another, so that a common electrode is reused as the self-capacitance electrodes (051). The touch display panel also comprises a compensation electrode (07) that is arranged on a different layer from the self-capacitance electrodes (051) and insulated from the self-capacitance electrodes (051) and at least covers segmentation gaps between some adjacent self-capacitance electrodes (051). The compensation electrode (07) is used for loading a common electrode signal in the display time period. Therefore, during display, common electrode signals at segmentation gaps of the self-capacitance electrodes (051) can be compensated by the common electrode signal loaded on the compensation electrode (07), so that normal turning of liquid crystals at the segmentation gaps is guaranteed, and normal display of the whole display panel is guaranteed.

La présente invention concerne un panneau d'affichage tactile et son procédé de détection, ainsi qu'un dispositif d'affichage. Une couche d'électrode commune est segmentée en de multiples électrodes à capacitance propre (051) qui sont indépendantes les unes des autres, de sorte qu'une électrode commune soit réutilisée en tant qu'électrode à capacitance propre (051). Le panneau d'affichage tactile comprend également une électrode de compensation (07) qui est disposée sur une couche différente des électrodes à capacitance propre (051) et isolée des électrodes à capacitance propre (051) et recouvre au moins des espaces de segmentation entre certaines électrodes à capacitance propre (051) adjacentes. L'électrode de compensation (07) est utilisée pour charger un signal d'électrode commune pendant la période d'affichage. Par conséquent, pendant l'affichage, des signaux d'électrode commune au niveau d'espaces de segmentation des électrodes à capacitance propre (051) peuvent être compensés par le signal d'électrode commune chargé sur l'électrode de compensation (07), de sorte que la rotation normale des cristaux liquides au niveau des espaces de segmentation soit garantie, et que l'affichage normal de la totalité du panneau d'affichage soit garanti.

一种触摸显示面板、其检测方法及显示装置,公共电极层被分割成多个相互独立的自电容电极(051),利用公共电极复用为自电容电极(051),还包括与自电容电极(051)异层且绝缘设置、且至少覆盖部分相邻自电容电极(051)之间的分割间隙的补偿电极(07),补偿电极(07)用于在显示时间段加载公共电极信号。这样在显示时,利用在补偿电极(07)上加载的公共电极信号可以补偿自电容电极(051)分割间隙处的公共电极信号,从而保证分割间隙处液晶正常翻转,保证整个显示面板显示正常。
