Title
(EN) TOUCH CONTROL PANEL AND MANUFACTURING METHOD THEREFOR
(FR) PANNEAU DE COMMANDE TACTILE ET SON PROCÉDÉ DE FABRICATION
(ZH) 触控面板及其制造方法
Abstract
(EN)
A touch control panel and a manufacturing method therefor, belonging to the technical field of display driving. The touch control panel comprises: a touch control driver (2); multiple touch control signal lines (3), connected to the touch control driver (2); a common electrode layer, comprising multiple common electrodes (4) arranged in an array, wherein each common electrode (4) and at least one touch control signal line (3) communicate with each other correspondingly, the common electrode (4) has at least one opening (5), and the opening (5) is located at an overlapping portion of the common electrode (4) and the touch control signal line (3). The present invention reduces the area of a distal common electrode (4) by means of unevenly excavating openings (5) of the common electrode (4) at different positions in a pixel area (6) so as to realize capacitance matching, thereby preventing, when a screen size is relatively large and the load difference between a proximal end and a distal end is relatively large, the phenomenon of a poor picture quality of the product quality from occurring.

La présente invention concerne un panneau de commande tactile et son procédé de fabrication, relevant du domaine technique de la commande d'affichage. Le panneau de commande tactile comprend : un pilote de commande tactile (2); de multiples lignes de signal de commande tactile (3), connectées au pilote de commande tactile (2); une couche d'électrode commune, comprenant de multiples électrodes communes (4) agencées dans un réseau, chaque électrode commune (4) et au moins une ligne de signal de commande tactile (3) communiquant l'une avec l'autre de manière correspondante, l'électrode commune (4) ayant au moins une ouverture (5), et l'ouverture (5) étant située au niveau d'une partie de chevauchement de l'électrode commune (4) et de la ligne de signal de commande tactile (3). La présente invention réduit la surface d'une électrode commune distale (4) au moyen de l'excavation irrégulière d'ouvertures (5) de l'électrode commune (4) à différentes positions dans une zone de pixel (6) de façon à réaliser une adaptation de capacité, ce qui permet d'éviter, lorsqu'une taille d'écran est relativement grande et que la différence de charge entre une extrémité proximale et une extrémité distale est relativement grande, le phénomène de mauvaise qualité d'image de la qualité de produit.

一种触控面板及其制造方法,属于显示驱动的技术领域,包括:触控驱动器(2);多根触控信号线(3),连接至触控驱动器(2);公共电极层,包括阵列排布的多个公共电极(4),每个公共电极(4)和至少一根触控信号线(3)对应连通;其中,公共电极(4)具有至少一个开口(5),开口(5)位于公共电极(4)与触控信号线(3)的重叠部位。通过将公共电极(4)在像素区域(6)的不同位置进行不均等挖除开口(5),减小了远端公共电极(4)的面积来实现电容匹配,从而避免了当屏幕尺寸较大时,近远端负载差异较大,使产品品质出现画质不良现象的发生。
