Title
(EN) TOUCHSCREEN AND OLED DISPLAY PANEL
(FR) ÉCRAN TACTILE ET PANNEAU D'AFFICHAGE À OLED
(ZH) 一种触摸屏及OLED显示面板
Abstract
(EN)
A touchscreen and a corresponding OLED panel. With a metal grid touch circuit manufactured on a packaging layer (4) of a flexible OLED display screen, and the metal grid touch circuit made to avoid light-emitting areas of pixels (7), traces run in intermediate areas between adjacent pixels (7), and at least one electrode among a driving electrode or a sensing electrode is conductively connected via a metal bridge (13) on the underside, thus implementing a flexible touchscreen, reducing the thickness thereof to that of a film by reducing the usage of a transparent optical adhesive, and reducing production costs.
(FR)
L'invention concerne un écran tactile et un panneau à OLED correspondant. Avec un circuit tactile à grille métallique fabriqué sur une couche d'encapsulation (4) d'un écran d'affichage à OLED souple, le circuit tactile à grille métallique étant fabriqué de manière à éviter des zones électroluminescentes de pixels (7), des tracés parcourent des zones intermédiaires entre des pixels (7) adjacents, et une électrode de pilotage et/ou une électrode de détection sont connectées de façon à conduire l'électricité par l'intermédiaire d'un pont métallique (13) sur le dessous. Cela permet d'obtenir un écran tactile souple, de réduire l'épaisseur de ce panneau à celle d'un film grâce à la limitation de l'usage d'un adhésif optique transparent, et de réduire les coûts de production.
(ZH)
一种触摸屏以及相应的OLED面板,通过在柔性OLED显示屏的封装层(4)上制作金属网格触控线路,并使金属网格触控线路避开像素点(7)的发光区,在相邻像素点(7)的中间区域走线,且驱动电极或感应电极至少其中一种电极通过下方的金属桥(13)连接导通,从而可以实现柔性触摸屏,并通过减少透明光学胶的使用,使其厚度变薄膜,降低生产成本。
