Title
(EN) LIQUID CRYSTAL DISPLAY PANEL
(FR) PANNEAU D'AFFICHAGE À CRISTAUX LIQUIDES
(ZH) 一种液晶显示面板
Abstract
(EN)
Provided is a liquid crystal display panel, wherein same is defined as having a blind hole region and a display region. The liquid crystal display panel comprises a substrate layer, a gate insulating layer, a first metal layer, an interlayer insulating layer, a second metal layer, a flat layer, a pixel electrode layer, an organic layer and a common electrode layer arranged in sequence. In the blind hole region, the pixel electrode layer is downwardly recessed to be in contact with the first metal layer, and the common electrode layer is downwardly recessed to be in contact with the second metal layer. Provided is a liquid crystal display panel, in which a common electrode layer is bridged with a scanning line layer to straighten a horizontal wiring, and a pixel electrode layer is bridged with a data line layer to straighten a vertical wiring, such that the wrapping of a wire in a blind hole boundary region is eliminated or reduced, and at the same time, the requirement for the penetration of a camera module can be satisfied, and the appearance of a display screen is thus more attractive.

L'invention concerne un panneau d'affichage à cristaux liquides dans lequel celui-ci est défini comme ayant une région de trou borgne et une région d'affichage. Le panneau d'affichage à cristaux liquides comprend une couche de substrat, une couche d'isolation de grille, une première couche métallique, une couche isolante intermédiaire, une seconde couche métallique, une couche plate, une couche d'électrode de pixel, une couche organique et une couche d'électrode commune agencées en séquence. Dans la région de trou borgne, la couche d'électrode de pixel est renfoncée vers le bas pour être en contact avec la première couche métallique et la couche d'électrode commune est renfoncée vers le bas pour être en contact avec la seconde couche métallique. L'invention concerne un panneau d'affichage à cristaux liquides dans lequel une couche d'électrode commune est mise en liaison avec une couche de ligne de balayage pour redresser un câblage horizontal et une couche d'électrode de pixel est mise en liaison avec une couche de ligne de données pour redresser un câblage vertical, de telle sorte que l'enveloppement d'un câble dans une région de limite de trou borgne est éliminé ou réduit et, dans le même temps, l'exigence de pénétration d'un module de caméra peut être satisfaite et l'aspect d'un écran d'affichage est ainsi plus attractif.
