Title
(EN) DISPLAY PANEL AND PREPARATION METHOD THEREFOR
(FR) ÉCRAN D'AFFICHAGE ET SON PROCÉDÉ DE PRÉPARATION
(ZH) 显示面板及其制备方法
Abstract
(EN)
A display panel and a preparation method therefor, comprising: a base plate (1), comprising a first area and a second area connected to one another; a substrate layer (2); and a display area (3) arranged on the upper surface of the second area, the display area (3) covering part of the substrate layer (2), and a stepped area and a circuit board being formed on the part of the substrate layer (2) not covered by the display area (3); when the middle of the substrate layer (2) is bent, one end thereof is attached to the upper surface of the base plate (1) and the other end is attached to the lower surface of the base plate (1). The preparation method for the display panel comprises: a base plate (1) setting step, a substrate layer (2) preparation step, a display area (3) preparation step, a binding step, a stripping step, a cutting step, and a bending step. Bending a flexible substrate material to the back of the base plate (1) effectively narrows the bezel of the display plate and increases the screen occupation ratio.

L'invention concerne un écran d'affichage et son procédé de préparation, comprenant : une plaque de base (1), comprenant une première zone et une seconde zone reliées l'une à l'autre; une couche de substrat (2); et une zone d'affichage (3) disposée sur la surface supérieure de la seconde zone, la zone d'affichage (3) recouvrant une partie de la couche de substrat (2), et une zone étagée et une carte de circuit imprimé étant formées sur la partie de la couche de substrat (2) non couverte par la zone d'affichage (3); lorsque le milieu de la couche de substrat (2) est plié, une extrémité de celle-ci est fixée à la surface supérieure de la plaque de base (1) et l'autre extrémité est fixée à la surface inférieure de la plaque de base (1). Le procédé de préparation de l'écran d'affichage comprend : une étape de réglage de plaque de base (1), une étape de préparation de couche de substrat (2), une étape de préparation de zone d'affichage (3), une étape de liaison, une étape de décapage, une étape de découpe et une étape de pliage. Le pliage d'un matériau de substrat flexible vers l'arrière de la plaque de base (1) rétrécit efficacement le cadran de la plaque d'affichage et augmente le taux d'occupation d'écran.
