Title
(EN) LIQUID CRYSTAL DISPLAY PANEL
(FR) PANNEAU D'AFFICHAGE À CRISTAUX LIQUIDES
(ZH) 一种液晶显示面板
Abstract
(EN)
A liquid crystal display panel, having a via hole region (8) and a display region, and comprising a backlight film layer, a lower polarizer (2), a TFT layer (3), a color film substrate (4) and an upper polarizer (5) which are disposed in sequence. The backlight film layer comprises a reflective sheet, a light guide plate (12), a diffusion sheet (13), a lower light enhancement layer (14) and an upper light enhancement layer (15) which are disposed in sequence. In the via hole region (8), a single-sided black shading adhesive is attached to the lower surface of the reflective sheet. The reflective sheet comprises a first reflective sheet (111) and an upwards bent second reflective sheet (112). The second reflective sheet (112) is bent upwards to fix the backlight film layer. The black shading adhesive comprises a first black shading adhesive (61) and an upwards bent second black shading adhesive (62). The second black shading adhesive (62) is bent upwards to form a black barrier wall to shield the light guide plate (12). An entire black matrix is very narrow, which can prevent light leakage and is simple and feasible, thereby greatly reducing costs and saving on the production time.

La couche de film de rétroéclairage comprend une feuille réfléchissante, une plaque de guidage de lumière (12), une feuille de diffusion (13), une couche d'amélioration de lumière inférieure (14) et une couche d'amélioration de lumière supérieure (15) disposées en séquence. Dans la région de trou d'interconnexion (8), un adhésif d'ombrage noir unilatéral est fixé à la surface inférieure de la feuille réfléchissante. La feuille réfléchissante comporte une première feuille réfléchissante (111) et une seconde feuille réfléchissante pliée vers le haut (112). La seconde feuille réfléchissante (112) est pliée vers le haut pour fixer la couche de film de rétroéclairage. L'adhésif d'ombrage noir comprend un premier adhésif d'ombrage noir (61) et un second adhésif d'ombrage noir plié vers le haut (62). Le second adhésif d'ombrage noir (62) est plié vers le haut pour former une paroi de barrière noire pour protéger la plaque de guidage de lumière (12). Une matrice noire entière est très étroite, ce qui peut empêcher une fuite de lumière et est simple et réalisable, ce qui permet de réduire considérablement les coûts et d'économiser du temps de production.
