(ZH) 一种显示装置
Abstract
(EN)
A display device, comprising an optical film (200), and a light guide backplane (300) that is a light guide plate and a backplane integrated into one body. A surface of the light guide backplane (300) facing away from the optical film (200) is covered with a reflective film (400). The arrangement of the backplane in the prior art is omitted, and the thickness of components of the display device is reduced in circumstances in which the material breakthrough is not obtained so as to further reduce the thickness of the display device.
(FR)
L'invention concerne un dispositif d'affichage comprenant un film optique (200) et un fond de panier de guidage de lumière (300) qui est une plaque de guidage de lumière et un fond de panier intégré dans un corps. Une surface du fond de panier de guidage de lumière (300) opposée au film optique (200) est recouverte d'un film réfléchissant (400). L'agencement du fond de panier dans l'état de la technique est omis et l'épaisseur des composants du dispositif d'affichage est réduite dans des circonstances dans lesquelles la percée de matériau n'est pas obtenue de façon à réduire davantage l'épaisseur du dispositif d'affichage.
