Abstract
(EN)
A liquid crystal panel (200) packaged with a quantum dot layer (230) and a liquid crystal display device (300). The liquid crystal panel (200) is configured with several pixel units (231), and each of the pixel units (231) is composed of sub-pixel units in different colors; a liquid crystal layer (220) controls the backlight transmission transmitted to each sub-pixel; sub-pixel units in different colors comprise red sub-pixel units (231a) packaged with quantum dot materials, green sub-pixel units (231b), and blue sub-pixel units (231c) capable of transmitting blue backlight, wherein the surface of a package substrate packaging the pixel unit (231) at the blue sub-pixel units (231c) is configured to be a non-plane shape. When the blue light in the blue sub-pixel units (231c) is configured with a non-planar substrate, the blue light is transmitted in the non-parallel direction, the blue light, the red and green lights obtained by the excitation of the blue light and presenting dispersing lights can commonly realize the color display of the pixel unit (231), thus the color cast of each pixel unit (231) under multiple views can be solved.

L'invention concerne un panneau à cristaux liquides (200) est encapsulé avec une couche de points quantiques (230) et un dispositif d'affichage à cristaux liquides (300). Le panneau à cristaux liquides (200) est configuré avec plusieurs unités de pixel (231), et chacune des unités de pixel (231) est composée d'unités de sous-pixel dans différentes couleurs ; une couche de cristaux liquides (220) commande la transmission de rétroéclairage transmise à chaque sous-pixel ; des unités de sous-pixel dans différentes couleurs comprennent des unités de sous-pixel rouge (231a) encapsulées avec des matériaux à points quantiques, des unités de sous-pixel vert (231b) et des unités de sous-pixel bleu (231c) capable de transmettre un rétroéclairage bleu, la surface d'un substrat d'encapsulation contenant l'unité de pixel (231) au niveau des unités de sous-pixel bleu (231c) étant configurée pour être une forme non plane. Lorsque la lumière bleue dans les unités de sous-pixel bleu (231c) est configurée avec un substrat non plan, la lumière bleue est transmise dans la direction non parallèle, la lumière bleue, les lumières rouge et verte obtenues par l'excitation de la lumière bleue et la présentation de lumières de dispersion peuvent communément permettre l'affichage couleur de l'unité de pixel (231), ainsi la couleur diffusée de chaque unité de pixel (231) sous de multiples vues peut être résolue.
