Title (EN) LIQUID CRYSTAL DISPLAY DEVICE
(FR) DISPOSITIF D'AFFICHAGE À CRISTAUX LIQUIDES
(ZH) 一种液晶显示装置
Abstract:
(EN) A liquid crystal display device comprises a quantum dot panel (300) and a backlight module (200). The backlight module (200) comprises a light emitting source (210), a light guide plate (220), and a prism layer (230). Multiple first light collimation structures (231) are disposed on a light-entry surface of the prism layer (230) at intervals. The light-entry surface of the light guide plate (220) comprises multiple second light collimation structures (221). The light-entry surface of the prism layer (230) and a light-exit surface of the light guide plate (220) are disposed opposite to each other. By means of the first light collimation structures (231) and the second light collimation structures (221), light in the vertical direction and light in the horizontal direction can be collimated, thereby alleviating the color crosstalk between pixels.
(FR) La présente invention concerne un dispositif d'affichage à cristaux liquides qui comprend un panneau à points quantiques (300) et un module de rétroéclairage (200). Le module de rétroéclairage (200) comporte une source électroluminescente (210), une plaque de guidage de lumière (220), et une couche de prisme (230). Plusieurs premières structures de collimation de lumière (231) sont disposées à intervalles sur une surface d'entrée de lumière de la couche de prisme (230). La surface d'entrée de lumière de la plaque de guidage de lumière (220) comprend plusieurs secondes structures de collimation de lumière (221). Ladite surface d'entrée de lumière de la couche de prisme (230) et une surface de sortie de lumière de cette plaque de guidage de lumière (220) sont disposées en regard l'une de l'autre. Au moyen des premières structures de collimation de lumière (231) et des secondes structures de collimation de lumière (221), la lumière dans la direction verticale et la lumière dans la direction horizontale peuvent être collimatées, ce qui permet d'atténuer la diaphonie chromatique entre des pixels.
(ZH) 一种液晶显示装置,包括量子点面板(300)和背光模组(200),该背光模组(200)包括发光光源(210)、导光板(220)与棱镜层(230),棱镜层(230)的入光面间隔设置多个第一光线准直结构(231),导光板(220)的入光面包括依次相连的多个第二光线准直结构(221),棱镜层(230)的入光面和导光板(220)的出光面相对设置。通过第一光线准直结构(231)和第二光线准直结构(221)可以准直竖直和水平方向的光线,从而改善了像素间颜色串扰问题。
