Abstract
(EN)
A display panel and a display device. The display panel comprises: a first display sub-panel (100) for controlling backlight; a second display sub-panel (200) for displaying an image, wherein the second display sub-panel (200) is located at a light-emergent side of the first display sub-panel (100); and a quantum dot layer (30) located between the first display sub-panel (100) and the second display sub-panel (200). Light emitted from the first display sub-panel (100) excites the quantum dot layer (30), and provides backlight for the second display sub-panel (200). Quantum dot materials in the quantum dot layer (30) emit stimulated-emitted light rays to the surroundings at various angles, the original propagation direction of the light rays is changed, and therefore, the light rays generated thereby can better damage a pattern generated by a periodic grating structure, thereby removing moiré fringes.

L'invention concerne un écran d’affichage et un dispositif d’affichage. L'écran d'affichage comprend : un premier sous-écran d'affichage (100) pour commander un rétroéclairage ; un second sous-écran d'affichage (200) pour afficher une image, le second sous-écran d'affichage (200) étant situé au niveau d'un côté d'émergence de lumière du premier sous-écran d'affichage (100) ; et une couche de points quantiques (30) située entre le premier sous-écran d'affichage (100) et le second sous-écran d'affichage (200). La lumière émise par le premier sous-écran d'affichage (100) excite la couche de points quantiques (30), et fournit un rétroéclairage pour le second sous-écran d'affichage (200). Des matériaux à points quantiques dans la couche de points quantiques (30) émettent des rayons lumineux émis stimulés vers l'environnement à différents angles, la direction de propagation d'origine des rayons lumineux est modifiée, et par conséquent, les rayons lumineux générés peuvent ainsi mieux endommager un motif généré par une structure de réseau périodique, ce qui permet d'éliminer les franges de moiré.

一种显示面板及显示装置,包括:第一显示子面板(100),用于控制背光;第二显示子面板(200),用于图像显示;第二显示子面板(200)位于第一显示子面板(100)出光侧;量子点层(30),位于第一显示子面板(100)和第二显示子面板(200)之间。第一显示子面板(100)的出射光激发量子点层(30),为第二显示子面板(200)提供背光。由于量子点层(30)中的量子点材料受激发射的光线以各个角度向四周发射,改变光线原本的传播方向,因此其产生的光线可以较好地破坏周期性光栅结构产生的图形,从而消除莫尔条纹。
