Abstract
(EN)
A liquid crystal display module, a liquid crystal display, and a display device. The liquid crystal display module comprises a backlight module and a liquid crystal display panel arranged above the backlight module. The liquid crystal display panel comprises three display substrate layers and two liquid crystal unit layers, the three display substrate layers and two liquid crystal unit layers being alternatingly arranged. By means of controlling the first liquid crystal layer, light rays may be allowed to pass or blocked, improving the contrast ratio and dark state quality of the liquid crystal display module.

L'invention concerne un module d'affichage à cristaux liquides, un écran à cristaux liquides et un dispositif d'affichage. Le module d'affichage à cristaux liquides comprend un module de rétroéclairage et un panneau d'affichage à cristaux liquides agencé au-dessus du module de rétroéclairage. Le panneau d'affichage à cristaux liquides comprend trois couches de substrat d'affichage et deux couches d'unité à cristaux liquides, les trois couches de substrat d'affichage et les deux couches d'unité à cristaux liquides étant agencées en alternance. Au moyen de la commande de la première couche de cristaux liquides, des rayons lumineux peuvent passer ou être bloqués, améliorant le facteur de contraste et la qualité d'état sombre du module d'affichage à cristaux liquides.
