Abstract
(EN)
A display device, comprising: an array substrate (1); a color film substrate (2) comprising a color resist layer (21), the color resist layer (21) comprising a red color resist (R), a green color resist (G), and a blue color resist (B); a liquid crystal layer (3) located between the array substrate (1) and the color film substrate (2); and a backlight (4) located on one side of the array substrate (1) away from the liquid crystal layer (3), the liquid crystal layer (3) having a cell gap (d) of 2.0-3.3 μm. At least the red color resist (R) and the green color resist (G) are respectively filled with luminescent materials. The backlight (4) is constructed to produce light waves having a wavelength (λ) of 200-450 nm, and the red color resist (R), the green color resist (G), and the blue color resist (B) are constructed to be able to respectively produce red light, green light, and blue light after light waves pass through corresponding color resists. The display device can reduce the liquid crystal cell gap (d), thereby improving the response speed of liquid crystals, and maintaining the normal light efficiency and transmittance of the liquid crystal layer (3).

L'invention concerne un dispositif d'affichage, comprenant : un substrat de matrice (1) ; un substrat de film de couleur (2) comprenant une couche de réserve de couleur (21), la couche de réserve de couleur (21) comprenant une réserve de couleur rouge (R), une réserve de couleur verte (G) et une réserve de couleur bleue (B) ; une couche de cristaux liquides (3) située entre le substrat de matrice (1) et le substrat de film de couleur (2) ; et un rétroéclairage (4) situé sur un côté du substrat de matrice (1) à l'opposé de la couche de cristaux liquides (3), la couche de cristaux liquides (3) ayant un espace de cellule (d) de 2,0 à 3,3 µm. Au moins la réserve de couleur rouge (R) et la réserve de couleur verte (G) sont respectivement remplies de matériaux luminescents. Le rétroéclairage (4) est construit pour produire des ondes lumineuses ayant une longueur d'onde (λ) de 200-450 nm, et la réserve de couleur rouge (R), la réserve de couleur verte (G) et la réserve de couleur bleue (B) sont construites de façon à pouvoir respectivement produire de la lumière rouge, de la lumière verte et de la lumière bleue après que les ondes lumineuses passent à travers des réserves de couleur correspondantes. Le dispositif d'affichage peut réduire l'espace de cellule (d) de cristaux liquides, améliorant ainsi la vitesse de réponse de cristaux liquides et maintenant l'efficacité lumineuse et la transmittance normales de la couche de cristaux liquides (3).
