Abstract
(EN)
Provided are a grating substrate (10), a display substrate, a display device and a display method thereof, belonging to the technical field of display. The grating substrate (10) includes: a first base substrate (101) and a plurality of grating units (102) located on the first base substrate (101). The grating unit (102) includes two control layers (1022, 1023), a blocking structure (1021) located between the two control layers (1022, 1023), and a plurality of movable particles (M) located in a closed cavity (Q) surrounded by the blocking structure (1021) and two control layers (1022, 1023). The two control layers (1022, 1023) include a first control layer (1022) and a second control layer (1023). The first control layer (1022) is located on the side of the second control layer (1023) away from the first base substrate (101). The two control layers (1022, 1023) are used to control the movement of the plurality of particles (M). Wherein, the particles (M) satisfy at least one of the following: the refractive index of the particles (M) is less than the refractive index of the first control layer (1022); the particles (M) are non-transparent particles. The grating substrate (10) realizes the switching between the horizontal and vertical directions of the grating, thus can realize the 3D display effect of the display substrate in different directions, improving the flexibility of the 3D display.

L'invention concerne un substrat de réseau (10), un substrat d'affichage, un dispositif d'affichage et un procédé d'affichage associé appartenant au domaine technique de l'affichage. Le substrat de réseau (10) comporte un premier substrat de base (101) et une pluralité d'unités de réseau (102) situées sur le premier substrat de base (101). L'unité de réseau (102) comprend deux couches de commande (1022, 1023), une structure de blocage (1021) située entre les deux couches de commande (1022, 1023), et une pluralité de particules mobiles (M) situées dans une cavité fermée (Q) entourée par la structure de blocage (1021) et les deux couches de commande (1022, 1023). Les deux couches de commande (1022, 1023) comprennent une première couche de commande (1022) et une seconde couche de commande (1023). La première couche de commande (1022) est située sur le côté de la seconde couche de commande (1023) à l'opposé du premier substrat de base (101). Les deux couches de commande (1022, 1023) sont utilisées pour commander le mouvement de la pluralité de particules (M). Les particules (M) satisfait à au moins l'un des éléments suivants entre l'indice de réfraction des particules (M) étant inférieur à l'indice de réfraction de la première couche de commande (1022) ; et les particules (M) étant des particules non transparentes. Le substrat de réseau (10) réalise la commutation entre les directions horizontale et verticale du réseau, ce qui permet de réaliser l'effet d'affichage 3D du substrat d'affichage dans différentes directions, améliorant la flexibilité de l'affichage 3D.
