Embodiment Construction

[0052] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0053] The structure of a display device can be as follows figure 1 As shown, the display device may include a transparent substrate 11 , an edge-lit backlight 12 and a liquid crystal layer 13 disposed between them. Electrode assemblies 14 are arranged on both sides of the liquid crystal layer 13 , and a grating 15 is also arranged between the liquid crystal layer 13 and the side-type backlight source 12 . Wherein, the edge-lit backlight 12 may include a light source 121 and a light guide plate 122 , and the light emitted by the light source 121 can be totally reflected in the light guide plate 122 .

[0054] The electrode assembly 14 is used to control the refractive index of the liquid crystal layer 13 so that the light in the side-...

Abstract

The invention discloses a display device, a control method of the display device and a display device, belonging to the field of display technology. The display device includes: a transparent substrate and a backlight; a liquid crystal layer is arranged between the transparent substrate and the backlight, and a grid-shaped structure is arranged on the side of the transparent substrate close to the liquid crystal layer, and the grid-shaped The structure is multiplexed as a grating and an electrode for controlling the refractive index of the liquid crystal layer; the backlight source includes a light guide plate and a collimated light source arranged on the side of the light guide plate. The present invention arranges the grid-like structure on the side of the liquid crystal layer away from the light guide plate, and multiplexes the grid-like structure as a grating and an electrode for controlling the refractive index of the liquid crystal, without separately disposing the electrode assembly and the grating in the display device. The problem of relatively complicated structure of the display device and light leakage in the dark state in the related art is solved. The effect of simplifying the overall structure of the display device and avoiding light leakage in the dark state is achieved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device, a control method for the display device, and a display device. Background technique [0002] A display device is a device with a display function, which is widely used in various devices with a display function. [0003] In the related art, a display device includes a transparent substrate, an edge-type backlight source, and a liquid crystal layer disposed between the two. Two electrode assemblies are respectively arranged on both sides of the liquid crystal layer, and a grating is also arranged between the liquid crystal layer and the side-type backlight source. Among them, the two electrode components are used to control the refractive index of the liquid crystal layer so that the light in the side-type backlight can enter the liquid crystal layer, and the grating is used to adjust the angle of the light incident to the liquid crystal layer so that t...
