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 and a control method thereof and display equipment, and belongs to the technical field of display. The display device comprises a transparent substrate and a backlight source. A liquid crystal layer is arranged between the transparent substrate and the backlight source, a grid structure is arranged on the side, close to the liquid crystal layer, of the transparent substrate, the grid structure is reused as a raster and an electrode for controlling the refractive index of the liquid crystal layer. The backlight source comprises a light guide plate and acollimating light source arranged on the side face of the light guide plate. According to the display device and the control method thereof and the display equipment, the grid structure is arranged onthe side, away from the light guide plate, of the liquid crystal layer, the grid structure is reused as the raster and the electrode for controlling the refractive index of the liquid crystal layer,and an electrode assembly and the raster do not need to be arranged in the display device. The problems that in the correlation technique, a display device is complex in structure, and light is leakedat a dark state are solved, and the effects of simplifying the overall structure of the display device and avoiding light leakage at the dark state are 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...
