3D display layer and 3D display structure thereof

Abstract

The invention provides a 3D display layer and a 3D display structure thereof, and belongs to the technical field of image display. The 3D display structure is configured on a display module. The 3D display layer comprises a substrate structure, a 3D optical structure and a glue layer. The substrate structure has a first surface and a second surface. The 3D optical structure is formed on the first surface of the substrate structure. The 3D optical structure comprises a plurality of lenses, the top part of each lens protrudes towards a first direction, and each lens has a curved surface. The glue layer cover the curved surface of each lens, and the glue layer is connected with a light transmission layer and the 3D optical structure. The difference of the refractive indexes of the glue layer and the 3D optical structure is larger than a preset difference value, a thickness of the glue layer is larger than a protruding height of the each lens, and the viscosity of the glue layer is larger than a preset viscosity. According to the invention, the glue layer covers each cylindrical lens, so that the problems that impurities such as oil stains and dust are accumulated in the concave-convex gaps of the cylindrical lenses and the cylindrical lenses are used as surfaces in the prior art are solved.

Description

technical field [0001] The invention relates to a 3D display layer and a 3D display structure thereof, belonging to the technical field of image display. Background technique [0002] The conventional naked-view 3D principle is to change the direction of light travel based on the light-gathering and refraction principles. The left and right eyes of the viewer see different pictures in the set area where the image light is concentrated, so as to achieve a 3D stereoscopic vision experience. The existing naked-view 3D liquid crystal display system is a general 2D flat display liquid crystal display combined with a 3D display layer, 3D display film or 3D display panel. The eyes of the viewer in the viewing area may receive different images, and these images have parallax, so a 3D stereoscopic image can be synthesized in the brain of the viewer. [0003] However, the lenticular lenses of the 3D display layer are, for example, straight strips, and these lenticular lenses are clos...

AI Technical Summary

Problems solved by technology

Among them, after the materials forming these lenticular lenses are cured by exposure to ultraviolet light, these lenticular lenses often have problems such as insufficient hardness, scratch resistance or abrasion resistance.

Furthermore, because of the concavo-convex gaps of these lenticular lenses, impurities such as oil and dust are easy to accumulate, thereby changing the refractive index of the 3D display structure and reducing the 3D display effect.
