3D display panel, preparation method thereof, and 3D display device

Abstract

The invention discloses a 3D display panel, a preparation method thereof, and a 3D display device. The 3D display panel comprises a 2D display panel, a first polarizer, a spacer substrate, and a polarizing layer. The first polarizer is at one side of the 2D display panel. The spacer substrate is at one side of the first polarizer opposite to the display panel, and the polarizing layer is at one side of the spacer substrate opposite to the first polarizer. The polarizing layer comprises a plurality of transparent areas and a plurality of polarizing areas, and the transparent areas and the polarizing areas are alternately arranged in parallel. Each of the polarizing areas is provided with a polarizing structure, and all polarizing structures are arranged in parallel. The first polarizer has a first polarizing shaft, the polarizing structures comprise second polarizing shafts, and the first polarizing shaft is perpendicular to the second polarizing shafts. According to the technical scheme of the invention, the naked-eye 3D display can be realized, when UV glue is used to fix the first polarizer and space glass, the solidification of each area in the UV glue can be ensured, and thus the firmness of fixation between the space glass and the display panel and the uniformity of emitted light are improved.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a 3D display panel, a preparation method thereof, and a 3D display device. Background technique [0002] The display devices used in daily life generally adopt two-dimensional display, which cannot intuitively express the depth information of the scene. With the development of computer information technology and display technology, three-dimensional display technology has become a research focus in the display field. The working principle of three-dimensional (3D) display technology is: for the same scene, the viewer’s left eye and right eye receive images respectively, and the position difference caused by the interpupillary distance between the viewer’s eyes, The retina of the right eye will show two slightly different images. This difference is called "binocular parallax". The two different images form a pair of "stereoscopic image pairs". After the fusion of the visual ...

Problems solved by technology

[0005] However, during the UV curing process of the UV glue, the UV glue located under the light-shielding pattern cannot be cured, thus affecting the firmness of the fixation between the spacer glass and the display panel, and the spacer glass and the display panel are prone to relative displacement. As a result, the parallax barrier cannot be precisely matched with the 2D display panel, and the light uniformity is poor, which affects the 3D display effect.
