Problems solved by technology

In the above-mentioned 3D display device, the liquid crystal grating is a twisted nematic (TN) type liquid crystal grating. Since the liquid crystal grating on the light-emitting side of the display device in the above-mentioned 3D display device uses two substrates, the thickness of the above-mentioned 3D display device is relatively thick. , and the 3D display control devices used to realize the 3D display function in the liquid crystal grating on the light-emitting side of the display device in the above-mentioned 3D display device are distributed on both sides of the liquid crystal layer. Each production part is used to realize the 3D display control device of the 3D display function, and the process is relatively complicated
[0004] In summary, the 3D display devices in the prior art are relatively thick and the process is relatively complicated

Abstract

The invention provides a 3D display device and a preparation method thereof for decreasing the thickness of the 3D display device and simplifying the technology. The 3D display device comprises a display device and a liquid crystal grating arranged on the light emitting side of the display device. The liquid crystal grating comprises a substrate, a liquid crystal layer arranged between the substrate and the display device in a filled mode and a 3D display control device only located on the side, facing the liquid crystal layer, of the substrate.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a 3D display device and a manufacturing method thereof. Background technique [0002] With the continuous development of liquid crystal display technology, three-dimensional (Three Dimension, 3D) stereoscopic display technology has attracted much attention and has become an important frontier technology field in the display field. 3D stereoscopic display technology includes vision-aided 3D display and naked-eye 3D display. Among them, the naked-eye 3D display is a display that does not require any visual aid device to view the 3D effect. In naked-eye 3D display technology, 3D display devices based on liquid crystal gratings have attracted much attention due to their advantages of simple structure, compatibility with liquid crystal technology, and good performance. The 3D stereoscopic display effect is realized by using the principle, which generally includes a displa...
