Three-dimensional display and manufacturing method thereof

Abstract

The invention provides a three-dimensional display and a manufacturing method thereof, wherein the three-dimensional display comprises a display panel, a liquid crystal layer, an alignment layer and an adhesion layer; the liquid crystal layer is positioned at one side (opposite to the display panel) of the display panel; the alignment layer is formed by curable resin, and is positioned at the other side of the liquid crystal layer; the alignment layer is provided with a plurality of first and second alignment regions, wherein the first and second alignment regions are staggered with one another and are parallel with one another; liquid crystal on the first and second alignment regions respectively provides first phase delay and second phase delay, and the difference between the first phase delay and the second phase delay is gamma / 2; and the adhesion layer is configured between the display panel and the liquid crystal layer, the display panel is connected with the liquid crystal layer through the adhesion layer, the pencil hardness of the alignment layer is between 1B and 4H, and the adhesion force of the adhesion layer is 50-1500gf / 25mm. The three-dimensional display provided by the invention does not have a base material which is used for bearing the liquid crystal layer, so that the integral thickness can be lowered greatly, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a display, in particular to a stereoscopic display for displaying stereoscopic images and a manufacturing method thereof. Background technique [0002] Recently, stereoscopic image display devices with improved image quality have attracted attention from various industries and are favored by most consumers. Stereoscopic display technologies can be broadly classified into glasses-type, in which viewers need to wear specially designed glasses, and naked-eye types, in which viewers directly watch with naked eyes. Glasses-type stereoscopic display can be divided into filter glasses, polarized glasses and shutter glasses. The principle of the glasses-type stereoscopic display is mainly to use the display to send left and right eye images with special information, and through the selection of the head-mounted glasses, the left and right eyes can see the left and right eye images respectively to form a stereoscopic vision.

AI Technical Summary

Problems solved by technology

[0004] However, in the structure of the conventional patterned phase retardation film, a substrate must be provided to carry the alignment layer and liquid crystal layer thereon. The arrangement of the substrate not only increases the overall thickness of the display, but also avoids affecting the display effect of the three-dimensional display. , the phase difference of the material used as the base material must be 0, and the selection of the base material will greatly increase the production cost of the stereoscopic display
