AI Technical Summary

Technical Problem

In existing 3D display technology, the low bonding accuracy between the optical substrate and the display panel leads to crosstalk between left-handed circularly polarized light and right-handed circularly polarized light during 3D display, thereby reducing the 3D display effect.

Method used

A shading layer and a light adjustment unit are set on the optical substrate, including multiple first shading areas and optical areas. The shading area is located between two adjacent rows of optical areas. By blocking crosstalk light, the fitting accuracy is improved and crosstalk is avoided.

Benefits of technology

It effectively reduces the fitting deviation between the optical substrate and the display panel, improves the viewing experience and display effect of 3D display, and enhances the picture quality and resolution.

Abstract

The utility model provides an optical substrate, a display device and a 3D display system. Relates to the technical field of display, the optical substrate comprises a transparent glass substrate, a shading layer and a light adjusting unit, the shading layer is arranged between the light adjusting unit and the transparent glass substrate, the shading layer comprises a plurality of first shading areas, the light adjusting unit comprises a plurality of optical areas, one of every two adjacent optical areas is a right-handed circularly polarized light area, and the other optical area is a right-handed circularly polarized light area. The orthographic projection of the first shading area on the transparent glass substrate is located between the two adjacent rows of optical areas. Since the first shading area is arranged between the two rows of optical areas, the first shading area can shade crosstalk light rays appearing between the two adjacent rows of optical areas, the crosstalk light rays are prevented from entering human eyes, and the display effect of 3D display is improved.
