Problems solved by technology

However, due to the lack of contrast in the current ordinary 3D glasses lenses, the light is not completely closed, and light leakage is prone to occur, resulting in ghosting when watching 3D animations.

Embodiment Construction

[0013] The present invention will be described in further detail below through specific examples.

[0014] Set the side close to the display screen as the bottom side, and the side close to the human eye as the top side.

[0015] A kind of 3D glasses lens, such as figure 1 As shown, the direction from the display screen to the external light source includes a multi-layer structure in sequence: a lower polarizer 10, a lower glass substrate 12, a lower transparent conductive film 11, a lower insulating layer 9, a lower alignment layer 8, a liquid crystal layer 7, a sealant 6, The upper alignment layer 5, the upper insulating layer 4, the upper transparent conductive film 3, the upper glass substrate 2 and the upper polarizer 1, the absorption axes of the lower polarizer 10 and the upper polarizer 1 are perpendicular to each other, and each of the liquid crystal layer 7 The liquid crystal sheets are arranged in a 90° twisted spiral.

[0016] Both the upper polarizer 1 and the l...

Abstract

The invention discloses a lens for 3D glasses. In a direction from a display screen to an external light source, the lens comprises the following multiple structures: a lower polaroid, a lower glass substrate, a lower transparent conductive film, a lower insulating layer, a lower orientation layer, a liquid crystal layer, sealing adhesive, an upper orientation layer, an upper insulating layer, anupper transparent conductive film, an upper glass substrate and an upper polaroid. The absorption axes of the upper polaroid and lower polaroid are vertical to each other, and each liquid crystal lamination of the liquid crystal layer is in 90-degree spiral arrangement. The lens for 3D glasses has the advantages of simple structure, good contrast ratio and capability of reducing light leak rate and improving viewing quality.

Description

technical field [0001] The invention relates to a lens, in particular to a 3D spectacle lens suitable for various display systems. Background technique [0002] With the continuous development of liquid crystal display technology, the application range of liquid crystal display devices is getting wider and wider. At present, 3D movies and TVs have quietly become popular. 3D technology can make the picture three-dimensional and realistic, and the image is no longer limited to the plane of the screen. Being able to step out of the screen makes the audience feel like they are there. The most basic principle is to use the left and right of the human eye to receive different images, and then the brain superimposes and regenerates the image information to form an image with three-dimensional effects such as front-back, up-down, left-right, and far-near. [0003] Active shutter 3D technology mainly achieves 3D effects by increasing the refresh rate of the screen. By dividing the i...
