Flat cylindrical lens optical device and its manufacturing device and manufacturing method

Abstract

The invention discloses a flat lenticular optical device and a manufacturing device and a manufacturing method thereof. The flat lenticular optical device comprises a convex lenticular screen (1) and a concave lenticular screen (2). The concave face of the concave lenticular screen (2) and the convex face of the convex lenticular screen (1) are complementary; the concave face of the concave lenticular screen (2) and the convex face of the convex lenticular screen (1) are fitted and fixed. The flat lenticular optical device is flatter in surface. By adopting the manufacturing device for the flat lenticular optical device, the flat lenticular optical device can be conveniently processed, and the production efficiency is higher. The manufacturing method for the flat lenticular optical device is convenient in production, high in production efficiency and high in processing precision.

Description

technical field [0001] The invention relates to naked-eye 3D stereoscopic display technology, more specifically to a flat lenticular optical device and its manufacturing device and manufacturing method. Background technique [0002] TV has experienced the development of display from black and white to color, color to high definition. True 3D display is the ideal goal that people have been pursuing. 3D display is recognized as the next generation display technology. There are two display modes for 3D display, that is, one is for wearing 3D glasses, and the other is for not wearing 3D glasses. The display technology without wearing any auxiliary equipment (mostly refers to 3D glasses) is called naked-eye 3D display technology, which is the mainstream direction of future display development. [0003] There are many ways to realize naked-eye 3D display. At present, slit grating and lenticular lens grating are generally used as the main optical devices to realize naked-eye 3D. ...

AI Technical Summary

Problems solved by technology

[0005] 1. In order to achieve a better display effect for the product, the lenticular lens grating is generally installed facing the person, which is easier to scratch the surface of the lenticular lens grating, and because the surface of the lenticular lens grating is uneven, the surface of the lenticular lens grating is easy to fall off when placed for a long time gray and not easy to clean

If a layer of glass is added to protect the surface of the lenticular lens grating, it will not only increase the cost, but also increase the weight of the product

[0006] 2. The surface of the cylindrical mirror optical film is a curved surface structure. Generally, the existing vacuum suction cups and vacuum suction rollers cannot be attached and fixed by adsorption. At present, most of the cylindrical mirrors are attached and fixed to the glass surface manually.
