Problems solved by technology

[0006] CN101655571A discloses a method for making a lenticular grating, wherein the cylindrical strip is a mould, and the whole mold is composed of several separate molds (cylindrical strips), and the production time is also very long. The standard is also very high, the work efficiency is low, and the quality stability of the manufactured lenticular lens grating is poor, and the precision is low
Each parallax map is arranged on the LCD screen according to certain rules, but the resolution of the LCD screen is fixed, and the resolution of each parallax map is low, resulting in low resolution and unclear 3D images seen by human eyes.

Abstract

The invention discloses a preparation method of a lenticular glass grating, which comprises the steps that ultraviolet irradiation is cured after coating an ultraviolet light curing adhesive on a glass substrate; the processed glass substrate is heated to a temperature between the ultraviolet light curing adhesive glass transition temperature and the melting temperature, a mold is coated on the surface of the ultraviolet light curing adhesive, and the clearance of the mold is enabled to be filled with the ultraviolet light curing adhesive; then the temperature drops below the glass transition temperature, the mold is removed, and the ultraviolet light curing adhesive forms a cylindrical rectangular array on the surface of the glass substrate; and the glass substrate is placed in a constant-temperature device, the temperature rises above the ultraviolet light curing adhesive melting temperature and maintains for a period of time, the ultraviolet light curing adhesive is changed into a cylindrical circular-arc-shaped array, then the temperature drops below the glass transition temperature and maintains for a period of time, and the lenticular glass grating is acquired after the ultraviolet light curing adhesive is cured. The preparation method disclosed by the invention is simple to operate, low in production cost and wide in production application range. The lenticular glass grating is smooth in surface, high in precision and good in uniformity.

Description

technical field [0001] The invention belongs to the field of grating manufacture, in particular to a method for manufacturing a lenticular glass grating. Background technique [0002] At present, the production process of lenticular gratings is becoming more and more mature and diverse, especially the process of making lenticular gratings with UV-curable adhesives has attracted more and more attention and development. UV-curable adhesives are composed of prepolymers, active monomers, photoinitiators The main components are composed of stabilizers, leveling agents and other additives. Under the irradiation of ultraviolet light of appropriate wavelength, the photoinitiator rapidly generates free radicals or ions, and initiates the polymerization and crosslinking of the prepolymer and the active monomer to form a cured film. It is widely used because of its simple processing, fast curing speed, high production efficiency, high light transmittance of cured film, low shrinkage r...
