Embodiment Construction

[0012] see figure 1 , is an optical element 100 provided by an embodiment of the present invention, which includes a transparent substrate 10 , a transparent optical film 20 and a transparent adhesive layer 30 . The surface of the optical film 20 facing away from the substrate 10 has a microstructure pattern 21 .

[0013] The material of the base material 10 is an organic polymer, and the optical film 20 is obtained by curing UV glue including monomers of the organic polymer. In this embodiment, the material of the substrate 10 is polymethylmethacrylate (PMMA), which is referred to as acrylic resin for short. The optical film 20 is formed by curing UV glue containing PMMA monomer (PMMA UV glue for short). Because PMMA UV glue includes PMMA monomers and photoinitiators, the photoinitiators generate active free radicals or cations after absorbing ultraviolet light under the irradiation of ultraviolet rays, triggering the chemical reactions of polymerization, crosslinking and b...

Abstract

The invention relates to an optical element and a manufacturing method thereof. The optical element includes a transparent base material and a transparent optical film which is formed on the base material. A surface, which is opposite to the base material, of the optical film is provided with micro-structure patterns. The base material is prepared from an organic polymer. The optical film is prepared from an ultraviolet glue of a monomer containing the organic polymer in a curing manner. The invention also relates to the manufacturing method of the optical element.

Description

technical field [0001] The invention relates to an optical element and a manufacturing method thereof. Background technique [0002] Optical elements (such as diffuser plates, light guide plates, etc.) in current backlight modules are generally manufactured by roller embossing. In the roller embossing method, a forming roller with an embossing pattern needs to be used to form a microstructure pattern on the optical element. The embossed pattern on the current forming roller is generally produced by laser processing. However, after laser processing, crater-shaped molten metal bumps will be formed around the processed embossing pattern, affecting the flatness of the surface of the forming roller, thereby affecting the product yield of the optical element. Contents of the invention [0003] In view of this, it is necessary to provide an optical element and a manufacturing method thereof, which can effectively improve product yield. [0004] An optical component includes a ...
