Embodiment 1

[0031] Firstly, zinc oxide nanoparticles were prepared by sol-gel method; then aromatic epoxy resin acrylate oligomer, polyester type aromatic urethane acrylate oligomer, aliphatic polyester acrylate oligomer, acrylate monomer Body, zinc oxide nanoparticles, graphene, photoinitiator, and additives are mixed in a certain proportion to form a polymeric matrix; figure 1 As shown, the polymer matrix is ​​then cast-coated on the PET transparent substrate, and a pair of pressure rollers composed of a micro-gravure coating roller and a smooth roller are rolled on the rubber material to form a regular and uniform array of micro-pillar lenses. Structure, the diameter of the micro-gravure coating roller is 20-50mm, which is set according to different coating widths. For example, when the coating width is 300nm, a micro-gravure coating roller with a diameter of 20mm is used, and when the coating width is 1600mm, A micro-gravure coating roller with a diameter of 50 mm is used; the polymer...

[0051] The difference between this example and Example 1 is that the formulation of the polymer matrix is ​​changed. In this example, the formula (parts by weight) of the polymer matrix is: 42 parts of bisphenol A epoxy acrylate (brand 9104), 7 parts of polyester-type aromatic urethane acrylate oligomer (brand 6210F-80) , 8 parts of aliphatic polyester acrylic oligomer (grade 5320), 27 parts of isobornyl acrylate, 18 parts of neopentyl glycol diacrylate, 2 parts of zinc oxide nanoparticles (1-100nm), 0.001 part of graphene , 1-hydroxycyclohexyl benzophenone (photoinitiator 184) 5 parts, leveling agent (fumed silica) 1.5 parts, defoamer (organosiloxane, brand EFKA2040) 2.5 parts, wetting agent (fluorine Carbon-modified acrylate, grade EFKA3277) 1 part.

Abstract

The invention discloses a low-ghosting cylindrical lens type 3D (three-dimensional) optic sheet. The low-ghosting cylindrical lens type 3D (three-dimensional) optic sheet comprises a transparent substrate and a coating coated onto the substrate, wherein the coating is of a micro cylindrical lens array structure and is obtained through ultraviolet curing of a polymeric matrix, which comprises acrylate oligomer, acrylic monomer, graphene and zinc oxide nano-particles. The invention also relates to a preparation method of the low-ghosting cylindrical lens type 3D (three-dimensional) optic sheet. The low-ghosting cylindrical lens type 3D (three-dimensional) optic sheet has the advantages of being high in light transmittance and low in ghosting degree.

Description

technical field [0001] The invention relates to the technical field of information display, and specifically designs a cylindrical lens type 3D optical three-dimensional film with low double shadow and a preparation method thereof. Background technique [0002] In recent years, 3D movies have been favored by more and more viewers for their realistic visual experience, but it is very inconvenient to watch them with glasses. In this context, glasses-free 3D technology came into being. At present, in the naked-eye 3D display film, the lenticular 3D technology can well guarantee the brightness of the picture, and it is the most promising solution for 3D display in the future. [0003] The so-called cylindrical lens-type 3D optical three-dimensional film is made by curing acrylic resin into a micro-cylindrical lens array structure on an optical film such as PET by means of ultraviolet rays. The main function of the micro-cylindrical lens array structure is to project the sub-pi...
