Abstract
The invention discloses an optical diffusion barrier comprising a transparent base material layer. A side of the transparent base material layer is coated with a diffusion coating filled with diffusion particles. The other side of the transparent base material layer is provided with an anti-bonding layer with an uneven surface. The optical diffusion barrier solves a problem that the diffusion particles are liable to fall, and has advantages of simple structure and manufacture technology and excellent performance.
Description
Technical field
The present invention relates to a kind of optical diffusion, belong to optical material field.
Background technology
Existing optical diffusion is widely used in LCD backlight source, advertising lamp box, lighting, mobile communication equipment button etc. to be needed on the device of light source to provide Uniform Illumination.The fast development of LCD backlight source in recent years and the widespread use in mobile communication equipment display, laptop computer displays, desktop computer display and large-size liquid crystal television, improve increasingly to the performance requirement of optical diffusion in backlight.
Existing optical diffusion mostly is the organic film adopting stretching technique to produce and the multilayer film adopting coating method to produce, the diffusion particle wherein containing different-grain diameter in the coating layer of the multilayer film adopting coating method to produce.In the assembling process of backlight source module and liquid crystal indicator, above-mentioned diffusion barrier is by being directly positioned in light guide plate after cross cutting.In assembling and client's use procedure, be easy to produce owing to rubbing between the anti-adhesive linkage of diffusion barrier and light guide plate, cause anti-adhesive linkage internal divergence particle to come off, make optical transport and show bad, therefore, those skilled in the art is devoted to develop a kind of diffusion barrier product to solve the problem that comes off.
Prior art is provided with diffusion particle thus the isolation realized between anti-adhesive linkage and light guide plate by filling out at anti-adhesive linkage, and in assembling and client's use procedure, be easy to produce owing to rubbing between the anti-adhesive linkage of diffusion barrier and light guide plate, cause anti-adhesive linkage internal divergence particle to come off, make optical transport and show bad; Optical diffusion provided by the invention, by techniques such as embossing, the resin material on anti-adhesive linkage surface is rendered as roughness, concave surface makes anti-adhesive linkage can not produce large-area contact with light guide plate with protruding existence, just form point cantact with light guide plate, space is there is between contact, thus realize buffer action certain between anti-adhesive linkage and light guide plate, and be provided with light diffusion particle without the need to filling out again, and then the transmission that causes because diffusion particle comes off can not be there is and show bad problem; While guaranteed performance, structure and production technology simpler.
