Point, it suffers from and is widely applied in the every field of production and living, technology is also very mature, therefore, as production touch screen
Producer, production efficiency, cost, yield become its core competitive power factor for occupying market.LCD display is the weight of touch screen
Want component part, the display screen part in LCD display module generally by upper polaroid, upper glass plates, liquid crystal layer, lower glass plate,
Down polaroid successively forms.
Traditional polaroid can mainly be generated polyvinyl alcohol (PVA) film of polarization light by centre, then on two sides is compound
Transparent triacetate cellulose membrane (TAC) protective film composition also developed reflective polaroid, semi-transparent according to different use requirements
Emitting polaroid, transmission-type polaroid etc., reflective polaroid pass through the light of selective reflecting back light system, make it not by LCD
Down polaroid absorbed, so that the part light of LCD full view is re-used；Make as a result, axial brightness increase about 60% with
On, it is widely used in liquid crystal display.Reflective polaroid is by being arranged diffusion layer, the expansion on the surface layer of polaroid
The substrate surface for dissipating layer has the diffusion particle with concealing function, and diffusion particle is solidified by UV in substrate surface layer；Diffusion particle
Generally PMMA material, the light that goes out because of the difference of UV glue and diffusion particle material in diffusion particle and UV glue junction have folding simultaneously
Light and reflected light are penetrated, therefore the profile in diffusion particle Yu UV glue junction shows the vision taste of point influence display screen,
But the increase or application environment sampled with consumer to liquid crystal display put forward higher requirements liquid crystal display effect,
Existing reflective polaroid bring point problem is cannot be received.
Utility model content
The purpose of this utility model is to provide a kind of reflective polaroids, to solve prior art reflective polaroid
The diffusion particle of diffusion layer surface is reflected with substrate contact surface, point occurs so as to cause the surface in diffusion particle,
The technical issues of influencing the visual effect of display.
A kind of reflective polaroid provided by the utility model, which is characterized in that the reflective polaroid includes by upper
The first diffusion layer, the first TAC layer, multi-layer thin film layer, the second TAC layer, the second diffusion layer set gradually under, in which:
First diffusion layer include the first diffusion layer substrates and several first diffusion particles, it is described several first
Diffusion particle is hemispherical and is evenly distributed on the first diffusion layer substrates upper surface, several first diffusion particles and first
Diffusion layer substrates are that same material is integrally formed；
Second diffusion layer includes the second diffusion layer substrates and several second diffusion particles；It is described several second
Diffusion particle is hemispherical and is evenly distributed on the second diffusion layer substrates lower surface, several second diffusion particles and second
Diffusion layer substrates are that same material is integrally formed.
Further, there are also layer protecting films on first diffusion layer.
Further, the first psa layer is additionally provided on the protective film, the upper surface of the first psa layer has first
Release film.
Further, the second psa layer is also set up under second diffusion layer, the lower surface of the second psa layer has second
Release film.
Further, the side of first release film is provided with the first stripping portion, and the side of second release film is set
It is equipped with the second stripping portion.
Further, first stripping portion and the corresponding setting of the second stripping portion.
Further, first diffusion layer, the second diffusion layer material are ultraviolet cured adhesive.
Above-mentioned reflective polaroid, by by the substrate of diffusion layer and diffusion particle be designed to same material and integrally at
Type avoids and occurs contact facial contour between diffusion particle and substrate, thus fundamentally avoid light in diffusion particle and
Reflex on substrate contact surface eliminates " point ", to improve the display quality of display；And this kind of diffusion layer
Preparation process can be realized the integrated molding of matrix and diffusion particle, diffusion grain is coated on substrate without additional technique
Son effectively simplifies technique, improves production efficiency, reduces product cost.
