Abstract
A polaroid with double-face bond comprises a polarizing film, protection layers and bonding layers from the inside to the outside, wherein a protection layer is arranged on the upper surface of the polaroid and the lower surface of the polaroid. The bonding layer has double-face binding property, with one side applied with the protection layer and the other side applied with a terminal apparatus using the Polaroid, hence the polaroid equipped with double-face bond is formed. The double-face protection layer of the polaroid provided by the utility model can better protect the core polaroid, and double-face binding property enables the polaroid to be directly applied with the outer surface of an apparatus screen. Production technology of a display screen or a touch screen is simplified, and production cost is reduced.
Description
Technical field
The utility model relates to field of liquid crystal display, is specifically related to the bonding polaroid of a kind of double-sided belt.
Background technology
Polaroid is liquid crystal panel vital part; it is one of industry of current industry hot topic; being of wide application of polaroid; not only can use in LCDs as polarisation material; also optical filtering, auto bulb non-glare treated and the light quantity adjuster etc. that can be used for sunglasses, anti-glare eye protector, photographic goods, other still has polarizing microscope and special medical glasses.
The material of polaroid is the polymkeric substance of doping iodine molecule.While arranging in the same direction due to iodine molecule, there is asymmetric electronics (cloud) density, so the polarized light absorption coefficient of different directions is different.If when the polarised direction of light is vertical with iodine molecule chain long axis direction, polarized light can pass through completely.The absorption axes direction that polarised direction is called to polaroid.Only have with absorption axes direction linear polar biased light in the same way and could see through, otherwise see through light intensity, weaken, until cover completely thereupon.
Present widely used polaroid generally comprises one deck bonding coat.Such polaroid only has one side viscosity; being generally used for polaroid and glass, panel etc., to carry out one side bonding; but show that at touch-control integrated, display screen needs in the product application such as additional sealer or cover glass; need to use surface coating technology to increase again one deck jointing material at polaroid; by the display screen with polaroid and touch-screen or sealer laminating, then through techniques such as froth breakings, removing the bubble between laminating.But in process of production, increase the operation of adhesive material, once that technological process causes is bad, easily make to need two damage of product of laminating, cost is higher, and the production cycle is longer.
Summary of the invention
The purpose of this utility model is to provide a kind of protection that can strengthen polaroid, and has the polaroid of both-sided adhesive.
For achieving the above object, the technical solution adopted in the utility model is:
The polaroid that a kind of double-sided belt is bonding; comprise from inside to outside polaroid, protective seam, bonding coat; it is characterized in that: the upper and lower surface of described polaroid all respectively has layer protective layer; described bonding coat has biadhesive; one side and protective seam laminating; opposite side, by the terminal device laminating with using this polaroid, has formed the polaroid with both-sided adhesive.
Described bonding coat does not have releasable in a side that is fitted in protective seam.
The surface coverage of described bonding coat has release film, is the PE(tygon of one-sided coating EVA layer (ethylene-vinyl acetate copolymer)) film, this film has low viscosity,, can protect bonding coat surface not contaminated.
Described protective seam is optical homogeneity and the good TAC(cellulose triacetate of the transparency) film, be used for completely cutting off moisture and air, protection polaroid.
The two-sided protective seam of the utility model polaroid can better be protected its core polaroid, and both-sided adhesive can make this polaroid directly and the outside surface protective seam of device screen is bonding, has simplified the production technology of display screen or touch screen, has reduced production cost.The utility model polaroid also can be used for sunglasses, anti-glare eye protector, photographic goods simultaneously optical filtering, auto bulb non-glare treated, light quantity adjuster, polarizing microscope and special medical are with in eyewear products.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Illustrate: 1, release film 2, bonding coat 3, protective seam 4, polaroid.
Embodiment
?below by accompanying drawing, the utility model is further detailed.
The polaroid that a kind of double-sided belt is bonding; comprise from inside to outside polaroid 4, protective seam 3, bonding coat 2; wherein; the upper and lower surface of described polaroid 4 all respectively has layer protective layer 3; described bonding coat 2 has biadhesive; one side and protective seam 3 laminatings, opposite side, by the terminal device laminating with using this polaroid, has formed the polaroid with both-sided adhesive.
Polaroid 4 is by PVA(polyvinyl alcohol (PVA)) to make after the dyed stretching of film, this thing is the major part of polaroid, also claims polarisation former film.Polaroid 4 has determined polarizing properties, the transmitance of polaroid, is also the major part that affects polaroid color harmony optical durability simultaneously.
Protective seam 3 is easily to absorb water, fade and lose polarizing properties due to polaroid 4 that PVA film is made, therefore need to be on its both sides with one deck optical homogeneity and the good TAC(cellulose triacetate of the transparency) film completely cuts off moisture and air, protects polaroid 4.
Bonding coat 2(Adhesive) a side is to be bonded on protective seam 3, and its technological requirement has not allowed releasable, and its opposite side is used in end product laminating polaroid and that use.
Release film 1 is the PE(tygon of one-sided coating EVA layer (ethylene-vinyl acetate copolymer)) film, there is low viscosity, play protection bonding coat surface.
Claims (3)
1. the polaroid that double-sided belt is bonding; comprise from inside to outside polaroid, protective seam, bonding coat; it is characterized in that: the upper and lower surface of described polaroid all respectively has layer protective layer; described bonding coat has biadhesive; one side and protective seam laminating; opposite side, by the terminal device laminating with using this polaroid, has formed the polaroid with both-sided adhesive.
2. the bonding polaroid of a kind of double-sided belt according to claim 1, is characterized in that: the surface coverage of described bonding coat has release film.
3. the bonding polaroid of a kind of double-sided belt according to claim 1, is characterized in that: described protective seam is optical homogeneity and the good TAC film of the transparency.
