Abstract
The utility model discloses a polaroid for a high-reflecting white ground semipermeable liquid crystal display, which comprises a stripping film layer, a polarizing film layer, a silver semipermeable film layer and a protection film layer which are overlapped from the top down. The stripping film layer is compounded at the upper surface of the polarizing film layer, the polarizing film layer is compounded at the upper surface of the silver semipermeable film layer, and the protection film layer is compounded at the lower surface of the silver semipermeable film layer. Only by compounding the polarizing film layer with the silver semipermeable film layer, the polaroid for the high-reflecting white ground semipermeable liquid crystal display can realize functions.
Description
Technical field
The utility model relates to a kind of polaroid, relates in particular to a kind of high reflection white background semi-transmission type LCD polaroid.
Background technology
Common semi-transmission type LCD polaroid is a kind of optical thin film with polarized light function that is composited with the layer high molecule material, is mainly used in field of display such as accutron.Mainly there is following shortcoming in common semi-transmission type LCD with its function of polaroid: reflectivity was not high when common semi-transmission type LCD was used with polaroid, though reflectivity was high when common silver-colored semi-permeable liquid crystal display used with polaroid, but background color is yellow partially again, the inconvenience when client uses.
The utility model content
The technical problems to be solved in the utility model is: reflectivity is not high when overcoming existing common semi-transmission type LCD and using with polaroid, though reflectivity is high when common silver-colored semi-permeable liquid crystal display uses with polaroid, background color is the problem of Huang partially again.
In order to solve the problems of the technologies described above, the utility model proposes following technical scheme: a kind of high reflection white background semi-transmission type LCD polaroid, this sheet has high reflectance, background color is white.What it comprised from the top down stack peels off rete, polarisation rete, silver-colored semi-transparent rete, protective film, peels off rete and is compounded in polarisation rete upper surface, and the polarisation rete is compounded in the semi-transparent rete upper surface of this silver, and protective film is compounded in silver-colored semi-transparent rete lower surface.
Preferably, this peels off rete is compounded in the polarisation rete by a pressure-sensitive adhesive layer upper surface.
Preferably, this polarisation rete is compounded in the upper surface of silver-colored semi-transparent rete by an adhesive phase.
Preferably, the tone range of this polarisation rete is: a*:1.0 ± 2NBS, b*:-6.5 ± 2NBS, L*:73 ± 2NBS.
The utlity model has following beneficial effect: the utility model uses new material silver semi-permeable diaphragm to be combined into product, this sheet has high reflectance, can reach the white background color again than high permeability and by the change tone, and not only background color was white but also very high reflectivity arranged when showing can to realize display device.

Fig. 1 is the schematic cross-section of the high reflection of the utility model white background semi-transmission type LCD with polaroid.
Fig. 2 is the decomposing schematic representation of the high reflection of the utility model white background semi-transmission type LCD with polaroid.
Embodiment
As shown in Figure 1, a kind of high reflection white background semi-transmission type LCD polaroid, what it comprised from the top down stack peels off rete 1, pressure-sensitive adhesive layer 2, polarisation rete 3, adhesive phase 4, silver-colored semi-transparent rete 5, protective film 6.Above-mentioned each layer is combined with each other by compounding machine.
This is peeled off rete 1 and is compounded in the upper surface of polarisation rete 3 by pressure-sensitive adhesive layer 2, and this polarisation rete 3 is compounded in the upper surface of silver-colored semi-transparent rete 5 by adhesive phase 4, and protective film 6 is compounded in the lower surface of silver-colored semi-transparent rete 5.
The thickness of pressure-sensitive adhesive layer 2, adhesive phase 4 can suitably be set according to the purposes of expecting, bond strength etc.Specifically, preferred thickness be 1 μ m to 100 μ m, more preferably 5 μ m are to 50 μ m, most preferably 10 μ m are to 30 μ m.
The tone range of this polarisation rete 3 is a*:1.0 ± 2NBS, b*:-6.5 ± 2NBS, L*:73 ± 2NBS.
Any suitable contact adhesive can be as the contact adhesive that forms pressure-sensitive adhesive layer 2, adhesive phase 4.Its object lesson comprises solvent-borne type contact adhesive, nonaqueous emulsion type contact adhesive, aqueous pressure sensitive adhesive and hot melt pressure sensitive adhesive.The preferred use contained the solvent-borne type contact adhesive of acrylate copolymer as base polymer, because it can show for the suitable pressure-sensitive adhesion performance (wettability, cohesiveness and cohesive) of light polarizing film and phasic difference film and excellent optical clarity, against weather and thermotolerance is provided.
This polarisation rete 3 comprises three layers, and promptly the middle layer is that polyvinyl alcohol (PVA) (PVA) film, both sides respectively are Triafol T (TAC) film.
These polarisation rete 3 production runes are as follows: the aqueous solution that 1, polyvinyl alcohol (PVA) (PVA) film is immersed iodine is to dye and this film to be stretched to 3 to 7 times of original length.Aqueous solution can contain boric acid, zinc sulfate, zinc chloride etc. as required, and perhaps the polyvinyl alcohol film can immerse in the aqueous solution of potassium iodide etc.And, the polyvinyl alcohol film can be soaked in water and cleans as required.2, water cleans the polyvinyl alcohol film and not only can remove the dirt or the flush away detackifier on striping surface, can also expand to prevent the non-uniform phenomenon of uneven dyeing for example etc. by making the polyvinyl alcohol film.Can be after the process that film is dyeed with iodine, among or before this film is stretched.Stretching can be carried out in the aqueous solution of boric acid or potassium iodide or in the water-bath.3, stretch polyvinyl alcohol (PVA) (PVA) film finish the back is very thin, is protection polyvinyl alcohol (PVA) (PVA) film, thus in polyvinyl alcohol (PVA) (PVA) film both sides each compound one deck Triafol T (TAC) film formation trilamellar membrane structure, polarisation rete 3.
The semi-transparent rete 5 of this silver is a kind of bloomings that have through function and reflection function.
The effect of this protective film 6 is: when reality is used this polaroid, and for preventing the polaroid various pollutions in surface, usually will be at polaroid surface recombination last layer diaphragm.Can be used as protective film 6 as any suitable diaphragm of polaroid.Usually use tygon (PE) film, polyester (PET) film as this film kind.
It is as follows with the method for polaroid to produce the high reflection of the utility model white background semi-transmission type LCD: the high reflection of the utility model white background semi-transmission type LCD can be carried out compound production by above-mentioned pressure-sensitive adhesive layer 2,4 pairs of above-mentioned each layers of adhesive phase with polaroid.Can adopt any suitable complex method.Concrete complex method is: the first step, carry out polarisation rete 3 and silver-colored semi-transparent rete 5 compound earlier; In second step, carry out polarisation rete 3 faces of peeling off compound product of the rete 1 and second step compound; The 3rd step, protective film 6 and second go on foot 5 of the silver-colored semi-transparent retes of the product after compound compound this polaroid finished product.
The utlity model has following beneficial effect: the utility model uses new material silver pellicle to be combined into product, this sheet has high reflectance, can reach the white background color again than high permeability and by the change tone, and not only background color was white but also very high reflectivity arranged when showing can to realize display device.
