Abstract
The invention discloses a liquid crystal light valve. The liquid crystal light valve comprises a protection sheet, a light filter sheet, a liquid crystal display (LCD) and polarizer sheets, at least four sheet-shaped structures are arranged, and the liquid crystal light valve further comprises pressure sensitive adhesive layers which are used for gluing and arranged between each two adjacent sheet-shaped structures of the protection sheet, the light filter sheet, the liquid crystal display (LCD) and the polarizer sheets. The liquid crystal light valve has the advantages that the pressure sensitive adhesive layers are utilized to glue each sheet-shaped structure, thereby stress is uniformly applied to each sheet-shaped structure, Newton rings or rainbows are not prone to be generated, and the product quality of the liquid crystal light valve is improved.
Description
The present invention require on June 29th, 2011 submit that Patent Office of the People's Republic of China, application number are 201110179850.9 to, denomination of invention is the right of priority of the Chinese patent application of " a kind of diffusion value of liquid crystal light valve and liquid crystal light valve structure of dependence of angle of improving ", its full content is by reference in conjunction with in the present invention.
Technical field
The present invention relates to the electric welding technical field, particularly relate to a kind of liquid crystal light valve.
Background technology
Electro-welding arc mainly comprises infrared ray, luminous ray and ultraviolet ray, and arc light is very large to people's eye injury, even can cause losing one's sight.Liquid crystal light valve is for the twisted nematic liquid crystals product on the arc welding mask.The dual optical filtering of its energy, ultraviolet ray and the infrared ray harmful radiation of avoiding electric arc to produce, and the welding high light is stopped the generation of electric ophthalmia to the injury that eyes cause.
As shown in Figure 1, the structural representation for traditional a kind of liquid crystal light valve comprises: a plurality of schistose textures such as screening glass 001, polaroid 002, liquid crystal display LCD003 and optical filter 004 connect and compose successively.Wherein, the quantity of optical filter 002, liquid crystal display LCD003 and polaroid 004 can be adjusted according to actual condition.A plurality of schistose textures can fit tightly connection in the liquid crystal light valve in order to make, and as shown in Figure 2, it is bonding that existing liquid crystal light valve uses black shading rubber belt 100 to carry out around it.
Yet bonding method meeting around adopting be so that each schistose texture discontinuity in the liquid crystal light valve easily produces air layer in the middle of each schistose texture, and easily generation Newton ring or rainbow under the normal temperature, thereby make the quality of products of liquid crystal light valve.
Summary of the invention
For solving the problems of the technologies described above, the embodiment of the invention provides a kind of liquid crystal light valve, and with the purpose that realizes improving the quality of products, technical scheme is as follows:
A kind of liquid crystal light valve; comprise: screening glass, optical filter, liquid crystal display LCD and at least four schistose textures of polaroid; also comprise: be arranged between two adjacent in described screening glass, optical filter, liquid crystal display LCD and polaroid schistose textures, be used for carrying out bonding pressure-sensitive adhesive layer.
Preferably, the thickness of described pressure-sensitive adhesive layer is that 10um is to 30um.
Preferably, also comprise: use successively the bonding screening glass of pressure-sensitive adhesive layer, ground floor polaroid, ground floor liquid crystal display LCD, second layer polaroid and optical filter.
Preferably, also comprise: use successively the bonding screening glass of pressure-sensitive adhesive layer, ground floor polaroid, ground floor liquid crystal display LCD, second layer polaroid, second layer liquid crystal display LCD, the 3rd layer of polaroid and optical filter.
By using above technical scheme, a kind of liquid crystal light valve that the embodiment of the invention provides uses pressure sensitive adhesive that each schistose texture is carried out bonding, can be so that uniform stressed between each schistose texture, be difficult for producing Newton ring or rainbow, thereby the product quality of liquid crystal light valve is improved.
