Summary of the invention
Based on this, be necessary to provide a kind of can the high-quality touch-screen of more thinning, and overcoming the situation that to rupture appear when climbing to frame ink in transparency conducting layer, improving its product yield.
A kind of high-quality touch-screen, comprise attach successively liquid crystal surface flaggy one, shielding ITO layer, liquid crystal surface flaggy two, light shield layer, transparent insulating layer, transparency conducting layer, touch line layer, polaroid, cover plate and anti-reflective layer.Wherein, described light shield layer covers liquid crystal surface flaggy surrounding, and form the frame outside touch screen window, described liquid crystal surface flaggy two and described light shield layer together cover by described transparent insulating layer; Described transparent insulating layer is transitioned into the surface of described liquid crystal surface flaggy two from the surface smoothing of described light shield layer, eliminates the height fall produced between described light shield layer and described liquid crystal surface flaggy.
Preferably, described cover plate is PET plate.
Preferably, described cover sheet thickness is less than 0.5mm.Relatively traditional touch screen structure, traditional touch function layer is prepared on glass cover-plate, and the touch function layer of this case is then be prepared on the glass plate of liquid crystal surface flaggy, then attaches polaroid, and cover plate is independent additional protective seam.In other words, cover plate does not participate in the preparation process shielding ITO layer, transparent insulating layer and touch line layer, and the cover plate of so this case, then without the need to possessing resistance to elevated temperatures, also just can select the material that can reach hardness requirement beyond glass.As PET plate and epoxy resin board etc. can reach hardness requirement when thickness is less than 0.5mm.So just can realize progress one thinning of high-quality touch-screen.
Preferably, the thickness of described transparent insulating layer is greater than 12nm.
Preferably, described anti-reflective layer is frosted material.
Preferably, described light shield layer is black out ink or shading Coating Materials.In order to meet market demand described in light shield layer be black out ink, by the mode of printing, black out ink is printed on the surrounding of described liquid crystal surface flaggy; Or described light shield layer is shading Coating Materials, by the mode of plated film, by the surrounding of shading Coating Materials sputter at described liquid crystal surface flaggy.
Preferably, described black out ink is electrically conductive ink or non-conductive ink.
Preferably, described shading Coating Materials is plated film non-conducting material or plated film conductive material.In order to meet the demand in market, described black out ink can adopt electrically conductive ink or non-conductive ink.And described shading Coating Materials can adopt plated film non-conducting material or plated film conductive material.Wherein, electrically conductive ink can select ink for screen printing, silver slurry or carbon slurry.The present invention is made to have a wide range of applications scene, to meet the user demand of different user.
Beneficial effect of the present invention is: the invention provides a kind of can the high-quality touch-screen of more thinning, and overcoming the situation that to rupture appear when climbing to frame ink in transparency conducting layer, improve product yield.
Accompanying drawing explanation
Fig. 1 is the hierarchical structure schematic diagram of the high-quality touch-screen of an embodiment of the present invention.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the embodiments of the present invention are explained in detail.But, persons of ordinary skill in the art may appreciate that in each embodiment of the present invention, proposing many ins and outs to make reader understand the application better.But, even without these ins and outs with based on the many variations of following embodiment and amendment, each claim of the application technical scheme required for protection also can be realized.
As shown in Figure 1, a kind of high-quality touch-screen, comprise attach successively liquid crystal surface flaggy 1, shielding ITO layer 2, liquid crystal surface flaggy 23, light shield layer 4, transparent insulating layer 5, transparency conducting layer 6, touch line layer 7, polaroid 8, cover plate 9 and anti-reflective layer 10.Wherein, described light shield layer covers liquid crystal surface flaggy surrounding, and form the frame outside touch screen window, described liquid crystal surface flaggy two and described light shield layer together cover by described transparent insulating layer; Described transparent insulating layer is transitioned into the surface of described liquid crystal surface flaggy two from the surface smoothing of described light shield layer, eliminates the height fall produced between described light shield layer and described liquid crystal surface flaggy.
As shown in the above, owing to first covering transparent insulating layer 5 with on the liquid crystal surface flaggy 23 of light shield layer 4 before covering transparency conducting layer 6, light shield layer 4 and liquid crystal surface flaggy 23 together cover by this transparent insulating layer 5, and when covering transparent insulation 5 layers, transparent insulating layer 5 is slowly smoothly transitioned on light shield layer 4, thus eliminate the height fall produced between light shield layer 4 and liquid crystal surface flaggy 23, avoid the vertical bank that transparency conducting layer 6 produces when light shield layer 4 is transitioned into liquid crystal surface flaggy 23.And light shield layer 4 can be hidden completely by transparent insulating layer 5, stop the burr phenomena at light shield layer 4 edge.So when transparency conducting layer 6 covers on transparent insulating layer 5, transparency conducting layer can be avoided completely to occur the situation of fracture and breakpoint, improve the yields of high-quality touch-screen, reduce production cost.In addition, because traditional touch function layer is prepared on glass cover-plate, the touch function layer of this case is then be prepared on the glass plate of liquid crystal surface flaggy 23, then attaches polaroid 8, and cover plate 9 is independent additional protective seam.In other words, cover plate 9 does not participate in the preparation process shielding ITO layer 2, transparent insulating layer 5 and touch line layer 7, so the cover plate 9 of this case is without the need to possessing resistance to elevated temperatures, also the material that can reach hardness requirement beyond glass can just be selected, as PET plate and epoxy resin board etc. can reach hardness requirement when thickness is less than 0.5mm.So just can realize progress one thinning of high-quality touch-screen.Wherein shielding ITO layer 2 is arranged on liquid crystal surface flaggy 1, plays reinforcement effect, prevent it from secretly splitting to liquid crystal surface flaggy.Touch line layer 7 and be arranged at polaroid 8 times, can effectively prevent polarisation problem, the setting of anti-reflective layer 10 prevents effectively under the irradiation of high light, and people cannot see the problem of high-quality touch-screen content clearly, and frosted material can increase light refraction effectively.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
