Description
Technical field
The utility model relates to a kind of touch-screen, particularly relates to a kind of touch screen for smart electronics.
Background technology
Along with client requires more and more higher to the display of smart electronics product and touch, after numerous manufacturer adopts the full coating technique of touch screen being used for smart electronics, the benefit that product is thinning brought, not only improve the design of product, also simplify the production procedure of supply chain, reduce costs, no longer need to purchase touch-screen and liquid crystal panel respectively to different vendor.
At present, the cost of control of entirely fitting out display module costliness and yields is low makes a lot of manufacturer realize volume production, causes the manufacturer of the full coating technique of current practical application very few.Now main applying method is that OCA optical cement is directly fitted on the upper polaroid of display screen finished product, again touch-screen is located on the OCA optical cement of upper polaroid, touch-screen and display screen finished product are bonded together, the existing polaroid of this job operation is inconvenient to install, and need through 3 laminatings, and OCA optical cement cost compare is high, the release film on its two sides is consumptive material but occupies very large cost, if both sides release film mismatch, causes product bad, adds production cost.Simultaneously this job operation can cause optical cement to overflow in the backlight of display screen finished product, makes backlight cannot normal printing opacity, causes product bad, adds production cost.
Summary of the invention
The utility model provides a kind of touch screen for smart electronics, and this touch screen for smart electronics reduces the interference that display screen noise causes touch signal, and need not consider dust protection and anti-steam.
For achieving the above object, the technical solution adopted in the utility model is: a kind of touch screen for smart electronics, comprise touch module, display module and upper polaroid, the described upper and lower surface of upper polaroid is respectively by an OCA optical cement, the 2nd OCA optical cement and touch module and show module and bond; Once bonded by the 3rd OCA optical cement between polaroid and display module lower surface;
Described touch module comprises glass cover-plate, has the first plastic film layers and second plastic film layers of ITO sensing electrode layer, bonded by the 4th OCA optical cement between described glass cover-plate and the first plastic film layers, by the 5th OCA optical cement bonding between described first plastic film layers and the second plastic film layers;
Described display module comprises transparency carrier, lower transparency carrier, is disposed with liquid crystal layer, TFT thin layer between described upper transparency carrier, lower transparency carrier.
The technical scheme improved further in technique scheme is as follows:
1., in such scheme, described first plastic film layers is PET film, polypropylene film, polyethylene film or polyvinyl chloride film.
2., in such scheme, described second plastic film layers is PET film, polypropylene film, polyethylene film or polyvinyl chloride film.
3., in such scheme, the thickness of a described OCA optical cement, the 2nd OCA optical cement and the 3rd OCA optical cement is 0.05 ~ 0.25mm.
Because technique scheme is used, the utility model compared with prior art has following advantages:
The utility model is used for the touch screen of smart electronics, together with it achieves and polaroid and display screen, touch-screen to be pasted completely in seamless mode, full coating technique is except providing better display effect, touch-screen also makes intensity promote to some extent because combining closely with display screen, reduce the interference that display screen noise causes touch signal, and dust protection and anti-steam need not be considered; Secondly, because polaroid is bonded by OCA optical cement and the half-finished upper polaroid of display screen without backlight by the present invention, after touch-screen and upper polaroid bond, again the lower polaroid of backlight and display screen is fitted together, therefore avoiding optical cement overflows in backlight, ensure that the normal printing opacity of backlight energy, product can not be caused bad, reduce production cost.
