Utility model content
The purpose of this utility model be to provide for the deficiencies in the prior art a kind of production cost low, do not allow flimsy embedded capacitance touch screen while being applied to electronic product.
To achieve these goals, the utility model provides a kind of embedded capacitance touch screen, comprise cover plate, functional sheet, described functional sheet sticks on the bottom surface of described cover plate by OCA optics glue-line, the top end face surrounding of described cover plate is provided with for embedding the rim area in electronic product casing, and the bottom end face surrounding of described functional sheet is coated with the adhesive-layer of the display screen for being pasted on electronic product; Described cover plate is PET(English: Polyethylene terephthalate, poly terephthalic acid class plastics) cover plate.
Wherein, described functional sheet is provided with the flexible PCB of the control circuit board for being electrically connected electronic product.
Wherein, the back side of described flexible circuit front edge of board is fitted with steel disc.
Wherein, the front end of described flexible PCB is provided with conductive contact blade.
Wherein, the thickness of described PET cover plate is 0.1～0.25 millimeter.
Wherein, the thickness of described PET cover plate is 0.188 millimeter.
Wherein, the thickness of described OCA optics glue-line is 0.1 millimeter.
Wherein, described adhesive-layer is double sticky tape.
The utility model beneficial effect is: the utility model is installed on after electronic product, and cover plate is to embed in the shell of electronic product, does not have the problems such as light leak, thus do not need ink for screen printing, thus reduce production costs; And, because cover plate is subject to the protection of electronic product casing, so be not easy to damage; Further, the utility model adopts PET cover plate, and without strengthening, and PET material is cheap, thereby further reduces production costs.

Embodiment
In order to describe the technical solution of the utility model in detail, below in conjunction with the accompanying drawing of the utility model embodiment, the technical scheme of the utility model embodiment is carried out to clear, complete description.Obviously, described embodiment is a part of embodiment of the present utility model, rather than whole embodiment.Based on described embodiment of the present utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite without creative work, belongs to the scope that the utility model is protected.
Please refer to Fig. 2～5, embedded capacitance touch screen of the present utility model, comprises cover plate 1, functional sheet 2.Functional sheet 2 sticks on the bottom surface of cover plate 1 by OCA optics glue-line 3.The top end face surrounding of cover plate 1 is provided with for embedding the rim area 11 in electronic product casing 5, as shown in Figure 5, when the utility model is installed on after electronic product, shell 5 edges of electronic product just back-off prop up the rim area 11 of cover plate 1, form embedded structure.
The bottom end face surrounding of functional sheet 2 is coated with the adhesive-layer 4 of the display screen 6 for being pasted on electronic product, and in the time that the utility model is installed on electronic product, the bottom of functional sheet 2 can be pasted on by adhesive-layer 4 display screen 6 of electronic product.Wherein, cover plate 1 is PET cover plate, and cover plate 1 is made up of PET material, and PET is than the low price of glass, so the utility model can reduce production costs; Because PET itself has certain hardness, thus PET cover plate of the present utility model without strengthening operation, thereby can enhance productivity, make product the friendship phase shorten; Because PET itself has certain toughness, thus even if fallen and touch, also only can split, and can as glass, not splash everywhere, thus improve the security of product.
