Description
Technical field
The utility model relates to touch screen technology field more particularly to a kind of tablet computer capacitive touch screens.
Background technique
Touch screen is a kind of induction type liquid crystal display device of the input signals such as receivable contact, when contacting on screen
When graphic button, the haptic feedback system on screen can drive various connection devices according to the formula of preprogramming, can be used to take
For mechanical push button panel, and lively visual and sound effects are produced by liquid crystal display picture.
The working principle of capacitive touch screen is: when user's finger touch screen, will be connected in parallel with a capacitor touching
It touches in the SESNOR circuit of screen, so that total capacitance of the SESNOR in this scan line be made to change, control chip will
The coordinate position that touch point is calculated according to the capacitance variations of scanning front and back, is displayed on the screen.
Capacitive touch screen in the prior art on chip all integrated mainboards on usual touch screen, limits in this way
The use space of mainboard, meanwhile, the touch screen is thicker, limits the design space of entire tablet computer.
Therefore, the existing technology needs to be improved and developed.
Utility model content
In view of above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a kind of tablet computer capacitance touch
Screen, it is intended to solve the problems, such as that touch screen in the prior art is thicker to limit the design space of entire tablet computer.
The technical solution of the utility model is as follows:
A kind of tablet computer capacitive touch screen comprising:
ITOGLASS plate, the outer surface of the ITOGLASS plate are provided with a PET protection film, and the PET protection film passes through
OCA optical cement is pasted on ITOGLASS plate；
The inner surface periphery of the ITOGLASS plate has a foam by sticking double faced adhesive tape；
A connector is provided on the ITOGLASS plate.
Preferably, the connector is FPC plate.
Preferably, one is provided in the PET protection film tear hand.
Preferably, middle part is provided with a transparent apertures below the PET protection film.
Compared with prior art, tablet computer capacitive touch screen provided by the utility model, comprising: ITOGLASS
Plate, the outer surface of the ITOGLASS plate are provided with a PET protection film, and the PET protection film is pasted by OCA optical cement
On ITOGLASS plate；The inner surface periphery of the ITOGLASS plate has a foam by sticking double faced adhesive tape；The ITOGLASS plate
On be provided with a connector so that the capacitive touch screen is thinner, extend the design space of entire tablet computer.
