Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Embodiment：
Fig. 1 and Fig. 2 are referred to, the present invention provides a kind of technical scheme：A kind of film shows touch interactive device, including
Flexible touch-control film 2 is laid in electrolyte front panel 1 and flexible touch-control film 2, the upper surface of the electrolyte front panel 1,
The lower surface of electrolyte front panel 1 is provided with driving electrodes 3 and receiving electrode 5, and driving electrodes 3 are arranged on receiving electrode 5
Left end, the lower end of the driving electrodes 3 is connected by connecting line with driving buffer 4, the data terminal of the driving buffer 4
It is connected with camera 6, the output end of the camera 6 is connected by data collecting card 7 with controller 8, the camera 6
Using the probe camera of OV7670 series, the controller 8 uses the process chip of ARM11 series, the receiving electrode 5
Signal end is connected with the control end of controller 8, and the flexible touch-control film 2 is included outside PET film 13, the PET film 13
Surface is equipped with inductive layer 12, all glued matcoveredn 11 in outer surface of the inductive layer 12, the appearance of the protective layer 11
Face fixation is glued on the inwall of flexible touch-control film 2.
Preferably, the protective layer 11 is provided with two layers, and two surfaces up and down of inductive layer 12 are glued at respectively；It is described
Protective layer 11 uses PP materials, and the thickness of PP materials is arranged between 100um-200um；The signal end of controller 8 passes through
RS232 interfaces 9 are connected with computer 10.
The protective layer 11 adopts PP materials popular on the market, and thickness is typically in 100um-200um or so, mainly
It is that silver paste is protected, smooth with wear-resisting, the features such as easily adsorbing, because than relatively thin and normal with higher dielectric
