Abstract

The utility model discloses an anti-interference capacitive touch screen. A main body part of the anti-interference capacitive touch screen is formed by laminating a surface layer toughened glass, a first adhesion layer, a main circuit board, a second adhesion layer and a bottom layer polyester (PET)-indium tin oxide (ITO) film sequentially. A main interface of a flexible printed circuit (FPC) is in butt joint with the main circuit board, and an additionally-arranged independent grounding pin of the FPC is installed between the main circuit board and the PET-ITO film in pressing mode. The anti-interference capacitive touch screen is high in anti-interference capability.

Description

A kind of anti-interference type capacitive touch screen
Technical field
The utility model relates to a kind of anti-interference type capacitive touch screen.
Background technology
Existing capacitive touch screen module; Though price is low, it is controlled that its major defect is that exactly noise is difficult to, the size of noise; Will cause following some problem: 1) when capacitive touch screen carries out machine debugging, the noise that is difficult to the capacitive touch screen module is contained; 2) after the user uses a period of time, may make capacitive touch screen to work normally because of the difference of capacitive touch screen module noise, and after need proofreading and correct again, could will newly produce noise contain to fall; 3) its versatility is poor, must have the IC processor that matches just can satisfy the demands.Therefore, be necessary existing capacitive touch screen is carried out the improvement of interference free performance.
The utility model content
The utility model wants the technical solution problem to provide a kind of anti-interference type capacitive touch screen, and this anti-interference type capacitive touch screen antijamming capability is strong.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of anti-interference type capacitive touch screen; The main part of anti-interference type capacitive touch screen stacks gradually pressing by the PET ITO film of top layer tempered glass, first adhesion layer, main circuit board, second adhesion layer and bottom and forms; The main interface of FPC docks with main circuit board, and the independent grounding pin that FPC establishes in addition is fitted between main circuit board and the PET ITO film.
Silk-screen has a circle silver slurry line on PET ITO film.
PET refers to polyethylene terephthalate, and ITO refers to tin indium oxide.
Beneficial effect:
The anti-interference type capacitive touch screen of the utility model; Structural design is simple; Only need reserve PIN pin interface (being the independent grounding pin) at lead end; Stick on one deck PET ITO film at the main circuit board back side, the independent grounding pin of reserving is connected with the PET ITO film of lower surface, can realize good anti-interference effect; The utility model applicability is strong, can be used as universal capacitance plate, can reduce the die cost of die sinking.
Description of drawings
Fig. 1 is the general structure synoptic diagram of anti-interference type capacitive touch screen;
Fig. 2 is the structural representation of FPC;
Fig. 3 is for being printed with the synoptic diagram of a circle silver slurry line on the PET ITO film.
Label declaration: 1-top layer tempered glass, 2-first adhesion layer, 3-main circuit board, 4-PET ITO film, the chip that 5-FPC is last, 6-FPC, 7-independent grounding pin, 8-silver slurry line, 9-second adhesion layer.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Embodiment 1:
Shown in Fig. 1-3; A kind of anti-interference type capacitive touch screen; The main part of anti-interference type capacitive touch screen stacks gradually pressing by the PET ITO film of top layer tempered glass, first adhesion layer, main circuit board, second adhesion layer and bottom and forms; The main interface of FPC docks with main circuit board, and the independent grounding pin that FPC establishes in addition is fitted between main circuit board and the PET ITO film.
