Description

A kind of multilayer heat radiation type capacitance touch screen

Technical field

The utility model relates to touch-screen field, is specifically related to a kind of multilayer heat radiation type capacitance touch screen.

Background technology

Be at present all glass structure at every projection-type capacitive touch screen panel on the market, projection-type capacitive touch screen structure, is made up of top glass panel+optical cement+bottom sensor (sensor material can be ITO film or ito glass).

Each structure function:

1. top glass panel---the cover of touch-screen, the surface of contact that user taps

2. optical cement---the solid-state or liquid glue of the high transparency of gluing panel and sensor

3. the conducting wire plate of bottom sensor---PET or glass baseplate, is used for wiring topology

Basic functional principle:

When user's finger taps panel, will an electric capacity in parallel in sensor circuit, thus the total capacitance of sensor on this sweep trace is changed.Special control IC will calculate the coordinate position of touch point according to the capacitance variations before and after scanning, be presented on screen.

The drawback of glass panel structure projection-type capacitive touch screen:

The complex process that face glass and sensor are fitted, needs high-end devices and laminated material, affects production efficiency and production capacity, because the cost of face glass is high, and complex process, therefore the capacitance touch screen price be processed into is also quite high.

The advantage of glass panel structure projection-type capacitive touch screen:

Because glass panel structure, therefore it has good thermal insulation, and this makes the heat in circuit to distribute.
