Different kinds

The touch panels:

The touch panel is a modern kind of computer input.
Resistant, fast reaction, thin and no space needed.

Our production unit is 20 000 square feet with 50% of clean room of 3 classes (10 000, 1 000 and 100)
Production capability: 40 000 pieces/month
Digital or analog with 4 or 8 output conductors.
On top film depending your needs function of the pressure, light transmission etc ...
Lower substrat can be plexi, PC, or glass depending the rigidity needed.

Our new 5 conductors panel

The 5 conductors touch panel is the best way for high resitance and stable in the time applications.
Same technology as the 4 conductors the structure is a lower panel * (glass or film) and an upper one * film.

In the 5 wires system, the detection line (the fifth silver wire) is connected to the upper panel; the 4 others are connected to the lower panel.

When the upper panel is taped or pressed, a contact is established with the lower panel, the fifth wire conduct the information to the controler.
The controler can manage this information.
Best thing: Even if the upper panel is damaged or scratched the touch panel can work.

* ITO = Indium Tin Oxide
