Thread: Touchscreen overlays

Normally, in the touchscreens the film is glued on top of a thin piece of unbreakable glass.
The film alone, as far as i know, is hard to find. Is normally an OEM product, that requires minimum order quantities of hundreds pieces.
So i suggest you to find a cheap commercial touch screen (e-bay??), and try to detach the film, with the help of acetone. I say cheap, because all this procedure is VERY risky.
Then if you manage to attach this film on top of the factory attached, it will work. Dont forget, that if you will want the bottom film to respond to the touch, you must press harder,.

Or, equally risky, you could open up your expensive screen and try to hack the touchscreen interface.

If it's four wire analog, you may have a chance!

What if the exisiting touchscreen is of the type that uses field scanning, would that leak through the resistive touchscreen layer meaning that I wont have to press hard? I thiunk their called cleartouch or something like that.
