An APR touch screen is built up by a glass plate and 4 piezo electric transducers mounted to the backside of the glass plate. The transducers detect the accoustical wave created by the pressure to the glass plate.
The controller digitise the signal and compare it with the profile of each point of the glass plate that are stored in a memory.
