Projected Capacitive Touch panel:
Projected capacitive touch panels are built with two parallel
layers of ITO but, but unlike the old and cheap resistive touch
panels, the ITO layers in a projected capacitive touch panel are
sealed between two sheets of glass by an optically clear adhesive.
There is no air gap between layers like in a resistive touch panel.
The patterns on the two parallel ITO layers form a grid of
The electric fields of these capacitors are projected through the
top layer of glass.
When the user places a finger near the top surface of the touch
panel, it couples with the electric fields.
This coupling changes the capacitance of several of the capacitors
in the vicinity of the finger.
An algorithm converts these changes in capacitance into a location
along the X and Y axes of the panel.
