The opposite horizontal and vertical edges include light detection. These detections are utilized to record the beams that may have been interrupted while the panel was touched. Two crossing beams which are interrupted classify the horizontal and vertical coordinates of screen position chosen.
An electrical touch panel is assembled with two transparent plates separated through a short distance. One of the plates is coated along with a conducting material and another is resistive material. While the outer plate is touched, this is forced into relation with the inner plate. The contact makes a voltage drop which is converted to a match value of the chosen screen position.
