Abstract
Touchscreen electronics for detecting touches on a display screen broadly comprises a plurality of transmitters, a plurality of receivers, and a controller. Each transmitter may transmit at least one beam across the display screen, wherein the beam may be switched on and off in a repeated pattern. The receivers may detect the beams from the transmitters, and each receiver may generate an 'on' value that corresponds to the beam being switched on and an 'off' value that corresponds to the beam being switched off. The controller communicates with the transmitters and the receivers and may be configured to determine that a touch has occurred when the “on” value generated by one of the receivers transitions in a sequence from greater than an upper level to less than a lower level.
