Abstract
Touchscreen electronics for detecting debris on a display screen of a touchscreen system and alerting a user to the presence of the debris 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. The receivers may detect the beams from the transmitters, and each receiver may generate a receive signal. The controller communicates with the transmitters and the receivers and may be configured to analyze the receive signals to determine if debris may be present on the display screen. If so, then the controller may generate an alert signal to indicate that the display screen needs to be cleaned or examined.
