Projected Capacitive touch screen technology works off on an electrostatic field that is created by layers of conductive materials individually etched to form a grid pattern of electrodes. A touch event occurs when a finger or conductive stylus interferes with the electric field projected above the surface. This change in capacitance is detected by the controller which interprets the X and Y coordinates of the event. Multiple fingers can be tracked simultaneously and the controller supports common multi-touch gestures. Our projected capacitive touch panels feature a technology that allows them to be 'tuned' to operate through glass or polycarbonate facings of a variety of thicknesses.
