Projected capacitive contact (PCT; also PCAP) technological know-how is often a variant of capacitive touch technological know-how. All PCT touch screens are made up of a matrix of rows and columns of conductive content, layered on sheets of glass. This can be carried out possibly by etching one conductive layer to variety a grid pattern of electrodes, or by etching two different, perpendicular levels of conductive substance with parallel strains or tracks to kind a grid. Voltage placed on this grid generates a uniform electrostatic field, which can be measured. When a conductive item, like a finger, arrives into connection with a PCT panel, it distorts the nearby electrostatic subject at that point. This really is measurable as a modify in capacitance.
