Projected Capacitive Touch Screen Technology
5 point projected capacitive touch screen are especially for the size under 15" , like 12.1" , 10", 9" , 7" and many customized size.
Projected Capacitive Touch (PCT; also PCAP) technology is a variant of capacitive touch technology . All PCT touch screens are made up of a matrix of rows and columns of conductive material , layered on sheets of glass . This can be done either by etching a single conductive layer to form a grid pattern of electrodes , or by etching two separate , perpendicular layers of conductive material with parallel lines or tracks to form a grid . Voltage applied to this grid creates a uniform electrostatic field , which can be measured . When a conductive object , such as a finger , comes into contact with a PCT panel , it distorts the local electrostatic field at that point . This is measurable as a change in capacitance . These kind of the touch screen are well used in many applications.
