Projected Capacitive Touch Screen Technology
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 .

| Comparison between Capacitive Touch Panel and Resistive Touch Panel |
| Capacitive Touch Panel |
Resistive Touch Panel |
| Touch (no pressure needed) |
Press (pressure activated) |
| No calibration required |
Calibration required (resistance drift on film) |
| Better Durability, No significant aging |
Display turns white when aging |
| Handles high temperature |
Film breaks down at high temperature |
| Better Transparency, less optical power needed |
Low transmission |
| Can be vandal-proof (thick glass/plastic) |
Easily damaged (thin top layer) |
| Scratch Resistant (with glass) |
Prone to scratch without hard coat |
| Stylus not a must |
Need stylus, easy to lose |
