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.

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
