    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 . These kind of the touch screen are well used in many applications.

    Comparison between Capacitive Touch Panel and Resistive Touch Panel

     

     

     

     

    Capacitive Touch Panel

    Touch (no pressure needed)

    No calibration required

    Better Durability, No significant aging

    Handles high temperature

    Better Transparency, less optical power 

    needed

    Can be vandal-proof (thick glass/plastic)

    Scratch Resistant (with glass)

    Stylus not a must

     

     

     

    Resistive Touch Panel

    Press (pressure activated)

    Calibration required (resistance drift on film)

    Display turns white when aging

    Film breaks down at high temperature

    Low transmission

    Need stylus, easy to lose

    Prone to scratch without hard coat

    Easily damaged (thin top layer)
