COF TP Projected Capacitive Touch Screen 21.5 Inch With USB Touch Controller Board

21.5inch Projected Capacitive Touch Screen Panel with USB Touch Controller Board / ILITEK / EETI

Product Specification:

Projected Capacitive Touch panel:

Projected capacitive touch panels are built with two parallel layers of ITO , but unlike the old and cheap resistive touch panels, the ITO layers in a projected capacitive touch panel are sealed between two sheets of glass by an optically clear adhesive.

• There is no air gap between layers like in a resistive touch panel.
• The patterns on the two parallel ITO layers form a grid of capacitors.
• The electric fields of these capacitors are projected through the top layer of glass.
• When the user places a finger near the top surface of the touch panel, it couples with the electric fields.
• This coupling changes the capacitance of several of the capacitors in the vicinity of the finger.
• An algorithm converts these changes in capacitance into a location along the X and Y axes of the panel.
