Principle


l Cp: parasitic capacitance

l Cf: finger capacitance

l When finger close to the touch panel the capacitance change: Cs = Cp + Cf

l Detect the finger by measuring the change of capacitance

l Arm glass or plastic covering the CTP make it high

reliability.

l Just approach without large force that make CTP work,

which bring you totally new touch feeling.

Capacitive TPResistive TP Touch panel

Assemble of resistive TP

Resistive Touch panelRequires pressure (stylus) for contact

between two resistive/conductive layers Prone to wear & tear

2 ITO layers required (plus spacer layer) Lower transparency than capacitive

High pointer precision

Capacitive Touch PanelRequires conductive object (finger)1 or 2 ITO layers

Excellent transparency possible (>90%)Low pointer precision
