Principle
P e o p l e Ba s e d T r u l y C o n f i d e n t i a l
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
LCD
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
