Model: Projective Capacitive Touch Screen (PCAP)

The operation theory: utilizing the capacitance sensing, coming from the contacting of transparent electrodes on ITO, with fingers or inductive objects, then computing by controlling IC and transfer to coordinates data for operating system interpretation.

Due to the electric field scatters as projective mode, the inductive capacitance between fingers and electrodes is called Projective Capacitance.

PCAP can upgrade through various types of front cover lenses, like HC (hard coat), AR (anti-reflection), AG (anti-glare), AS (anti-smudge) or AF (anti-fingerprint), strengthen glass etc.
