Projected Capacitive Touch Screen
3G Technology's Projective Capacitive Touch Panel is made of all new materials and processes that make it more durable and reliable. The standard sizes from 3.8" to 26" are available.
3G Technology Inc. offers you the newest projective capacitive touch technology to meet your requirement. The Projected Capacitive Touch Panel (PCAP) is made of single or double layers of ITO (Indium Tin Oxide) which is ranked by interlaced X-axis and Y-axis.
The operation theory : utilizing the capacitance sensing, which comes 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) etc.
