Projected Capacitive Touch panel:
Projected capacitive touch panels are built with two parallel layers of ITO but, 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.

Capacitive Touch Screen:
Capacitive touch screen is very different with traditional resistive touch screen. When the resistive touch screen works, you can only judge a touch point. And if there are two or more touch points, you can not make the right judgments. So the resistive touch screen applies only to judge a few simple actions such as click, drag and drop. The capacitive multi-touch screen can decompose the user's touch into colleting multi-point signal and determining the significance of the signals, and complete the judgments of complex action. Moreover, you can feel it when you lightly touch the projected capacitive touch sensor panel. Better durability, more than 90% light transmission rate, high transparency than the traditional resistive touch screen are the advantages of our products.
