Touch Screen Details :
Introduction of 5Wire Resistive Touch Screen:

a ATouch's 5 Wire Resistive Touch Screen is of the most extensive application. It works by any kinds of physical touches, such as finger, gloved hand, rubber, etc. It is liquid resistance and contamination proof and even works in bad environment such as foul, dirt, greasiness, etc.
ATouch 5 Wire Resistive Touch Screen supports RS-232 & USB interfaces for:
a LCD flat display: 8.9"a 22"

5 Wire Resistive Touch Screen Benefits:
a Long lifetime (almost ten times of 4 Wire Resistive Touch Screen)
a Finger, gloved hand and stylus activation
a Contaminant proof and liquid resistance
a High accuracy and durability
a High resolution and sensitivity

5 Wire Resistive Touch Screen Working Principle:
The 5 Wire Resistive Touch Screen is a two layer structure,
1.ITO glass substrate with one side uniform resistive ITO coating.
2. A very thick polyester ITO film is tightly suspended over the top of ITO glass substrate. This ITO film has a hard, durable coating on the outer side, on an inner side with ITO coating.
3.The ITO glass and the ITO film is separated by printed small, transparent insulation spacer dots.

When the screen is touched, it pushes the ITO film to have an electrical contact with ITO glass (both on the ITO coating side). It then produces a voltage which is the analog representation of the position touched.

a The 5 wire touch screen controller is always ready for a touch, and the resistive layer
