About MAXVIEW TECHNOLOGY
4-Wire Resistive
Touchscreens
4-Wire Resistive touch technology consists of a glass or acrylic panel that is
coated with electrically condictive and resistive layers. The thin layers are
separated by invisible separator dots. When operating, an electrical current
moves through the screen. When pressure is applied to the screen the layers are
pressed together, causing a change in the electrical current and a touch event
to be registered.
4-Wire Resistive type touch screens are generally the
most affordable. Although clarity is less than with other touch screen types,
resistive screens are very durable and can be used in a variety of environments.
This type of screen is recommended for individual, home, school, or office use,
or less demanding point-of-sale systems, restaurant systems, etc.
