4-Wire Resistive Touchscreens
4-Wire Resistive touch technology is comprised of a glass or acrylic panel that is coated with electrically conductive and resistive layers. The thin layers are separated by invisible, dielectric dots. When operating, an electrical current moves through the screen. When pressure is applied to the screen the layers contact each other, 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. Resistive screens are very durable and can be used in a variety of environments. Clarity is not as good as some of the other technologies. This type of screen is recommended for individual, home, school, or office use, or less demanding point-of-sale systems, restaurant systems, etc.
