4 wire Resistive Touch Screen Description |
4-Wire Resistive Touch Screens are generally built with two layers of electrically conductive
materials (film+glass) separated by insulated dots.
When an object touches the device, the two layers come into
contact. The contact produces a change in electrical current and is
registered
as an analog touch event signal. The signal is then sent through the circuit to be converted into a
digital signal by the controller for the device
to compute the exact location of the touch event.
4-Wire Resistive Touch technology is suitable for applications that require ease of integration, low
power consumption, lightweight, portability,
cost effectiveness and compact mechanism.
Affordable, durable and versatile, the 4-wire resistive touch
screens are primarily used in mobile applications, such as smart
phones, PDAs, e-books,
web pads, digital cameras, GPS, and other consumer or office
electronics.
