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.

Everyday new companies open, and companies die.

Most died companies was caused by the founders,including his bad management,his short dream and his attitude to the customers.

Mianyang Prochema Commercial Co.,Ltd. is not an old company,but will be a 100-year company,because his founder has that dream.

Founder himself can not live 100 years,but his spirit and attitude will.

Honest and responsible and insistant are the key points for a company to be existed long enough.

In China,real 100-year company is rare.Hope Mianyang Prochema will the one.
