21.5 inch 4 wire resistive touch screen panel with USB or RS232 interface

Products Description:

Shenzhen GreenTouch 4 Wire Resitive touchscreen consists of a glass layer with a conductive coating on top

and a polyester top sheet with a conductive coating on the bottom. The conductive surfaces are held apart by

"spacer dots", usually glass beads that are silk-screened onto the coated glass.

    When a person presses on the top sheet, its conductive side comes in contact with the conductive side of the

glass, effectively closing a circuit (this is called pressure sensing). The voltage at the point of contact is read from

a wire connected to the top sheet.It can be touched by finger, gloved finger, leather or stylus pen.It is inherently of

many advantages such as high accuracy, quick response, drift-free, stable and long durability for a life time of 1,000,000 times finger touches.
