Allowing for versatile input methods, Touch International’s resistive products work with bare and gloved fingers and any other input device. The resistive 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. On a 5-wire resistive design (the most commonly used kind of resistive screen in large format POS applications), a voltage is applied to the 4 corners of the glass layer. 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.
