Resistive Touch Technology
A resistive touch technology sensor consists of a piece of glass with a conductive coating on top, plus a polyester top sheet with a conductive coating on the bottom. The conductive surfaces are held apart by "spacer dots," which are typically glass beads that are silk-screened onto the coated glass. On a 5-wire design (the most commonly used type of resistive touch technology in large-screen Point-of-Sale applications), a voltage is applied to the four corners of the glass layer. When a person presses on the top sheet, it is deformed and its conductive side comes in contact with the conductive side of the glass, effectively closing a circuit. The voltage at the point of contact is read from a wire connected to the top sheet.
| Advantages | Disadvantages |
| Can be activated with any device | Less durability as compared to other technologies |
| Low cost solution | Less transmittance and overall optical quality |
| Low power consumption | Requires periodic recalibration |
Touch monitors using 5-Wire Resistive technology are typically best for the following environments:
- Point-of-sale terminals
- Industrial machine control
- Handheld computers
- Medical equipment
- Office automation
