With standard sizes ranging from 3.8” to 26”, Touch International’s resistive touch screens are available as off-the-shelf touch panels or as fully customized touch solutions and are form, fit or function replacements for 3M™ and Elo™ touch sensors. Allowing for versatile input methods, Touch International’s resistive products work with bare and gloved fingers and any other input device.





The resistive touch screen 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.


Top 5 Resistive Highlights

  • Low power consumption
  • Liquids do not affect touch screen performance
  • Works with finger, gloves and any pointing device

Disadvantages

  • Requires periodic recalibration
  • Less durable than other touch technologies
  • Lower transmittance and overall optical quality
