  • 19.0" 4-Wire Resistive Touch Screen

Touch Innovations Touch Screens are perfect for PDAs, web phones, and other handheld consumer applications. The superior film on glass construction offers the very best light transmission reliability and durability.


Offering excellent durability and resolution, resistive technology is used in a variety of applications and environments. Resistive touchscreens consist of a glass panel with a coating of uniform resistivity, plus a polyester cover sheet which is tightly suspended from the top of the glass and separated from it by small, transparent insulating dots. The cover sheet has a hard, durable coating on the outer side, and a conductive coating on the inner side. When touched, the conductive coating makes electrical contact with the coating on the glass, and a touch is registered by the analog controller.

Benefits of Touchscreen technology:

  • Touchscreens enable first-time users to interface with computers instantly, without any operator training whatsoever
  • Touchscreens virtually eliminate operator errors because users make selections from clearly defined menus
  • Touchscreens eliminate keyboards and mice, which many novice users find intimidating and cumbersome to use
  • Touchscreens are rugged enough to stand up to harsh environments where keyboards and mice can become damaged
  • Touchscreens provide fast access to all types of digital content
  • Touchscreens ensure that no space is wasted because the input device is completely integrated into the monitor.


  • Proven Resistive Technology
  • Simplicity of Interface Electronics
  • Durable Plastic Construction
  • Less Susceptible to Accidental Touch
  • Ability to use Finger or Stylus to Activate Touchscreen
  • High Linear Analog Output

Resistive touchscreens deliver cost-effective, consistent and durable performance in environments where equipment must stand up to contaminants and liquids, such as in restaurants, factories, and hospitals. Disadvantages of resistive touchscreens include only 75% optical transparency and the fact that a sharp object can damage the resistive layers.
