Overview:
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.
Features:
- 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.
