Elo Touch Solutions

AccuTouch® Five Wire Resistive Touch Solutions

The Elo Touch Solutions AccuTouch touchscreens are based on proven five-wire resistive technology, the preferred solution for applications that demand reliability, input flexibility, and contamination resistance. AccuTouch touchscreens are available in bezel and zero-bezel designs, with proprietary Elo technology to deliver a touch response that is drift-free and accurate in high-use applications.

Elo AccuTouch delivers both X and Y measurements made on a stable rear glass layer where many other resistive touchscreen designs use a flexing plastic coversheet to measure only one axis. As a result, AccuTouch resistive touchscreens provide a longer product life, designed to withstand more than 35 million touches.

AccuTouch touchscreens can be sealed against contamination to support NEMA 4/4x/12 and IP65 standards. The zero-bezel design eliminates the need for a traditional front-bezel, achieving a smooth, seamless flat surface for a clean, modern look.

AccuTouch zero-bezel touchscreens use a flexible printed circuit cable that virtually eliminates the cable attachment bump that is typical on most resistive touchscreens and enables a smooth, flat integration. The screens work with standard Elo controller/chip solutions and drivers under a wide variety of operating systems, and are available in a set of standard products as well as customized designs.

Benefits

  • Zero-bezel configuration for seamless design to eliminate the traditional bezel that can collect dust and dirt.
  • 4H pencil hardness resists scratching.
  • Flat cable attachments for seamless integration and customization capabilities.
  • No lamination of additional décor foil is required which helps to reduce costs and supply chain complexity.
  • Stable, drift-free operation.
  • Broad input flexibility.
  • Contamination resistance.
  • Accuracy in high-use applications.
  • Can be sealed to support NEMA 4/4x/12 and IP65 standards upon integration.

Applications

  • Point-of-sale (POS) terminals
  • Voting machines
  • Industrial automation
  • Medical equipment
  • Office automation
  • Retail automation
  • Pharmacy automation



AccuTouch Five-Wire Resistive Touchscreens

Touch Products

The AccuTouch five-wire resistive touchscreens use a glass panel with a uniform resistive coating. A thick polyester coversheet is tightly suspended over the top of the glass, separated by small, transparent insulating dots. The coversheet has a hard, durable coating on the outer side and a conductive coating on the inner side.

AccuTouch Specifications

When the screen is touched, the conductive coating makes electrical contact with the coating on the glass. The voltages produced are the analog representation of the position touched. The controller digitizes these voltages and transmits them to the computer for processing.

AccuTouch five-wire technology utilizes the bottom substrate for both X and Y-axis measurements. The flexible coversheet acts only as a voltage-measuring probe. This means the touchscreen will continue working properly even with non-uniformity in the coversheet's conductive coating. The result is an accurate, durable and reliable touchscreen that offers drift free operation. AccuTouch screens are sealed against contamination and moisture. This prevents wicking of fluid between the coversheet and glass.

Elo offers enhanced, improved and AccuTouch True-flat configurations. Enhanced AccuTouch and improved AccuTouch touch screens have a flat flexible cable that is soldered to the glass. There is a bump where the cable attaches that is typically 0.010" (0.25 mm) high. AccuTouch True-flat touch screens use a flexible printed circuit cable that is attached to the glass using anisotropic film to eliminate the cable bump and enable true flat application.
