AccuTouch Five-Wire Resistive Touchscreens

AccuTouch Zero-bezel

Elo developed AccuTouch technology with the harshest environments in mind, so it is no wonder that it excels in reliability, durability, and expected product life. AccuTouch can withstand environmental conditions such as liquid spills, liquid splashes and washdown, these screens are the most contamination-resistant available. We deliver drift-free operation for a lifetime of 35 million finger touches. Our customers who purchase our AccuTouch components enjoy five-year limited warranty.

Benefits

Five-wire resistive is the most accurate and reliable touchscreen technology. Elo, the inventor of resistive technology, takes five-wire resistive several steps further with its proprietary AccuTouch touchscreens.

  • Stable, accurate, drift-free operation in high-use applications
  • Broad input flexibility and contamination resistance
  • Meet IP65 and NEMA 4/4x/12 standards upon integration
  • Long product life
  • Flat cable attachments for seamless integration and customization capabilities
  • Zero-bezel configuration for seamless design eliminates the traditional bezel that can collect dust and dirt
    • Sleek, elegant "smartphone look" with proven resistive technology for seamless designs that eliminate the traditional bezel
    • Uninterrupted border for easy integration
    • 4H pencil hardness for scratch resistance
    • No lamination of additional décor foil is required which helps to reduce costs and supply chain complexity

Accuracy Over Time

AccuTouch touchscreens enjoy long-term, drift-free operation from industry leading glass substrate processing techniques. The proprietary AccuTouch "Z border" electrode pattern is not only very narrow and produces outstanding linearity, but the frit pattern and drive trace lines are fired into the surface of the glass substrate, becoming stable and permanent after firing. The linearity characteristics of the glass, which establishes the linearity of the touchscreen, will also not change for the life of the product.




AccuTouch Five-Wire Resistive Touchscreens

Durability

An enhanced, scratch-resistant hardcoat gives AccuTouch touchscreens unparalleled protection against damage, even in the harshest industrial environments. AccuTouch True-flat is at the leading edge with its 4H coversheet hardness rating. Elo touchscreens have been operationally tested to over 35 million touches in one location with a stylus similar to a finger, making them ideal for heavy-usage environments.

Contamination Proof

AccuTouch touchscreens are the most contamination-resistant screens available, as they are sealed against contamination and moisture. AccuTouch does not have a permanent venting hole. This prevents fluid ingress through the air vent or along the edges due to capillary action if the outer seal to the display degrades over time.

Optics of AccuTouch

AccuTouch touchscreens provide high light transmission, because the coatings on the glass and coversheet are ITO (indium tin oxide). ITO coatings are extremely transparent and offer the electrical properties required for resistive touchscreens.

Excellent Cable Construction and Attachment

Even the AccuTouch cabling system is unique. It is copper soldered to the fired-on electrode traces pattern, has integral polymer strain relief, uses a copper flex circuit as opposed to ink (extension of coversheet), is low resistance so the cable length does not upset the design of the touchscreen, and importantly, may be folded and creased.

Complete Touch Solution

Screen, controller or chip, software driver TE Touch Solutions develops all Elo screens, controllers, chips, and software drivers in-house and are tested together for optimum performance.

Experience of the Leader in Touch

Elo invented and perfected resistive touchscreens. For nearly 40 years, Elo AccuTouch resistive touchscreen technology has led the industry with the largest application and experience base of any manufacture.

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.
