Elo TouchSystems Introduces Brightest, Most Durable Resistive Touchscreen on the Market

For Release

January 3, 1995

Oak Ridge, Tenn.

Elo TouchSystems Inc. today is introducing the brightest, most durable resistive touchscreen on the market for rugged environments, including restaurants, factories, hospitals, and point-of-sale counters. The AccuTouch HL™ Series resistive touchscreen couples Elo TouchSystems’ rugged and reliable five-wire resistive technology with a touchscreen that is 36 percent brighter than previous touchscreens. The result is a new “high light” transmission touchscreen for liquid crystal and other flat panel displays.

“We’ve worked closely with suppliers, customers, and flat panel manufacturers to develop the brightest, most durable resistive touchscreen available to original equipment manufacturers,” says Daniel Shore, AccuTouch product marketing manager. “The new AccuTouch HL series touchscreen, with more than 75 percent light transmission, addresses the industry’s need for brighter and clearer touchscreen images over LCD and other flat panel displays.”

Like many UV and contrast-enhancing filters on the market for cathode ray tubes, AccuTouch resistive touchscreens were originally designed with light transmission in the 55 to 60 percent range to provide optimum optical performance. But for the fast-growing LCD and flat panel display markets, the need for UV-filtering and contrast enhancement has been surpassed by the need for higher brightness. Therefore, in addition to Elo TouchSystem’s original AccuTouch curved touchscreen for CRTs, the AccuTouch HL series touchscreen for flat panel displays will be available to provide this higher light transmission feature.

Enhanced Brightness, Unmatched Durability

The enhanced light transmission and brightness of the new AccuTouch HL series is made possible through the touchscreen’s advanced material science technology. AccuTouch HL touchscreens have one layer of an advanced light-transmission, scratch-resistant plastic that is tightly laminated to one layer of optics-grade glass. These serve to preserve the display’s image quality and purity. In contrast, the older four-wire resistive touchscreens typically have many layers of materials: a glass or plastic backing to provide rigidity, a layer of adhesive, and two loosely attached layers of plastic. The extra layers of plastic and adhesive degrade the optical performance of the four-wire resistive touchscreen.

The extreme durability of the AccuTouch HL touchscreen is also related to its state-of-the-art resistive technology. Conventional four-wire resistive touchscreens are vulnerable to accuracy problems as their electrical integrity deteriorates with heavy usage. Five-wire touchscreens are up to ten times more durable than four-wire touchscreens and will continue to operate reliably in spite of heavy use. This, along with their gloved-hand activation capability, makes five-wire touchscreens particularly suitable for point-of-sale, medical, and industrial applications. Like all AccuTouch touchscreens, the AccuTouch HL series touchscreen can be gasket-sealed for applications in wet and dirty environments.

The new product is available with serial, PC-Bus, and chip-based controller options. Standard sizes are available to cover popular liquid crystal and flat panel displays. Custom sizes are available upon request.
