iTouch Plus
iTouch Plus Surface Acoustic Wave (SAW) Touchscreen couples zero-bezel design with multi-touch functionality. iTouch Plus technology has passed the Microsoft Windows 7 Multi-touch additional qualification (AQ) testing requirements. It is the result of optimizing a trusted technology —SAW—to enhance industrial design, touch performance and reliability, ease of touchscreen system integration, and bill of material cost. The iTouch zero-bezel SAW offers the ability to realize a seamless, flat, frameless design that can be coupled with customization capabilities where logos, clear icons and other enhancements can be added during the design cycle. Industrial designers are no longer limited by a bezel or frames that are inherent in other touch technologies such as camera or optical touch.
iTouch Plus solutions offer a simple bill of material, a less complex manufacturing and touchscreen integration process, and less capital investment than projective capacitive technologies. This results in a more cost competitive touchscreen solution. The electronics can scale across a wide range of screen sizes, without performance degradation, which contributes to the iTouch Plus touchscreen technology being the choice of selection without concern of designin touch performance issues. iTouch Plus is based on SAW technology which is proven in the industry as reliable touch technology for long-life applications with a near zero field return rate on touch technology related issues. This new technology is available today to OEMs who are looking for a reliable, frameless, cost competitive custom touchscreen solution.

Acoustic Pulse Recognition (APR)
Elo’s Acoustic Pulse Recognition (APR) touchscreens use a completely new and unique way of sensing touches on a display. Consisting only of a glass overlay mounted in front of the display, together with a small electronic controller board, Elo’s APR technology provides a new set of benefits that have only been partially achieved before by other touch technologies.
APR combines the ultimate in optical qualities, durability, and stability of surface wave (SAW) and infrared technologies, with the excellent dragging properties of capacitive, along with stylus, glove and fingernail activation, and low cost advantages of resistive technology. In addition, it is resistant to water and other contaminants on the screen, can be scaled from PDA to 42-inch displays, and provides palm rejection during signature capture.
As with many of the best inventions in history, APR works in a simple and elegant way—by recognizing the sound created when the glass is touched at a given position. Elo TouchSystems, the global leader in resistive and acoustic touch technology for over 35 years, is expanding APR technology across a wide range of markets and applications.
