IntelliTouch® Surface Acoustic Wave Touch Solutions
Elo first introduced Surface Acoustic Wave (SAW) touch technology in 1987. SAW touchscreen technology delivers superior image clarity, resolution, light transmission, and reliability because it utilizes clear glass that continues to work even if scratched. There are no coatings, plastic films or moving parts to wear out or be damaged. The active area of the touchscreen is resistant to chemicals such as acetone, toluene, methyl ethyl ketone, isopropyl alcohol, methyl alcohol, ethyl acetate, ammonia-based glass cleaners, gasoline, kerosene, and vinegar.
Elo offers IntelliTouch SAW technology with transactional single touch or interactive multi-touch capabilities. Micro-bezel or zero-bezel designs are offered along with fully tempered, heat or chemically strengthened glass for ruggedized applications. IntelliTouch technology has met all the Additional Qualification (AQ) testing requirements established by Microsoft for Windows 7 multi-touch touch gesture recognition.
IntelliTouch SAW is a cost-effective alternative to projected capacitive (PCAP) touch technology that offers better optical clarity and the same zero-bezel style with significantly smaller border width. Three axes of touch information are used to precisely discern two simultaneous touch locations anywhere on the screen. IntelliTouch solutions offer a simple bill of material, a less complex manufacturing and touchscreen integration process, and less capital investment than PCAP technologies.
Customization capabilities include logos, clear icons, border buttons, and other enhancements can be added during the design cycle. IntelliTouch can scale across a wide range of screen sizes, without performance degradation. The stable, drift-free operation of SAW touchscreen technology provides an accurate touch response measured on three axes using a finger, gloved hand, or passive stylus. Elo’s sensitive touch response recognizes location and amount of pressure applied. Elo has tested IntelliTouch touchscreens to more than 50 million touches in one location without failure, using a stylus simulating a finger. The graphics quality and colors of HD resolution software applications are preserved based on the optical clarity of SAW clear glass touch technology.
