IntelliTouch® Surface Acoustic Wave Touch Solutions
Now Powered by
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 has revolutionized SAW technology with eSAW. Built into Elo’s latest 3200 series advanced signal controller, eSAW offers industry leading touch sensitivity of 4x greater than its predecessor.
Combining the enhanced touch performance of eSAW with the benefit of the optical clarity of a clear glass IntelliTouch® SAW touchscreen, yields a high performance touch solution at a price well below that of traditional projective capacitive (PCAP) touchscreen.
The power and sensitivity of eSAW gives new life to Elo’s IntelliTouch SAW touchscreens. Driven by eSAW, the 3200 series controller can upgrade any IntelliTouch screen as a drop in replacement.
IntelliTouch SAW offers zero-bezel style with significantly smaller border width than traditional PCAP screens. 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.
