IntelliTouch Surface Acoustic Wave Technology
Table B-3 IntelliTouch Specifications
Input Method Finger or gloved hand (cloth, leather or rubber) activation.
Mechanical Positional Accuracy Standard deviation of error is less than 2.03 mm (0.080 in).
Equates to less than ±1%.
Touchpoint Density More than 15,500 touchpoints/cm 2 (100,000 touchpoints/in 2 ).
Touch Activation Force Typically less than 85 grams (3 ounces).
Surface Durability Surface durability is that of glass, Mohs’ hardness rating of 7.
Expected Life Performance No known wear-out mechanism, as there are no layers,
coatings, or moving parts. IntelliTouch technology has been
operationally tested to more than 50 million touches in one
location without failure, using a stylus similar to a finger
Sealing Unit is sealed to protect against splashed liquids, dirt, and dust.
Optical Light Transmission (per ASTM D1003) up to 92%
Visual Resolution All measurements made using USAF 1951 Resolution Chart,
under 30X magnification, with test unit located approximately
38 mm (1.5 in) from surface of resolution chart
Clear surface: Excellent, with no noticeable degradation.
Antiglare surface: 6:1 minimum.
Gloss (per ASTM D2457 using a 60- degree gloss meter) Antiglare surface: curved or flat: 95 ± 15 gloss units or 65 ± 15
gloss units; Clear surface: N/A
Environmental Chemical Resistance The active area of the touchscreen is resistant to all chemicals
that do not affect glass, such as:
● Acetone
