Table 7 IntelliTouch (surface acoustic wave) Technology
Touchscreen Specifications
Mechanical
Positional Accuracy
Standard deviation of error is less than 0.080 in. (2.03
mm). Equates to less than ±1%.
Touchpoint Density
More than 100,000 touch points/in2 (15,500 touch
points/cm2).
Touch Activation Force
Typically less than 3 ounces (85 grams).
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)
90%
Visual Resolution
All measurements made using USAF 1951 Resolution
Chart, under 30X magnification, with test unit located
approximately 1.5 in (38 mm) 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: 60 ± 20 gloss units or 75 ± 15
gloss units.
Environmental
Chemical Resistance The active area of the touchscreen is resistant to all
chemicals that do not affect glass, such as:
Acetone, Toluene, Methyl ethyl ketone, Isopropyl
alcohol, Methyl alcohol, Ethyl acetate, Ammonia-based
glass cleaners, Gasoline, Kerosene, Vinegar
Electrostatic Protection
(per EN 61 000-4-2, 1995)
Meets Level 4 (15 kV air/8 kV contact discharges).
