IntelliTouch 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 touchpoints/in2 (15,500 touchpoints/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	90%
D1003)
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.
	Antiglaresurface:6:1minimum.
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
