AccuTouch Touchscreen Specifications
Mechanical
Construction Top: Polyester with outside hard-surface coating with clear or antiglare finish.
Inside: Transparent conductive coating.
Bottom: Glass substrate with uniform resistive coating. Top and bottom layers
separated by patented separator dots.
Positional Accuracy Standard deviation of error is less than 0.080 in. (2.03 mm). This equate s to le ss
than ±1%.
Touchpoint Density More than 100,000 touchpoints/in2 (15,500 touchpoints/cm2).
Touch Activation Force Typically less than 4 ounces (113 grams).
Surface Durability Meets Taber Abrasion Test (ASTM D1044), CS-10F wheel, 500 g. Meets pencil
hardness 3H.
Expected Life AccuTouch technology has been operationally tested to greater than 35 million
Performance touches in one location without failure, using a stylus similar to a finger.
Optical
Light Transmission Typically 85% at 550-nm wavelength (visible light spectrum).
(per ASTM D1003)
Visual Resolution All measurements made using USAF 1951 Resolution Chart, under 30 X
magnification, with test unit located approximately 1.5 in. (38 mm) from surface
of resolution chart.
Antiglare surface: 6:1 minimum.
Haze (per ASTM D1003) Antiglare surface: Less than 15%.
Gloss (per ASTM D2457) Antiglare surface: 90 ± 20 gloss units tested on a hard-coated front surface.
