Table 8 AccuTouch (resistive) Technology Touchscreen Specifications

Mechanical

Construction

Positional Accuracy

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 Elo-patented separator dots.

Standard deviation of error is less than 0.080 in. (2.03 mm). This equates to less than ±1%.

Touchpoint Density

Touch Activation Force

Surface Durability

More than 100,000 touchpoints/in² (15,500 touchpoints/cm²). Typically less than 4 ounces (113 grams).

Meets Taber Abrasion Test (ASTM D1044), CS-10F wheel, 500 g. Meets pencil hardness 3H.

Expected Life Performance

AccuTouch technology has been operationally tested to greater than

 

35 million touches in one location without failure, using a stylus

 

similar to a finger.

Optical

Light Transmission (per ASTM

D1003)

Visual Resolution

Haze (per ASTM D1003) Gloss (per ASTM D2457)

Typically 75% at 550-nm wavelength (visible light spectrum).

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. Antiglare surface: Less than 15%.

Antiglare surface: 90 ± 20 gloss units tested on a hard-coated front surface.
