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%.

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.

AccuTouch technology has been operationally tested to greater than 35 million touches in one location without failure, using a stylus similar to a finger.
