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.

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.
