6. How ClearTek™ II Works
1 Small amount of voltage is applied to the four corners of the touch screen.
3 The x,y location of the point of contact is calculated by the EX II controller and transmitted to the PC.
2 A finger touches the screen and draws a minute amount of current to the point of contact.
4 EX II Electronics provide tailored firmware and fast, accurate touch.

ClearTek II has Low Surface Energy, which means:
Easy-glide, smoother surface to the touch
Increased scratch resistance – harder for an object to catch on the surface
Easier to clean – lower contaminant adhesion due to lower surface energy
Liquids bead up and roll off screen
Glass Surface High surface energy inhibits finger from dragging smoothly
ClearTek™ II Low surface energy drags easily
