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
