Capacitive Technology for LCDs
Elo capacitive touchscreens (also called surface capacitive) have a transparent protective coating that makes the sensor resistant to scratches and abrasions. Touch performance is unaffected by everyday abuse and mishaps such as dirt, dust, condensation, liquid spills, contaminants or cleaning solutions. And the Elo-designed controller responds to quick, light touches, and operates drift-free even in areas of poor grounding.
