News editors obtained the following quote from the background information suppli ed by the inventors:“A resistive touch screen may be constructed of layers of f lexible plastic and glass coated with conductivematerial. When a user applies p ressure to the screen, resistance between the layers changes. This can beused t o identify where the user pressed. Instead of a difference in resistance, a capa citive touch screenuses a conductive touch of a human finger (or a specialized device) as input. When a capacitive touchscreen is touched by the user, a small electrical charge is drawn to the point of contact. This allows thedisplay to detect where it has received an input. The result is a display that can detect l ighter touchesand with greater accuracy than a resistive touchscreen.”
