<p>A touch screen of the voltage-divider type is provided which includes two substrates (122, 124) spaced apart from each other by a gap, each substrate including a region formed of conductive material formed in overlapping relationship to each other. A pair of strips (50, 130 and 52, 138) formed from a resistive material is coupled to opposed edges of each conductive region such that the resistance strips (50, 130) of the first substrate (122) extending in a substantially perpendicular direction to the resistance strips (52 and 138) of said the second substrate (124). A circuit (142) is provided which applies a first reference voltage across the resistance strips (50, 130) of the first substrate (122), and subsequently applies a second reference voltage across the resistance strips (52, 138) of the second substrate (124).</p> |
