Abstract: An electronic touch panel includes a plurality of spaced apart first sensor plates that are arranged in a first direction on a first planar layer. A proximity sensor plate is spaced apart from and attached to the first planar layer. The proximity sensor plate has a greater surface area than a plurality of the first sensor plates. A position detection circuit is configured to electrically charge the first sensor plates to generate capacitive coupling to an adjacent user object and to detect therefrom a location of the user object relative to the first direction across the first planar layer. The position detection circuit is further configured to electrically charge the proximity sensor plate to generate a higher level of capacitive coupling to the user object than a plurality of the first sensor plates and to detect therefrom a proximity of the user object relative to a direction away from the first planar layer.
