    • 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.
    • 一种电子触摸面板包括间隔开的第一传感器板的多元性并在第一方向上布置在第一平面层上。 接近传感器板由间隔开并连接到第一平面层。 接近传感器板具有比所述第一传感器板的多个A更大的表面积。 位置检测电路被配置为电收取第一传感器板在邻近用户对象,以产生电容耦合,并从相对于整个所述第一平面层的第一方向上的用户对象的位置有检测。 位置检测电路被进一步配置成带电接近传感器板,以产生到所述用户对象更高水平的电容耦合的比所述第一传感器板的多元化,并从相对的方向的用户对象的接近远离那里检测 第一平面层。
