Abstract
A capacitive touch keyboard includes a soft shielding layer, a soft intermediate layer, and a one dimensional sensor layer where the soft intermediate layer is interposed between the other two to form a capacitor structure. The soft shielding layer includes a ground plane, a dielectric material covering on the ground plane, and plural key areas at its outer surface. The one dimensional sensor layer includes plural sensing cells which correspond to the key areas, and respective cells are electrically connected to a capacitance sensing circuit. Therefore, features of more compact size, simplified structure design, and tactile feel are provided in a capacitive keyboard.
