Abstract
A pressure sensing unit, a capacitive hybrid sensor device, and an input apparatus using the same are provided. The pressure sensing unit for detecting pressing events includes a pressure sensing pad group and a floating conductive element. The pressure sensing pad group includes a first pressure sensing pad, a second pressure sensing pad, and a ground pad that are spaced apart from one another. The first and second pressure sensing pads are electrically shielded from each other by the ground pad. One among the floating conductive element and the pressure sensing pad group is configured to be movable in a movement direction relative to another one among the floating conductive element and the pressure sensing pad group. The floating conductive element overlaps with the pressure sensing pad group in the movement direction. Therefore, a signal-to-noise ratio can be increased and an erroneous detection can be prevented.
