Abstract

According to one embodiment, a sensor device includes a panel and a control circuit. The panel includes an insulating layer, a first electrode, and a second electrode. The control circuit including a first circuit including a timing control circuit and a first amplifier, and a second circuit including a detection circuit connected to a floating ground line. During a first sensing drive period, the first output unit outputs a first synchronization signal, the timing control circuit outputs a second synchronization signal, the first amplifier provides the amplified second synchronization signal to each of the floating ground line and the first electrode, and the detector reads a change in a sensor signal.
