Abstract: A detection device includes: a first electrode extending in a first direction along a detection face; a plurality of second electrodes extending in a second direction along the detection face, and facing the first electrode; a signal output circuit configured to output a signal to the first electrode; a detection circuit that detects capacitance generated between the first electrode and the second electrodes in accordance with the signal; and a force-sensing element configured to detect force applied to the detection face. A plurality of first electrode blocks each including a plurality of the first electrodes are arranged in the second direction. The signal output circuit is switched between a first mode of outputting the signal to the first electrode blocks at different times and a second mode of outputting the signal to some of the first electrodes and starts operation on the second mode when the force is detected.

Abstract: According to one embodiment, a sensor includes a panel. The panel includes a cell having a detection surface and a non-detection surface, and a support substrate formed of resin and bonded to the non-detection surface of the cell. The cell includes an insulating substrate formed of resin and having a first surface and a second surface, a first protective layer facing the second surface of the insulating substrate, and a sensor electrode disposed between the insulating substrate and the first protective layer. A thickness of the support substrate is greater than a thickness of the insulating substrate, and is greater than a thickness of the first protective layer.
