Abstract: According to one embodiment, a sensor-equipped display device includes a display panel, a detection electrode, a conductive member arranged at intervals from the display panel and the detection electrode, and controller. In a first sense period, the controller drives a common electrode of the display panel or the detection electrode and extracts input position data from the detection electrode. In a second sense period, the controller drives the conductive member and extracts first input pressure data from a first electrode, the controller drives a second electrode and extracts second input pressure data from the conductive member, or the controller drives a third electrode and extracts third input pressure data from the third electrode.
