Abstract
According to one embodiment, sensor-equipped display device includes a display panel, a first driver, and a second driver. The display panel includes a first electrode, a second electrode and a detection electrode. The first driver delivers a common driving signal to the first electrode and the second electrode at a time of display driving, and selectively writes a write signal to one of the first electrode and the second electrode at a time of sensing driving. The second driver reads, from the detection electrode, a read signal indicative of a variation of a sensor signal occurring between the one of the first electrode and the second electrode, on one hand, and the detection electrode, on the other hand, at the time of the sensing driving.
