SENSOR-EQUIPPED DISPLAY DEVICE
First Claim
1. A sensor-equipped display device comprising:
- a display panel comprising a first electrode, a second electrode spaced apart from the first electrode and extending in parallel to the first electrode, and a detection electrode;
a first driver configured to deliver a common driving signal to the first electrode and the second electrode at a time of display driving for displaying an image, and to selectively write a write signal to one of the first electrode and the second electrode at a time of sensing driving for executing sensing; and
a second driver configured to read, 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.

Abstract
According to one embodiment, a 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.

9. A sensor-equipped display device comprising:
-
a display panel comprising a first electrode group formed in a comb shape and including a plurality of first electrodes extending in a first direction in a display area which displays an image, and spaced apart from each other in a second direction crossing the first direction, and a first connection electrode provided in a first non-display area and connected to the first electrodes, a second electrode group formed in a comb shape and spaced apart from the first electrode group, the second electrode group including a plurality of second electrodes extending in the first direction in the display area and spaced apart from each other in the second direction, and a second connection electrode provided in a second non-display area on a side opposite to the first non-display area with the display area interposed, and connected to the second electrodes, and a detection electrode, the first electrodes and the second electrodes being alternately arranged in the second direction; a first driver configured to deliver a common driving signal to the first electrode group and the second electrode group at a time of display driving for displaying an image, and to selectively write a write signal to one of the first electrode group and the second electrode group at a time of sensing driving for executing sensing; and a second driver configured to read, from the detection electrode, a read signal indicative of a variation of a sensor signal occurring between the one of the first electrode group and the second electrode group, on one hand, and the detection electrode, on the other hand, at the time of the sensing driving. - View Dependent Claims (10, 11, 12, 13, 14, 15)
