Abstract
A display device includes a display substrate having a non-display area at least partially surrounding a display area, and pixels in the display area, and a sensor substrate covering the pixels and a portion of the display substrate. The display device also includes first and second pads in the non-display area, a first sensor on the sensor substrate, a first sensor line connecting the first pad and the first sensor, and a second sensor line connecting the second pad and the first sensor. In addition, the display device includes a sensor transmitter to supply a sensing signal to the first pad during a first period, and a sensor receiver to receive a sampling signal from the second pad during a second period after the first period.
