Abstract
A display device including: scan lines including first and second scan lines; pixels connected to the scan lines; photo sensors connected to some of the scan lines, the photo sensors including a first photo sensor connected to the first scan line and a readout line, and a second photo sensor connected to the second scan line and the readout line; a scan driver to provide scan signals to the scan lines; and a readout circuit to receive, through the readout line, detection signals which are outputted from the photo sensors in response to the scan signals, wherein, while the scan signals are provided to the first and second scan lines, the readout circuit samples a detection signal of one of the first photo sensor and the second photo sensor without sampling a detection signal of the other one of the first photo sensor and the second photo sensor.
