1. A display device comprising:
a display panel comprising scan lines, emission control lines, a readout line, and a reset control line;
a scan driver configured to provide scan signals to the scan lines;
an emission driver configured to provide emission control signals to the emission control lines; and
a readout circuit configured to receive a sensing signal from the readout line in response to the scan signals,
wherein the display panel further comprises:
a first pixel in a first row of a display area, and connected to a first sub-scan line from among the scan lines, and a first emission control line from among the emission control lines;
a first photo sensor in the first row, and connected to the first sub-scan line, the reset control line, and the readout line;
a second pixel in a second row of the display area, and connected to a second sub-scan line from among the scan lines, and a second emission control line from among the emission control lines; and
a second photo sensor in the second row, and connected to the second sub-scan line, a third emission control line from among the emission control lines, and the readout line, and
wherein the third emission control line is configured to transmit an emission control signal from among the emission control signals to a gate electrode of a sub-sensor transistor of the second photo sensor, the gate electrode being connected to the third emission control line.
