1. A display device comprising:
a display panel comprising a first part and a second part, wherein the first part comprises a first pixel set, and wherein the second part comprises a first sensor set;
a driving controller configured to control the first pixel set to emit first light when controlling the first sensor set to receive second light, wherein the first sensor set is configured to generate a sensing signal using the second light; and
a readout circuit including at least a readout line to transmit the sensing signal and electrically connected to at least one of the driving controller and the first sensor set and configured to receives the sensing signal,
wherein the readout circuit is configured to calculate a dust concentration using the sensing signal and send the dust concentration to the driving controller.
 
18. A method of operating a display device, the display device comprising a display panel, the method comprising:
emitting first light using a first pixel set disposed in a first part of the display panel;
receiving second light using a first sensor set disposed in a second part of the display panel when the first pixel set emits the first light;
generating a sensing signal using the first sensor set and the second light;
calculating a dust concentration by at least one of a processor, a driving controller, and a readout circuit of the display device based on the sensing signal; and
displaying an image that includes information related to the dust concentration on the display panel,
wherein the readout circuit including at least a readout line to transmit the sensing signal is electrically connected to at least one of the driving controller and the first sensor set and receives the sensing signal.
