Classification: CPC G | IPC G

Claim 10:
11. A display device comprising:
a plurality of pixels that are connected to a power line to which a pixel driving voltage is supplied;
a plurality of data lines that extend in a first direction and are connected to the plurality of pixels, the plurality of data lines applying a plurality of data voltages of pixel data of an image to the plurality of pixels;
a plurality of gate lines that are connected to the plurality of pixels and extend in a second direction that intersects the first direction, the plurality of gate lines applying gate signals to the plurality of pixels;
a data driver configured to supply the plurality of data voltages of the image to the plurality of data lines during a display mode, and to supply sensing data to the plurality of data lines during a sensing mode;
a gate driver configured to supply the gate signals to the plurality of gate lines; and
a sensing circuit configured to sense current flowing through the power line that is connected to a subset of pixels from the plurality of pixels during the sensing mode, the subset of pixels arranged in a plurality of of columns of pixels along the first direction and at least one light emitting element included in a pixel from the subset of pixels is configured to receive the sensing data but not emit light during the sensing mode.
