Claim 0:
1. A display device comprising:
a plurality of pixels that are connected to a power line to which a pixel driving voltage is supplied, the plurality of pixels divided into a plurality of columns of pixel blocks that extend along a first direction and each pixel block including a different subset of pixels from the plurality of pixels where the different subset of pixels in the pixel block are arranged in a plurality of columns of pixels within the pixel block,
a plurality of data lines that extend in the 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 respective subset of pixels included in each pixel block included in a column of pixel blocks from the plurality of columns of pixel blocks during the sensing mode, each of the respective subset of pixels included in each pixel block is supplied the sensing data during the sensing mode and at least one light emitting element included in a pixel from the respective subset of pixels that are arranged in the plurality of columns of pixels is configured to receive the sensing data but not emit light during the sensing mode.
