Patent attributes
A display device includes: a plurality of pixels connected to power lines to which a pixel driving voltage and a reference voltage are applied, a plurality of data lines to which data voltages of pixel data of an input image are applied, and a plurality of gate lines to which a gate signal is applied; a display panel driver configured to write the pixel data of the input image to the plurality of pixels during a display mode of the display device and to write preset sensing data to the plurality of pixels during a sensing mode of the display device; and a sensing unit configured to simultaneously sense the plurality of the pixels by measuring a current flowing through a first power line from the plurality of power lines to which the pixel driving voltage is applied to the plurality of pixels during the sensing mode.
