Abstract: A display device includes pixels, an auxiliary pixel, a controller, and an emission driver. The pixels are coupled to data lines and emission control lines. The auxiliary pixel is coupled to an auxiliary data line and auxiliary emission control lines. The controller is configured to measure an auxiliary current supplied from the auxiliary pixel through an auxiliary line, and to control a width of an emission start signal based on an accumulation amount of the auxiliary current. The emission driver is configured to, based on the emission start signal, supply emission control signals to the pixels and the auxiliary pixel through the emission control lines and the auxiliary emission control lines.
