Abstract: A display device including: a display panel including first through N-th pixel rows; and a panel driver configured to sequentially receive first through N-th line data for the first through the N-th pixel rows in each frame period, and to drive the display panel based on the first through the N-th line data, the panel driver including: a current control circuit configured to determine a current control value for a (K+1)-th pixel row based on the first through K-th line data for the first through K-th pixel rows received in a current frame period and (K+1)-th through the N-th line data for the (K+1)-th through the N-th pixel rows received in a previous frame period; and a data correction circuit configured to correct the (K+1)-th line data for the (K+1)-th pixel row based on the current control value in the current frame period.
