Classification: CPC G | IPC G

Claim 15:
16. A display device, comprising:
a display panel including first through N-th pixel rows, where N is an integer greater than 1; 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 an average panel luminance level 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 (K+1)-th through the N-th pixel rows received in a previous frame period, and to determine a scale factor for the (K+1)-th pixel row based on the average panel luminance level, where K is an integer greater than 0 and less than or equal to N; and
a data correction circuit configured to correct the (K+1)-th line data for the (K+1)-th pixel row based on the scale factor in the current frame period,

wherein the scale factor is determined when the K-th line data for the K-th pixel row among the first through N-th pixel rows are received in the current frame period.
