Abstract: According to an aspect of the present disclosure, the display device includes a timing controller configured to output a power control signal for controlling a driving current to the data driver. The data driver includes a plurality of source driving integrated circuits (SDICs) which each supplies the data voltage to each of the plurality of active areas. The timing controller generates the power control signal depending on a difference value between comparison data which is the maximum data transition value between adjacent pixel rows disposed in each of the plurality of active areas and edge comparison data which is the maximum data transition value between adjacent pixel rows disposed in the plurality of edge active areas. Thus, it is possible to improve an image quality at a boundary between the active areas.
