Abstract
A display apparatus includes: a display panel configured to display an image frame; an arithmetic operator configured to divide the image frame into blocks, calculate a pixel gradation value of the pixel blocks, and accumulate the calculated pixel gradation values; and a compensator configured to locally reduce a luminance of a corresponding pixel block, of which a respective accumulated pixel gradation value exceeds a threshold value of among the plurality of pixel blocks, and to compensate for a luminance difference between the corresponding pixel block, for which the luminance has been reduced, and surrounding pixel blocks. Accordingly, it is possible to effectively remove an afterimage.
