ABSTRACT:
A display apparatus includes a display panel having display devices arranged in a matrix layout and driven through a plurality of row wirings and column wirings, a scanning unit to scan the row wirings, and a modulation unit to supply a modulation signal to the column wirings. A compensation unit applies compensation processing to compensate for fluctuation of display luminance due to the influence of voltage drop caused by a resistance of the row wiring to the image data, and a luminance control unit controls display luminance of the display panel based upon luminance information of the image data.
