A display apparatus for a vehicle includes: an organic light emitting panel; a gray level calculating unit configured to calculate a gray level of the organic light emitting panel; a temperature detecting unit configured to detect a temperature of the organic light emitting panel; and a processor configured to divide the organic light emitting panel into a plurality of blocks, divide the plurality of blocks into a plurality of sub-blocks smaller than the plurality of blocks, calculate a luminance reduction amount per unit time of the plurality of sub-blocks, based on gray level information of the sub-block calculated by the gray level calculating unit and temperature information of the organic light emitting panel detected by the temperature detecting unit, and calculate a time point of degradation compensation of the organic light emitting panel, based on the luminance reduction amount per unit time of the plurality of sub-blocks.
