Abstract
A display apparatus includes a signal receiver configured to receive an image signal having a plurality of gradations; a display configured to display an image based on the received image signal; a storage configured to store a plurality of calibration coefficients corresponding to more than two gradations from among the plurality of gradations to calibrate a uniformity of the image; and a controller configured to control the display to apply to the received image signal, a calibration coefficient corresponding to a gradation of the received image signal from among the plurality of gradations to display the image. With this, the uniformity of the image outputted from the display apparatus is exactly calibrated with respect to the plurality of gradations.
