摘要： Disclosed is a display driving apparatus. The display driving apparatus includes a distance calculator configured to calculate, for a plurality of pixels constituting a frame input to a display panel, distances between respective pixels and a central pixel, a gain calculator configured to divide the frame constituted by the plurality of pixels into an interest area and a non-interest area using the distances between respective pixels and the central pixel, and to determine a gain of each pixel in accordance with an area where the pixel is disposed, and a gain applier configured to generate pixel data using the gain of each pixel. Gains of the pixels disposed in the interest area have a constant value. Gains of the pixels disposed in the non-interest area are decreased in proportion to distances between the pixels in the non-interest area and the central pixel, respectively.
