Abstract
A display driving device for improving the definition of an image according to one aspect of the present invention includes a brightness calculator for calculating first brightness data corresponding to a first resolution and second brightness data corresponding to a second resolution less than the first resolution using input image data, an offset calculator for calculating an offset on the basis of the first brightness data and the second brightness data, an input image converter for converting the input image data into input image data to which the calculated offset has been applied, a first data output unit for generating output image data for a first panel using the converted input image data and outputting the generated output image data, and a second data output unit for generating output brightness data for a second panel using the second brightness data and outputting the generated output brightness data.
