Abstract
A driving controller of a display device includes a driving frequency controller for receiving an image signal, determining a driving frequency based on the image signal, and outputting a masking enable signal corresponding to the driving frequency, and an image processor for converting the image signal into a data signal and outputting the data signal, wherein the image processor sequentially converts, based on the masking enable signal being at an active level, a part of bits of the image signal into the data signal corresponding to a plurality of dither patterns.
