Abstract: A display controller comprises a buffer configured to store first pixel data input to a source line during a first period, and second pixel data input to the source line during a second period, subsequent to the first period, and a data generating unit configured to generate control data by comparing each of the first pixel data and the second pixel data with desired reference data, and transfer the second pixel data and the control data to a source driver driving the source line.

Abstract: A data generator includes an over drive data generator and a buffer. The over drive data generator generates an over drive data based on a previous display data and a current display data. The buffer provides the previous display data to the over drive data generator. The buffer stores the current display data and the over drive data. The buffer outputs the current display data and the over drive data. The data generator may increase the speed of driving the load connected to a display driver using the over drive voltage corresponding to the over drive data. If the speed of driving the load connected to the display driver is increased, the operational speed of the display device may be increased.
