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.

Display controller and display driving apparatus including the same

A display driving circuit comprising a level shift circuit, the level shift circuit including a level shift device configured to receive a source power applied thereto, and to generate an output signal by amplifying an input signal; a power switching circuit configured to provide any one of first to third selection powers as the source power to the level shift device, the first to third selection powers being different from one another; and a switch control circuit configured to change the first selection power to the second or third selection power based on a change of voltage levels of the first to third selection powers.

Display driving circuit and display device including the same

A display driving integrated circuit is provided which drives a plurality of gate lines included in a display panel. The display driving integrated circuit includes: a charge pump configured to change a voltage from an external power source to generate an output voltage; and a gate line driver configured to drive the plurality of gate lines based on the output voltage. The charge pump may operate in one of a low-current mode and a high-current mode based on a size of the display panel.

Integrated circuit for driving adaptable power to display and display device including the same

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.
