Abstract: 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.
