1. A column driver integrated circuit (IC) which drives a first group of pixel lines connected to a first group of pixels included in a display panel, and a second group of pixel lines connected to a second group of pixels included in the display panel, the column driver IC comprising:
a master gray scale voltage generation circuit configured to:
divide a reference voltage to generate tap voltages, and
generate a first low-power mode gray scale voltage based on at least one of the tap voltages;
a plurality of first source amplifiers configured to drive the first group of pixel lines based on gray scale voltages corresponding to the tap voltages;
a first low-power mode amplifier separated from the plurality of first source amplifiers and configured to drive the first group of pixel lines based on only the first low-power mode gray scale voltage; and
a first pin configured to provide the first low-power mode gray scale voltage to an outside of the column driver IC.
