Claim 12:
13. A display device comprising:
a display panel comprising a first group of pixel lines connected to a first group of pixels, and a second group of pixel lines connected to a second group of pixels; and
a column driver integrated circuit (IC) module comprising a first column driver IC connected to the first group of pixel lines and a second column driver IC connected to the second group of pixel lines,
wherein the first column driver IC comprises:
a first master gray scale voltage generation circuit configured to divide a first reference voltage to generate first tap voltages, and to generate a first low-power mode gray scale voltage based on at least one of the first 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 first tap voltages; and
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 first column driver IC.
