Claim 5:
6. A column driver integrated circuit (IC) module comprising:
a first column driver IC configured to drive a first group of pixel lines included in a display panel; and
a second column driver IC configured to drive a second group of pixel lines included in the display panel,
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;
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.
