Abstract
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 including: a master gray scale voltage generation circuit configured to divide a reference voltage to generate tap voltages, and to generate a first low-power mode gray scale voltage based on at least one of the tap voltages; and a first low-power mode amplifier configured to drive the first group of pixel lines based on the first low-power mode gray scale voltage.
