A display driver integrated circuit (IC) includes a grayscale voltage generator, a main decoder unit, a pre-decoder unit, and an output buffer unit. The grayscale voltage generator is configured to receive at least one gamma reference voltage and generate a plurality of grayscale voltages. The main decoder unit is configured to receive the grayscale voltages and data, decode the data, and selectively output a grayscale voltage based on the decoded result. The pre-decoder unit is configured to decode part of the data and output a precharge voltage. The output buffer unit is configured to sequentially receive an output of the pre-decoder unit and an output of the main-decoder unit, and output grayscale data used for driving a display device.
