The gamma voltage supply produces a plurality of gamma voltages. The D/A converter receives the gamma voltages, a first pixel value and a second pixel value, and converts the first pixel value and the second pixel value to a corresponding gamma voltage in the gamma voltages. When the D/A converter converts the first pixel value, the gamma voltages have a first polarity offset.

Therefore, there is no band mura in the panel.
