Abstract
A method for adjustable outputting Gamma reference voltages includes generating a polarity control signal corresponding to one of plural predetermined display panel types, where a plurality of polarity control signals corresponding to the panel types of the plurality of display panels are different; generating a polarity signal corresponding to the display panel according to the polarity control signal; and generating and outputting a plurality of Gamma reference voltages according to the polarity signal. The plurality of Gamma reference voltages include a positive polarity Gamma reference voltage set and a negative polarity Gamma reference voltage set, and a voltage number of the positive polarity Gamma reference voltage set is the same as a voltage number of the negative polarity Gamma reference voltage set.
