Abstract
A method and apparatus for generating gradation voltages are provided. Maximum and minimum reference voltages are selected from a distribution of voltages ranging from a first source voltage to a second source voltage. The maximum reference voltage is selected as a 1gradation voltage and the minimum reference voltage is selected as an Ngradation voltage, or vice versa, in response to an inversion control signal, where N is a natural number. First to Mgamma voltages are selected from among a plurality of voltages generated by a voltage distribution between the 1gradation voltage and the Ngradation voltage. Second to (N−1)gradation voltages are generated from a voltage distribution between the 1gradation voltage and the Ngradation voltage, using the 1gamma voltage to the Mgamma voltage, where M is a natural number.
