ABSTRACT:
The grayscale voltage generation device includes a first line, a second line and a plurality of serial digital analog converters (DACs). A first reference voltage having a first voltage value is supplied to the first line, and a second reference voltage having a second voltage value is supplied to the second line. Each of the plurality of serial DACs receives grayscale information representing a grayscale level and generates a grayscale voltage having a voltage value corresponding to the grayscale information using the reference voltages supplied to the first and second lines.
