摘要: A driving apparatus for a display is provided. The driving apparatus for a display comprises: a digital/analog converter for receiving an input voltage lower than a source voltage used in a buffer amplifier for output driving, generating a plurality of reference voltages, and selecting a reference voltage corresponding to an M (M is a positive integer) bit data signal; and an amplifier for amplifying the reference voltage selected by the digital/analog converter. Therefore, a circuit area and power consumption of the driving apparatus for a display can be minimized.
