ABSTRACT:
A problem arises with related art liquid crystal displays in that the amount of power consumed will not be reduced any further, as a voltage generator circuit to supply power is kept activated. An exemplary method for driving a display uses a first plurality of operational amplifiers to generate a first plurality of voltages of different levels associated with a first plurality of grayscale levels displayable in the display so as to provide the display with a second plurality of grayscale levels out of the first plurality of grayscale levels. The method includes activating a second plurality of operational amplifiers corresponding to the second plurality of grayscale levels out of the first plurality of operational amplifiers, and deactivating remaining operational amplifiers other than the second plurality of operational amplifiers.
