Circuit and method for driving a flat panel display

摘要

A drive circuit includes: an output line (OUTCY)connected to one end of a load (20); a first signal line (OUTAY)for supplying a first potential (Us) higher in potential than a reference potential; a second signal line (OUTBY)for supplying a second potential lower than the reference potential and a third potential still lower than the second potential; and a potential supply circuit connected to the first signal line for supplying a fourth potential(-Vy) lower than the reference potential to the first signal line, wherein a potential of the second signal line connected to the first signal line via a capacitor (CY1) is made to be a third potential by supplying the fourth potential lower than the reference potential to the first signal line so that the third potential is supplied to the capacitive load from the second signal line.
