ABSTRACT:
A drive circuit for driving scanning lines or data lines in an EL or plasma display panel has a pair of power recovery lines each connected to a corresponding one of two thyristors. The first thyristor recovers electric power from the scanning line and the second thyristor supplies the electric power to another scanning line. The lower ON-resistance and lower parasitic capacitance of the thyristors provides an efficient recovery of the electric power while suppressing a latch-up failure of CMOSFETs.
