摘要:
A power supply apparatus capable of reducing power consumption and a liquid crystal display including the power supply apparatus includes a first DC-AC converting unit (250) enabled by a driving signal (CONT) to convert a DC voltage into a first AC voltage, increase the first AC voltage, and supply the increased first AC voltage as a first power supply voltage (Vac_1); a switching unit (260) which selectively transmits the driving signal (CONT) in response to a selection signal (SEL); and a second DC-AC converting unit (270) enabled by the driving signal (CONT) selectively transmitted by the switching unit (260) to convert the DC voltage into a second AC voltage, increase the second AC voltage, and supply the increased second AC voltage as a second power supply voltage (Vac_2).
