摘要 |
A lamp driving apparatus of a liquid crystal display device includes m lamp groups in which a plurality of lamps generating light are disposed; n (n<m) inverter parts to generate an AC voltage for driving the lamps; an inverter controller to control the inverter parts; and a multiplexer to selectively supply the AC voltage generated at the n inverter parts to the n lamp groups among the m lamp groups.
