Abstract:
1. A backlight driving system for a liquid crystal display, the system comprising: a power supply unit for converting first alternating current (AC) power into direct current (DC) power having a voltage level; an inverter unit for converting the DC power from the power supply unit into second AC power at a one-to-one conversion ratio; a boosting unit for boosting the second AC power from the inverter unit into lamp lighting power; and at least one lamp for receiving the lamp lighting power from the boosting unit to emit light, wherein the inverter unit comprises: a switch for switching the DC power transmitted from the power supply unit; and a one-to-one transformer having a one-to-one winding ratio corresponding to the one-to-one voltage conversion ratio for converting the power switched by the switch into AC power having substantially the same voltage level as the voltage level of the DC power.
