ABSTRACT:
An inverter for a liquid crystal display and its driving method are disclosed. The inverter includes: a DC/AC converting unit that converts DC power supplied from a voltage source into AC power; a transformer that converts the AC power supplied from the DC/AC converting unit into a high voltage AC; and a frequency controller that determines the frequency of an output of the DC/AC converting unit such the output of the DC/AC converting unit has an initial driving frequency during an initial driving time that beings upon initiating driving of the liquid crystal panel and such that that the output of the DC/AC converting unit has a normal driving frequency larger than the initial driving frequency after the initial driving time.
