Abstract:
1. A backlight inverter system comprising: a pulse generator for generating a first pulse to start a backlight lamp, the pulse generator generating a second pulse for a normal operation after the backlight lamp is started; a high voltage generator for generating a high frequency voltage corresponding to the pulses output from the pulse generator and for applying at least one of a predetermined level of start-up voltage and a normal voltage to the backlight lamp; a start-up voltage adjuster for adjusting the level of start-up voltage applied to the backlight lamp; and a lamp driving detector for detecting if the backlight lamp is started and for outputting a corresponding signal to the pulse generator to generate the second pulse if the lamp is started, and for detecting if the backlight lamp is not started and for outputting a corresponding signal to the start-up voltage adjuster to increase the level of the start-up voltage if the lamp is not started.
