ABSTRACT:
A backlight inverter system and a start-up control method thereof to apply an optimal start-up voltage to a backlight lamp according to an environment temperature, such that the backlight lamp is stably started without damage to the system. If the backlight lamp is not started in the normal condition, the start-up voltage level is gradually increased. The start-up voltage level is adjusted by controlling an amount of electric current flowing into the backlight lamp by using a plurality of parallel-connected capacitors, each having a switching element. If an abnormal electric current is detected in the backlight inverter system, an automatic shut-down function is further performed to automatically stop the system, thereby protecting the system from an overcurrent.
