Abstract

An inverter apparatus for driving a plurality of lamp units including a plurality of lamps is provided. The inverter apparatus includes a plurality of inverters. Each inverter includes a delay block delaying an input ON/OFF signal to generate an output ON/OFF signal and an inverting block controlling the lighting of the corresponding lamp unit based on the output ON/OFF signal. The plurality of inverters includes a first inverter receiving the input ON/OFF signal from an external device and a second inverter receiving the input ON/OFF signal from one of the plurality of inverters.

Claims (7)

1. A backlight unit comprising:

a plurality of lamps;

a plurality of inverters controlling the lighting of at least one of the lamps;

a delay circuit as a driving signal generator receiving an input signal and generating at least two output signals for driving the inverters, the output signals each having a different phase from each other,

wherein the delay circuit comprises a plurality of RC circuits connected in series and one of the RC circuits receives the input signal.

2. The backlight unit of claim 1 , wherein the delay circuit comprises a plurality of input resistors connected to the respective RC circuits.

3. The backlight unit of claim 2 , wherein the RC circuits are connected to the respective inverters.
