Patent ID: 8531125

Claim:
A display apparatus, comprising: a liquid crystal display (LCD) panel which displays an image thereon; and a backlight assembly which emits light to the LCD panel, wherein the backlight assembly comprises: a power unit which outputs a current whose polarity is changed on a regular basis; a plurality of balancing units which is connected in parallel to the power unit; a plurality of LED modules which individually receives each current output by one of the plurality of balancing units; and a driver which is connected between the plurality of balancing units and the plurality of LED modules, and forms a current route for each balancing unit to balance a current supplied to two different LED modules during a single period where the polarity of the current output by the power unit is changed, wherein each of the plurality of light emitting diode (LED) modules comprises a plurality of LEDs, and wherein the driver comprises: a first diode line which forms a first current route supplying a current output by a first end of the transformer to a first LED module if the current output by the power unit is positive; and a second diode line which forms a second current route supplying a current output by a second end of the transformer to a second LED module if the current output by the power unit is negative.
