ABSTRACT:
A display apparatus is provided having an LCD panel and a backlight unit to illuminate the LCD panel, and further including a temperature sensor to sense the temperature of the backlight unit, an inverter to drive the backlight unit, a power supply to supply power to the inverter, and a controller to control the power supply to supply an initial voltage that is higher than a normal voltage when the power is initially supplied, and gradually lower the voltage applied to the inverter to return to a substantially normal voltage in the case where the temperature of the backlight unit is higher than a predetermined normal temperature or when a time period has passed. Thus, the display apparatus and control method thereof reduce the time taken to stabilize brightness when initially driving a display apparatus, and display a stable and high-quality picture.
