Abstract: A disclosed display apparatus may include a display panel having a plurality of sub-pixels and configured to display an image based on an image signal provided to the display panel; a controller configured to determine a required power for at least one frame of the image signal and to output a switch signal based on determining if the required power is equal to or higher than a predetermined reference power; and a power supply device configured to receive an external AC power and to generate a first high-level voltage and a second high-level voltage. The power supply device may be further configured, based on the switch signal, to output the first high-level voltage to drive the display panel, or to combine the second high-level voltage with the first high-level voltage to generate a third high-level voltage and to output the third high-level voltage to drive the display panel.
