Abstract: In order to prevent a rapid decrease in luminance of a screen as an average picture level (APL) increases, a display device for controlling luminance of an image through a peak luminance control (PLC) curve may comprise a display unit and a controller configured to obtain a first average picture level (APL) of a first image, to determine whether a second APL of a second image is increased compared to the first APL as the first image is switched to the second image, and to control image quality of the second image to reduce an output level of the second image when the second APL is increased compared to the first APL.

Abstract: The present invention relates to an image display apparatus. The image display apparatus includes a display; a processor configured to control to supply a power to the display; and a power supply configured to convert an input AC power and output converted first DC power and second DC power to the processor and the display, wherein the power supply comprises a discharging unit configured to discharge the first DC power when a supply of the AC power to the power supply is stopped, wherein the processor is configured to supply the second DC power to the display according to a level of a voltage outputted from the discharging unit, when the supply of the AC power to the power supply is stopped and then supplied again. Accordingly, when the AC power is supplied to the power supply of the image display apparatus, the display can be quickly turned on.
