Zusammenfassung:	A display apparatus is provided, the display apparatus includes a display panel, a backlight unit comprising a light source which irradiates a light to the display panel, a storage which stores a gamma curve indicating relationship between a gray level of an input signal and a luminance of an output signal, and a processor configured to control the backlight unit to decrease a brightness of the light provided to the display panel based on a difference between a first output luminance value which is a maximum luminance value of the display panel and a second output luminance value of the input signal, in which the second output luminance value may be an output luminance value corresponding to the maximum gray level value of the input signal in the gamma curve.
