Abstract
A display apparatus includes a display panel in which a plurality of pixel units are disposed, a backlight providing light to the display panel, and a data processing circuit receiving image signals and providing the image signals to the plurality of pixel units. The data processing circuit sets a luminance level of the backlight to a value corresponding to a color gamut boundary of the image signals adjacent to a saturation region.
