Abstract: A display apparatus is provided. The display apparatus includes a display panel including a plurality of pixels and configured to display an image corresponding to an image signal, a backlight including a plurality of light sources, and configured to independently operate a light emitting block corresponding to each of the plurality of light sources to provide light to the display panel, and a processor configured to control an amount of light of each of the plurality of light sources according to the image signal. The processor is configured to calculate an amount of a red (R) light, an amount of a green (G) light, and an amount of a blue (B) light that at least one light source among the plurality of light sources is configured to emit to one area on the display panel, identify the color information of the one area based on each of the calculated amounts of the R light, the G light, and the B light, and adjust an image signal corresponding to the one area based on the identified color information.
