Abstract: A display apparatus is disclosed. The display apparatus includes a backlight configured to emit light; a first polarizing plate, disposed in front of the backlight, configured to polarize light emitted from the backlight in a first direction; and a plurality of display panels sequentially disposed in front of the first polarizing plate, wherein each of the plurality of display panels is configured to include a liquid crystal panel and a color filter disposed in front of the liquid crystal panel, and wherein a display panel disposed at a farthest distance from the first polarizing plate from among the plurality of display panels is configured to include a second polarizing plate that polarizes the light of the first direction in a second direction.

Abstract: A method of controlling an element of a display device is provided. At least one processor of the display device may be configured to determine a first chromaticity value corresponding to a first grayscale value of the element of the display device, and determine a first luminance value corresponding to the first chromaticity value, based on the first chromaticity value and a target with respect to a relationship between chromaticity and luminance. In addition, the at least one processor of the display device may be configured to determine a second grayscale value corresponding to the first luminance value, determine a second chromaticity value corresponding to the second grayscale value, determine a second luminance value corresponding to the second chromaticity value, based on the second chromaticity value and the target, and determine chromaticity and luminance calibration coefficients, based on the second luminance value.
