Abstract: A display apparatus includes a light source generating blue light. A display panel is configured to display an image. A light guide member is disposed below the display panel. A first light conversion layer is disposed between the light guide member and the display panel. The first light conversion layer includes a plurality of quantum dots. A low refractive layer is disposed between the light guide member and the first light conversion layer. The low refractive layer has a refractive index that is less than that of the light guide member. A second light conversion layer is disposed between the light source and the first light conversion layer and includes a plurality of fluoride-based or nitride-based phosphors. The first light conversion layer is configured to convert the blue light into green light, and the second light conversion layer is configured to convert the blue light into red light.

Abstract: A display device includes: a display panel including a pixel including: a red sub-pixel to display a red color; a green sub-pixel to display a green color; and a blue sub-pixel to display a blue color; and a deterioration compensator to compensate for a deterioration of the pixel, and including: a luminance compensator to generate a luminance compensation value of a full color based on an input luminance of the full color; and a color coordinate compensator to: calculate display color coordinates of the red color; display color coordinates of the green color; display color coordinates of the blue color; and a ratio of the luminance compensation value of the full color based on the display color coordinates of the red color, the display color coordinates of the green color, the display color coordinates of the blue color, and input color coordinates of the full color.
