Abstract:
1. A method of displaying an image, the method comprising: converting a source image signal into an image signal corresponding to a color space for a color gamut mapping; adjusting a color gamut of the image signal based on a color production mode, wherein the adjusted color gamut of the image signal is substantially identical to a display color gamut when the color production mode is a low luminance color production mode, and the adjusted color gamut of the image signal is smaller than the display color gamut when the color production mode is a high luminance color production mode; mapping the image signal corresponding to colors within the adjusted color gamut into an image signal corresponding to colors within the display color gamut, wherein the colors of the display color gamut are displayed by a display panel; driving the display panel using the mapped image signal; and generating light to provide the display panel with the light, wherein when the color production mode is the high luminance color production mode, the color gamut of the image signal is reduced using a white coefficient and a luminance of the light is increased using a boosting coefficient which is a reciprocal of the white coefficient.
