Patent ID: 8466856

Claim:
A method for displaying an image on a color display, comprising: a) providing the color display having a selected target display white point luminance and chromaticity, the color display including three gamut-defining emitters defining a display gamut and two or more additional emitters which emit light at respective different chromaticity coordinates within the display gamut, wherein each emitter has a corresponding peak luminance and chromaticity coordinate, the gamut-defining emitters produce a gamut-defining peak luminance at the target display white point chromaticity, and the gamut-defining peak luminance is less than the display white point luminance; b) receiving a three-component input image signal corresponding to a chromaticity within a supplemental gamut defined by a combination of three emitters that includes at least one of the additional emitters; c) transforming the three-component input image signal to a five-component drive signal such that when the transformed image signal is reproduced on the display, its reproduced luminance value is higher than the reproduced luminance value of a display with only gamut-defining emitters; and d) providing the five-component drive signal to respective gamut-defining and additional emitters to display an image corresponding to the input image signal.
