Abstract
A color accurate display device is configured to receive an encoded first color space having a first gamut from a set of encoded primaries {R, G, B} and a first white point. The device includes a display panel having an active area configured for an encoded second color space having a second white point and a set of native primaries each with a characterized tone response with respect to the second color space and a measured tone response from the display panel, the primaries having a second gamut larger than and including the first gamut. Also included is a color space conversion circuit configured to convert the set of encoded primaries {R, G, B} and first white point of the first color space to the set of native primaries and second white point compensating for each characterized tone response of the second color space.
