Patent ID: 8654142

Claim:
A color accurate display device 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, comprising: 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 native primaries having a second gamut larger than and including the first gamut; and a color space conversion circuit configured to: linearize any gamma encoded primaries in a shadow region of the first color space to the shadow region of the second color space, subsequent to linearizing the gamma encoded primaries in the shadow region, 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, and linearize the converted native primaries in the shadow region to compensate for any subsequent gamma encoding of the native primaries by the display panel, wherein the color space conversion circuit converts the encoded primaries from a first bit resolution in the first color space to a second bit resolution in the second color space, the second bit resolution being greater than the first bit resolution.
