Claim 13:
14. A method for compensating colors of a display, the display comprising an array of pixels, wherein pixels in the array comprise a plurality of first sub-pixels defining a first color area in a chromaticity plane, a plurality of second sub-pixels defining a second color area in the chromaticity plane, and a plurality of third sub-pixels defining a third color area in the chromaticity plane, and wherein the plurality of first sub-pixels is associated with a first primary color, the plurality of second sub-pixels is associated with a second primary color, and the plurality of third sub-pixels is associated with a third primary color, the method comprising:
determining a first chromaticity coordinate point of the first color area, a second chromaticity coordinate point of the second color area, and a third chromaticity coordinate point of the third color area;
determining a compensation matrix for generating a control signal based on an input image signal, wherein the control signal controls each pixel of the display to emit light in a virtual color gamut,
wherein the virtual color gamut includes a first virtual color gamut including the first chromaticity coordinate point, a second virtual color gamut including the second chromaticity coordinate point, a third virtual color gamut including the third chromaticity coordinate point, and a fourth virtual color gamut,
wherein the fourth virtual color gamut is defined based on the first color area, the second color area, and the third color area, and the fourth virtual color gamut is among the first, second and third color areas on the chromaticity plane and does not overlap any of the first, second or third color areas; and
determining at least a first luminance adjustment parameter, such that light on the first chromaticity coordinate point is emitted when a pixel is controlled to emit light of the first primary color.
