Patent ID: 8384733

Claim:
A display device, comprising: a liquid crystal display (LCD) panel having a plurality of pixels each having a plurality of subpixels, the LCD panel further having a native transfer function to transform a plurality of adjusted input values and output a plurality of gamma corrected input values and a native light output function to transform the gamma corrected input values into a plurality of light output levels; a liquid crystal display (LCD) backlight, the LCD backlight having a plurality of red light emitting diodes (LEDs), a plurality of blue LEDs, and a plurality of green LEDs; and a color gamut mapping engine to adjust a plurality of input values and output the plurality of adjusted input values such that the transformation of the adjusted input values to the light output levels complies with a specified output device specification in which the color gamut mapping engine further comprises: a device compensation block to adjust a standardized gamma corrected input value associated with each of the input values and output the adjusted input values; in which the device compensation block further comprises: at least one matrix multiplier to multiply the standardized gamma corrected input value associated with each of the input values by a transformation matrix and output a plurality of multiplied input values; and an inverse native transfer function to apply an inverse of the native transfer function to the multiplied input values and output the adjusted input values; in which the transformation matrix is a combination of an inverse of the native light output function and a light output function corresponding to the specified output device specification.
