Claim Text:
1. A display comprising a backlight having a plurality of differently colored light sources, the backlight being coupled to a spatial light modulator, a display element part having addressable pixels of the spatial light modulator for dynamically controlling a luminance of each of said addressable pixels according to an input signal, the input signal comprising the information corresponding to an image to be displayed by the addressable pixels of the display, the spatial light modulator having a non-uniform spatial optical characteristic dependent upon video level, an optical and electronic correction part having an optical filter having a non-uniform spatial pattern to alter the luminance and/or color to compensate at least partially for the non-uniform spatial optical characteristic of the spatial light modulator and an electronic signal processing element arranged to apply some pre-compensation for the non-uniform spatial optical characteristic of the spatial light modulator to the input signal, wherein the optical filter is arranged downstream of the spatial light modulator.
