Disclosed is a video display system comprising a spatial light modulator, such as a DMD modulator. The system uses a light source and color-wheel filter that is interposed between the light source and the spatial light modulator, the color-wheel filter being divided into primary color segments and at least one neutral density (“ND”) segment that is complementary to at least one of the primary color segments and having a transmissivity that is lower than that of its corresponding primary color segment. At the border between the ND segment and its complementary primary color segment is an area that can be referred to as an ND spoke. The video display system modulates light from this ND spoke area along with light from the other segments.
A video display system, comprising:
A method of display an image using a spatial light modulator, such that said spatial light modulator creates images by deflection of selected ones of an array of individual pixels over a period of time, wherein the period is divided into intervals, the method comprising:
