Abstract
By selectively placing color filters with different transmittance spectrums on an array of modulator elements each having the same reflectance spectrum, a resultant reflectance spectrum for each modulator element and it'"'"'s respective color filter is created. In one embodiment, the modulator elements in an array are manufactured by the same process so that each modulator element has a reflectance spectrum that includes multiple reflectivity lines. Color filters corresponding to multiple colors, such as red, green, and blue, for example, may be selectively associated with these modulator elements in order to filter out a desired wavelength range for each modulator element and provide a multiple color array. Because the modulator elements are manufactured by the same process, each of the modulator elements is substantially the same and common voltage levels may be used to activate and deactivate selected modulation.

46. A display comprising:
-
a spatial light modulator having a dark state and a light state, wherein the dark state has an emission spectrum that includes visible light near at least one end of the visible spectrum such that the dark state produces a non-black color; and a filter structure disposed so as to receive light output by the spatial light modulator, wherein the filter structure is configured to attenuate visible light near the at least one end of the visible spectrum so as to darken the dark state of the spatial light modulator. - View Dependent Claims (47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68)

69. A method of forming an image, the method comprising:
-
providing a plurality of spatial light modulators, wherein each of the plurality of spatial light modulators has a light state and a dark state; setting a first group of the spatial light modulators to the light state; setting a second group of the spatial light modulators to the dark state; outputting light from the plurality of spatial light modulators, wherein the light outputted by the second group of spatial light modulators set to the dark state includes light near at least one end of the visible spectrum such that the dark states of the second group of spatial light modulators produces a non-black color; and attenuating the visible light near the at least one end of the visible spectrum that is outputted by the spatial light modulators so as to darken the dark state of the second group of spatial light modulators. - View Dependent Claims (70)
