Abstract: A display for displaying image data includes defining virtual color gamuts based on a plurality of primary display colors associated with a light source. At least one of the virtual color gamuts is defined to approximate an established color gamut. Intensity values associated with the virtual color gamuts are generated based on received video data, and the intensity values associated with the virtual color gamuts are used to generate drive values for the primary colors of the light source. A display using one or more virtual color gamuts is also disclosed.

Abstract: Light projection systems using white light illumination. One embodiment provides a projection system using white light illumination. The projection system includes an illumination assembly configured to receive a white light input. A prism is configured to separate the white light input into color light inputs, redirect the color light inputs to respective modulators, and combine modulated color light inputs from the respective modulators into a white light output. An optical filter is configured to spatially Fourier transform the white light output to generate a filtered white light output. A projection lens assembly is configured to project the filtered white light output.

Abstract: A projection system and method therefore related to a first projection device; a second projection device; at least one spatial modulator; and an electronic processor configured to: receive a two-dimensional video data, generate a first plurality of intensity values of a first color gamut and a second plurality of intensity values of a second color gamut, subtract a luminance threshold from a plurality of pixel values of the second color gamut to yield a plurality of positive pixel values and a plurality of negative pixel values, set respective ones of the plurality of pixel values to predetermined values to obtain a residual of the second color gamut, add the residual to the first color gamut, add maximized pixel values to the first color gamut and the second color gamut to create an output gamut, and blend the output gamut with a native color gamut to generate a blended gamut.

Abstract: A novel projection system includes a light source, a phase modulator, an amplitude modulator, and a controller having temporal lightfield simulation capabilities. The phase modulator spatially modulates a lightfield from the light source to generate an intermediate image on the amplitude modulator. The amplitude modulator spatially modulates the intermediate image to form a final image. The controller models the phase state of the phase modulator during transitions between phase modulator frames and generates lightfield simulations of the intermediate image during the transition. The controller utilizes the lightfield simulations to generate and provide sets of amplitude drive values to the amplitude modulator at a faster rate than that at which the phase modulator is capable of switching.
