摘要： 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.

摘要： 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.

摘要： A dual-modulation projection system (100) includes a light source (102), a phase modulator (104), an amplitude modulator (106), and a controller (110) having temporal lightfield simulation capabilities (114). The phase modulator (104) spatially modulates a lightfield from the light source (102) to generate an intermediate image on the amplitude modulator (106). The amplitude modulator (106) spatially modulates the intermediate image to form a final image. The controller (110) models the phase state of the phase modulator (104) during transitions between phase modulator frames and generates lightfield simulations of the intermediate image during the transition. The controller (110) utilizes the lightfield simulations to generate and provide sets of amplitude drive values to the amplitude modulator (106) at a faster rate than that at which the phase modulator (104) is capable of switching.

摘要： A display incorporates both narrow-band light emitters and broadband light emitters. The light emitters are controlled to display images according to image data. The narrow-band light emitters can be used to provide highly saturated primary colors. Light from the broadband light sources may be mixed with the broadband light. This can reduce metamerism failures arising from variations in the characteristics of the eyes of observers.
