Abstract: Dual modulator displays are disclosed incorporating a phosphorescent plate interposed in the optical path between a light source modulation layer and a display modulation layer. Spatially modulated light output from the light source modulation layer impinges on the phosphorescent plate and excites corresponding regions of the phosphorescent plate which in turn emit light having different spectral characteristics than the light output from the light source modulation layer. Light emitted from the phosphorescent plate is received and further modulated by the display modulation layer to provide the ultimate display output.

Abstract: A method for estimating an effective luminance pattern representing a distribution of projected light in a display apparatus involves determining driving values for one or more light sources arranged to project light. The light sources are solid-state light sources such as light-emitting diodes in some embodiments. The method determines an effective luminance pattern for the projected light by determining contributions to the effective luminance pattern for different components of a point spread function and then combining the contributions of the components the effective luminance pattern to yield an estimated effective luminance pattern.

Abstract: A display has a screen which incorporates a light modulator. The screen may be a front projection screen or a rear-projection screen. The screen is illuminated with light from a light source comprising an array of controllable light-emitters. The controllable-emitters and elements of the light modulator may be controlled to adjust the intensity of light emanating from corresponding areas on the screen. The display may provide a high dynamic range.

Abstract: Apparatus and methods are provided that employ one or more of a variety of techniques for reducing the time required to display high resolution images on a high dynamic range display having a light source layer and a display layer. In one technique, the image resolution is reduced, an effective luminance pattern is determined for the reduced resolution image, and the resolution of the effective luminance pattern is then increased to the resolution of the display layer. In another technique, the light source layer's point spread function is decomposed into a plurality of components, and an effective luminance pattern is determined for each component. The effective luminance patterns are then combined to produce a total effective luminance pattern. Additional image display time reduction techniques are provided.
