  • Patent number: 9478182
    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.

  • Patent number: 9478176
    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.

  • Patent number: 9462240
    Abstract: A backlight for a display comprises a plurality of independently controllable light sources and inclined surfaces inclining in a radially outward direction from each light source for shaping the distribution of emitted light. The light sources may each comprise a group of differently-colored light emitters. The backlight may include light integrators configured to mix light of the differently-colored light emitters. Inclined surfaces for shaping the distribution of emitted light may be arranged around exits of the light integrators.

  • Publication number: 20160170236
    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.

  • Publication number: 20160125818
    Abstract: A color display has a monochrome modulator. An active area of the modulator is illuminated by an array of light sources. The light sources include light sources of three or more colors. The intensities of the light sources may be adjusted to project desired luminance patterns on an active area of the modulator. In a fast field sequential method different colors are projected sequentially. The modulator is set to modulate the projected luminance patterns to display a desired image. In a slow field sequential method, colors are projected simultaneously and the modulator is set to modulate most important colors in the image.

  • Patent number: 9324253
    Abstract: Modular displays are made up of arrays of modules that include light sources and light modulators. The modules may include control circuits that perform some image processing functions. The modules may illuminate a screen directly or may include optical systems that project light onto a screen.

  • Patent number: 9269312
    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.

  • Patent number: 8948537
    Abstract: Methods and apparatus according to various aspects take as input image data in a lower-dynamic-range (LDR) format and produce as output enhanced image data having a dynamic range greater than that of the input image data (i.e. higher-dynamic range (HDR) image data). In some embodiments, the methods are applied to video data and are performed in real-time (i.e. processing of video frames to enhance the dynamic range of the video frames is completed at least on average at the frame rate of the video signal).
