  • Publication number: 20190114977
    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: 10264225
    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: 20180358005
    Abstract: The present disclosure relates to speech recognition systems and methods that enable personalized vocal user interfaces. More specifically, the present disclosure relates to combining a self-learning speech recognition system based on semantics with a speech-to-text system optionally integrated with a natural language processing system. The combined system has the advantage of automatically and continually training the semantics-based speech recognition system and increasing recognition accuracy.

  • Patent number: 10033940
    Abstract: A camera has two distinct image sensor arrays. The image sensor arrays are at least one of different types and different resolutions. The image sensor arrays have different dynamic ranges such that one of the image sensor arrays is a high dynamic range image sensor array configured to capture a wider range of light intensity than the other of the image sensor arrays. The camera has an imaging mechanism configured to combine information collected by each of the image sensor arrays to produce a high dynamic range image. The image sensor arrays include one low resolution image sensor array having a high dynamic range, and one high resolution image sensor array having a normal dynamic range smaller than the high dynamic range wherein luminance values within the normal dynamic range represent a subset of luminance values within the high dynamic range.

  • Publication number: 20180190215
    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: 9810943
    Abstract: Parallax in an optical device is reduced by apply one or a combination of several disclosed techniques, including reduced solid angle or increased collimation of light sources, increased diffusion/scattering at an output of the device, and/or reflective structures for collimation and containment of reflected light. The techniques are advantageously applied to a backlight LCD display, and particularly to high dynamic range dual modulation displays.

  • Publication number: 20170221427
    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.
