Publication number: 20180182310Abstract: 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.Type: ApplicationFiled: February 20, 2018Publication date: June 28, 2018Applicant: Dolby Laboratories Licensing CorporationInventors: Lorne A. Whitehead, Helge Seetzen, Gregory John Ward, Wolfgang Heidrich

Patent number: 9911389Abstract: 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.Type: GrantFiled: October 19, 2016Date of Patent: March 6, 2018Assignee: Dolby Laboratories Licensing CorporationInventors: Lorne A.

Patent number: 9810943Abstract: 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.Type: GrantFiled: September 16, 2013Date of Patent: November 7, 2017Assignee: Dolby Laboratories Licensing CorporationInventors: Lorne A.

Publication number: 20170221427Abstract: 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.Type: ApplicationFiled: April 21, 2017Publication date: August 3, 2017Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventor: Helge SEETZEN
