Patent number: 10373574Abstract: 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: February 26, 2018Date of Patent: August 6, 2019Assignee: Dolby Laboratories Licensing CorporationInventors: Lorne A. Whitehead, Gregory John Ward, Louis D. Silverstein, Helge Seetzen

Patent number: 9269309Abstract: Embodiments of the invention facilitate high-dynamic-range (HDR) imaging by generating portions of spatial and/or temporal luminance patterns with different spectral power distributions substantially concurrent with, for example, the modulation of the light intensity associated with the portions of luminance patterns. The method can include predicting luminance patterns associated with multiple spectral power distributions. The method also can include distributing portions of the luminance patterns in one or more temporal fields. In some embodiments, distributing the portions of the luminance patterns can include interlacing those portions. Further, the method can include modulating light intensities of the luminance patterns to produce an age with other spectral power distributions. In some embodiments, the distribution of the luminance pattern portions can be substantially synchronous with modulating the light intensity of the luminance patterns.Type: GrantFiled: June 29, 2010Date of Patent: February 23, 2016Assignee: Dolby Laboratories Licensing CorporationInventors: Michael Kang, Louis D.
