Publication number: 20180292663Abstract: A projector system comprising a laser light source, a collimating lens, a fly-eye lens, an integrating rod and a first modulator is disclosed. The light from a laser light source/fiber illuminates a collimator to substantially collimate the light and then is transmitted through a fly's-eye lens. The fly's-eye lens provides a desired angular/spatial light distribution for further processing to a first modulator of the projector system.Type: ApplicationFiled: October 11, 2016Publication date: October 11, 2018Applicant: Dolby Laboratories Licensing CorporationInventors: Martin J.

Publication number: 20180210220Abstract: Shaped glasses have curved surface lenses with spectrally complementary filters disposed thereon. The filters curved surface lenses are configured to compensate for wavelength shifts occurring due to viewing angles and other sources. Complementary images are projected for viewing through projection filters having passbands that pre-shift to compensate for subsequent wavelength shifts. At least one filter may have more than 3 primary passbands. For example, two filters include a first filter having passbands of low blue, high blue, low green, high green, and red, and a second filter having passbands of blue, green, and red. The additional passbands may be utilized to more closely match a color space and white point of a projector in which the filters are used. The shaped glasses and projection filters together may be utilized as a system for projecting and viewing 3D images.Type: ApplicationFiled: March 21, 2018Publication date: July 26, 2018Applicant: Dolby Laboratories Licensing CorporationInventors: Martin J.

Publication number: 20180210217Abstract: 3D glasses include an absorptive layer in a single lens of the glasses. The absorptive layer may be specifically tailored for spectral separation characteristics of a 3D filter portion of the lens. The absorptive layer may be combined with, and work in conjunction with, interference layers of a lens while also operating separately as an absorber. The absorptive layer may include biometric variations and/or positive runout. The absorptive layer may selectively absorb more of one color than other colors. A balancing absorber may be included in an opposite eye channel.Type: ApplicationFiled: January 23, 2018Publication date: July 26, 2018Applicant: Dolby Laboratories Licensing CorporationInventors: Barret LIPPEY, Martin J.

Publication number: 20180024429Abstract: Prism assemblies for projector display systems disclosed receive inputs from discrete color channels (e.g., red, green and blue channels. In one embodiment, “off state” light from the red, green, and blue DLP modulation may be reflected away from on-state light paths within the prism, tending to avoid uncontrolled scatter. In other embodiments, by keeping the colors separate for much of the prism path length, power levels may be significantly reduced at typical failure points. Light efficiency may be increased significantly when using discrete light sources like LEDs and lasers by removal of the additional red, green, and blue separation and re-combination losses.Type: ApplicationFiled: December 21, 2015Publication date: January 25, 2018Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Duane Scott DEWALD, Nathan WAINWRIGHT, Douglas J.

Publication number: 20170371168Abstract: Integrating rod modules are disclosed comprising a plurality of single and/or solid integrating rods that are mated together by straps. Such modules tend to comprise a greater length than the single and/or solid integrating rods and provide good illumination to a modulator that light from a light source is transmitted through the integrating rod module. The straps may comprise a material (e.g., glass) that has substantially same or similar thermal characteristics as the integrating rods. The straps may be glued to the integrating rods by a glue having a substantially different (e.g., lower) index of refraction than the integrating rods, so as not to disturb the internal reflectance of the rods. The straps may be reinforced by braces that may allow the integrating rod module to be set within a projection display system at an angle substantially different from horizontal.Type: ApplicationFiled: December 23, 2015Publication date: December 28, 2017Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Duane Scott DEWALD, Nathan WAINWRIGHT, Douglas J.

Publication number: 20170371167Abstract: Discrete light fiber inputs for high powered image projector display systems are disclosed herein. Various embodiments disclosed herein may employ a bundle of light fiber inputs, a diffuser and reducing relay optic to convert the fiber input array into a smaller pattern of spots that may be interfaced to a projector display system that may perform light recycling. Many embodiments herein may facilitate higher power laser light for illumination and, possibly, recycling. In these embodiments, laser fibers may be individually collimated and illuminate a diffuser. The diffuser spots may be then imaged through a common path relay that can be resized to allow room for the individual lasers and collimation lenses. The diffuser spots may be imaged through holes in a mirror that is on the input side of an integration rod which recycles the light.Type: ApplicationFiled: December 23, 2015Publication date: December 28, 2017Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: Duane Scott DEWALD, Nathan WAINWRIGHT, Douglas J.
