Patent number: 11307428Abstract: 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: GrantFiled: November 24, 2020Date of Patent: April 19, 2022Assignee: Dolby Laboratories Licensing CorporationInventors: Martin J.

Patent number: 10534251Abstract: 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: GrantFiled: December 17, 2018Date of Patent: January 14, 2020Assignee: Dolby Laboratories Licensing CorporationInventors: Duane Scott Dewald, Nathan Wainwright, Douglas J.

Patent number: 10534188Abstract: 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: GrantFiled: April 26, 2019Date of Patent: January 14, 2020Assignee: Dolby Laboratories Licensing CorporationInventors: Duane Scott Dewald, Nathan Wainwright, Douglas J.

Patent number: 10114224Abstract: 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: GrantFiled: December 23, 2015Date of Patent: October 30, 2018Assignee: Dolby Laboratories Licensing CorporationInventors: Duane Scott Dewald, Nathan Wainwright, Douglas J.
