E Earle Thompson, Thomas W DeMond: Reduced-speckle display system. Texas Instruments Incorporated, Julie L Reed, James C Kesterson, Richard L Donaldson, December 21, 1993: US05272473 (292 worldwide citation)

A digitized video system with an increased viewing angle having a light projector and a display screen. The light projector generating a plurality of narrow light beams to impinge on the display screen at a plurality of associated points. The display screen has a transducer generating surface acoust ...

Gary D Sharp, Kevin Curtis, David A Coleman: High elastic modulus projection screen substrates. RealD, Penny L Lowry, Neil G Mothew, July 18, 2017: US09709883 (1 worldwide citation)

A stiffening strip at selected edges of a screen may enable the use and mounting of a high-elastic modulus substrate screen material. Such screen materials may be engineered to provide polarization-preserving characteristics, and be applied to or part of the high-elastic modulus substrate. Furthermo ...

Douglas J McKnight, Kevin Curtis: System and method for vibrating screens to reduce speckle. RealD, Penny L Lowry, Neil G Mothew, February 20, 2018: US09897819

The present disclosure includes systems and methods for solving speckle problems by exciting the screen with a more complex vibration spectrum. A range of frequencies provides, in effect, a collection of overlapping patterns of high and low displacement, so that all regions of the screen have enough ...

Despeckling System for Projected Light. December 28, 2017: US20170371173-A1

Speckle artifacts as viewed in images projected on a display surface by a projector can be reduced. At least one spatial light modulator, illuminated by one or more light sources, can be imaged to a screen by a projection lens. A deflector subsystem can be provided in image space, proximate to the l ...
