Abstract: The present invention provides a cinema screen that improves audience perception of brightness at, for example, a premium theater without additional illumination cost. The screen is produced from materials that also help mitigate speckle from laser illumination. The screen has properties and includes structures that may be tuned to the specific capabilities of the projection system, arrangement of the theater, and projector (and angle of projection, angle of viewing). Light reflected from the screen are direct toward audience members and away from walls and ceilings.

Abstract: Projector display systems comprising a light dimmer and first modulator are disclosed. The light dimmer may comprise an adjustable iris, adjustable light sources and/or LCD stack that is capable of lowering the luminance of the light source illuminated the first modulator. The first modulator may comprise a plurality of analog mirrors (e.g. MEMS array) and the second modulator may comprise a plurality of mirrors (e.g., DMD array). The display system may further comprise a controller that sends control signals to the light dimmer and first modulator. The display system may render a desired dynamic range for rendering a projected image by a combination of such control signals.

Abstract: 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.

Abstract: 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.

Abstract: Dual or multi-modulation display systems are disclosed that comprise projector systems with at least one modulator that may employ non-mechanical beam steering modulation. Many embodiments disclosed herein employ a non-mechanical beam steering and/or polarizer to provide for a highlights modulator.

Abstract: 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.

Abstract: Projection systems and/or methods for efficient use of light by recycling a portion of the light energy are disclosed. In one embodiment, a projection display system is disclosed comprising a light source; an integrated rod that receives light from said light source at a proximal end that comprise a reflective surface which may reflecting/recycle light down said integrating rod; and a modulator comprising at least one moveable mirror that reflects light received from the integrating rod in either a projection direction or a light recycling direction. In other embodiments, dual and multiple modulator projector display systems are disclosed. A first modulator may affect either a pre-modulated halftone image or may affect a highlights modulated image for a desired image to be displayed. A second modulator may be provided for primary modulation of a desired image.
