摘要： A Liquid Crystal on Silicon (LCOS) kernel for a light engine is configured in a kernel having light paths in three dimensions (3D kernel). The 3D kernel allows for designs that do not require Wavelength Dependent Waveplates (WDWS) (or Wavelength Specific Retarders) for managing light polarizations within the 3D kernel. In one embodiment, the 3D kernel includes a Polarizing Beam Splitter (PBS) that is positioned to direct lightpaths within the 3D kernel in the 3rd dimension (e.g., light path planes perpendicular to planes of input light provided to the 3D kernel). The 3rd dimension is, for example, an output light path perpendicular to an input light plane. The 3D kernel allows for designs that incorporate reflective LCOS microdisplays and management of light paths without WDWs. The kernel is suitable for use in High Definition (HD) LCOS Rear Projection Televisions (RPTVs) and other projector applications.

摘要： Liquid Crystal on Silicon (LCoS) microdisplays are individually illuminated with primary color light beams separated from an input light. The primary colors of the input light are sequentially changed and each microdisplay “displays,” or is otherwise energized to modulate the primary color light beam illuminating the microdisplay with image content. Each microdisplay's image content is “displayed” synchronously with, and is of a color corresponding to, the primary light beam illuminating the microdisplay. The modulated primary color light beams are recombined and output to a display. The primary colors of the input light alternate, for example, between either of RGB and YMC, and RGB and YCM. The alternating primary colors are, produced, for example, by a color wheel having sections of color transmissive filters.

摘要： A variable retarder is inserted in one or more light channels of a kernel. The variable retarder is a nematic liquid crystal layer that is energized by an electric field and, for example, the voltage or frequency of the electric field dictates an amount of retardation effected by the variable retarder. The variable retarder either increases or decreases an optical path in which it is inserted relative to a reference. The amount of increase or decrease is utilized to place light paths in the kernel within acceptable tolerances. The acceptable tolerances are, for example, a tolerance of difference-light paths expected by a projection lens of device using the kernel for light modulation. In one embodiment, the variable retarder includes a polymer that can be used to fix a retardation value of the variable waveplate.

摘要： A variable retarder is inserted in a polarized light beam. The retardance of the variable retarder is increased when the light beam increases in brightness and is decreased when the light beam decreases in brightness. The amount of increase and/or decrease in retardance is calculated to stabilize the brightness of the light beam. The variable retarder may be used in conjunction with an auto-iris and share a same brightness detector.

摘要： A variable retarder and linear polarizer are placed in series in a polarized light path. A transmission axis of the linear polarizer is parallel to an axis of a polarization of the polarized light. An amount of retardation dialed into the variable retarder causes an amount of the light to have a component with an amount of off axis polarization. The off-axis components do not pass the linear polarizer, causing a reduction in the brightness of the polarized light. The combined variable retarder and linear polarizer operate as a light shutter that may be utilized, for example, to increase contrast ratio and bit depth regardless of light level in a video projection system (e.g., LCoS light engines).

摘要： Ultra Violet (UV) light produced by a light source is converted to visible light and utilized in a visible light output of the light source. The light source is, for example, a light source in an illuminator of a projection device. UV light that is typically filtered out of the illuminator is converted by a UV absorbing visible light radiating phosphor. The UV light is directed to the phosphor by, for example, reflecting the UV light out of a light path, concentrating the UV light via a concave reflector, and directing the UV light to the phosphor. The re-radiated visible light is then injected back into the light path of the light source. In one embodiment, the re-radiated visible light is injected into a “shadow” of the light path.

摘要： A transmissive LCD is placed in optical series with pixels of an image. The transmissive LCD is set to full transmissivity when bright pixels of the image pass through the transmissive LCD. Transmissivity is decreased where pixels darker than a darkening threshold pass through the transmissive LCD. A darkening curve representative of an amount of darkening performed by the transmissive LCD provides an amount of darkening to be performed on each pixel. Preferably, the darkening curve gradually darkens pixels more as the pixels themselves are darker. The darkening curve may be implemented as a formula or a look-up table in software or drive electronics that energize the transmissive LCD. Both the darkening threshold and the darkening curve may be user selectable.

摘要： A phosphor layer is positioned to absorb UV light and re-radiate usable light in other wavelengths. The UV light is reflected to the phosphor by a thin film placed in a light path. The phosphor re-radiates the usable light in a direction of the light path. Curved mirrors or directive reflectors are utilized to direct some of the re-radiated light toward the light path. In one embodiment, usable light in the light path is reflected by a thin film, UV light is passed by the thin film toward the phosphor, and the re-radiated light is directed toward the reflected visible light path.

摘要： A compensated higher order waveplate is constructed of substrates. In one embodiment, a first substrate is a nλ waveplate and the second substrate is a (n+Δ)λ waveplate. The substrates are oriented so that their principle axes of retardation are orthogonal. nλ is a base retardation of a waveplate and Δλ is an incremental retardation. The incremental retardation produces a desired amount of retardation of a lightwave passing through the compensated higher order waveplate. Retarder material used to produce the base retardation is approximately ½ a desired thickness of the waveplate. Multiple waveplates are combined to produce any of wavelength band specific retarders and multiple non contiguous wavelength band specific retarders.

摘要： An achromatic liquid-crystal shutter with high dynamic range, good transmission, and high speed. The inventive shutter reduces the phenomenon of "ghosting" (image doubling) that typically occurs in conventional plano-stereoscopic CRT displays due to the low dynamic range of surface mode liquid crystal electro-optical shutters included within such displays. The inventive shutter reduces crosstalk, thus allowing comfortable fusion to take place. In one preferred embodiment, the inventive shutter system is driven by a carrier-less voltage signal having time-averaged voltage substantially equal to zero, so that a simple, low power driving circuit suffices to drive the shutter. A pair of the inventive achromatic shutters may be employed in a wireless mode as a selection device for a field-sequential stereoscopic electronic display system.
