摘要： A pathlength matched prism assembly is constructed from Polarizing Beam Splitter optical components having varying degrees of precision by arranging them in pathlength matched positions and fixing them to a baseplate or frame. Gaps between the optical components are sealed by the frame or adhesive sealant. Planar optical elements are inserted between the optical components and space between the components and elements is filled with an optical coupling fluid having an index of refraction that closely matches the index of refraction of both components and elements. An expansion compensation device is attached to the prism assembly to compensate of expansion and contraction of the optical coupling fluid. The prism assembly is best suited for use in HDTV and High Definition video projectors.

摘要： Kernels are designed in different configurations based on design properties of an enclosure or other requirements. A prism assembly having various types of filters, waveplates, beam splitters (e.g., path length matched beam splitters) and/or other optical components are provided to selectively direct light beams to each of red, green, and blue microdisplays that manipulate the light and then combine the manipulated lights into an output image. The prism assembly includes an input face, an output face, and other faces on which the microdisplays are attached in a number of different configurations. Requirements and exact placement of optical components varies depending on which microdisplay is attached to which face. The components of the prism assembly may be arranged in path length matched positions.

摘要： A lens includes mechanical dithering that displaces pixels adjacent to undithered pixels. The dithering, for example, precisely places pixels above, below, and on both sides of the undithered pixel. Image data is supplemented with interpolation and/or new data in additional pixel locations. The image data may be projected by a dithered lens.

摘要： An optical element is disposed between cover glasses, and an optical coupling liquid is injected between the optical element and the cover glasses to form an optical package. An adhesive provides a liquid tight seal between the cover glasses. The optical element is a retarder, filter, polarizing film, or other optical element. Spacers are placed between the optical element and cover glasses to maintain space between the optical element and the cover glasses and assist in distribution of the optical coupling liquid. Applications include prism assemblies and other optical products. The invention may also be applied to joining optical components with liquid joints. For example, an optical switch includes a controllable retarder in a liquid filled joint.

摘要： A device package has a bezel attached to a carrier. The bezel extends toward a surface of an optical component to which a device mounted in the carrier is attached. The bezel extends in a direction and to a distance that allows the bezel to act as a guide for a dislodging tool. The dislodging tool is guided to an interface where an adhesive attaches the device to the optical component. Preferably, the device is a microdisplay attached to a prism assembly. The bezel may also be used to attach the device package to the optical component with either an air gap or a liquid coupling the microdisplay (and/or an optical stack) and the optical component. An air bladder, air bubble, or tube device is included in the liquid coupling to accommodate expansion of the liquid.

摘要： Images to be displayed are produced for left-eye viewing and right-eye viewing in synchronization with a polarization device that alternately changes polarization of the viewed images. In one embodiment, a control mechanism synchronizes modulation performed by microdisplays in a reflective Liquid Crystal On Silicon (LCOS) kernel with an electronically controlled shutter that alternately converts light output from the LCOS kernel between S and P polarizations. Prior to reaching the shutter (or other polarization switching device) a wavelength specific retarder is utilized so that the polarizations of various light channels are homogenous. The kernel installed in, for example, a 3-D enabled monitor, 3-D gaming device, or a 3-D enabled High Definition (HD) LCOS Rear projection television (RPTV). In one embodiment, the LCOS Kernel is an LMS™ LiquidVision™ or LMS AT™ kernel

摘要： An absorptive layer is added to an image display system. The absorptive layer is selected to compensate for tint in a black state of a displayed image. In a Liquid Crystal On Silicon (LCOS) based light engine, blue wavelengths may cause a predominate tint in black portions of an image (or an entirely black image is tinted blue), and the absorptive layer is calculated to absorb an amount of blue equivalent to the tint. The absorptive layer is, for example, an unbalanced magenta dichroic, or a yellow filter. The yellow filter may be placed at any point in the light chain, including input/output of a kernel, input/output of a projection lens, or portions of a light engine or display screen. An unbalanced magenta may be constructed by adding a yellow filter to an existing magenta dichroic in the kernel design.

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： A hollow sphere with a scattering (e.g., white diffusive) interior surface directs light input from at least one input light source to an exit. In one embodiment, an internal hot mirror and phosphor are positioned to intercept the input light on which visible light is reflected and ultraviolet light is directed to the phosphor for conversion to visible light. The exit has a reflective polarizer that passes light of a selected polarization to an output. Light of other polarization(s) is reflected back into the sphere where it becomes unpolarized because of reflections and may eventually be returned to the exit at the selected polarization.
