    Abstract: A method of making a LCD panel system including selecting a pair of substrate panels, forming a peripheral seal on one of the flat surfaces of one of the panels to define an area on the panel surface, distributing compressible optical spheres over the area, aligning one substrate panel with the first and placing the second panel against the seal, in an aligned condition with the other to form a chamber. The panels are pressed together to form a fluid tight seal between the panels. Air is then evacuated from the chamber and an optical fluid is introduced into the chamber.

    Abstract: A low profile liquid crystal projector unit (10) and a method of using it to project an image with substantially no keystoning effects. An optics arrangement directs high intensity light within a housing along a path through a liquid crystal display panel (12) at an angle offset from a normal axis of the panel. The liquid crystal panel is inclined within the housing and an output mirror (24) mounted above the housing is inclined angularly opposite to the liquid crystal panel and cooperates with a lens set (71-75) for projecting the image onto a remote surface (60). The output mirror is mounted to reflect the image at an angle to the normal of the remote surface substantially equal to the angle the light path is offset from the normal of the panel.

    Abstract: The present invention relates to a compact display projector and a method of using it to project images under the control of image generating equipment, such as computers and television systems. An optical input device (10) is built into the projector (12) to enable optical control signals directed onto the projected image, to be discriminated for causing the image generating equipment to modify the projected image. A positionally adjusted mirror device (40) is disposed in optical alignment with the optical input device to reflect the optical control signals back thereto, whereby the optical input device is readily aligned with the projected image to monitor it for the occurrence of any optical control signals.

    Abstract: A high speed color display system (10) including a modulation circuit (11) electrically coupled between a high speed display device (16), such as an active matrix liquid crystal display panel, and a video output signal source (26, 14A) such as a video output card of a personal computer. The modulation circuit (11) including both a scaling circuit (35A) for eliminating or substantially reducing contouring caused by quantizing errors associated with approximations of digital pictures and a duty cycle scaling circuit (42A) for eliminating or substantially reducing repetitive beats in a displayed image. The display panel (16) is adapted for positioning on a conventional photographic projector for displaying large video images. Such a system (10) is modular and employs relatively inexpensive subassembly units such as a user selected television signal generating type device, such as a video cassette recorder (20), and a high speed display device, such as an active matrix display panel (16) adapted for positioning on a projector.

    Abstract: The display system (10) includes a liquid crystal display panel unit (12) having three different color components for each pixel of the resulting display. Each one of the individual color components of a pixel of the liquid crystal display panel unit (12) is activated selectively by a corresponding one of a set of video processing units (20, 21, 22). Each video processing unit (20, 21, 22) is responsive to a video signal from a conventional computer processor (11) for causing the reproduction of a component of a colored image. Each video processing unit (20, 21, 22) includes a translating arrangement (23, 24, 25) for converting a component part of the computer generated video signal into a binary digital signal indicative of a single one of the color components for mixing with other color components to reproduce faithfully the computer generated color image.

    Abstract: An image projection system includes a source of polarized light and a spatial light modulator, having an alignment layer, wherein the polarized light is aligned with the alignment layer to allow the light to pass without the need for polarizers. Three different colored images may be produced by three separate polarized light sources (222A, 226A, 230A) with corresponding light valve super-imposed. Light sources may either be maintained activated or may be sequenced at high input energies for short intervals to reduce average energy costs. A microlaser array (922) may be coupled with a beam shaper (936) to further increase brightness of the image. The beam shaper may include a binary phase plate to modify the shape and intensity profile of the projection light beam.
