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: 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.

Abstract: A stacked display panel construction (10) produces multishades of a single color, or a plurality of multiple colors (400, 500, 600). The system includes a nematic display panel (24) which, in one of its states, functions as a waveguide to rotate linearly polarized light from a colored polarizer (23), to produce noncolored light (NC1) from an output polarizer (25). In its other state, the display panel (24) twists the linearly polarized light to emit therefrom predominantly linearly polarized light for enabling the output polarizer (25) to emit colored light (R2). The method of making the construction includes adjusting the angle of rotation in the waveguide state of the panel (24), until only noncolored light (NC1) is emitted from the output polarizer (25). A display panel construction (800) includes three substantially identical nematic liquid crystal panels (824, 826, 828), associated electronic drive units (844, 845, 846) and associated polarizers (823, 825, 827, 829) for producing multiple colors.
