Abstract: A multimedia projector (30) includes a light source (32) producing a nonuniform illumination pattern and a light integrating tunnel (110, 130) having parallelogram-shaped input and output apertures (132, 134) with an average diagonal dimension. The input and output apertures are spaced apart by a length dimension (136) that is less than five-times the average diagonal dimension of the apertures. A light pattern (150) propagating from the output aperture is substantially more uniform than a light pattern (146) propagating from a rectangular tunnel of the same length. Alternatively, a light pattern (164) propagating from the output aperture has substantially the same uniformity as the light pattern (146) propagating from a substantially longer rectangular tunnel.

Abstract: A frame assembly is provided. The frame assembly may include an inner frame disposed in a dimensionally stable relationship with a display screen where the relationship is substantially maintained during an environmental change which produces a variation in a size of the display screen. The frame assembly further includes an outer frame configured to capture the inner frame and accommodate size changes of the inner frame.
