Abstract
A table-top rear projection television employs a single large-panel (e.g., 7 inch-15 inch, 17.5 cm-38 cm, diagonal), multi-color transmissive imaging device (e.g., an amorphous silicon liquid crystal display). The rear projection television has a cabinet with a pedestal having a height and a depth that are each less than or equal to about 0.65 the height of the display screen. The display screen may have any aspect ratio of a wide format (e.g., 16:9, 15:9, 16:10) or a conventional format (i.e. 4:3).
