  • Patent number: 6462868
    Abstract: A display device is provided which permits viewing of both hardcopy and digital images. An embodiment of an image viewing station comprises a housing having an internal light source and a light transmissive display panel coupled to the housing such that light from the internal light source passes therethrough. Hardcopy images affixed to an outer surface of the display panel may be transilluminated by the light passing through the display panel. Digital images may also be displayed on the display panel, by projecting the digital images onto either the inner or outer surface of the display panel. Alternatively, the panel could include a light emitting or light transmissive display panel, such as a liquid crystal display or an electroluminescent panel. Light emitted by the display panel may be sufficient to transilluminate a hardcopy image disposed on an outer surface of the display panel.
