  • Patent number: 5546687
    Abstract: A transparent acrylic sheet carries a mirrored coating on its back surface. The sheet has a ground front surface that has a layer of fluorescent paint, or, alternatively, a translucent layer of diluted fluorescent paint applied thereto. The fluorescent paint layer carries a cibachrome image transparency. Light passes through an edge of the sheet to the ground surface where it is diffused and amplified by the excitation of the fluorescent particles in the fluorescent paint. The amplified, diffused light illuminates a back surface of the transparency, thereby providing a display of an illuminated image to an observer who views a front surface of the transparency.
