    Abstract: Disclosed are embodiments of photo-luminescent display systems and photo-luminescent visual elements creating eye-catching displays of visual advertising or marketing messages that are very effective at generating interest, engagement, and loyalty in the viewing public. Photo-luminescent pigment containing visual elements are illuminated by one or more remotely located emitters at a first wavelength that is outside the human visual spectrum. In response, the visual elements then radiate at one or more wavelengths within the human visual spectrum. Additional features control unwanted reflections and unwanted transmission of radiation at the first wavelength. Additional features control the uniformity of radiation of one or more wavelengths within the human visual spectrum.

  • Patent number: 8809811
    Abstract: Embodiments of fluorescent display screens having an intermediate layer between a light-emitting fluorescent layer and an excitation filter layer are disclosed. The intermediate layer includes (1) a low-index layer disposed between the light-emitting fluorescent layer and the excitation filter layer and (2) an index bridging layer disposed between the low-index layer and the excitation filter layer. The insertion of the low-index layer and the index bridging layer according to the above configuration reduces the sensitivity of the excitation coupling to the non-uniformities in the excitation filter layer and variability in the output frequency of the excitation source, leading to improved uniformity of display intensity without significant compromise in the excitation coupling efficiency. A index bridging region made of a hard coat also provides abrasion resistance and provides structure rigidity to the adjacent excitation filter layer.
