Definitions

  • This invention relates to optical displays of the kind intended primarily to be viewed by rear illumination.
  • the image to be viewed is, for example, an enlarged trans ⁇ parency of a photographic print or transparency illus ⁇ trating the original subject.
  • Attempts have hitherto been made to produce the effect of a stereoscopic or three- dimensional image by overlying a plurality of transparen ⁇ cies, each .carrying a part image of a complete object or scene to be viewed stereoscopically.
  • ' techniques hitherto utilised in the preparation of such an image have been expensive and/or not fully successful in achieving a realistic three-dimensional or stereoscopic illusion.
  • an object of the present invention to provide an improved display arrangement of relatively simple form and which gives a realistic three-dimensional impression.
  • Differential percentages of, for example, 40% in the front transparency and 60% in the rear transparency may be employed, and the specific densities may vary according to the nature and size of the display.
  • three or possibly even more superimposed transparencies may be employed, with additional spacer plate(s) 8, and in such a case the three densities could be about 30% to 40% each.
  • the transparencies may be colour separated; one transparency may be printed with a blue/green Image and the other a red/yellow image.
  • the effect of rear illumination may be produced by providing a suitable reflective layer behind the transparencies; thus, ambient or artificial light incident on the front of the assembly will illuminate the superimposed transparencies, and provide a self-contained viewable unit without the need for a light source.
  • the front sheet (7) may comprise a spray coating.
  • the lighting (2) may be disposed, for example, around the periphery of the box to present a tunnel-like effect.
  • the images may be printed on, suitably, the faces of the spacer sheet 8 or on the appropriate faces of sheets 8 and 9.

Abstract

Un affichage optique pour simuler un affichage tridimensionnel, utilisé essentiellement en publicité, comprend un assemblage éclairé par une boîte lumineuse (31) pourvue d'un écran diffuseur (3). L'assemblage comprend une paire de diapositives photographiques (5 et 6) portant des images de densité réduite (5A, 6A) espacées d'environ 1 millimètre grâce à une feuille d'espacement (8). La diapositive arrière (6) est liée à une feuille de support (9) et une feuille frontale (7) protège la diapositive frontale (6). L'assemblage peut être éclairé par la lumière ambiante, auquel cas un réflecteur est monté derrière la feuille de support, et la feuille d'espacement est légèrement opalescente.
