Definitions

  • the aim of the present application is to avoid these disadvantages and to provide a screen which is to be irradiated with "ordinary" light and, moreover, gives a good aureola. 25
  • This aim is achieved with a screen as described above, in that the plastic sheet material is opalescent and has at least one light-excluding layer applied thereon, provided with openings essentially corresponding to the symbols to be displayed.
  • the plastic sheet material is opalescent and has at least one light-excluding layer applied thereon, provided with openings essentially corresponding to the symbols to be displayed.
  • the light-excluding layer serves to produce the
  • This aureola effect can also be intensified in that the plastic sheet material contains fluorescent pigments. It is also possible, in place thereof, to apply a layer of fluorescent material over the openings. If it is desired to avoid so-called "colour contamination" of the plastic sheet material, that is to say that the colour of this sheet material is balanced out, provision is made, according to a further advantageous embodiment, that a layer which covers the opalescent sheet and is provided with openings essentially corresponding to the symbols to be displayed is applied between the plastic sheet material and the light-excluding layer. In this way, both an improved aureola effect and the preservation of colour of the plastic sheet material are achieved.
