Definitions

  • the present invention relates to a three-dimensional electroluminescent display with a transparent front part and with an electroluminescent device arranged behind this front part.
  • a three-dimensional electroluminescent display of this type is already known.
  • This previously known device has a transparent pane.
  • the large front surface of this pane is provided with a non-translucent layer in which motifs, such as Graphic,
  • Symbols, pictures or the like can be executed.
  • the front of the motifs is covered with a protective layer, for example made of a clear and hard resin.
  • An electroluminescence device or an EL lamp is assigned to the side of the pane facing away from the motif. This EL lamp is provided with tabs or flags, of which one flag is connected to one of the electrodes of the EL lamp and the other flag to the other electrode of the EL lamp. The EL lamp is supplied with electrical energy via these flags or tabs.
  • the front area of this known device is of complex construction because of the need to use multiple layers.
  • the display device is often required to have a non-flat shape. It is often required that the display should have windows or recesses whose side surfaces should also light up.
  • the EL lamp must be pulled from the front surface of the display to the region of the side walls of this window or this recess.
  • due to the layer structure tending to crack in the previously known display this can only be bent gently.
  • the minimum achievable radius of a curved section of the known display is in the range of approximately 6 mm. This is the case, for example, with panel devices in
  • BESTATIGUNGSKOPIE an automobile has too large a radius. It is also problematic to attach the tabs or flags mentioned to the electrodes of the EL lamp. This is because these electrodes are formed by very thin layers, while the tabs or tab are relatively thick strips of material in comparison with the electrode layers.
  • the object of the present invention is to overcome these and other disadvantages of the prior art.
