Definitions

  • the invention relates to an arrangement with a passive display surface, in particular a poster or advertising space.
  • Passive display surfaces that are substantially free of self-luminous display elements are used particularly in the field of outdoor and indoor advertising to display information for a variety of purposes, including, for example, publicly disclosed information and advertising.
  • Such displays include, for example, billboard or advertising space, which can optionally be supplemented with self-luminous elements.
  • the back lighting which is also referred to as back lights
  • back lights is always largely lost light energy that is absorbed by the display, such as the paper of a poster.
  • For the illumination of the coming lamps are used to illuminate the display area.
  • the lamps used are in this case arranged laterally offset to or at the edge of the display surface, so as not to disturb the viewing of the display surface by the user.
  • the illumination of is more efficient in the use of light compared to the backlight, but has the problem that the viewing of the display surface may be disturbed by the lighting elements.
  • the object of the invention is to provide an arrangement with a passive display surface, in particular a poster or advertising space, and a passive display surface of the illuminating lighting, in which the problems of the prior art are avoided and the most efficient illumination of the passive display surface is reached.
  • the invention encompasses the idea of an arrangement with a passive display surface, in particular a poster or advertising surface, and a passive display surface of the illuminating illumination, wherein the illumination is formed with a transparent disc arranged in front of the passive display surface and the latter, through which through the passive display surface is visible and on the front of the passive display area in the direction of the passive display surface light emitting, self-luminous lighting elements are formed.
  • the invention therefore provides for arranging lighting elements in the area of the passive display surface, so that these can emit light generated by them when the energy is supplied directly to the opposite display surface and thus to the information presented thereon. This not only allows a space-saving design of the arrangement with passive display device and lighting, but also achieves efficient use of the light generated by the lighting elements to illuminate the information on the display surface. Both the losses which occur during backlighting and long light paths in the case of lateral arrangement of lamps for front lighting are avoided.
  • the arrangement according to the invention can be used in particular in connection with billboard or advertising space in indoor and outdoor advertising. Particular advantages arise in passive display surfaces, which are viewed by the user with a viewing distance of several meters, in particular a distance of at least 3m. Depending on the application, however, the size of the lighting elements can be selected on the transparent pane adapted to the purpose.
  • a preferred embodiment of the invention provides that the lighting elements are designed as predominantly in one direction, namely in the direction of the passive display surface light emitting devices.
  • the light emission takes place exclusively in the direction of the passive display surface.
  • an opaque back for the lighting elements provided be, which prevents light emission on the side facing away from the passive display surface side.
  • Such an opaque layer can then also be used to reflect light emitted from the display surface away, so that this light is at least partially thrown onto the display surface.
  • An opaque back can be made integral with the lighting elements. But even a separate running of the lighting elements layer can be applied to the transparent pane.
  • the transparent pane is, for example, a glass pane or a transparent plastic pane.
  • the lighting elements are formed as light-emitting organic components.
  • Light-emitting organic components are known in particular in the form of light-emitting organic diodes (OLED). These are components that comprise an arrangement of organic layers. To the stack of organic layers, an electrode and a counter electrode are introduced to apply an electric voltage. With the help of electrical voltage, electrical charge carriers in the form of holes and electrons are generated in the stack of organic layers. The electrical charge carriers migrate to a so-called light-emitting layer, in which a recombination occurs with the release of light. With the help of such light-emitting organic components, it is also possible in particular to produce planar luminous elements. The arrangement with electrodes and organic layer stack is produced on a so-called carrier substrate.
  • An advantageous embodiment of the invention provides that the lighting elements are at least partially formed on the passive display surface facing side of the transparent pane. In this embodiment, the light generated in the lighting elements does not have to pass through the transparent pane.
  • a development of the invention provides that the lighting elements are at least partially formed on the side facing away from the passive display surface side of the transparent pane. It is also possible for all the lighting elements to be formed on the side of the transparent pane facing away from the passive display surface. Also, a combination of arranging lighting elements on both sides of the transparent one Disc can be provided. The lighting elements arranged on the side of the transparent pane facing away from the passive display surface can not be troublesome for the closest possible approach of the transparent pane to the display surface.
  • the light-emitting organic components comprise organic diodes according to at least one of the following types: bottom-emitting organic diode and top-emitting organic diode.
  • a light emission can be realized exclusively in the direction of the passive display surface for various configurations of the arrangement of the lighting elements.
  • the light emission takes place through the carrier substrate.
  • the light emission in the top-emitting embodiment takes place exclusively in the direction away from the carrier substrate of the component.
  • the transparent pane is designed to form a carrier substrate for the light-emitting organic components.
  • the transparent pane itself forms the carrier substrate for receiving the light-emitting organic components.
  • a preferred embodiment of the invention provides that the light-emitting organic components are printed on the transparent pane.
  • various manufacturing methods for forming light-emitting organic components are known.
  • the devices can be fabricated by printing on the carrier substrate, providing a wide variety of fabricable illumination structures.
  • the organic layers are deposited by vacuum evaporation.
  • the light-emitting organic diodes are formed as organic elements of the pin type.
  • Organic pin-type devices are characterized in that the transport layers formed for transporting the charge carriers in the stack of organic layers are embodied as doped layers, which are formed by a matrix material and a doping material embedded therein, the latter for optimizing the electrical properties serves.
  • Such organic components are characterized in particular by high lifetimes and optimized efficiency.
  • stacked components in which a plurality of organic light-emitting diodes are stacked. In this way, a higher luminosity can be achieved.
  • An advantageous embodiment of the invention provides that the lighting elements are distributed over the transparent pane in a grid-like manner and free-standing areas.
  • the formation of the grid may be uniform over the area of the transparent pane.
  • it can also be provided to use different raster shapes for different sections of the transparent pane, for example to individually design the illumination of certain sections of the passive display area.
  • a development of the invention provides that with the illumination elements illumination structures are formed in the region of the transparent pane, which at a viewing distance of at least 1m, preferably a viewing distance of at least 2m and more preferably a viewing distance of at least 3m with the naked human eye with average vision are not resolvable. Greater viewing distances are particularly suitable for posters or advertisements.
  • the lighting structures are designed, for example, grid-shaped. In principle, however, it is possible to form arbitrary illumination structures which are not sufficiently resolvable by the naked human eye with average vision, so that the user is not disturbed by viewing the information on the passive display surface by the illumination structures.
  • a voltage supply is formed for the lighting elements, which comprises organic photoelements.
  • the lighting elements which comprises organic photoelements.
  • light-absorbing components which generate electrical energy from them, namely photoelements based on organic layers, are also known.
  • the solar energy be used to power the lighting elements in the transparent pane.
  • the lighting elements are formed as light elements emitting light of different colors.
  • they can be equipped with different light-emitting materials, so as to produce light of different colors, whereby an optically accentuated illumination of the passive display surface is made possible.
  • a preferred embodiment of the invention provides that on the applied by the passive display surface side of the transparent pane light beam leading optical elements are arranged.
  • the light beam guiding, optical elements may be, for example, concave lens elements, which have the supportive effect of avoiding the perception of the lighting elements in the transparent pane by the viewer.
  • light scattering means associated with the lighting elements are formed, which are configured to scatter the light generated in the lighting elements.
  • the light generated by the lighting elements is distributed in an optimized manner over the display area to be illuminated.
  • the associated light scattering means may be integrated into the lighting elements or formed separately therefrom.
  • a light scattering agent for example, light-scattering layers can be used, which are formed in one embodiment by incorporating scattering centers into a transparent layer material. Such layers can be applied, for example, in organic light emitting diodes as an outer layer on the device. But also an outer structuring of a layer for generating a light scattering can be provided.
  • the single FIGURE shows a schematic representation of an arrangement with a passive display surface 1, in which on a front side of a carrier 2, a poster 3 is applied. Opposite the poster 3, a transparent pane 4 designed as a glass pane is positioned. On the poster 3 facing side 5 of the transparent pane 4, a lighting element 6 in the form of a light-emitting organic diode (OLED) is produced, which emits light rays 7 in the direction of the poster 3, whereby the poster 3 is illuminated from the front.
  • OLED light-emitting organic diode
  • a single lighting element 6 is shown to simplify the illustration. Depending on the application, any number of lighting elements can be formed in the area of the transparent pane 4, be it on the side facing the poster 3 or the opposite side 8 of the transparent pane 4.
  • a concave lens 9 is further incorporated into the transparent glass pane 4 on the back of the lighting element 6, which causes the observer to make the lighting element 6 less striking due to the caused by the lens 9 light beam.
  • a cover 10 is provided behind the lighting element 6.
