Definitions

  • the invention relates to a playback device optical reproduction of information in particular a human viewer, especially for displaying States or switching positions, with a basic element, with a light source arranged on the base element and with at least one the information to be reproduced reproducing, illuminable by the light source Pictogram.
  • Such playback devices are from the prior art Technology known in many ways. For Playback of states or, for example Switch positions of switchgear in particular Light bulbs or light-emitting diodes as light sources Illumination of the state or the switching position reproducing pictograms. To accommodate one Such a light source is usually a housing or a Lamp holder with non-negligible dimensions available. Disadvantage of such a known prior art Technology is that such playback devices only there Can be used where appropriate space for the basic element or the housing with the existing one Light source can be provided.
  • the present invention is therefore based on the object based on a re-input device for optical Reproduction of information to provide almost no space required and especially the Illuminability from side by side or side by side adjacent pictograms at different times enables.
  • the basic element is a base film that as Light source a layer of luminous pigment is present that a first electrode facing the viewer and one Back electrode facing away from the observer is present, wherein the luminous pigment layer between the two electrodes is arranged that by applying a voltage to the Electrodes, the luminous pigment layer at least can be lit in sections and that on the side of the Luminous pigment layer an opaque cover layer is present, which transparent cutouts in the form and size of the at least one pictogram.
  • the transparent cutouts in shape and size of the at least one pictogram is achieved that the made to glow by applying a voltage Luminous pigment layer only the transparent one Recesses, i.e. that compose the pictogram Surfaces, illuminated. This can be a very differentiated and exact illumination of the corresponding pictogram respectively.
  • the basic element is a base film that as Light source a layer of luminous pigment is present that a first electrode facing the viewer and one Back electrode facing away from the observer is present, wherein the luminous pigment layer between the two electrodes is arranged that by applying a voltage to the Electrodes, the luminous pigment layer at least can be lit in sections and that at least one of the two electrodes in shape and size corresponds to at least one pictogram.
  • the particular advantage of such a playback device is that only the locations of the luminescent pigment layer due to the shape and size of one electrode Lights are brought, which the one to be illuminated Correspond to pictogram.
  • the playback device as a dot matrix is executable.
  • the two proposed to solve the problem Playback devices have the particular advantage due to the film and layer-like Construction can be carried out very flat and one Have a thickness of a few 1/10 mm. Besides, are very small, separately controllable areas, which make up the sum of the pictograms, at a short distance realizable to each other.
  • the Back electrode in size and shape to at least one Pictogram, the first electrode being transparent. Due to the transparency of the first electrode ensures that the size and shape of the Back electrode predetermined pictogram by the viewer can be clearly seen and recognized.
  • the Cover layer primarily serves to protect the Playback device and can in particular on the first Be arranged electrode.
  • the cover layer is transparent.
  • the cover layer can be opaque clear cutouts that are at least the size of the at least one pictogram.
  • the first electrode largely transparent conductor foil is between the Cover layer and the luminescent layer is arranged.
  • a such transparent conductor foil has the advantage that the conductor foil over the playback device can extend over a large area and from the cover layer is protected.
  • the back electrode is a conductor layer with at least one Is segment, the at least one segment at least the shape and size of the at least one pictogram corresponds. Due to the segment-like design of the Back electrode is achieved according to the invention that only a section corresponding to the segment of the Luminous pigment layer is illuminated, especially when there is a large area first electrode.
  • the back electrode advantageously a graphite layer.
  • Graphite layer can be opened in a simple way for example a film-like luminous pigment layer Instruct.
  • the cover layer and the luminescent pigment layer at least one layer of paint is present. So that is achieved that the illumination of the at least one pictogram according to the color layer used can.
  • a variant of the invention provides that between the Back electrode and the luminescent layer an insulating layer is arranged. Such an insulating layer may be necessary, to the resistance between the two electrodes, between to which the luminous pigment layer is arranged increase.
  • a further development of the invention is characterized in that that on the side of the Back electrode another insulating layer with cutouts for electrical contacts of the back electrode. Such an additional insulating layer is therefore necessary in order to especially the different segments of the back electrode isolate from each other.
  • the feed lines are made of Are silver or graphite. These materials show a lot good conductor properties and a very low one Resistance to. This enables the playback device run in an energy-saving manner.
  • the individual layers on different Foils are arranged.
  • the individual slides can have very thin wall thicknesses, resulting in a Playback device with a very thin Total wall thickness leads.
  • the individual Layers on a film or several films in the Screen printing process printed on are identical to the individual Layers on a film or several films in the Screen printing process printed on.
  • Such an application the different layers has changed in practice too especially when using only one film proven to be very advantageous and inexpensive.
  • one of the foils can be Be the base film. Which of the different slides as Ultimately, base film is not used crucial since the base film has the task of Playback device to give a certain stability.
  • the Pictograms can easily be made from different Be composed of individual elements. It is also conceivable that a dot matrix can be realized each individual point of the matrix using its own Segments of the back electrode independent of the others Points of the matrix can be controlled.
  • the playback device can especially at switches with a display device for optical reproduction of switch positions Find.
  • the fact that the invention Playback device takes up almost no installation space, can switch with the invention Playback device are provided, according to which the prior art due to the space required known playback devices was not possible, Use playback devices.
  • Such switches can in particular be vehicle switches.
  • vehicle switches the vehicle driver should always have the Switch position must be clearly and unambiguously displayed. On such display or display of the switch position is almost without taking up space through the playback device according to the invention possible.
  • the vehicle switch is a steering column switch with a Shift lever is and that at least one pictogram on the free end of the shift lever is arranged.
  • Steering column switches which have several switch positions can have the use of a playback device according to the invention.
  • the plurality of pictograms are arranged side by side and in different colors can be illuminated. Illumination of the pictograms corresponds to the switch positions of the switch. To this Way the individual functions of the Steering column switch can be easily found. Due to the different illuminations of the different pictograms is a detailed information of the selected Functions or switch positions of the steering column switch possible.
  • the function display is directly in the field of vision of the viewer. An accidentally selected one Switch position of the steering column switch, for example that Switching on the high beam or the parking light can quickly recognized and the switching process can be reversed be made.
