Definitions

  • the invention relates to a display device having the features of the preamble of claim 1 .
  • Such display devices have a viewing surface which is at least partially in the form of a one-way mirror with a translucent side and a reflecting side, with a display for a graphic representation being arranged in the region of the reflecting side.
  • LCD display for displaying a graphic representation, which allows the free choice of any graphic representations, but is associated with high costs.
  • Such LCD displays are only commercially available up to certain sizes, which limits the production of display devices with regard to the possible sizes of the display of the graphic representations.
  • the object of the invention is to provide a display device which can be manufactured at lower cost and is scalable in terms of size.
  • Such a display device has a viewing surface, which is at least partially in the form of a one-way mirror with a translucent side and a reflective side, wherein in the area of the reflective side a display for a can be represented graphically.
  • the display device has an illumination device which is arranged to illuminate at least a portion of the one-way mirror from the light-transmitting side.
  • the graphical representation is
  • the use of at least one template for coding the graphic representation to be displayed enables the display device to be manufactured inexpensively and ensures the scalability of the display device, since templates can be manufactured in any desired size.
  • the coding of the graphic representation is fixed in the template, e.g. B. through corresponding passage openings in the stencil, through which the light of the lighting device can pass unhindered or less hindered than in the remaining area of the stencil.
  • a graphical representation may be encoded in a single template or in at least two templates.
  • the graphical representation can itself be encoded by the arrangement of the individual light sources, preferably LEDs.
  • the graphic representation can be e.g. B. be any alphanumeric characters and / or images.
  • the graphical representation is in the area of the reflecting side of the one-way mirror, it can only be seen by an observer when the lighting is activated, i.e. it is clearly different for a user from the remaining reflecting side of the area of the viewing surface of the display device designed as a one-way mirror.
  • the visible surface can be flat or curved. The same applies to the template.
  • the lighting device is preferably designed not only to illuminate the stencil, but to illuminate the entire surface of the one-way mirror.
  • the lighting device preferably has a multiplicity of preferably punctiform light sources (e.g. light-emitting diodes).
  • preferably punctiform light sources e.g. light-emitting diodes.
  • RGB LEDs a graphic representation in different colors is possible.
  • the use of an LCD display would also be conceivable, but it is provided that the display device does not have an LCD display, at least for displaying the graphic representation.
  • the light sources of the plurality of light sources are at least partially:
  • the latter measure is particularly important when using templates that are constructed in the form of a large number of segments (see below), since the pattern that deviates from a grid pattern can then be specified in such a way that the pattern is at least in the area of a template follows the shape of the segments. This makes it possible to activate only those light sources that are arranged in the area of a certain segment or a certain group of segments, in order to make only these segments appear bright and thus display different information. If time-varying information is to be displayed, different light sources can be activated depending on the time.
  • the arrangement of the light sources in a lattice grid or in a predetermined pattern deviating from a lattice grid is also of importance in the implementation of the invention by coding the graphic representation by means of the light sources themselves.
  • the coding preferably takes place through the targeted activation of light sources; in the second case, the coding preferably takes place through the pattern in which the light sources are arranged.
  • the at least one template can be implemented in a wide variety of forms, e.g. B. as a mask or as a slide or the at least one template can be applied to a carrier layer (z. B. directly on the opaque side of the one-way mirror). In the latter case, the realization of the stencil in the form of an opaque coating or an opaque print is recommended.
  • This is particularly useful if you want to create a graphical display that changes over time, e.g. B. the graphical representation of a clock face with moving hands or a weather station with different symbols for the weather conditions and / or alphanumeric characters for graphical representation of metrological information such as temperature and / or humidity.
  • the different symbols, the possible positions of the pointers or the different alphanumeric characters can be encoded by different segments for this.
  • the display device has a control device which is designed to operate the display device, preferably at least to control the lighting device.
  • the control device can implement a time-varying graphical representation as described above by illuminating individual parts of the at least one template, preferably individual segments.
  • the control device can be used to activate only those light sources from a selection of light sources of the lighting device that are required for coding a desired graphic representation.
  • a communication device for preferably wireless communication (eg an Internet interface and/or a Bluetooth interface).
  • This can be connected to the control device and used to run a computer program stored in an electronic memory, through which software for operating the display device or updates thereof can be loaded into an electronic memory of the display device.
  • a display device can also be used to receive information which can be used as a graphic representation (within the possibilities of at least one template or by the arrangement/activation of the light sources themselves).
  • the display device prefferably has a preferably opaque housing which is closed off on at least one side by the visible surface.

  • FIG. 4 shows a flow chart of the functioning of a computer program for installing and/or updating an operating system of the display device and/or for receiving information for the graphic representation
  • Fig. 1a shows an exploded view of a first display device 1 with a viewing surface 2, which is at least partially in the form of a one-way mirror 3 with a translucent side 4 and a reflecting side 5, with a display for a graphic representation in the area of the reflecting side 5 6, the display device 1 having an illumination device 7, which is arranged to illuminate the one-way mirror 3 from the transparent side 4, the graphic representation 6 is encoded in the form of at least one template 8 arranged on the transparent side 4 of the one-way mirror 3, and the graphical representation 6 is displayed by illuminating the template 8 by means of the illuminating device 7 .
  • template 8 encodes a graphic representation in the form of a logo.
  • the template 8 encodes the graphic representation in the form of a passage opening in an opaque layer through which light from the lighting device 7 can pass, so the remaining part of the reflecting side 5 is dark here.

  • a diffusion layer 10 is arranged between the lighting device 7 and the one-way mirror 3 .

  • the template 8 has a recess in the form of the number 1 here. Only those LEDs which are located behind the recess in template 8 are activated. When changing the stencil, other LEDs can be activated.
  • the template has 8 openings into which z. B. slides or the like can be used.
  • a display device 1 is shown with a graphical representation that changes over time in the form of a clock.
  • the template 8 has a large number of segments, each segment encoding a possible position of the minute and hour hands (a second hand could of course also be provided). By specifically illuminating the individual segments, different times can be displayed as a graphic representation. Contrary to what is shown, the displays associated with the watch, such as hour and/or minute markings and/or the hands themselves, could also be provided as physical components and, in addition to the lighting device provided anyway, other light sources could also be arranged on, on or in the physical components be.
  • the graphical representation is encoded by selectively activating a selection (marked black) of light sources (here LEDs) from all light sources (here LEDs) of the lighting device 7 .
