Definitions

  • the invention relates to a display instrument, in particular in a motor vehicle, with at least one light source for illuminating a display area and an organic one or polymeric display (OLED or PLED), which has individually controllable areas.
  • OLED organic one or polymeric display
  • Organic or polymeric displays have a very high light output in the order of 200 - 600 cd / m 2 , so that in contrast to liquid crystal displays, no lighting is required to make the display visible in poor light or in the dark. For this reason, such organic or polymeric displays have already been described as displays in motor vehicles, for example in the form of displays from radios.
  • Today's display instruments for motor vehicles usually have in addition to the display, for example for a pixel representation, at least one further display area on, for example, a dial for a speedometer or for a tachometer or for one Tank level or cooling water temperature display. Therefore So far you can see lighting for such display areas with its own light source - in particular an incandescent lamp or light emitting diode - in front, if necessary can be turned on, which requires considerable effort conditional because the light source of this additional lighting z. B. with a power supply and with control means must be provided, i.e. additional mechanical and electrical adjustment required.
  • the invention is based on the problem of a display instrument of the type mentioned with an organic or polymeric display and at least one of one Light source electrically illuminated display area too develop in which the lighting of the display area can be achieved with as little effort as possible.
  • the display instrument By designing the display instrument so there is no separate light source for the display area be an active, i.e. H. controllable, Area of the display as a light source for the display area used.
  • This display area is preferred an analog display area, e.g. B. a dial of a Analog pointer or an illuminable analog pointer itself. Since the display is already in contact with a Printed circuit board connected and control electronics for the display must be present, requires control the area of the display serving as the light source essential additional structural effort, so that the display instrument according to the invention very simple and can be compact.
  • the organic or polymer Display only needs one over the visible area outstanding, actively controllable supernatant, so that the area serving as the light source is provided there can be.
  • the display is used as a pixel matrix display device is trained. Then you can this display for example to show the time, fuel consumption or other digital information and optionally also as a quasi-analog display.
  • the display can be used for any kind of Illumination of display areas can be used, in particular for slit light, transmitted light or incident light on dials and pointers.
  • Illumination of display areas can be used, in particular for slit light, transmitted light or incident light on dials and pointers.
  • Instruments in motor vehicles is the display instrument trained and can be particularly simple the appearance of the previously used display instruments have if according to another development of the invention the display area serving as a light source Coupling surface of an optical fiber is opposite that for transmitted light illumination of the other display area is trained.
  • the transmission of the light from the display via a Light guide behind a display area for lighting this display area in the transmitted light process is special advantageous if the further display area Dial of a pointer instrument is. advantageous the further display area can also be illuminated Be the pointer of a pointer instrument.
  • Such a display instrument is particularly simple in construction designed when the display is between a circuit board and the dial and the viewing area the display of wall surfaces one of the dial to the display leading shaft is limited.
  • Figure 1 shows a circuit board 1, on the at a distance to the circuit board 1 by means of holders 2, 3 a display 4 is attached.
  • This display 4 is an organic or polymeric display 4 so that its controlled display areas with high light output to shine.
  • a flexible film 5 connects the display 4 electrically with the circuit board 1.
  • FIG. 1 also leaves a partial area of one Recognize display area 17 of the dial 6 of from a shaft 9 delimited by wall surfaces 7, 8 leads to the display 4 and there limits a viewing area 10.
  • the display 4 has a display area 11, which can be controlled separately and the function of a Has light source.
  • This display area 11 is opposite there is a coupling surface 12 of a light guide 13, for illuminating the dial 6 in the transmitted light process serves.
  • the light guide 13 can also nor for coupling light into one here shown, playing in front of the dial 6, illuminable Serve pointer.
  • the top view of the display 4 shown in FIG. 2 shows the viewing area 10 with a numerical display 14.
  • the display area 11 is above the viewing area 10 to recognize that for coupling light in the in Figure 1 Light guide 13 shown is used.
  • a further display area 15, 16 is provided that can also be controlled separately and as Light source for additional display areas, not shown serves.
