Definitions

  • Laminated display area windshield, display device, and motor vehicle having such a windshield Laminated display area windshield, display device, and motor vehicle having such a windshield
  • the invention relates to a windshield for a vehicle, insbesonde re a motor vehicle, with a peripheral edge area, the edge area containing a black print.
  • the invention also relates to a display device for a motor vehicle and a motor vehicle.
  • windshields are seen as interchangeable elements of a vehicle that have to be replaced frequently. If electronic components are housed in such frequently exchanged components, such as, for example, the laminated displays mentioned, the exchange of a windshield is very expensive. Furthermore, lead frames are visible in windshields with laminated displays, provided the displays are not arranged very close to the edge areas of the windshield. When using curved (OLED) displays, it has been shown that they cannot be integrated into the windshield, or can only be integrated with difficulty, in particular laminated. Head-up displays usually require a relatively large amount of installation space and have the disadvantage that, for example, warning lights cannot be displayed against a dark background. The object on which the invention is based is seen in specifying a windshield in which the above disadvantages in the display of information can be avoided.
  • a windshield for a vehicle in particular a motor vehicle, with a circumferential edge area, the edge area containing a black print. It is provided that the windshield has at least one separate dark display area which is separated from the black print in the edge area, the display area being a film laminated into the windshield.
  • Such a display area can have any shape.
  • a display area configured as a dark film can be used flexibly at desired points on a windshield.
  • the lamination of a dark film in a windshield is an inexpensive process.
  • the windshield does not contain any expensive electronic components, so that an exchange is possible at low cost.
  • the display area can be arranged at a distance from the black print. As a result, the display area is perceived as a kind of floating display. Furthermore, the separation from the black print also makes it clear that the display area is precisely not a part or section of the black print, which is usually arranged or executed as inconspicuously as possible.
  • the display area can be designed like an island in such a way that it is surrounded by transparent sections of the windshield. For example, the display section can be surrounded on three sides by a transparent strip which has a width of a few millimeters.
  • the large transparent pane surface can be arranged on a fourth, in particular upper side of the display area.
  • the dark display area can have a color that has the following values in the CMYK color model:
  • C 0 to 100
  • M 0 to 90
  • Y 0 to 50
  • K 60 to 100.
  • the color of the display area is represented by combinations of values or values that are perceived as black or anthracite gray or dark gray.
  • the display area can thus be laminated into the pane as a black, anthracite gray or dark gray film.
  • a display device for a motor vehicle is also proposed with an optical component that is configured to project information to be displayed, and with a display area that is separate from the optical component and on which the projected information can be displayed or displayed. It is provided that the display area is a dark, in particular black, film laminated in a windshield of the motor vehicle.
  • the display area can be provided above an inner lining element which is arranged below the windshield.
  • the interior trim element can have a recess such that the display area is at least partially arranged in the recess.
  • the interior trim element is in particular the one on which a dashboard and / or a glove compartment and / or a center console of the motor vehicle are provided.
  • the optical component can be arranged below the display area.
  • the optical component can be accommodated in the cladding element or arranged sunk therein.
  • the optical component can project a display of information upward to the dark display area provided in the windshield. From there, the display is reflected or mirrored so that the information can be read from the display area by a vehicle occupant, in particular the driver and / or front passenger.
  • Fig. 1 is a simplified and schematic view of a windshield disc from an interior
  • FIG. 2 shows a simplified and schematic enlargement of the display area shown in FIG. 1;
  • FIG. 3 shows a simplified and schematic sectional illustration roughly corresponding to the section line III-III of FIG. 4;
  • Fig. 4 is a simplified and schematic plan view of a motor vehicle.
  • FIG. 1 shows, in a simplified and schematic representation, a front or windshield 10 of a motor vehicle 12 which is otherwise only partially shown.
  • the motor vehicle 12 is represented by way of example by indicated side windows 14 and front body struts (A-pillars) 16. There is also a steering wheel 18 shown.
  • a cladding element 20 of the motor vehicle 12 is shown below the windshield 10.
  • a dark display area 22, shown here as an example in pure black, is arranged in the windshield 10.
  • the display area 22 forms a type of dark island within the otherwise transparent windshield 10.
  • Information, in particular vehicle-relevant data, can be displayed on the display area 22.
  • the display area 22 serves to mirror or reflect display elements which are projected onto the display area 22 by means of an optical component not visible in FIG. 1.
  • the display area 22 is therefore not an active display with display elements, such as light-emitting diodes or the like, but a passive display area which is provided in the area of the windshield 10.
  • the display area 22 has a trapezoidal shape with rounded corners.
  • the display area 22 can have its greatest extent in the width direction X of the windshield 10.
  • the display area 22 can have any shape, that is to say, for example, rectangular or polygonal or elliptical or the like. It is also conceivable that the display area 22 is arranged along a lateral edge of the windshield such that it has its greatest extent in the longitudinal direction along the windshield 10.
  • the display area 22 can also be designed as a type of angle with one leg that extends in the width direction and one leg that extends in the longitudinal direction.
  • the windshield 10 usually has a black print 24 along its circumferential edge area, which is illustrated in FIG. 2 with vertical hatching.
  • the display area 22 is provided separately from the black print 24.
  • the display area 22 is correspondingly surrounded by a transparent pane section 26.
  • the display section 22 acts like an island within the windshield 10. In relation to a visible upper edge 28 of the interior trim element 20 It can also be said that the display area 22 can be perceived as floating in the windshield 10.
  • the cladding element 20 has a recess 30.
  • the recess 30 has a shape that is complementary to the shape of the display area 22.
  • the display area 22 can be arranged somewhat lower, so that a larger transparent pane surface remains above the display area 22 and the driver's field of vision is not severely impaired.
  • the provision of a recess 30 is, however, an option that must be present.
  • Fig. 3 shows in a simplified and schematic sectional view, which corresponds approximately to a section line III-III of FIG To radiate or project to display area 22.
  • the display area 22 reflects or mirrors the information displayed by the optical component so that the information can be read from the display area 22 for a vehicle occupant, in particular a driver of the motor vehicle 12.
  • the beam path of the information displayed is marked in a greatly simplified manner by the arrows IA.
  • the display area 22 is designed as a dark or black film.
  • the film is laminated in the windshield 10, which is illustrated in the sectional view in FIG. 3. 3 shows the proportions, in particular special thicknesses, of windshield 10 and display area or film 22, not to scale.
  • the information projected onto the display area 22 by means of the optical component 34 can reproduce various vehicle-relevant parameters.
  • fog. 2 shows by way of example a speed display 37, a range display 38 and a warning symbol 40 as a representative for different warning signals that can be output or shown.
  • the in Fig. 2 The information 36, 38, 40 shown are purely exemplary and other information can also be displayed. For example, short scrolling texts that provide information about traffic disruptions or the like could also be displayed on the display area 22.
  • the optical component 34 is connected to a vehicle control device 42, which is only shown schematically in FIG. 3.
  • the vehicle control device is set up to control the optical component 34 in such a way that the desired information is projected and displayed on the display area 22.
  • Fig. 4 shows a simplified and schematic view of a motor vehicle 12 in a plan.
  • the black print 24 can be seen, which is provided on the windshield 10 around the circumference.
  • a display area 22 is also shown in a simplified manner, which is arranged as a dark or black film in the windshield 10.
  • the inner lining element 20 and the steering wheel 18 can be seen.
  • the concept presented here of a windshield with a passive, in particular reflective or mirror-acting display area 22 enables the windshield 10 to be replaced inexpensively .
