There is also the possibility that the light emanating from the projectors is deflected by deflecting means, such as mirrors, so that the reference numerals 3 Specify locations where the light is redirected. With the arrows 4 possible directions for outgoing from the projectors or the deflection means light are indicated.

The at least one projector can be mounted in a geometrically meaningful position to be determined in the interior of the vehicle, so that the emitted light is radiated onto the projection surface of the rear component. In this case, the surface to be irradiated can be determined according to the desired control, as well as the image components. For example, it can by a scattering effect of the display area 1 . 2 the content to be displayed is visible and displayed in the backward environment.

In an exemplary embodiment, the at least one projector may also operate at specially stimulating wavelengths and excite translator means such as phosphors or quantum dots embedded in the display surface to force light emission so that the desired signals are radiated into the back space.

The second example of a display device has a display surface 5 on, which is formed on the tailgate of the motor vehicle. In this case, in the second embodiment, the entire rear end is designed as a part. For example, the tailgate may be inserted in the overall part. Alternatively, a design of the rear section may be provided from separate parts.

The rear end may in this embodiment be made of a material that allows light to be transmitted from the inner side of the vehicle to the outside. These may in particular be tinted panes, plastic parts or even switchable glasses or switchable components or switchable films, such as a PDLC or an electrochromatic component.

The entire rear part or parts of the rear part such as the tailgate may be formed as a transparent or semitransparent or switchable transparent part, through which the in 1 apparent display area 5 is realized. This creates the opportunity to display content to be displayed on the entire rear end or part of the rear end.

With displays information and light signals can be broadcast directly, for example, be emitted in the rear environment.

7 shows a schematic representation of possible functions of an embodiment of a display device according to the invention. In the schematically illustrated embodiment, a plurality of projectors 12 provided, whose light is on a display surface 13 incident. Instead of projectors, other imaging systems can be used. By the arrow 14 should be made clear that the on the display area 13 content intended for potential addressees.

7 further clarifies that the display device is a driver and supply unit 15 includes that with the projectors 12 connected is. The driver and supply unit 15 may be part of control means for controlling the display means, in particular for controlling the projectors 12 be. The driver and supply unit 15 is with storage 16 associated with data that may correspond to the content to be displayed.

It is still a signal trigger 17 is provided, which can cause the data corresponding to certain content from the storage means 17 from the driver and supply unit 15 to the projectors 12 to convey the content. The signal trigger 17 can be triggered in different ways. For example, a manual release 18 possible. But it can also trigger via an on-board bus system such as a CAN bus 19 or a wireless interface 20 take place via a radio or infrared transmission. Also a security unit 21 or other unspecified triggering means 22 can the signal trigger 17 drive.

The appearance and nature of the signals supplied to the projectors may vary or may be modifiable. It is also possible to generate the signals event-based, for example, a congestion in advance or weather conditions can influence the generation of the signals.

The data corresponding to the contents to be displayed can be used by the storage means 16 via a wired or wireless storage input 23 be supplied. The data may be from a schematically indicated source 24 which may include, for example, designers, distributors, or the like.

There is definitely the possibility that the storage means 16 not arranged in the motor vehicle.

The display area 13 may be formed, for example, as a modified rear disc, which is equipped with a semi-transparent medium. This medium may have switchable states such as transparent, non-transparent, specular or suitable intermediate states. If a switchable display area 13 Use can be provided coupling with a light generating system of the motor vehicle or its control system. There is, for example, the possibility to dispense with the attachment or integration of conventional taillights, because the display device described can take a light-based signal emission. For example, can thus on the display area 13 a brake light can be displayed.

In this case, as in the embodiment according to 2 the display area 13 be segmented so that brake lights are displayed on the two outer segments, while at the same time the middle segment is in a transmissive state, so that the driver can look out through the middle segment to the rear of the vehicle. The projected brake lights are displayed without dazzling the following traffic. Upon actuation of the hazard warning system, an overlay of the previously projected signal or a re-representation of a specific signal from the memory means 16 be performed so that the flashing signal is visible on the left and right.

ausgeglichen werden kann. Dabei steht E für die Beleuchtungsstärke, I(γ₁) für die Lichtstärke des unter einem Winkel γ₁ einfallenden Lichts, γ₂ für den Winkel zwischen der Ebene der Anzeigefläche und der Richtung des einfallen Lichts, Ω₀ für den Einheitsraumwinkel und r für die Entfernung zwischen der Lichtquelle und der Anzeigefläche.In a further embodiment, the projectors 12 and display areas 13 be coupled and software-based or position-based compensated so that the displayed content receives a homogeneous appearance. In particular, in the case of non-orthogonally illuminated surfaces, inhomogeneities corresponding to the quadratic law of distance can occur $$e=\frac{I\left({\gamma }_1\right)\cdot \text{cos}\left({\gamma }_2\right)}{{\mathrm{<figure-callout\; id="2"\; label="r"\; filenames="DE102017107646A1\_0002.png"\; state="\{\{state\}\}">r</figure-callout>}}^2}\cdot {\mathrm{\Omega }}_0$$

can be compensated. Where E stands for the illuminance, I (γ ₁ ) for the light intensity of the light incident at an angle γ ₁ , γ ₂ for the angle between the plane of the display surface and the direction of the incident light, Ω ₀ for the unit space angle and r for the Distance between the light source and the display area.

The compensation of possible inhomogeneities can be effected, for example, by reducing the maximum permissible luminance of a pixel to the maximum possible luminance of the pixel farthest from the light source or the projector in accordance with the abovementioned distance law. Depending on whether the light sources or the light exit surfaces of the projectors are arranged in one plane or in mutually parallel and spaced or tilted planes, the distribution of the contents to be displayed on the individual projectors and / or segments of the display area can be chosen differently. For example, a division of the content to be displayed on the individual projectors and / or segments of the display surface done. Alternatively, a superimposition of the light emanating from different projectors with opposite courses of the illuminance can be provided.

In particular, a gradient which varies one-dimensionally along the changed distance plane of the display surface during transmission and / or reflection can be used to counteract a drop in illuminance.
