Drawings

The above and other features of the present utility model will become apparent with reference to the accompanying drawings, in which,

fig. 1 shows in a schematic view an embodiment of a curved display device according to the utility model.

Detailed Description

It is to be understood that, according to the technical solution of the present utility model, those skilled in the art may propose various alternative structural modes and implementation modes without changing the true spirit of the present utility model. Accordingly, the following detailed description and drawings are merely illustrative of the utility model and are not intended to be exhaustive or to limit the utility model to the precise form disclosed.

Terms of orientation such as up, down, left, right, front, rear, front, back, top, bottom, etc. mentioned or possible to be mentioned in the present specification are defined with respect to the configurations shown in the drawings, which are relative concepts, and thus may be changed according to different positions and different use states thereof. These and other directional terms should not be construed as limiting terms. Furthermore, the terms "first," "second," "third," and the like are used for descriptive and distinguishing purposes only and are not to be construed as indicating or implying a relative importance of the corresponding components.

Referring to fig. 1 (which shows a schematic view of a curved display device according to an exemplary embodiment), a curved display device 100 of this type includes a display element 110, a reflective element 120, a light guiding element 130, a covering element 140, and a base 150, wherein the display element 110 includes a light-emitting surface (a lower surface thereof in the drawing) configured to emit light (i.e., for presenting display content) and a rear surface (an upper surface thereof in the drawing) not configured to emit light. The reflective element 120 here comprises a curved reflective section 121 and is arranged relative to the display element 110 in such a way that it faces the light exit surface of the display element 110 and the light emitted by the light exit surface is reflected by the curved reflective section 121. Around the periphery of the reflective element 120 is a light guide element 130 that is light transmissive and allows light from the reflective element 120 within to exit into the surrounding environment. The cover member 140 can be used to cover the display element 110 and other internal structures of the curved display device 100 from the surrounding environment.

By combining the curved reflective section 121 with the light-guiding element 130 arranged therearound, a large viewing angle, in particular a circular 360 ° viewing angle, can be achieved in a simple manner, and thus a better display effect can be presented independently of the position of the user. For example, in the case where the curved display device 100 is used as an atmosphere lamp, the viewing angle achieved by it can involve passengers in both front and rear rows.

It should be noted here first that the term "annular" as used herein is to be understood as a substantially end-to-end, closed shape, however, this is not limiting on its particular geometry, and can take the form of a torus, rectangular closed shape, triangular closed shape, or other form of closed shape. In the embodiment shown in the drawings, the light guiding element, the display element and the reflective element have a circular cross section in their direction perpendicular to the central axis.

The display element 110 can optionally be configured as a display screen which communicates with a vehicle control unit and changes the display content on the basis of signals from the vehicle control unit, in which the respective display content is stored. When the curved display device 100 is in operation, relevant display content may be retrieved from the vehicle and presented to the user. For example, the display element 110 as a display screen can communicate with the vehicle control unit in a wired manner or in a wireless manner. For example, in the embodiment shown in the drawings, the drive circuit board 111 assigned to the display element is communicatively connected to the vehicle control unit via a cable (which is only schematically shown in solid lines in the drawings), wherein the drive circuit board can be used to control the display element to normally display video signals. In addition, the wireless communication mode can be realized through Ethernet, local area network or intelligent gateway.

In this case, the content presented by the display element 110 can relate to dynamic or static images. Further, in order to improve the image fidelity presented by the curved surface reflection section 121, the display content stored in the vehicle control unit can be subjected to the anti-distortion processing in advance, that is, a distorted image is generated in an inverse manner according to the reflection characteristics of the curved surface reflection section 121, in such a manner that a distortion problem that may occur in the image presented to the user can be eliminated.

In a possible embodiment, the display element 110 can be actuated by the user, i.e. the user can change the display content by means of an associated input device, which can be configured as a physical actuating element, which can optionally be arranged at the cover element 140 and can be embodied in a simple manner as a corresponding key or touch key. In particular, in the case of the cover element 140 made of a light-impermeable material, on its outer side (i.e. its outer side facing away from the display element and toward the surroundings) there are corresponding user-operated keys or touch keys which communicate with the drive circuit board of the curved display device 100 or with the vehicle control unit via communication lines. Here, a manufacturer's logo or pattern may also be provided on the cover element 140. Of course, the separate operating element is not necessary, and its operating function can be integrated on a unified operating panel.

Furthermore, the input of operating commands to the curved display device 100 can also be achieved by external devices, for example smart phones of the user, bluetooth devices, which is particularly advantageous in particular in designs in which the cover element 140 is likewise embodied to be light-permeable and is assigned a separate display element. In this way, not only can operations by a user who is remote from the curved display device be achieved, but also the aesthetics of the curved display device can be improved.

As regards the reflective element 120, its curved reflective section 121 can be configured as a concave reflective section, or as a convex reflective section, or as a free-form reflective section, as desired.

Specifically, taking a concave reflecting section as an example, the curved reflecting section 121 is concavely configured in a direction away from the light-emitting surface and extends around the central axis thereof, as shown in the drawings, the reflecting element 120 is configured in a volcanic shape as a whole and forms the curved reflecting section 121 toward the outside of the light guiding element 130 and the display element 110. The reflective element 120 as a whole can be made of a material that reflects light and the curved reflective section 121 is an integral part thereof, or only on the outside of the reflective element 120, in particular only on the outside of the curved reflective section 121, is coated with such a material layer. The curved reflective section 121 is preferably implemented as a smooth mirror with high reflectivity for reflecting light rays from the display element 110.

Alternatively, the display element 110, in particular its light exit surface, is ring-shaped, in accordance with which the curved reflective section 121 has a likewise ring-shaped cross section in a plane perpendicular to the central axis (which extends in the vertical direction in the drawing), the display element 110 being arranged concentrically with the curved reflective section 121. In this embodiment, the display element 110 can be mounted on the light-guiding element 130 surrounding the reflective element 110 and connected, in particular glued, with its outer circumference to the cover element 140. Here, the light guide element 130 can protect the reflection element 120 enclosed by it.

Optionally, the reflective element 120 further comprises a fastening section 122 for fastening to the base 150, which transitions smoothly into the curved reflective section 121 and is configured essentially flat. By means of the fastening section 122, the reflective element 120 can be detachably connected to the base 150, for example by means of a threaded fastener, or a snap connection, or a glue connection. In the embodiment of the flat fastening section, a larger contact surface area can be achieved and thus the connection reliability is increased.

In the assembly process, the reflecting element 120 is first fixed on the base 150; the light guide element 130 is then disposed on the outer periphery of the reflecting element 120, in particular, around the outer periphery of the reflecting element 120; next, the display element 110 and the cover element 140 are placed on the light guide element 130; the cover member 140 and the display member 110 are then fixed and attached.

Furthermore, when the reflective element 120 is formed as a mirror, it can be associated with a special support for supporting and fixing it. Alternatively or additionally, the reflector can be adhesively connected with its outer circumference to the light-guiding element.

Alternatively, the cover element 140 can be configured in the manner of a dome, i.e., it has the shape of a truncated sphere, a receiving space being formed between the cover element 140 and the display element 110 located therebelow, in which receiving space the drive circuit board 111 associated with the display element is arranged. The driving circuit board 111 may be fixed to the rear surface of the display element 110. In this way, the space utilization of the curved display device can be optimized.

In case of a wired connection of the drive circuit board 111 with the vehicle control unit, the relevant cables of the drive circuit board 111 can protrude into the outside through the centrally located reflective element 120. When the reflective element 120 is configured as a hollow wall element, the cable can extend directly through the interior of the reflective element to the exterior, wherein the reflective element 120 itself has a through-hole through which the cable passes, see fig. 1. When the reflective element is configured as a solid element, for example, it can be provided with a curved reflective section only on the outer circumferential surface, a through hole can be provided in the center thereof for the cable to pass through.

In summary, the curved display device according to the present utility model can achieve a larger viewing angle in a simpler manner and thus can provide a superior display effect independent of the spatial position of the user. In an embodiment of the curved display device, the reflective effect of the reflective element can be controlled more accurately by arranging the display element and the reflective element concentrically. In another embodiment of the curved display device, the space utilization can be further optimized by improving the arrangement of the driving circuit board and the cables of the display element. In a further embodiment of the curved display device, by providing the operating element, a user's operation thereof can be achieved in a simple manner.

The utility model furthermore relates to a vehicle comprising such a curved display device, which is capable of having the features and advantages set forth above. The curved display device can be arranged in any desired position in the vehicle cabin, for example at the vehicle main dashboard, in which case it can be placed in its seat and fastened in the vehicle exterior trim. The description of the vehicle according to the present utility model can be referred to correspondingly for the description of the curved surface display device, and will not be repeated.

It should be understood that all of the above preferred embodiments are exemplary and not limiting, and that various modifications or variations of the above-described specific embodiments, which are within the spirit of the utility model, should be made by those skilled in the art within the legal scope of the utility model.
