Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) These and other aspects and advantages will become more apparent and more readily appreciated from the following description of example embodiments, taken in conjunction with the accompanying drawings, of which:

(2) FIG. 1 is a schematic perspective view of an embodiment of a display apparatus having a plurality of integrated electrical components;

(3) FIG. 2 is a further schematic perspective view of an embodiment of the display apparatus having a plurality of integrated electrical components; and

(4) FIG. 3 is a schematic perspective view of an embodiment of a detail from a motor vehicle having an embodiment of the display apparatus.

DETAILED DESCRIPTION

(5) The example embodiments explained below are merely example. In the example embodiments, the described components of the embodiments are each individual features that should be considered independently of one another, that each also develop the disclosure independently of one another and hence that should also be regarded as part of the disclosure individually or in a combination other than that shown. In addition, the embodiments described are also able to be supplemented by other features from those already described.

(6) In the drawings, elements having the same function are each provided with the same reference signs.

(7) FIG. 1 shows a schematic perspective view of an embodiment of a display apparatus 1. The display apparatus 1 has a light source 2 that can be used to project light rays 3 onto an imaging area 4 of a film 5.

(8) In the example embodiment, the film 5 is presented in square form, for example. The respective corners of the film 5 have camera elements 6 arranged in them that use optical fibers 7 to transmit captured light rays to a camera device 8 of the display apparatus 1. For example, the camera elements 6 and the camera device 8 form a camera 9. The camera 9 can be used to capture surroundings 17 (FIG. 2) of the display apparatus. By way of example, movements of a person can be captured by the camera 9, the movements being able to be used to control the display apparatus 1 and/or further components of a motor vehicle 26 (FIG. 3).

(9) Further, the display apparatus 1 can have a control device 10 that can be used to control the display apparatus 1. By way of example, the camera 9 here can send the information to a computer unit 11 of the control device 10, which then produces a three-dimensional image model, for example, in an imaging unit 12. This model can then in turn be presented as an image 16 on the film 5, for example in the imaging region 4.

(10) The image 16 can, for example, be presented as augmented reality, so that the surroundings 17 of the display apparatus 1 and the image 16 are perceptible to a person. The image 16 can, for example, be presented as a three-dimensional image 16, for example, as a hologram.

(11) FIG. 2 shows a further schematic perspective view of an embodiment of the display apparatus 1. The film 5 is arranged on a carrier element 13, which is in semitransparent form, for example. For example, regions of the film 5 can be arranged on the carrier element 13. There is provision for the film 5 to incorporate at least one further electrical component 2, 9, 10, 18, 19, 20, 21, 22, 25 of the display apparatus 1.

(12) For example, the carrier element 13 can be produced in a sandwich design, so that for example a further carrier element can be arranged on the film 5. For example, the display apparatus 1 can then be in the form of a window 14 of a motor vehicle 26 (FIG. 3). For example, the window 14 can include a safety glass, for example, so that it is suitable for motor vehicle construction.

(13) Further, there can be provision for an LCD film 15 to be arranged on the carrier element 13 and/or on the film 5 and to be able to generate shading, so that the image 16 can be presented on the imaging region 4 in an improved manner or is perceptible to the person in an improved manner. For example, there can furthermore be provision for the LCD film 15 to be arranged on a carrier element 13 as well, the LCD film being dimmable on a pixel-by-pixel basis, so that depth information of the film 5 is perceptible to the person in an improved manner. For example, the LCD film 15 can dim only the regions on which an image 16 or parts of the image 16 are also presented, so that the person can continue to see through the regions where no image 16 is presented.

(14) FIG. 2 furthermore shows that at least one electrical power supply element 18 of an electrical power supply 19 of the display apparatus 1 for suppling the display apparatus 1 with electric power can be incorporated in the film 5 as well.

(15) Further, there can be provision for at least one solar cell element 20 to be incorporated in the film 5 as the at least one electrical power supply element 18 for the purpose of electrical power supply in the display apparatus 1.

(16) Further, there can be provision for at least one induction element 21 and/or an electrical contact element 22 to be incorporated in the film 5 as the at least one electrical power supply element 18. The induction element 21 can be used to receive electric power from a further induction element 23 (FIG. 3), and/or electric power from a further contact element 24 (FIG. 3) can be receivable by use of the electrical contact element 22.

(17) Further, the film 5 can include a communication device 25 for receiving, for example for wirelessly receiving, for example by use of Bluetooth or WiFi, information at least about the image 16, wherein the communication device 25 is incorporated in at least regions of the film 5. It is furthermore possible for the communication device 25 to be able to be used to transmit, for example wirelessly, further information, for example from the camera 9 and/or an operating status of the display apparatus 1, to a further component, for example, of the motor vehicle.

(18) FIG. 3 shows a further schematic perspective view of an embodiment of a detail from a motor vehicle 26. The motor vehicle 26 in the example includes the display apparatus 1 and a motor vehicle subassembly 27. Further, the carrier element 13 is in the form of a window 14, for example in the form of a windshield. For example, the further induction element 23 and the further contact element 24 may be arranged at a coupling point 28 between the window 14 and the motor vehicle subassembly 27, so that electric power can be transmitted to the display apparatus 1. It is also possible for further elements for control or transmission of information to or from the display apparatus to be arranged on the motor vehicle subassembly 27, for example at the coupling point 28.

(19) Overall, the examples show how the display apparatus allows the incorporation of the imaging elements and electronics into the window.

(20) A description has been provided with reference to various examples, but it will be understood that variations and modifications can be effected within the spirit and scope of the claims which may include the phrase “at least one of A, B and C” as an alternative expression that means one or more of A, B and C may be used, contrary to the holding in Superguide v. DIRECTV, 358 F3d 870, 69 USPQ2d 1865 (Fed. Cir. 2004).
