The at least one display device includes a display field for optically representing a display content, wherein the display field and/or the display device is/are enclosed by a visible frame, wherein the visible frame is delimited by an inner periphery and also by an outer periphery. The at least one section of the outer periphery defines at least one line on the cover plate by way of parallel projection along an axis, which is oriented perpendicularly to the cover plate. The at least one light-guide structure module is configured to enlarge or zoom the display content of the at least one display device and to project the at least one section of the first inner periphery of the visible frame and consequently of the display field onto the at least one defined line of the cover plate, wherein only the display content of the at least one display field is representable by way of the cover plate.
In general, the at least one light-guide structure module is arranged on the at least one display device, and the cover plate is arranged on the at least one light-guide structure module.
In the case of an optical representation or display of a display content of the at least one display device by way of the at least one light-guide structure module and the cover plate, the frame of the at least one display device is masked out.
The display system in a refinement includes a plurality of display devices, wherein provision is made, for two display devices which are in general immediately adjacent to one another, of the fact that at least one section of a second outer periphery of a visible frame, which encloses a display field of a first display device, and at least one section of a second outer periphery of a visible frame, which encloses a display field of a second display device, are immediately adjacent and/or abut at at least one common section, for example. Depending on the definition, in each case one display device is enclosed here by the frame. Alternatively or in addition, the frame, which encloses at least the display field of a respective display device, is configured as a component of the display device. The at least one common section and the two sections of the outer peripheries of the frame of the immediately adjacently arranged display devices are arranged on a straight line. In addition, this at least one common section defines, by way of a parallel projection along an axis that is perpendicular to the cover plate, the at least one line of the cover plate, wherein the line extends on an outer surface of the cover plate which faces away from the at least one light-guide structure module, whereas an inner surface of the cover plate, which is arranged parallel to the outer surface, faces the at least one light-guide structure module and is in contact therewith in an embodiment. It is here also possible that the at least one for example virtually defined or definable line is arranged on the inner surface of the cover plate.
The at least one light-guide structure module is embodied to project the at least one section of the first inner periphery of the visible frame, which delimits or encloses the display field of the first display device, and the at least one section of the first inner periphery, which delimits or encloses the display field of the second display device, onto the or onto the same at least one line of the cover plate. The at least one common section of the second outer peripheries of the two visible frames of the display fields defines, by way of parallel projection along the axis, the at least one line of the cover plate.
Provision is furthermore made of the fact that at least one section of a second outer periphery of the visible frame, which encloses or delimits the at least one display field, wherein the at least one section of the second outer periphery of the visible frame defines the at least one line of the cover plate by way of parallel projection along the axis, which is perpendicular to the cover plate and extends along an edge of the cover plate. The at least one light-guide structure module is embodied to project the at least one section of the first periphery of the visible frame, which delimits the display field of the at least one display device and is assigned to the at least one section of the second outer periphery of the visible frame, onto the at least one line along the periphery of the cover plate.
In general, each display device is assigned a light-guide structure module. The one light-guide structure module is arranged between the respective display device to which it is assigned and the cover plate. In the case of the two immediately adjacently arranged display devices, provision is made of the fact that two light-guide structure modules are likewise arranged immediately adjacently. A first light-guide structure module, which is assigned to a first display device, is embodied to project the at least one section of the first inner periphery of the visible frame, which delimits or encloses the display field of the first display device, onto the, or onto the same, at least one line of the cover plate, wherein the at least one common section of the second outer peripheries of both visible frames of the display fields of both generally immediately adjacent display devices defines the at least one line of the cover plate by way of parallel projection along the axis, which is perpendicular to the cover plate. A second light-guide structure module, which is assigned to a second display device, is embodied to project the at least one section of the first inner periphery of the visible frame, which delimits or encloses the display field of the second display device, likewise onto the, or onto the same, at least one line of the cover plate, wherein the at least one common section of the second outer peripheries of both visible frames of the display fields of both generally immediately adjacent display devices and the at least one line of the cover plate are parallel with respect to one another.
The at least one light-guide structure module is arranged between the at least one display device and the cover plate and has a body having a first outer side, which faces the at least one display device, and a second outer side, which faces the cover plate. The two outer sides are here arranged mutually parallel, wherein the first outer side has a smaller surface than the second outer side. At least one section of at least one edge of the first outer side of the at least one light-guide structure module is assigned to the at least one section of the at least one first inner periphery of the visible frame of the display field of the at least one display device, wherein the first outer side of the at least one light-guide structure module and the display field of the at least one display device are congruent and face one another. In addition, at least one section of at least one edge of the second outer side of the at least one light-guide structure module is assigned to the at least one section of the at least one line of the cover plate, wherein the at least one line is defined by way of parallel projection of the at least one section of the second outer periphery of the same visible frame along the axis, which is oriented perpendicularly to the cover plate. The frame is delimited by the same at least one section of the first inner periphery that is assigned to the at least one section of the first edge of the first outer side of the at least one light-guide structure module.
In a configuration, the at least one display device includes an n-polygonal display field for representing a display content. For example, n in the term n-polygonal here refers to any desired natural number, for example three, wherein the display field is for example triangular. The inner periphery of the visible frame and the outer periphery of the visible frame, which are arranged parallel with respect to one another, are here likewise n-polygonal. In a configuration, the sections of both peripheries of the visible frame are assigned to one another, wherein the at least one section of the first inner periphery also delimits the display field of the at least one display device and/or the at least one display field. The peripheries of a frame are generally arranged mutually parallel, wherein the outer periphery encloses the inner periphery. A display surface of the display device has an angled, for example quadrangular, design in an embodiment, that is to say for example rectangular or square. The peripheries of the frame of a display device have a correspondingly angled design, wherein an inner periphery has the same lateral length as an outer edge of a display field. Peripheries of an angled frame, which encloses an angled display field, are straight here. Accordingly, the at least one line of the cover plate and the common section of the outer peripheries are straight.
It is possible here that the at least one light-guide structure module between the at least one display device and the cover plate has a body in the shape of a truncated pyramid. The two outer sides of such a body, having the shape of a pyramid, of the at least one light-guide structure module are likewise n-polygonal, generally quadrangular, for example rectangular, in accordance with a shape of the display field of the at least one display device, to which the at least one light-guide structure module is assigned.
In the display system, the cover plate is embodied in the form of a cover glass. The cover plate is made of a transparent material, which is for example glass or plastic.
The display system is usable in a vehicle and/or for a vehicle and is arrangeable on an inner wall in an interior space of the vehicle.
The at least one light-guide structure module is configured to refract the light, by way of which the display content of the display field of the at least one display device is provided, and to thus enlarge the display content. Here, the at least one light-guide structure element, for example in the form of a prism which has the shape of a truncated pyramid and/or is trapezoidal in cross section, is embodied in the form of a light control film and/or a holographically optical element, and is made for example of plastic.
The method described herein is provided for optically representing a display content using a display system which has at least one display device, at least one light-guide structure module and a cover plate, wherein the at least one light-guide structure module is arranged between the at least one display device and the cover plate, wherein the at least one display device includes a display field for representing a display content, wherein the display field is enclosed by a visible frame, wherein the visible frame is delimited by a first inner periphery and also by a second outer periphery. In the method, at least one line is defined on the cover plate by way of at least one section of the outer periphery of the visible frame by way of parallel projection along an axis, which is oriented perpendicularly to the cover plate.
The display content of the at least one display device is enlarged with the at least one light-guide structure module, wherein the at least one section of the first inner periphery of the visible frame and consequently of the display field is projected by the at least one light-guide structure module onto the at least one line of the cover plate, wherein only the display content of the at least one display field is represented by way of the cover plate and the typically visible frame is masked out.
The method in a configuration is provided for representing a display content which is common for at least two display devices. Here, provision is made, for two generally immediately adjacent display devices, of the fact that at least one section of a second outer periphery of a visible frame, which encloses a display field of a first display device, and at least one section of a second outer periphery of a visible frame, which encloses a display field of a second display device, are generally immediately adjacent and/or abut at at least one common section. The at least one common section defines the at least one line of the cover plate by way of parallel projection of an axis, which is oriented perpendicularly to the cover plate. The at least one line extends on an outer surface of the cover plate which faces away from the at least one light-guide structure module, whereas an inner surface of the cover plate, which is arranged parallel to the outer surface, faces the at least one light-guide structure module and is in contact therewith in an embodiment. The at least one section of the first inner periphery of the visible frame, which delimits or encloses the display field of the first display device, and the at least one section of the first inner periphery, which delimits or encloses the display field of the second display device, are projected by the at least one light-guide structure module onto the, or onto the same, at least one line of the cover plate which is parallel to the at least one common section of the second outer peripheries of the two visible frames of the display fields of the two generally immediately adjacent display devices.
In an embodiment of the method, provision is made for each of the display devices to be assigned a light-guide structure module, wherein display contents from in each case two generally immediately adjacent display devices are connected by way of the light-guide structure modules, which are assigned to the two display devices, to form the common display content.
In addition, the display contents of the two generally immediately adjacent display devices are connected by the light-guide structure modules along the at least one common line to form the common display content, wherein the at least one common section of the second outer periphery of the visible frame and the at least one line of the cover plate are parallel with respect to one another.
As already described above, it is possible that each of the display devices of the display system is assigned a light-guide structure module which is typically in the shape of a truncated pyramid. It is here possible in a refinement of the method that individual display contents from in each case two generally immediately adjacent display devices are connected by way of the light-guide structure modules, which are assigned to the two display devices, to form the common display content and are thus fused.
In this respect, it is furthermore possible that the display contents of the two generally immediately adjacent display devices are connected by the light-guide structure modules along a typically common line on at least one of the surfaces of the cover plate, that is to say the inner and/or outer surface, which with respect to a common section of the second outer peripheries of the two generally immediately adjacent display devices to form the common display content, wherein the common section and the at least one line of the cover plate are parallel with respect to one another.
In a configuration it is possible that the display system includes a plurality of display devices, wherein each display device has a display field, which is surrounded by a visible frame and on which a light-guide structure module is arranged. The plurality of light-guide structure modules of the display system are used to connect individual display contents of display fields of the display devices to form one display content which is common for all display devices. The individual display contents of generally immediately adjacent display devices are here composed along the common line on the cover plate by the light-guide structure modules to form the common display content. It is thus possible to compose a plurality of display contents of the plurality of display devices to form the common display content. The frames, which enclose the display surfaces of the display devices, are here masked out by the light-guide structure modules.
With the display system, a display arrangement is provided, in which displays or monitors and thus display fields or screens of at least two display devices are fused.
The display system is able to be integrated for example in a vehicle and is typically used as a design element. It is possible with the display system to represent a plurality of display fields without peripheries. It is also possible to compose display contents of individual display fields to form a larger common display content on the cover plate of the display system.
Typically, a plurality of individual display devices are modularly composed to provide the display system, wherein provision is made for the use of display devices having display fields which are enclosed in each case by frames. It is possible here to use identically designed display devices for a display system, which have the same dimensions, a plurality of times.
Using the display system, display contents of typically immediately adjacently arranged display devices are seamlessly composed. In a refinement, a light-guide structure module is arranged on each display device between the respective display device and the cover plate. Provision is made here of the fact that the first outer side of the body, which for example has the shape of a truncated pyramid, of a respective light-guide structure module is merely in contact with the display field of the respective display device and/or is arranged on this display field. Generally, each display field is assigned a surface of the cover plate, wherein the surface of the cover plate is delimited by at least one line, wherein the at least one section of the outer periphery of the visible frame of the respective display device, which encloses the display field thereof, and the at least one line of the cover plate are mutually parallel. In an embodiment of the method with the introduced display system, it is thus possible to completely project the display content of the display field of the respective display device onto the surface of the cover plate which is assigned thereto.
Using a light-guide structure module of a respective display field or display device, the display content thereof is enlarged, wherein a resulting enlarged display content extends, with respect to a size or surface area, beyond a mechanically fixed size or surface area of the display field.
The method is used to seamlessly compose a plurality of display contents of a plurality of smaller display fields of respective display devices to form an enlarged common display field.
