Description

[0001] The invention relates to a method for providing a display system and a display system.

[0002] Publication US 2020 / 269698 A1 shows a display device on the instrument panel of a vehicle.

[0003] A vehicle display device with a curved cover glass is known from US Patent 2024 / 246416 A1.

[0004] Against this background, the task was to provide a suitable display system for a vehicle.

[0005] This problem is solved by a method and a display system with the features of the independent claims. Embodiments of the method and the display system are described in the dependent claims and the description.

[0006] The method according to the invention is intended for providing a display system for a vehicle, e.g., a motor vehicle. Two convertible top parts are cut and / or cut from a blank, wherein a first cutting contour is cut along one cut for a first convertible top part and a second cutting contour is cut simultaneously and / or synchronously for a second convertible top part, the two cutting contours being opposite to each other, fitting together, and / or complementary. Furthermore, the first convertible top part cut from the blank is arranged on and / or at a first position on an outer wall of a component in an interior space of the vehicle and is designed and / or provided for at least one first display field.It is further provided that the second cover part cut from the blank is arranged on and / or at a second position on the outer wall of the component and is designed and / or provided for at least one second display field, wherein the positions for the two cover parts on the outer wall are spatially distributed and separated from each other.

[0007] In this embodiment, the two convertible top parts are cut from a blank made of a transparent material, such as glass or plastic, which can also be referred to as the master glass. These parts are immediately adjacent before cutting. Along one cut, a cutting tool creates the first cutting contour (e.g., a first curved cutting edge) for the first convertible top part and simultaneously creates the second cutting contour (e.g., a second curved cutting edge) for the second convertible top part. The cutting tool can be mechanical, such as a knife or a saw. It is also possible for the cutting tool to be a laser device that generates a laser beam. The cutting tool cuts the blank along the cutting contours, thereby separating the two convertible top parts.

[0008] In this design, several display fields are spatially distributed and arranged separately from each other on, on and / or in the outer wall of the vehicle component.

[0009] Furthermore, the first convertible top section is arranged on at least one first display field in and / or on the component, wherein the at least one first display field is covered by the first convertible top section. Alternatively or additionally, the first convertible top section is designed as the at least one first display field, being arranged directly on the component. It is possible that the first convertible top section covers at least one primary first display field in sections and is simultaneously designed as at least one secondary first display field.

[0010] Furthermore, the second convertible top section is arranged on at least one second display field in and / or on the component, with the second convertible top section covering this second display field. Alternatively or additionally, the second convertible top section is designed as the second display field and is arranged directly on the component. It is possible that the second convertible top section covers at least one primary second display field in sections and is simultaneously designed as at least one secondary second display field.

[0011] It is also possible that at least one convertible top section, designed as a display field, is arranged on or within another display field on and / or within the component, with the two display fields arranged one above the other, e.g., layered. When such an embodiment of the display system is in operation, the display field arranged within the component can illuminate the convertible top section arranged on it, which is also designed as a display field. Both of these display fields can simultaneously display different content. Depending on the displayed content, the display field, which also functions as a convertible top section, can be switched to be transparent, partially transparent, opaque, or completely opaque.

[0012] When cutting the two convertible top parts from the blank, which is usually made of glass, each cutting contour is provided with at least one section, i.e., a continuously connected section or several interconnected continuous sections, whereby the at least one section of each cutting contour is bent and / or cut straight. Furthermore, the two convertible top parts to be cut from the blank are separated from each other. The cutting contours of both convertible top parts are cut synchronously during the separation process. Each convertible top part can be designed and / or designated as a convertible top glass panel.

[0013] In this design, for the two curved cutting contours of the convertible top glass, a section of a curved line, usually a section of a circle, is formed during cutting. This section can also be designed and / or described as a circular arc. The first cutting contour for the first convertible top section is convex, representing a section of the curve (e.g., the circular arc), and the second cutting contour for the second convertible top section is concave, representing a complementary section of the curve.

[0014] In this embodiment, the first convertible top section is positioned on at least one first display field behind the vehicle's steering wheel, which is to be arranged in the component, and the second convertible top section is positioned on at least one second display field next to the steering wheel. If the cut contours of both convertible top sections are arc-shaped, the first convex cut contour of the first convertible top section is positioned congruently behind the steering wheel rim. The second concave cut contour of the second convertible top section is positioned congruently next to the steering wheel rim.

[0015] In one design, a rectangular blank is used to cut the two convertible top parts, with the parts being cut from this blank and the blank being completely used up. Alternatively, several smaller rectangular blanks can first be cut from a larger one, with each smaller blank then used to cut the convertible top parts.

[0016] The display system according to the invention is designed for a vehicle, wherein the display system is generally manufactured, is manufactured, and / or has been manufactured by an embodiment of the method described above. The display system comprises several spatially distributed, separate display fields in an outer wall of a vehicle component and two convertible top parts. It is provided that the two convertible top parts are cut, are manufactured, and / or have been cut from a single blank, wherein the two convertible top parts are initially directly adjacent to each other in the blank to be cut. Along a cut that separates the convertible top parts, a first cutting contour is provided and / or cut for a first convertible top part and a second cutting contour for a second convertible top part, e.g.cut from the blank, wherein the two cutting contours provided when cutting the blank are opposite to each other, fitting together and / or complementary and / or cut.

[0017] In this display system, each cut contour has at least one curved section and / or at least one straight section, typically k curved and / or m straight sections, where k and m are integers equal to or greater than zero. Both cut contours can be curved or straight section by section. In one embodiment, each cut contour has at least one curved section (i.e., only one curved section, or k > 1, or multiple curved sections) and no straight section. Alternatively, each cut contour has no curved section and at least one straight section (i.e., only one straight section, or m > 1, or multiple straight sections), where the cut contour is angular.If both cutting contours each have at least two sections, i.e., k curved and / or m straight sections, then immediately adjacent sections transition continuously or discontinuously into each other, where k and m are greater than or equal to 1.

[0018] In the design of the display system, at least one of the two cover sections is configured as at least one display field below the at least two display fields and can be arranged directly on the component. Alternatively or additionally, the at least one of the two cover sections can be arranged on at least one display field below the at least two display fields in, on, and / or on the outer wall of the component, covering the respective display field already arranged in and / or on the component.

[0019] The typically transparent blank and the typically transparent convertible top parts cut from it, e.g., cover lenses, can be planar or curved, bent, and / or convex. The convertible top parts for display fields of an instrument cluster or a center display are cut and / or manufactured from the same blank or mother glass and, due to the intended cut contours, have an optimized trim relative to each other and a maximum visible area for the display system.

[0020] The master glass or blank, and thus the convertible top panels cut from it, can be transparent and, in a possible configuration, incorporate optical light sources such as organic light-emitting diodes (OLEDs), micro-light-emitting diodes (µLEDs), or plastic OLEDs (POLEDs or P-OLEDs) as display fields. Alternatively or additionally, the blank and the convertible top panels can be touch-sensitive and designed and / or referred to as touch displays. This process opens up new design possibilities for a display system that can be very compact and allows for a generic and intuitive arrangement within the vehicle.

[0021] In this display system, several separate display fields or cells, for example two, are covered by the two convertible top sections cut from the blank. Cutting the convertible top sections from the blank results in very little waste. The blank to be cut in this process can be optimized for a television panel. By selecting and designing the cutting contours, even free-form areas of the component, such as partially curved sections, and the display fields located within them can be covered. When designing the cutting contours or outlines for the convertible top sections, aesthetics, ergonomics, user-friendliness, and / or visibility can be taken into account, ensuring that the display fields covered by the convertible top sections are as fully visible as possible to each occupant of the vehicle, such as the driver. Due to the minimal waste, manufacturing costs can be reduced.

[0022] It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or on their own, without leaving the scope of the present invention.

[0023] The invention is schematically illustrated with reference to embodiments in the drawing and is described schematically and in detail with reference to the drawing.

[0024] Fig. 1a, Fig. 1b, Fig. 1c, Fig. Figure 1d shows a schematic representation of a first embodiment of the display system according to the invention, which is produced when carrying out a first embodiment of the method according to the invention.

[0025] Fig. 2a, Fig. 2b, Fig. 2c, Fig. 2d, Fig. Figure 2e shows in schematic representation further embodiments of the display system according to the invention, which are produced by carrying out further embodiments of the method according to the invention.

[0026] The figures are described in a coherent and comprehensive manner. The same reference symbols are assigned to the same components.

[0027] Fig. Figure 1a shows a schematic representation of a flat rectangular primary blank 2 made of transparent material, which serves as the starting part for manufacturing the two components in Fig. Figure 1b shows the convertible top parts 4, 6 of the display system according to the invention being used in the first embodiment of the method according to the invention. A cutting tool is used to cut a first cutting contour 8 for a first convertible top part 4 and simultaneously a second cutting contour 10 for a second convertible top part 6, wherein the two cutting contours 8, 10 are cut opposite to each other and / or complementary. The first cutting contour 8 for the first convertible top part 4 is convex and the second cutting contour 10 for the second convertible top part 6 is concave.

[0028] The first convertible top part 4 has a first rectangular section and an adjoining circular segment bounded by the first cutting contour 8, wherein the first convertible top part 4 is bounded by three straight outer edges and the convex first cutting contour 8. The second convertible top part 6 has a second rectangular section from which the circular segment is cut, wherein the second section is recessed along the second cutting contour 10, wherein the second convertible top part 6 is bounded by three outer edges and the concave second cutting contour 10.

[0029] How Fig. As shown in Figure 1c, the two convertible top sections 4 and 6 are used to cover two display fields 5 and 7 in a component for the interior of a vehicle, in this case a motor vehicle. The second display field 7 is located next to the steering wheel 12 and is designed here as a central display. The first display field 5 is arranged on, attached to, and / or in the component in front of the front seats of the vehicle, with a steering wheel 12 also being rotatably mounted on the component, usually via a steering column. The first display field 5 is located here in an instrument cluster behind the steering wheel 12.

[0030] The first convex circular arc-shaped cutting contour 8 of the first convertible top part 4 is adapted to a rim contour of a steering wheel rim 12 and positioned and / or arranged on the component. The first convex cutting contour 8 is shown in the illustration. Fig. 1b When the procedure is carried out, the first part of the convertible top 4 is rotated 90° counterclockwise and is or will be slightly offset downwards from the perspective of a driver in a driver's seat of the vehicle relative to the rim contour or the steering rim.

[0031] In this embodiment, the steering wheel 12's rim has a steering wheel radius. For the first arc-shaped cutting contour 8, or for a corresponding segment of a circle, a cutting contour radius is set and / or provided when cutting the first cutting contour 8, which is adapted to the steering wheel rim radius. A value corresponding to the steering wheel rim radius can be set for the cutting contour radius. When arranging the first convertible top section 4 on the component, the center point of the segment of the circle, and thus of a circular arc, that describes the first cutting contour 8, can be positioned above or below the steering wheel 12's axis of rotation or a vertical axis of the vehicle. If the cutting contour radius and the steering wheel rim radius are the same, the center point of the circular arc of the first cutting contour 8 can also be positioned below the center point of the steering wheel rim.It is also possible to set a smaller value for the cutting contour radius than for the steering rim radius, in which case the center point of the first cutting contour 8 is located above the center point of the steering rim.

[0032] The second concave circular arc-shaped cutting contour 10 of the second convertible top part 6 is also adapted to a rim contour of a steering wheel rim of the steering wheel 12 and positioned and / or arranged on the component, wherein the second cutting contour 10 is slightly offset laterally, i.e. to the right or left, from the perspective of a driver in a driver's seat of the vehicle relative to the rim contour or the steering wheel rim.

[0033] In one embodiment, the center point of the section of the circle, and thus of a circular arc describing the second cutting contour 10, can be positioned on the axis of rotation of the steering wheel 12 or on a horizontal transverse axis of the vehicle to the right or left of the axis of rotation when the second convertible top section 6 is placed on the component. If the radius of the cutting contour and the radius of the steering wheel rim are the same, the center point of the circular arc of the second cutting contour 10 can also be positioned next to the center point of the steering wheel rim.

[0034] The cutting contours 8, 10 of the two convertible top parts 4, 6 are oriented and / or aligned when placed on the component with a shadow of the steering wheel 12 on the instrument cluster and the central display, whereby the driver can see the convex circular segment with the first cutting contour 8 on the first convertible top part 4 or a corresponding semicircle as completely as possible without shadow formation.
