Description

AUDI AG P21351 patent application display device for outputting a pixel-based display content, support element for the display device and motor vehicle with the

display device

DESCRIPTION:

The invention relates to a display device for outputting pixel-based display content. For this purpose, the display device has a display film and a flexible carrier element, on which a rear side of the display film rests in order to carry and/or support it. A rolling mechanism is provided for rolling up at least part of the display sheet and the flexible support member. The invention also includes the carrier element as a component for the display device and a motor vehicle with the display device.

In today's motor vehicles, one or more displays (screens) are almost exclusively used to display information. Depending on the driving situation, a different display size is often necessary. This circumstance has been counteracted for a long time by retracting and extending the display. While ever larger displays have recently been used in modern motor vehicles and are thus becoming increasingly central elements of cockpit design, there is an increasing problem of hiding such large displays within the vehicle console when not in use. Current developments in the field of flexible display panels are increasingly allowing the trend away from rigid, linearly moving display elements towards flexible components, which can use the space available in the vehicle console much more flexibly and efficiently. In order to counteract the mentioned installation space situation in the interior, solutions based on flexible display elements are being found more and more frequently, also due to the rapid developments in the field of flexible displays. The small thickness of such displays usually results in the need for a likewise flexible display support for assembly in a superordinate assembly. A flexible display element can be provided by means of what is known as a display film, such as can be implemented on the basis of OLEDs (organic light-emitting diodes), for example.

EP 2283636 B1 shows a protective device for a flexible display device with a display screen with such a display film. The display screen is provided with stiffening elements which are arranged at regular intervals running parallel to a roll axis in order to ensure that the display device can be rolled.

EP 3599503 B1 shows a display device with a flexible substrate of an OLED display and a strength-optimized, rigid rear cover that is provided with reinforcing ribs.

WO 2019/112814 A1 shows a flexible display device with a support structure. The support structure has a stiffening function to limit flexibility along a predefined direction.

The invention is based on the object of storing and supporting a display film in a display device in such a way that both rolling up is possible and sufficient mechanical support of the display film in manual touch operation when configured as a touch screen (touch display) is given.

The object is solved by the subject matter of the independent patent claims. Advantageous embodiments of the invention are described by the dependent patent claims, the following description and the figures. As a solution, the invention includes a display device for outputting a pixel-based display content. The display device has at least the following components:

• said display foil or screen foil for displaying the display content and

• a flexible carrier element on which the back of the display film rests or rests,

• a rolling mechanism for rolling up at least part of the display sheet and the flexible support member about a rolling axis into roll form.

It is provided that the carrier element is designed as a carrier film on which a support structure is formed which protrudes perpendicularly from the carrier film and extends on a side of the carrier film which is remote from the display film. By "carrier film" it is meant that one side of the carrier element is a layer or film, one side of which may be smooth (to lay the display film on) and the other side of which the support structure is formed.

In order to design the carrier element so that it can be rolled flexibly and still offer sufficient rigidity so that the resulting operating force can be absorbed when a finger touches it, it is provided that the support structure has a large number of cells open on one side, each of which extends to its cell bottom through the carrier film and to are delimited on all cell sides by cell walls projecting perpendicularly from the carrier film, the cells sharing a cell wall in pairs and thus forming a honeycomb structure. In other words, the support structure includes the arrangement of the cell walls projecting perpendicularly from the carrier film. The maximum external dimension of the cells preferably results in a diameter that is less than five centimeters, in particular less than two centimeters (measured parallel to the carrier film or to the cell bottom). The depth of the respective cell, ie the height of the cell walls above the carrier foil, is preferably less than two centimeters, in particular less than one centimeter. By adjusting the diameter and depth, a bend radius can be created be set up to which the support element can be bent at most without being damaged or destroyed.

The display film can be designed in a manner known per se as a so-called flexible display or display that can be rolled up, as can be realized on the basis of OLED technology. A synonymous term is "screen foil". In order to roll up the carrier element together with the display film resting on or lying on it, the rolling mechanism can have a roller body, for example a cylindrical body, or the rolling up can be done as a hollow roller, i.e. the carrier element and the display film form the shell of a flea cylinder when rolled up around the roll-up axis. The axis of the cylinder then forms the roll-up axis or bending axis. A bending radius can preferably be in a range from one centimeter to 15 centimeters. The rolling up does not have to be a complete cylinder, it only needs to be formed by the shape of the roll, e.g. a three-quarter cylinder or a half cylinder.

The invention also includes developments that result in additional advantages.

A further development comprises that the carrier element has assembly areas which are free of the support structure (structure-free) and which are designed to be elongate or strip-shaped, with their direction of longitudinal extension being aligned parallel to the roll-up axis. In addition, it is provided that in the case of the carrier element, a respective rigid support rod or carrier rod is formed on the carrier foil in the respective month area and the respective carrier rod has a mounting device with at least one contact point for fastening an electrical and/or mechanical component. In other words, strips or grooves are cut out in the honeycomb structure, which extend parallel to the roll-up axis, ie parallel to the cylinder axis in the case of the roll shape, on the lateral surface. Such a mounting area is thus sunk into the honeycomb structure and does not interfere with the rolling up of the carrier element. Extends in the respective assembly area a rod-shaped carrier (carrier rod), i.e. instead of the honeycomb structure, a solid rod is formed here. A component, such as a cable or a cooling system or a holder or a roller, can be attached to the support rod via the respective contact point. A thickness of the respective support bar is preferably less than or equal to the cell height of the cell walls in the part of the honeycomb structure adjacent to the mounting areas, so that the support bar remains sunk in relation to the height in the honeycomb structure or does not protrude beyond it. In terms of length, the support rods preferably extend from one edge of the support element to the opposite edge of the support element, or a respective end of the support rod has a distance from the respective edge element in a range of three centimeters to 0.5 centimeters. The honeycomb structure can then be continued towards the edge of the carrier element in the remaining area. A respective width of the respective carrier rod (measured along the circumferential direction of the roll form) can be in a range from 0.5 centimeters to 3 centimeters. In particular, the width of the respective carrier bar in relation to the distance between the carrier bars is selected in a ratio of less than 1:3, ie the distance between the carrier bars is at least three times the width of the carrier bars. The result of this is that the rigidity of the (solid) support rods, which is greater than the rigidity of the honeycomb structure, nevertheless ensures that the support element can be rolled up to form a roll.

A further development comprises that the carrier element with the carrier film and the cell walls projecting perpendicularly therefrom and the carrier rods are designed in one piece. In other words, the respective carrier rod is also designed or formed as a rib on the carrier foil. The carrier element can be formed or designed or manufactured, for example, by means of injection molding or 3D molding. The carrier foil, the honeycomb structure and the carrier rods are then contained in the resulting one-piece component. A plastic can be used as the flexible material. Additionally or alternatively, a rubber and/or a silicone can be included. The one-piece design avoids that when rolling up and/or unrolling the Support element, so during the retraction and / or extension of the support element and the display film, a gap can arise between these elements. A further development includes that the respective carrier rod has a cross-sectional profile in which a taper is formed in the area of the side walls and/or which has a smaller width on a carrier base, where the carrier rod merges into the carrier film, than on an opposite carrier side (on which the at least one contact point can be arranged). In other words, the respective carrier bar is T-shaped or H-shaped or V-shaped in cross-sectional profile (seen perpendicularly to the longitudinal axis of the carrier bar). In other words, a carrier rod can have a T-beam profile. The constricted shape has the advantage that the side walls of the carrier rod, which end on the carrier film of the carrier element, are not perpendicular to the carrier film, but have a curved, concave shape and can therefore give way or flexibly deform when rolled up to form a roll. By choosing the width of the narrower carrier base (carrier base that stands on the carrier film), it is possible to prevent an undesirably large local roll-up radius from forming during roll-up (in relation to the adjacent honeycomb structure).

A further development includes that the cells are designed as rectangular honeycombs and in this case two of the cell walls are aligned along an axial direction parallel to the roll-up axis and the other two cell walls are aligned along a circumferential direction of the roll shape, with a longitudinal extension direction of the rectangular honeycomb being aligned parallel to the roll-up axis. In other words, the honeycombs are designed as elongated rectangles whose length is greater than their width (regardless of the height perpendicular to the carrier film). The honeycombs are formed oblong and with their direction of longitudinal extent parallel to the roll-up axis, ie the longer cell walls are only bent laterally transversely to the wall surface when rolled up, but the wall surface does not have to be compressed. Only the shorter cell walls that extend in the circumferential direction of the roll form must be upset. The wall thickness of the shorter cell walls is preferably also thinner or less than the wall thickness of the longer cell walls. In this arrangement, the carrier element can be deformed into a roll shape with little deformation effort. At the same time, the backing member provides reliable structural reinforcement against operating force acting on the backing sheet when the backing member is unrolled flat.

A further development includes that the cells of the honeycomb structure are arranged in rows of cells which run or are arranged parallel to the roll-up axis. The cell walls of those cells that extend perpendicularly to the roll-up axis, ie the transverse cell walls or those cell walls whose surface normal is aligned parallel to the roll-up axis, are arranged offset to one another in adjacent rows of cells. In other words, only the cell walls that extend parallel to the roll-up axis in the longitudinal extent of the cells form continuous cell walls that extend or run along a plurality of individual cells. In contrast, the cell walls running transversely or perpendicularly thereto are offset from one another in this way

A further development comprises that different cell groups of cells are formed in the honeycomb structure, which are characterized by at least one different cell dimension in relation to a cell wall height and/or an aspect ratio of a cell length (measured parallel to the roll-up axis) and a cell width perpendicular to the roll-up axis (measured parallel to the carrier film, i.e. to the cell bottom) and/or differ in cell length and/or cell width. In other words, by adjusting the different cell dimensions, a height profile and/or a location-dependent rigidity can be adjusted by means of the honeycomb structure in the carrier element.

A development includes that a cell wall thickness of the cell walls, which extend parallel to the roll-up axis, is greater than a cell wall thickness of the cell walls extending perpendicular to the roll-up axis. In this way, the cell walls, which are arranged or extend parallel to the roll-up axis, can be used to adjust the rigidity of the carrier element, while the thinner cell walls can be folded or buckled or compressed perpendicularly thereto when the carrier element is rolled up or rolled up.

As a further solution, the invention comprises a carrier element for an embodiment of the display device according to the invention. The carrier element is made from at least one flexible material in the manner described and is designed as a carrier film on which a support structure is formed which protrudes perpendicularly from the carrier film, the support structure having a multiplicity of cells which are open on one side and which extend through the carrier film towards the cell bottom and are delimited on all cell sides by cell walls projecting perpendicularly from the carrier film, the cells sharing a cell wall in pairs and thus forming a honeycomb structure. In the manner described, the carrier element can be used in a display device as a carrier for a display film. The carrier element together with the display film arranged on it on the carrier film can be unrolled for operation and arranged so as to protrude into a room, while in a stowed position at least part of the carrier element can then be rolled up into a roll form, for example into a Quarter cylinder, or a half cylinder, or a three quarter cylinder, or a full cylinder, to name just a few.

The invention also includes developments of the carrier element according to the invention, which have features that have already been described in connection with the developments of the display device according to the invention. For this reason, the corresponding developments of the carrier element according to the invention are not described again here.

As a further solution, the invention includes a motor vehicle with an embodiment of the display device according to the invention. The The motor vehicle according to the invention is preferably designed as a motor vehicle, in particular as a passenger car or truck, or as a passenger bus or motorcycle. In the motor vehicle, the display device can be installed in an operated console, into which part of the display film and the carrier element can then be rolled up if the entire display area of the display film is not required in the current display mode. In the motor vehicle, for example, the rolling mechanism can be arranged in its control panel or dashboard, which can at least partially roll up the carrier element with the display film arranged thereon inside the control panel, so that the carrier element with the display film assumes the roll shape. If the display film is then to be extended in the display device, the carrier element with the display film arranged thereon can be unrolled and the display surface of the display device can thus be extended or projecting into the interior of the motor vehicle, for example through a slot in the operating console. A planar display surface is then presented to the viewer by means of the display foil, which is held or supported by the carrier element.

The invention also includes the combinations of features of the described embodiments. The invention also includes implementations that each have a combination of the features of several of the described embodiments, unless the embodiments were described as mutually exclusive.

In the exemplary embodiments, the described components of the embodiments each represent individual features of the invention that are to be considered independently of one another and that each also develop the invention independently of one another. Therefore, the disclosure is also intended to encompass combinations of the features of the embodiments other than those illustrated. Furthermore, the described embodiments can also be supplemented by further features of the invention that have already been described.

In the figures, the same reference symbols designate elements with the same function.

Fig. 1 shows a carrier element 10, on the back 11 (in the view of Fig. 1) a flexible display film can be arranged. The carrier element 10 can be part of a display device or can be provided as a component for such a display device. The carrier element 10 can have a honeycomb structure 12, through which a rigidity of the io with low material costs and weight Support element 10 can be achieved for an operating force 13 acting on the rear side 11 . In addition, on the other hand, the carrier element 10 can be rolled up about a bending axis or roll-up axis 14 .

A material of the carrier element 10 can be designed to be flexible or soft for the rolling up, for example based on a plastic and/or a silicone and/or a rubber. Tabs 15 can be formed on the carrier element 10, on which an additional plate 16 can be arranged on the back 11 for expanding a display area of the display film. A fastening device 18 can be provided on an opposite edge 17, for example in the form of a further strap, in order to fasten a rolling mechanism for rolling up the carrier element 10 about the rolling-up axis 14.

FIG. 2 illustrates the honeycomb structure 12 of the embodiment of FIG. 1. It is shown how the rear side 11 of the carrier element 10 can be configured as a carrier film 19 on which the display film 20 can be arranged. The carrier foil 19 represents a cell bottom 22 for individual cells 21 of the honeycomb structure 12. For the sake of clarity, only a few cells 21 are provided with a reference number. Starting from the carrier film 19, cell walls 23 protruding perpendicularly from the carrier film 19 in the case of the carrier element 12 can be formed. The cells 21 are open on one side, ie the cells 21 are delimited by the cell walls 23 and the cell bottom 22 and the cells 21 are only open towards the illustrated front side 24 of the honeycomb structure 12 . The cells 21 are elongate and rectangular, with a direction of longitudinal extent 25 being aligned parallel to the roll-up axis 14 . The cell walls 23, which are aligned parallel to the roll-up axis 14 and define the direction of longitudinal extension 25, are preferably provided with a thicker wall thickness than cell walls 26, which are aligned perpendicular thereto. The height of the cell walls 23, 26 results in a cell depth or cell height H of the cells 21. Cell groups B can be formed, the cells 21 of which differ in their different dimensions. 3 illustrates how mounting strips 27 can be designed in the area of the honeycomb structure, in which support rods 28 can be formed instead of the honeycomb structure 12 . The support rods 28 can each have contact points 29, on which additional components can be arranged or fastened on the front side 24 of the support element 10, for example by means of a screw connection.

4 illustrates how the support rods 28 can each have side walls 30 which are concavely bent and thereby have a taper 31 in a cross-sectional profile seen perpendicularly to the roll-up axis 14 . The overall result is a T-profile or H-profile in this cross section.

4 further illustrates how a flea profile P can be formed by means of the honeycomb structure 12 by means of different cell depths or cell heights of the cell walls 23, 26.

FIG. 5 illustrates how a display device 33 with an embodiment of the carrier element 10 can be provided in a motor vehicle 32 . A control panel 34 and a windshield or windshield 35 of the motor vehicle 32 are shown in a cross section. A roller mechanism 37 can be provided in an interior space 36 of the operating console 34, to which the carrier element 10 can be attached. Shown is how the display film 20 can be held on the back 11 and on the plate 16 . For example, the display film 20 can be glued on. In the case of the display device 33, the display film 20 can be moved out of the interior 36 and into the interior 36 through a shaft 38 of the operating console 34, as is known per se from the prior art. It can be provided that in the retracted state the display film 20 in the area of the plate 16 continues to protrude out of the shaft 38 into an interior 39 of the motor vehicle 32 or remains extended. In the retracted or rolled-up state, as shown in FIG. 5, at least a part of the carrier element 10 with the display film 20 arranged thereon can form one Roll form 40 be rolled up. For example, guide rails 41 can be provided, along which the carrier element 10 can be moved by means of the rolling mechanism 37 . You can do this on the support rods

28 can be attached as components 42 to the contact points 29 legs 43, for example screwed on, and a wheel 44 can be rotatably mounted on each leg 43, which wheel can roll on a rear side 45 of the guide rails 41 and thereby the carrier element 10 on the respective Guide rail 41 holds, so that the carrier element 10 with the display film 20 arranged thereon follows the curved course or the curved shape of the guide rails 41 . The rolling mechanism 37 can have an electric motor 50 which can cause an arm element 51 to rotate 52 , by means of which the carrier element 10 can be pushed out of the shaft 38 along the guide rails 41 or pulled into the shaft 38 .

Fig. 6 shows a perspective view of a possible extended state of the carrier element 10 with the display film 20 arranged thereon. A display surface 60 formed by the display film 20 is shown, on which a control circuit 61 is activated by driving pixels of a pixel matrix of the display -Foil 20 can display at least one control panel 62 on display surface 60, when it is operated or touched or pressed with a finger 63 of a user, control circuit 61 triggers a vehicle function, for example the playback of media content (music and/or video) and/or the Activating or switching lighting and/or setting a driving mode can be controlled or set.

By means of the carrier element, an optimized bending curve for the display film in the rolled-up state (FIG. 5) and sufficient rigidity in the extended state (FIG. 6) can be achieved.

In special applications, there are several contact points for the assembly of further functional components 42 on the display carrier (carrier element).

29 advantageous. These can be placed in the support bars for reliable Power transmission are designed to be sufficiently robust, which does not limit the required flexibility of the display carrier in places.

With the touch operation of a display film mounted on the display carrier, the acting operating force 13 can now be distributed and diverted. The honeycomb structure shown in FIGS. 3 and 4 offers a sufficient possibility for such a distribution of acting forces. For this purpose, the honeycomb structure shown in FIGS. 3 and 4 is interrupted at defined points in such a way that reinforcing ribs can be introduced without negatively influencing the previous bending behavior.

The introduced reinforcing ribs are only repeated in a direction that is at right angles to the desired bending axis. The geometry of the introduced reinforcing ribs or support rods and their distance from one another is designed in such a way that the superordinate bending structure and the resulting global bending radius are influenced as little as possible.

Fig. 1 shows the basic, uninterrupted honeycomb structure without the possibility of installing further functional elements, Fig. 3 shows the modified honeycomb structure with regular reinforcing ribs/support rods, Fig. 2 shows a detailed view of the uninterrupted honeycomb structure, Fig. 4 shows a detailed view of the honeycomb structure with regular stiffening elements in the form of the reinforcing ribs / support bars.

Here are the main differences of the idea:

- it is a support structure in the form of a support element that is in one piece,

- the support structure serves to accommodate a flexible display foil,

- the flexibility is created by using a non-continuous honeycomb structure,

- the honeycomb structure is not homogeneous, but there are profile areas with different flea, width and aspect ratios - the honeycomb structure is interrupted by mounting areas with little or no flexibility,

- these non-flexible assembly areas serve as receptacles for other components as assembly parts, - the ratio of flexible honeycombs / cells to less flexible ones

Support rods is selected in such a way that the local radii occurring due to the less flexible support rods are larger than the minimum permissible values of the flexible display film. Overall, the examples show how a display support for a flexible display and an extension of a flexible support element for the assembly of additional functional elements or components can be provided.
