Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is based upon and claims the benefit of prior German Patent Application No. DE 10 2016 200 355.0, filed on Jan. 14, 2016, the entire contents of which are incorporated herein by reference. 
       TECHNICAL FIELD 
       [0002]    The present disclosure relates to an interior design element for a motor vehicle, comprising a display surface formed partly by a screen element and partly by a perforated section within a decor layer. The present disclosure also relates to a method for displaying image information on an interior design element. 
       BACKGROUND 
       [0003]    Automobile interiors are increasingly using display screens. Screens in a vehicle may display information specific to the vehicle. They may also be used as universal display devices with which other content, such as navigation and entertainment content, can be displayed individually in addition to vehicle-specific parameters and information. However, prior art screens suffer various disadvantages and drawbacks. For example, the screens stand out noticeably from the interior design element due to their rectangular shape and their generally shiny, glaring surface, limiting their potential for integration into the vehicle design. 
         [0004]    Partly covering the screen is known in the state of the art. However, one problem with the prior art is that the surface of the screen is then no longer fully available for displaying information. 
         [0005]    For example, in FR 3 016 145 A1 a screen is described that has a visible area and a partly covered area. The visible area provides information for the driver. The partly covered area serves as indirect lighting. For this purpose the partly covered area has a diffusing disk at a light passage orifice through which light irradiated from the screen exits into the passenger space. 
         [0006]    Furthermore, DE 10 2008 037 977 A1 discloses a display device for a vehicle with a display that is or can be mounted in the interior of the vehicle. The display device includes a lighting unit with which the area surrounding the display can be illuminated and a control device to control the illumination generated by the lighting unit. 
         [0007]    However, disadvantages of the display device include that information can only be shown via the screen of the display device. The lighting unit merely serves to make it easier for the passenger to recognize the information shown on the screen. 
       SUMMARY 
       [0008]    Embodiments of the present disclosure provide an interior design element with a screen, which offers enhanced possibilities for integration of the screen into the interior design element. 
         [0009]    Embodiments of the present disclosure provide an interior design element according to the present disclosure for a motor vehicle comprising a carrier, a screen element, a decor layer with one or more perforated sections, at least one lighting element and a control unit coupled to the screen element and to the lighting element. The lighting element may be a first lighting element. The screen element and the decor layer are arranged on the carrier, and the perforated section of the decor layer borders the screen element. 
         [0010]    According to embodiments of the present disclosure, both the screen element and the decor layer are arranged on a shared side of the carrier, for example in a common plane. Specifically, this side can be the side of the carrier that faces the interior of the motor vehicle. The decor layer can be non-transparent, transparent or semitransparent. For example, the decor layer can be made of leather, synthetic leather, a textile or a plastic foil. The screen element may be provided as a flat screen. In addition, the decor layer can embodied to border not only one side, but also several sides of the screen element. Thus, where applicable, it can also frame the screen element. 
         [0011]    According to embodiments of the present disclosure, the perforated section in the decor layer can be formed by a plurality of holes. The holes may be dead-end holes or through-holes, for example. The holes can be added later to the decor layer. This can be done with techniques such as lasers, by punching, or stamping. However, the perforated section can also include pre-existing holes formed by the nature of the decor layer. For example, if a textile fabric is used for the decor layer, the holes in the perforated section could also be formed by interstices between the threads of the fabric. With the perforated section at least one area is created in the decor layer in which visible light can shine through the decor layer. 
         [0012]    According to embodiments of the present disclosure, the perforated section is penetrable by light from the first lighting element. Therefore, the first lighting element is preferably arranged to permit the light emitted from the first lighting element to radiate toward the perforated section. The first lighting element can be arranged for this purpose directly in the perforated section on the decor layer. 
         [0013]    According to embodiments of the present disclosure, the perforated section, which borders the screen element, serves primarily to enable a common display surface to be formed by the screen element and the perforated section. Thus, a portion of the display surface is directly formed by the screen element, and an additional portion of the display surface is formed by the perforated section, since light from the first lighting element can shine through it. To create the shared display surface the control unit subdivides image information to be shown on the display surface into a first information portion and a second information portion, and activates the lighting element and the screen element such that the first information portion can be displayed in the perforated section and the second information portion in the screen element. The information portions in the perforated section and in the screen element complement each other and, in total, represent the complete image information. Particularly in the perforated section, the first information portion can be depicted in the form of light signals by the first lighting element. The light signals then shine through the perforated section and become visible as the corresponding first information portion on the perforated section. On activating the first lighting element, the control unit can take a correction factor into consideration, with the aid of which, for example, the influence that the holes in the perforated section have on the first information portion or its light signals can be corrected. 
         [0014]    According to embodiments of the present disclosure, the control unit can activate the first lighting element and the screen element to display image information in the perforated section only, in the screen element only, or partly in the screen element and partly in the perforated section. 
         [0015]    Embodiments of the present disclosure provide an interior design element for a motor vehicle, comprising a carrier; a screen element arranged on the carrier; a decor layer arranged on the carrier having a perforated section, the perforated section bordering the screen element and forming a common display surface with the screen element; a lighting element arranged beneath the perforated section and configured to emit light through the perforated section; and a control unit coupled to the screen element and the lighting element, wherein the control unit is configured to divide image information into a first information portion and a second information portion; and activate the lighting element and the screen element to display the first information portion in the perforated section and display the second information portion in the screen element, wherein the displayed first and second information portions complement each other and together represent the image information. 
         [0016]    According to embodiments of the present disclosure, the image information can be stored in a storage device before it is divided. After the image information has been divided into information portions by the control unit, these information portions can be deposited either on a shared storage device or on separate storage devices. If the information portions are deposited on separate storage devices, the information portion that is earmarked for display on the screen element may be stored on a first separate storage device and the information that is intended for display in the perforated area is stored in a second separate storage device. The image information or the information portions can be loaded from the storage devices by the control unit. 
         [0017]    According to embodiments of the present disclosure, the term “image information” refers to that portion of knowledge that the viewer of the display surface can visually perceive. For example, the image information or information portions can be generated on the display surface through one or more luminous areas which, for instance, are highlighted by one or more light colors and/or at least one light intensity and/or a defined contour on the display surface. Thus, this does not merely entail a simple illumination that the viewer can perceive. Rather, the viewer may combine that which is visually perceived with a certain knowledge or acquires that knowledge by observing the luminous areas. The luminous areas in the perforated section in particular can be partitioned by the decor layer into luminous subareas. The image information can be presented by physical data which provides the vehicle occupants with information relevant to the vehicle or to the route, such as the course of the road or speed limits. 
         [0018]    According to embodiments of the present disclosure, a display surface is extended into the decor of the interior design element. The display surface may enhance the possibilities for integration of the screen element, and provide a smooth transition between decor and screen element. 
         [0019]    According to embodiments of the present disclosure, to further increase the functionality of the interior design element, a touch-sensitive touch panel at least by sections on the display surface is provided. This touch panel is coupled to the control unit such that when the display surface is touched, a touch location and/or a direction of movement of a dynamic touch on the display surface, particularly including the area inside the perforated section, can be detected by the control unit with the aid of the touch panel. Thus , the touch panel may extend not only across the screen element, but also across the perforated section. To this end, the touch panel can be embodied to extend across the screen element and the perforated section. 
         [0020]    According to embodiments of the present disclosure, the touch panel includes two or more tactile elements. The first tactile element may be arranged on the perforated section while the second tactile element may be arranged on the screen element, with both tactile elements together forming the touch panel. 
         [0021]    According to embodiments of the present disclosure, an input field can be created using the touch panel. As a result, not only can image information be output with the aid of the display surface, but the viewer can also interact with the image information. 
         [0022]    According to embodiments of the present disclosure, the control unit matches the touch location or direction of movement of a dynamic touch with a position of the image information on the display surface. This enables the control unit to detect when an item of image information has been touched, for example. This gives the viewer the opportunity to interact with the displayed image information. For example, if the image information displayed is a control element and the control unit detects a touch at a touch location corresponding to the position of the control element on the display surface, the control unit can recognize that the viewer wishes to operate the control element shown. The corresponding operation to be performed can be conducted either by the control unit itself or, as alternatively, a signal can be transmitted by the control unit to the board electronics, indicating that a corresponding control element has been activated. 
         [0023]    According to embodiments of the present disclosure, in the perforated section the touch panel can be located either on the decor layer, i.e. on a side of the decor layer facing the interior space, or between the carrier and the decor layer. As an alternative, the touch panel can also be located on a side of the carrier facing away from the decor layer. In addition, the touch panel can be located on the screen element, i.e. facing the interior space, or between the screen element and the carrier. Here, too, it is contemplated that the touch panel may be located on a side of the carrier facing away from the screen element. 
         [0024]    According to embodiments of the present disclosure, the touch panel can include a piezoelectric or capacitive sensor element. Both capacitive and piezoelectric sensor elements, due to their availability in small sizes, may enable the required installation space of the touch panel to increase only slightly. At the same time, a capacitive sensor element in particular may allow a user to interact with the screen without necessarily having to touch the display surface. It may be sufficient here for the user to hold a finger very close to the display surface. Accordingly, a capacitive sensor element may be used particularly if the touch panel is arranged on a side of the carrier that faces away from the screen element and the perforated section. Although in this case the viewer does not actually touch the touch panel itself, the corresponding touch on the display surface can still be detected. 
         [0025]    According to embodiments of the present disclosure, the touch panel includes a special transparent foil. Since piezoelectric and capacitive sensor elements in particular can be provided in a virtually transparent form, a transparent foil may serve as the substrate for these sensor elements and the touch panel may include a transparent foil of this type. This may simplify handling of the touch panel. Further, the image information shown in the perforated section and in the screen element is not affected or distorted by the touch panel, insofar as the touch panel is located on the perforated section and/or the screen element. 
         [0026]    According to embodiments of the present disclosure, the first lighting element has several points of light that can be controlled individually by the control unit in order for the first information portion to be depicted in the perforated section. The number of light points can correspond to the number of perforations. For instance, it is contemplated to have one light point on the first lighting element for each perforation hole provided. However, it is also contemplated for one perforation hole to have several light points shining through it, with the result that the number of light points is in a defined relationship to the number of holes in the perforated section. This enables the light from several light points in a hole to overlap, making it possible to more precisely adjust the desired color of the light to be perceived by the viewer. 
         [0027]    According to embodiments of the present disclosure, one light point may shine through a plurality of holes in the perforated section. Due to the low number of light points to be activated, the cost of the first lighting unit could be reduced. 
         [0028]    According to embodiments of the present disclosure, the first lighting element may have a lower number of light points than the screen element. Since the first lighting element is covered from the viewer&#39;s perspective by the decor layer, it is possible to select a lower resolution of the display surface in the perforated section than in the screen element. This can lower the cost of the entire arrangement, since a less expensive alternative to a high-resolution screen element can be selected in the perforated section. For example, if a low resolution is desired, the light points can also be provided from punctiform light sources, especially light emitting diodes (LEDs) or organic light emitting diodes (OLEDs). 
         [0029]    According to embodiments of the present disclosure, additional partitions can be provided between the punctiform light sources to divide the first lighting element into sections. With the partitions it is possible to ensure that the light from the light sources does not overlap and that the information portions depicted remain recognizable. 
         [0030]    According to embodiments of the present disclosure, the interior design element can have at least a second lighting element arranged at an angle to the first lighting element and having a direction of emission extending substantially parallel to the decor layer. The second lighting element, for instance, can include an LED or OLED and may have a punctiform or strip-like shape. It may have a maximum light intensity that is lower than the maximum light intensity of the first lighting element, with the result that even when the second lighting element is switched on, the first information portion generated by the first lighting element is still visible. Here, “substantially parallel” is intended to describe an angle of between −15 and +15 degrees that stretches between a plane defined by the decor layer and a main emitting direction of the second lighting element. With the aid of the second lighting element it is possible to backlight the perforated section over a large area. The second lighting element may be arranged adjacent to the perforated section and have a direction of emission extending along the perforated section. 
         [0031]    According to embodiments of the present disclosure, to ensure that the decor layer maintains adequate stability particularly in the perforated section, the carrier may be made of a material that is at least partly transparent and that is arranged between the first lighting element and the decor layer. In this case, the first lighting element can be located on a side of the carrier facing away from the decor layer, and it can radiate through the carrier in the direction of the perforated section. The decor layer in this case is adequately strong and sturdy, and at the same time the desired light penetration through the perforated section can be ensured. 
         [0032]    According to embodiments of the present disclosure, the decor layer has holes in the perforated section with a diameter of 0.01 to 3 mm. Within this range it can be ensured that the holes, insofar as they are not backlit by the first lighting element, are not visible or only barely visible to a viewer. By the same token, however, the holes are large enough in diameter to ensure that in the case of backlighting the image information or the information portions can be recognized. In some embodiments, holes are spaced apart by 0.1 to 3 mm. Moreover, the decor layer can have a thickness of 0.15 to 2 mm. In this way, for example, it is possible to avoid letting perception of the first information portion in the perforated section depend on the viewing angle. 
         [0033]    According to embodiments of the present disclosure, the diameter of the holes decreases as the distance from the screen element increases. This makes it easier to recognize where the boundaries of the display surface are located. The number and/or arrangement of the light points formed by the first lighting element can likewise be adjusted here to the decreasing diameter of the holes. 
         [0034]    According to embodiments of the present disclosure, to ensure that the holes are not soiled by external factors, they can be filled at least partly with a transparent filler material. For example, the holes can be at least partly filled by a foil that is applied to the decor layer at least in sections and becomes partly embedded in the holes. 
         [0035]    Embodiments of the present disclosure also provide a method of operating an interior design element according to the present disclosure in a motor vehicle. The method includes the following steps: 
         [0036]    uploading image information into the control unit; 
         [0037]    dividing up the image information into a first information portion and a second information portion by the control unit; and 
         [0038]    displaying the first information portion in the perforated section and the second information portion in the screen element in that the control unit activates the screen element and the lighting element, wherein the information portions in the perforated section and in the screen element complement each other and in total represent the complete image information. 
         [0039]    According to embodiments of the present disclosure, before or during the step of uploading, the control unit detects an input signal from a touch-sensitive touch panel arranged in the area of the screen element and/or of the perforated section. This can influence the image information to be displayed, both in position and in content, as a function of user input gathered via the touch panel. 
         [0040]    Embodiments of the present disclosure provide a method of operating an interior design element of a motor vehicle, the interior design element comprising a carrier, a screen element arranged on the carrier, a decor layer arranged on the carrier and having a perforated section bordering the screen element and forming a common display surface with the screen element, a lighting element configured to emit light through the perforated section, and a control unit coupled to the screen element and the lighting element, the method comprising the following steps performed by the control unit: receiving image information; dividing the image information into a first information portion and a second information portion; and activating the lighting element and the screen element to display the first information portion in the perforated section and display the second information portion in the screen element, wherein the displayed first and second information portions complement each other and together represent the image information. 
         [0041]    The described properties of the present disclosure and the manner in which these are achieved will be described in more detail based on the following detailed description. The foregoing general description and the following detailed description are exemplary and explanatory only, and are not restrictive of embodiments consistent with the present disclosure. Further, the accompanying drawings illustrate embodiments of the present disclosure, and together with the description, serve to explain principles of the present disclosure.

     DETAILED DESCRIPTION 
       [0048]      FIG. 1  shows a three-dimensional view of a section of an interior design element according to the present disclosure. The interior design element comprises a decor layer  3  and a screen element  2 . The screen element  2  and the decor layer  3  form the visible side of the interior design element, in which the screen element borders the decorative part  3 . In the present embodiment the screen element  2  is a flat-panel display and the decor layer  3  is made of leather. A plurality of holes  10  have been made in the decor layer  3 , thereby forming a perforated section  4 . The perforated section  4  here is positioned to border the screen element  2  and forms a sort of ring around the screen element. Both the screen element  2  and the decor layer  3  are mounted on a carrier (shown in  FIG. 4 ). However, in the present embodiment the carrier has been removed to ensure the clarity of the drawing. The holes may be filled at least partially with a transparent filler material  19  (shown in  FIG. 3 ). 
         [0049]    A first lighting element  5  is located underneath the perforated section  4 . As in the case of the perforated section  4 , the lighting element  5  wraps around the screen element  2 . The first lighting element  5  in the present embodiment is provided as a plurality of punctiform light sources  5 . 1  (i.e. in the shape of a point) arranged on a carrier plate  14 . The punctiform light sources  5 . 1  are RGB LEDs. The RGB LEDs can be activated independently of one another by a control unit (not shown in  FIG. 1 ). Partitions  9  are provided between the punctiform light sources  5 . 1 . The partitions  9  divide the first lighting element  5 . 1  into sections. This can prevent the light emitted from the punctiform light sources  5 . 1  from excessively overlapping before reaching the perforated section  4 . 
         [0050]    In addition, a second lighting element  8  is arranged on the interior design element, substantially at right angles to the decor layer  3 . The second lighting element  8  borders the screen element  2  and radiates parallel to the decor layer  3 , away from the screen element  2  In this manner, a soft illumination of the perforated section  4  over a broad area can be provided with the aid of the second lighting element  8 . To ensure that the broad illumination is not impeded by the partitions  9 , the partitions  9  can have transparent sections, for example, or they can have a height selected to maintain a gap between the partition  9  and the decor layer  3 . 
         [0051]    A control unit (not shown), that is coupled to the first lighting element  5  and to the screen element  2 , controls a display surface  12  composed partly of the perforated section  4  and partly of the screen element  2 . Image information  11  to be displayed is divided by the control unit into a first and a second information portion  11 . 1 ,  11 . 2 . The first information portion  11 . 1  can then be displayed in the perforated section  4  with the aid of the first lighting element  5  and the second information portion  11 . 2  can be displayed in the screen element  2 . 
         [0052]    In this way, for example, a portion of the image information  11  in the perforated section  4  and an additional portion in the screen element  2  may be displayed. An example of this is shown in  FIG. 2 , which depicts a plan view of the embodiment according to the present disclosure as shown in  FIG. 1 . A second information portion  11 . 2 , which a viewer may interpret as a roadmap for navigation, is provided by the screen element  2 . A first information portion  11 . 1  is additionally displayed in the perforated section, representing the continued course of the road into which the vehicle will presumably travel. Furthermore, the course of the road, where applicable, is displayed in a color that differs from that of the normal route. This may indicate to the viewer the current traffic situation, for example, indicating a traffic jam. In the present example, the image information  11  relating to the road is thus displayed not only by the perforated section  4 , but also by the screen element  2 . The decor layer  3  in the perforated section  4  is part of the display surface  12  that is observed by the viewer. The two information portions  11 . 1 ,  11 . 2  displayed together form the image information  11  that is presented to the viewer. The information portions  11 . 1 ,  11 . 2  are shown as luminous areas on the display surface  12 . 
         [0053]      FIG. 3  shows a plan view of the interior design element according to the present disclosure as shown in  FIGS. 1 and 2 , in another section of the display surface  12 . In contrast to  FIG. 2 , in the perforated section  4  additional image information  11  is generated that does not extend into the screen element  2 , and yet there is a connection with the image information  11  in the screen element  2 . For example, in the screen element  2  image information  11  is generated which the viewer interprets as being the letter “C”, while the image information  11  produced in the perforated section  4  is a dynamic running light that signals to the viewer that, for example, the image information  11  “letter C” has been selected. 
         [0054]    As shown in  FIG. 3 , the holes may be filled at least partially with a transparent filler material  19 . This may reduce dirt, debris, or other materials from collecting in the holes. Further, the first and the second information portions  11 . 1 ,  11 . 2  may be generated by one or more luminous areas  15 ,  16  set apart from the display surface  12  by one or more light colors  17 ,  18  and/or at least one light intensity and/or a defined contour. For example, the perforated section  4  may include a first luminous area  15  configured to display the first information portion  11 . 1 , and the screen element  2  may include a second luminous area  16  configured to display the second information portion  11 . 2 . The displayed first and second information portions  11 . 1 ,  11 . 2  may be distinguished from the display surface  12  by at least one of light color, light intensity, or defined contour. 
         [0055]      FIG. 4  shows a cross-section of an interior design element according to the present disclosure. Here a section was selected in which the perforated section is arranged in the decor layer  3 . The carrier  1  is arranged between the first lighting element  5  and the decor layer  3 . The carrier  1  in the present embodiment is made of polycarbonate and is transparent, such that light emitted by the first lighting element  5  can radiate through the carrier  1  and reach the decor layer  3 . Furthermore, a touch panel  6  in the form of a touch-sensitive transparent foil is arranged between the decor layer  3  and the carrier  1 . Capacitive sensor elements are arranged on the foil, registering when a viewer touches the perforated section  4 , for example. These registered movements can be relayed to the control unit (not shown), so that the display surface  12  can be used at the same time as the input field. 
         [0056]      FIG. 5  shows a schematic view of a motor vehicle  20  in the form of an automobile, with an integrated interior design element according to the present disclosure. In the present embodiment a control unit  21  is coupled to a board network  22  of a vehicle  20  via cables, thereby enabling vehicle-specific data to be gathered and processed by the control unit  21 . The interior design element according to the present disclosure possesses two optical sensor elements  23  as an additional operating element in the form of cameras through which passengers&#39; gestures can be detected. The recognized gestures can be transmitted to the control unit and serve as an input signal for creating or modifying image information  11 . 
         [0057]      FIG. 6  shows a flowchart of a method according to the present disclosure for displaying image information  11  in an interior design element of the present disclosure. The method begins with step S 1 , uploading image information  11  to be displayed into the control unit  21 . The image information  11  here can be made available, for example, by an entertainment system or a navigation system connected to the control unit  21 . In addition to the information to be displayed, the image information also includes local parameters with which the control unit  21  can determine the exact position of the image information  11  on the display surface. Step S 2  is performed after step S 1  and encompasses the distribution of the image information  11 . During the distribution, the control unit  21  subdivides the image information  11  into a first and a second information portion  11 . 1 ,  11 . 2 . The first information portion  11 . 1  serves for displaying a portion of the image information  11  in the perforated section  4 , while the second information portion  11 . 2  serves for displaying a portion of the image information  11  in the screen element  2 . The exact distribution depends on where the image information  11  to be generated is intended to be displayed on the display surface and in what proportions the image information  11  is positioned in the perforated section and in the screen element. 
         [0058]    Finally, step S 2  is followed by steps S 3 . 1  and S 3 . 2 , in which step S 3 . 1  includes displaying the first information portion  11 . 1  in the perforated section  4  and S 3 . 2  encompasses displaying the information portion  11 . 2  in the perforated section  4 . The control unit  21  controls the screen element  2  or the lighting element  5  accordingly, in order to display the particular information portion  11 . 1 ,  11 . 2  on the perforated section  4  or the screen element  2 , respectively. Thus, the information portions  11 . 1 ,  11 . 2  are presented separately to the viewer, who may perceive the complete image information  11  through the combination of information portions  11 . 1 ,  11 . 2 .
