DESCRIPTION OF EXAMPLES
[0036] Where the spatial relationship of individual parts of the interior trim part is described in the following, this spatial relationship refers to the installed condition, wherein the front of the interior trim part is the side facing towards the passenger compartment and the rear side is facing away from the passenger compartment. The indication that a first part is located in front of or behind a second part means that the first part is located on the side facing the passenger compartment or on the side of the second part facing away passenger compartment, respectively.
[0037]
[0038]
[0039] The support 12 can be made from plastic or a fibre-reinforced composite material and is used for mounting and aligning at least some or all of the parts of the interior trim part. In the example shown here, it has a cut out or a recess 22 for receiving the electronic module 20, and a bay 24 for receiving the monitor 18. The bay 24 is referred to as such because, from the point of view of the passenger compartment, it forms a cut out in the support 12, so that the monitor 18, if it is arranged on the rear 26 of the bay 24, is set back relative to the front face or front of the support 12. The rear side 26 which is used for mounting the monitor, is oriented at an angle to the surface of the support 12 in such a way that the monitor 18 can be clearly viewed by the driver. The thin-film display 14 is mounted on the front side or front of the support 12. The thin-film display can also be integrated or embedded in the shaped part, or be configured in a sandwich structure with the shaped part.
[0040] The thin-film display 14 can be or comprise, for example, an OLED (organic light-emitting diode), TFT (Thin Film Transistor), LCD (Liquid Crystal) or SED (surface conduction electron emitter) display. The following discussion deals with the example of an OLED display in further detail.
[0041] OLED displays are composed of a plurality of organic layers. An anode layer, consisting for example of indium tin oxide (ITO), is arranged on a support which can be formed of a thin glass or plastic substrate. The support can be flexible. Above the anode layer, a hole transport layer (HTL) is positioned. An organic emitter layer (EL) can be applied to the HTL which either contains dye (5 to 10 to percent) or consists completely of dye. An electron transport layer (ETL) is optionally applied thereon. Finally, a cathode, consisting of a metal or an alloy with low electron work function, such as calcium, aluminium, barium, ruthenium, magnesium-silver alloy, is deposited by evaporation. As a protective layer and to reduce the injection barrier for electrons, a very thin layer of lithium fluoride, caesium fluoride or silver can be deposited between the cathode and ETL.
[0042] One of the features of OLED display screens is the very high contrast, since they can work successfully without backlighting: black pixels emit no light. While LCDs, for example, act as coloured filters and some light still shines through even in the dark state, OLEDs emit coloured light only when activated which also ensures very good colour rendition. This method is efficient which means OLEDs, in particular when displaying dark images, require less energy.
[0043] The thin-film display 14 can be designed in such a way that, by applying a charging voltage to the display, the image area can transition from a transparent state to a translucent state, by a portion, or even all, of the wavelengths of light being blocked. The thin-film display 14 therefore, when it is not activated, is transparent and in or behind the shaped part, is almost visually imperceptible. If it is being activated, in order to display an image on the thin-film display 14, it transfers to the translucent state. The thin-film display 14 is coupled to the electronics module 20 via a connecting cable 30 and is controlled thereby.
[0044] The electronics module 20 can control the thin-film display 14 to display a decorative surface, to display control elements or to display a camera image, for example, the image of a backward-directed camera which replaces or complements a rear-view mirror. The different types of display can be presented alternatively or else simultaneously and, under certain circumstances, can also be superimposed.
[0045] In the example of
[0046] The interior trim part 10 is closed off to the passenger compartment by the shaped part 16. The shaped part 16 can also be fixed to the support 12. In an example it comprises of a single- or multi-layered glass structure. On the side of the shaped part facing the interior of the vehicle, a coating may be applied. This protects the interior trim part 10 against scratches, contamination by dirt, the effect of liquids and the like. The shaped part can also comprise one or a plurality of layers of plastic, e.g. of FR4 (a highly flame-resistant and flame retardant composite material including epoxy resin and fibreglass fabric), PES (polyester) or PC-PMMA (polycarbonate polymethyl-methacrylate) or can be constructed with another thin-film substrate. A printed circuit board or a set of electronics and/or optics applied by other means can be mounted directly on the material of the shaped part and/or be integrated therein. The electronics and/or optics can comprise, for example, LEDs, microchips, sensors and/or display components, such as an OLED display, LCD or ITO thin film display, and touch sensors or proximity sensors. To assemble the electronics, semiconducting and conducting layers and insulators can be deposited on or in the material of the shaped part. Appropriate techniques are known from semiconductor component manufacturing. In the shaped part 16 a pattern 16 can be incorporated, for example for labelling a control element, such as a touch sensor or proximity sensor. At the respective location, a touch sensor or proximity sensor, for example, a capacitive sensor, switch, slider or the like, can be integrated directly into the shaped part. The thin-film display 14 and the shaped part 16 can be glued and/or aligned and fixed relative to each other using the support 12.
[0047] In the example of
[0048] Instead of a monitor a projection system, e.g. a nano-projector or pico-projector, can also be integrated into the interior trim part which projects a camera image onto a side window or the windscreen, for example, in the manner of a head-up display. In this case, a corresponding routing of the light through the interior trim part must be provided. The glass of the window pane or windscreen can then serve as a projection surface, and a transparent electronic display can be integrated into the glass or be mounted thereon. The light source can be provided by light-emitting diodes, and the brightness of the image may be controlled via a photo sensor as a function of the ambient light. The image itself can be generated, for example, by a coloured high-resolution TFT or LCD display.
[0049] The electronics module 20 can drive the monitor 18 or other display device which is integrated in the support 12, such as a head-up display. Further details of the example shown here are explained with reference to
[0050]
[0051] The thin-film display 34 can comprise, as in
[0052] The display region 38 can also be used to display images, including moving images, from any other source, including another camera, a television receiver, a SIM card, a USB stick or flash memory, an app interface, a DVD player and a streaming service.

[0066] A further example of an interior trim part is schematically shown in
[0067] One example of a portion of an interior trim part as shown in
[0068] A control device, such as an electronic module, may be provided and operatively coupled to the thin film display portion 84 and monitor portion 88 but is not shown in the drawings. A gesture, head and/or eye movement detection and tracking device 44 may be located at or behind the shaped part 86 and may be exposed through an opening provided therein. For further details, such as concerning the implementation of the thin film display portion 84 and monitor portion 88, reference is made to the above description of different examples.
[0069] The monitor portion 88 can be used as a camera monitor for displaying the recording of a camera arranged to record images of the vehicle exterior or, optionally, also images of the vehicle interior. In one example, at least one camera is arranged at the vehicle to record the exterior of the vehicle to generate dynamic images which correspond to images usually shown by a rear mirror. However, the camera can be arranged such that it captures dynamic images which go beyond those which a rear mirror usually is able to capture; and the monitor portion 88 is capable of displaying such images with enhanced features, some of which are described below.
[0070] In one or more examples, the at least one camera can be arranged such that it detects dynamic images also in those areas which usually would lie in a blind spot area of a driver. Accordingly, the at least one camera can be used for blind spot detection and the monitor portion 88 can be controlled to display a warning feature when an approaching object is detected in the blind spot area. For example, when a vehicle is approaching from behind on a different lane, the at least one camera may detect the vehicle. If it is still far away, there may be no additional information provided by the monitor display 88. However, when the approaching vehicle comes within a few meters of the vehicle having the trim part, the monitor portion can display a warning feature in a dedicated area, such as a red light icon, red light stripe or flashing red light or the like. The monitor portion also could display a feature symbolizing the approaching vehicle, an arrow pointing in the direction where the vehicle is approaching from, or the like. As the vehicle continues to approach, the warning feature may move across the monitor portion 88 to illustrate the approaching vehicle. Further, the color of the warning feature may change.
[0071] The monitor portion 88 also can be controlled for image enhancement, such as providing augmented information. For example, in a no passing zone, the middle lane marking of a road may be overlaid by a red line in the rearview camera image. Additionally, as a further example, if a driver were to use the left turn signal in a no passing zone to start overtaking the vehicle, the red light stripe could start sending an additional warning by changing color or flashing. As another example, if the vehicle is in reverse gear, street lanes and the vehicle's projected path may be shown as overlays in a rearview camera image.
[0072] In one or more examples, it further is possible to control the monitor portion in such a way that it is in an idle mode or standby mode while not needed, in order to avoid distracting the driver by moving images. The detection device 44 may be used to detect a gesture of the driver, head movement of the driver or the driver looking at the monitor portion. Upon detection of a gesture, head or eye movement of the driver, the monitor portion 88 may wake up instantly to light up and bring into focus the rearview camera image displayed on the monitor portion 88. The monitor portion 88 may be controlled such that the image is displayed for a predetermined amount of time after a respective gesture, head movement or eye movement of the driver has been detected and/or as long as a respective gesture, movement or eye movement of the driver is detected plus a threshold time.
[0073] Alternatively or additionally, the monitor portion 88 may be activated by pressing a respective bottom (not shown) displayed on the monitor portion 88 or provided outside of the monitor portion for activating and/or setting the display of the camera image. Also the detection device 44 may be activated in this way. Additionally, the detection device 44 may be used for tracking the driver's eye movement and adjusting the camera and display of camera image on the monitor portion 88 accordingly.
