[0006] In this context, the object of the present invention is to appropriately present the logo of a vehicle.
[0007] The display system and method having the features of the independent claims achieve this object. Embodiments of the display system and method are given in the dependent patent claims and the description.
[0008] The display system according to the invention is designed for a vehicle, for example a motor vehicle. The display system has: a display area; an optical (e.g., optically variable adjustable) light-shielding member, which is usually digital, controllable, and / or switchable; and a control device, wherein the optical light-shielding member is arranged on, in front of, and / or above the display area and at least partially, possibly completely, and usually physically covers the display area. The display area is designed to present a display content, wherein the control device is designed to automatically drive the light-shielding member by a - usually digital - signal, such as a so-called light-shielding member signal and / or a design pattern signal, wherein the switchable optical light-shielding member is designed to selectively present a design pattern, such as at least one symbol and / or a template, in consideration of the signal provided by the control device for driving, that is, to present the design pattern or alternatively to prevent or avoid presenting the design pattern, wherein the purposefully presented design pattern at least partially. That is, only partially or completely. Usually optically covers and / or superimposes the display area, and usually also optically covers and / or superimposes the display content of the display area, regardless of whether the display area actively presents the display content. Here, the control device is connected to the light-shielding member and the display area by a line for signal transmission. In a feasible embodiment, the design pattern can be illuminated from behind or below by the display content of the display area arranged behind or below the display content.
[0009] An optically controllable and / or switchable light barrier or a corresponding light barrier plate, which can be controlled and / or switched by a light barrier signal - usually a digital light barrier signal - is designed, for example, as a switchable glass, as a thin-film transistor display (TFT) which is usually not illuminated (i.e., a thin-film transistor with liquid crystal, but without backlight or background illumination) and / or has electronic ink. Usually, a TFT array or a thin-film transistor region with a liquid crystal matrix (TFT + liquid crystal) can also be used as a light barrier or an optical light barrier plate. It is feasible here that the light barrier signal of the control device is an electrical signal and is provided by at least one electrical parameter. Here, at least one electrical parameter of the light barrier signal includes the voltage applied to the light barrier and / or the current conducted, wherein the design pattern is selectively generated based on at least one electrical parameter from the light barrier and / or related to the light barrier. Alternatively or additionally, the display area also has light-emitting elements (lighting elements), usually semiconductor-based light-emitting elements, which are designed as light-emitting diodes (LEDs), organic light-emitting diodes (OLEDs) or small light-emitting diodes, such as micro light-emitting diodes (μLEDs). Here, the display area is highly segmented and has a certain number of light-emitting elements. Here, the display area can have a small or large number of light-emitting elements, such as pixels. In one variant, it is also feasible that the display area is designed as a liquid crystal display, for example, a rear-illuminated LCD display or a liquid crystal display with backlight or background illumination, or the display area is designed as a simple, low-cost light source. Here, the display content provided by the display area designed as a light source is at least monochromatic. The light barrier is switched to be temporarily or permanently transparent and, with this design pattern, shows, for example, a logo. The light-emitting elements can be arranged in a chain or at least in a row. It is also feasible that the light-emitting elements are designed as light conductors. The display content can be static or animated. It is also feasible to use the display area to show, for example, a warning symbol or a company logo as the display content.
[0010] The light-shielding member is designed as a visible component in front of and / or above the display system, and the display area is designed as a visible component behind and / or below the display system. In an embodiment, it is feasible that the light-shielding member has at least one section or at least one area for display, namely the so-called design pattern area, such as a symbol area, and a design pattern is selectively shown by, from, and / or on this design pattern area. Among them, at least one area for the design pattern is selectively switched to be at least partially, possibly completely or wholly light-transmissive or transparent, such as colored, namely monochromatic or polychromatic, and can also be metallic, black or white for example. Correspondingly, the design pattern is shown at least partially, possibly completely, and light-impermeably. The color of the design pattern can be static or dynamically changing. Among them, the design pattern can also be shown in an animated manner, possibly completely. It is also feasible to set at least one area for the design pattern to be transparent and further set the color of the display content, which can be metallic for example. Accordingly, the colored, such as metallic, display content is visible through at least one area of the light-shielding member that is switched to be transparent, and correspondingly, the design pattern appears in color.
[0011] Furthermore, the light-shielding member can be divided into at least two different areas or sections. Among them, generally through the light-shielding member signal of the control device, at least one area is switched to be at least partially light-transmissive, namely only partially or completely light-transmissive, while at least another area is switched to be at least partially light-impermeable, namely only partially or completely light-impermeable. Each such area has a certain area. The light-shielding member can be dynamically and flexibly divided into a predetermined number of different areas, and these areas can be further deformed and changed according to the size of the area. Here, the design pattern is shown by or with the light-shielding member in at least one area that is generally centered and symmetrically arranged, namely the so-called design pattern area. This design pattern area is surrounded or encircled by at least one so-called background area that is another area of the light-shielding member. Here, the light-shielding member is divided into at least one design pattern area and at least one background area for the design pattern. Here, according to the shape of the design pattern, it is also possible that at least one design pattern area also surrounds or encircles at least another background area, where the outline of the design pattern is visually highlighted. Here, on the one hand, it is feasible that at least one design pattern area for the design pattern is switched to be light-transmissive, while at least one background area is switched to be light-impermeable. On the other hand or alternatively, at least one design pattern area for the design pattern is switched to be light-impermeable, while at least one background area is switched to be light-transmissive. Here, the display area and the display content shown thereon are visible through at least one light-transmissive area of the light-shielding member, and are invisible through at least one light-impermeable area because the display area and the display content are generally optically covered or will be optically covered by this light-impermeable area.
[0012] Here, on the one hand, it is feasible that the design pattern is shown in a positive manner on at least one design pattern area that is switched to opaque within at least one background area that is switched to transparent, and is optically highlighted by the display content of the display area shown behind the design pattern, and the display content of the display area is illuminated by at least one background area. On the other hand, it is also feasible that the design pattern is shown in a negative manner on at least one design pattern area that is switched to transparent within at least one background area that is switched to opaque, and is optically highlighted by the display content of the display area shown behind the design pattern, and the display content of the display area is illuminated by at least one design pattern area. The light-shielding member dynamically or statically divides and / or subdivides or switches to at least two areas, that is, at least divided into a design pattern area and a background area, or corresponding zoning.
[0013] The light-shielding member arranged on or in front of the display area can have an area smaller than the area of the display area, or an area equal to the area of the display area, and in the latter case, it completely coincides with the display area. The light-shielding member or its area is at most the same as or larger than the display area or its area, and it is feasible that the light-shielding member located on or in front of the display area is at least implemented in an optically visible manner on or in the display area. The light-shielding member is also mechanically connected directly or indirectly to the display area through a connecting element, usually directly or indirectly fixed on the display area. If the light-shielding member is larger than the display area, the light-shielding member will cover the display area located behind and / or below the light-shielding member, and the entire display system can be formed into a seamless structure.
[0014] Generally, the design pattern is shown by at least one design pattern area of the light-shielding member. Usually, the color display content of the display area is visible through at least one transparent area, that is, depending on the switching of the light-shielding member by the control device, either visible through at least one design pattern area of the light-shielding member or visible through at least one background area of the light-shielding member, and conversely, it is covered by at least one area switched to opaque (usually optically).
[0015] If the design pattern is shown in at least one design pattern area within at least one background area that is switched to opaque, and is typically shown in at least one color, for example a metallic color, at least one color of the design pattern can be static or can change dynamically. In this case, the design pattern can also be shown in animated form, if possible completely. Alternatively, the design pattern is shown in a light-transmissive manner within at least one design pattern area, where at least one background area of the light-shielding member is switched to opaque. Additionally, the entire light-shielding member can be switched to light-transmissive, where the area of at least one design pattern area is reduced to zero and the area of at least one light-transmissive background area expands to the entire light-shielding member, and the design pattern is selectively not shown. It is feasible here to set the design pattern area accordingly and define the shape of the design pattern. It is also conceivable that the light-shielding member has the shape of the design pattern, where the light-shielding member includes the entire design pattern area in the embodiment and is either set to be colored or light-transmissive.
[0016] It is feasible that the light-shielding member is designed to be static or unchanging and has a static or fixed design pattern, so that it always has the same, unchanging design pattern. In this case, the light-shielding member with the design pattern remains permanently partially transparent, where only the background area can be switched between transparent and opaque or non-light-transmissive. The logo of a motor vehicle manufacturer can be permanently shown, for example, through the static design pattern. The design pattern on the light-shielding member can also be switched between transparent and opaque or non-light-transmissive, where in this case the background area is always transparent. The manufacturer's logo can be presented as opaque, for example colored, such as white, or disappear in the activated state. When the display area is in the activated state, the design pattern can be illuminated and / or shown by the display content of the display area, where the entire area of the display area is used to show the display content.
[0017] It is also possible that the shade and the design to be displayed by the shade are designed to be dynamic and variable, wherein an active state and a passive state are set or can be set for the shade, wherein in the active state, the shade is electrically connected to the control device and supplied with current and / or voltage by the control device and is driven by the shade signal. In the passive state, on the other hand, the shade is usually electrically disconnected from the control device and is neither powered by the control device nor driven by the control device. Here, when the shade is in the active state, the shade is designed to set or possibly also change the design to be selectively displayed by the shade according to the signal of the control device, usually according to the shade signal, wherein the shape, color and / or size of the design can be changed. The design can have or display a single color or multiple colors by at least one design area switched to be opaque, wherein the colored design can also be metallic and therefore reflective or specular. If at least one design pattern area is switched to be light-transmissive and at least one background area is switched to be opaque, then the display content is visible through the at least one design pattern area and also appears metallic, which can also be metallic and therefore reflective or specular. It is also possible to alternately display different designs using a shading element.
[0018] The shading element is further designed to optically fix and / or hold, for example retain, a design pattern display state set by the control device and predetermined by the shading element signal. Even in the passive state, if the control device does not provide the shading element with a shading element signal, the shading element is designed to hold and / or retain the display state set for the design pattern without the need for a current and / or voltage supply from the control device.
[0019] The control device is also designed to control the display area or display screen independently of the shading member signal through an additional signal, such as a digital display signal, and to display the display content. Here, the control device can control or drive the shading member and the display area separately or individually, and can also dynamically set or change the display content, wherein the display content can also be displayed in an animated manner. Here, an active state and a passive state can also be set for the display area, wherein, in the active state, the display area is electrically connected or communicated with the control device or connected, and is driven by a display signal for displaying the content, and the display content is static or dynamically changing. On the contrary, in the passive state, the display area is closed and electrically disconnected from the control device. It is feasible that the display content set in the active state is also fixed (locked) and / or retained on the display area in the passive state. In these two states, the display content can be colorful, such as metallic, black or white.
[0020] Furthermore, when the display area is in the active state and is illuminated, lit by, or along with the displayed content, a warm color design pattern can be set, preset, and / or provided for the visible components of the display system, namely, the light-shielding member and the display area; alternatively, when the display area is in the passive state and not illuminated, a cool color design pattern can be set, preset, and / or provided. Generally, when and possibly only when the display area is in the active state, the light-shielding member is set to the active state, where once the design pattern, such as at least one symbol, is fixed, the light-shielding member can be set to the passive state. In the warm color design pattern, the display area is in the active state, while the light-shielding member is in the active state or the passive state. In the cool color design pattern, the display area is in the passive state, and the light-shielding member is generally in the passive state, where if necessary, the design pattern should be changed, and the light-shielding member in the cool color design pattern can also be opened and set to the active state.
[0021] In both the warm color design pattern and the cool color design pattern, the light-shielding member can also be switched to fully transparent or opaque in the active state and switched to fully transparent or opaque in the passive state. Here, when the light-shielding member is transparent or switched to transparent, the display area is fully visible and not optically covered. This is feasible if the visible components, namely, the light-shielding member and the display area, are located on the outer wall or the inner wall (depending on the implementation).
[0022] In particular, the display content of the display area arranged on the outer wall is designed to provide and / or present information to other road users in the vicinity of the vehicle, such as information about the future driving trajectory and / or functions that the vehicle has performed or will perform. The display area is arranged on and / or above the outer wall at the front or rear of the vehicle and can extend across the entire transverse axis of the vehicle, where the display content can be presented across the entire width of the vehicle. The display area can, for example, present animated light signals for the vehicle's external lighting as a possible display content. Here, these light signals can be used to present and display to other road users possible functions such as a change in the vehicle's driving direction (similar to an indicator light), braking (similar to a brake light), and / or reverse (similar to a reverse light). It is also feasible that the display content of the display area presents and / or simulates dipped headlights, high beams, tail lights, and / or fog lights as external lighting. The display content can be dynamically adapted and / or changed, where at least one external lighting and / or at least one function can be presented in combination with each other. It is also feasible to use the display area to provide optical and / or light-supported communication and / or interaction with other road users (C2X, vehicle-to-X), such as interaction with other vehicles, typically vehicle-to-vehicle communication (C2C, vehicle-to-vehicle), for example by presenting design patterns as the display content. Generally, the display content presenting information and / or warnings about other road users is presented using the display area, where a traffic safety function is provided. For example, this also includes presenting a proximity detection function to prevent rear-end collisions.
[0023] The display area and the light shield are arranged on and / or above the outer wall of the vehicle, typically on the vehicle body, or on and / or above the inner wall inside the vehicle. Alternatively or additionally, the light shield and the display area can also be arranged symmetrically with respect to the central longitudinal axis of the vehicle parallel to the driving direction, which serves as the axis of symmetry, where the display area can extend across the entire width of the vehicle, for example at the front or rear. With this centered positioning, only a single display area is required to display information in a communication (vehicle-to-X) manner because the axis of symmetry passes through the center of the display area or display screen and the center of the vehicle.
[0024] The method according to the invention is designed to generally display design patterns, such as at least one symbol and / or pattern, numerically and / or selectively on or in front of the display content by means of a display system for a vehicle, for example by means of an embodiment of the proposed display system. The display system has a display area, a controllable and / or switchable optical light shield, and a control device. The optical light shield is arranged on, in front of, and / or above the display area and can be switched completely digitally and changed if possible. Here, the display content is presented by the display area. The light shield is automatically controlled by a signal from the control device, which is usually a digital signal, such as a so-called light shield signal. Considering the signal provided for driving, the design pattern is selectively presented by the switchable optical light shield, and the display area and the display content usually presented by the display area are at least partially (i.e., partially or, if possible, completely) optically covered by the presented design pattern. However, it is also possible that the control device deletes and / or does not present the design pattern using the light shield signal, canceling the purposeful and controlled presentation of the design pattern.
[0025] In an embodiment, the design pattern and the display content behind the design pattern are presented synchronously in combination. Usually, the display content is adapted and changed by a display signal provided by the control device, which is usually digital, automatic, and / or dynamic. In contrast, in the activated state, the design pattern is set at least once, usually only once, by a light shield signal or a design pattern signal provided by the control device, and then further statically fixed or held, for example retained. It is possible that after setting and usually fixing the design pattern, the light shield is electrically disconnected from the control device and set to a passive state. Usually, the static design pattern is also further presented on and / or in front of the display area in the passive state and thus on and / or in front of the display content. It is possible that at least one color selected or set for the design pattern, or already set, is also fixed and held in the passive state. If at least one area for the design pattern on the light shield is transparent in the passive state of the light shield, the display area can also be set to or can be in a passive state, and the color of the display content (such as metallic, black, or white) is fixed and visible through at least one transparent area.
[0026] For example, a numerically set design pattern or a digital design pattern can also be designed or referred to as a logo, such as a brand logo, thus indicating a symbol of the vehicle manufacturer. However, it is conceivable that the design pattern or its appearance can be selected and / or modeled by the user of the vehicle. The user presets their predetermined design pattern, for example, individually, via an input device and then provides the control device with predetermined parameters for the light shield signal. The design pattern can include at least one symbol and / or at least one character, such as text, i.e., at least one letter and / or one number.
[0027] In the activated state during normal vehicle operation and in the passive state when the vehicle is parked, the design pattern, such as a digital brand logo, presented by the light-shielding member can be seen because, in the passive state, the design pattern was previously fixed in the activated state of the light-shielding member and continues to be retained and displayed or presented without being affected by the control device. The method and the display system are also provided for vehicles that can travel at least temporarily, autonomously, or automatically and / or under machine control. A vehicle equipped with the display system can communicate with other road users (such as pedestrians or cyclists) using the design pattern and the display content through the display system. Feasible use cases include early communication, where, for example, specific dangerous situations or the like are indicated. Here, if there is no direct eye contact between the vehicle driver and other road users, the function can also be assumed and information can be provided, such as resolving a stalemate or a dead-end situation, etc. This is also feasible when the vehicle is semi-automatically driving, allowing the driver to take their eyes off the road surface.
[0028] If another road user, i.e., another vehicle, such as a so-called environmental vehicle / external vehicle, has sensors, such as cameras, for optically recognizing the display content of the display system of a vehicle equipped with the display system, such as a so-called autonomous vehicle, the autonomous vehicle can also communicate and / or interact with this other road user through the displayed, for example, animated, display content. In addition, the autonomous vehicle can also have sensors, such as cameras, for optically recognizing the display content presented in the display area of the environmental vehicle, where the display area can likewise be designed as a component of an embodiment of the proposed display system. The sensors of the autonomous vehicle can exchange information with the control device of the display system and are optionally also designed as components of the display system. Two vehicles, namely the autonomous vehicle and the environmental vehicle, can generally automatically communicate and / or interact with each other through mutual sensor recognition of the optical display content, and thus can also warn each other of possible dangerous traffic situations, where vehicle-to-vehicle optical communication is feasible, in which data and / or information can be optically transmitted between the vehicles. Generally, the autonomous vehicle can also communicate optically with people, namely pedestrians and the occupants of the environmental vehicle, and provide them with information.
[0029] For two visible components of a display system, at least three different operating modes can be set. In the first and second operating modes, a design pattern, such as a logo, is presented through a light-shielding member in an active state and a passive state. In the first operating mode, the display area is in an active state, where the design pattern is illuminated by the display content presented behind or below the design pattern in the display area. In the second operating mode, the display area is in a passive state, where the design pattern is not illuminated by the display content presented behind or below the design pattern in the display area, that is, the design pattern remains unilluminated but is still visible. In the third operating mode, the light-shielding member is and / or is switched to be completely light-transmissive or transparent in the active state and the passive state, so that the display content of the display area is completely visible through the light-shielding member, because the design pattern is invisible, and the display area can be completely or fully used to display the display content. Through the combination of the light-shielding member and the display area, the operating mode and / or function can be depicted or presented, and among them, a design pattern, such as a manufacturer's logo, can be produced with high quality in a cold color state.
[0030] The display area in an active state can display different functions, such as functions and / or safety functions, through the display content, and / or set a personalized design pattern, such as a lighting pattern, for the user. It is also feasible that the user can personalize the design pattern, such as a symbol. The preset parameters for the specific operating mode and / or design pattern can be input by the user into the input device and / or loaded from the database. The display system can also be used to set the color of a vehicle, and the color can be switched between different colors.
[0031] It can be understood that the functions mentioned above and the features to be explained below can not only be used respectively in the given combinations, but also in other combinations or alone without exceeding the scope of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
[0032] The present invention is schematically illustrated in the drawings by means of embodiments and described schematically and in detail with reference to the drawings.
[0033] Figure 1a 、 Figure 1b 、 Figure 1c The figure shows a schematic diagram of an embodiment of a display system according to the present invention when implementing an embodiment of the method according to the present invention.
[0034] Describe the drawings coherently and comprehensively. The same components are given the same reference numerals. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0035] Figures 1a to 1cEmbodiments of a display system for a vehicle (here a motor vehicle) according to the invention are shown respectively in different operating modes. The display system has a light-shielding member 2 and a display area 4 as visible components, wherein the light-shielding member 2 is arranged on or in front of the display area 4 and is directly or indirectly connected to the display area 4, for example, directly or indirectly fixed to the display area 4. In Figure 1a , Figure 1b , Figure 1c , each shows the light-shielding member 2 and the display area 4 from the main viewing angle, wherein Figures 1a to 1c , each also shows details of the light-shielding member 2 and the display area 4 in a cross-sectional view. As a further component of the display system, the control device 20 is at least temporarily electrically connected and drives or alternatively electrically disconnects and / or does not drive at least one of the two visible components, wherein, if the light-shielding member and the display area are electrically connected to the control device 20 and are driven, the light-shielding member 2 or the display area 4 is set to an active state; wherein, if the light-shielding member and / or the display area are electrically disconnected from and / or not driven by the control device 20, the light-shielding member 2 or the display area 4 is set to a passive state.
[0036] In an embodiment of the method according to the invention, if an optically switchable and / or adjustable light-shielding member and / or display area is electrically connected to the control device 20 to exchange signals, the light-shielding member 2 and the display area 4 or the display screen are controlled by the signals of the control device 20, that is, controlled by a light-shielding signal for the light-shielding member 2 and a display signal for the display area 4, for example, driven, and thus also switched.
[0037] Here, the light-shielding member 2 for displaying a design pattern driven by a light-shielding member signal is divided or segmented into a design pattern area 6 for the design pattern and a plurality of background areas 8 as the background for the design pattern. Here, the switchable light-shielding member 2 is designed as, for example, switchable glass, a thin-film transistor display screen or has electronic ink. The display area 4 for displaying display content has light-emitting elements, such as light-emitting diodes (LEDs) in the form of organic light-emitting diodes (OLEDs), or is designed as a thin-film transistor LC display screen (LCD-TFT or liquid crystal thin-film transistor display screen) that is usually backlit. Here, these two visible components are arranged on the wall of the vehicle, that is, on the outer wall or the inner wall in the interior space of the vehicle occupant. The control device 20 can also control other functions of more systems of the vehicle, regardless of the proposed method.
[0038] The design pattern shown here includes four adjacent and connected rings, for example, representing Audi (TM)The company logo of a joint-stock company, where every two directly adjacent rings intersect and are connected to each other. Here, the rings or their contours are shown by a design pattern area 6 located inside an outer background area 8 surrounding the design pattern area 6, where the design pattern area 6 surrounds or encloses another background area 8 defined by the contours of the rings.
[0039] In an embodiment of the method proposed herein, the light-shielding member 2 and the display area 4 are first each driven to an active state by signals from the control device 20, where the design pattern area 6 is switched or set to be light-transmissive or transparent. Additionally, in the active state, at least one color, i.e., only one color or multiple colors, is shown as the display content of the display area 4. Even in the passive or inactive state of the display area, at least one color of the display area is visible or remains visible. If the display area includes an organic light-emitting diode (OLED), it is feasible for the display content to present a metallic color, such as silver or chrome, where the color can be predetermined in terms of hardware by the organic light-emitting diode.
[0040] Here is formed Figure 1a The first operating mode shown, in which a warm-tone design pattern can be achieved if or as long as at least one of two visible components (here at least the display area 4, and possibly also the light-shielding member 2) is in the active state. If the light-shielding member 2 is in the active state, it is feasible to fixedly divide the light-shielding member 2 into a design pattern area 6 and a background area 8 and keep the light-shielding member in the passive state after electrical disconnection from the control device 20. If the display area 4 is in the active state, it is also feasible to fix the display content of the display area 4, here the set metallic color, and keep this display content after electrical disconnection from the control device 20. Alternatively, the color of the display content can be predetermined in terms of hardware in both the active and passive states. After the light-shielding member 2 and the display area 4 are electrically disconnected from the control device 20, a cold-tone design pattern is produced in the passive state of the light-shielding member 2 and the display area 4 as a second operating mode, which also remains when the vehicle is parked and turned off. In both of these operating modes, for example, silver rings are shown in front of a black background and present a traditional logo designed as a badge on the vehicle body.
[0041] Another feasible third operating mode is shown schematically by Figure 1b Here, what is retained is in Figure 1aIn the working mode, the light-shielding member 2 is divided into a design pattern area 6 and a background area, which is feasible whether the light-shielding member 2 is in an active state or a passive state. In addition, the display content of the display area 4 is changed. Here, the color of the display area is changed from a metallic color to a luminescent color in the color spectrum, such as red. As long as the display area 4 is in an active state, the light-transmitting design pattern area 6 of the light-shielding member 2 is illuminated and / or penetrated by the display content with the luminescent color, and a warm-tone design pattern is achieved.
[0042] In the fourth working mode ( Figure 1c ), the entire light-shielding member 2 is switched to be light-transmitting, which means that the area of the design pattern area 6 is reduced to zero in the active state and the design pattern area 6 is removed; correspondingly, at this time, only the background area 8 that is switched to be light-transmitting or its area expands to the entire light-shielding member 2, and this remains unchanged when the light-shielding member 2 is placed in the passive state. In addition, as long as the display area is in an active state, the display area 4 will continue to display the luminescent color in the optical color spectrum as the display content, and a warm-tone design pattern is also achieved. However, it is also feasible for the display area 4 to display multicolor dynamic display content instead of static monochromatic display content, and these multicolor dynamic display content are completely visible through the completely light-transmitting switched light-shielding member 2 because the multicolor dynamic display content is not covered by the design pattern.
[0043] Generally, it is feasible that the light-shielding member 2 in the active state and / or the passive state is switched to be light-transmitting in at least one first area and light-impermeable in at least one second area due to being divided into at least two areas, namely at least one design pattern area 6 and at least one background area 8 ( Figure 1a and Figure 1b ), or is switched to be light-transmitting in all areas ( Figure 1c ), or is switched to be light-impermeable in all areas and in this case covers the display content. Therefore, each area can be optionally switched and / or set to be light-transmitting or light-impermeable. It should be noted here that in terms of hardware, the light transmittance of each area usually cannot be set to 100% light-transmitting or transparent or 0% light-impermeable because each area can only be set to be completely light-transmitting or light-impermeable in an idealized way.
