Description

Technical Field

[0001] The present invention relates to a smart glass device and a system comprising at least one smart glass device. Background Technology

[0002] Devices for displaying information to vehicle users, particularly drivers, are known. For example, technical information can be provided to the driver on a display screen behind the steering wheel. Some vehicles also display information to the outside of the vehicle, such as buses.

[0003] However, known systems may have drawbacks. For example, they may not provide sufficient contrast, especially during the day. Furthermore, they cannot provide a three-dimensional (image) effect for the user and / or driver, particularly for individual and / or isolated portions and / or pixels of the image. Some known devices may be costly to manufacture and / or maintain. Their complexity may be unsatisfactorily high. Summary of the Invention

[0004] Therefore, one objective of the present invention may be to overcome (at least in part) at least one of the aforementioned disadvantages. Alternatively, an objective may be to provide an apparatus (and system) optimized in terms of cost, contrast, durability, viewing effect, and / or ease of use.

[0005] According to a first aspect of the invention, the aforementioned objective problem is solved by a smart glass device for a vehicle, optionally, the smart glass device for and / or attached to the exterior of a vehicle preferably such that the information displayed by the device can be seen from outside the vehicle (by a user and / or other persons), the device comprising:

[0006] - A backlight layer extending along a first direction and a second direction, optionally perpendicular to a third direction, wherein the backlight layer is configured to provide background illumination, optionally providing background illumination along a third direction and / or toward a first, second and / or at least one third glass layer;

[0007] - A first glass layer, which is separated from the backlight layer by a first distance (e.g., 1 mm) along a third direction, wherein the first glass layer includes a first liquid crystal display, the first liquid crystal display comprising a first group of multiple (3D) segments, wherein the first group of multiple segments can be individually controlled, optionally (switchable; "on" and "off") by an electronic control unit;

[0008] - A second glass layer, which is a second distance (e.g., 1 mm) from the first glass layer along a third direction, wherein the first glass layer is located between the backlight layer and the second glass layer, wherein the second glass layer includes a second liquid crystal display, the second liquid crystal display comprising a second group of multiple (3D) segments, wherein the second group of multiple segments can be individually controlled, optionally, (switchably) controlled by an electronic control unit.

[0009] The first, second, and / or third coordinates can be perpendicular to each other and / or can form a right-handed coordinate system. Preferably, the smart glass device and / or system is configured for vehicle exterior trim.

[0010] The backlight layer, the first glass layer, the first liquid crystal display, the second glass layer, the second liquid crystal display, and at least one third glass layer and / or the third liquid crystal display may include:

[0011] - The (same) extension along the first direction (e.g., 30 cm) and / or the second direction (e.g., 10 cm); and / or

[0012] - (at least partially) an orientation perpendicular to a third direction; and / or

[0013] - Plate-like and / or three-dimensional (geometric) shape; and / or - thickness between 0.1 mm and 5 mm.

[0014] The backlight layer, the first glass layer, the first liquid crystal display, the second glass layer, the second liquid crystal display, and at least one third glass layer and / or the third liquid crystal display can be:

[0015] - (roughly and / or at least partially) parallel to each other; and / or

[0016] - Symmetrical with respect to a plane perpendicular to the first, second, and / or third directions; and / or

[0017] - Aligned and / or arranged relative to a third party; and / or

[0018] - In the shape of a cube; and / or

[0019] - Directly adjacent to each other, preferably along a third direction, specifically such that the following sequence is achieved: backlight layer, first glass layer, second glass layer, at least one third glass layer (and possibly more third glass layers subsequently); and / or

[0020] - Controlled by an electronic control unit, such as the vehicle's electronic control unit, optionally, via individual control signals, for example, for each (individual) segment; and / or

[0021] - Configured to jointly provide a combined image to the user (viewing in the opposite direction to a third party), optionally, providing background lighting through a backlight layer, providing a first image through a first glass layer, providing a second image through a second glass layer, and / or providing a third image through at least one third glass layer.

[0022] Preferably, each segment of the first group, the second group, and / or (at least one) third group of multiple segments (and / or glass layers) may include:

[0023] - Same shape; and / or

[0024] - Same size; and / or

[0025] -Identical first, second and / or third surfaces; and / or

[0026] - The same orientation, optionally, relative to the first, second and / or third orientation.

[0027] The first, second, and / or at least one third glass layer and / or the portion of the liquid crystal display not covered by segmentation may include (common) transparent materials, such as glass and / or plastics (e.g., polycarbonate).

[0028] The backlight layer is configured to provide background illumination (e.g., when controlled by an electronic control unit), optionally providing background illumination along a third direction and / or toward the first, second, and / or at least one third glass layer. The backlight layer may include at least one or more light sources, such as LEDs. Preferably, the backlight layer can provide (uniformly, optionally, relative to the extent of the backlight layer's extension along the first and / or second directions) illumination (along a third direction). For example, a light source may be provided for each of a plurality of segments (a first group and / or a second group of multiple segments) (and this light source is aligned with the segment along a third direction).

[0029] The first glass layer may be adjacent to and / or attached to the backlight layer; for example, the first distance may be zero. The second glass layer may be adjacent to and / or attached to the first glass layer; for example, the second distance may be zero. At least one third glass layer may be adjacent to and / or attached to the second glass layer; for example, the second distance may be zero.

[0030] A first glass layer is positioned at a first distance (e.g., 1 mm) from the backlight layer along a third direction. The first glass layer includes a first liquid crystal display (LCD) comprising a first group of multiple (3D) segments, wherein each segment is individually controllable, optionally (switchable; “on” and “off”) via an electronic control unit. Thus, the electronic control unit can control each individual segment in the first group of multiple segments, for example, by sending control signals via a data communication line, preferably switching it between a first state and a second state. In the first state, the segment can be (at least partially) transparent; for example, 1% to 99% (preferably 12% to 50%) of the light (from the backlight layer) can pass through along (and / or opposite) a third direction (e.g., partial light blocking). In the second state, the segment can be (substantially) opaque; for example, only 0% to 1% of the light can pass through along (and / or opposite) a third direction (e.g., complete light blocking). By individually and / or separately controlling / switching the first group of multiple segments, a first image can be provided to the user (when viewed along [or opposite] a third direction) (similar to shading certain pixels of a computer monitor uniformly illuminated / white light). Each segment in the first group of multiple segments may include a first surface (oriented along a third direction). Each segment in the first group of multiple segments may include a complementary first surface (oriented opposite to the third direction), the shape of which may be the same as and / or aligned with the first surface along the third direction. For example, light emitted along the third direction due to the emission of the backlight layer may enter one / each of the first group of multiple segments (through the complementary first surface) and / or exit one / each of the first group of multiple segments (through the first surface). A (polarizable) medium may be placed between the first surface and the first complementary surface, which is preferably configured to be aligned (itself) along the third direction (and / or along the electric field). Optionally, when a voltage and / or current is applied to the first surface and / or the complementary first surface, the first surface and / or the complementary first surface may (each) include electrodes (e.g., in the shape of capacitor plates). In the first state, the segments (optionally, the medium) can be transparent (see above). In the second state, the segments (optionally, the medium) can be opaque and / or light-blocking (see above). Each segment and / or the first group of multiple segments can be symmetrical with respect to a plane perpendicular to the first direction, the second direction, and / or the third direction. The first group of multiple segments can be arranged in a (symmetrical) pattern, such as n x n, where n is a positive integer n = {1, 2, 3, 4, 5, 6, 7, 8, 9…}.

[0031] The second glass layer is positioned a second distance (e.g., 1 mm) from the first glass layer along a third direction. The second glass layer includes a second liquid crystal display comprising a second group of multiple (3D) segments, wherein the second group of multiple segments is individually controllable, optionally (switchable; “on” and “off”) via an electronic control unit. Thus, the electronic control unit can control each individual segment in the second group of multiple segments, for example, by sending control signals via a data communication line, preferably switching it between a first state and a second state. In the first state, the segment can be (at least partially) transparent; for example, 1% to 99% (preferably 12% to 50%) of light can pass through along (and / or opposite) a third direction (e.g., partial light blocking). In the second state, the segment can be (substantially) opaque; for example, only 0% to 1% of light can pass through along (and / or opposite) a third direction (e.g., complete light blocking). By individually and / or separately controlling / switching the second group of multiple segments, a second image can be provided to the user (when viewed along [or opposite] a third direction) (similar to shading certain pixels of a computer monitor uniformly illuminated / white light). Each segment in the second group of multiple segments may include a second surface (oriented along a third direction). Each segment in the second group of multiple segments may include a complementary second surface (oriented opposite to the third direction), the shape of which may be the same as and / or aligned with the second surface along the third direction. For example, light emitted along the third direction due to emission from the backlight layer and / or through the first glass layer may enter one / each of the second group of multiple segments (through the complementary second surface) and / or exit one / each of the second group of multiple segments (through the second surface). A (polarizable) dielectric can be placed between the second surface and the second complementary surface. This dielectric is preferably configured to align itself along a third direction (and / or along an electric field). Optionally, when a voltage and / or current is applied to the second surface and / or the complementary second surface, each may include electrodes (e.g., in the shape of capacitor plates). In a first state, the segments (optionally, the dielectric) can be transparent (see above). In a second state, the segments (optionally, the dielectric) can be opaque and / or light-blocking (see above). Each segment and / or the second group of multiple segments can be symmetrical with respect to a plane perpendicular to the first, second, and / or third direction. The second group of multiple segments can be arranged in a (symmetrical) pattern, e.g., n x n, where n is a positive integer n = {1, 2, 3, 4, 5, 6, 7, 8, 9…}.

[0032] Within the scope of this invention, an apparatus may be provided, comprising:

[0033] At least one third glass layer is located at a third distance from the second glass layer along a third direction, wherein the second glass layer is located between the first glass layer and at least one third glass layer, wherein the at least one third glass layer includes a third liquid crystal display, the third liquid crystal display comprising a third group of multiple segments, wherein the third group of multiple segments can be controlled individually, and optionally, (switchably) controlled by an electronic control unit.

[0034] At least one third glass layer is positioned along a third direction at a third distance (e.g., 1 mm) from the second glass layer and / or any preceding (third) glass layer, wherein each of the at least one third glass layer comprises a third liquid crystal display containing a third group of multiple (3D) segments, wherein the third group of multiple segments is individually controllable, optionally (switchable; “on” and “off”) by an electronic control unit. Thus, the electronic control unit can control each individual segment of the third group of multiple segments, for example by sending control signals via a data communication line, preferably switching it between a first state and a second state. In the first state, the segment can be (at least partially) transparent; for example, 1% to 99% (preferably 12% to 50%) of the light (that has already passed through the preceding layers) can pass through along (and / or opposite) a third direction (e.g., partial light blocking). In the second state, the segment can be (substantially) opaque; for example, only 0% to 1% of the light (that has already passed through the preceding layers) can pass through along (and / or opposite) a third direction (e.g., complete light blocking). By individually and / or separately controlling / switching the third group of multiple segments, a third image can be provided to the user (when viewing along [or opposite] a third direction) (similar to shading certain pixels of a computer monitor uniformly illuminated / white light). Each segment in the third group of multiple segments may include a third surface (oriented along the third direction). Each segment in the third group of multiple segments may include a complementary third surface (oriented opposite to the third direction), the shape of which may be the same as and / or aligned with the third surface along the third direction. For example, light emitted along the third direction due to emission from the backlight layer and / or through the first glass layer and / or the second glass layer and / or any other front layers may enter one / each of the third group of multiple segments (through the complementary third surface) and / or exit one / each of the third group of multiple segments (through the third surface). A (polarizable) dielectric may be placed between the third surface and the third complementary surface, preferably configured to align itself along a third direction (and / or along an electric field). Optionally, when a voltage and / or current is applied to the third surface and / or the complementary third surface, the third surface and / or the complementary third surface may each include electrodes (e.g., in the form of capacitor plates). In a first state, the segments (optionally, the dielectric) may be transparent (see above). In a second state, the segments (optionally, the dielectric) may be opaque and / or light-blocking (see above). Each segment and / or the third group of multiple segments may be symmetrical with respect to a plane perpendicular to the first, second, and / or third directions. The third group of multiple segments may be arranged in a (symmetrical) pattern, for example, n x n, where n is a positive integer n = {1, 2, 3, 4, 5, 6, 7, 8, 9…}.

[0035] Preferably, the first image, the second image, and / or the third image and / or potential other images in subsequent (following) layers can be aligned and / or correspond to each other. Preferably, segments aligned and / or adjacent to each other along a third direction in the first, second, third, and / or other groups of segments can be individually controlled and / or controlled to switch to the same (first or second) state. For example, a single segment (e.g., the center segment of a 9x9 pattern of the first, second, third, and / or any other group of segments) can be switched to the first (or second) state simultaneously in the first, second, third, and / or any other glass layer to provide (at least partially) transparency (or opacity).

[0036] In the present invention, an apparatus may be provided in which a first glass layer and a second glass layer, optionally, at least a third glass layer, are identical in design, preferably identical in geometry, form and / or electrical layout.

[0037] This allows for low-cost production, ease of operation, ease of control, and / or ease of maintenance. Preferably, the size and / or area of ​​the segments (the only difference) between multiple segments can increase (or decrease) along or opposite to the third direction. In other words, the segments of the first glass layer can be larger than the segments of the second glass layer.

[0038] Within the scope of this invention, an apparatus may be provided in which a backlight layer, a first glass layer and / or a second glass layer, optionally, at least one third glass layer, are arranged (at least partially, substantially and / or completely) parallel and / or perpendicular to a third direction.

[0039] This facilitates production, assembly, and / or maintenance. Smart glass devices can include a sandwich-like structure. This can also improve durability and / or minimize overall size.

[0040] In the present invention, an apparatus may be provided in which a first liquid crystal display, a second liquid crystal display, and optionally a third liquid crystal display are configured to provide a three-dimensional image effect from at least an external viewing angle having a distance from the second liquid crystal display and / or from a third party to the third liquid crystal display. Optionally, when:

[0041] The first liquid crystal display is controlled to display the first image (or the negative display of the first image);

[0042] The second liquid crystal display is controlled to display the second image (or the negative of the second image); and / or

[0043] The third LCD display is controlled to display the third image (or the negative of the third image).

[0044] Each segment of the first group of multiple segments can be controlled by an electronic control unit to provide and / or display a first image (or its corresponding negative display), optionally by switching to a first and / or second state according to a first pattern (which is specific to the first image). For example, the segments of a 9x9 pattern can be controlled to block light from a portion of the segment, thereby displaying a number (e.g., the number "2").

[0045] The individual segments of the second group of multiple segments can be controlled by an electronic control unit to provide and / or display a second image (or its corresponding negative display), optionally by switching between a first and / or second state according to a second pattern (which is specific to the second image). For example, the segments of a 9x9 pattern can be controlled to block light from a portion of the segment, thereby displaying a number (e.g., the number "2").

[0046] Each segment of a third group of multiple segments (or any other group of multiple segments in any subsequent layer) can be controlled by an electronic control unit to provide and / or display a third image (or its corresponding negative display), optionally by switching to a first and / or second state according to a third pattern (which is specific to the third image). For example, a 9x9 pattern segment can be controlled to block out portions of the segment, thereby displaying a number (e.g., the number "2").

[0047] Preferably, the corresponding and / or aligned segments (all) of subsequent, adjacent and / or all layers provide and / or display the same pattern and / or image.

[0048] Within the scope of this invention, an apparatus may be provided, wherein:

[0049] For the first group of multiple segments, each (segment) includes and / or covers the first surface; and / or

[0050] For the second group of multiple segments, each (segment) includes and / or covers the second surface; and / or

[0051] Optionally, for the third group of multiple segments, each (segment) includes and / or covers the third surface.

[0052] The first, second, and / or third surfaces may include rectangular, optionally square, shapes, optionally perpendicular to the third direction, wherein preferably, the edges are aligned along the first and / or second directions. This can provide a viewing experience similar to that of a computer screen.

[0053] The first, second, and / or third surfaces may include non-rectangular, optionally circular, and / or annular shapes, optionally perpendicular to the third direction. Their dimensions decrease (or increase) along the third direction (for different layers). This can provide a 3D viewing effect from more viewing angles that are not (exactly) along the third direction or in the opposite direction.

[0054] The first surface, the second surface, and / or the third surface can be considered as areas and / or ranges oriented and / or aligned along the first and / or second directions. In other words, they can be considered as areas and / or ranges visible (or [more precisely] shaded) when viewed along (or opposite) a third direction. The first liquid crystal display, the second liquid crystal display, and / or at least one third liquid crystal display and / or the glass layer can (at least partially and / or controllably) be transparent along the third direction and / or opposite to the third direction.

[0055] Preferably, adjacent first, second, and / or third surfaces of the first, second, and / or third groups of surfaces can be arranged on a regular (square) grid, optionally perpendicular to a third direction.

[0059] The area and / or size of the first surface can be larger than (or smaller than) the second and / or third surfaces. The area and / or size of the second surface can be larger than (or smaller than) the third surface and / or the surface of any segment of the front layer along a third direction. The area and / or size of the third surface can be larger than (or smaller than) the surface of any segment of the front layer along a third direction. In this way, a 3D viewing effect can be defined and / or provided.

[0068] Alternatively, they may include:

[0069] They have different lengths along the first direction; or

[0070] It has different lengths along the second direction.

[0071] Therefore, different image effects can be achieved, for example, if the user is expected to have a specific viewing angle relative to a third party (e.g., when the device is installed above the average height of a person).

[0072] Within the scope of this invention, an apparatus may be provided, wherein a first geometric shape and a second geometric shape, optionally a third geometric shape, comprise:

[0073] Different (two-dimensional) areas, optionally, relative to a first direction and a second direction; wherein they preferably include:

[0095] Multiple segments in the first, second, and / or third groups can be (designed) to form offset and / or staggered meshes, optionally, relative to the first, second, and / or third directions. This allows for (pre-)definition of angles that can provide a specific 3D viewing effect. For example, this can be simulated using simulation software during production and / or assembly.

[0096] Preferably, the offset between the multiple segments of the first, second, and / or third groups can be adjusted, for example, by screws located at the edges of the first, second, and / or at least third glass layers, optionally relative to the housing.
