Compared with using other locations in the car for display (such as displays on the back of the vehicle seats), car window glass is more convenient, has a larger available area, is more durable and provides a better user experience. For example, projection film can be applied to the rear windshield of a taxi to display advertising content such as pictures or videos to the outside of the vehicle.

[0003] Although projecting images to the outside of the vehicle through the window glass can meet the needs of some consumers, vehicle manufacturers and consumers expect that the projection display function on the window glass can provide a more diversified experience, and hope to adjust or improve the occasions and image quality of the projected images according to different needs.

[0046] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely exemplary of specific ways to implement and use the present disclosure, and are not intended to limit the scope of the present disclosure. When describing the structural positions of the various components, such as up, down, top, bottom, etc., the expressions of directions are not absolute, but relative. When the various components are arranged as shown in the figure, these directional expressions are appropriate, but when the positions of the various components in the figure change, these directional expressions also change accordingly.

[0047] Herein, the expression "includes" or similar expressions "having" and the like are open-ended and do not exclude additional unrecited elements, steps or components.

[0048] Herein, the terms "first", "second", etc. are not used to limit the order of precedence and the number of components, unless otherwise specified.

[0049] In this document, unless otherwise specifically defined, the terms "attachment" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in this document can be understood according to the specific circumstances.

[0050] As used herein, “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0051] Herein, the "surface" of a glass body or a laminated structure is defined by the plane where the length and width of the glass body or the laminated structure are located, and the "edge" is defined by the plane where the length or width and thickness of the glass body or the laminated structure are located. A "cross section" of a glass component is taken along the thickness direction of the glass component.

[0052] Herein, the glass assembly is described as being applied to vehicle window glass, but it does not exclude that the glass assembly may be applied to environments such as doors, windows, curtain walls, aircraft glass or ship glass. When the glass assembly is described as a vehicle window glass for a vehicle, "outside" and "inside" are directions relative to the vehicle body, "outside" refers to the direction away from the vehicle body, "inside" refers to the direction facing the vehicle body, and "vertical direction" refers to the direction roughly perpendicular to the ground. It should be understood that the vehicle window glass according to the embodiments of the present disclosure includes but is not limited to the front windshield, the rear windshield, the door glass (including the front door glass and the rear door glass) or the corner window glass, and different image display effects can be provided based on different needs.

[0053] In the various embodiments described, unless otherwise specified, the thickness of the glass is the thickness commonly used in the art, and the thickness of each laminated structure on the glass is applicable to the conventional range and is not limited to that shown in the figure. In addition, although the figure shows flat glass, the glass assembly of the present disclosure may also be curved glass. In various embodiments, it is described as an independent glass body, but in some cases not described, the surface of the glass body may also use a special coating to improve other properties such as heat insulation and / or comfort.

[0054] For manufacturers and most vehicle users, they hope to use car window glass to achieve image display effects, while providing privacy effects on image content and reducing the impact on people outside the vehicle. In this article, when images are displayed inside the vehicle, "privacy" refers to people inside the vehicle, that is, the car window glass can prevent people outside the vehicle from seeing the displayed image content, thereby achieving a privacy protection function. In this article, the displayed image is not limited, for example, it can be static text, numbers, symbols or pictures, or dynamic videos.

[0055] It is recognized that in the case of projecting into or out of a vehicle through window glass, the driver and passengers tend to be interested in images displayed in certain areas. For example, the driver and passengers prefer display areas with smaller head rotation angles, that is, areas on the door glass that are relatively closer to the front of the vehicle. This puts forward more diversified design requirements for the window glass.

[0056] According to the concept of the present disclosure, a glass component is provided, the glass component comprising: a glass body; a forward projection display layer, the forward projection display layer is arranged on the surface of the glass body, and is used to display an image to one side of the glass component; and a light-cutting layer, the light-cutting layer comprises a plurality of light-cutting regions, each of the light-cutting regions is configured to be switchable between a non-dark state and a dark state, wherein the light-cutting layer is arranged on the opposite side of the forward projection display layer from the displayed image.

[0057] Depending on different needs, the image display function provided by the forward projection display layer in the glass component of the present invention covers projection to the outside of the vehicle and to the inside of the vehicle, wherein "forward projection" refers to the light emitted by the projection device being projected onto the glass component to form an image, and then the light is reflected to the eyes of the observer, which is also called reflective projection. In comparison, "rear projection" refers to the light emitted by the projection device being projected from one side of the glass component, and the light passes through the glass component into the eyes of the observer on the other side, which is also called transmissive projection. Further, the glass component of the present invention provides a light-cutting layer including a plurality of light-cutting areas, and the light-cutting layer is arranged on the opposite side of the display image of the forward projection display layer, wherein "light-cutting" refers to the ability of the light-cutting layer to cut off light when it is in a dark state to prevent the light from being transmitted through the light-cutting layer, and the light-cutting layer can also be called a light valve. Here, "dark state" means that when the light-cutting layer is switched to this state, the visible light transmittance of the light-cutting layer is less than or equal to 10%, preferably less than or equal to 5%, for example, less than or equal to 4%, less than or equal to 3%, less than or equal to 2%, less than or equal to 1%, etc., or it is the minimum transmittance of the light-cutting layer (for example, 0.5%). "Non-dark state" means that when the light-cutting layer is switched to this state, the visible light transmittance is greater than the visible light transmittance in the dark state. For example, when the light-cutting layer is in the non-dark state, the visible light transmittance of the light-cutting layer may be greater than or equal to 20%, greater than or equal to 30%, greater than or equal to 40%, greater than or equal to 50%, greater than or equal to 60%, greater than or equal to 70%, greater than or equal to 80%, or it is the highest transmittance of the light-cutting layer. According to the present disclosure, the non-dark state of the light-truncation layer can include one or more stable states corresponding to different visible light transmittances, such as two, three, four, five or more, so that depending on different needs, different transmittances can be freely and infinitely adjusted without being limited to the highest transmittance of the selected light-truncation layer in different forms. In this way, the light-truncation layer in the dark state can intercept the light from the opposite side of the displayed image of the positive projection display layer, thereby improving the contrast of the image and enhancing the clarity of the image displayed on the positive projection display layer. When applied to, for example, door glass and displaying images to the interior of the vehicle, the glass assembly of the present disclosure not only allows people inside the vehicle to observe the enhanced projection image, but also can realize the function of protecting the privacy of the displayed image content and reduce interference with people outside the vehicle. For example, under bright light conditions (such as during the day), for areas where images need to be displayed, the light cutoff area can be switched to a dark state to avoid interference from ambient light outside the vehicle, thereby providing images with higher contrast; under dim light conditions (such as at night or on rainy days), the light cutoff area switched to a dark state provides a high-contrast image while also providing privacy protection for the displayed image content and reducing interference with people outside the vehicle.When the light-cutting layer is switched to a non-dark state as required, the visible light transmittance of the light-cutting layer can be greater than or equal to 50%, greater than or equal to 60%, greater than or equal to 70%, greater than or equal to 80%, or the highest transmittance of the light-cutting layer, thereby meeting the different perspective requirements of the vehicle interior personnel on the vehicle exterior. When applied to display images to the exterior of the vehicle, the glass assembly of the present disclosure can also similarly provide an enhanced image display to the exterior of the vehicle and avoid interference with the personnel inside the vehicle.

[0058] Preferably, the haze of the selected orthographic projection display layer itself is lower than 10%, preferably, lower than 5%, the diffuse reflectance of visible light is greater than or equal to 10%, and the transmittance of visible light can be greater than or equal to 70%. For the orthographic projection display layer using the holographic projection mode, the transmittance of visible light can also be greater than or equal to 70%. In this article, haze is the ratio of the scattered light flux of the incident light that deviates from the normal direction through the sample to the transmitted light flux, expressed in %. Usually, only the scattered light flux that deviates from the direction of the incident light by more than 2.5 degrees is used to calculate the haze, and a haze meter is used to measure it according to standards GB2410 and ASTM D1003. The transmittance of visible light is the light transmittance in the visible spectrum region, expressed in %, and measured according to standard ISO 9050:2003 (light source D65; 2° observer). Diffuse reflectance refers to the ratio of the total amount of diffuse reflected light to the total amount of incident light, expressed in %, and measured via the SCE (Specular Component Exclude, excluding specular reflected light) measurement mode.

[0059] Advantageously, the light-cutting layer has a high contrast ratio between its highest light transmittance and its lowest light transmittance, where "contrast ratio" refers to the measurement of different brightness levels between the brightest white and the darkest black in the light and dark areas of an image, and a larger difference range represents a greater contrast ratio, and a smaller difference range represents a smaller contrast ratio. Alternatively, the light-cutting layer may be a film layer having a contrast ratio greater than or equal to 10:1, for example, the light-cutting layer may be configured as any one of a suspended particle (SPD) film layer, an electrochromic (EC) film layer, a dye-doped polymer dispersed liquid crystal (DDPDLC) film layer, a guest-host liquid crystal (GHLC) film layer, and an electrophoretic film layer.

[0060] Particularly advantageously, each of the multiple light-cutting regions of the light-cutting layer is configured to be switchable between a non-dark state and a dark state, because the user has a demand for providing projection in a specific region or a local region of the glass component. For example, when the glass component is applied to a door glass, through the study of ergonomics, the driver or passenger has a more frequent projection demand for an ergonomically (for example, a region on the door glass that is relatively closer to the front of the vehicle) area of ​​the door glass (for example, an area on the door glass that is relatively closer to the front of the vehicle) area (for example, an area that is relatively closer to the front of the vehicle). By providing a sub-regional light-cutting layer combined with sub-regional projection, the light-cutting region switched to a dark state can provide an image display effect with enhanced contrast and / or a privacy effect of the image content, and the light-cutting region in a non-dark state can meet the driver's or passenger's perspective demand for the outside of the vehicle, ensuring a good observation field of the driver and passenger to the outside of the vehicle, and improving driving safety and driving experience. It is also possible to provide functional requirements for adapting to more occasions and various weather conditions through this partition design combined with the free and stepless adjustment of light transmittance.

[0061] It should be understood that the glass assembly of the present disclosure encompasses a single glass body and a laminated glass having multiple glass bodies. Figure 1 A glass assembly 100 of an embodiment is exemplarily shown, comprising a first glass body 110 and a second glass body 120, and an adhesive layer attaching the first glass body 110 and the second glass body 120 to each other. Specifically, the adhesive layer comprises a first adhesive layer 130a attached to the first glass body 110 and a second adhesive layer 130b attached to the second glass body 120. In addition, the orthographic projection display layer 140 may be arranged on the surface of the second glass body 120 away from the first glass body 110, for example, through a third adhesive layer 130c, for displaying an image to one side of the glass assembly 100. When the orthographic projection display layer 140 adopts a projection film with a back adhesive, the third adhesive layer 130c may be regarded as being integral with the orthographic projection display layer 140. As described above, the light-cutting layer of the present disclosure is arranged on the opposite side of the display image of the orthographic projection display layer. Depending on the arrangement of the orthographic projection display layer, the light-cutting layer may be arranged on the surface of the first glass body away from the second glass body, or on the surface of the second glass body away from the first glass body, or sandwiched between the first glass body and the second glass body. For example Figure 1 In the illustrated embodiment, the light-cutting layer 150 is sandwiched between the first glass body 110 and the second glass body 120, specifically, the light-cutting layer 150 is sandwiched between the first adhesive layer 130a and the second adhesive layer 130b. It should be understood that the orthographic display layer 140 and the light-cutting layer 150 are shown in the figure as having substantially the same length or width as the first glass body 110 and the second glass body 120. When the orthographic display layer 140 and / or the light-cutting layer 150 cover a portion of the first glass body 110 and the second glass body 120, for example Figure 1One of the first adhesive layer 130a and the second adhesive layer 130b attached to the light-cutting layer 150 can be omitted, and the light-cutting layer 150 is surrounded by the other of the first adhesive layer 130a and the second adhesive layer 130b. The light-cutting layer 150 includes a plurality of light-cutting regions, and three light-cutting regions are exemplarily shown in the figure, namely, the first light-cutting region 150a, the second light-cutting region 150b and the third light-cutting region 150c. It should be understood that the number of light-cutting regions can also be selected as two or more than three according to different needs, for example, four, five, six, etc. In addition, although the light-cutting layer is divided into a plurality of light-cutting regions, the intervals between the plurality of light-cutting regions are less than or equal to 0.1 mm, so that the gaps are invisible to the naked eye and ensure aesthetics.

[0062] In different embodiments, the orthographic projection display layer 140 may be arranged on a surface of the first glass body 110 away from the second glass body 120, or sandwiched between the first glass body 110 and the second glass body 120. Here, "between" covers various arrangements in which the orthographic projection display layer 140 is directly adjacent to or not directly adjacent to the first glass body 110 or the second glass body 120, for example, Figure 1 The orthographic projection display layer 140 in the illustrated embodiment may also be arranged between the second adhesive layer 130b and the second glass body 120, or arranged between the first adhesive layer 130a and the second adhesive layer 130b and adjacent to the light interception layer 150. Of course, depending on the arrangement position of the projection device, the effect of displaying images toward different sides of the glass assembly 100 can be obtained through the orthographic projection display layer 140. For example, when the glass assembly 100 is applied to a vehicle-mounted projection system, the first glass body 110 may face the outside of the vehicle (may be referred to as the outer glass), the second glass body 120 may face the inside of the vehicle (may be referred to as the inner glass), and the orthographic projection display layer 140 may be configured to display images toward the inside of the vehicle. Accordingly, the projection device in the vehicle-mounted projection system may be arranged inside the vehicle so that the orthographic projection display layer 140 specifically faces the inside of the vehicle. Figure 1 In this way, according to different needs, one or more of the multiple light-cutting regions of the light-cutting layer 150 can be switched to a dark state, so that the corresponding part of the orthographic projection display layer 140 provides an image display effect with enhanced contrast, provides a privacy effect of the image content, and reduces the impact on people outside the vehicle, while maintaining the light-cutting region in a non-dark state, for example, to meet the viewing field requirements of the driver or passenger.

[0063] The first adhesive layer 130a, the second adhesive layer 130b and the third adhesive layer 130c are adhesive layers suitable for laminated glass, such as polyvinyl butyral (PVB), ethylene vinyl acetate copolymer (EVA), and optically clear adhesive (OCA).

[0064] Figure 2 In the glass assembly 100 - 1 of another embodiment shown in the exemplary embodiment, the adhesive layer includes a first adhesive layer 130 a attached to the first glass body 110 and a second adhesive layer 130 b attached to the second glass body 120 . Figure 1 The embodiment shown is different in that the light-cutting layer including the first light-cutting region 150a, the second light-cutting region 150b and the third light-cutting region 150c and the front projection display layer 140 are all sandwiched between the first adhesive layer 130a and the second adhesive layer 130b. Specifically, the light-cutting layer is sandwiched between the first adhesive layer 130a and the third adhesive layer 130c, and the front projection display layer 140 is sandwiched between the third adhesive layer 130c and the second adhesive layer 130b. Similarly, when the front projection display layer 140 adopts a projection film with a backing adhesive, any one of the third adhesive layer 130c and the second adhesive layer 130b can be regarded as being integrated with the front projection display layer 140. Similarly, when the forward projection display layer 140 and / or the light-cutting layer 150 cover parts of the first glass body 110 and the second glass body 120, one of the two adjacent adhesive layers can be omitted and the forward projection display layer 140 and / or the light-cutting layer 150 can be surrounded by the other of the two adhesive layers.

[0065] Figure 3 In the glass assembly 100-2 of another embodiment shown in the example, the light-cutting layer and the orthographic projection display layer 140 including the first light-cutting region 150a, the second light-cutting region 150b and the third light-cutting region 150c are both sandwiched between the first adhesive layer 130a and the second adhesive layer 130b, and separated by the third adhesive layer 130c. Similarly, one of the two adhesive layers adjacent to the orthographic projection display layer 140 can be regarded as being integral with the orthographic projection display layer 140. Similarly, one of the two adhesive layers adjacent to the orthographic projection display layer 140 and / or the light-cutting layer 150 can be omitted, and the orthographic projection display layer 140 and / or the light-cutting layer 150 can be surrounded by the other of the two adhesive layers, which will not be described in detail here.

[0066] In some embodiments, the glass assembly may further include a picture frame structure arranged around the orthographic projection display layer 140 and / or the light intercepting layer 150. Figure 2 The embodiment shown differs in that Figure 3The picture frame structure 170 arranged around the front projection display layer 140 and the light interception layer 150 is exemplarily shown. The picture frame structure 170 can realize pre-positioning of the front projection display layer 140 and the light interception layer 150, fill the thickness difference between the edges of the front projection display layer 140 and the light interception layer 150 and the adhesive layer, and ensure complete sealing after lamination. Alternatively, the picture frame structure can be selected to be the same material as the adhesive layer. In the case where the thickness of the front projection display layer 140 and / or the light interception layer is small enough, the picture frame structure can also be omitted.

[0067] In some embodiments, the glass component may further include a functional layer such as a touch layer, which will not be described in detail herein.

[0068] In some embodiments, the light-cutting layer 150 substantially covers the entire front projection display layer 140 along the surface direction of the glass component. Here, "substantially" means that the area of ​​the light-cutting layer along the surface direction of the glass component is consistent with the area of ​​the front projection display layer, or the area of ​​the light-cutting layer is slightly larger than the area of ​​the front projection display layer, such as Figure 3 As exemplified, the edge of the light intercepting layer may exceed the edge of the front projection display layer by more than 1 mm, preferably by 1 to 5 mm, for example, by 3 mm, so as to ensure the above-mentioned effects required for the glass component.

[0069] Figure 4 The embodiment in which the light intercepting layer 150 substantially covers the entire front projection display layer 140 is exemplarily shown. Figure 4 The first light-truncation region 150a, the second light-truncation region 150b, and the third light-truncation region 150c of the orthographic projection display layer 140 and the light-truncation layer 150 are all shown as roughly rectangular shapes. Under the premise of meeting the concept of the present disclosure, the orthographic projection display layer and the light-truncation region herein include any appropriate shapes, including but not limited to squares, triangles, sectors, other figures with arc-shaped edges or straight edges, etc. It should be understood that light-truncation regions of different shapes or sizes and / or different numbers of light-truncation regions and / or the size of the light-truncation region covering the orthographic projection display layer can be determined according to the shape or size of the area where the image needs to be displayed and / or the shape or size of the area where the corresponding effect needs to be provided.

[0070] When the glass component is applied as, for example, a front windshield, a rear windshield or a corner window glass, the glass component is suitable for cooperating with a sealing strip when the glass component is installed in the vehicle and in a fully used state of the glass component. When the glass component is configured as a door glass, the glass component is suitable for cooperating with a water-cut strip (also a sealing strip) when the glass component is installed in the vehicle and in a fully used state of the glass component (i.e., when the door glass window is fully closed), for example Figures 5 to 7The water cut strip 180 is shown as an example. The water cut strip refers to a rubber sealing strip between the door glass and the door frame at the lower part of the door glass, which is used to cut off water droplets, water mist and dust on the glass surface when the door glass is raised or lowered, and also plays an aesthetic role.

[0071] The projection system of the present disclosure comprises a projection device and any of the above-mentioned glass components, wherein the projection device corresponds to the positive projection display layer of the glass component. The present disclosure also provides a projection device, which is configured to project an image onto any of the above-mentioned glass components.

[0072] In some embodiments, the glass assembly includes a control unit, the control unit being configured to: obtain an instruction of a region for a projection device to project an image on a front projection display layer, or determine a region for a projection device to project an image on the front projection display layer; cause the projection device to project an image on the region for projecting an image on the front projection display layer; in response to the projection device projecting an image on the region for projecting an image on the front projection display layer, cause at least one light-truncation region of the light-truncation layer corresponding to the region for projecting an image on the front projection display layer to be in a dark state. Optionally, the control unit includes at least one of a vehicle control unit, a remote control unit, an electronic control unit of a projection device, and an electronic control unit of a light-truncation layer.

[0073] In some embodiments, the glass assembly may include a human-machine interaction unit, the control unit at least includes an electronic control unit of the human-machine interaction unit, and the electronic control unit of the human-machine interaction unit is configured to determine the area where the projection device projects an image on the positive projection display layer. Optionally, the control unit also includes at least one of a vehicle control unit, a remote control unit, an electronic control unit of the projection device, and an electronic control unit of the light interception layer.

[0074] In some embodiments, the projection device includes a control unit, the control unit being configured to: obtain an instruction for the projection device to project an image on the front projection display layer, or determine the area on the front projection display layer where the projection device projects an image; cause the projection device to project an image on the area on the front projection display layer where the image is projected; in response to the projection device projecting an image on the area on the front projection display layer where the image is projected, cause at least one light-truncation area of ​​the light-truncation layer of the glass component corresponding to the area on the front projection display layer where the image is projected to be in a dark state. Optionally, the control unit includes at least one of a vehicle control unit, a remote control unit, an electronic control unit of the projection device, and an electronic control unit of the light-truncation layer.

[0075] In some embodiments, the projection device may include a human-machine interaction unit, the control unit at least includes an electronic control unit of the human-machine interaction unit, and the electronic control unit of the human-machine interaction unit is configured to determine the area where the projection device projects an image on the positive projection display layer of the glass assembly. Optionally, the control unit also includes at least one of a vehicle control unit, a remote control unit, an electronic control unit of the projection device, and an electronic control unit of the light interception layer.

[0076] In the case where the glass component and / or the projection device includes a human-computer interaction unit, the human-computer interaction unit can be connected to the glass component and / or the projection device through an external interface and / or a wireless transceiver. Optionally, the human-computer interaction unit includes at least one of a key module, a touch module, a gesture module, and a voice module.

[0077] Figures 5 to 7 The examples respectively illustrate the case where any of the above-mentioned glass assemblies are applied to vehicle door glass, and a projection device (not shown) may be arranged inside the vehicle to display a projected image through the glass assembly toward the inside of the vehicle.

[0078] See first Figure 5 , the glass assembly 100 is usually placed in a substantially vertical direction after being installed in the vehicle, and the arrow in the figure indicates the direction toward the head of the vehicle, that is, the first light interception area 150a, the second light interception area 150b and the third light interception area 150c are arranged in sequence from the front of the vehicle to the rear of the vehicle. In this embodiment, the first light interception area 150a is switched to a dark state, and the image 190 projected by the projection device can be clearly displayed on the corresponding part of the positive projection display layer 140, and the displayed image has an enhanced contrast or clarity, which improves the image display effect. Figure 6 In the illustrated embodiment, the first light-intercepting region 150 a and the second light-intercepting region 150 b are switched to a dark state, and the corresponding portion of the image 190 displayed by the forward projection display layer 140 increases accordingly. Figure 7In the illustrated embodiment, the first light-cutoff region 150a, the second light-cutoff region 150b, and the third light-cutoff region 150c are switched to a dark state, that is, substantially the entire orthographic projection display layer 140 can be used to display the image 190, which can be applied to, for example, the rear door glass, or the front door glass in a non-driving state, or the front door glass with an in-vehicle electronic rearview mirror installed. In this way, in some cases, the image 190 can be projected and displayed only in the area of ​​the door glass close to the front of the vehicle, so as to meet the needs of the driver and passengers to observe the image with an ergonomic design, while keeping the remaining area of ​​the door glass in a non-dark state to meet the needs of the driver and passengers to observe the outside of the vehicle. When the light-cutoff region is switched to a dark state, not only the contrast or clarity of the image is enhanced, but also the privacy protection of the image content can be provided and the impact on people outside the vehicle can be reduced.

[0079] According to different needs, each light-cutoff area can be controlled separately, so that, for example, it can cooperate with the projection device to realize various adjustment functions such as segmented display, dynamic display, and flow display, so as to meet the different functional needs of users. In some embodiments, relative to at least one of the multiple light-cutoff areas of the light-cutoff layer of the glass component, the projection device is configured to be able to project an image on (that is, only on) the portion of the positive projection display layer corresponding to the at least one light-cutoff area. More specifically, relative to each light-cutoff area, the projection device is configured to be able to project an image on (that is, only on) the portion of the positive projection display layer corresponding to each light-cutoff area. For example, by using an optical baffle or an optical lens, etc., the projected image is only projected on Figure 5 The first light interception region 150a or Figure 6 The first light interception area 150a and the second light interception area 150b are displayed. The projection device may include one or more projectors, which are used as needed and are not described in detail here.

[0080] In some embodiments, the projection system includes a control unit, and the control unit is configured to: obtain an instruction of the area where the projection device projects an image on the front projection display layer, or determine the area where the projection device projects an image on the front projection display layer; make the projection device project an image on the area where the image is projected on the front projection display layer; in response to the projection device projecting an image on the area where the image is projected on the front projection display layer, make at least one light-cutoff area of ​​the light-cutoff layer corresponding to the area where the image is projected on the front projection display layer in a dark state. For example, when the projection device projects an image onto a certain part of the front projection display layer, the light-cutoff area corresponding thereto will switch to a dark state, and when a certain part of the front projection display layer no longer has a projected image, the light-cutoff area corresponding thereto can be switched to a non-dark state as needed, for example, to provide a clear observation field of view, or remain in a dark state to meet the specific needs of the user. Alternatively, the control unit includes at least one of a vehicle control unit, a remote control unit, an electronic control unit of the projection device, and an electronic control unit of the light-cutoff layer. It should be understood that the control unit here may include independent control units separated in different physical locations, or may include an integrated control unit integrated in the same physical location.

[0081] In some embodiments, the projection system may include a human-machine interaction unit, the control unit at least includes an electronic control unit of the human-machine interaction unit, and the electronic control unit of the human-machine interaction unit is configured to determine the area where the projection device projects an image on the positive projection display layer of the glass component. In this case, the control unit may also include at least one of a vehicle control unit, a remote control unit, an electronic control unit of the projection device, and an electronic control unit of the light interception layer. Alternatively, the human-machine interaction unit may be connected to the glass component and / or the projection device through an external interface and / or a wireless transceiver. In this way, when applied to a vehicle-mounted projection system, the vehicle-mounted projection system can be integrated into a comprehensive control system in combination with the human-machine interaction unit, such as an automatic driving system (ADAS), thereby providing a richer and more diversified functional mode and improving the driving experience of the driver and passengers. In some optional embodiments, the human-machine interaction unit may include at least one of a key module, a touch module, a gesture module, and a voice module. Alternatively, the glass component may have an adapted functional layer to achieve human-machine interaction, such as a touch layer. Furthermore, in certain embodiments, in addition to the human-computer interaction method, the vehicle-mounted projection system of the present disclosure may also, for example, according to the vehicle's operating mode (e.g., starting, accelerating, constant speed, decelerating, turning, uphill and downhill, parking, etc.), correspondingly enable the projection device to project an image onto the orthographic display layer of the glass component through, for example, a control unit.

[0082] Regardless of the arrangement and combination, the glass assembly of the present disclosure advantageously provides the image display function of enhancing contrast, the privacy function of the image content on the image display side, and the function of reducing adverse effects on the non-image display side according to different needs, bringing users a rich and comfortable use experience. It should be understood that in the possible implementation methods described or not described, various improvements can be used independently or in combination with each other, so that the glass assembly and projection system of the present disclosure can be applied to a variety of occasions to meet the diverse needs of users.
