Background Technology

[0002] With the rapid development of the automotive industry, car windows, as an excellent medium for transmitting information to the interior and / or exterior of vehicles, have received widespread attention from vehicle manufacturers and are favored by consumers. Compared to using other in-vehicle locations for displays (such as displays on the back of the seats), car windows offer greater convenience, larger usable area, greater durability, and a better user experience. For example, projection film can be applied to the rear windshield of taxis to display advertising content such as images or videos to the exterior of the vehicle.

[0003] While projecting images onto the outside of a vehicle through its windows can satisfy some consumer needs, vehicle manufacturers and consumers expect to provide a more diverse experience through car windows. Summary of the Invention

[0053] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed are merely illustrative of particular ways of implementing and using this disclosure, and are not intended to limit the scope of this disclosure. The descriptions of the structural positions of various components, such as up, down, top, bottom, etc., are not absolute but relative. These directional descriptions are appropriate when the various components are arranged as shown in the figures, but they change accordingly when the positions of the various components in the figures change.

[0054] In this document, expressions such as “including” or similar expressions such as “having” are open-ended and do not exclude additional unlisted elements, steps or components.

[0055] In this document, the terms “first”, “second”, etc., are not used to specify the order of events or the number of components, unless otherwise stated.

[0056] In this document, unless otherwise explicitly specified, the terms "attachment" and similar terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this document according to the specific circumstances.

[0057] In this article, "multiple" means two or more, unless otherwise explicitly specified.

[0058] In this article, the "surface" of a glass body or stacked layer structure refers to the surface with a large surface area among the various faces of the glass body or stacked layer structure, and the "edge" refers to the surface of the glass body or stacked layer structure defined by its thickness. The "section" of a glass assembly is a section taken along the thickness direction of the glass assembly, and the "section direction" is the direction perpendicular to the surface of the glass body or the normal direction of the surface of the glass body.

[0059] In this document, the glass assembly is described as being used in automotive window glass; however, it is not excluded that the glass assembly can be used in environments such as doors, windows, curtain walls, aircraft glass, or ship glass. When the glass assembly is described as being used in automotive window glass, "outer" and "inner" are directions relative to the vehicle body; "outer" refers to the direction away from the vehicle body, and "inner" refers to the direction facing the vehicle body; "vertical direction" refers to the direction approximately perpendicular to the ground. It should be understood that the automotive window glass according to embodiments of this disclosure includes, but is not limited to, windshields, rear windshields, door glass (including front door glass and rear door glass), or corner window glass, and can provide different image display effects based on different needs.

[0060] 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 the various layers on the glass is within a conventional range and is not limited to what is shown in the figures. Furthermore, although the figures show flat glass, the glass assembly of this disclosure can also be curved glass. In the various embodiments, each is described as a separate glass body; however, in some cases not described, the surface of the glass body may also be coated with special coatings to improve thermal insulation and / or other properties such as comfort.

[0061] For manufacturers and most vehicle users, there is a desire to utilize vehicle windows to achieve various forms of image display effects. These include displaying images into the vehicle while providing privacy and minimizing impact on people outside the vehicle; selectively displaying images to the outside; or displaying images both inside and outside the vehicle simultaneously, such as displaying welcome or warning messages to people or vehicles outside the vehicle to facilitate information interaction between the inside and outside. This places more diverse design requirements on vehicle windows. It is recognized that in cases where images are projected into the vehicle through the window, drivers and passengers tend to be interested in certain areas of the image displayed. For example, drivers and passengers prefer display areas with smaller head rotation angles, such as the area on the door glass relatively closer to the front of the vehicle. Similarly, in cases where images are projected outwards, it is desirable that the displayed image not adversely affect the driver; for example, the area on the door glass displaying images outwards should be relatively closer to the rear of the vehicle.

[0062] In this article, "privacy" refers to the privacy of vehicle occupants. Specifically, in situations where images are displayed inside the vehicle, the vehicle windows must prevent outsiders from clearly seeing the displayed content, thus achieving privacy protection. The displayed images are not limited in this article; they can be static text, numbers, symbols, or images, or they can be dynamic videos.

[0063] According to the concept of this disclosure, a glass assembly is provided, the glass assembly comprising: a glass body; an active display layer disposed on the surface of the glass body for displaying images, the active display layer comprising one or more active display layers; and a light cutoff layer comprising a plurality of light cutoff regions, each light cutoff region being configured to switch between a non-dark state and a dark state, the light cutoff layer comprising one or more light cutoff layers, wherein each light cutoff region corresponds at least partially to the active display layer.

[0064] The image display function provided by the active display layer in the glass assembly of this disclosure, depending on different needs, can cover displaying images to the exterior and / or interior of the vehicle, using the above-described solution of this disclosure. Furthermore, the glass assembly of this disclosure includes a light-blocking layer comprising multiple light-blocking regions. Depending on different needs, one or more light-blocking layers may be arranged on either side or both sides of at least one active display layer, or one or more active display layers may be arranged on either side or both sides of at least one light-blocking layer. It should be understood that, in the following description, unless otherwise expressly stated, a light-blocking layer includes one or more light-blocking layers, and an active display layer includes one or more active display layers. In this document, "active display" refers to the ability to display images by emitting light itself when powered on, without requiring a light source. "Light blocking" refers to the ability of the light-blocking region to block light when in a dark state, preventing light from being transmitted through the light-blocking layer; the light-blocking layer may also be referred to as a light valve. Here, "dark state" refers to a state in which the visible light transmittance of the light-cutting region 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 the lowest transmittance of the light-cutting region (e.g., 0.5%). "Non-dark state" refers to a state in which the visible light transmittance of the light-cutting region is greater than the visible light transmittance in the dark state. For example, when the light-cutting region is in the non-dark state, the visible light transmittance of the light-cutting region can 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 the highest transmittance of the light-cutting region. Optionally, when the light-blocking region is in a dark state, the visible light transmittance of the glass component in the cross-sectional direction is less than or equal to 10%, less than or equal to 5%, less than or equal to 4%, less than or equal to 3%, less than or equal to 2%, and less than or equal to 1%; when the light-blocking region is in a non-dark state, the visible light transmittance of the glass component in the cross-sectional direction is 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%, and greater than or equal to 80%. The visible light transmittance when the light-blocking region is in a non-dark state is greater than the visible light transmittance when the light-blocking region is in a dark state, and the difference between the two is, for example, greater than or equal to 5%, greater than or equal to 10%, greater than or equal to 15%, greater than or equal to 20%, greater than or equal to 25%, 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%, and greater than or equal to 80%. In this paper, the transmittance of visible light is the transmission of light in the visible spectrum region, expressed as a percentage, and measured according to standard ISO 9050:2003 (light source D65; 2° observer).

[0065] According to this disclosure, the non-dark state of the light-cutting region can encompass one or more stable states corresponding to different visible light transmittances, such as two, three, four, five, or more. Thus, depending on different needs, the transmittance can be freely and infinitely adjusted within the defined range of different maximum transmittances of the light-cutting regions of the selected different forms of light-cutting layers. The light-cutting region in the dark state can cut off the light from the displayed image from the active display layer, thereby improving the contrast of the image on the opposite side and enhancing the clarity of the image displayed on the active display layer. When applied, for example, to vehicle door glass and displaying images inside the vehicle, the glass assembly of this disclosure not only allows occupants inside the vehicle to observe the enhanced displayed image but also achieves privacy protection for the displayed image content and reduces interference to people outside the vehicle. For example, under bright lighting conditions (e.g., during the day), for areas where images need to be displayed, the corresponding light-blocking area on the side of the active display layer facing the outside of the vehicle can be switched to a dark state to avoid interference from ambient light from outside the vehicle, thereby providing an image with higher contrast. Under dim lighting conditions (e.g., at night or on rainy days), the light-blocking area switched to a dark state provides a high-contrast image while also providing privacy protection for the displayed image content and reducing interference to people outside the vehicle. When applied, for example, to door glass and displaying images to the outside of the vehicle, the glass assembly of this disclosure not only allows people outside the vehicle to observe the enhanced display image but also reduces or avoids interference to people inside the vehicle. When the light-blocking area is switched to a non-dark state, the visible light transmittance of the light-blocking area 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-blocking area, thereby meeting the different perspective needs of people inside the vehicle to see the outside of the vehicle, or not affecting the needs of people inside and / or outside the vehicle to observe the images displayed by the active display layer.

[0066] Advantageously, the active display layer is a transparent active display layer, meaning it has high visible light transmittance, which is beneficial for applications in glass components. However, the use of active display layers with relatively low visible light transmittance, resulting in a relatively non-transparent appearance, is not excluded. Preferably, the active display layer includes a micro-light-emitting diode (Micro-LED or μLED) display layer or an organic light-emitting diode (OLED) display layer. OLED is a device that uses a multilayer organic thin-film structure to generate electroluminescence, featuring thinness, high brightness, low power consumption, fast response, high resolution, good flexibility, and high luminous efficiency. Micro-LED is a display technology that integrates micron-sized semiconductor light-emitting diodes (LEDs) in a matrix on a single chip with high density, offering advantages such as high brightness, high resolution, low power consumption, and high reliability. Due to the self-emissive nature of OLEDs or Micro-LEDs, they can achieve transparent and flexible display effects while being thinner and lighter, making them suitable for various applications in glass components.

[0067] When applied to automotive windows, advantageously, the selected active display layer itself has a haze of less than 10%, preferably less than 5%, and for different types of windows, the visible light transmittance can be greater than or equal to 50% (e.g., rear door windows). Herein, haze is expressed as a percentage (%), representing the ratio of scattered luminous flux to transmitted luminous flux of incident light deviating from the normal direction. Typically, only scattered luminous flux deviating more than 2.5 degrees from the incident light direction is used to calculate haze, and it is measured using a haze meter according to standards GB2410 and ASTM D1003.

[0068] Advantageously, the light-cutting region of the light-cutting layer has a high contrast between its highest and lowest transmittance, where "contrast" refers to the ratio between the highest and lowest transmittance. Alternatively, the light-cutting layer can be a film layer with a contrast ratio greater than or equal to 10:1, but it should be understood that it is not necessarily greater than or equal to 10:1. For example, the light-cutting layer can 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, or an electrophoretic film layer. In specific embodiments, the multiple light-cutting regions of the light-cutting layer can be configured as the same or different film layers, such as any combination of the film layers listed above.

[0069] According to this disclosure, the multiple light-cutting regions of the light-cutting layer are each configured to switch between a non-dark state and a dark state. This is because users have a need for image display in specific or localized areas of the glass assembly. For example, when the glass assembly is used in vehicle door glass, through ergonomic studies, drivers or passengers have a more frequent need for image display in ergonomically designed areas of the door glass (e.g., areas closer to the front of the vehicle) or tend to display more important information in these areas. By providing a zoned light-cutting layer, the light-cutting region switching to the dark state can provide an image display effect with enhanced contrast and / or privacy of the image content, while the light-cutting region in the non-dark state can meet the driver's or passenger's need for visibility to the outside of the vehicle, ensuring a good field of vision for the driver and passengers, and improving driving safety and the driving experience. Furthermore, this zoned design, combined with the free and stepless adjustment of light transmittance, can provide functionality to adapt to more occasions and various weather conditions.

[0070] It should be understood that the glass components disclosed herein encompass single-layer glass and laminated glass having multiple layers of glass. Figure 1 An exemplary embodiment of a laminated glass assembly 100 includes 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 includes 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 different embodiments, at least one active display layer may be disposed on a surface of the first glass body 110 away from the second glass body 120, or at least one active display layer may be disposed on a surface of the second glass body 120 away from the first glass body 110, or at least one active display layer may be sandwiched between the first glass body 110 and the second glass body 120. Here, "between" encompasses various arrangements in which at least one active display layer is directly adjacent to or not directly adjacent to the first glass body 110 or the second glass body 120. Figure 1 In the illustrated embodiment, taking an active display layer 140 as an example, the active display layer 140 can be disposed, for example, on the surface of the second glass body 120 away from the first glass body 110 via a third adhesive layer 130c. Since an active display layer is used, and preferably a transparent active display layer, depending on different needs, at least one light-blocking layer can be disposed on either side of the active display layer 140. For example, at least one light-blocking layer can be disposed 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 and second glass bodies. For example... Figure 1In the illustrated embodiment, taking a light-blocking layer 150 as an example, the light-blocking layer 150 is sandwiched between the first glass body 110 and the second glass body 120. Specifically, the light-blocking layer 150 is sandwiched between the first adhesive layer 130a and the second adhesive layer 130b. It should be understood that, based on different needs, light-blocking layers can also be arranged on both sides of the active display layer, which will be further described below in conjunction with specific embodiments.

[0071] exist Figure 1 In the illustrated embodiment, the light-blocking layer 150 covers or substantially covers the entire active display layer 140 along the cross-sectional direction of the glass bodies (first glass body 110 and second glass body 120). Here, "covers" means that the orthographic projection of the light-blocking layer along the cross-sectional direction of the glass body covers the orthographic projection of the active display layer. "Substantially covers" means that the size or area of ​​the orthographic projection of the light-blocking layer along the cross-sectional direction of the glass body (or glass assembly) is approximately equal to the size or area of ​​the orthographic projection of the active display layer. That is, the size or area of ​​the orthographic projection of the light-blocking layer is consistent with the size or area of ​​the orthographic projection of the active display layer, or the size or area of ​​the orthographic projection of the light-blocking layer is slightly larger or slightly smaller, preferably slightly larger than the size or area of ​​the orthographic projection of the active display layer. For example, the edge of the light-blocking layer 150 may extend beyond the edge of the active display layer 140 by more than 1 mm, preferably by 1 mm to 5 mm, for example, 3 mm, thereby ensuring the aforementioned effect required by the glass assembly. Furthermore, when the active display layer 140 and / or the light-blocking layer 150 cover a portion of the first glass body 110 and the second glass body 120, for example... Figure 1 One 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. Here, "surrounding" means that the edge of the light-cutting layer is covered by the adhesive layer on one side of the light-cutting layer, thereby sandwiching the entire light-cutting layer between the first glass body 110 and the second glass body 120.

[0072] According to this disclosure, the optical cutoff layer may include a plurality of optical cutoff regions corresponding to at least a portion of an active display layer, or the optical cutoff layer may include one or more optical cutoff regions corresponding to at least a portion of each of a plurality of active display layers. Figure 1The example illustrates three light-cutting regions corresponding to at least a portion of the active display layer 140: a first light-cutting region 150a, a second light-cutting region 150b, and a third light-cutting region 150c. It should be understood that the number of light-cutting regions can also be selected as two or more, for example, four, five, six, etc., depending on different needs. Furthermore, although a light-cutting layer is divided into multiple light-cutting regions, the interval between the multiple light-cutting regions in a light-cutting layer can be less than or equal to 0.5 mm, less than or equal to 0.4 mm, less than or equal to 0.3 mm, less than or equal to 0.2 mm, or less than or equal to 0.1 mm. When the interval is, for example, less than or equal to 0.1 mm, the gap can be made invisible to the naked eye, ensuring aesthetics.

[0073] In different embodiments, the active display layer 140 may also be disposed on the 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. For example, Figure 1 In the illustrated embodiment, the active display layer 140 can also be arranged between the second adhesive layer 130b and the second glass body 120, or between the first adhesive layer 130a and the second adhesive layer 130b adjacent to the light-blocking layer 150. Depending on the different arrangement positions of the active display layer 140 and the light-blocking layer 150, the active display layer 140 can achieve the effect of displaying images to different sides of the glass assembly 100. For example, when the glass assembly 100 is applied to a vehicle window, the first glass body 110 can face the outside of the vehicle (which may be referred to as the outer glass), and the second glass body 120 can face the inside of the vehicle (which may be referred to as the inner glass). Thus, according to different needs, one or more light-blocking regions of the multiple light-blocking regions of the light-blocking layer 150 can be switched to a dark state or a non-dark state, so that corresponding portions of the active display layer 140 in different arrangement positions can display images to the inside and / or outside of the vehicle. Figure 1 In this configuration, when one or more light-blocking regions switch to a dark state, the corresponding portion of the active display layer 140 can provide an enhanced contrast image display effect to the vehicle interior while maintaining privacy for the interior image content and reducing the impact on people outside the vehicle; alternatively, when one or more light-blocking regions switch to a non-dark state, the non-dark light-blocking regions do not adversely affect the image display effect provided by the corresponding portion of the active display layer 140. In various applications, maintaining the non-dark light-blocking regions can, for example, meet the viewing field requirements of the driver or passengers.

[0074] As an example, the first adhesive layer 130a, the second adhesive layer 130b, and the third adhesive layer 130c are, for example, adhesive layers suitable for laminated glass such as polyvinyl butyral (PVB), ethylene-vinyl acetate copolymer (EVA), and optically clear adhesive (OCA).

[0075] Figure 2 In another exemplary embodiment of the glass assembly 100-1, the adhesive layer includes a first adhesive layer 130a attached to a first glass body 110 and a second adhesive layer 130b attached to a second glass body 120. Figure 1 The illustrated embodiment differs in that at least one light-blocking layer and at least one active display layer are sandwiched between the first adhesive layer 130a and the second adhesive layer 130b. Specifically, a light-blocking layer comprising a first light-blocking region 150a, a second light-blocking region 150b, and a third light-blocking region 150c is sandwiched between the first adhesive layer 130a and the third adhesive layer 130c, and an active display layer 140 is sandwiched between the third adhesive layer 130c and the second adhesive layer 130b. That is, the active display layer 140 is closer to the second glass body 120 than the light-blocking layer, for example, closer to the inner glass when applied to a car window. Similarly, when the active display layer 140 and / or the light-blocking layer 150 cover a portion of the first glass body 110 and the second glass body 120, one of the two adjacent adhesive layers can be omitted, and the active display layer 140 and / or the light-blocking layer 150 can be surrounded by the other of the two adhesive layers.

[0076] Figure 3 In another exemplary embodiment of the glass assembly 100-2, a light-blocking layer including a first light-blocking region 150a, a second light-blocking region 150b, and a third light-blocking region 150c, and an active display layer 140 are both sandwiched between the first adhesive layer 130a and the second adhesive layer 130b, and spaced apart by the third adhesive layer 130c. Figure 2 The difference in the illustrated embodiment is that the active display layer 140 is closer to the first glass body 110 than the light-blocking layer 150, for example, closer to the outer glass when applied to a vehicle window. Similarly, when the active display layer 140 and / or the light-blocking layer 150 cover a portion of the first glass body 110 and the second glass body 120, one of the two adhesive layers adjacent to the active display layer 140 and / or the light-blocking layer 150 can be omitted, and the active display layer 140 and / or the light-blocking layer 150 can be surrounded by the other of the two adhesive layers, which will not be elaborated here.

[0077] In some embodiments, the glass assembly may also include a frame structure arranged around at least one active display layer and / or at least one light-blocking layer. For example, with Figure 2 The difference in the implementation method shown is that, Figure 4The glass assembly 100-3 of the illustrated embodiment exemplarily shows a frame structure 160b arranged around the active display layer 140 and a frame structure 160a arranged around the light-blocking layer 150. The frame structures 160a and 160b can pre-position the active display layer 140 and the light-blocking layer 150, filling the thickness difference between the edges of the active display layer 140 and the light-blocking layer 150 and the adhesive layer, ensuring complete sealing after lamination. Alternatively, the frame structure can be selected from the same material as the adhesive layer. If the thickness of the active display layer 140 and / or the light-blocking layer 150 is sufficiently small, the frame structure can be omitted. Furthermore, as described above, the light-blocking layer 150 covers or substantially covers the entire active display layer 140 along the cross-sectional direction of the glass bodies (first glass body 110 and second glass body 120). Figure 4 The illustrated embodiment demonstrates an example where the light-blocking layer substantially covers the active display layer. For example, the edge of the light-blocking layer may extend more than 1 mm beyond the edge of the active display layer 140.

[0078] In some embodiments, as described above, the glass assembly may include multiple light-blocking layers, each of which may include one or more light-blocking regions. In some embodiments, the glass assembly may include a first light-blocking region and a second light-blocking region disposed on one or different light-blocking layers. When the glass assembly includes only one active display layer, the first light-blocking region and the second light-blocking region respectively correspond to at least a portion of the active display layer. Optionally, the first light-blocking region and / or the second light-blocking region together or individually cover, or together or individually substantially cover, the entire active display layer along the cross-sectional direction of the glass body. Herein, "together covering" means that the set of orthographic projections of the first light-blocking region and the second light-blocking region along the cross-sectional direction of the glass body covers the orthographic projection of the active display layer. That is, the set of sizes or areas of the orthographic projections of the first light-blocking region and the second light-blocking region along the cross-sectional direction of the glass body is greater than or equal to the size or area of ​​the orthographic projection of the active display layer, covering both cases where the orthographic projections of the first light-blocking region and the second light-blocking region intersect each other and cases where they do not intersect each other.

[0079] exist Figure 5 In the embodiment shown, Figure 5 The glass assembly 100-4 is comparable to Figure 2 The glass assembly shown is 100-1 or Figure 3For example, the glass assembly 100-2 shown includes multiple light-blocking layers arranged on both sides of an active display layer 140. Specifically, the first light-blocking layer 150 is attached to the active display layer 140 via a third adhesive layer 130c and includes a first light-blocking region 150a, a second light-blocking region 150b, and a third light-blocking region 150c, wherein each light-blocking region of the first light-blocking layer 150 corresponds to at least a portion of the active display layer 140. For example, the first light-blocking region 150a, the second light-blocking region 150b, and the third light-blocking region 150c together cover or substantially cover the entire active display layer 140 along the cross-sectional direction of the glass. The second light-blocking layer 151 is attached to the active display layer 140 via the fourth adhesive layer 130d and includes a first light-blocking region 151a, a second light-blocking region 151b, and a third light-blocking region 151c. Each light-blocking region of the second light-blocking layer 151 corresponds at least partially to the active display layer 140. For example, the first light-blocking region 151a, the second light-blocking region 151b, and the third light-blocking region 151c together cover or substantially cover the entire active display layer 140 along the cross-sectional direction of the glass. The overall structure is sandwiched between the first adhesive layer 130a and the second adhesive layer 130b. By switching between dark and non-dark states in the light-blocking regions of the first light-blocking layer 150 and / or the light-blocking regions of the second light-blocking layer 151, an enhanced contrast image display effect, for example, directed towards the vehicle interior and / or vehicle exterior, can be obtained, while reducing the impact of image content on people inside and outside the vehicle. In particular, the enhanced contrast of the image display, which simultaneously provides contrast to both the interior and exterior of the vehicle, can be achieved by switching between dark and non-dark states in multiple non-overlapping light cutoff regions in the cross-sectional direction of the glass assembly, which will not be elaborated here.

[0080] exist Figures 1 to 5 In this implementation, an active display layer is described as an example. It should be understood that an active display layer here encompasses layer structures with or without physical separation within the same layer. When there is no physical separation, an active display layer can achieve segmented image display according to different needs. For active display layers with physical separation, more diverse layouts can also be obtained to meet different needs.

[0081] According to the concept of this disclosure, in some embodiments, an enhanced contrast image display effect can be achieved simultaneously to the vehicle interior and the vehicle exterior by combining multiple active display layers with one or more light cutoff layers. Figures 6 to 8An exemplary glass assembly including multiple active display layers is shown. In some embodiments, the multiple active display layers may be arranged on both sides of at least one light-blocking layer, and in the cross-sectional direction of the glass assembly, the multiple active display layers are staggered or overlapped with each other. The staggering includes the multiple active display layers being staggered with each other and adjacent to each other, and the overlap may be partial overlap or complete overlap, as shown respectively. Figures 6 to 8 As shown. In some embodiments not illustrated, multiple active display layers may be arranged on the same side of at least one light-blocking layer, and the glass assembly includes, for example, a first active display layer and a second active display layer, which are arranged in different layers in the cross-sectional direction of the glass assembly; optionally, the first active display layer and the second active display layer are arranged in different layers and completely or partially overlap in the cross-sectional direction of the glass assembly.

[0082] and Figures 1 to 4 Similarly, depending on different needs, multiple active display layers can be arranged on the surface of the first glass body 110 away from the second glass body 120, or on the surface of the second glass body 120 away from the first glass body 110, or sandwiched between the first glass body 110 and the second glass body 120. Likewise, "between" encompasses various arrangements where the multiple active display layers are directly adjacent to or not directly adjacent to the first glass body 110 or the second glass body 120. Figure 6In the glass assembly 200 of the illustrated embodiment, a plurality of active display layers are sandwiched between a first glass body 110 and a second glass body 120 and are respectively arranged on both sides of a light-blocking layer 150. Here, an example is taken of a single light-blocking layer 150 including a first light-blocking region 150a and a second light-blocking region 150b, and a plurality of active display layers are exemplified by including a first active display layer 140a and a second active display layer 140b. It should be understood that in some embodiments, the first light-blocking region and the second light-blocking region may be disposed on different light-blocking layers. The first light-cutting region 150a corresponds to at least a portion of the first active display layer 140a, and the second light-cutting region 150b corresponds to at least a portion of the second active display layer 140b. This includes the first light-cutting region 150a corresponding to at least a portion of the first active display layer 140a and at least a portion of the second active display layer 140b, and the second light-cutting region 150b corresponding to at least a portion of both the second active display layer 140b and the first active display layer 140a. Optionally, the first light-cutting region and / or the second light-cutting region together or individually cover, or together or individually substantially cover, the first active display layer and / or the second active display layer along the cross-sectional direction of the glass body; or optionally, the first light-cutting region covers or substantially covers the entire first active display layer along the cross-sectional direction of the glass body, and the second light-cutting region covers or substantially covers the entire second active display layer along the cross-sectional direction of the glass body. It should be understood that, depending on different needs, in embodiments not shown, the glass assembly may also include more active display layers. Similarly, depending on different needs, the light-blocking layer 150 may include more light-blocking regions corresponding to at least a portion of each of the multiple active display layers.

[0083] Figure 6 In the illustrated embodiment, at least one light-blocking layer is sandwiched between the first glass body 110 and the second glass body 120. Specifically, a light-blocking layer 150, including a first light-blocking region 150a and a second light-blocking region 150b, is attached to the second active display layer 140b via a third adhesive layer 130c and to the first active display layer 140a via a fourth adhesive layer 130d. The entire structure is sandwiched between the first adhesive layer 130a and the second adhesive layer 130b. The first light-blocking region 150a corresponds to at least a portion of the first active display layer 140a, that is, along the cross-sectional direction of the glass body, the first light-blocking region 150a can cover part or all of the first active display layer 140a. The second light-blocking region 150b corresponds to at least a portion of the second active display layer 140b, that is, along the cross-sectional direction of the glass body, the second light-blocking region 150b can cover part or all of the second active display layer 140b. Figure 6In the illustrated embodiment, the first light-cutting region 150a covers or substantially covers the entire first active display layer 140a along the cross-sectional direction of the glass body, and the second light-cutting region 150b covers or substantially covers the entire second active display layer 140b along the cross-sectional direction of the glass body. Similarly, "substantially covers" here means that the size or area of ​​the orthographic projection of each light-cutting region along the cross-sectional direction of the glass body (or glass assembly) is approximately equal to the size or area of ​​the orthographic projection of each active display layer; that is, the size or area of ​​the orthographic projection of each light-cutting region is consistent with the size or area of ​​the orthographic projection of each active display layer, or the size or area of ​​the orthographic projection of each light-cutting region is slightly larger or slightly smaller, preferably slightly larger than the size or area of ​​the orthographic projection of each active display layer. For example, the edge of the first light-cutting region 150a may extend beyond the edge of the first active display layer 140a by more than 1 mm, and the edge of the second light-cutting region 150b may extend beyond the edge of the second active display layer 140b by more than 1 mm, preferably exceeding by 1 mm to 5 mm, for example, 3 mm, thereby ensuring the aforementioned effect required by the glass assembly.

[0084] Figure 6 In the illustrated embodiment, the first active display layer 140a and the second active display layer 140b are respectively arranged on both sides of the light-blocking layer 150, and the first active display layer 140a and the second active display layer 140b are staggered from each other in the cross-sectional direction of the glass assembly 200. Preferably, the first active display layer 140a and the second active display layer 140b are staggered from each other and adjacent to each other, which is beneficial to the overall appearance of the glass assembly. In this document, "adjacent" means that the two staggered layers in the cross-sectional direction of the glass assembly are adjacent and close to each other. For example, the distance between them may be less than or equal to 3 mm, less than or equal to 2 mm, less than or equal to 1 mm, etc. Here, it refers to the first active display layer 140a and the second active display layer 140b, which are staggered from each other in the cross-sectional direction of the glass assembly, being adjacent and close to each other.

[0085] By providing multiple active display layers and combining at least one light-blocking layer in a regionalized manner, the glass assembly of this disclosure can selectively obtain an image display effect with enhanced contrast facing different sides of the glass assembly 200. For example, depending on different needs, when the first active display layer 140a displays an image, the first light-blocking region 150a can be switched to a dark state, thereby providing an image display effect with enhanced contrast facing the vehicle interior, providing privacy for the image content, and reducing the impact on people outside the vehicle. At the same time, the second light-blocking region 150b can also be switched to a dark state to provide privacy for the vehicle interior, or the second light-blocking region 150b, which remains in a non-dark state, can, for example, meet the viewing field needs of the driver or passengers. When the second active display layer 140b displays an image, the second light cutoff region 150b can be switched to a dark state, thereby providing an image display effect with enhanced contrast facing the outside of the vehicle and reducing the impact of the image content on the occupants inside the vehicle. At the same time, the first light cutoff region 150a can also be switched to a dark state to provide privacy for the inside of the vehicle. Alternatively, keeping the first light cutoff region 150a in a non-dark state can, for example, meet the viewing needs of the driver or passengers. Of course, in some cases, both the first light cutoff region 150a and the second light cutoff region 150b can be switched to a dark state, and the first active display layer 140a and the second active display layer 140b can display images simultaneously, thereby achieving, for example, an image display effect with enhanced contrast facing both the inside and outside of the vehicle. Alternatively, both the first light-blocking region 150a and the second light-blocking region 150b can be switched to a non-dark state, and the first active display layer 140a and the second active display layer 140b can display images simultaneously. The non-dark state of the first light-blocking region 150a and the second light-blocking region 150b will not have an adverse effect on the display effect of the images on the first active display layer 140a and the second active display layer 140b.

[0086] Similarly, in some embodiments, the glass assembly 200 may also include a frame structure arranged around the first active display layer 140a and / or the second active display layer 140b and / or the light-blocking layer 150. For example, Figure 6 An illustrative example is shown of a frame structure 160d (showing only one side of the first active display layer 140a) arranged around the first active display layer 140a and a frame structure 160c (showing only one side of the second active display layer 140b) arranged around the second active display layer 140b.

[0087] exist Figure 6 In some variations of the glass assembly 200 of the illustrated embodiment, multiple light-blocking layers may also be arranged on both sides of at least one active display layer. For example, multiple light-blocking layers may be arranged on both sides of at least one active display layer. Figure 6In this embodiment, the light-blocking layer 150 is replaced with an active display layer, the first active display layer 140a is replaced with a first light-blocking layer, and the second active display layer 140b is replaced with a second light-blocking layer. Thus, the glass assembly may include a first light-blocking layer and a second light-blocking layer disposed on both sides of at least one active display layer, and each light-blocking layer may include one or more light-blocking regions corresponding to at least a portion of the at least one active display layer. When a light-blocking layer is not divided into sections and includes only one light-blocking region, that one light-blocking layer can be considered as a single light-blocking region. In this variant, the first light-blocking layer and the second light-blocking layer are staggered relative to each other in the cross-sectional direction of the glass assembly. Preferably, the first light-blocking layer and the second light-blocking layer are staggered relative to each other and adjacent to each other, and the first light-blocking layer and the second light-blocking layer together cover or substantially cover the entire at least one active display layer along the cross-sectional direction of the glass body. In this way, by providing multiple light-cutting layers, and by switching between dark and non-dark states through one or more light-cutting regions of the first light-cutting layer and / or one or more light-cutting regions of the second light-cutting layer, the glass assembly can achieve an image display effect with enhanced contrast facing different sides. In particular, it can simultaneously provide an image display effect with enhanced contrast facing, for example, facing the interior and exterior of the vehicle, which will not be elaborated here.

[0088] exist Figure 7 In the glass assembly 200-1 of the illustrated embodiment and some variations thereof, the first active display layer 140a and the second active display layer 140b may overlap each other and partially overlap. In other words, in some embodiments according to different needs, the first light-blocking region 150a corresponds to at least a portion of the first active display layer 140a and at least a portion of the second active display layer 140b, and / or the second light-blocking region 150b corresponds to at least a portion of the second active display layer 140b and at least a portion of the first active display layer 140a. For example, the first light-blocking region 150a covers a portion of the first active display layer 140a or covers or substantially covers the entire first active display layer 140a and covers a portion of the second active display layer 140b along the cross-sectional direction of the glass body, and / or the second light-blocking region 150b covers a portion of the second active display layer 140b or covers or substantially covers the entire second active display layer 140b and covers a portion of the first active display layer 140a along the cross-sectional direction of the glass body. Figure 7The example illustrates a first light-blocking region 150a covering a portion of the first active display layer 140a and a portion of the second active display layer 140b along the cross-sectional direction of the glass body, and a second light-blocking region 150b covering a portion of the second active display layer 140b and a portion of the first active display layer 140a along the cross-sectional direction of the glass body. Optionally, the first light-blocking region 150a covers a portion of the first active display layer 140a, or covers or substantially covers the entire first active display layer 140a and a portion of the second active display layer 140b along the cross-sectional direction of the glass body, and the first light-blocking region 150a and the second light-blocking region 150b together cover or substantially cover the entire second active display layer 140b along the cross-sectional direction of the glass body, or the second light-blocking region 150b covers a portion of the second active display layer 140b but does not cover the first active display layer 140a; or Optionally, the second light-cutting region 150b covers a portion of the second active display layer 140b, or covers or substantially covers the entire second active display layer 140b, and also covers a portion of the first active display layer 140a, along the cross-sectional direction of the glass. Alternatively, the first light-cutting region 150a and the second light-cutting region 150b may together cover or substantially cover the entire first active display layer 140a along the cross-sectional direction of the glass, or the first light-cutting region 150a may cover a portion of the first active display layer 140a without covering the second active display layer 140b. Figure 7 The glass assembly 200-1 and some variations thereof, by switching between dark and non-dark states in different light-cutting regions and combining corresponding portions of the first active display layer 140a and / or the second active display layer 140b to display images, can also achieve an enhanced contrast image display effect facing different sides of the glass assembly 200-1. Furthermore, in Figure 7 In the illustrated embodiments and some variations thereof, a light-cutting region can simultaneously cover portions of multiple active display layers, achieving certain additional display effects while ensuring the aforementioned effects required by the glass assembly. For example, when the first light-cutting region 150a switches to a dark state, in addition to the portion of the first active display layer 140a corresponding to the first light-cutting region 150a providing an image display effect with enhanced contrast to the vehicle interior, the corresponding portion of the second active display layer 140b simultaneously covered by the first light-cutting region 150a in the cross-sectional direction of the glass assembly can also achieve an image display effect with enhanced contrast, thus diversifying the application methods.

[0089] Similarly, in Figure 7 In some variations of the glass assembly 200-1 of the illustrated embodiment, multiple light-blocking layers may also be arranged on both sides of at least one active display layer. For example, multiple light-blocking layers may be arranged on both sides of at least one active display layer. Figure 7In this variation, the light-blocking layer 150 is replaced with an active display layer, the first active display layer 140a is replaced with the first light-blocking layer, and the second active display layer 140b is replaced with the second light-blocking layer. In this variant, the first and second light-blocking layers overlap and partially overlap each other in the cross-sectional direction of the glass assembly. Depending on the needs, the first and / or second light-blocking layers may jointly or individually cover, or jointly or individually substantially cover, the entirety of at least one active display layer along the cross-sectional direction of the glass; and / or the first light-blocking layer may cover a portion of at least one active display layer or cover or substantially cover the entirety of at least one active display layer along the cross-sectional direction of the glass, and / or the second light-blocking layer may cover a portion of at least one active display layer or cover or substantially cover the entirety of at least one active display layer along the cross-sectional direction of the glass. By switching between dark and non-dark states in one or more light-blocking regions of different light-blocking layers, an enhanced contrast image display effect facing different sides of the glass assembly can also be obtained.

[0090] Figure 8 An exemplary embodiment of the glass assembly 200-2 is shown, with Figure 7 The difference in the illustrated embodiment is that, in the cross-sectional direction of the glass assembly 200-2, the first active display layer 140a and the second active display layer 140b completely overlap. The first light-blocking region 150a and the second light-blocking region 150b together cover or substantially cover the entire first active display layer 140a along the cross-sectional direction of the glass body, and the first light-blocking region 150a and the second light-blocking region 150b together cover or substantially cover the entire second active display layer 140b along the cross-sectional direction of the glass body. For Figure 8In the illustrated embodiment, the first light-blocking region 150a and the second light-blocking region 150b together substantially cover the entire first active display layer 140a along the cross-sectional direction of the glass body, and the first light-blocking region 150a and the second light-blocking region 150b together substantially cover the entire second active display layer 140b along the cross-sectional direction of the glass body. In this case, the first light-blocking region 150a can be switched to a dark state, thereby enabling the portion of the first active display layer 140a corresponding to the first light-blocking region 150a to provide, for example, an image display effect with enhanced contrast facing the vehicle interior, a privacy effect for the image content, and reduced impact on people outside the vehicle. Optionally, while the first light-blocking region 150a switches to a dark state, the second light-blocking region 150b can remain in a non-dark state to meet the observation needs of the driver or passengers, or to ensure that the display image effect of the portion of the first active display layer 140a corresponding to the second light-blocking region 150b is not adversely affected. Alternatively, the second light-blocking region 150b can also switch to a dark state to provide privacy for the vehicle interior, or to allow the portion of the first active display layer 140a corresponding to the second light-blocking region 150b to simultaneously provide an enhanced contrast image display effect facing the vehicle interior, provide privacy for the image content, and reduce the impact on people outside the vehicle. A similar effect can also be achieved by switching between a dark state and a non-dark state in the first light-blocking region 150a and / or the second light-blocking region 150b for the second active display layer 140b, which will not be elaborated upon here. In some cases, for both the first active display layer 140a and the second active display layer 140b, by switching both the first light cutoff area 150a and the second light cutoff area 150b to a dark state, an image display effect with enhanced contrast facing both the vehicle interior and exterior can be obtained, and the impact of the image content on people inside and outside the vehicle can be reduced.

[0091] It should be understood that Figure 8 The layers comprising the first active display layer 140a and the second active display layer 140b, and the light-blocking layer 150, are shown to have approximately the same length and / or width as the first glass body 110 and the second glass body 120. In some embodiments, the first active display layer 140a and / or the second active display layer 140b and / or the light-blocking layer 150 may also have a frame structure.

[0092] Similarly, in Figure 8 In some variations of the glass assembly 200-2 of the illustrated embodiment, multiple light-blocking layers may also be arranged on both sides of at least one active display layer. For example, multiple light-blocking layers may be arranged on both sides of at least one active display layer. Figure 8In this variation, the light-blocking layer 150 is replaced with an active display layer, the first active display layer 140a is replaced with the first light-blocking layer, and the second active display layer 140b is replaced with the second light-blocking layer. In this variant, the first and second light-blocking layers overlap completely in the cross-sectional direction of the glass assembly. The first and second light-blocking layers individually or substantially cover the entirety of at least one active display layer along the cross-sectional direction of the glass. That is, the first light-blocking layer covers or substantially covers the entirety of at least one active display layer along the cross-sectional direction of the glass, and the second light-blocking layer covers or substantially covers the entirety of at least one active display layer along the cross-sectional direction of the glass. By switching between dark and non-dark states in one or more light-blocking regions of different light-blocking layers, an image display effect with enhanced contrast facing different sides of the glass assembly can also be obtained.

[0093] It should be understood that Figures 6 to 8In an exemplary embodiment, similarly, the interval between the adjacent first light-blocking regions 150a and 150b corresponding to the first active display layer 140a and the second active display layer 140b can be less than or equal to 0.5 mm, less than or equal to 0.4 mm, less than or equal to 0.3 mm, less than or equal to 0.2 mm, or less than or equal to 0.1 mm. When the interval is, for example, less than or equal to 0.1 mm, the gap can be made invisible to the naked eye, thus ensuring aesthetics. It should be understood that, depending on different needs, the first active display layer and the second active display layer can be staggered and arranged in different areas of the glass assembly, and preferably the first active display layer and the second active display layer are arranged on both sides of at least one light-blocking layer. Accordingly, the interval between the first light-blocking region and the second light-blocking region is not limited. Preferably, for the case where a plurality of first light-cut-off regions correspond to at least a portion of a first active display layer or at least a portion of each of the first active display layers and / or a plurality of second light-cut-off regions correspond to at least a portion of a second active display layer or at least a portion of each of the second active display layers, the interval between the plurality of first light-cut-off regions may be less than or equal to 0.5 mm, less than or equal to 0.4 mm, less than or equal to 0.3 mm, less than or equal to 0.2 mm, or less than or equal to 0.1 mm, and / or the interval between the plurality of second light-cut-off regions may be less than or equal to 0.5 mm, less than or equal to 0.4 mm, less than or equal to 0.3 mm, less than or equal to 0.2 mm, or less than or equal to 0.1 mm. The same applies to the case of multiple optical cutoff layers. That is, the spacing between multiple optical cutoff regions adjacent to each other in the multiple optical cutoff layers is also set in the same way. For example, preferably, for one or more optical cutoff regions disposed in different optical cutoff layers, the spacing between multiple optical cutoff regions adjacent to each other corresponding to at least part of an active display layer or at least part of an active display layer that is adjacent to each other in the multiple active display layers is less than or equal to 0.5 mm, less than or equal to 0.4 mm, less than or equal to 0.3 mm, less than or equal to 0.2 mm, or less than or equal to 0.1 mm.

[0094] Figure 9 An exemplary embodiment is shown in which the light-blocking layer 150 substantially covers the entire active display layer 140, and in... Figure 1 The glass assembly 100 shown is an example. It should be understood that, although... Figure 9The first light-cut-off region 150a, the second light-cut-off region 150b, and the third light-cut-off region 150c of the active display layer 140 and the light-cut-off layer 150 are all shown in a generally rectangular shape. Subject to the present disclosure, the active display layer, light-cut-off layer, and light-cut-off region herein encompass any suitable shape, including but not limited to squares, triangles, sectors, other shapes with curved or straight edges, etc. It should be understood that different shapes or sizes of light-cut-off regions and / or different numbers of light-cut-off regions and / or the size of the light-cut-off regions covering the active display layer can be determined according to the shape or size of the area where the image to be displayed is to be displayed and / or the shape or size of the area where the corresponding effect is to be provided.

[0095] When the glass assembly is used as, for example, a windshield, rear windshield, or corner window, it is suitable for cooperating with a weatherstripping when installed in the vehicle and in its fully usable state. When the glass assembly is used as a door window, it is suitable for cooperating with a waterstop strip (also a type of weatherstripping) when installed in the vehicle and in its fully usable state (i.e., when the door window is fully closed), for example... Figures 10 to 12 The water-cutting strip 170 is shown as an example. The water-cutting strip is a rubber sealing strip located at the bottom of the door glass between the door glass and the door frame. It is used to cut off water droplets, water mist and dust on the glass surface when the door glass is raised or lowered. It also has an aesthetic function, such as hiding the connection lines and control lines of the active display layer 140 and the light cutoff layer 150 under the sealing strip so that they are not visible.

[0096] In some embodiments, the glass assembly includes a control unit, which includes a vehicle control unit and / or a remote control unit and / or an electronic control unit for the active display layer and / or an electronic control unit for the light-blocking layer. The control unit may be configured to: acquire an instruction for an area of ​​the active display layer to display an image, or determine an area of ​​the active display layer to display an image; and, in response to displaying an image in an area of ​​the active display layer, to set at least one light-blocking area of ​​the light-blocking layer corresponding to the area of ​​the active display layer to a dark state, or to set the at least one light-blocking area to a non-dark state. It should be understood that the control unit here may include independent control units located in different physical locations, or it may include an integrated control unit integrated in the same physical location.

[0097] In some embodiments, the glass assembly may include a human-machine interface unit, the control unit including at least an electronic control unit of the human-machine interface unit configured to determine an area on the active display layer where an image is displayed; optionally, the control unit may further include a vehicle control unit and / or a remote control unit and / or an electronic control unit of the active display layer and / or an electronic control unit of the light cutoff layer.

[0098] In a glass assembly that includes a human-machine interface (HMI) unit, the HMI unit can communicate with the glass assembly via an external interface and / or a wireless transceiver to sense information such as, but not limited to, touch information and / or voice information and / or motion information, wherein the motion information includes, but is not limited to, gestures and / or postures and / or movements. Optionally, the HMI unit may include a contact-based interaction unit or a contactless interaction unit. Accordingly, the glass assembly may include a functional layer such as a touch layer (e.g., a capacitive touch film), the function of which is well known in the art and will not be described in detail here. The contactless interaction unit may be configured near the edge of the glass body and disposed on and / or near the surface of the glass body. For contactless interaction, since no touch layer is required, the glass assembly can have relatively higher light transmittance and transparency. Optionally, the contactless interaction unit includes a proximity sensor and / or a distance sensor and / or an image sensor. Preferably, the proximity sensor may be an ultrasonic sensor or an infrared sensor, and the distance sensor may be a laser rangefinder, an ultrasonic rangefinder, or an infrared rangefinder. Preferably, the distance sensor may be a time-of-flight (TOF) sensor. It should be understood that the above-described exemplary contactless interaction units can be used independently, or combined with each other or integrated with related components. For example, depending on different needs, the human-machine interaction unit may be configured as a camera with an image sensor, such as a CCD camera, i.e., a digital camera with a charge-coupled device (CCD) image sensor. Furthermore, the operating principles of the above-described exemplary contactless interaction units are known to those skilled in the art and will not be elaborated upon here.

[0099] It should be understood that, for motion information, gestures refer to the specific movements and postures a person exhibits when using their arms, such as specific hand gestures formed by the position and shape of the palm and fingers. Posture refers to the appearance of the human body. Actions encompass the activities or movements of the human body, including, for example, changes in the position of facial features (i.e., changes in facial expressions), changes in the position of limbs (i.e., changes in movement), or changes in the relative position of the human body to its environment (i.e., changes in relative position). It should be understood that the above-exemplary examples of motion information and the working principles of the information they provide are known to those skilled in the art and will not be elaborated upon here.

[0100] Depending on the specific needs, multiple light cut-off regions of a light cut-off layer, or one or more light cut-off regions of each light cut-off layer and / or corresponding portions of one or more active display layers, can be controlled individually. This enables various adjustment functions such as segmented display, dynamic display, and flowing display to meet different user functional requirements. Figures 10 to 12 Each example shows the following: Figures 1 to 8 The application of any type of glass component to the door glass.

[0101] First see Figure 10 ,by Figure 2 Taking the glass assembly 100-1 shown as an example, the glass assembly 100-1 is typically placed in a roughly vertical direction after being installed in the vehicle. The arrow in the figure indicates the direction towards the front of the vehicle, meaning the first light-blocking area 150a, the second light-blocking area 150b, and the third light-blocking area 150c are arranged sequentially from the front of the vehicle to the rear. In this embodiment, the first light-blocking area 150a is switched to a dark state, and the corresponding portion of the active display layer 140 displays the image 180. The displayed image 180 has enhanced contrast or clarity. Since the active display layer 140 is closer to the second glass body facing the vehicle interior than the light-blocking layer, the effect of displaying images inside the vehicle is improved. In this way, in some situations, the image 180 can be displayed only in the area of ​​the door glass closest to the front of the vehicle, conforming to ergonomic design to meet the needs of the driver and passengers for viewing images, while the remaining areas of the door glass (the second light-blocking area 150b and the third light-blocking area 150c) remain in a non-dark state to meet the needs of the driver and passengers for viewing the outside of the vehicle. Furthermore, since the first light cutoff region 150a corresponding to the portion of the image 180 displayed by the active display layer 140 is in a dark state, it also provides privacy protection for the image content and reduces the impact on people outside the vehicle. It should be understood that for... Figure 1 and Figure 4 ,or Figures 5 to 8 The glass assembly shown in the embodiments, as well as the glass assembly not shown based on the concept of this disclosure, can also achieve similar effects as described above.

[0102] Figure 11 In the embodiment shown, with Figure 3Taking the glass assembly 100-2 shown as an example. In this embodiment, the third light-cutting region 150c is switched to a dark state, and the corresponding portion of the active display layer 140 displays the image 180. The displayed image 180 has enhanced contrast or clarity. Since the active display layer 140 is closer to the first glass body facing the outside of the vehicle than the light-cutting layer, the effect of displaying images outside the vehicle is improved. In this way, in some cases, the image 180 can be displayed only in the area of ​​the door glass near the rear of the vehicle, meeting the needs of people outside the vehicle to observe the image, realizing information interaction between the inside and outside of the vehicle and reducing the impact of the displayed image on people inside the vehicle, while keeping the remaining areas of the door glass (the first light-cutting region 150a and the second light-cutting region 150b) in a non-dark state, meeting the needs of the driver and passengers to observe the outside of the vehicle. It should be understood that for Figures 5 to 8 The glass assembly shown in the embodiments, as well as the glass assembly not shown based on the concept of this disclosure, can also achieve similar effects as described above.

[0103] Figure 12 In the embodiments shown, the following is still used: Figure 2 Taking the glass assembly 100-1 shown as an example. In this embodiment, the first light-cutting region 150a, the second light-cutting region 150b, and the third light-cutting region 150c are all switched to a dark state. That is, approximately the entire active display layer 140 can be used to display the image 180 towards the vehicle interior. Of course, depending on different needs, images can also be displayed only in the portions corresponding to each light-cutting region, while the remaining light-cutting regions remain dark to provide privacy for the vehicle interior. This 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 when an electronic rearview mirror is installed. In some cases, the first light-cutting region 150a, the second light-cutting region 150b, and the third light-cutting region 150c can also be switched to a non-dark state, so as not to adversely affect the image display effect of the active display layer 140. It should be understood that for Figure 1 , Figures 3 to 8 The glass assembly shown in the embodiments, as well as glass assemblies not shown based on the concept of this disclosure, can also achieve similar effects as described above depending on different needs.

[0104] Regardless of the arrangement and combination, the glass assembly of this disclosure advantageously provides, in different zones according to different needs, image display functions that enhance contrast, privacy functions for image content on the image display side, and functions that reduce adverse effects on the non-image display side, bringing users a rich and comfortable user experience. It should be understood that in the possible embodiments described or not described, various improvements can be used independently or in combination, facilitating the application of the glass assembly of this disclosure in various occasions to meet the diverse needs of users.

[0105] This disclosure also provides a display method for controlling a glass assembly to display an image and a computer device for implementing the display method. Figure 13 As shown, the computer device 300 (hereinafter referred to as device 300) for implementing the display method provided in this disclosure may include a memory 310 and a processor 320.

[0108] Specifically, regarding the display method, the display method disclosed herein is used to control the aforementioned glass assembly to display images, in conjunction with... Figure 14 As shown, an exemplary display method may include:

[0109] S1, obtain the instruction for the area of ​​the image displayed on the active display layer, or determine the area of ​​the image displayed on the active display layer;

[0112] In some embodiments, the display method further includes: when the display of the image stops in the area where the image is displayed, switching the at least one light-cut-off region to a non-dark state, or keeping the at least one light-cut-off region in a non-dark state; optionally, when the light-cut-off region is in a non-dark state, the visible light transmittance of the light-cut-off region is 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 is the highest transmittance of the light-cut-off region.

[0113] In some embodiments, the display method obtains an instruction from a control unit to display an image area on the active display layer, or determines an image area on the active display layer; displays the image in the area of ​​the image; and, in response to the image being displayed in the area of ​​the image, sets at least one light-blocking region of the light-blocking layer of the glass assembly to a dark state, or sets the at least one light-blocking region to a non-dark state.
