[0002] With the rapid development of automobile industry, as a good medium for transferring information to the interior of a vehicle and / or the exterior of the vehicle, vehicle window glass has been widely valued by vehicle manufacturers and favored by consumers. Compared with using other in-vehicle positions (for example, a display on a rear side of a vehicle seat) for display, the vehicle window glass has higher convenience, larger usable area, more durability and better user experience. For example, a projection film can be applied on a rear windshield of a taxi for displaying advertisement content such as picture or video to the outside of the vehicle.
[0003] Although the projection to the outside of the vehicle through the vehicle window glass can meet the requirements of some consumers, the vehicle manufacturers and the consumers expect to provide more diversified experience by using the vehicle window glass.SUMMARY

[0053] The implementation and use of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed merely exemplify the specific ways of implementing and using the present disclosure, and do not limit the scope of the disclosure. When describing the structural positions of various components, such as the directions of upper, lower, top, bottom, etc., the description is not absolute, but relative. When the various components are arranged as shown in the figures, these directional expressions are appropriate, but when the positions of the various components in the figures would be changed, these directional expressions would also be changed accordingly.
[0054] In this context, the expression "comprising" or similar expressions "having" and so on which are synonymous are open, and do not exclude additional unlisted elements, steps or ingredients.
[0055] In this context, the terms "first" , "second" and so on are not used to limit the sequence and the number of components unless otherwise stated.
[0056] In this context, unless otherwise specifically defined, terms such as "attach" should be understood broadly. For example, it can be fixed connection, detachable connection or integrated; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meanings of the above terms in this context can be understood according to specific situations.
[0057] In this context, the meaning of "a plurality of" refers to two or more than two, unless otherwise specified.
[0058] In this context, "surface" of the glass body or each laminated layer structure is a surface with a larger surface area in all surfaces of the glass body or each laminated layer structure, and "edge" is a surface defined by a thickness in all surfaces of the glass body or each laminated layer structure. "Section" of the glass assembly is taken along the thickness direction of the glass assembly, and "cross-section direction" is a direction perpendicular to the surface of the glass body or a normal direction of the surface of the glass body.
[0059] In this context, a glass assembly applied to a vehicle window glass will be described, but it does not exclude that the glass assembly can be applied to other environments such as door, window, curtain wall, airplane glass or ship glass. When the glass assembly is described as the vehicle window glass of a vehicle, "outside" and "inside" refer to the directions relative to 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 a direction substantially perpendicular to the ground. It should be understood that the vehicle window glass according to the embodiment of the present disclosure includes, but is not limited to, front windshield, rear windshield, vehicle door glass (including front vehicle door glass and rear vehicle door glass) or corner window glass, which can provide different image display effects based on different requirements.
[0060] In various described embodiments, 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 suitable for the conventional range, and is not limited as shown in the figures. In addition, although it is shown as plane glass in the figures, the glass assembly of the present disclosure may also be curved glass. In various embodiments, it is described as an independent glass body; however, in some undescribed cases, special coating can also be used on the surface of the glass body to improve other properties such as thermal insulation and / or comfort.
[0061] For manufacturers and most vehicle users, it is desirable to use the vehicle window glass to achieve various forms of image display effects, for example, displaying an image toward the inside of the vehicle and providing privacy effect of image content and reducing the influence on people outside the vehicle, and optionally displaying the image to the outside of the vehicle, or displaying the image to the outside of the vehicle while displaying the image to the inside of the vehicle, for example, displaying welcome information or warning information, etc. to people or vehicle outside the vehicle to achieve information interaction between the inside and outside of the vehicle, which puts forward more diversified design requirements for the vehicle window glass. It has been recognized that in the case where the projection to the inside of the vehicle is realized through the vehicle window glass, the driver and the passenger tend to be interested in the image displayed in some regions, for example, the driver and the passenger prefer a display region with a smaller head rotation angle, that is, for example, a region on the vehicle door glass relatively closer to the front of the vehicle. In the case of the projection to the outside of the vehicle, it is also desirable that the displayed image does not adversely affect the driver, for example, the region on the vehicle door glass where the image is displayed to the outside of the vehicle is relatively closer to the rear of the vehicle.
[0062] In this context, "privacy" is for people inside the vehicle, that is, in the case that the image is displayed inside the vehicle, the vehicle window glass can make people outside the vehicle unable to clearly see the displayed image content, thereby realizing the privacy protection function. In this context, there is no limitation on the displayed image, for example, it can be static text, numbers, symbols or pictures, or it can also be dynamic video.
[0063] According to the concept of the present disclosure, a glass assembly is provided. The glass assembly comprises: a glass body; an active display layer arranged on a surface of the glass body for displaying an image and 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 be switchable between a non-dark state and a dark state, and the light-cutoff layer comprising one or more light-cutoff layers, wherein each light-cutoff region corresponds to at least portion of the active display layer.
[0064] With the above solution of the present disclosure, depending on different requirements, the image display function provided by the active display layer in the glass assembly of the present disclosure can encompass displaying the image toward the outside of the vehicle and / or toward the inside of the vehicle. Further, the glass assembly of the present disclosure is provided with the light-cutoff layer including the plurality of light-cutoff regions, and depending on different requirements, one or more light-cutoff layers may be arranged on any side or both sides of at least one active display layer, or one or more active display layers may be arranged on any side or both sides of at least one light-cutoff layer. It should be understood that, in the following description, unless otherwise specified, the light-cutoff layer includes one or more light-cutoff layers, and the active display layer includes one or more active display layers. In this context, "active display" means that it can emit light by itself to display the image when powered without a light source. "light-cutoff" means that when the light-cutoff region is in the dark state, light can be cutoff to prevent the light from being transmitted through the light-cutoff layer, and the light-cutoff layer may also be referred to as a light valve. Herein, "dark state" means that when the light-cutoff region is switched to this state, a visible light transmittance of the light-cutoff 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 light transmittance (for example, 0.5%) of the light-cutoff region. "Non-dark state" means that when the light-cutoff region is switched to this state, the visible light transmittance is greater than that in the dark state. For example, when the light-cutoff region is in the non-dark state, the visible light transmittance of the light-cutoff region 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 the highest light transmittance of the light-cutoff region. Optionally, when the light-cutoff region is in the dark state, in the cross-sectional direction of the glass assembly, the visible light transmittance of the glass assembly 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%, less than or equal to 1%; when the light-cutoff region is in the non-dark state, in the cross-sectional direction of the glass assembly, the visible light transmittance of the glass assembly 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%. The visible light transmittance of the light-cutoff region in the non-dark state is greater than the visible light transmittance of the light-cutoff region in the 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%, greater than or equal to 80%. Herein, the visible light transmittance is the light transmission in the visible spectrum region, expressed with %, and it is measured according to the standard ISO 9050: 2003 (light source D65; 2° observer) .
[0065] According to the present disclosure, the non-dark state of the light-cutoff region may encompass one or more stable states corresponding to different visible light transmittances, such as two, three, four, five or more, so that different light transmittances may be freely stepless adjusted within the defined range of different highest light transmittances of the light-cutoff regions of selected different forms of light-cutoff layer depending on different requirements. The light-cutoff region in the dark state can cut off the light for displaying the image from the active display layer, thereby improving the contrast of the image on the opposite side and enhancing the definition of the image displayed on the active display layer. When applied to, for example, the vehicle door glass and displaying the image to the inside of the vehicle, the glass assembly of the present disclosure not only enables people inside the vehicle to observe a displayed image with enhanced effect, but also enables the function of privacy protection for the content of the displayed image and reduces interference to people outside the vehicle. For example, in a bright light condition (e.g., daytime) , for a region where an image needs to be displayed, the corresponding light-cutoff region located on a side of the active display layer that faces the outside of the vehicle may be switched to the dark state to avoid interference from ambient light outside the vehicle, thereby providing an image with higher contrast; in a dim light condition (e.g., night or rainy day) , the light-cutoff region switched to the dark state provides the image with high contrast, and meanwhile can also provide privacy protection for the content of the displayed image and reduce interference to people outside the vehicle. When applied to, for example, the vehicle door glass and displaying the image to the outside of the vehicle, the glass assembly of the present disclosure not only enables people outside the vehicle to observe a displayed image with enhanced effect, but also reduces or avoids interference to people inside the vehicle. When the light-cutoff region is switched to the non-dark state, the visible light transmittance of the light-cutoff region may 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 light transmittance of the light-cutoff region, thereby meeting different perspective requirements of people inside the vehicle to the outside of the vehicle, or not affecting the requirements of people inside the vehicle and / or people outside the vehicle for observing the image displayed by the active display layer.
[0066] Advantageously, the active display layer is a transparent active display layer, that is, the active display layer has a higher visible light transmittance to facilitate the application of the glass assembly, but the application of the active display layer that presents relatively non-transparent due to a relatively low visible light transmittance is not excluded. Preferably, the active display layer includes micro light-emitting diode (Micro-LED or μLED) display layer or organic light-emitting diode (OLED) display layer. OLED is a device that generates electroluminescence by using a multilayer organic thin film structure, and has the characteristics of light weight, high brightness, low power consumption, fast response, high definition, good flexibility, and high luminous efficiency, etc. . Micro-LED is a display technology that integrates micron-scale semiconductor light-emitting diodes (LEDs) in a matrix form on a chip in a high-density manner, and has advantages such as high brightness, high resolution, low power consumption and high reliability, etc. . Due to the self-lighting characteristics of OLED or Micro-LED, it is possible to achieve display effects such as transparent display and flexible display while being suitable for various applications of the glass assembly in a lighter and thinner form.
[0067] When applied to the vehicle window glass, advantageously, the selected active display layer itself has a haze less than 10%, preferably less than 5%, and for different vehicle window glasses, the visible light transmittance may be greater than or equal to 50% (e.g., rear vehicle door glass) . Herein, haze is the ratio of the scattered luminous flux that passes through the sample and deviates from the incident light of normal direction to the transmitted luminous flux, expressed with %. Typically, only the scattered luminous flux deviating from the incident light direction by 2.5 degrees or more is used to calculate the haze, and it is measured by a haze meter according to the standards GB2410 and ASTM D1003.
[0068] Advantageously, the light-cutoff region of the light-cutoff layer has a higher contrast between its highest light transmittance and its lowest light transmittance, here, "contrast" refers to a ratio between the highest light transmittance and the lowest light transmittance. Alternatively, the light-cutoff layer may be a film layer with a contrast greater than or equal to 10: 1, but it should be understood that the contrast of the light-cutoff layer is not necessarily greater than or equal to 10: 1, for example, the light-cutoff layer may be configured as any one of suspended particle (SPD) film layer, electrochromic (EC) film layer, dye-doped polymer dispersed liquid crystal (DDPDLC) film layer, guest-host liquid crystal (GHLC) film layer and electrophoretic film layer. In specific embodiments, the plurality of light-cutoff regions of the light-cutoff layer may be configured as the same or different film layers, for example, including any combination of the film layers listed above.
[0069] According to the present disclosure, each of the plurality of light-cutoff regions of the light-cutoff layer is configured to be switchable between the non-dark state and the dark state, because a user has a need to provide a display of an image in a specific region or a local region of the glass assembly. For example, when the glass assembly is applied to the vehicle door glass, through ergonomic research, a driver or a passenger has more frequent image display requirements in a region of the vehicle door glass (for example, a region on the vehicle door glass that is relatively closer to the front of the vehicle) that is ergonomic (for example, a head rotation angle is small) or tends to display more important information in this region. By providing the sectionalized light-cutoff layer, the light-cutoff region switched to the dark state can provide the image display effect with enhanced contrast and / or the privacy effect of the image content, and the light-cutoff region in the non-dark state can meet the perspective requirement of the driver or the passenger to the outside of the vehicle, thereby ensuring a good observation field of view of the driver and the passenger to the outside of the vehicle, and improving driving safety and driving experience. In addition, it is also possible to provide functional requirements to adapt to more occasions and various weather conditions through this sectionalized design in combination with free stepless adjustment of the light transmittance.
[0070] It should be understood that the glass assembly of the present disclosure encompasses single-layer glass body and laminated glass having multiple layers of glass body. FIG. 1 exemplarily illustrates a glass assembly 100 in the form of laminated glass according to an embodiment, including 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 arranged 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 arranged 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. In the embodiment shown in FIG. 1, taking one active display layer 140 as an example, the active 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. Since the active display layer is adopted and the transparent active display layer is preferred, depending on different requirements, at least one light-cutoff layer may be arranged on any side of the active display layer 140, for example, at least one light-cutoff layer may be arranged on the surface of the first glass body away from the second glass body, or arranged 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, in the embodiment shown in FIG. 1, taking one light-cutoff layer 150 as an example, the light-cutoff layer 150 is sandwiched between the first glass body 110 and the second glass body 120, and specifically, the light-cutoff layer 150 is sandwiched between the first adhesive layer 130a and the second adhesive layer 130b. It should be understood that, based on different requirements, the light-cutoff layers may also be arranged on both sides of the active display layer, which will be further described below in conjunction with specific embodiments.
[0071] In the embodiment shown in FIG. 1, the light-cutoff layer 150 covers or substantially covers the entire active display layer 140 along a cross-sectional direction of the glass body (the first glass body 110 and the second glass body 120) . Here, "cover" means that the orthographic projection of the light-cutoff layer covers the orthographic projection of the active display layer along the cross-sectional direction of the glass body, and "substantially cover" means that the size or area of the orthographic projection of the light-cutoff layer is approximately equal to the size or area of the orthographic projection of the active display layer along the cross-sectional direction of the glass body (or the glass assembly) , that is, the size or area of the orthographic projection of the light-cutoff 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-cutoff layer is slightly greater than or slightly less than, preferably slightly greater than, the size or area of the orthographic projection of the active display layer. For example, the edge of the light-cutoff layer 150 may exceed the edge of the active display layer 140 by 1 mm or more, preferably by 1 mm to 5 mm, such as 3 mm, so as to ensure the above effect required to be obtained by the glass assembly. In addition, when the active display layer 140 and / or the light-cutoff layer 150 covers a local part of the first glass body 110 and the second glass body 120, for example, one of the first adhesive layer 130a and the second adhesive layer 130b attached to the light-cutoff layer 150 in FIG. 1 may be omitted, and the light-cutoff layer 150 is surrounded by the other of the first adhesive layer 130a and the second adhesive layer 130b. Here, "surround" means that the edge of the light-cutoff layer is encapsulated by the adhesive layer on one side of the light-cutoff layer, so that the light-cutoff layer is entirely sandwiched between the first glass body 110 and the second glass body 120.
[0072] According to the present disclosure, the light-cutoff layer may include a plurality of light-cutoff regions corresponding to at least portion of one active display layer, or the light-cutoff layer may include one or more light-cutoff regions corresponding to at least portion of each active display layer of the plurality of active display layers. FIG. 1 exemplarily illustrates three light-cutoff regions corresponding to at least portion of the active display layer 140, that is, a first light-cutoff region 150a, a second light-cutoff region 150b and a third light-cutoff region 150c. It should be understood that the number of light-cutoff regions may also be selected to be two or more than three, for example, four, five, six, etc. according to different requirements. In addition, although one light-cutoff layer is divided into a plurality of light-cutoff regions, an interval between the plurality of light-cutoff regions in one light-cutoff layer 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 when the interval is, for example, less than or equal to 0.1 mm, the gap can be invisible to naked eyes to ensure aesthetics.
[0073] In different embodiments, the active display layer 140 may also be arranged 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, the active display layer 140 in the embodiment shown in FIG. 1 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-cutoff layer 150. Depending on different arrangement positions of the active display layer 140 and the light-cutoff layer 150, an effect of image display toward different sides of the glass assembly 100 can be obtained by the active display layer 140. For example, when the glass assembly 100 is applied to the vehicle window glass, the first glass body 110 may face the outside of the vehicle (which may be referred to as outer glass) , and the second glass body 120 may face the inside of the vehicle (which may be referred to as inner glass) . In this way, according to different requirements, one or more light-cutoff regions of the plurality of light-cutoff regions of the light-cutoff layer 150 can be switched to the dark state or the non-dark state, so that the corresponding portions of the active display layer 140 at different arrangement positions can display images toward the inside of the vehicle and / or the outside of the vehicle. For example, in FIG. 1, when one or more light-cutoff regions are switched to the dark state, the corresponding portion of the active display layer 140 can provide the image display effect with enhanced contrast to the inside of the vehicle while providing the privacy effect of the image content inside the vehicle, and reducing the influence on people outside the vehicle; or, when one or more light-cutoff regions are switched to the non-dark state, the image display effect provided by the corresponding portion of the active display layer 140 will not be adversely affected by the light-cutoff region in the non-dark state. In various application modes, the light-cutoff region keeping the non-dark state can, for example, meet the requirements of the observation field of view of the driver or the passenger.
[0074] As an example, the first adhesive layer 130a, the second adhesive layer 130b and the third adhesive layer 130c are adhesive layers suitable for the laminated glass such as polyvinyl butyral (PVB) , ethylene-vinyl acetate (EVA) and optically clear adhesive (OCA) , etc.
[0075] In a glass assembly 100-1 of another embodiment exemplarily shown in FIG. 2, the adhesive layer includes the first adhesive layer 130a attached to the first glass body 110 and the second adhesive layer 130b attached to the second glass body 120. The difference from the embodiment shown in FIG. 1 is that at least one light-cutoff layer and at least one active display layer are both sandwiched between the first adhesive layer 130a and the second adhesive layer 130b. Specifically, one light-cutoff layer including the first light-cutoff region 150a, the second light-cutoff region 150b and the third light-cutoff region 150c is sandwiched between the first adhesive layer 130a and the third adhesive layer 130c, and one 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-cutoff layer, for example, closer to the inner glass when applied to the vehicle window glass. Similarly, when the active display layer 140 and / or the light-cutoff layer 150 covers a local part of the first glass body 110 and the second glass body 120, one of the two adhesive layers adjacent thereto may be omitted, and the active display layer 140 and / or the light-cutoff layer 150 is surrounded by the other of the two adhesive layers.
[0076] In a glass assembly 100-2 of another embodiment exemplarily shown in FIG. 3, one light-cutoff layer including the first light-cutoff region 150a, the second light-cutoff region 150b and the third light-cutoff region 150c and one active display layer 140 are both sandwiched between the first adhesive layer 130a and the second adhesive layer 130b, and are separated by the third adhesive layer 130c. The difference from the embodiment shown in FIG. 2 is that the active display layer 140 is closer to the first glass body 110 than the light-cutoff layer 150, for example, closer to the outer glass when applied to the vehicle window glass. Similarly, when the active display layer 140 and / or the light-cutoff layer 150 covers a local part 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-cutoff layer 150 may be omitted, and the active display layer 140 and / or the light-cutoff layer 150 is surrounded by the other of the two adhesive layers, which will not be repeated here.
[0077] In some embodiments, the glass assembly may further include a picture frame structure arranged around at least one active display layer and / or at least one light-cutoff layer. For example, the difference from the embodiment shown in FIG. 2 is that, a glass assembly 100-3 of an embodiment shown in FIG. 4 exemplarily illustrates a picture frame structure 160b arranged around the active display layer 140 and a picture frame structure 160a arranged around the light-cutoff layer 150. The picture frame structures 160a and 160b can achieve pre-positioning of the active display layer 140 and the light-cutoff layer 150 to fill the thickness difference between the edges of the active display layer 140 and the light-cutoff layer 150 and the adhesive layers, thereby ensuring complete sealing after lamination. Alternatively, the picture frame structure may be selected to be the same material as the adhesive layer. When the thickness of the active display layer 140 and / or the light-cutoff layer 150 is sufficiently small, the picture frame structure may also be omitted. In addition, as described above, the light-cutoff layer 150 covers or substantially covers the entire active display layer 140 along the cross-sectional direction of the glass body (the first glass body 110 and the second glass body 120) , and the embodiment shown in FIG. 4 exemplarily illustrates the case where the light-cutoff layer substantially covers the active display layer. The edge of the light-cutoff layer may exceed the edge of the active display layer 140 by 1 mm or more, for example.
[0078] In some embodiments, as described above, the glass assembly may include a plurality of light-cutoff layers, each light-cutoff layer may include one or more light-cutoff regions. In some embodiments, the glass assembly may include a first light-cutoff region and a second light-cutoff region arranged in one light-cutoff layer or different light-cutoff layers. When the glass assembly includes only one active display layer, the first light-cutoff region and the second light-cutoff region respectively correspond to at least portion of the one active display layer, optionally, the first light-cutoff region and / or the second light-cutoff region jointly or individually cover or jointly or individually substantially cover the entire one active display layer along the cross-sectional direction of the glass body. Herein, "jointly cover" means that a set of orthographic projections of the first light-cutoff region and the second light-cutoff region covers the orthographic projection of the active display layer along the cross-sectional direction of the glass body, that is, a set of sizes or areas of the orthographic projections of the first light-cutoff region and the second light-cutoff region is greater than or equal to the size or area of the orthographic projection of the active display layer along the cross-sectional direction of the glass body, which encompasses the case where the orthographic projections of the first light-cutoff region and the second light-cutoff region intersect with each other and do not intersect with each other.
[0079] In an embodiment shown in FIG. 5, compared with the glass assembly 100-1 shown in FIG. 2 or the glass assembly 100-2 shown in FIG. 3, a glass assembly 100-4 in FIG. 5 may include, for example, a plurality of light-cutoff layers arranged on two sides of one active display layer 140. Specifically, the first light-cutoff layer 150 is attached to the active display layer 140 through the third adhesive layer 130c, and includes the first light-cutoff region 150a, the second light-cutoff region 150b and the third light-cutoff region 150c, wherein each light-cutoff region of the first light-cutoff layer 150 corresponds to at least portion of the active display layer 140, for example, the first light-cutoff region 150a, the second light-cutoff region 150b and the third light-cutoff region 150c jointly cover or jointly substantially cover the entire one active display layer 140 along the cross-sectional direction of the glass body. A second light-cutoff layer 151 is attached to the active display layer 140 through a fourth adhesive layer 130d, and includes a first light-cutoff region 151a, a second light-cutoff region 151b and a third light-cutoff region 151c, wherein each light-cutoff region of the second light-cutoff layer 151 corresponds to at least portion of the active display layer 140, for example, the first light-cutoff region 151a, the second light-cutoff region 151b and the third light-cutoff region 151c jointly cover or jointly substantially cover the entire one active display layer 140 along the cross-sectional direction of the glass body. The above overall structure is sandwiched between the first adhesive layer 130a and the second adhesive layer 130b. By switching between the dark state and the non-dark state of each light-cutoff region of the first light-cutoff layer 150 and / or each light-cutoff region of the second light-cutoff layer 151, for example, the image display effect with enhanced contrast toward the inside of the vehicle and / or the outside of the vehicle can be obtained, and the influence of the image content on people inside and outside the vehicle can be reduced. In particular, for the image display effect with enhanced contrast toward the inside of the vehicle and the outside of the vehicle at the same time, it can be realized by switching the plurality of light-cutoff regions that do not overlap with each other in the cross-sectional direction of the glass assembly between the dark state and the non-dark state, which will not be repeated here.
[0080] In the embodiments of FIG. 1 to FIG. 5, one active display layer is taken as an example for description, and it should be understood that one active display layer herein encompasses a layer structure with or without physical separation in the same layer. When there is no physical separation, one active display layer can realize the image display in different regions according to different requirements. For the active display layer with physical separation, for example, more diversified layouts can be further obtained to meet different requirements.
[0081] According to the concept of the present disclosure, in some embodiments, the image display effect with enhanced contrast can also be provided toward the inside of the vehicle and the outside of the vehicle simultaneously by combining a plurality of active display layers and one or more light-cutoff layers. FIGS. 6 to 8 exemplarily illustrate glass assemblies including a plurality of active display layers. In some embodiments, the plurality of active display layers may be respectively arranged on two sides of at least one light-cutoff layer, and in the cross-sectional direction of the glass assembly, the plurality of active display layers are staggered from each other or overlapped with each other, the staggered active display layers includes that the plurality of active display layers are staggered from each other and adjacent to each other, and the overlapped active display layers may be partially overlapped or completely overlapped, as shown in FIG. 6 to FIG. 8, respectively. In some embodiments not shown, the plurality of active display layers may be arranged on the same side of at least one light-cutoff layer, and the glass assembly includes, for example, a first active display layer and a second active display layer, and in the cross-sectional direction of the glass assembly, the first active display layer and the second active display layer are arranged in different layers; optionally, in the cross-sectional direction of the glass assembly, the first active display layer and the second active display layer are arranged in different layers and completely overlapped or partially overlapped.
[0082] Similar to the embodiments of FIGS. 1 to 4, depending on different requirements, a plurality of active display layers may be arranged on the surface of the first glass body 110 away from the second glass body 120, or may be arranged on the surface of the second glass body 120 away from the first glass body 110, or may be sandwiched between the first glass body 110 and the second glass body 120. Similarly, "between" encompasses various arrangements in which the plurality of active display layers are directly adjacent to or not directly adjacent to the first glass body 110 or the second glass body 120. In a glass assembly 200 of an embodiment shown in FIG. 6, a plurality of active display layers are sandwiched between the first glass body 110 and the second glass body 120 and are respectively arranged on two sides of one light-cutoff layer 150. Here, taking one light-cutoff layer 150 including the first light-cutoff region 150a and the second light-cutoff region 150b as an example, the plurality of active display layers are illustrated as 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-cutoff region and the second light-cutoff region may be arranged in different light-cutoff layers. The first light-cutoff region 150a corresponds to at least portion of the first active display layer 140a, the second light-cutoff region 150b corresponds to at least portion of the second active display layer 140b, which includes that the first light-cutoff region 150a may correspond to at least portion of the first active display layer 140a and at least portion of the second active display layer 140b, and the second light-cutoff region 150b may correspond to at least portion of the second active display layer 140b and at least portion of the first active display layer 140a. Optionally, the first light-cutoff region and / or the second light-cutoff region jointly or individually covers or jointly or individually substantially covers 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-cutoff region covers or substantially covers the entire first active display layer along the cross-sectional direction of the glass body, and the second light-cutoff 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 requirements, in embodiments not shown, the glass assembly may also include more active display layers, and likewise, depending on different requirements, the light-cutoff layer 150 may include more light-cutoff regions corresponding to at least portion of each active display layer of the plurality of active display layers.
[0083] In the embodiment shown in FIG. 6, at least one light-cutoff layer is sandwiched between the first glass body 110 and the second glass body 120, specifically, one light-cutoff layer 150 including the first light-cutoff region 150a and the second light-cutoff region 150b is attached to the second active display layer 140b through the third adhesive layer 130c, and attached to the first active display layer 140a through the fourth adhesive layer 130d. The above overall structure is sandwiched between the first adhesive layer 130a and the second adhesive layer 130b. The first light-cutoff region 150a corresponds to at least portion of the first active display layer 140a, that is, along the cross-sectional direction of the glass body, the first light-cutoff region 150a can cover portion or all of the first active display layer 140a, and the second light-cutoff region 150b corresponds to at least portion of the second active display layer 140b, that is, along the cross-sectional direction of the glass body, the second light-cutoff region 150b can cover portion or all of the second active display layer 140b. In the embodiment shown in FIG. 6, the first light-cutoff 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-cutoff region 150b covers or substantially covers the entire second active display layer 140b along the cross-sectional direction of the glass body. Similarly, "substantially cover" herein means that the size or area of the orthographic projection of each light-cutoff region is approximately equal to the size or area of the orthographic projection of each active display layer along the cross-sectional direction of the glass body (or the glass assembly) , that is, the size or area of the orthographic projection of each light-cutoff 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-cutoff region is slightly greater than or slightly less than, preferably slightly greater than, the size or area of the orthographic projection of each active display layer. For example, the edge of the first light-cutoff region 150a may exceed the edge of the first active display layer 140a by 1 mm or more, and the edge of the second light-cutoff region 150b may exceed the edge of the second active display layer 140b by 1 mm or more, preferably by 1 mm to 5 mm, such as 3 mm, so as to ensure the above effect required to be obtained by the glass assembly.
[0084] In the embodiment shown in FIG. 6, the first active display layer 140a and the second active display layer 140b are respectively arranged on two sides of the light-cutoff 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 to facilitate the overall appearance of the glass assembly. In this context, "adjacent" means that the two parts staggered from each other in the cross-sectional direction of the glass assembly are adjacent and close to each other, for example, an interval between the two parts 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 means that the first active display layer 140a and the second active display layer 140b staggered from each other in the cross-sectional direction of the glass assembly are adjacent and close to each other.
[0085] By providing a plurality of active display layers in combination with at least one sectionalized light-cutoff layer, the glass assembly of the present disclosure can selectively obtain image display effects with enhanced contrast toward different sides of the glass assembly 200. For example, according to different requirements, when the first active display layer 140a displays an image, the first light-cutoff region 150a may be switched to the dark state, so as to provide the image display effect with enhanced contrast toward the inside of the vehicle, provide the privacy effect of image content, and reduce the influence on people outside the vehicle; meanwhile, the second light-cutoff region 150b may also be switched to the dark state to provide the privacy effect inside the vehicle, or the second light-cutoff region 150b keeping the non-dark state may, for example, meet the requirements of the observation field of view of the driver or the passenger. When the second active display layer 140b displays an image, the second light-cutoff region 150b may be switched to the dark state, so as to provide the image display effect with enhanced contrast toward the outside of the vehicle and reduce the influence of the image content on people inside the vehicle; meanwhile, the first light-cutoff region 150a may also be switched to the dark state to provide the privacy effect inside the vehicle, or the first light-cutoff region 150a keeping the non-dark state may, for example, meet the requirements of the observation field of view of the driver or the passenger. Certainly, in some cases, both the first light-cutoff region 150a and the second light-cutoff region 150b may also be switched to the dark state, and the first active display layer 140a and the second active display layer 140b simultaneously display images, thereby achieving, for example, the image display effect with enhanced contrast toward the inside of the vehicle and the outside of the vehicle simultaneously. Alternatively, both the first light-cutoff region 150a and the second light-cutoff region 150b may also be switched to the non-dark state, and the first active display layer 140a and the second active display layer 140b simultaneously display images, the first light-cutoff region 150a and the second light-cutoff region 150b in the non-dark state will not adversely affect the image display effect of the first active display layer 140a and the second active display layer 140b.
[0086] Similarly, in some embodiments, the glass assembly 200 may further include a picture frame structure arranged around the first active display layer 140a and / or the second active display layer 140b and / or the light-cutoff layer 150. For example, FIG. 6 exemplarily illustrates a picture frame structure 160d (only shown on one side of the first active display layer 140a) arranged around the first active display layer 140a and a picture frame structure 160c (only shown on one side of the second active display layer 140b) arranged around the second active display layer 140b.
[0087] In some variations of the glass assembly 200 of the embodiment shown in FIG. 6, a plurality of light-cutoff layers may also be arranged on two sides of at least one active display layer. For example, the light-cutoff layer 150 in FIG. 6 may be replaced with an active display layer, the first active display layer 140a may be replaced with a first light-cutoff layer, and the second active display layer 140b may be replaced with a second light-cutoff layer. As such, the glass assembly may include the first light-cutoff layer and the second light-cutoff layer arranged on two sides of the at least one active display layer, and each light-cutoff layer may include one or more light-cutoff regions corresponding to at least portion of the at least one active display layer. When one light-cutoff layer is not sectionalized and includes only one light-cutoff region, it may be considered that the one light-cutoff layer is one light-cutoff region. In this variation, in the cross-sectional direction of the glass assembly, the first light-cutoff layer and the second light-cutoff layer are staggered from each other, preferably, the first light-cutoff layer and the second light-cutoff layer are staggered from each other and adjacent to each other, and the first light-cutoff layer and the second light-cutoff layer jointly cover or jointly substantially cover the entire at least one active display layer in the cross-sectional direction of the glass body. In this way, by providing the plurality of light-cutoff layers, and by switching one or more light-cutoff regions of the first light-cutoff layer and / or one or more light-cutoff regions of the second light-cutoff layer between the dark state and the non-dark state, the glass assembly can obtain the image display effect with enhanced contrast toward different sides, and in particular, can simultaneously provide for example the image display effect with enhanced contrast toward the inside of the vehicle and the outside of the vehicle, which will not be repeated here.
[0088] In a glass assembly 200-1 of an embodiment shown in FIG. 7 and some variations thereof, the first active display layer 140a and the second active display layer 140b may be overlapped with each other and partially overlapped with each other. In other words, in some embodiments according to different requirements, the first light-cutoff region 150a corresponds to at least portion of the first active display layer 140a and at least portion of the second active display layer 140b, and / or the second light-cutoff region 150b corresponds to at least portion of the second active display layer 140b and at least portion of the first active display layer 140a. For example, the first light-cutoff region 150a covers portion of the first active display layer 140a or covers or substantially covers the entire first active display layer 140a and covers portion of the second active display layer 140b along the cross-sectional direction of the glass body, and / or the second light-cutoff region 150b covers portion of the second active display layer 140b or covers or substantially covers the entire second active display layer 140b and covers portion of the first active display layer 140a along the cross-sectional direction of the glass body. FIG. 7 exemplarily illustrates that the first light-cutoff region 150a covers portion of the first active display layer 140a and portion of the second active display layer 140b along the cross-sectional direction of the glass body, and the second light-cutoff region 150b covers portion of the second active display layer 140b and portion of the first active display layer 140a along the cross-sectional direction of the glass body. Optionally, the first light-cutoff region 150a covers portion of the first active display layer 140a or covers or substantially covers the entire first active display layer 140a and covers portion of the second active display layer 140b along the cross-sectional direction of the glass body, and the first light-cutoff region 150a and the second light-cutoff region 150b jointly cover or jointly substantially cover the entire second active display layer 140b along the cross-sectional direction of the glass body or the second light-cutoff region 150b covers portion of the second active display layer 140b but not covers the first active display layer 140a along the cross-sectional direction of the glass body; or optionally, the second light-cutoff region 150b covers portion of the second active display layer 140b or covers or substantially covers the entire second active display layer 140b and covers portion of the first active display layer 140a along the cross-sectional direction of the glass body, and the first light-cutoff region 150a and the second light-cutoff region 150b jointly cover or jointly substantially cover the entire first active display layer 140a along the cross-sectional direction of the glass body or the first light-cutoff region 150a covers portion of the first active display layer 140a but not covers the second active display layer 140b along the cross-sectional direction of the glass body. By using the glass assembly 200-1 shown in FIG. 7 and some variations thereof, the image display effect with enhanced contrast toward different sides of the glass assembly 200-1 can also be obtained by switching different light-cutoff regions between the dark state and the non-dark state in combination with corresponding portions of the first active display layer 140a and / or the second active display layer 140b displaying images. In addition, in the embodiment shown in FIG. 7 and some variations thereof, one light-cutoff region can cover portions of a plurality of active display layers at the same time, which can further obtain some display effects while ensuring the above effects required to be obtained by the glass assembly. For example, when the first light-cutoff region 150a is switched to the dark state, in addition that the portion of the first active display layer 140a corresponding to the first light-cutoff region 150a can obtain the image display effect with enhanced contrast to the inside of the vehicle, for the corresponding portion of the second active display layer 140b simultaneously covered by the first light-cutoff region 150a in the cross-sectional direction of the glass assembly, the image display effect with enhanced contrast can also be obtained, and thus the application mode is more diversified.
[0089] Similarly, in some variations of the glass assembly 200-1 of the embodiment shown in FIG. 7, a plurality of light-cutoff layers may also be arranged on two sides of at least one active display layer. For example, the light-cutoff layer 150 in FIG. 7 may be replaced with an active display layer, the first active display layer 140a may be replaced with a first light-cutoff layer, and the second active display layer 140b may be replaced with a second light-cutoff layer. In this variation, in the cross-sectional direction of the glass assembly, the first light-cutoff layer and the second light-cutoff layer are overlapped with each other and partially overlapped with each other. According to different requirements, the first light-cutoff layer and / or the second light-cutoff layer jointly or individually cover or jointly or individually substantially cover the entire at least one active display layer along the cross-sectional direction of the glass body; and / or the first light-cutoff layer covers portion of the at least one active display layer or covers or substantially covers the entire at least one active display layer along the cross-sectional direction of the glass body, and / or the second light-cutoff layer covers portion of the at least one active display layer or covers or substantially covers the entire at least one active display layer along the cross-sectional direction of the glass body. By switching one or more light-cutoff regions of different light-cutoff layers between the dark state and the non-dark state, the image display effect with enhanced contrast toward different sides of the glass assembly can also be obtained.
[0090] FIG. 8 exemplarily illustrates a glass assembly 200-2 according to another embodiment, which differs from the embodiment shown in FIG. 7 in that the first active display layer 140a and the second active display layer 140b are completely overlapped in the cross-sectional direction of the glass assembly 200-2. The first light-cutoff region 150a and the second light-cutoff region 150b jointly cover or jointly substantially cover the entire first active display layer 140a along the cross-sectional direction of the glass body, and the first light-cutoff region 150a and the second light-cutoff region 150b jointly cover or jointly substantially cover the entire second active display layer 140b along the cross-sectional direction of the glass body. For the embodiment shown in FIG. 8, the first light-cutoff region 150a and the second light-cutoff region 150b jointly substantially cover the entire first active display layer 140a along the cross-sectional direction of the glass body, and the first light-cutoff region 150a and the second light-cutoff region 150b jointly substantially cover the entire second active display layer 140b along the cross-sectional direction of the glass body. In this case, the first light-cutoff region 150a may be switched to the dark state, so that the portion of the first active display layer 140a corresponding to the first light-cutoff region 150a provides, for example, the image display effect with enhanced contrast toward the inside of the vehicle, provides the privacy effect of image content, and reduces the influence on people outside the vehicle. Optionally, while the first light-cutoff region 150a is switched to the dark state, the second light-cutoff region 150b may be kept in the non-dark state to meet the requirements of observation field of view of the driver or the passenger or not adversely affect the image display effect of the portion of the first active display layer 140a corresponding to the second light-cutoff region 150b, and the second light-cutoff region 150b may also be switched to the dark state to provide the privacy effect inside the vehicle or enable the portion of the first active display layer 140a corresponding to the second light-cutoff region 150b to simultaneously provide the image display effect with enhanced contrast toward the inside of the vehicle, provide the privacy effect of the image content, and reduce the influence on people outside the vehicle. For the second active display layer 140b, similar effects may also be achieved by switching the first light-cutoff region 150a and / or the second light-cutoff region 150b between the dark state and the non-dark state, which will not be repeated 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 region 150a and the second light-cutoff region 150b to the dark state, the image display effect with enhanced contrast toward both the inside of the vehicle and the outside of the vehicle can be obtained, and the influence of the image content on people inside and outside the vehicle can be reduced.
[0091] It should be understood that the layer composed of the first active display layer 140a and the second active display layer 140b and the light-cutoff layer 150 in FIG. 8 are shown to have substantially 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-cutoff layer 150 may also be provided with a picture frame structure.
[0092] Similarly, in some variations of the glass assembly 200-2 of the embodiment shown in FIG. 8, a plurality of light-cutoff layers may also be arranged on two sides of at least one active display layer. For example, the light-cutoff layer 150 in FIG. 8 may be replaced with an active display layer, the first active display layer 140a may be replaced with a first light-cutoff layer, and the second active display layer 140b may be replaced with a second light-cutoff layer. In this variation, in the cross-sectional direction of the glass assembly, the first light-cutoff layer and the second light-cutoff layer are overlapped with each other and completely overlapped with each other. The first light-cutoff layer and the second light-cutoff layer individually cover or individually substantially cover the entire at least one active display layer along the cross-sectional direction of the glass body. That is, the first light-cutoff layer covers or substantially covers the entire at least one active display layer along the cross-sectional direction of the glass body, and the second light-cutoff layer covers or substantially covers the entire at least one active display layer along the cross-sectional direction of the glass body. By switching one or more light-cutoff regions of different light-cutoff layers between the dark state and the non-dark state, the image display effect with enhanced contrast toward different sides of the glass assembly can also be obtained.
[0093] It should be understood that, in the exemplary embodiments of FIG. 6 to FIG. 8, similarly, the interval between the first light-cutoff region 150a and the second light-cutoff region 150b adjacent to each other corresponding to the first active display layer 140a and the second active display layer 140b 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 when the interval is, for example, less than or equal to 0.1 mm, the gap can be invisible to naked eyes to ensure aesthetics. It should be understood that, depending on different requirements, the first active display layer and the second active display layer may be staggered from each other and arranged in different regions of the glass assembly, and preferably, the first active display layer and the second active display layer are arranged on two sides of at least one light-cutoff layer, and accordingly, the interval between the first light-cutoff region and the second light-cutoff region is not limited. Preferably, in the case of a plurality of first light-cutoff regions corresponding to at least portion of one first active display layer or at least portion of each first active display layer of a plurality of first active display layers and / or a plurality of second light-cutoff regions corresponding to at least portion of one second active display layer or at least portion of each second active display layer of a plurality of second active display layers, the interval between the plurality of first light-cutoff 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-cutoff 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 is true for the case of a plurality of light-cutoff layers, that is, the intervals between a plurality of light-cutoff regions adjacent to each other of the plurality of light-cutoff layers are also configured as such, for example, preferably, for one or more light-cutoff regions arranged in different light-cutoff layers, the interval between a plurality of light-cutoff regions adjacent to each other corresponding to at least portion of one active display layer or at least portion of active display layers adjacent to each other of a plurality of 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] FIG. 9 exemplarily illustrates an embodiment in which the light-cutoff layer 150 substantially covers the entire active display layer 140, and the glass assembly 100 shown in FIG. 1 is used as an example. It should be understood that although the active display layer 140 and the first light-cutoff region 150a, the second light-cutoff region 150b and the third light-cutoff region 150c of the light-cutoff layer 150 in FIG. 9 are all shown as substantially rectangular, on the premise of satisfying the concept of the present disclosure, the active display layer, the light-cutoff layer, and the light-cutoff region herein encompass any appropriate shape, including but not limited to square, triangle, sector, other patterns with curved edges or straight edges, etc. It should be understood that light-cutoff regions with different shapes or sizes and / or different numbers of light-cutoff regions and / or the size of the light-cutoff region covering the active display layer may be determined according to the shape or size of the region where the image needs to be displayed and / or the shape or size of the region where the corresponding effect needs to be provided.
[0095] When the glass assembly is applied as, for example, front windshield, rear windshield or corner window glass, the glass assembly is adapted to cooperate with a sealing strip when the glass assembly is mounted to a vehicle and in a fully used state of the glass assembly. When the glass assembly is applied as a vehicle door glass, the glass assembly is adapted to cooperate with a water cutting strip (also belongs to the sealing strip) , such as the water cutting strip 170 exemplarily shown in FIGS. 10-12, when the glass assembly is mounted to the vehicle and in the fully used state of the glass assembly (i.e., the vehicle door glass window is completely closed) . The water cutting strip refers to a rubber sealing strip between the vehicle door glass and a vehicle door frame at the bottom of the vehicle door glass, and is used to cut off water droplets, water mist and dust on the glass surface when raising or lowering the vehicle door glass, and also play an aesthetic role, for example, the connection wires and control wires of the active display layer 140 and the light-cutoff layer 150 can be hidden below the sealing strip without being observed.
[0096] In some embodiments, the glass assembly comprises a control unit comprising vehicle control unit and / or remote control unit and / or electronic control unit of the active display layer and / or electronic control unit of the light-cutoff layer. The control unit may be configured to: acquire an instruction of a region for displaying an image of the active display layer, or determine the region for displaying an image of the active display layer; make at least one light-cutoff region of the light-cutoff layer corresponding to the region for displaying an image of the active display layer in the dark state, or make the at least one light-cutoff region in the non-dark state, in response to the region for displaying an image of the active display layer displaying the image. It should be understood that the control unit herein may include independent control units separated at different physical locations, or may include an integrated control unit integrated at a same physical location.
[0097] In some embodiments, the glass assembly may comprise a human-computer interaction unit, the control unit at least comprises an electronic control unit of the human-computer interaction unit, and the electronic control unit of the human-computer interaction unit is configured to determine the region for displaying an image of the active display layer; optionally, the control unit further comprises vehicle control unit and / or remote control unit and / or electronic control unit of the active display layer and / or electronic control unit of the light-cutoff layer.
[0098] In a manner in which the glass assembly includes the human-computer interaction unit, the human-computer interaction unit may be communicatively connected to the glass assembly via an external interface and / or a wireless transceiver, to sense, for example, including but not limited to touch information and / or voice information and / or motion information, wherein the motion information includes, for example, but not limited to gesture and / or posture and / or motion. Optionally, the human-computer interaction unit may include contact interaction unit or non-contact interaction unit. Accordingly, the glass assembly may include a functional layer such as a touch layer (e.g., a capacitive touch film) , and the function of the touch layer is well known in the art and will not be elaborated here. The non-contact interaction unit may be configured to be near an edge of the glass body and arranged on and / or near a surface of the glass body. For the non-contact interaction manner, because a touch layer does not need to be arranged, the glass assembly can have relatively higher light transmittance and transparency. Optionally, the non-contact interaction unit comprises proximity sensor and / or distance sensor and / or image sensor. Preferably, the proximity sensor may be ultrasonic sensor or infrared sensor, and the distance sensor may be laser ranging sensor or ultrasonic ranging sensor or infrared ranging sensor. Preferably, the distance sensor may be a time-of-flight (TOF) sensor. It should be understood that the non-contact interaction units exemplarily listed above may be used independently, or may be combined with each other or integrated with related components. For example, according to different requirements, the human-computer interaction unit may be configured as a camera with an image sensor, such as a CCD camera, that is, a digital camera with a charge coupled device image sensor. In addition, the working principle of the non-contact interaction unit exemplarily listed above is known to those skilled in the art and will not be elaborated here.
[0099] It should be understood that, for the motion information, the gesture refers to a specific motion and body position presented when a person uses an arm, for example, a specific hand posture formed by positions and shapes of a palm and fingers. The posture refers to the way the human body appears. The motion encompasses the movement or action of the human body, and includes, for example, a process of a change in positions of facial features (that is, an expression change) , a change in positions of limbs of the human body (that is, a motion change) , or a change in relative positions of the human body and the environment (that is, a relative position change) . It should be understood that the above exemplary listed motion information and the working principle of providing the information are known to those skilled in the art and will not be elaborated here.
[0100] According to different requirements, a plurality of light-cutoff regions of one light-cutoff layer or one or more light-cutoff regions of each light-cutoff layer of a plurality of light-cutoff layers and / or corresponding portions of one or more active display layers may be individually controlled, so that, for example, various adjustment functions such as segmented display, dynamic display and flow display, etc. may be realized, thereby meeting different functional requirements of users. FIG. 10 to FIG. 12 respectively exemplarily illustrate the cases in which the glass assembly in any form in FIG. 1 to FIG. 8 is applied to the vehicle door glass.
[0101] Referring to FIG. 10 first, the glass assembly 100-1 shown in FIG. 2 is taken as an example. The glass assembly 100-1 is usually placed in a substantially vertical direction after being mounted to the vehicle, and the arrow in the figure indicates a direction toward the head of the vehicle, that is, the first light-cutoff region 150a, the second light-cutoff region 150b and the third light-cutoff region 150c are sequentially arranged from the front of the vehicle to the rear of the vehicle. In this embodiment, the first light-cutoff region 150a is switched to the dark state, the corresponding portion of the active display layer 140 displays an image 180, and the displayed image 180 has enhanced contrast or clarity. Since the active display layer 140 is closer to the second glass body facing the inside of the vehicle than the light-cutoff layer, the image display effect inside the vehicle is improved. In this way, in some occasions, the image 180 can be displayed only on the region of the vehicle door glass close to the front of the vehicle, so as to meet the requirement of the driver and the passenger to observe the image in an ergonomic design, and meanwhile, the remaining region (the second light-cutoff area 150b and the third light-cutoff area 150c) of the vehicle door glass is still remained in the non-dark state, so as to meet the requirement of the driver and the passenger to observe the outside of the vehicle. In addition, since the first light-cutoff region 150a corresponding to the portion of the active display layer 140 that displays the image 180 is in the dark state, the privacy protection of the image content can be further provided and the influence on people outside the vehicle can be reduced. It should be understood that similar effects described above can also be obtained for the glass assemblies of the embodiments shown in FIGS. 1 and 4 or FIGS. 5 to 8 and the glass assemblies not shown based on the concept of the present disclosure.
[0102] In an embodiment shown in FIG. 11, the glass assembly 100-2 shown in FIG. 3 is taken as an example. In this embodiment, the third light-cutoff region 150c is switched to the dark state, the corresponding portion of the active display layer 140 displays the image 180, and 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-cutoff layer, the image display effect outside the vehicle is improved. In this way, in some occasions, the image 180 can be displayed only on the region of the vehicle door glass close to the rear of the vehicle, so as to meet the requirement of people outside the vehicle to observe the image, realize information interaction between the inside and outside the vehicle and reduce the influence of the displayed image on people inside the vehicle, and meanwhile, the remaining region (the first light-cutoff area 150a and the second light-cutoff area 150b) of the vehicle door glass is still remained in the non-dark state, so as to meet the requirement of the driver and the passenger to observe the outside of the vehicle. It should be understood that similar effects described above can also be obtained for the glass assemblies of the embodiments shown in FIGS. 5 to 8 and the glass assemblies not shown based on the concept of the present disclosure.
[0103] In an embodiment shown in FIG. 12, the glass assembly 100-1 shown in FIG. 2 is still taken as an example. In this embodiment, the first light-cutoff region 150a, the second light-cutoff region 150b and the third light-cutoff region 150c are all switched to the dark state, that is, substantially the entire active display layer 140 can be used to display the image 180 toward the inside of the vehicle. Certainly, it is also possible to display the image only in the portion corresponding to each light-cutoff region and provide the privacy effect inside the vehicle through the remaining light-cutoff regions that maintain the dark state according to different requirements. This case can be applied to, for example, rear vehicle door glass, or front vehicle door glass in a non-driving state, or front vehicle door glass when an in-vehicle electronic rearview mirror is installed. In some cases, the first light-cutoff region 150a, the second light-cutoff region 150b and the third light-cutoff region 150c may also all be switched to the non-dark state, so that the effect of displaying images by the active display layer 140 is not adversely affected. It should be understood that similar effects described above can also be obtained for the glass assemblies of the embodiments shown in FIG. 1, FIG. 3 to FIG. 8 and the glass assemblies not shown based on the concept of the present disclosure based on different requirements.
[0104] Regardless of the arrangement and combination manner, the glass assembly of the present disclosure advantageously provides the image display function with enhanced contrast, the privacy function of the image content on the image display side, and the reduction function of adverse effects on the non-image display side in different regions according to different requirements, which brings rich and comfortable user experience. It should be understood that in the described or undescribed possible embodiments, various improvements may be used independently or in combination with each other, so that the glass assembly of the present disclosure can be applied to various occasions to meet the diversified requirements of users.
[0105] The present disclosure further provides a display method for controlling a glass assembly to display an image and a computer device for implementing the display method. With reference to FIG. 13, a computer device 300 (referred to as device 300 for short) for implementing the display method provided by the present disclosure may include a memory 310 and a processor 320, computer-executable instructions 311 (referred to as instructions 311 for short) may be stored in the memory 310, the instructions 311 may be executed by the processor 320, and the processor 320 implements the display method when executing the instructions 311.
[0106] In some embodiments, the device 300 may be a device such as vehicle control device, remote control device (for example, notebook computer, desktop computer, mobile phone or cloud server) , the active display layer control device, the light-cutoff layer control device, or the human-computer interaction unit, etc. It can be understood that the components included in the device 300 are not limited to the memory 310 and the processor 320, and may vary depending on different requirements. Exemplarily, the device 300 may further include a plurality of components (not shown) connected to its input / output interfaces, including but not limited to: an input unit, such as keyboard, mouse, etc. ; an output unit, such as various types of displays, speakers, the active display layers, the light-cutoff layers, etc. ; a storage unit, such as semiconductor storage device, magnetic surface storage device and optical storage device, etc. ; and a communication unit, such as network card and wireless communication transceiver, etc. The communication unit allows the device to exchange information / data with other devices through a computer network such as the Internet and / or various telecommunication networks.
[0107] In some embodiments, the memory 310 may include, for example, random access memory (RAM) or read-only memory (ROM) . The memory 310 may be configured to store instructions, programs, codes, and other programs and data required by the device 300, but is not limited thereto. In addition, the processor 320 may be a central processing unit (CPU) , or may be another general-purpose processor, for example, digital signal processing (DSP) , field programmable gate array (FPGA) , or programmable logic array (PLA) .
[0108] Specifically, the display method of the present disclosure is used to control the above glass assembly to display an image, and as shown in FIG. 14, the exemplary display method may include:
