GLASS ASSEMBLY, DISPLAY METHOD, DISPLAY SYSTEM AND MEANS OF TRANSPORTATIONFIELD
[0001] The present disclosure relates generally to the technical field of glass manufacturing, and in particular to a glass assembly, a display method applied to the glass assembly, a display system applying the glass assembly, a computer device for implementing the display method, a means of transportation including the glass assembly or the display system or the computer device, a computer-readable storage medium and a computer program product.BACKGROUND
[0002] With the rapid development of the automotive industry, vehicle window glass has been increasingly used as a display screen to provide information display, such as image, etc., to occupants (driver and passenger) inside the vehicle and / or personnel outside the vehicle. In the current design trend, vehicle manufacturer tends to provide a pillar-to-pillar (A-pillar to A-pillar) immersive display system (e.g., a heads-up display system, HUD, or an augmented reality heads-up display system, AR-HUD) , which reduces the attention redirection required by the driver to shift from the view of the road to a display screen that is typically located below the field of view by displaying an image at a front windshield, providing a safer driving experience.
[0003] Usually, a display element for providing the image is arranged at a dashboard close to the front windshield, and the image is projected to the front windshield by specular reflection imaging. Due to constraints in the mounting location and mounting space of the display element, there are significantly visible and large spaces between display regions of a plurality of display elements in the dashboard. Additionally, for example, virtual image distance (VID, a visual distance from a virtual image to human eyes) , angle of vision, and a position of the human eyes all determine the accuracy and comfort of the displayed image, while the position of the human eyes of the occupant inside the vehicle will dynamically change with the height, sitting posture and head position of the occupant, thereby also significantly affecting the display effect. Therefore, the vehicle manufacturer and consumer desire to adjust or improve existing display interaction interfaces.SUMMARY

[0061] 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.
[0062] 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.
[0063] 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.
[0064] 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.
[0065] In this context, the meaning of "aplurality of" refers to two or more than two, unless otherwise specified.
[0066] 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, "edge" is a surface defined by a thickness in all surfaces of the glass body or each laminated layer structure, "length" is a distance with a larger dimension along an extension direction in the surface of the glass body or each laminated layer structure, and "width" is a distance extending in a direction perpendicular to the length direction in the surface 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.
[0067] Hereinafter, 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 a direction away from the vehicle body, "inside" refers to a 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 embodiments of the present disclosure is described by taking a front windshield as an example, but it is not excluded that it is applied to the vehicle window glass including but not limited to rear windshield glass, skylight glass, vehicle door glass or corner window glass, which can provide different display effects based on different requirements.
[0068] In the various described embodiments, unless otherwise specified, the thickness of the glass body is the thickness commonly used in the art, and the thickness of each laminated structure on the glass body is within 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 cases not described, special coatings may also be used on the surface of the glass body to improve other properties such as thermal insulation and / or comfort.
[0069] For manufacturers and most vehicle users, it is desirable to use vehicle window glass to achieve various forms of image display effects, and the current pillar-to-pillar immersive display system provides safer driving experience by displaying an image at a front windshield. In some more preferred solutions, through arranging a display element (for example, a display element that emits P-polarized light) at a dashboard close to the front windshield, and adding a special coating to a surface of the front windshield, a black ink area that is originally only used to cover a mounting mark is converted into a projection display interface, so that driving and safety related information (for example, vehicle speed information, danger prompt, distance warning, turning prompt, vehicle charging prompt, and telephone call prompt, etc. ) is provided in an area as close as possible to the line of sight of a driver and a passenger, and displayed image is clearer and has high contrast. However, the inventors found that due to the constraints on mounting position and mounting space of the display element, there are always significantly visible and large spaces between image display regions of a plurality of display elements in the dashboard, and thus a continuous image from pillar to pillar in the length direction (from left to right) of the front windshield cannot be formed.
[0070] To this end, according to the concept of the present disclosure, a glass assembly is provided. The glass assembly comprises: a glass body comprising a first glass body and a second glass body stacked and attached to each other by an adhesive layer; a shielding layer arranged between the first glass body and the second glass body; a reflective layer arranged on a surface of the first glass body away from the second glass body, or arranged on a surface of the second glass body away from the first glass body, or arranged between the first glass body and the second glass body to display a pattern and / or an image by reflection, wherein the reflective layer is at least partially located in the shielding layer along a cross-sectional direction of the glass body; and a light-emitting layer arranged between the shielding layer and the reflective layer, between the first glass body and the second glass body, wherein the light-emitting layer is located in the shielding layer along the cross-sectional direction of the glass body.
[0071] In the glass assembly of the present disclosure, a reflective interface for displaying a pattern and / or an image is provided by the reflective layer, and since the reflective layer is at least partially located in the shielding layer along the cross-sectional direction of the glass body, that is, the reflective interface provided by the reflective layer is at least partially located in a shielding region bounded by the shielding layer, the shielding layer can provide improved definition and contrast for the display effect of the pattern and / or the image, meanwhile, the display effect of the light (including the effect of the light for illumination) can be provided by the light-emitting layer, allowing the display effect of the light and the display effect of the pattern and / or the image provided by the reflective layer to be accumulated, so that the light emitted by the light-emitting layer can be used to form a continuous display interface to compensate for the space between the pattern and / or the image formed by reflection. The light emitted by the light-emitting layer is fixed relative to the position of an observer’s eyes, and thus it can provide a continuous visual effect with fixed position without being affected by the change of the position of the observer’s eyes. In addition, due to the shielding effect of the shielding layer, the light-emitting layer can be well hidden from the user, and the external appearance is beautiful. Further, while the light is provided through the light-emitting layer, the design and control of the light-emitting layer (for example, the color and / or light intensity and / or lighting time of the light, etc. ) can also be combined to achieve a multi-level illumination display effect (for example, a plurality of colours, gradient colours, segmented colours, etc. ) , and a changed display effect of dynamic / static patterns (for example, flowing water, flashing, breathing, etc. ) can be achieved, thereby further enriching the display effect of the light and meeting the requirements of some specific scene atmospheres. For example, the color and brightness of the light can be changed according to different driving scenes and operations, so that driving information and other prompts can be provided. In this way, the glass assembly with multiple functions can provide a richer and diversified display effect for the vehicle occupant, thereby improving the user's use atmosphere and experience comfort. For example, when the display effect of light emission is achieved by the light-emitting layer alone, the light color can be changed according to different driving scenes such as acceleration, deceleration, turning, etc., to provide the driver with intuitive information feedback and increase driving safety; when the light emitted by the light-emitting layer is combined with the display effect of the pattern and / or the image provided by the reflective layer to implement, for example, a navigation function, the light of the light-emitting layer can flash as the route changes, allowing the driver to see the driving route at a glance.
[0072] In this context, there is no limitation on the pattern or image displayed through reflection by the reflection layer, for example, it can be text, numbers, symbols or pictures, and the image can also be dynamic video. The light-emitting layer can also be designed according to different requirements, so that the emitted light can display, for example, text, numbers, symbols, etc., in addition to providing line display, which is not limited herein.
[0073] FIG. 1 exemplarily illustrates a schematic cross-sectional view of a glass assembly according to an embodiment of the present disclosure. In this embodiment, a glass assembly 100 comprises a first glass body 110 and a second glass body 120, and an adhesive layer 130 attaching the first glass body 110 and the second glass body 120 to each other. A shielding layer 140 is arranged between the first glass body 110 and the second glass body 120, and defines a shielding region on the surface of the glass assembly. Here, "between" encompasses various arrangements in which the shielding layer is directly adjacent to or not directly adjacent to the first glass body 110 or the second glass body 120. It should be understood that, "shielding" means blocking, covering, or hindering an object from being seen or perceived by human eyes. When the glass assembly is applied to a vehicle window glass, a visible light transmittance of a material used for the shielding layer may be less than or equal to 5%, less than or equal to 4%, less than or equal to 2%, less than or equal to 1%, less than or equal to 0.5%, less than or equal to 0.1%, or 0%, for example, the material may be selected as tinted enamel or tinted adhesive film. In this context, "tinted" refers to the inherent color in the material in a natural state (for example, it is not electrically variable) comprising naturally tinted or added with color through a process, such as black or grey. A reflective layer 150 may be arranged on a surface of the first glass body away from the second glass body, or arranged on a surface of the second glass body away from the first glass body, or arranged between the first glass body and the second glass body according to different requirements, so as to display a pattern and / or an image by reflection. Similarly, "between" herein encompasses various arrangements in which the reflective layer is directly adjacent to or not directly adjacent to the first glass body 110 or the second glass body 120. In addition, the reflective layer is at least partially located in the shielding layer along the cross-sectional direction of the glass body, advantageously, the reflective layer is completely located in the shielding layer, and the reflective layer is located in the shielding region of the shielding layer and covered or blocked by the shielding layer. When applied to the vehicle window glass, the first glass body 110 may face the outside of the vehicle, which may be called outer glass, and the second glass body 120 may face the inside of the vehicle, which may be called inner glass. In the illustrated embodiment, the shielding layer 140 may be specifically arranged between the first glass body 110 and the adhesive layer 130, and the reflective layer 150 may be arranged on the surface of the second glass body 120 away from the first glass body 110, that is, the reflective layer is closer to the interior of the vehicle than the shielding layer. In some embodiments, the reflective layer 150 may also be arranged on the surface of the second glass body 120 facing the first glass body 110 according to different requirements. When a display unit projects a pattern and / or an image to the reflective layer 150 (for example, from the lower side of the orientation shown in FIG. 1) , the projected light is reflected at the reflective layer to form a virtual image, and due to the existence of the shielding layer 140, the projected light is not transmitted from the first glass body 110 to the outside of the glass assembly, thereby improving the definition and contrast of the virtual image observed from the side of the reflective layer 150.
[0074] For the reflective layer 150, it may be in the form of, for example, reflective coating or reflective film based on different requirements, as long as it can provide, for example, a specular reflection effect, which is not limited herein. It should be understood that, depending on different requirements, one or more adhesive layers may be arranged between the first glass body 110 and the second glass body 120. As an example, the adhesive layer 130 is, for example, an adhesive layer suitable for the laminated glass such as polyvinyl butyral (PVB) , ethylene-vinyl acetate (EVA) , optically clear adhesive (OCA) , and polyurethane (PU) . In an embodiment in which the shielding layer 140 is selected as a tinted adhesive film, a material of the adhesive film may be the same as a material of the adhesive layer, for example, it can be selected as tinted PVB film or tinted EVA film.
[0075] In the embodiment shown in FIG. 1, a light-emitting layer 160 is also shown, which is arranged between the shielding layer 140 and the reflective layer 150 and located in the shielding layer along the cross-sectional direction of the glass body. Similarly, "between" here encompasses various arrangements in which the light-emitting layer is directly adjacent to or not directly adjacent to the shielding layer or the reflective layer. For example, in the illustrated embodiment, the light-emitting layer 160 may be specifically arranged between the second glass body 120 and the adhesive layer 130. In this context, "light-emitting layer" refers to a layer structure that can emit light by itself when powered without a light source. For example, it comprises a light-emitting diode (LED) , and preferably an addressable LED, which can not only provide more lighting effects, but also achieve more complex animations and interactive effects. Advantageously, the light-emitting diode may be organic light-emitting diode (OLED) or mini light-emitting diode (Mini LED) or micro light-emitting diode (Micro-LED or μLED) . Further, the light-emitting layer 160 may be located in the reflective layer 150 along the cross-sectional direction of the glass body, and with respect to an observer, the light-emitting layer is hidden behind the reflective layer. Advantageously, the reflective layer 150 is configured to allow the light emitted by the light-emitting layer 160 to pass through. In this way, while providing the reflective interface for displaying the pattern and / or the image through the reflective layer, the glass assembly of the present disclosure also utilizes the light-emitting layer to provide the display effect of the light, which allows the display effect of the light and the display effect of the pattern and / or the image provided by the reflective layer to be accumulated (the combination of the display effect of the pattern and / or the image provided by the reflective layer and the display effect of the light provided by the light-emitting layer) , thereby forming a continuous display interface without spaces. The light-emitting layer may be individually controlled and adjusted independently of the display unit for projecting the pattern and / or the image to the reflective layer. In addition, unlike the limited mounting layout of the display element in the prior art, the arrangement of the light-emitting layer on the glass assembly is easy to implement, and the light-emitting layer itself and / or the light emitted by the light-emitting layer is visually continuous without obvious spaces. Optionally, the light-emitting layer can occupy most of the length or even the entire length or most of the width or even the entire width of the glass assembly along the length direction or the width direction of the glass assembly, and accordingly, the light emitted by the light-emitting layer and / or the light-emitting layer is visually continuous along the most of the length or even the entire length or the most of the width or even the entire width of the glass assembly. For example, when the light-emitting layer is arranged along the most of the length or the entire length of the front windshield, correspondingly, the light emitted by the light-emitting layer and / or the light-emitting layer can be visually continuous along the most of the length or the entire length of the front windshield, so as to achieve a real continuous display effect from pillar to pillar.
[0076] Alternatively, a visible light transmittance of the reflective layer may be 5%to 20%, for example, in some embodiments, the visible light transmittance of the reflective layer may be 9%, 12%, 15%, or 18%, etc. 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) .
[0077] Advantageously, the light-emitting layer is configured to be arranged along a contour of the shielding layer and / or along a contour of the reflective layer. For example, when the glass assembly is applied to the front windshield, the front windshield is usually placed at an angle to a vertical direction when the front windshield is mounted to a vehicle and in a use state, and the shielding layer is located at a lower edge of the front windshield in the use state. The reflective layer displays the pattern and / or the image by reflection, and the light-emitting layer is arranged along the contour of the shielding layer and / or the reflective layer, which is beneficial to optimize the display effect presented in the shielding region, so that the display interface is visually integrated and has wide-angle readability, improving the use comfort of the observer.
[0078] In order to further prevent the light emitted by the light-emitting layer from leaking from the undesired surface to the outside of the glass assembly, in some embodiments, as shown in FIG. 2, a glass assembly 100-1 of an embodiment may further include a light-shielding layer 170 located in the shielding layer 140 along the cross-sectional direction of the glass body and arranged between the light-emitting layer 160 and the shielding layer 140. The light-shielding layer 170 covers the light-emitting layer 160 along the cross-sectional direction of the glass body to shield the light emitted by the light-emitting layer 160 toward the shielding layer 140. According to different requirements, the material of the light-shielding layer 170 and the material of the light-shielding layer 140 may be the same or different, as long as the visible light transmittance of the light-shielding layer is low. Advantageously, a visible light transmittance of the light-shielding layer 170 may be less than or equal to 5%, less than or equal to 4%, less than or equal to 2%, less than or equal to 1%, less than or equal to 0.5%, less than or equal to 0.1%, or 0%. In some embodiments, the light-shielding layer 170 may include a tinted adhesive film, and a material of the adhesive film may be the same as a material of the adhesive layer, for example, it can be selected as tinted PVB film or tinted EVA film. It should be understood that when the shielding layer 140 adopts, for example, a tinted PVB with a visible light transmittance of 0%, the light-shielding layer may not be used between the light-emitting layer and the shielding layer. When, for example, a tinted PVB is used as the light-shielding layer 170, if PVB is used for the remaining portions of the adhesive layer located in the shielding layer along the cross-sectional direction of the glass body, the PVB of these portions may be transparent and can be fused with the tinted PVB used as the light-shielding layer during the lamination process of the glass assembly. In some cases, when the thickness of the shielding layer 140 may serve as the primary adhesive layer for the glass assembly, the illustrated adhesive layer 130 may also be removed. In this case, when the glass assembly is applied as the front windshield, the adhesive layer (not shown in the figure) corresponding to the visible area of the front windshield may be transparent and may be combined with the shielding layer 140 as a single adhesive layer. That is, the shielding layer 140 and the adhesive layer corresponding to the visible area may be in the form of a PVB with segmented tinting. Similarly, when the light-shielding layer 170 is tinted PVB, the adhesive layer 130 may be combined with the light-shielding layer 170 to form a single adhesive layer, that is, a PVB adhesive layer with segmented tinting may be used. In the following embodiments, the same or similar designs may be adopted according to different requirements.
[0079] In a glass assembly 200 of an embodiment shown in FIG. 3, in addition to the light-shielding layer 170, a light-diffusion layer 180 located in the shielding layer 140 along the cross-sectional direction of the glass body and arranged between the light-emitting layer 160 and the reflective layer 150 is also shown, and the light-diffusion layer may be arranged adjacent to the light-emitting layer or spaced apart from the light-emitting layer according to different requirements. The light-diffusion layer 180 contributes to the transmission and output of the light, for example, it is used to limit and / or guide the output intensity of the light and / or the angle of the light, and is conducive to converting a point or line light source into a soft and uniform surface light source, achieving a soft and uniform display effect and improving the visual comfort of the observer. In the embodiment shown in FIG. 3, the light-diffusion layer 180 is arranged adjacent to the light-emitting layer 160. For example, a first adhesive layer 130a and a second adhesive layer 130b are arranged between the first glass body 110 and the second glass body 120, the light-emitting layer 160, the light-shielding layer 170 arranged between the light-emitting layer 160 and the shielding layer 140, and the light-diffusion layer 180 arranged between the light-emitting layer 160 and the reflective layer 150 may be sandwiched between the first adhesive layer 130a and the second adhesive layer 130b. Optionally, in a glass assembly 200-1 of an embodiment shown in FIG. 4, the light-diffusion layer 180 may be arranged to be spaced apart from the light-emitting layer 160, that is, the second adhesive layer 130b may be sandwiched between the light-diffusion layer 180 and the light-emitting layer 160. In addition, depending on the material or structural design of the light-diffusion layer 180, the light-diffusion layer 180 and the second glass body 120 may be directly attached or attached via another adhesive layer.
[0080] Advantageously, the light-diffusion layer 180 covers the light-emitting layer 160 along the cross-sectional direction of the glass body (the first glass body and the second glass body) . Here, "cover" means that the orthographic projection of the light-diffusion layer 180 covers the orthographic projection of the light-emitting layer 160 along the cross-sectional direction of the glass body, that is, the size or area of the orthographic projection of the light-diffusion layer is greater than or equal to the size or area of the orthographic projection of the light-emitting layer, so that the light-diffusion layer can fully diffuse (for example, by scattering) the light emitted by the light-emitting layer to acquire a uniform illumination display effect.
[0081] In some embodiments, the glass assembly may further include a picture frame structure arranged around the light-emitting layer and / or the light-diffusion layer. For example, in a glass assembly 200-2 of an embodiment shown in FIG. 5, a picture frame structure 170a may be arranged around the light-diffusion layer 180 (exemplarily shown on the right side of the light-diffusion layer 180 in the figure) . The picture frame structure 170a may achieve pre-positioning of the light-diffusion layer 180, fill the thickness difference between the edge of the light-diffusion layer 180 and the adhesive layer, thereby ensuring complete sealing after lamination. Alternatively, the picture frame structure may be selected to be the same material as the adhesive layer mentioned above. When the thickness of the light-diffusion layer 180 is sufficiently small, the picture frame structure may also be omitted. The picture frame structure may be transparent or tinted according to different requirements. Advantageously, in some embodiments, the picture frame structure 170a located in the shielding layer 140 along the cross-sectional direction of the glass body may be selected as a tinted material. For example, in this embodiment, the picture frame structure 170a may be selected as the same material as the light-shielding layer 170, such as tinted PVB, meanwhile, an adhesive layer 130c located in the shielding layer 140 along the cross-sectional direction of the glass body may also be tinted PVB, so as to prevent the light emitted by the light-emitting layer 160 from exiting the glass assembly from the area not covered by the light-diffusion layer 180. It should be understood that when the glass assembly is applied as the front windshield, the adhesive layer corresponding to the visible area of the front windshield may be transparent, that is, in the embodiment shown in FIG. 5, a PVB with segmented tinting may be used.
[0082] Alternatively, the transmission of the light emitted by the light-emitting layer toward the specific region in the glass assembly may also be acquired by changing the light transmission path. In some embodiments, the light emitted by the light-emitting layer may not be directly transmitted toward the side of the reflective layer, but is reflected and / or refracted inside the glass assembly and then exits toward the reflective layer, so that the light exits from the glass assembly in some specific areas. In this way, the glass assembly may further include a light-guiding layer for guiding the light emitted by the light-emitting layer to a desired position. For example, in a glass assembly 200-3 of an embodiment shown in FIG. 6, a light-guiding layer 190 is located in the shielding layer 140 along the cross-sectional direction of the glass body and is arranged on the side of the light-emitting layer 160 facing the shielding layer 140 to receive the light emitted from the light-emitting layer 160 toward the shielding layer 140 and guide the light to the side of the light-emitting layer 160 facing the reflective layer 150.
[0083] As can be seen from FIG. 6, in the cross-sectional direction of the glass assembly 200-3, the light-guiding layer 190 includes a first region 190a corresponding to the light-emitting layer 160. In an embodiment with the light-diffusion layer 180, the light-diffusion layer 180 may be located in the shielding layer 140 along the cross-sectional direction of the glass body and arranged between the light-guiding layer 190 and the reflective layer 150 or formed in the reflective layer 150 for diffusing the light guided by the light-guiding layer 190, and the light-guiding layer 190 may further include a second region 190b corresponding to the light-diffusion layer 180. In some embodiments, the glass assembly 200-3 may further include a picture frame structure arranged around the light-emitting layer 160 and / or the light-diffusion layer 180 and / or the light-guiding layer 190. For example, in the embodiment shown in FIG. 6, a picture frame structure 170b arranged around the light-emitting layer 160 and the light-guiding layer 190 is exemplarily shown (exemplarily shown on the right side of the light-guiding layer 190 in the figure) , and the picture frame structure 170b may be selected as a tinted material, such as tinted PVB. In the same way, a picture frame structure 170d may be arranged around the light-diffusion layer 180 similar to the embodiment shown in FIG. 5 (exemplarily shown on the right side of the light-diffusion layer 180 in the figure) , and the picture frame structure 170d may be selected as a tinted material, such as tinted PVB. In addition, in some embodiments, a light-shielding layer 170c may be arranged on a side of the light-emitting layer 160 facing the reflective layer 150, and the light-shielding layer 170c is located in the shielding layer 140 along the cross-sectional direction of the glass body and arranged between the light-emitting layer 160 and the reflective layer 150, so as to prevent the light emitted by the light-emitting layer 160 from being directly transmitted to the reflective layer 150. Further optionally, the light-shielding layer 170c covers the light-emitting layer 160 along the cross-sectional direction of the glass body. Here, the light-shielding layer 170c may also be selected as a tinted material, for example, tinted enamel or tinted adhesive film, such as tinted PVB film or tinted EVA film. In this embodiment, the adhesive layer 130c located in the shielding layer 140 along the cross-sectional direction of the glass body may also be provided, and the adhesive layer 130c may be tinted PVB or may be configured as transparent PVB. Similarly, when the glass assembly is applied as the front windshield, the adhesive layer corresponding to the visible area of the front windshield may be transparent, that is, in the embodiment shown in FIG. 6, a PVB with segmented tinting may be used.
[0084] According to different requirements, the light-guiding layer may be various types of optical films or optical coatings, such as reflective film or reflective coating (metal or dielectric) applied to a substrate (preferably PET or PVB) or reflective strip (such as aluminium strip) , wherein the reflective film may be a prism film to change the transmission angle or path of the light emitted by the light-emitting layer 160 through reflection and / or refraction.
[0085] In the various embodiments listed above, the light-diffusion layer 180 may be formed between the light-emitting layer 160 or the light-guiding layer 190 and the reflective layer 150 in the form of film or coating. Similarly, "between" herein encompasses various arrangements in which the light-diffusion layer is directly adjacent to or not directly adjacent to the light-emitting layer or the light-guiding layer or the reflective layer. For example, in the embodiment shown in FIG. 3, the light-diffusion layer may be directly adjacent to the light-emitting layer 160, and in the embodiments shown in FIG. 4 to FIG. 6, the light-diffusion layer may be formed on the surface of the second glass body 120 away from the reflective layer 150. In addition, the light-diffusion layer 180 may be advantageously configured to have a neutral color, such as white, or may perform light transmission compensation on the color of the reflective layer 150 to produce a soft and balanced illumination display effect. Optionally, the light-diffusion layer 180 may include polymethyl methacrylate (PMMA) film having a light diffusion structure (for example, combined with polyurethane as a thermoplastic material) and / or polyethylene terephthalate (PET) film having a light diffusion structure and / or diffusion adhesive film and / or polymer dispersed liquid crystal (PDLC) film, and a material of the diffusion adhesive film is the same as a material of the adhesive layer, such as PVB film having neutral color or EVA film having neutral color or PU film having neutral color. Advantageously, the neutral color here may be white. For example, the PMMA having the light diffusion structure and / or the PET having the light diffusion structure and / or the white PVB can be formed on the surface of the second glass body 120 away from the reflective layer 150 by means of film layer as shown in the embodiments shown in FIGS. 4 to 6. Here, "light diffusion structure" means that the film layer has microstructures such as microscopic structures or microscopic textures, etc., and the size can be in micron or even nanometer level, and the light will be scattered or diffused after contacting the microstructures, thereby changing the transmission angle or path of the light and guiding the light out. Optionally, the PDLC film may also be sandwiched between the light-emitting layer 160 and the reflective layer 150 in a non-switching manner. The PDLC film is usually referred to as privacy film or switchable film, and can be switched, for example, between different states with different haze values as required, so that the diffusion function for the light can be realized by using high visible light transmittance and high haze of the PDLC film itself without switching the state. For the form of coating, for example, a material, such as white enamel, etc., may be printed on the surface of the second glass body 120 facing the reflective layer 150 or the surface of the second glass body 120 away from the reflective layer 150 by screen printing or inkjet printing, so as to form the light-diffusion layer in the form of coating. It should be understood that when, for example, a white PVB is used as the light-diffusion layer in the form of film layer, if PVB is used for the remaining portions of the adhesive layer located in the shielding layer along the cross-sectional direction of the glass body, the PVB of these portions may be transparent or tinted and can be fused with the white PVB used as the light-diffusion layer during the lamination process of the glass assembly. Similarly, when the light-diffusion layer 180 adopts an adhesive film made of the same material as the adhesive layer, the light-diffusion layer 180 and the adjacent adhesive layer may be combined with each other to form a single adhesive layer, that is, for example, a partially white and segmented PVB may be adopted.
[0086] In some embodiments, the light-diffusion layer 180 may be configured as a light diffusion structure formed in the first glass body or the second glass body (which may be formed in the second glass body 120 in the illustrated embodiment) between the light-emitting layer or the light-guiding layer and the reflective layer by laser engraving and / or formed in the reflective layer 150 by laser engraving. In a glass assembly 200-4 of an embodiment shown in FIG. 7, the light-diffusion layer 180 composed of the light diffusion structure formed in the reflective layer 150 by laser engraving is exemplarily shown. In a glass assembly 200-5 of an embodiment shown in FIG. 8, the light-diffusion layer 180 composed of the light diffusion structure formed in the second glass body 120 by laser engraving is exemplarily shown.
[0087] In various embodiments of the above examples, the light-emitting layer may include one or more light-emitting diode (LED) strips and / or one or more light-emitting diode matrices and / or a plurality of light-emitting diodes, wherein a plurality of light-emitting diode strips and / or a plurality of light-emitting diode matrices and / or the plurality of light-emitting diodes may be arranged in parallel and / or arranged in a cross way, and each light-emitting diode strip and / or each light-emitting diode matrix may be configured to include a plurality of portions to meet different display requirements.
[0088] A glass assembly 200-2-1 shown in FIG. 9 is similar to the glass assembly 200-2 shown in FIG. 5, wherein the light-emitting layer includes, for example, a plurality of LED strips arranged in parallel, such as a first LED strip 160a, a second LED strip 160b and a third LED strip 160c. The plurality of LED strips may be configured to, for example, have different colours. For example, the light emitted by the plurality of LED strips may be red, green, blue, etc., respectively, to obtain display effects of a plurality of colours, or the light of different colours may be switched and displayed based on different scenes as described above, for example, red light provides warning information, blue light provides communication information, and so on. Alternatively, the plurality of LED strips may be configured, for example, to be the same color, i.e., the plurality of LED strips having single color may be integrated to display a relatively thicker line of light in a more cost effective manner.
[0089] FIG. 10 illustrates an example when the glass assembly is applied to the front windshield. Taking the glass assembly 100 as an example, in the use state, the shielding layer 140 is located at the lower edge of the glass assembly 100, the reflective layer 150 is completely located in the shielding layer 140 along the cross-sectional direction of the glass body, and the light-emitting layer including, for example, the first LED strip 160a, the second LED strip 160b, the third LED strip 160c and the fourth LED strip 160d is arranged along the contour of the reflective layer 150, and presents a mode of being partially arranged in parallel and partially arranged in a cross way. For example, the first LED strip 160a is arranged in a cross way relative to the second LED strip 160b, and the second LED strip 160b is arranged in parallel relative to the third LED strip 160c. In this way, due to the shielding effect of the reflective layer 150, the selectivity of the LED strip can be more diversified for the light-emitting layer. Likewise, the plurality of LED strips may be configured, for example, to have the same or different colours. Certainly, the plurality of LED strips may also be arranged along the contour of the shielding layer 140. The plurality of LED strips arranged along the contour of the shielding layer 140 or the reflective layer 150 can cost-effectively provide longer line of light and can provide more diversified illumination display effects, for example, implementing an illumination display effect of different colours (for example, red-green-blue) displayed sequentially or changed on the longer line of light.
[0090] It should be understood that even if the plurality of LED strips and / or the plurality of LED matrices and / or the plurality of LEDs are used, the light emitted by the light-emitting layer and / or the light-emitting layer is still visually continuous regardless of the arrangement.
[0091] It should be understood that, in the embodiments shown in FIG. 1 to FIG. 9, the number of the adhesive layer between the first glass body 110 and the second glass body 120 is not limited, and additional adhesive layers may be arranged between appropriate laminated structures according to different requirements. In addition, although spaces are shown between the laminated structures arranged along the cross-sectional direction of the glass body in the illustrated embodiments, the laminated structures in the laminated glass assembly are bonded or fused with each other without the spaces. For example, in the embodiment shown in FIG. 5, a transparent PVB may be further added between the light-diffusion layer 180 and the second glass body 120. Similarly, in the embodiment shown in FIG. 6, a transparent PVB may be further added between the light-diffusion layer 180 and the second glass body 120 and between the light-diffusion layer 180 and the light-guiding layer 190. After the glass assembly is laminated, the laminated structures between the first glass body 110 and the second glass body 120 are bonded or fused with each other without the spaces.
[0092] In some embodiments, the glass assembly may further include a functional component arranged between the shielding layer and the reflective layer. The functional component includes, for example, a photoelectric sensor. As an example, the photoelectric sensor may include photoresistor and / or phototransistor, so that the brightness of the ambient illumination that can be provided by the light-emitting layer can be verified to determine and adjust the brightness of the light emitted by the light-emitting layer, or to determine and adjust the brightness of the light emitted by the light-emitting layer when combined with display effect of the pattern and / or the image provided by the reflective layer, thereby ensuring the comfort of the driver and the passenger during observation.
[0093] In some embodiments, the glass assembly includes a control unit, which may include vehicle control unit and / or remote control unit and / or electronic control unit of the light-emitting layer and / or electronic control unit of a display unit that projects a pattern and / or an image to the reflective layer. The control unit may be configured to: acquire an instruction of a display region for displaying a pattern and / or an image through the reflective layer, or determine a display region for displaying a pattern and / or an image through the reflective layer; make a light-emitting region of the light-emitting layer overlapping with the display region not emit light, and / or make a light-emitting region of the light-emitting layer not overlapping with the display region emit light, in response to the display region displaying the pattern and / or the image. In a scene in which a plurality of LED strips or a plurality of LED matrices or a plurality of LEDs are used, when the light-emitting region is controlled to emit the light or not emit the light, the plurality of LED strips or the plurality of LED matrices or the plurality of LEDs may be separately controlled or simultaneously controlled based on different requirements. 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.
[0094] 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 a display region for displaying a pattern and / or an image through the reflective layer and / or control a light-emitting region of the light-emitting layer to emit light or not to emit light. Optionally, the control unit may further comprise vehicle control unit and / or remote control unit and / or electronic control unit of the light-emitting layer and / or electronic control unit of a display unit that projects a pattern and / or an image to the reflective layer.
[0095] 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.
[0096] 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, a change of expression, a change of the human eyes'position, etc. ) , 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) . Advantageously, the control unit may be configured to track a position of human eyes to determine the display region for displaying a pattern and / or an image through the reflective layer. For example, the control unit may be configured to track the position of the human eyes by using a driver monitoring system (for example, a camera) , and manipulate a position and an orientation of a display unit for projecting a pattern and / or an image on a dashboard so that a virtual image presented by using the reflective layer can adapt to the position of the human eyes, so as to determine a display region for displaying a pattern and / or an image through the reflective layer. It should be understood that the above exemplarily 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.
[0097] Regardless of the arrangement and combination manner, the glass assembly of the present disclosure provides the immersive display effect of the pattern and / or the image with enhanced contrast through the combination of the shielding layer and the reflective layer, and provides the display effect of continuous and fixed-position light through the light-emitting layer. The user can alternatively achieve the display effect of the pattern and / or the image or the display effect of the light according to different requirements, or achieve the combination of the two effects, thereby a product with market competitiveness can be obtained cost-effectively.
[0098] It should be understood that the glass assembly of the present disclosure provides the display region for the pattern and / or the image and the light-emitting region for the light, the display region and the light-emitting region may be configured to overlap or not overlap with each other depending on different occasions and requirements. Herein, "overlap" encompasses cases in which the display region and the light-emitting region are completely overlapped and partially overlapped in the orthographic projection region or coverage region in the cross-sectional direction of the glass body. When the display region and the light-emitting region are overlapped, the pattern and / or the image displayed by the reflective layer conflicts with the light emitted by the light-emitting layer, that is, the light emitted by the light-emitting layer might affect the definition of the displayed pattern and / or the image, and vice versa. Therefore, when the display region and the light-emitting region are used at the same time to achieve the combination of the two effects, the light of the light-emitting region should be prevented from interfering with the pattern and / or the image of the display region. In the case where the display region and the light-emitting region are not overlapped with each other, it is possible to achieve a single display effect or a combination of the two effects at the same time, thereby further improving the use atmosphere and visual experience inside the vehicle.
