[0003] Laminated smart glass is a product in which a dimming device (such as a flexible dimming film device) is bonded between two panes of glass. This dimming device allows for the adjustment of transmittance; examples include EC-type and dye-liquid crystal dimming devices. Other types of dimming devices include those that can adjust haze, such as PDLC-type dimming devices. Dimming devices, and laminated smart glass incorporating them, are widely used in architectural and automotive doors and windows, interior partitions, and aircraft ventilation systems.

[0004] There is a market demand for laminated smart glass used in automotive doors and windows to enhance touch interaction and transparent display functions. This necessitates the development of multifunctional glass products that integrate dimming, touch, and transparent display devices. Chinese utility model patent CN221660281U proposes a composite glass with projection, dimming, and touch functions. However, after testing, the inventors discovered that applying an electric field to the dimming device affects the touch device's detection function, thus reducing touch sensitivity.

Embodiments of this application may be performed independently of each other, or may be performed together in an interdependent relationship.

[0045] Hereinafter, exemplary embodiments of this application will be described in detail with reference to the accompanying drawings.

[0046] This invention provides a dimming device, including a dimming component, a display component, and a touch component, wherein an electromagnetic shielding component is disposed between the dimming component and the touch component, and the electromagnetic shielding layer is used to reduce signal interference between the dimming component and the touch component.

[0047] By placing an electromagnetic shielding component between the dimming component and the touch component, the inventors discovered through experiments that they could effectively improve the problem of decreased sensitivity of the touch detection function of the touch component when the dimming component is working (especially when a strong electric field is applied). This is because the electromagnetic shielding component shields the electromagnetic radiation generated by the electrode layer in the dimming component when a voltage is applied, thereby preventing the electromagnetic radiation from affecting the touch detection function of the touch component.

[0048] Depending on the specific location of the electromagnetic shielding component and the different relative positions of the dimming component, display component, and touch component, the dimming device of the present invention has various specific implementations, which are described in detail below.

[0049] Example 1

[0050] Figure 1 shows a schematic diagram of a dimming device provided in Embodiment 1 of the present invention. The dimming device 11 includes a dimming component 111, a touch component 112, and a display component 113 stacked together. The touch component 112 is located between the dimming component 111 and the display component 113.

[0051] The dimming component 111 can modulate the intensity, color, phase, polarization, and / or direction of the incident light. Therefore, by way of example, the dimming component 111 can be a component capable of adjusting light transmittance, or a component capable of adjusting its own haze, or a component capable of adjusting both light transmittance and its own haze.

[0052] The dimming component 111 may include electrochromic dimming devices, liquid crystal dimming devices, and / or SPD dimming devices.

[0053] Electrochromic dimming devices and SPD dimming devices can adjust light transmittance, while liquid crystal dimming devices can adjust light transmittance.

[0054] In addition, there is another type of liquid crystal dimming device that can adjust both light transmittance and haze, such as the liquid crystal dimming device in Chinese invention patent application 202111232990.8 filed by the applicant in 2021, which will not be described in detail here.

[0055] Display component 113 can be a projection display component, specifically a transparent projection display component. As an example, the structure of display component 113 can adopt the structure used in the optical film of Chinese Invention Patent 201710193830.4, which will not be described in detail here.

[0056] In this embodiment, the modulation of incident light by the dimming component 111 can not only achieve changes in energy regulation and visual effect of the entire dimming device, but also be used to adjust the background brightness of the display component 113. For example, when the dimming component 111 is located on the back side of the display component 113, the transmittance of external light can be controlled by the dimming component 111 to adjust the intensity of incident light on the back side of the display component 113, without affecting the projection reflection imaging efficiency of the display component 113, thereby improving the display effect of the display component 113.

[0057] The touch component 112 is used to detect the user's touch operation. The user's intention in performing the touch operation may be, for example, to adjust the operating state of the dimming component 111 and / or to adjust the operating state of the display component 113.

[0058] An electromagnetic shielding component 114 is provided between the dimming component 111 and the touch component 112. The electromagnetic shielding component 114 is used to reduce signal interference between the dimming component 111 and the touch component 112.

[0059] The electromagnetic shielding assembly 114 may be made of a conductive material, such as a metal or metal oxide. As an example, the electromagnetic shielding assembly 114 may include an ITO (Indium-Tin-Oxide) layer.

[0060] This embodiment provides a laminated product, as shown in FIG2, including a first substrate 21, a first adhesive layer 22, the aforementioned dimming device 11, a second adhesive layer 23, and a second substrate 24 stacked together. The first adhesive layer 22 and the second adhesive layer 23 are used to fix the dimming device to the first substrate 21 and the second substrate 24, respectively. A third adhesive layer 25 is provided between at least two adjacent components of the dimming component 111, the electromagnetic shielding component 114, the touch component 112, and the display component 113 in the dimming device 11. In this embodiment, specifically, it is described by way of providing a third adhesive layer 25 between every two adjacent components in the dimming device 11. The third adhesive layer 25 is used to fix the components adjacent to each other on both sides.

[0061] The first adhesive layer 22, the second adhesive layer 23, and / or the third adhesive layer 25 can be hot melt adhesives. Hot melt adhesives can include thermoplastic materials or thermosetting materials. Thermoplastic materials can include PVB (Polyvinyl Butyral) or SGP (Sentry Glas Plus). Thermosetting materials can include EVA (Ethylene Vinyl Acetate) or POE (Polyolefin Elastomer). In a narrow sense, POE is made from metallocene-catalyzed ethylene-α-olefin copolymers.

[0062] The laminated product in this embodiment can actually be a laminated glass product. Accordingly, the first substrate 21 and the second substrate 24 can be glass substrates. At least one of the first substrate 21 and the second substrate 24 can be planar or curved. The curved surface can be a single-curved surface or a hyperboloid.

[0063] Example 2

[0064] Figure 3 shows a schematic diagram of a dimming device provided in Embodiment 2 of the present invention. The dimming device 12 includes a dimming component 111, a touch component 112, and a display component 113 stacked together. Unlike Embodiment 1 described above, in this embodiment, the display component 113 is located between the dimming component 111 and the touch component 112. The specific structures of the dimming component 111, the touch component 112, and the display component 113 can be the same as the corresponding components in Embodiment 1, and will not be described again here.

[0065] In this embodiment, the electromagnetic shielding component 114 is located outside the display component 113, but still between the dimming component 111 and the touch component 112. Therefore, the electromagnetic shielding component 114 can be located between the dimming component 111 and the display component 113, or between the display component 113 and the touch component 112. Alternatively, the electromagnetic shielding component 114 can be located at both locations to enhance the electromagnetic shielding effect. In the example shown in FIG3, the electromagnetic shielding component 114 is located between the dimming component 111 and the display component 113.

[0066] This embodiment provides a laminated product, as shown in FIG4, comprising a first substrate 21, a first adhesive layer 22, the aforementioned dimming device 12, a second adhesive layer 23, and a second substrate 24 stacked together. A third adhesive layer 25 is disposed between at least two adjacent components of the dimming component 111, electromagnetic shielding component 114, display component 113, and touch component 112 in the dimming device 12. In this embodiment, specifically, it is described as follows: a third adhesive layer 25 is disposed between every two adjacent components in the dimming device 12. The third adhesive layer 25 is used to fix the components adjacent to each other on both sides.

[0067] The laminated product in this embodiment can actually be a laminated glass product. Accordingly, the first substrate 21 and the second substrate 24 can be glass substrates. At least one of the first substrate 21 and the second substrate 24 can be planar or curved. The curved surface can be a single-curved surface or a hyperboloid.

[0068] It should be noted that in Embodiments 1 and 2 above, since the electromagnetic shielding components are both located outside the display components,

[0069] Example 3

[0070] When the display component is located between the dimming component and the touch component, the electromagnetic shielding component can be placed inside the display component to reduce the overall thickness of the device and simplify the manufacturing process. Figure 5 shows a schematic diagram of a dimming device provided in the third embodiment of the present invention.

[0071] The dimming device 13 includes a dimming component 111, a touch component 112, and a display component 1131. The display component 1131 is located between the dimming component 111 and the touch component 112.

[0072] In this embodiment, the electromagnetic shielding component is located inside the display component, and therefore, FIG5 shows an exemplary schematic diagram of a specific structure of the display component 1131.

[0073] The display assembly 1131 includes a base layer 11311, a projection display layer 11312, and a cover layer 11313. The side of the base layer 11311 facing the projection display layer 11312 has an uneven, structured surface. The transparent projection layer 11312 is located on the side of the base layer 11311 with the uneven, structured surface. In one example, the projection display layer 11312 may substantially conform to the uneven, structured surface of the base layer 11311. The cover layer 11311 is located on the side of the projection display layer 11312 away from the base layer 11311.

[0074] The refractive index of the projection display layer 11312 differs from that of the base layer 11311 and the cover layer 11313, thus forming an optical surface at the location of the projection display layer 11312, enhancing the reflectivity at that location, and achieving transparent display. Simultaneously, when the projection display layer 11312 has an uneven, structured surface, it enhances the diffuse reflection effect of light, thereby enabling projection display at the location of the projection display layer 11312, i.e., the projection imaging surface is located at the location of the projection display layer 11312. Furthermore, the refractive indices of the base layer 11311 and the cover layer 11313 can be set to be the same. This allows ambient light from the opposite side of the display component 1131 to pass through the display component 1131 with minimal change in transmission direction, enabling users to clearly see the surrounding environment through the display component 1131. Consequently, the image displayed through the projection display layer 11312 appears to "float" in space, achieving transparent display.

[0075] In this embodiment, the electromagnetic shielding component 1141 is located on one side of the projection display layer 11312, specifically on either side of the projection display layer 11312. In Figure 5, the electromagnetic shielding component 1141 is specifically located between the projection display layer 11312 and the base layer 11311.

[0076] It should be noted that when the projection display layer 11312 is composed of a multi-layer structure, such as including a multi-layer dielectric film, the electromagnetic shielding component 1141 can also be disposed inside the projection display layer 11312, for example, between at least two adjacent layers in the multi-layer structure of the projection display layer 11312.

[0077] In this embodiment, the electromagnetic shielding component 1141 can be manufactured through a film-forming process during or after the fabrication of the projection display layer 11312 of the display component. Since the electromagnetic shielding component 1141 can be made of conductive material, a film-forming process for a conductive material can be added during the film-forming process of the projection display layer 11312 of the display component to manufacture the electromagnetic shielding component 1141, thus having minimal impact on the overall existing process. Furthermore, because the electromagnetic shielding component 1141 is integrated into the display component 1131, there is no need to additionally place a substrate within the electromagnetic shielding component 1141, thereby reducing the overall thickness and cost of the device.

[0078] In the example shown in Figure 5, the base layer 11311 of the display component 1131 is located closer to the dimming component 111, while the cover layer 11313 is located closer to the touch component 112. Those skilled in the art will understand that in alternative embodiments, the orientation of the display component 1131 can be reversed, with the base layer 11311 positioned closer to the touch component 112 and the cover layer 11312 positioned closer to the dimming component 111.

[0079] In other alternative embodiments, the concepts of base layer 11311 and cover layer 11313 can be relative. For example, the cover layer 11313 can be manufactured first, followed by the projection display layer 11312 and the electromagnetic shielding layer 1141, and finally the base layer 11311. Alternatively, the base layer 11311 and the cover layer 11313 can be manufactured simultaneously, and then the projection display layer 11312 and the electromagnetic shielding layer 1141 can be manufactured on one of the base layer 11311 and the cover layer 11313. Then, the other layer of the base layer 11311 and the cover layer 11313 can be fixed to the side of the projection display layer 11312 or the electromagnetic shielding layer 1141 that faces away from the base layer 11311.

[0080] It should be noted that in some examples, the overlay 11313 in the display component 1131 can be omitted.

[0081] This embodiment provides a laminated product, as shown in FIG6, including a first substrate 21, a first adhesive layer 22, the aforementioned dimming device 13, a second adhesive layer 23, and a second substrate 24 stacked together. The first adhesive layer 22 and the second adhesive layer 23 are used to fix the dimming device 13 to the first substrate 21 and the second substrate 24, respectively. A third adhesive layer 25 is provided between at least two adjacent components of the dimming component 111, the electromagnetic shielding component 1141, the touch component 112, and the display component 1131 in the dimming device 13. In this embodiment, specifically, it is described by way of providing a third adhesive layer 25 between every two adjacent components in the dimming device 11. The third adhesive layer 25 is used to fix the components adjacent to each other on both sides.

[0082] The first adhesive layer 22, the second adhesive layer 23, and / or the third adhesive layer 25 can be hot melt adhesives. Hot melt adhesives can include thermoplastic materials or thermosetting materials. Thermoplastic materials can include PVB (Polyvinyl Butyral) or SGP (Sentry Glas Plus). Thermosetting materials can include EVA (Ethylene Vinyl Acetate) or POE (Polyolefin Elastomer). In a narrow sense, POE is made from metallocene-catalyzed ethylene-α-olefin copolymers.

[0083] The laminated product in this embodiment can actually be a laminated glass product. Accordingly, the first substrate 21 and the second substrate 24 can be glass substrates. At least one of the first substrate 21 and the second substrate 24 can be planar or curved. The curved surface can be a single-curved surface or a hyperboloid.

[0084] Example 4

[0085] In the above embodiment three, the projection display layer in the display component achieves the effect of diffuse reflection through an uneven structured surface. Therefore, the projection display imaging surface of the display component forms a "real image" at the location of the projection display layer.

[0086] In practical applications, such as HUD (Head-Up Display) scenarios, the projected image needs to be a virtual image, and the virtual image's position can be set at a comfortable viewing distance. To address this need, the projection display layer in the display component of this embodiment needs to be configured to have an overall specular reflection effect. For example, Figure 7 shows a schematic diagram of a dimming device provided in Embodiment 4.

[0087] The dimming device 14 includes a dimming component 111, a touch component 112, and a display component 1132. The display component 1132 is located between the dimming component 111 and the touch component 112.

[0088] The display component 1132 includes a base layer 11321, a projection display layer 11322, and a cover layer 11323. Unlike the projection display layer in Embodiment 3, the projection display layer 11322 in this embodiment has a substantially smooth surface, and as an example, the surface of the projection display layer 11322 in this embodiment is planar. The refractive index of the projection display layer 11322 is different from that of the base layer 11321 and the cover layer 11323, thereby forming an optical surface at the location of the projection display layer 11322, enhancing the reflectivity at that location, and achieving the purpose of transparent display. When image light is incident from one side of the touch component 112 onto the projection display layer 11322 in the display component 1132, the incident light exhibits a specular reflection effect, thereby achieving planar specular reflection through the projection display layer 11322, obtaining a virtual image located in the space of the projection display layer 11322 facing the dimming component 111. Furthermore, the refractive indices of the base layer 11321 and the cover layer 11323 can be set to be the same. In this way, ambient light from the opposite side of the display component 1132 can pass through the display component 1132 with basically no change in transmission direction, allowing users to clearly see the ambient scene through the display component 1132. The image displayed by the projection display layer 11322 "floates" in space to achieve transparent display, and the floating image is usually not located at the location of the projection display layer 11322.

[0089] In this embodiment, the electromagnetic shielding component 1142 is located on one side of the projection display layer 11322, specifically on either side of the projection display layer 11322. In Figure 7, the electromagnetic shielding component 1142 is specifically located between the projection display layer 11322 and the cover layer 11323.

[0090] It should be noted that when the projection display layer 11322 is composed of a multi-layer structure, such as including a multi-layer dielectric film, the electromagnetic shielding component 1142 can also be disposed inside the projection display layer 11322, for example, between at least two adjacent layers in the multi-layer structure of the projection display layer 11322.

[0091] In the example shown in Figure 7, the base layer 11321 of the display component 1132 is closer to the dimming component 111, while the cover layer 11323 is closer to the touch component 112. Those skilled in the art will understand that in alternative embodiments, the orientation of the display component 1132 can be reversed, with the base layer 11321 positioned closer to the touch component 112 and the cover layer 11322 closer to the dimming component 111.

[0092] In other alternative embodiments, the concepts of base layer 11321 and cover layer 11323 can be relative. For example, the cover layer 11323 can be manufactured first, followed by the projection display layer 11322 and the electromagnetic shielding layer 1142, and finally the base layer 11321. Alternatively, the base layer 11321 and the cover layer 11323 can be manufactured simultaneously, and then the projection display layer 11322 and the electromagnetic shielding layer 1142 can be manufactured on one of the base layer 11321 and the cover layer 11323. Then, the other layer of the base layer 11321 and the cover layer 11323 can be fixed to the side of the projection display layer 11322 or the electromagnetic shielding layer 1142 that faces away from the base layer 11321.

[0093] It should be noted that in some examples, the overlay 11323 in the display component 1132 can be omitted.

[0094] This embodiment provides a laminated product, as shown in FIG8, including a first substrate 21, a first adhesive layer 22, the aforementioned dimming device 14, a second adhesive layer 23, and a second substrate 24 stacked together. The first adhesive layer 22 and the second adhesive layer 23 are used to fix the dimming device 14 to the first substrate 21 and the second substrate 24, respectively. A third adhesive layer 25 is provided between at least two adjacent components of the dimming component 111, the electromagnetic shielding component 1142, the touch component 112, and the display component 1132 in the dimming device 14. In this embodiment, in particular, it is described by way of providing a third adhesive layer 25 between every two adjacent components in the dimming device 14. The third adhesive layer 25 is used to fix the components adjacent to each other on both sides.

[0095] The first adhesive layer 22, the second adhesive layer 23, and / or the third adhesive layer 25 can be hot melt adhesives. Hot melt adhesives can include thermoplastic materials or thermosetting materials. Thermoplastic materials can include PVB (Polyvinyl Butyral) or SGP (Sentry Glas Plus). Thermosetting materials can include EVA (Ethylene Vinyl Acetate) or POE (Polyolefin Elastomer). In a narrow sense, POE is made from metallocene-catalyzed ethylene-α-olefin copolymers.

[0096] The laminated product in this embodiment can actually be a laminated glass product. Accordingly, the first substrate 21 and the second substrate 24 can be glass substrates. At least one of the first substrate 21 and the second substrate 24 can be planar or curved. The curved surface can be a single-curved surface or a hyperboloid.

[0097] Example 5

[0098] In Embodiment 4, the surface of the projection display layer in the display component is planar. Therefore, the size and position of the virtual image formed by this display component conform to the laws of plane mirror imaging. This cannot meet certain design requirements (such as magnifying the size of the virtual image or pushing the position of the virtual image away). To meet these more flexible requirements, the projection display layer in the display component needs to provide the imaging function of a curved reflector. For example, Figure 9 shows a schematic diagram of the dimming device provided in Embodiment 5 of the present invention. The projection display layer of this dimming device provides the function of a concave reflector.

[0099] As shown in Figure 9, the dimming device 15 includes a dimming component 111, a touch component 112, and a display component 1133. The display component 1133 is located between the dimming component 111 and the touch component 112.

[0100] The display component 1133 includes a base layer 11331, a projection display layer 11332, and a cover layer 11333. In this embodiment, the projection display layer 11332 has a generally smooth surface, and as an example, the surface of the projection display layer 11332 facing the touch component 112 in this embodiment is concave.

[0101] The refractive index of the projection display layer 11332 differs from that of the base layer 11331 and the cover layer 11333, thus allowing the formation of an optical surface at the location of the projection display layer 11332, enhancing the reflectivity at that location and achieving transparent display. When image light is incident from one side of the touch component 112 onto the projection display layer 11332 in the display component 1133, the incident light exhibits a concave specular reflection effect, thereby achieving concave specular reflection through the projection display layer 11332, resulting in a virtual image located in the space on the side of the projection display layer 11332 facing the dimming component 111. The size and imaging position of the virtual image can be adjusted by the shape characteristics (such as curvature) of the concave surface of the projection display layer 11332 to meet the user's imaging needs for the entire system.

[0102] Furthermore, the refractive indices of the base layer 11331 and the cover layer 11333 can be set to be the same. In this way, ambient light from the opposite side of the display component 1133 can pass through the display component 1133 with basically no change in transmission direction, allowing users to clearly see the ambient scene through the display component 1132. The image displayed by the projection display layer 11332 "floates" in space to achieve transparent display, and the floating image is usually not located at the location of the projection display layer 11332.

[0103] In this embodiment, the electromagnetic shielding component 1143 is located within the projection display layer 11332. Specifically, the projection display layer 11332 includes a multi-layer structure and can be divided into two parts, which can be referred to as the first part 11332a and the second part 11332b of the projection display layer, respectively. The electromagnetic shielding component 1143 is disposed between the first part 11332a and the second part 11332b of the projection display layer. Thus, in this example, the electromagnetic shielding component 1143 is disposed inside the projection display layer 11332.

[0104] In other alternative embodiments, the concepts of base layer 11331 and cover layer 11333 can be relative. For example, the cover layer 11333 can be manufactured first, followed by the projection display layer 11332 and the electromagnetic shielding layer 1143, and finally the base layer 11331. Alternatively, the base layer 11331 and the cover layer 11333 can be manufactured simultaneously, and then the projection display layer 11332 and the electromagnetic shielding layer 1143 can be manufactured on one of the base layer 11331 and the cover layer 11333. Then, the other layer of the base layer 11331 and the cover layer 11333 can be fixed to the side of the projection display layer 11332 facing away from the base layer 11331.

[0105] It should be noted that in some examples, the overlay 11333 in the display component 1133 can be omitted.

[0106] This embodiment provides a laminated product, as shown in FIG10, including a first substrate 21, a first adhesive layer 22, the aforementioned dimming device 15, a second adhesive layer 23, and a second substrate 24 stacked together. The first adhesive layer 22 and the second adhesive layer 23 are used to fix the dimming device 15 to the first substrate 21 and the second substrate 24, respectively. A third adhesive layer 25 is provided between at least two adjacent components of the dimming component 111, the touch component 112, and the display component 1133 in the dimming device 15. In this embodiment, in particular, it is described by way of providing a third adhesive layer 25 between every two adjacent components in the dimming device 15. The third adhesive layer 25 is used to fix the components adjacent to each other on both sides.

[0107] The first adhesive layer 22, the second adhesive layer 23, and / or the third adhesive layer 25 can be hot melt adhesives. Hot melt adhesives can include thermoplastic materials or thermosetting materials. Thermoplastic materials can include PVB (Polyvinyl Butyral) or SGP (Sentry Glas Plus). Thermosetting materials can include EVA (Ethylene Vinyl Acetate) or POE (Polyolefin Elastomer). In a narrow sense, POE is made from metallocene-catalyzed ethylene-α-olefin copolymers.

[0108] The laminated product in this embodiment can actually be a laminated glass product. Accordingly, the first substrate 21 and the second substrate 24 can be glass substrates. At least one of the first substrate 21 and the second substrate 24 can be planar or curved. The curved surface can be a single-curved surface or a hyperboloid.

[0109] It should be noted that when the projection display layer in the display component of the above embodiments has a conductive material layer that improves reflectivity, the conductive material layer itself can also act as an electromagnetic shielding component. Therefore, in this case, the projection display layer...

[0110] In addition, the area where the conductive material is located in the electromagnetic shielding assembly in the above embodiments can be a whole surface, or it can be arranged in a grid or strip shape according to the design.

[0111] In addition, in order to further improve the electromagnetic shielding performance of the electromagnetic shielding component and minimize the impact of the dimming component on the touch component, in a preferred embodiment, the electromagnetic shielding component can be grounded.

However, this application is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this application, various simple modifications can be made to the technical solution of this application, and these simple modifications all fall within the protection scope of this application.

[0113] Furthermore, various different implementations of this application can be combined in any way, as long as they do not violate the spirit of this application, they should also be regarded as the content disclosed in this application.
