[0044] Hereinafter, exemplary embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0045] An embodiment of the present invention provides a dimming device, including a dimming component, a display component and a touch component, wherein an electromagnetic shielding component is arranged 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.

[0046] By setting an electromagnetic shielding component between the dimming component and the touch component, the inventors found through experiments that 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) can be effectively improved. This is because the electromagnetic shielding component shields the electromagnetic radiation generated to the outside when a voltage is applied to the electrode layer in the dimming component, thereby preventing the electromagnetic radiation from affecting the touch detection function of the touch component.

[0047] According to the different specific settings of the electromagnetic shielding component and the different relative positions of the dimming component, the display component and the touch component, the dimming device in the present invention has a variety of specific implementations, which are described in detail below.

[0048] Embodiment 1

[0049] Figure 1 The schematic diagram of the dimming device provided in the first embodiment of the present invention is shown. The dimming device 11 comprises a dimming component 111, a touch component 112 and a display component 113 which are stacked. The touch component 112 is located between the dimming component 111 and the display component 113.

[0050] The dimming component 111 can modulate the intensity, color, phase, polarization and / or direction of the incident light. Therefore, as an example, the dimming component 111 can be a component that can adjust the light transmittance, or a component that can adjust its own haze, or a component that can adjust both the light transmittance and its own haze.

[0051] Types of dimming components 111 may include electro-variable dimming devices, liquid crystal dimming devices, and / or SPD dimming devices.

[0052] Among them, electrochromic dimming devices and SPD dimming devices can adjust light transmittance, and liquid crystal dimming devices can adjust light transmittance.

[0053] In addition, there is a liquid crystal dimming device that can adjust both the light transmittance and the haze, such as the liquid crystal dimming device in the Chinese invention patent application 202111232990.8 applied by the applicant in 2021, which will not be repeated here.

[0054] The display component 113 may be a projection display component, specifically a transparent projection display component. As an example, the structure of the display component 113 may adopt the structure of the optical film in Chinese invention patent 201710193830.4, which will not be described in detail here.

[0055] In this embodiment, the modulation of the incident light by the dimming component 111 can not only achieve changes in the energy regulation and visual effects of the entire dimming device, but can 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 the external light can be controlled by the dimming component 111 to adjust the intensity of the incident light on the back side of the display component 113, while not affecting the projection reflection imaging efficiency of the display component 113, thereby improving the display effect of the display component 113.

[0056] The touch control component 112 is used to detect the user's touch control operation. The user's intention of performing the touch control operation may be, for example, to adjust the working state of the dimming component 111 and / or to adjust the working state of the display component 113 .

[0057] An electromagnetic shielding component 114 is disposed 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 .

[0058] The electromagnetic shielding component 114 may be made of a conductive material, such as a metal or a metal oxide. As an example, the electromagnetic shielding component 114 may include an ITO (Indium-Tin-Oxide) layer.

[0059] This embodiment accordingly provides a laminated product, such as Figure 2 As shown, it includes a stacked first substrate 21, a first adhesive layer 22, the dimming device 11, a second adhesive layer 23, and a second substrate 24. 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 among 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, in particular, the third adhesive layer 25 is provided between every two adjacent components in the dimming device 11 as an example for description. The third adhesive layer 25 is used to fix the components adjacent to each other on both sides.

[0060] The first adhesive layer 22, the second adhesive layer 23 and / or the third adhesive layer 25 can be hot melt adhesive. The hot melt adhesive can include thermoplastic material or thermosetting material. The thermoplastic material can include PVB (Polyvinyl Butyral) or SGP (Sentry Glas Plus, ionic intermediate film). The thermosetting material can include: EVA (Ethylene VinylAcetate, ethylene-vinyl acetate copolymer) or POE (Polyolefin Elastomer). POE in a narrow sense is made of metallocene-catalyzed ethylene-alpha olefin copolymer.

[0061] The laminated product in this embodiment can be a laminated glass product in practice. 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 a flat surface or a curved surface. The curved surface can be a single curved surface or a double curved surface.

[0062] Embodiment 2

[0063] Figure 3 1 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 that are stacked. Different from the above-mentioned Embodiment 1, the display component 113 in this embodiment 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 may be the same as the corresponding components in Embodiment 1, and will not be repeated here.

[0064] In this embodiment, the electromagnetic shielding component 114 is located outside the display component 113, but is 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. Of course, the electromagnetic shielding component 114 can also be set at these two positions to enhance the electromagnetic shielding effect. Figure 3 In the example shown, the electromagnetic shielding component 114 is located between the dimming component 111 and the display component 113 .

[0065] This embodiment accordingly provides a laminated product, such as Figure 4As shown, it includes a stacked first substrate 21, a first adhesive layer 22, the dimming device 12, a second adhesive layer 23, and a second substrate 24. A third adhesive layer 25 is provided between at least two adjacent components of the dimming component 111, the electromagnetic shielding component 114, the display component 113, and the touch component 112 in the dimming device 12. In this embodiment, in particular, the third adhesive layer 25 is provided between every two adjacent components in the dimming device 12 as an example for description. The third adhesive layer 25 is used to fix the adjacent components on both sides.

[0066] The laminated product in this embodiment can be a laminated glass product in practice. 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 a flat surface or a curved surface. The curved surface can be a single curved surface or a double curved surface.

[0067] It should be noted that in the above-mentioned Embodiment 1 and Embodiment 2, since the electromagnetic shielding components are arranged outside the display component,

[0068] Embodiment 3

[0069] When the display component is located between the dimming component and the touch control component, the electromagnetic shielding component can be disposed inside the display component in order to reduce the thickness of the entire device and simplify the process. Figure 5 A schematic diagram of a dimming device provided by a third embodiment of the present invention is shown.

[0070] 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 .

[0071] In this embodiment, the electromagnetic shielding component is located inside the display component. Figure 5 A specific structural diagram of the display component 1131 is exemplarily shown in FIG.

[0072] The display assembly 1131 includes a base layer 11311, a projection display layer 11312, and a cover layer 11313. The base layer 11311 has an uneven structured surface on one side facing the projection display layer 11312. The transparent projection layer 11312 is located on the side of the base layer 11311 having the uneven structured surface. In one example, the projection display layer 11312 can be substantially conformal 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.

[0073] The refractive index of the projection display layer 11312 is different from the refractive index of the base layer 11311 and the cover layer 11313, so that an optical surface can be formed at the projection display layer 11312, the reflectivity at this position can be enhanced, and the purpose of transparent display can be achieved. At the same time, when the projection display layer 11312 has an uneven structured surface, the diffuse reflection effect of light can be enhanced, so that projection display can be achieved at the projection display layer 11312, that is, the projection imaging surface is at the projection display layer 11312. Further, the refractive index of the base layer 11311 and the cover layer 11313 can be set to be the same, so that the ambient light from the opposite side of the display component 1131 can pass through the display component 1131 without basically changing the transmission direction, so that the user can clearly see the ambient scene through the display component 1131, and then the image displayed by the projection display layer 11312 "floats" in space to achieve transparent display.

[0074] In this embodiment, the electromagnetic shielding component 1141 is located on one side of the projection display layer 11312, and can be located on any one side of the two sides of the projection display layer 11312. Figure 5 In particular, the electromagnetic shielding component 1141 is located between the projection display layer 11312 and the base layer 11311.

[0075] It should be noted that when the projection display layer 11312 is composed of a multi-layer structure, for example, including a multi-layer dielectric film, the electromagnetic shielding component 1141 can also be arranged inside the projection display layer 11312, for example, between at least two adjacent layer structures in the multi-layer structure of the projection display layer 11312.

[0076] In this embodiment, the manufacturing process of the electromagnetic shielding component 1141 can be made by a film forming process during or after the process of making the projection display layer 11312 of the display component. The electromagnetic shielding component 1141 can be made of a conductive material, so a film forming process of a layer of conductive material can be added during the film forming process of the projection display layer 11312 of the display component to achieve the manufacturing of the electromagnetic shielding component 1141, so the overall process of the existing process is less affected. Moreover, since the electromagnetic shielding component 1141 is integrated in the display component 1131, there is no need to set a substrate in the electromagnetic shielding component 1141, thereby reducing the thickness and cost of the entire device.

[0077] exist Figure 5In the example shown, the base layer 11311 in the display component 1131 is close to one side of the dimming component 111, and the cover layer 11313 is close to one side of the touch component 112. It should be clear to those skilled in the art that in an alternative embodiment, the orientation of the display component 1131 may be reversed, that is, the base layer 11311 is arranged close to the touch component 112, and the cover layer 11312 is arranged close to the dimming component 111.

[0078] In other alternative embodiments, the concepts of the base layer 11311 and the cover layer 11313 may be relative, for example, the cover layer 11313 may be manufactured first, then the projection display layer 11312 and the electromagnetic shielding layer 1141 may be manufactured, and finally the base layer 11311 may be manufactured. Alternatively, the base layer 11311 and the cover layer 11313 may be manufactured separately at the same time, then the projection display layer 11312 and the electromagnetic shielding layer 1141 may be manufactured on one of the base layer 11311 and the cover layer 11313, and then the other of the base layer 11311 and the cover layer 11313 may be fixed to the side of the projection display layer 11312 or the electromagnetic shielding layer 1141 facing away from the base layer 11311.

[0079] It should be noted that, in some examples, the covering layer 11313 in the display component 1131 may be omitted.

[0080] This embodiment accordingly provides a laminated product, such as Figure 6 As shown, it includes a stacked first substrate 21, a first adhesive layer 22, the dimming device 13, a second adhesive layer 23, and a second substrate 24. 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, in particular, the third adhesive layer 25 is provided between every two adjacent components in the dimming device 11 as an example for description. The third adhesive layer 25 is used to fix the components adjacent to each other on both sides.

[0081] The first adhesive layer 22, the second adhesive layer 23 and / or the third adhesive layer 25 can be hot melt adhesive. The hot melt adhesive can include thermoplastic material or thermosetting material. The thermoplastic material can include PVB (Polyvinyl Butyral) or SGP (Sentry Glas Plus, ionic intermediate film). The thermosetting material can include: EVA (Ethylene VinylAcetate, ethylene-vinyl acetate copolymer) or POE (Polyolefin Elastomer). POE in a narrow sense is made of metallocene-catalyzed ethylene-alpha olefin copolymer.

[0082] The laminated product in this embodiment can be a laminated glass product in practice. 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 a flat surface or a curved surface. The curved surface can be a single curved surface or a double curved surface.

[0083] Embodiment 4

[0084] The projection display layer in the display assembly in the third embodiment above achieves diffuse reflection effect through an uneven structured surface, so the projection display imaging surface of the display assembly forms a "real image" at the position of the projection display layer.

[0085] In practice, for example, in HUD (Head-Up Display) and other scenes, the projection display imaging result needs to be a virtual image, and the virtual image position can be set to a comfortable viewing distance. In response to such requirements, the projection display layer in the display component in the embodiment of the present invention needs to be set to have an overall mirror reflection effect. For example Figure 7 A schematic diagram of a dimming device provided in the fourth embodiment is shown.

[0086] 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 .

[0087] The display component 1132 includes a base layer 11321, a projection display layer 11322, and a cover layer 11323. Different from the projection display layer in the third embodiment, 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 a plane. The refractive index of the projection display layer 11322 is different from the refractive index of the base layer 11321 and the cover layer 11323, so that an optical surface can be formed at the position of the projection display layer 11322, thereby enhancing the reflectivity at this position and achieving the purpose of transparent display. When the image light is incident on the projection display layer 11322 in the display component 1132 from one side of the touch component 112, the incident light exhibits a mirror reflection effect, thereby realizing a plane mirror reflection function through the projection display layer 11322, and obtaining a virtual image located in the space on the side of the projection display layer 11322 facing the dimming component 111. Furthermore, the refractive indices of the base layer 11321 and the covering layer 11323 can be set to be the same, so that the ambient light from the opposite side of the display component 1132 can pass through the display component 1132 without basically changing the transmission direction, so that the user can clearly see the environmental scene through the display component 1132, and then the image displayed by the projection display layer 11322 "floats" in the space to achieve transparent display, and the floating image is usually not at the location of the projection display layer 11322.

[0088] In this embodiment, the electromagnetic shielding component 1142 is located on one side of the projection display layer 11322, and can be located on any one side of the two sides of the projection display layer 11322. Figure 7 In particular, the electromagnetic shielding component 1142 is located between the projection display layer 11322 and the covering layer 11323.

[0089] It should be noted that when the projection display layer 11322 is composed of a multi-layer structure, for example, including a multi-layer dielectric film, the electromagnetic shielding component 1142 can also be arranged inside the projection display layer 11322, for example, between at least two adjacent layer structures in the multi-layer structure of the projection display layer 11322.

[0090] exist Figure 7 In the example shown, the base layer 11321 in the display component 1132 is close to one side of the dimming component 111, and the cover layer 11323 is close to one side of the touch component 112. It should be clear to those skilled in the art that in an alternative embodiment, the orientation of the display component 1132 can also be reversed, that is, the base layer 11321 is set close to the touch component 112, and the cover layer 11322 is close to the dimming component 111.

[0091] In other alternative embodiments, the concepts of the base layer 11321 and the cover layer 11323 may be relative, for example, the cover layer 11323 may be manufactured first, then the projection display layer 11322 and the electromagnetic shielding layer 1142 may be manufactured, and finally the base layer 11321 may be manufactured. Alternatively, the base layer 11321 and the cover layer 11323 may be manufactured separately at the same time, then the projection display layer 11322 and the electromagnetic shielding layer 1142 may be manufactured on one of the base layer 11321 and the cover layer 11323, and then the other of the base layer 11321 and the cover layer 11323 may be fixed to the side of the projection display layer 11322 or the electromagnetic shielding layer 1142 facing away from the base layer 11321.

[0092] It should be noted that, in some examples, the covering layer 11323 in the display component 1132 may be omitted.

[0093] This embodiment accordingly provides a laminated product, such as Figure 8 As shown, it includes a stacked first substrate 21, a first adhesive layer 22, the dimming device 14, a second adhesive layer 23, and a second substrate 24. 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, the third adhesive layer 25 is provided between every two adjacent components in the dimming device 14 as an example for description. The third adhesive layer 25 is used to fix the components adjacent to each other on both sides.

[0094] The first adhesive layer 22, the second adhesive layer 23 and / or the third adhesive layer 25 can be hot melt adhesive. The hot melt adhesive can include thermoplastic material or thermosetting material. The thermoplastic material can include PVB (Polyvinyl Butyral) or SGP (Sentry Glas Plus, ionic intermediate film). The thermosetting material can include: EVA (Ethylene VinylAcetate, ethylene-vinyl acetate copolymer) or POE (Polyolefin Elastomer). POE in a narrow sense is made of metallocene-catalyzed ethylene-alpha olefin copolymer.

[0095] The laminated product in this embodiment can be a laminated glass product in practice. 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 a flat surface or a curved surface. The curved surface can be a single curved surface or a double curved surface.

[0096] Embodiment 5

[0097] The surface of the projection display layer in the display assembly in the fourth embodiment is a plane, so the size and position of the virtual image formed by the display assembly conform to the law of plane mirror imaging, which cannot meet certain design requirements (such as enlarging the size of the virtual image or pushing the virtual image position away). In order to meet these more flexible requirements, the projection display layer in the display assembly needs to provide the imaging function of a curved reflector. For example, Fig. 9 A schematic diagram of a dimming device provided in Embodiment 5 of the present invention is shown, wherein the projection display layer of the dimming device provides the function of a concave reflector.

[0098] like Fig. 9 As shown, 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 .

[0099] The display component 1133 includes a base layer 11331, a projection display layer 11332, and a cover layer 11333. The projection display layer 11332 in this embodiment has a substantially smooth surface, and as an example, the surface of the projection display layer 11332 facing the touch control component 112 in this embodiment is a concave surface.

[0100] The refractive index of the projection display layer 11332 is different from the refractive index of the base layer 11331 and the cover layer 11333, so that an optical surface can be formed at the projection display layer 11332 position, the reflectivity at this position is enhanced, and the purpose of transparent display is achieved. When the image light is incident on the projection display layer 11332 in the display component 1133 from one side of the touch component 112, the incident light presents a concave mirror reflection effect, so that the concave mirror reflection function is realized through the projection display layer 11332, and a virtual image is obtained 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, etc.) of the concave surface of the projection display layer 11322 to meet the user's imaging requirements for the entire system.

[0101] Furthermore, the refractive indices of the base layer 11331 and the covering layer 11333 can be set to be the same, so that the ambient light from the opposite side of the display component 1133 can pass through the display component 1133 without basically changing the transmission direction, so that the user can clearly see the environmental scene through the display component 1132, and then the image displayed by the projection display layer 11332 "floats" in the space to achieve transparent display, and the floating image is usually not at the location of the projection display layer 11332.

[0102] In this embodiment, the electromagnetic shielding component 1143 is located in the projection display layer 11332. Specifically, the projection display layer 11332 includes a multilayer structure and can be divided into two parts, which can be respectively referred to as the first part 11332a and the second part 11332b of the projection display layer. The electromagnetic shielding component 1143 is arranged between the first part 11332a and the second part 11332b of the projection display layer. Therefore, in this example, the electromagnetic shielding component 1143 is arranged inside the projection display layer 11332.

[0103] In other alternative embodiments, the concepts of the base layer 11331 and the cover layer 11333 may be relative, for example, the cover layer 11333 may be manufactured first, then the projection display layer 11332 and the electromagnetic shielding layer 1143 may be manufactured, and finally the base layer 11331 may be manufactured. Alternatively, the base layer 11331 and the cover layer 11333 may be manufactured separately at the same time, then the projection display layer 11332 and the electromagnetic shielding layer 1143 may be manufactured on one of the base layer 11331 and the cover layer 11333, and then the other of the base layer 11331 and the cover layer 11333 may be fixed to the side of the projection display layer 11332 facing away from the base layer 11331.

[0104] It should be noted that, in some examples, the covering layer 11333 in the display component 1133 may be omitted.

[0105] This embodiment accordingly provides a laminated product, such as Fig.10 As shown, it includes a stacked first substrate 21, a first adhesive layer 22, the dimming device 15, a second adhesive layer 23, and a second substrate 24. 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 among the dimming component 111, the touch component 112, and the display component 1133 in the dimming device 15. In this embodiment, in particular, the third adhesive layer 25 is provided between every two adjacent components in the dimming device 15 as an example for description. The third adhesive layer 25 is used to fix the components adjacent to each other on both sides.

[0106] The first adhesive layer 22, the second adhesive layer 23 and / or the third adhesive layer 25 can be hot melt adhesive. The hot melt adhesive can include thermoplastic material or thermosetting material. The thermoplastic material can include PVB (Polyvinyl Butyral) or SGP (Sentry Glas Plus, ionic intermediate film). The thermosetting material can include: EVA (Ethylene VinylAcetate, ethylene-vinyl acetate copolymer) or POE (Polyolefin Elastomer). POE in a narrow sense is made of metallocene-catalyzed ethylene-alpha olefin copolymer.

[0107] The laminated product in this embodiment can be a laminated glass product in practice. 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 a flat surface or a curved surface. The curved surface can be a single curved surface or a double curved surface.

[0108] It should be noted that when the projection display layer in the display assembly in the above embodiments has a conductive material layer that improves reflectivity, the conductive material layer itself can also serve as an electromagnetic shielding component.

[0109] In addition, the area where the conductive material in the electromagnetic shielding assembly in each of the above embodiments is located can be in the entire surface, or can be arranged in a grid shape or a strip shape according to the design.

[0110] In addition, in order to further improve the electromagnetic shielding performance of the electromagnetic shielding component and minimize the influence of the dimming component on the touch control component, in a preferred embodiment, the electromagnetic shielding component can be grounded.
