Description

Technical Field

[0001] This utility model relates to the field of dimming glass technology, and in particular to a dimming glass based on a fully laminated dimming film. Background Technology

[0002] Currently, existing dimming film glass products mainly use glass lamination solutions including EVA, TPU, or PVB. However, the glass lamination process for dimming film glass products requires specific temperature and pressure ranges, and the laminated products need to be in a vacuum-sealed space with appropriate operating time and conditions for glass lamination.

[0003] Among them, the laminating material is highly sensitive to temperature, pressure and time. The lamination process is prone to defects such as bubbles, foreign objects, misalignment, poor adhesive layer, delamination of the dimming film and adhesive overflow, resulting in a low yield of dimming film glass products. In addition, dimming film glass products are highly sensitive to water and oxygen and are exposed to sunlight for a long time, which reduces the stability and service life of dimming film glass products. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a dimming glass based on a fully laminated dimming film to overcome at least one of the above-mentioned defects.

[0005] This application provides a dimming glass based on a fully laminated dimming film, the dimming glass comprising a fully laminated dimming film assembly, a first glass layer, a second glass layer, a spacer assembly, and a screen assembly:

[0007] The fully laminated dimming film assembly includes a dimming film, a barrier film, an optical adhesive, and a sealant; wherein the dimming film and the barrier film are bonded together by the optical adhesive, and the sealant is used to seal the edges of the dimming film, the optical adhesive, and the barrier film.

[0008] Furthermore, the dimming glass is used in outdoor scenarios.

[0009] Furthermore, the dimming glass is also used in semi-outdoor scenarios.

[0010] When the dimming glass is applied to the semi-outdoor scenario, the fully laminated dimming film assembly can be configured to be laminated to the screen assembly.

[0011] Furthermore, the first glass layer is the outer glass layer facing sunlight, and the second glass layer is the inner glass layer.

[0012] Furthermore, the hollow interior of the spacer assembly is provided with an inert gas; the spacer assembly is also provided with a spacer device for connecting the first glass layer and the second glass layer.

[0013] Furthermore, the screen assembly includes a touchscreen and a transparent OLED screen:

[0014] The touch screen is attached to the second glass layer and serves as a medium for human-computer interaction to receive dimming instructions from the user; the transparent OLED screen is attached to the touch screen and is used to display information corresponding to the dimming glass.

[0015] Furthermore, the barrier film is composed of a water and oxygen barrier material to prevent malfunctions caused by chemical reactions between the dimming glass and water and oxygen in the air when it is in use.

[0016] Furthermore, the optical adhesive is composed of UV-resistant optical adhesive material to prevent damage to the dimming glass caused by sunlight exposure.

[0017] Furthermore, the output end of the fully laminated dimming film assembly includes a flexible circuit board and an electronic wire harness.

[0018] Furthermore, when the output end is configured as an electronic wire bundle, the electronic wire bundle is located between the optical adhesive and the dimming film.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. Based on the embodiments of this application, every other embodiment obtained by those skilled in the art without inventive effort falls within the scope of protection of this application.

[0029] Research has found that currently, existing dimming film glass products mainly use glass lamination solutions including EVA, TPU, or PVB. However, the glass lamination process for dimming film glass products requires specific temperature and pressure ranges, and the laminated products need to be laminated in a vacuum-sealed space with appropriate operating time and conditions.

[0030] In response to the above situations, the laminating materials are highly sensitive to temperature, pressure and time. The lamination process is prone to defects such as bubbles, foreign objects, misalignment, poor adhesive layer, delamination of the dimming film and adhesive overflow, resulting in a low yield rate of dimming film glass products. In addition, dimming film glass products are highly sensitive to water and oxygen and prolonged exposure to sunlight reduces the stability and service life of dimming film glass products.

[0031] Based on this, this application provides a dimming glass based on a fully laminated dimming film. By setting a fully laminated dimming film in the dimming glass, the characteristics of the optical adhesive and barrier film in the fully laminated dimming film are utilized to solve the problem of failure caused by the dimming glass being exposed to the air for a long time and reacting chemically with water and oxygen in the air. It also reduces the loss caused by the dimming glass being exposed to sunlight for a long time, and improves the stability and service life of the dimming film glass product.

[0032] Please see Figure 1 , Figure 1 This is one of the structural schematic diagrams of a dimming glass based on a fully laminated dimming film provided in an embodiment of this application. For example... Figure 1 As shown in the figure, the dimming glass 10 based on the fully laminated dimming film provided in this application embodiment includes a fully laminated dimming film assembly 110, a first glass layer 120, a second glass layer 130, a spacer assembly 140, and a screen assembly 150.

[0033] The spacer assembly 140 is located between the first glass layer 120 and the second glass layer 130, and the screen assembly 150 and the fully laminated dimming film assembly 110 are both disposed in the spacer assembly 140.

[0034] The screen assembly 150 is attached to the second glass layer 130, and the fully laminated dimming film assembly 110 is attached to the first glass layer 120.

[0035] Furthermore, the fully laminated dimming film assembly 110 includes a dimming film 111, a barrier film 112, an optical adhesive 113, and a sealant 114.

[0036] The dimming film 111 and the barrier film 112 are bonded together by the optical adhesive 113, and the sealant 114 is used to seal the edges of the dimming film 111, the optical adhesive 113 and the barrier film 112.

[0037] In this embodiment, the core function of the dimming film 111 is to rapidly change its optical state through an external signal (e.g., electricity) and switch seamlessly between transparent and opaque (e.g., fogging).

[0038] Here, the dimming film 111 can receive dimming control signals from the main control chip to perform corresponding dimming.

[0039] For example, the dimming film 111 is typically composed of two transparent conductive films sandwiching a layer of liquid crystal polymer composite material, encapsulated between a PET or glass substrate. When the dimming film 111 is in an off-state (foggy / opaque), the liquid crystal molecules are randomly arranged, and light is scattered when it passes through, presenting a frosted glass-like milky white or fogged effect. When the dimming film 111 is in an on-state (transparent), an AC voltage can be applied, and the liquid crystal molecules are arranged in an orderly manner under the action of the electric field, allowing light to pass through directly, presenting a highly transparent state to achieve a clear viewing effect.

[0040] In one possible implementation of this application, the dimming glass 10 is applied in outdoor scenarios, that is, when the fully laminated dimming film assembly 110 is laminated to the first glass layer 120, the fully laminated dimming film assembly 110 is closer to the area exposed to sunlight.

[0041] Furthermore, the dimming glass 10 is also used in semi-outdoor scenarios; when the dimming glass 10 is used in the semi-outdoor scenario, the fully laminated dimming film assembly 110 can be configured to be laminated to the screen assembly 150.

[0042] Here, the outdoor scene may include a completely outdoor scene directly exposed to sunlight, and the semi-outdoor scene may include an indoor scene where sunlight is irradiated by a medium such as a window or curtain. In both the semi-outdoor and outdoor scenes, water vapor, heat, and ultraviolet radiation from sunlight can be considered as factors affecting the service life of the dimming glass 10.

[0043] Please see Figure 2 , Figure 2 This is a second schematic diagram of a dimming glass structure based on a fully laminated dimming film, provided as an embodiment of this application. (See attached diagram.) Figure 2 As shown, when the dimming glass 10 is applied to a semi-outdoor scene, the fully laminated dimming film assembly 110 can be set to be laminated to the screen assembly 150. Specifically, the dimming film 111 in the fully laminated dimming film assembly 110 is laminated to the screen assembly 150, and the other structures and connections of the fully laminated dimming film assembly 110 remain unchanged.

[0044] Furthermore, such as Figure 1As shown, the first glass layer 120 is the outer glass layer facing sunlight, and the second glass layer 130 is the inner glass layer.

[0045] In this embodiment, the first glass layer 120 can be physically tempered glass or chemically tempered laminated glass. Both the first glass layer 120 and the second glass layer 130 can be subjected to low-emissivity coating treatment, or, depending on actual needs, the first glass layer 120 and the second glass layer 130 can be exempted from low-emissivity coating treatment.

[0046] For further details, please refer to Figure 3 , Figure 3 This is the third schematic diagram of a dimming glass structure based on a fully laminated dimming film, provided as an embodiment of this application. Figure 3 As shown, the hollow interior of the spacer assembly 140 is provided with an inert gas 141.

[0047] Here, the inert gas 141 may include argon and nitrogen, etc., and the inert gas 141 plays a role in noise elimination and heat control.

[0048] The spacer assembly 140 is further provided with a spacer device 142, which is used to connect the first glass layer 120 and the second glass layer 130.

[0049] Here, the spacer 142 may include an aluminum spacer bar, and a drying material is disposed in the spacer 142.

[0050] Furthermore, such as Figure 3 As shown, the screen assembly 150 includes a touch screen 151 and a transparent OLED screen 152.

[0051] The touch screen 151 is attached to the second glass layer 130 and serves as a medium for human-computer interaction to receive dimming instructions from the user; the transparent OLED screen 152 is attached to the touch screen 151 and is used to display information corresponding to the dimming glass 10.

[0052] Among them, the touch screen 151 is one of the media for adjusting the dimming signal of the dimming glass 10.

[0053] For further details, please refer to Figure 4 , Figure 4 This is a schematic diagram of the structure of a fully laminated dimming film assembly provided in an embodiment of this application. An overall view of the fully laminated dimming film assembly 110 provided in this embodiment of the application is shown below. Figure 4As shown, the fully laminated dimming film assembly 110 includes a dimming film 111, a barrier film 112, an optical adhesive 113, and a sealant 114. The dimming film 111 and the barrier film 112 are bonded together by the optical adhesive 113, and the sealant 114 is used to seal the edges of the dimming film 111, the optical adhesive 113, and the barrier film 112.

[0054] Furthermore, such as Figure 4 As shown, the barrier film 112 is composed of a water and oxygen barrier material, used to prevent the dimming glass 10 from malfunctioning due to chemical reaction with water and oxygen in the air when it is in use.

[0055] Here, the effects of water and oxygen on the dimming glass 10 are mainly reflected in oxidation and performance degradation. Specifically, oxidation leads to a decrease in performance. Metal materials (such as silver and copper) in the dimming glass 10 are prone to react with oxygen in a humid environment to generate oxides (such as silver oxide and copper green), which leads to a decrease in the conductivity and light transmittance of the dimming glass 10. For example, after the silver-based dimming film is oxidized, a brown-black oxide layer is formed on the surface, which significantly reduces the uniformity of light transmission.

[0056] Moisture accelerates the oxidation process. The presence of moisture will accelerate the oxidation rate of metals. For example, free chlorine, ozone and other oxidizing substances in a humid environment will chemically react with the material of the dimming glass 10, destroy the structure of the dimming glass 10 and cause optical performance degradation.

[0057] Mechanical properties deteriorate, and the stress generated by oxidation can cause the film layer of the dimming glass 10 to crack and peel off, reducing its flexibility. For example, after the aluminum-based dimming film is oxidized, it expands in volume, generating compressive stress and weakening its mechanical strength.

[0058] Optical performance deteriorates, and oxidation products (such as silver oxide) may absorb or scatter light, resulting in a decrease in the light transmittance of the dimming glass 10, while also forming color spots that affect the display effect.

[0059] Furthermore, such as Figure 4 As shown, the optical adhesive 113 is composed of UV-resistant optical adhesive material and is used to prevent damage to the dimming glass 10 caused by sunlight exposure.

[0060] Here, the problems caused by ultraviolet radiation include: the decomposition of the liquid crystal molecular structure of the screen assembly 150, reducing the contrast and color accuracy of the screen assembly 150, and long-term exposure can also cause uneven screen brightness; the polarizer (the component that controls the direction of light) in the dimming film 111 may yellow, crack or fade under the action of ultraviolet radiation, resulting in blurred images and color distortion; the backlight components (such as light guide plates, diffuser plates, and optical films) in the dimming film 111 will also experience decreased brightness or uneven illumination due to performance degradation caused by ultraviolet radiation.

[0061] Furthermore, the output end of the fully laminated dimming film assembly 110 includes a flexible circuit board and an electronic wire harness.

[0062] Here, the output end of dimming film products usually has step differences and sealing problems at the output position. Using optical adhesive with ordinary adhesive layer thickness cannot fill the wire harness step difference, and will form a dent on the surface of the optical adhesive.

[0063] In this embodiment, when the output terminal is set as a flexible circuit board, the flat wire design of the flexible circuit board does not need to deal with the step difference problem. When the output terminal is set as an electronic wire harness, the electronic wire harness will affect the wire diameter and height of the optical adhesive.

[0064] For further details, please refer to Figure 5 , Figure 5 This is a schematic diagram illustrating the arrangement of an electronic wire harness according to an embodiment of this application. Figure 5 As shown in the figure. When the output end is configured as electronic wire bundle 115, the electronic wire bundle 115 is located between the optical adhesive 113 and the dimming film 111.

[0065] In this embodiment, an optical adhesive 113 with high ductility and a relatively thick thickness (e.g., a thickness greater than 1.25 times the diameter of the wire harness) is used for bonding, making full use of the wetting characteristics of the optical adhesive 113 so that the exit position of the electronic wire harness 115 can be effectively sealed and bonded.

[0066] This application provides a dimming glass based on a fully laminated dimming film. By setting a fully laminated dimming film in the dimming glass, the characteristics of the optical adhesive and barrier film in the fully laminated dimming film are utilized to solve the problem of failure caused by the dimming glass being exposed to the air for a long time and reacting chemically with water and oxygen in the air. It also reduces the loss caused by the dimming glass being exposed to sunlight for a long time, and improves the stability and service life of the dimming film glass product.

[0067] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the methods, systems, devices, and units described above can be referred to the corresponding processes in the foregoing device embodiments, and will not be repeated here.

[0068] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The scope of protection of this application is not limited thereto.
