Detailed Implementation
[0020] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.
[0021] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.
[0022] As described in the background section, intelligent glass typically possesses functions such as light emission, heat generation, display, and touch control. In some embodiments, intelligent glass includes a first transparent substrate, a first adhesive layer, a functional layer, and a second adhesive layer stacked sequentially. To prevent the functional layer from reacting with the first or second adhesive layer during long-term use and thus affecting the reliability of the glass, the material selection for the first and second adhesive layers is relatively limited. For example, if both the first and second adhesive layers have high transmittance, the transmittance design cannot be met. When other adhesive layers are added, the applicant finds that the added adhesive layers react with the functional layer, leading to problems such as discoloration and short circuits in the appearance of the stacked components after high-temperature aging.
[0023] Based on this, in an exemplary embodiment, as shown in FIG1, this application provides a stacked component, including a first transparent substrate 2, a first adhesive layer 4, a functional layer 6, a second adhesive layer 8, a partition layer 10, a third adhesive layer 12, and a second transparent substrate 14 stacked sequentially.
[0024] The partition layer 10 can be used to separate the second adhesive layer and the third adhesive layer 12 to prevent the third adhesive layer 12 from penetrating into the second adhesive layer 8.
[0025] For example, as described above, the selection of materials for the first and second adhesive layers cannot meet the diverse transmittance design requirements of smart glass. To achieve these diverse transmittance design requirements, a third adhesive layer 12 and a second adhesive layer 8 with different transmittance can be directly stacked and bonded together to change the transmittance of the laminated component. However, after powering the laminated component constructed in the above manner with a 12V DC power supply for 1000 hours and placing it in an environment of 50℃-90℃ for reliability testing, it was found that when the third adhesive layer 12 and the second adhesive layer 8 with different transmittance are directly stacked and bonded together, the laminated component exhibits reliability issues such as discoloration. The inventors' research revealed that when directly stacked and bonded, harmful components in the third adhesive layer 12 (chloride ions, water molecules, oxygen molecules, special functional groups such as hydroxyl groups, catalysts, etc.) can penetrate through the second adhesive layer 8 to the functional layer 6 and react with it, causing ion migration and resulting in discoloration and functional failure of the functional layer 6. Clearly, directly stacking the third adhesive layer 12 and the second adhesive layer 8 for bonding cannot guarantee the reliability of the laminated component while meeting diverse transmittance design requirements. Changing the adhesive material of the third adhesive layer 12 further limits the selection due to its specific properties; redesigning and customizing it increases R&D and manufacturing costs and requires extensive reliability verification, which is time-consuming and labor-intensive; increasing the thickness of the second adhesive layer 8 also fails to meet the transmittance design requirements. Therefore, as shown in Figure 1, this application adds a partition layer 10 between the third adhesive layer 12 and the second adhesive layer 8 to prevent the adhesive material in the third adhesive layer 12 from directly entering the second adhesive layer 8 and causing reliability issues. The partition layer 10 can be made of transparent films with different transmittance values, depending on the transmittance requirements. Moreover, when the stacked component shown in Figure 1 is subjected to the reliability high-temperature operation verification as described above, since the third adhesive layer 12 and the second adhesive layer 8 are separated by the partition layer 10, the material of the third adhesive layer 12 cannot directly contact the functional layer 6 and react. Based on this, the material transmittance of the third adhesive layer can be selected more flexibly, and can be selected according to the actual application scenario, without being limited by the material characteristics. This ensures the reliability of the stacked component while meeting the diverse transmittance design requirements of the stacked component.
[0026] The aforementioned laminated assembly, by adding a partition layer between the third and second adhesive layers, effectively prevents reliability issues caused by direct contact and reaction between the third adhesive layer material and the functional layer. It also allows for the selection of transparent films with different transmittance as the partition layer and adhesive materials with different transmittance as the third adhesive layer, based on transmittance requirements. This satisfies the diverse transmittance design needs of laminated assemblies without sacrificing the stability of the functional layers, achieving a dual improvement in functionality and reliability. This not only solves the technical challenges of traditional stacking methods but also avoids high R&D costs and lengthy reliability verification processes, providing an efficient and economical solution for applying laminated assemblies to automotive glass.
[0027] In one embodiment, the first adhesive layer 4 and / or the second adhesive layer 8 shown in FIG1 are used to inhibit or slow down ion migration in the functional layer.
[0028] Among them, materials that can inhibit or slow down ion migration in the functional layer can be materials that do not contain chloride ions, water molecules, oxygen molecules, special functional groups hydroxyl groups, catalysts, or have extremely low content. Such materials can work under high voltage or high current at room temperature, or under low voltage or low current in a high-temperature test chamber (without limitation on the high temperature range), and after aging for more than 1000 hours, the appearance does not change color and the conductivity is normal.
[0029] In an exemplary embodiment, the first adhesive layer 4 and / or the second adhesive layer 8 may be a monolayer structure made of a material capable of inhibiting or slowing down ion migration in the functional layer.
[0030] In an exemplary embodiment, the first adhesive layer 4 and / or the second adhesive layer 8 may also be a multilayer composite structure made of a material capable of inhibiting or slowing down ion migration in the functional layers.
[0031] For example, based on the fact that the setting of the partition layer meets the transmittance design requirements, one of the first adhesive layer 4 and the second adhesive layer 8 can adopt a single-layer or multi-layer composite structure made of a material that can suppress or slow down ion migration in the functional layer, depending on the functional form of the actual product; or both the first adhesive layer 4 and the second adhesive layer 8 can adopt a single-layer or multi-layer composite structure made of a material that can suppress or slow down ion migration in the functional layer. While ensuring the normal appearance and function of the laminated component, the material selection of the adhesive layer can be further optimized to meet a wider range of transmittance design requirements and process design requirements.
[0032] In an exemplary embodiment, the material used in the first adhesive layer 4 and / or the second adhesive layer 8 shown in FIG. 1, capable of inhibiting or slowing down ion migration in the functional layer, can be at least one of ethylene-vinyl acetate copolymer, polyethylene octene elastomer, water-based adhesive, and optically transparent adhesive. Such materials possess good chemical resistance and electrical insulation, and are not prone to reacting with metal atoms in the functional layer 6, thus effectively preventing metal atom migration. Simultaneously, such materials can flow and cure under heating conditions, making them suitable for thermoforming processes. This helps to form a dense and uniform adhesive layer, improving the overall strength and sealing of the entire laminated assembly.
[0033] In addition, further research by the inventors revealed that the reliability issues of intelligent glass under long-term operation are mainly discoloration and short circuits. The main reason for discoloration is that, in order to achieve functions such as light emission, display, heat generation, and touch control, an conductive layer is set in the intelligent glass. Under the influence of electric field force, the metal atoms on the conductive layer react with the adhesive material of the intelligent glass during long-term operation. The metal atoms are corroded by harmful components such as water molecules, chloride ions, and catalysts in the adhesive material and transformed into ionic form. Under the combined action of voltage and high temperature, the metal atoms move from the positive to the negative electrode in ionic form at an accelerated rate. The unevenly distributed ions between the positive and negative electrodes form micro-short circuits, which leads to discoloration and short circuits in the intelligent glass.
[0034] For the reasons mentioned above, in an exemplary embodiment, as shown in FIG2, this application provides a stacked assembly, which includes a first transparent substrate 2, a first adhesive layer 4, a functional layer 6, a second adhesive layer 8, and a second transparent substrate 14 stacked sequentially. A conductive layer 62 is provided on the surface of the functional layer 6 near the second adhesive layer 8, and the second adhesive layer 8 is used to suppress or slow down ion migration in the conductive layer 62.
[0035] The material that can suppress or slow down ion migration in the conductive layer 62 can be a material that can operate under high voltage or high current at room temperature, or under low voltage or low current in a high-temperature test chamber (without limitation on the high temperature range), and remain unchanged in appearance and have normal conductivity after aging for more than 1000 hours. The first transparent substrate 2 and the second transparent substrate 14 can be glass substrates. The functional layer 6 can be a structural layer with functions such as light emission, display, heat generation, and touch control. As shown in Figure 1, a conductive layer 62 is provided on the surface of the functional layer 6 near the second adhesive layer 8. This conductive layer 62 can be a metal mesh conductive film. This type of metal mesh conductive film is mainly formed by growing conductive metal mesh patterns on glass or organic polymer plastic films using metal materials such as silver and copper, and has the characteristics of low resistivity and good bending resistance. The conductive layer 62 can also be an ITO (indium tin oxide) film; the conductive layer 62 can also be a nano-silver wire laminated film, etc. In addition, the functional layer 6 may also be provided with a flexible wire connection device 64 to connect to the conductive layer 62, so that the conductive layer 62 can be connected to the driver board through the flexible wire connection device 64, thereby realizing functions such as light emission, display, heat generation and touch control.
[0036] For example, the stacked assembly is composed of a first transparent substrate 2, a first adhesive layer 4, a functional layer 6 (including a conductive layer 62), a second adhesive layer 8, and a second transparent substrate 14 stacked sequentially. During the bonding of the stacked assembly, the first adhesive layer 4 does not contact the conductive layer 62. The material selection for the first adhesive layer 4 can be based on requirements such as transmittance and lamination process. For example, adhesive materials containing chloride ions, water molecules, oxygen molecules, special functional groups (hydroxyl groups), catalysts, etc. (e.g., PVB) can be used; the specific material type is not limited here. The second adhesive layer 8, which is in direct contact with the conductive layer 62, is made of a material capable of inhibiting or slowing down ion migration in the conductive layer 62. Because this material does not contain chloride ions, water, special functional groups (hydroxyl groups), catalysts, etc., or contains them in extremely low proportions, it can effectively prevent or slow down the problem of metal atoms in the conductive layer 62 reacting with the surrounding environment and migrating from the positive to the negative electrode in ionic form under the action of an electric field during long-term energization. Based on the above-mentioned stacked components, even under long-term use and continuous power supply, the problems of appearance discoloration and short circuit caused by uneven distribution of metal atoms can be significantly reduced or even avoided.
[0037] The aforementioned laminated assembly utilizes a material capable of suppressing or mitigating ion migration in the conductive layer as the adhesive material on the conductive side of the functional layer. This effectively prevents the conductive layer from reacting with the adhesive material during long-term use, thus avoiding the migration of metal atoms (such as copper and silver) in the conductive layer. This significantly reduces discoloration and short-circuit issues caused by uneven metal atom distribution, ensuring the stability and reliability of the laminated assembly under long-term operating conditions and extending its service life. Furthermore, the material of the second adhesive layer, which is in direct contact with the conductive layer, is limited, while the material selection for the first adhesive layer is more flexible. This ensures the reliability of the laminated assembly when used as automotive glass, while also meeting different transmittance design requirements or process design requirements to a certain extent.
[0038] In one exemplary embodiment, the second adhesive layer 8 may be a single-layer or multi-layer composite structure made of a material capable of inhibiting or slowing down ion migration in the conductive layer 62.
[0039] In an exemplary embodiment, the material of the second adhesive layer 8 shown in FIG. 2 is at least one selected from ethylene-vinyl acetate copolymer, polyethylene octene elastomer, water-based adhesive, and optically transparent adhesive. Such materials exhibit good chemical resistance and electrical insulation, and are not prone to reacting with metal atoms in the conductive layer 62, thus effectively preventing metal atom migration. Furthermore, these materials can flow and cure under heating conditions, making them suitable for thermoforming processes. This facilitates the formation of a tight and uniform adhesive layer, improving the overall strength and sealing of the entire laminated assembly.
[0040] In this embodiment, a material capable of inhibiting or slowing down ion migration in the conductive layer is selected as the material of the second adhesive layer. Based on the ability of this type of material to inhibit or slow down ion migration in the conductive layer, as well as its comprehensive excellent mechanical properties, chemical stability and processing characteristics, the stacked component of this application can effectively solve the problems of appearance discoloration and short circuit, thereby ensuring the long-term reliability of the product.
[0041] In one exemplary embodiment, the transmittance of the third adhesive layer 12 is different from that of the second adhesive layer 8.
[0042] For example, in the above embodiments, by setting the partition layer 10, the reliability of the laminated assembly is ensured while the diverse transmittance design requirements of the laminated assembly are met. However, when the laminated assembly is used as automotive glass in automobiles, since the materials of the first adhesive layer 4 and the second adhesive layer 8, which meet the above reliability requirements, are mostly transparent, their transmittance is usually high (around 90%), which cannot meet the transmittance requirements of automotive glass (such as the windshield requiring a transmittance of no less than 70%, while door glass, sunroof, and rear windshield are designed according to transmittance requirements). Therefore, it is necessary to select a material with lower transmittance as the third adhesive layer 12 to change the overall transmittance of the laminated assembly, thereby adapting to the different transmittance requirements of different automotive glass.
[0043] In this embodiment, by introducing a third adhesive layer with lower transmittance, the overall transmittance of the laminated component is effectively adjusted so that it can meet the specific transmittance requirements of automotive glass. This satisfies the different light transmittance requirements of different types of automotive glass (such as windshield, door glass, sunroof, and rear windshield), optimizes optical performance while ensuring safety performance, and provides automakers with more flexible design options.
[0044] In one exemplary embodiment, the partition layer 10 may be a film layer made of a thin film material with high transmittance and low haze. Optionally, the partition layer 10 may be a single-layer structure made of a thin film material with high transmittance and low haze, or the partition layer 10 may be a multilayer composite structure made of a thin film material with high transmittance and low haze.
[0045] Among them, thin film materials with high transmittance and low haze need to meet the conditions of working under high voltage or high current at room temperature, or working under low voltage or low current in a high-temperature test chamber (without limitation of high temperature range), and aging for more than 1000 hours without changing color or functioning normally.
[0046] In an exemplary embodiment, the partition layer 10 shown in FIG1 is an organic polymer film. Using an organic polymer film (such as PET film) as the material not only effectively isolates the third adhesive layer 12 from the functional layer 6, preventing discoloration and short circuits caused by metal atom migration due to chemical reactions, but also meets the specific optical performance requirements of automotive glass due to its good transparency and adjustable transmittance.
[0047] In an exemplary embodiment, as shown in FIG3, the functional layer 6 includes a third transparent substrate 66, a conductive layer 62 and a Mini-LED pixel array 68 stacked sequentially; the third transparent substrate 66 is adjacent to the first adhesive layer 4.
[0048] For example, the conductive layer 62 can be a metal mesh conductive film, an ITO film, or a transparent silver nanowire film. In addition, the functional layer 6 can also be provided with a flexible wire connection device 64 connected to the conductive layer 62, so that the conductive layer 62 can be connected to the driving board via the flexible wire connection device 64. The specific stacking relationship of the third transparent substrate 66, the conductive layer 62, and the Mini-LED pixel array 68 is shown in Figure 3. By sequentially constructing the conductive layer 62 and the Mini-LED pixel array 68 on the third transparent substrate 66, the functional layer 6 can realize the light-emitting or display function based on the Mini-LED pixel array 68.
[0049] In this embodiment, by sequentially stacking a metal mesh conductive film and a Mini-LED pixel array on a third transparent substrate, not only is efficient current transmission and uniform light distribution achieved, but also high brightness and high contrast display effects based on the Mini-LED pixel array are ensured, supporting finer image display and higher energy efficiency ratio, while maintaining good transparency. This makes it suitable for application scenarios that require high-quality display and light transmittance, such as automotive displays or transparent displays.
[0050] In an exemplary embodiment, the third transparent substrate 66 shown in FIG3 is an organic polymer film.
[0051] For example, the third transparent substrate 66 is made of an organic polymer film (such as PET film), which has advantages such as being thin, flexible, and having good optical transparency. This not only helps to improve the flexibility and durability of the entire stacked assembly, but also effectively reduces the overall weight and simplifies the manufacturing process. Moreover, with the organic polymer film as the third transparent substrate 66, the material selection for the first adhesive layer 4 is more flexible. It can be a material with high transmittance that can inhibit or slow down ion migration in the conductive layer 62 and is free of chloride ions, water molecules, oxygen molecules, special functional groups (hydroxyl groups), catalysts, or has extremely low content. Alternatively, it can be an adhesive material with low transmittance containing chloride ions, water molecules, oxygen molecules, special functional groups (hydroxyl groups), catalysts. The specific material selection can be determined according to the transmittance design requirements, and will not be listed here. In addition, the use of organic polymer films can also provide excellent chemical resistance and environmental aging resistance, thereby ensuring the stability and reliability of the Mini-LED pixel array 68 and the conductive layer 62 under long-term working conditions, making it suitable for applications with high requirements for display quality and long-term performance.
[0052] In an exemplary embodiment, as shown in FIG4, at least one side of the partition layer 10 has haze diffusion particles 102.
[0053] For example, a haze diffusion film is formed by coating one side of the partition layer 10 with white haze diffusion particles 102, or by coating both sides of the partition layer 10 with white haze diffusion particles 102, wherein the amount of haze diffusion particles 102 coated on one side is greater than that on the other side. These particles can effectively scatter light, so that the light emitted by the Mini-LED lamp beads is evenly diffused when passing through this film, thereby reducing the graininess and glare of individual Mini-LED light sources, improving the softness and uniformity of the overall display effect. At the same time, the haze diffusion film has a masking effect on the graininess of the Mini-LED lamp beads, which not only improves the visual experience, but also enhances the appearance quality of the Mini-LED display panel, making it more suitable for application scenarios that require a high-quality and comfortable viewing experience.
[0054] In an exemplary embodiment, as shown in FIG5, one side of the partition layer 10 has a prism microstructure 104.
[0055] In this design, the prism microstructure 104 on the partition layer 10 is located on the light-emitting side of the Mini-LED to change the propagation direction of the light emitted by the Mini-LED, thereby achieving a light-focusing effect. For example, by fabricating the prism microstructure 104 on the upper surface of the partition layer 10, a brightness enhancement film with a light-focusing effect can be formed. This prism-like microstructure can change the propagation direction of the light emitted by the Mini-LED, concentrating the light that would otherwise be scattered in various directions and guiding it to a specific angle, thereby improving the brightness from a frontal viewing angle. The partition layer 10 with the prism microstructure 104 not only enhances the overall brightness of the Mini-LED, making the Mini-LED light source more efficient, but also reduces unnecessary side light loss, achieving energy-saving effects, while simultaneously improving the visual experience and display efficiency.
[0056] In an exemplary embodiment, the partition layer 10 shown in FIG6 can be a colored organic polymer film.
[0057] For example, by using a colored organic polymer film as the separator layer 10, the color of the light emitted by the Mini-LED is changed by utilizing its specific color filtering properties. When the light emitted by the white Mini-LED light beads passes through this colored organic polymer film, the film absorbs or reflects unwanted wavelengths, allowing only specific colors of light to pass through. This results in the final displayed light exhibiting a color that matches the film color, enabling rich color performance and simplifying the design that traditionally requires a separate color filter. This improves manufacturing efficiency and cost-effectiveness, making it suitable for applications requiring multi-color display effects.
[0058] In one exemplary embodiment, the partition layer 10 shown in FIG7 may include a touch film.
[0059] For example, the partition layer 10 uses a touch film in conjunction with a flexible wire connector 64. Based on the touch sensing and other related characteristics of the touch film itself, a touch display function can be realized by combining it with the Mini-LED pixel array 68. For example, a user can touch the surface of the touch film with their finger to trigger a corresponding touch signal. This signal can be accurately recognized by the system and a corresponding response can be made. For example, it can realize operations such as switching the display screen, zooming the display content, and clicking relevant icons to open the corresponding application. This greatly enhances the human-computer interaction experience, makes the interaction between people and devices more intuitive and convenient, and improves the practicality and ease of use of the entire device in actual use.
[0060] In one exemplary embodiment, the partition layer 10 shown in FIG7 may include a heating film. For example, the partition layer 10 may be a transparent heating film.
[0061] For example, in rainy or foggy weather, the high moisture content in the air causes water vapor to easily adhere to the surface of the transparent substrate, condensing into fog or frost. When the laminated assembly is used as automotive glass, this fog and frost can obscure the Mini-LED display, resulting in unclear visibility. This is extremely detrimental to driving safety, as drivers may be unable to accurately and clearly access important information such as navigation and vehicle status alerts through the in-vehicle display, potentially leading to accidents. When the clarity of the Mini-LED display is affected by fog or frost, the partition layer 10 uses a transparent heating film, which can be activated for heating. The transparent heating film heats up after being powered on, transferring heat to the glass surface. This causes the fog adhering to the glass to evaporate, and the frost to gradually melt and dissipate, restoring clarity to the glass surface and allowing the Mini-LED display to be clearly displayed again. In this way, drivers can clearly see the relevant display information, which greatly improves driving safety and ensures that vehicles can drive normally and safely in adverse weather conditions.
[0062] In an exemplary embodiment, the partition layer 10 shown in FIG7 may further include a touch film and a heating film. The working process and related beneficial effects of the touch film and the heating film can be found in the description of the preceding embodiments, and will not be repeated here.
[0063] In an exemplary embodiment, as shown in FIG8, the functional layer 6 further includes a heating layer 69 disposed between the third transparent substrate and the conductive layer.
[0064] For example, by adding a heating layer 69, the functional layer 6 can not only realize the original light emission and display functions based on the Mini-LED pixel array 68, but also has the functions of heating to defrost, defrost, and maintaining its own temperature in low-temperature environments to ensure the stability of display and other related performance. This makes it more suitable for use in scenarios such as outdoor and automotive environments that may face complex environmental conditions such as low temperature and high humidity, further improving the practicality and adaptability of the entire functional layer 6.
[0065] In one embodiment, as shown in FIG9, the functional layer 6, the second adhesive layer 8, and the partition layer 10 constitute a membrane assembly based on a pre-encapsulation process.
[0066] During the manufacturing process, the functional layer 6, the second adhesive layer 8, and the partition layer 10 can be pre-encapsulated to form an integral membrane assembly (as shown in the dashed box in Figure 9). This facilitates the subsequent assembly of related products by reducing the tedious steps and time costs of installing individual components and improving production efficiency.
[0067] Based on the same inventive concept, in an exemplary embodiment, this application also provides a vehicle (not shown) including the stacked components described in the above embodiments.
[0068] It is understood that the means of transportation in the embodiments of this application can be any means of transportation that requires light transmission, such as cars, airplanes, and high-speed trains, and the embodiments disclosed in this application do not limit this.
