Description

Technical Field

[0002] Due to their excellent haze properties, PDLC (Polymer Dispersed Liquid Crystal) films containing black dye are increasingly being used in automotive glass. However, the applicant has discovered that when the PDLC film containing black dye is in the off state, users viewing the sun from inside the vehicle will notice that the sun is not white, but rather red or orange. Furthermore, if the ambient light is very strong and the vehicle interior is very dark, the PDLC film containing black dye may even appear dark red. This red or orange color often causes a negative user experience, indicating that the light rendering quality of the automotive glass is poor. Utility Model Content

[0028] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0030] It will be understood that the terms "first," "second," and the like used herein may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first bonding layer may be referred to as a second bonding layer, and similarly, a second bonding layer may be referred to as a first bonding layer. Both the first bonding layer and the second bonding layer are bonding layers, but they are not the same bonding layer.

[0031] As used herein, the singular forms "a," "an," and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include," "comprising," "having," and the like specify the presence of stated features, integers, steps, operations, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, parts, or combinations thereof. Furthermore, the term "and / or" as used in this specification includes any and all combinations of the relevant listed items.

[0032] As described in the background art, based on the advantages of neutral color and good haze of the PDLC film containing black dye, it can well protect user privacy when applied to vehicle glass.

[0033] The production process of PDLC film containing black dye is as follows: black dye (usually dichroic dye), liquid crystal and polymer monomer are mixed in a certain proportion. After polymerization reaction, the black dye and liquid crystal are phase separated from the polymer, and the black dye and liquid crystal form liquid crystal droplets dispersed in the polymer matrix.

[0034] like Figure 1 As shown, the black dye-containing PDLC film 30 includes a first electrical substrate 31, a second electrical substrate 32, a polymer substrate 33, and liquid crystal droplets. The liquid crystal droplets are dispersed in the polymer substrate 33 and contain liquid crystal molecules 34 and dichroic dye molecules 35. When no power is applied, the liquid crystal molecules 34 and dichroic dye molecules 35 in the liquid crystal droplets are arranged in a bipolar pattern, and the axial directions of each liquid crystal droplet are different, facing in different directions. At this time, the refractive index of the liquid crystal droplet is not equal to the refractive index of the polymer substrate 33. At this time, when light passes through the black dye-containing PDLC film 30, part of the light is absorbed by the dichroic dye 35 in the liquid crystal droplets, and part is scattered by the liquid crystal droplets (e.g., Figure 1 As shown in the scattered light 8), part of it is vertical (as shown in the scattered light 8). Figure 1 The transmitted light ray 9) passes through.

[0035] Figure 2 This diagram shows the light path of the sun as seen by the human eye through a PDLC film 30 containing a black dye. When sunlight passes through the PDLC film 30 containing a black dye, red and orange light are less likely to be scattered than other colors due to their relatively low refractive index. Furthermore, the absorption effect of the dichroic dye 35 causes a relatively large proportion of red and orange light in the vertically passing light. When the sun's rays are strong, more vertically transmitted light 9 passes through, and the human eye perceives a high intensity of red and orange light, causing the sun to appear red or orange. If the sunlight outside the vehicle is very strong and the interior of the vehicle is very dark, the PDLC film 30 containing a black dye may even appear dark red when viewed from inside. This shows that conventional automotive glass with a PDLC film containing a black dye exhibits poor light rendering.

[0036] In view of this, in one embodiment, a laminated component is provided, such as Figure 1 As shown, it includes: a first transparent substrate 10 , a first adhesive layer 50 , a PDLC film 30 containing black dye, a complementary film 40 , and a second transparent substrate 20 , which are stacked.

[0037] Among them, Figure 3In the viewing angle shown, the complementary film 40 is disposed on the second transparent substrate 20 , the PDLC film 30 containing black dye is disposed on the complementary film 40 , the first adhesive layer 50 is disposed on the PDLC film 30 containing black dye, and the first transparent substrate 10 is disposed on the first adhesive layer 50 .

[0038] The complementary film 40 is a film that appears bluish-green when sunlight passes through it. This means that the complementary film 40 supports a bluish-green color when sunlight passes through it. The complementary film 40 may also support other functions, depending on the material selected for the complementary film 40. The complementary film 40 may have a single-layer structure or a multi-layer structure.

[0039] The first transparent substrate 10 and the second transparent substrate 20 are substrates that are light-transmissive and can provide a certain degree of support. For example, the first transparent substrate 10 and the second transparent substrate 20 can be, but are not limited to, glass plates or polycarbonate (PC) plates.

[0040] Specifically, such as Figure 3 As shown, by providing a complementary film 40 between the black dye-containing PDLC film 30 and the second transparent substrate 20, when the black dye-containing PDLC film 30 is in the off state, the sun appears white when viewed through the laminated module, closer to natural light and more pleasing to the senses. Furthermore, with the addition of the complementary film 40, when viewing areas other than the sun through the laminated module, the entire laminated module appears dark blue-green to the human eye, creating the illusion of a white sun and blue sky, enhancing the laminated module's light rendering quality.

[0041] The laminated component provided in the example of this application utilizes the principle of complementary colors. The complementary color of red is green, and the complementary color of yellow is blue. By adding a complementary film 40, the problem of the sun appearing red or orange through the PDLC film 30 containing black dye is solved. The sun seen by the human eye through the laminated component appears white, which is close to the natural situation, thereby ensuring the light presentation effect of the laminated component.

[0042] In one embodiment, Figure 3 As shown, the complementary film 40 is a turquoise film.

[0043] Among them, the complementary film 40 may include a combination of one or more of ionomer (SGP, Sentry Glas Plus), polyvinyl butyral (PVB, Polyvinyl Butyral), sound insulation PVB, shading tape PVB, heat control PVB, ethylene vinyl acetate (EVA, Ethylene Vinyl Acetate Copolymer), thermoplastic polyurethane (TPU, Thermoplastic Polyurethane), ionomer, thermoplastic material, polybutylene terephthalate (PBT, Polybutylene Terephthalate‌), polyethylene naphthalate (PEN, Polyethylene Naphthalate), polyvinyl chloride (PVC, Polyvinyl chloride), polyvinyl fluoride (PVF, vinyl fluoride), polyacrylate (PA, Polyacrylate), polymethyl methacrylate (PMMA, Polymethyl Methacrylate) and polyurethane (PUR, Polyurethane).

[0044] By selecting a blue-green complementary film 40 (meaning the color of the film seen by the human eye when sunlight passes through is blue-green), and utilizing the fact that green complements red and blue complements yellow, the sunlight seen by the human eye through the laminated module appears white light, which is close to the natural state, thereby ensuring the light presentation effect of the laminated module.

[0045] In one example, the complementary film 40 is a blue-green PVB film or EVA film or other adhesive film.

[0046] When the complementary film 40 is blue-green PVB or EVA, it can act as a bonding layer due to its adhesiveness, thereby achieving the combination of the PDLC film 30 containing black dye and the second transparent substrate 20 .

[0047] In one embodiment, when the complementary film 40 is a blue-green film, the chromaticity value range of the complementary film 40 is -70≤a*≤-30 and -40≤b*≤-10; and / or the visible light transmittance of the complementary film 40 is in the range of 5% to 40%; and / or the haze of the complementary film 40 is less than or equal to 5%.

[0048] The diaphragm colorimetric values ​​include a* and b*. a* represents red and green, and its value changes from positive to negative, indicating a color shift from red (positive) to green (negative). A larger a value indicates a redder color, while a smaller a value indicates a greener color. b* represents yellow and blue, and its value changes from positive to negative, indicating a color shift from yellow (positive) to blue (negative). A larger b value indicates a yellower color, while a smaller b value indicates a bluer color.

[0049] After testing, it was found that when the chromaticity range of the complementary film 40 was -70≤a*≤-30 and -40≤b*≤-10, under different sunlight intensities, the sun observed by the human eye through the laminated module was white, close to the natural situation, and other areas outside the sun observed by the human eye through the laminated module appeared dark blue-green, close to the natural color of the blue sky, ensuring the good light presentation effect of the laminated module.

[0050] According to requirements such as privacy protection, the visible light transmittance of the complementary film 40 can be designed to be 5% to 40%.

[0051] In the laminated component provided in the embodiment of the present application, the haze of the complementary film 40 is less than or equal to 5%. After being superimposed on the PDLC film 30 containing black dye, the laminated component as a whole still has good haze, thereby protecting user privacy.

[0052] In one embodiment, Figure 4 As shown, the complementary film 40 is an electrochromic (EC) film, which is blue-green in dark state.

[0053] The electrochromic film can change the color and transparency of the electrochromic material by applying an external electric field or current, allowing the entire electrochromic film to switch between a dark state and a transparent state. The electrochromic film provided in the embodiments of the present application is in a dark state when the PDLC film 30 containing the black dye is in the off state. The electrochromic film in the dark state has a blue-green color, which complements the red and yellow colors presented by sunlight passing through the PDLC film 30 containing the black dye. As a result, the sun ultimately appears white to the human eye through the laminated module, and other areas outside the sun appear dark blue-green, close to the natural color of the blue sky, ensuring the best light rendering effect.

[0054] In one embodiment, the chromaticity value range of the electrochromic film in the dark state is -70≤a*≤-30 and -40≤b*≤-10; and / or, the transmittance of the electrochromic film in the dark state is 5%~20%; and / or, the haze of the electrochromic film in the dark state is less than or equal to 5%.

[0055] The concepts of a* and b* are as described in the above embodiments and will not be elaborated here.

[0056] After testing, it was found that using an electrochromic film with a value of -70≤a*≤-30 and -40≤b*≤-10, under different sunlight intensities, the sun observed by the human eye through the laminated module is white, and the light rendering effect is good.

[0057] Since the electrochromic film can switch between a dark state and a transparent state, the transmittance of the electrochromic film in the dark state can be designed to be 5% to 20%, thereby better protecting the privacy of the user on one side of the laminated component.

[0058] The haze of the electrochromic film in the dark state is less than or equal to 5%. After being superimposed on the PDLC film 30 containing black dye, the stacked assembly still has good haze as a whole, thus protecting user privacy.

[0059] In one embodiment, the transmittance of the electrochromic film in a transparent state is 50% to 80%, which can ensure that when the PDLC film 30 containing black dye and the EC film both become transparent, a clearer field of view is provided to the user.

[0060] In one embodiment, Figure 4 As shown, the laminated assembly further includes a second adhesive layer 60 and a third adhesive layer 70 .

[0061] A second adhesive layer 60 is provided between the PDLC film 30 containing black dye and the complementary film 40;

[0062] The third adhesive layer 70 is disposed between the complementary film 40 and the second transparent substrate 20 .

[0063] The first transparent substrate 10, the black dye-containing PDLC film 30, the complementary film 40, and the second transparent substrate 20 are assembled by a first adhesive layer 50, a second adhesive layer 60, and a third adhesive layer 70. The second adhesive layer 60 and the third adhesive layer 70 are both transparent adhesive layers that can ensure the transmittance of the stacked assembly.

[0064] In one embodiment, the first adhesive layer 50 is a transparent adhesive layer, which can reduce the impact of the first adhesive layer 50 on the transmittance of the stacked component.

[0065] In one embodiment, at least one of the first bonding layer 50, the second bonding layer 60 and the third bonding layer 70 may include a composition of one or more of the following films: SGP, PVB, sound insulation PVB, light-shielding tape PVB, thermal control PVB, EVA, TPU, ionomer, thermoplastic material, PBT, PEN, PVC, PVF, PA, PMMA, PUR.

[0066] In one embodiment, Figure 5 As shown, the laminated component further includes a functional layer 90 .

[0067] The functional layer 90 is disposed on the first transparent substrate 10 or the second transparent substrate 20. The functional layer 90 refers to a film layer capable of achieving at least one function.

[0068] In one embodiment, Figure 5 As shown, the functional layer 90 includes at least one of a low-emissivity layer, a water-absorbing coating layer, an anti-reflection film layer, and an anti-fingerprint layer.

[0069] By providing a low-emissivity layer on the side of the first transparent substrate 10 or the second transparent substrate 20 , a heat insulating effect can be achieved, thereby improving the user experience of users located on the side of the first transparent substrate 10 or the second transparent substrate 20 .

[0070] By providing a water-absorbing coating on the first transparent substrate 10 or the second transparent substrate 20 side, condensation can be prevented.

[0071] By providing an anti-reflection film layer on the first transparent substrate 10 or the second transparent substrate 20 , the surface light reflection of the stacked module can be reduced.

[0072] By providing an anti-fingerprint layer on the first transparent substrate 10 or the second transparent substrate 20 , it is possible to prevent fingerprints from being left when a user touches the stacked component.

[0073] In one embodiment, the first transparent substrate 10 is a glass plate, and / or the second transparent substrate 20 is a glass plate. The first transparent substrate 10 and the second transparent substrate 20 may both be soda-lime-silica glass.

[0074] In one embodiment, the PDLC film 30 containing black dye has a chromaticity value of -6≤a*≤4 and -9≤b*≤3 when in the off state; and / or the visible light transmittance of the PDLC film 30 containing black dye is 3% to 8% when in the off state.

[0075] The visible light transmittance of the PDLC film 30 containing black dye in the off state is 3% to 8%, which can well protect the user's privacy in the off state.

[0076] In order to better illustrate the beneficial effects of the laminated components provided in the embodiments of the present application, comparative examples 1 to 3 in conventional technology are compared with the laminated components in embodiments 1 and 2 of the present application.
