Description

Technical Field

[0001] The present invention relates to the technical field of display systems, and in particular to a dimming component and a preparation method thereof, dimming glass, a display device and a vehicle. Background Art

[0002] Dimming refers to the use of the transmission and scattering phenomena of dimming materials to make the display transparent or opaque when the power is on or off. Currently, dimming components (such as PLDC, polymer dispersed liquid crystal) are widely used in large-area projection screens, building and car doors and windows, glass curtain walls, room interior partitions and other occasions.

[0003] Taking PLDC as an example, when PLDC is placed in laminated glass to prepare dimming glass, it needs to be bonded to the glass through a glue layer. However, the liquid crystal polymer in the light-controlling functional layer of PDLC easily reacts with the plasticizer in the glue layer, which will cause the PLDC to fail, and then cause the dimming glass to fail.

[0004] The edge sealing process can prevent the plasticizer in the glue layer from entering the light control functional layer of PLDC and reacting with the liquid crystal polymer. However, the current edge sealing process generally adopts a half-cut process, cutting out steps, and then using a glue-spraying device to glue this area, and then curing. This process has the following problems:

[0005] 1. When applying glue on the half-cut step, due to the effect of gravity, uneven glue coating is inevitable. The entire edge banding area is thin on the top and thick on the bottom, resulting in a relatively weak upper part and a risk of edge banding defects. 2. The bonding surface of the glue only exists on one side and the bottom, the bonding area is small, the bonding is not strong, and the edge banding glue is easy to debond. Summary of the invention

[0006] Based on this, the present invention provides a dimming component and a preparation method thereof, a dimming glass, a display device and a vehicle. The dimming component is edge-sealed by an adhesive block and a decorative layer. When the dimming glass is subsequently prepared, the plasticizer in the interlayer can be prevented from reacting with the functional material in the dimming component, thereby preventing the dimming component from failing. At the same time, the problem of uneven glue coating and easy debonding of the edge-sealing glue is solved.

[0007] The technical solution provided by the present invention includes the following:

[0008] A dimming component comprises a first transparent substrate, a first transparent conductive layer, a light control functional layer, a second transparent conductive layer, a second transparent substrate, a bonding block and a decorative layer;

[0009] The first transparent substrate, the first transparent conductive layer, the light control functional layer, the second transparent conductive layer and the second transparent substrate are stacked in sequence, and the dimming component is provided with a bonding hole from the surface of the second transparent substrate through the second transparent substrate, the second transparent conductive layer and the light control functional layer to the first transparent conductive layer;

[0010] The bonding block comprises a filling portion and an extension portion integrally formed with the filling portion, the filling portion fills the bonding hole and is bonded to the hole wall of the bonding hole, and the extension portion is located on the second transparent substrate;

[0011] The decoration layer is arranged on a side of the extension portion away from the second transparent substrate.

[0012] In one embodiment, the aperture of the bonding hole in the light control functional layer segment is greater than or equal to the aperture of the bonding hole in the second transparent substrate segment, and / or the aperture of the bonding hole in the light control functional layer segment is greater than or equal to the aperture of the bonding hole in the second transparent conductive layer segment.

[0013] In one embodiment, a boundary of an orthographic projection of a side wall of the bonding hole in the light control function layer section on the first transparent substrate does not exceed a boundary of an orthographic projection of the extension portion on the first transparent substrate.

[0014] In one embodiment, the decorative layer completely or partially covers the extension portion.

[0015] In one embodiment, the decoration layer has a preset shape, and the decoration layer at least defines a boundary of the dimmable area.

[0016] The present invention also provides a method for preparing a dimming component, comprising the following steps:

[0017] sequentially stacking a first transparent substrate, a first transparent conductive layer, a light control functional layer, a second transparent conductive layer, and a second transparent substrate;

[0018] Remove material downward from the surface of the second transparent substrate to form a bonding hole that penetrates the second transparent substrate, the second transparent conductive layer and the light control functional layer to the first transparent conductive layer;

[0019] Filling the bonding hole with bonding material and allowing the bonding material to overflow the bonding hole;

[0020] The decorative material is placed on the adhesive material, pressed, and cured, so that the adhesive material forms an adhesive block having a filling portion and an extension portion, and the decorative material forms a decorative layer.

[0021] In one embodiment, when forming the bonding hole, the method further includes:

[0022] A solvent is injected into the hole to dissolve a portion of the light control functional layer, so that the aperture of the bonding hole in the light control functional layer segment is greater than or equal to the aperture of the bonding hole in the second transparent substrate segment, and / or the aperture of the bonding hole in the light control functional layer segment is greater than or equal to the aperture of the bonding hole in the second transparent conductive layer segment.

[0023] In one embodiment, the decorative material is selected from metal materials or inorganic non-metal materials.

[0024] In one embodiment, the metal material is selected from at least one of aluminum, iron, copper, silver, gold and zinc;

[0025] The inorganic non-metallic material is selected from ceramics, glass or carbon fiber.

[0026] In one embodiment, the bonding material is selected from epoxy resin adhesive, polyurethane resin adhesive or acrylic resin adhesive.

[0027] A dimming glass comprises a glass substrate and a dimming component arranged on the glass substrate.

[0028] In one of the embodiments, the glass substrate and the dimming component are bonded together by an adhesive layer.

[0029] A display device comprises a fixing mechanism and the dimming glass installed on the fixing structure.

[0030] A vehicle comprises the dimming glass or the display device.

[0031] Compared with the traditional solution, the present invention has the following beneficial effects:

[0032] The present invention uses adhesive blocks and decorative layers to seal the light control function layer of the dimming component. When dimming glass is prepared later, the plasticizer in the laminated adhesive layer can be prevented from reacting with the functional material of the light control function layer to make the dimming component ineffective. In addition, the adhesive blocks of the present invention can be evenly distributed in the edge sealing area, the adhesive blocks have a large bonding area, high bonding strength, are not easy to fall off, and reduce edge sealing defects. Moreover, a decorative layer is provided, which has a strong decorative effect, and its color and type are optional, which is more beautiful; and when dimming glass is prepared later, the decorative layer is laminated to the inside of the glass substrate, isolating the decorative layer from direct contact with the outside world, and there is no need to worry about corrosion, aging and discoloration of the decorative layer. After the dimming component of the present invention is prepared into dimming glass by laminating, after thermal aging at 90°C for 2000 hours, the edge of the dimming area of ​​the dimming glass will not become transparent.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] In the present invention, when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element.

[0060] In the present invention, the optional scope of the terms "and / or", "or / and", and "and / or" used includes any one of two or more related listed items, and also includes any and all combinations of the related listed items, and the any and all combinations include any two related listed items, any more related listed items, or a combination of all related listed items.

[0061] In the present invention, the dimming component can be a multilayer composite structure that adjusts the reflection or transmission properties of the transmitted light, for example, a polymer dispersed liquid crystal (PDLC), a suspended particle device (SPD), a dichroic liquid crystal film (LC), an electrochromic (EC) film, etc.

[0062] Take PLDC as an example. When PLDC is placed in laminated glass to prepare dimming glass, it needs to be bonded to the glass through a glue layer. The liquid crystal polymer in the light control functional layer of PDLC easily reacts with the plasticizer in the glue layer, which will cause the PLDC to fail, and then the dimming glass to fail. The comparison between the failed dimming glass and the good dimming glass is shown in the figure below. Figure 1 As shown, the left side is a failed smart glass, and the edge of the smart glass becomes transparent.

[0063] The edge sealing process can prevent the plasticizer in the glue layer from entering the light control functional layer of PLDC and reacting with the liquid crystal polymer. However, the current edge sealing process generally adopts a half-cut process, cutting out steps, and then using a glue-spraying device to glue this area and then solidify it. Figure 2 As shown, 10 is the first transparent substrate, 11 is the first transparent conductive layer, 12 is the light control functional layer, 13 is the second transparent conductive layer, 14 is the second transparent substrate, and 15 is the edge sealing glue. This treatment has the problems of uneven glue coating and easy debonding of the edge sealing glue.

[0064] like Figure 3 , which is a front cross-sectional view of a dimming component according to an embodiment of the present invention, the dimming component includes a first transparent substrate 21 , a first transparent conductive layer 22 , a light control function layer 23 , a second transparent conductive layer 24 , a second transparent substrate 25 , a bonding block 26 and a decorative layer 27 .

[0065] The first transparent substrate 21 , the first transparent conductive layer 22 , the light control function layer 23 , the second transparent conductive layer 24 and the second transparent substrate 25 are stacked in sequence.

[0066] Optionally, the first transparent substrate 21 and the second transparent substrate 25 include, but are not limited to, PET (polyethylene terephthalate) substrates.

[0067] In this embodiment, the dimming component is PLDC, and the light control function layer contains liquid crystal polymer.

[0068] In this embodiment, the dimming component is provided with a bonding hole extending from the surface of the second transparent substrate 25 through the second transparent substrate 25 , the second transparent conductive layer 24 and the light control function layer 23 to the first transparent conductive layer 22 .

[0069] In this embodiment, the bonding hole penetrates the second transparent substrate 25, the second transparent conductive layer 24 and the light control function layer 23 to the surface of the first transparent conductive layer 22. In other embodiments, the bonding hole may also penetrate into the interior of the first transparent conductive layer 22.

[0070] It can be understood that the hole wall of the bonding hole includes a side wall and a bottom wall, the bottom wall is the first transparent conductive layer 22, and the side wall is composed of the light control functional layer 23, the second transparent conductive layer 24 and the side wall of the second transparent substrate 25. The bonding hole has two side walls and a large bonding area. Moreover, the bonding blocks can be evenly distributed in the bonding hole, which is conducive to firm bonding. The bonding blocks are not easy to debond, reducing edge sealing defects.

[0071] In this embodiment, the diameter of the bonding hole in the light control function layer 23 section is larger than the diameter of the bonding hole in the second transparent substrate 25 section, and larger than the diameter of the bonding hole in the second transparent conductive layer 24 section. Figure 4 As shown, the bonding block 26 is in an I-shape, and includes a filling portion 261 and an extension portion 262 integrally formed with the filling portion 261. The filling portion 261 fills the bonding hole and is bonded to the hole wall of the bonding hole, and the extension portion 262 is located on the second transparent substrate 25. The thickness direction of the dimming component is specified to be the longitudinal direction, and the transverse cross-sectional area occupied by the filling portion 261 of the light control function layer 23 is greater than the transverse cross-sectional area occupied by the second transparent substrate 25, and is greater than the transverse cross-sectional area occupied by the second transparent conductive layer 24.

[0072] In other embodiments, the diameter of the bonding hole in the light control function layer 23 section is equal to the diameter of the bonding hole in the second transparent substrate 25 section, and is equal to the diameter of the bonding hole in the second transparent conductive layer 24 section. Figure 5 As shown in FIG. 1 , the bonding block 36 is T-shaped and includes a filling portion 361 and an extension portion 362 integrally formed with the filling portion 361. The front cross-sectional view of the structure of the dimming assembly including the bonding block 36 is shown in FIG. Figure 6 As shown, the dimming component includes a first transparent substrate 31, a first transparent conductive layer 32, a light control function layer 33, a second transparent conductive layer 34, a second transparent substrate 35, a bonding block 36 and a decorative layer 37. At this time, the transverse cross-sectional area occupied by the filling portion 261 of the light control function layer 33 is equal to the transverse cross-sectional area occupied by the second transparent substrate 35, and is equal to the transverse cross-sectional area occupied by the second transparent conductive layer 34.

[0073] By comparison, it can be seen that the bonding holes in this embodiment have a larger bonding area, a higher bonding strength, and are more conducive to preventing the bonding block from falling off.

[0074] It can also be understood that in other embodiments, the aperture of the bonding hole in the light control function layer segment is greater than or equal to its aperture in the second transparent substrate segment, or the aperture of the bonding hole in the light control function layer segment is greater than or equal to its aperture in the second transparent conductive layer segment.

[0075] In this embodiment, the boundary of the orthographic projection of the side wall of the bonding hole in the light control function layer 23 section on the first transparent substrate 21 does not exceed the boundary of the orthographic projection of the extension portion 262 on the first transparent substrate 21. This arrangement can prevent the filling portion 261 from affecting the pattern display of the dimmable area. It can be understood that the dimmable area is an area that appears transparent or opaque in the on and off states.

[0076] In this embodiment, the decorative layer 27 is arranged on the side of the extension 262 away from the second transparent substrate 25. The decorative layer 27 is provided to facilitate the application of pressure when the adhesive material is cured to form an adhesive block. Moreover, the decorative layer has a strong decorative effect, and its color and type are optional, which is more beautiful. In the subsequent preparation of dimming glass, the decorative layer is laminated to the inside of the glass substrate, isolating the decorative layer from direct contact with the outside world, and there is no need to worry about the corrosion, aging and discoloration of the decorative layer. In addition, by pressing the adhesive material with the decorative layer, there is no risk of poor sealing due to lack of glue; there is also no risk of glass cracking due to excessive glue thickness and height difference.

[0077] Optionally, the decoration layer 27 completely or partially covers the extension portion 262 .

[0078] Optionally, the decorative layer 27 has a preset shape, and the decorative layer 27 at least defines the boundary of the dimmable area. The shape of the decorative layer 27 can be adjusted to flexibly design dimmable areas with different patterns. It can be understood that the decorative layer can be a bright decorative strip.

[0079] It can be understood that the area defined by the decorative layer 27 is the dimmable area, and the area outside the decorative layer is the non-dimmable area. It can be further understood that the non-dimmable area includes the edge sealing area. Generally, the electrode of the dimming component is located in the edge sealing area, which does not affect the dimming of the dimmable area.

[0080] Figure 7 This is a top view of the dimming component of this embodiment. The decorative layer 27 partially covers the extension part. The decorative layer 27 defines the boundary of the dimmable area. The area defined by the decorative layer 27 is the dimmable area. The dimmable area is the area where the light control function layer is not blocked by the extension part. The area outside the area defined by the decorative layer is a non-dimmable area. At this time, the non-dimmable area includes the edge sealing area.

[0081] In this embodiment, the decorative layer 27 is a bright decorative strip in a strip shape. Optionally, the decorative layer 27 is a strip with a thickness of 0.05-0.15 mm and a width of 5-10 mm. This arrangement with a decorative layer can make the pattern more beautiful.

[0082] It can be understood that the area on the extension portion that is not covered with the decorative layer 27 may be covered with or not covered with other layers, and the other layers include but are not limited to PVC (polyvinyl chloride) layers.

[0083] In other embodiments, Figure 8 As shown, the decorative layer 47 completely covers the extension part, and the area defined by the decorative layer 47 is the dimmable area, which is the area where the light control functional layer is located and not blocked by the extension part. The area outside the area defined by the decorative layer is the non-dimmable area, and at this time, the non-dimmable area is the edge sealing area.

[0084] Optionally, in addition to defining the boundaries of the dimmable area, the decorative layer 27 may further divide the dimmable area to present a dimmable area with more diverse patterns.

[0085] The light control function layer is sealed by the bonding block and the decorative layer. The prepared dimming component can be used to prepare dimming glass, which can prevent the plasticizer in the interlayer from reacting with the liquid crystal polymer in the light control function layer to cause the dimming component to fail.

[0086] The present invention also provides a method for preparing the dimming component of the above embodiment, the process is as follows Fig. 9 As shown, the steps are as follows:

[0087] The first transparent substrate 21 , the first transparent conductive layer 22 , the light control function layer 23 , the second transparent conductive layer 24 and the second transparent substrate 25 are stacked in sequence.

[0088] Material is removed downward from the surface of the second transparent substrate 25 to form a hole that penetrates the second transparent substrate 25, the second transparent conductive layer 24 and the light control functional layer 23 to the surface of the first transparent conductive layer 22, and then a solvent is injected to dissolve a portion of the light control functional layer 23 to form a bonding hole.

[0089] Optionally, the removal method includes but is not limited to etching. It can be understood that etching is a technique for removing materials by chemical reaction or physical impact, including cutting, etc. In some embodiments, the second transparent substrate 25 of the self-dimming component is cut at a position where the edge is retracted by 2mm-5mm, and a hole with an aperture of 2m-5mm is cut. Cutting can be performed using a cutting device such as a laser cutter, etc. After cutting, the cut material is cleaned, and solvents such as alcohol and acetone can be used for cleaning and wiping.

[0090] After cleaning, a solvent is injected to dissolve a portion of the light control function layer 23. The solvent is a solvent capable of dissolving the light control function layer 23, including but not limited to a mixed solvent of benzene and acetone. In this embodiment, a mixed solvent of benzene and acetone with a volume ratio of 1:1 is used to dissolve a portion of the light control function layer 23. It can be understood that after the solvent is injected, it is soaked for more than 10 minutes so that the aperture of the bonding hole in the light control function layer 23 section is larger than its aperture in the second transparent substrate 25 section, and larger than its aperture in the second transparent conductive layer 24 section. Then the mixed solvent is discharged and wiped clean with a dust-free cloth.

[0091] In other embodiments, the solvent may not be injected and the light control function layer may not be dissolved, so that the aperture of the bonding hole in the light control function layer section is equal to its aperture in the second transparent substrate section and equal to its aperture in the second transparent conductive layer section.

[0092] It can also be understood that in other embodiments, by removing material and injecting or not injecting solvent, the aperture of the bonding hole in the light-control functional layer segment is greater than or equal to its aperture in the second transparent substrate segment, or the aperture of the bonding hole in the light-control functional layer segment is greater than or equal to its aperture in the second transparent conductive layer segment.

[0093] Filling the bonding hole with bonding material and allowing the bonding material to overflow the bonding hole;

[0094] Optionally, the adhesive material can be filled using a glue gun or an automatic glue dispenser. In addition to filling the adhesive hole, the adhesive material is also made 0.1 mm-0.5 mm higher than the second transparent substrate. The adhesive material includes but is not limited to epoxy resin adhesive, polyurethane resin adhesive or acrylic resin adhesive.

[0095] The decorative material is placed on the adhesive material, pressed, and cured. The adhesive material forms an adhesive block 26 having a filling portion and an extension portion, and the decorative material forms a decorative layer 27 .

[0096] Optionally, the decorative material is a bright decorative material in the form of a strip with a thickness of 0.05-0.15 mm and a width of 5-10 mm. Before the decorative material is placed on the adhesive material, the surface can be cleaned with alcohol or acetone.

[0097] Optionally, the decorative material may completely cover the adhesive material or may partially cover the adhesive material. When the decorative material completely covers the adhesive material, the outer side of the decorative material may be flush with the edge of the dimming component or may extend beyond the edge of the dimming component to completely cover the edge of the dimming component; when the decorative material partially covers the adhesive material, the other part of the adhesive material may be covered or uncovered by other materials (such as PVC material), the decorative material is located on the side of the adhesive material close to the dimmable area, and the other materials may be flush with the edge of the dimming component or extend beyond the edge of the dimming component to completely cover the edge of the dimming component.

[0098] In this embodiment, the decorative material partially covers the adhesive material and is located on a side of the adhesive material close to the dimmable area, and the rest of the adhesive material is covered by the PVC material, which is flush with the edge of the dimming component.

[0099] Apply pressure on the decorative material and the PVC material to flatten the adhesive material that protrudes above the second transparent substrate, place it at room temperature for 1-3 hours, or heat it at 80°C for 15 minutes to solidify it. The adhesive material solidified in the bonding hole forms a filling part, and the adhesive material solidified outside the bonding hole forms an extension part.

[0100] Optionally, the decorative material is selected from metal materials or inorganic non-metal materials.

[0101] Further optionally, the metal material is selected from at least one of aluminum, iron, copper, silver, gold and zinc; and the inorganic non-metallic material is selected from ceramics, glass or carbon fiber.

[0102] The above-mentioned decorative material is resistant to high temperatures and has a dense structure. It is located in the edge sealing area and can completely isolate the plasticizer from entering the liquid crystal through the edge sealing adhesive even at high temperatures, thereby achieving 100% sealing.

[0103] The present invention also provides a dimming glass, comprising a glass substrate and a dimming component arranged on the glass substrate.

[0104] In one embodiment, the glass substrate and the dimming component are bonded together by an adhesive layer.

[0105] In one embodiment, a method for preparing dimming glass, such as Fig.10 As shown, the steps are as follows:

[0106] The first glass 201 is bonded to the dimming component through the first adhesive layer 203 , and the second glass 202 is bonded to the dimming component through the second adhesive layer 204 , so as to obtain the dimming glass.

[0107] The first adhesive layer 203 and the second adhesive layer 204 include but are not limited to EVA (polyethylene-polyvinyl acetate copolymer) adhesive layer, PVB (polyvinyl butyral) adhesive layer, etc.

[0108] In this embodiment, the second adhesive layer 204 is bonded to the second glass 202 on the second transparent substrate 25. After the dimming glass of this embodiment is thermally aged at 90°C for 2000 hours, the edge of the dimming area will not become transparent. Moreover, the dimming component can be placed at any position of the laminated glass, and the dimming area of ​​different shapes can be formed on the glass by changing the preset shape of the decorative layer.

[0109] It can be understood that in other embodiments, the second adhesive layer can be bonded to the second glass on the second transparent substrate and the decoration layer respectively.

[0110] This embodiment further provides a display device, including a fixing mechanism and a dimming glass installed on the fixing structure.

[0111] This embodiment also provides a vehicle, which includes the above-mentioned dimming glass or the above-mentioned display device.

[0112] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0113] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent.
