Description

Technical Field

[0001] The present application relates to the technical field of dimming glass, and more specifically, to a dimming glass device and a method for preparing the same. Background Art

[0002] At present, dimming glass devices have been widely used in the fields of construction, transportation, etc. due to their advantages such as fast response speed and low haze. The dimming glass device is usually composed of at least two dimming units, one dimming unit is set to face the light, and the other dimming unit is set to face the light. At least two dimming units are combined to adjust the light.

[0003] Generally, the dimming glass device is divided into two dimming units, and the dimming module set in the dimming unit plays the role of adjusting the light. In order to achieve better energy saving effect and reduce the heat transferred from the light-facing side to the backlight side of the dimming glass device, two layers of dimming modules are usually set in the first dimming unit.

[0004] However, the dimming module needs to be bonded to the substrates on both sides through an adhesive layer. The adhesive layer is fluid and rough at high temperatures. It is easily affected by pressure during the bonding process, resulting in uneven thickness, which affects the uniformity of the thickness of the dimming module.

It should be understood that the implementation methods described below in conjunction with the drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application and do not constitute a limitation on the technical solutions of the embodiments of the present application.

[0085] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0086] The research and development ideas of this application include: In the prior art, two layers of dimming modules are usually set in one dimming unit, and the substrate and the dimming module, as well as the two layers of dimming modules, need to be connected using an adhesive layer, and the interlayer lamination process is carried out in an autoclave to combine the dimming module with the substrate. Therefore, at least three layers of adhesive layers are required in each dimming unit. However, the more adhesive layers are used, the more likely it is that uneven thickness will occur during the interlayer lamination process, resulting in local black spots on the dimming module, which in turn affects the display uniformity.

[0087] The dimming glass device and the preparation method thereof provided in the present application are intended to solve the above technical problems in the prior art.

[0088] The following is a detailed description of the technical solution of the present application and how the technical solution of the present application solves the above technical problems with specific embodiments. It should be noted that the following implementations can refer to, draw on or combine with each other, and the same terms, similar features and similar implementation steps in different implementations will not be described repeatedly.

[0089] Please refer to Figure 1 , Figure 3 and Figure 5 The embodiment of the present application provides a dimming glass device 100, including: a connecting component 3, a first dimming unit 1 and a second dimming unit 2.

[0090] The first dimming unit 1 is located at one end of the connecting component 3, and includes a stacked first substrate 11, a first dimming module 12, and a second substrate 13. The first dimming module 12 includes a first liquid crystal layer 121, and a base substrate located on both sides of the first liquid crystal layer 121, and the base substrate can be a glass substrate or a flexible transparent substrate, and the second substrate 13 is close to the connecting component 3.

[0091] The second dimming unit 2 is located at the other end of the connecting component 3, and includes a stacked second dimming module 22 and a third substrate 21. The second dimming module 22 includes a second liquid crystal layer 221, and a base substrate located on both sides of the second liquid crystal layer 221, and the base substrate can be a glass substrate or a flexible transparent substrate. The second dimming module 22 is close to the connecting component 3.

[0092] In this embodiment, the first dimming unit 1 and the second dimming unit 2 are connected to form a complete dimming glass device 100 through a connecting component 3. The first dimming module 12 and the second dimming module 22 are respectively arranged in the first dimming unit 1 and the second dimming unit 2, which reduces the thickness of the first dimming unit 1, reduces the number of adhesive layers, reduces the influence of the adhesive layer on the uniformity of the thickness of the first dimming module 12, reduces the formation of black spots, and further enhances the display uniformity of the dimming glass device 100. In this embodiment, the orientations of the first liquid crystal layer 121 and the second liquid crystal layer 221 independently arranged in two different dimming units have an angle, and the liquid crystal molecules in the first liquid crystal layer 121 or the second liquid crystal layer 221 can rotate under the action of the electric field to adjust the transmittance of light.

[0093] Optionally, the first liquid crystal layer 121 and the second liquid crystal layer 221 have an angle in their orientations.

[0094] Optionally, the dimming glass device 100 further comprises: a hollow area 5 formed between the first dimming unit 1 and the second dimming unit 2. In this embodiment, the first dimming unit 1 and the second dimming unit 2 are aligned and connected via a connecting component 3, so that a hollow area 5 is formed between the first dimming unit 1 and the second dimming unit 2.

[0095] Optionally, in the direction from the first dimming unit 1 to the second dimming unit 2, the thickness of the hollow area 5 is between 4 mm and 20 mm. Specifically, the thickness of the hollow area 5 includes but is not limited to 12 mm.

[0096] Optionally, the orthographic projection of the connecting component 3 on the second substrate 13 is frame-shaped, and the hollow area 5 is formed in a closed space formed by the second substrate 13, the connecting component 3 and the fourth substrate 23 to accommodate gas, so that the dimming glass device 100 has good sound insulation and heat insulation effects.

[0097] In some possible implementations, the dimming module is combined with a glass substrate to form a dimming glass, and the dimming module itself includes base substrates on both sides and a liquid crystal layer in the middle. If a glass substrate is directly used to replace the thin plate of the dimming module and a liquid crystal layer is set between the base substrates, the base substrate can be omitted. Figure 1 The second dimming unit 2 also includes: a fourth substrate 23.

[0098] The first substrate 11 and the second substrate 13 are connected in a cell-to-cell manner to form a first liquid crystal cell for accommodating the first liquid crystal layer 121 .

[0099] The fourth substrate 23 is connected to the third substrate 21 in a cell-type manner to form a second liquid crystal cell for accommodating the second liquid crystal layer 221 .

[0100] The second substrate 13 is connected to one end of the connecting component 3 , and the fourth substrate 23 is connected to the other end of the connecting component 3 .

[0101] The hollow area 5 is formed between the second substrate 13 and the fourth substrate 23 .

[0102] In this embodiment, the first dimming unit 1 includes a first substrate 11 and a corresponding second substrate 13. The first substrate 11 and the second substrate 13 are used as the base substrates for preparing the first dimming module 12. The first substrate 11 and the second substrate 13 are paired to form a first liquid crystal box, and the first liquid crystal layer 121 is contained in the first liquid crystal box. The second dimming unit 2 includes a third substrate 21 and a corresponding fourth substrate 23. The third substrate 21 and the fourth substrate 23 are used as the base substrates for preparing the second dimming module 22. The third substrate 21 and the fourth substrate 23 are paired to form a second liquid crystal box, and the second liquid crystal layer 221 is contained in the second liquid crystal box. In this embodiment, by directly using the glass substrate of the dimming unit as the substrate of the first liquid crystal layer 121, two substrates are omitted in each dimming unit, thereby reducing the thickness of each dimming unit. At the same time, during the box connection process, the first substrate 11 and the second substrate 13, or the third substrate 21 and the fourth substrate 23 have been connected or packaged, and there is no need to carry out the interlayer preparation process or use the adhesive layer. This eliminates the black spot phenomenon caused by uneven thickness of the adhesive layer due to uneven stress during the interlayer bonding process.

[0103] Optionally, corresponding electrode layers, alignment layers, etc. are provided on one side of the first substrate 11 and one side of the second substrate 13. The first liquid crystal layer 121 is located between the alignment layers corresponding to the first substrate 11 and the second substrate 13, and also includes a sealing glue that encapsulates the entire first dimming unit 1.

[0104] Optionally, corresponding electrode layers, alignment layers, etc. are provided on one side of the third substrate 21 and one side of the fourth substrate 23. The second liquid crystal layer 221 is located between the alignment layers corresponding to the third substrate 21 and the fourth substrate 23, and also includes a frame sealant that encapsulates the entire second dimming unit 2.

[0105] Optionally, the first dimming unit 1 and the second dimming unit 2 have the same structure, and can be interchanged when the two dimming units are combined. However, the first liquid crystal layer 121 and the second liquid crystal layer 221 have different orientations, so during the combination process, the first dimming unit 1 and the second dimming unit 2 need to be aligned to distinguish the front and back, so that the first liquid crystal layer 121 and the second liquid crystal layer 221 maintain an orientation angle.

[0106] Compared with the sandwich structure of the conventional first dimming unit 1 , the embodiment of the present application reduces two substrates of about 0.5 mm and two adhesive layers. After being assembled into the dimming glass device 100 , the overall thickness can be reduced by 5 mm to 9 mm.

[0107] Therefore, for some possible implementations, please refer to Figure 2 The switchable glass device 100 includes a binding area 110 .

[0108] The first substrate 11 , the second substrate 13 , the third substrate 21 and the fourth substrate 23 all have conductive holes 111 located in the binding area 110 .

[0109] The orthographic projections of the conductive holes 111 of the first substrate 11 and the conductive holes 111 of the second substrate 13 on the first substrate 11 are spaced from the orthographic projections of the conductive holes 111 of the third substrate 21 and the conductive holes 111 of the fourth substrate 23 on the first substrate 11 .

[0110] In this embodiment, the conductive holes 111 of the first substrate 11 and the conductive holes 111 of the second substrate 13 can replace the flexible circuit board 6 that provides voltage by connecting wires to the outside, so as to power on and control the first dimming unit 1. The conductive holes 111 of the third substrate 21 and the conductive holes 111 of the fourth substrate 23 can replace the flexible circuit board 6 that provides voltage by connecting wires to the outside, so as to power on and control the second dimming unit 2. In addition, the conductive holes 111 can distinguish the positive and negative directions when the first dimming unit 1 and the second dimming unit 2 are aligned. When aligned, the conductive holes 111 in the first dimming unit 1 and the conductive holes 111 in the second dimming unit 2 are staggered with each other to ensure that the orientation between the first liquid crystal layer 121 and the second liquid crystal layer 221 has an angle.

[0111] Optionally, the conductive hole 111 is used to enable an external power source to provide a voltage to the first dimming unit 1 and / or the second dimming unit 2 .

[0112] Optionally, refer to Figure 2 The arrows in the figure indicate that the pre-tilt angles of the alignment layers on both sides of the first liquid crystal layer 121 are the same and in the same or opposite directions (i.e. Figure 2 The pre-tilt angles of the alignment layers on both sides of the second liquid crystal layer 221 are the same and in the same or opposite directions (i.e. Figure 2 The conductive holes 111 can distinguish the positive and negative directions when the first dimming unit 1 and the second dimming unit 2 are aligned. When aligned, the conductive holes 111 in the first dimming unit 1 and the conductive holes 111 in the second dimming unit 2 are staggered to ensure that the pretilt angles of the alignment layers on both sides of the first liquid crystal layer 121 and the alignment layers on both sides of the second liquid crystal layer 221 have an angle between them.

[0113] Please refer to Figure 3 In some possible implementations, the first dimming module 12 includes: a first dimming liquid crystal box 122 . The first dimming unit 1 also includes: a first adhesive layer 14 , a first filling structure 15 and a second adhesive layer 16 .

[0114] The first adhesive layer 14, the first dimming liquid crystal box 122 and the second adhesive layer 16 are stacked. The first adhesive layer 14 is connected to the central area of ​​one side of the first substrate 11 at a side away from the first dimming liquid crystal box 122, and the second adhesive layer 16 is connected to the second substrate 13 at a side away from the first dimming liquid crystal box 122.

[0115] The first filling structure 15 is disposed on the periphery of the stacked first adhesive layer 14 , the first dimming liquid crystal box 122 and the second adhesive layer 16 . One side of the first filling structure 15 is connected to the edge area of ​​one side of the first substrate 11 , and the other side is connected to the second substrate 13 .

[0116] In the present embodiment, the first dimming module 12 is a complete first dimming liquid crystal box 122, and the first dimming liquid crystal box 122 is connected to the first substrate 11 and the second substrate 13 on both sides through an adhesive layer. Compared with the first dimming unit 1 with two layers of the first dimming liquid crystal box 122 in the prior art, the first dimming unit 1 provided in the present embodiment uses fewer adhesive layers, which reduces the uneven thickness of the adhesive layer that may occur in the process of sandwiching and laminating to form the first dimming unit 1, and reduces the formation of black spots. The size of the first dimming liquid crystal box 122 in the present embodiment is smaller than the first substrate 11 and the second substrate 13, that is, there is a step difference between the first dimming liquid crystal box 122 and the first substrate 11 and the second substrate 13, and it is located in the central area of ​​the first substrate 11. The first filling structure 15 can fill the space formed by the step difference between the first dimming liquid crystal box 122 and the substrates on both sides. The thickness of the first filling structure 15 is reduced compared with the prior art, which reduces the uneven thickness of the first filling structure 15 due to uneven stress, and further reduces the formation of black spots.

[0117] Optionally, the first adhesive layer 14, the second adhesive layer 16 and the first filling structure 15 are made of polyvinyl butyral, which can be used as an adhesive, is fluid at high temperatures and has a high roughness. When the first substrate 11 and the second substrate 13 are sandwiched and laminated to form the first dimming unit 1, uneven thickness is easily generated under pressure.

[0118] Please refer to Figure 3 In some possible implementations, the second dimming module 22 includes: a second dimming liquid crystal box 222 . The second dimming unit 2 also includes: a third adhesive layer 24 .

[0119] The third adhesive layer 24 is located between the third substrate 21 and the second dimming liquid crystal cell 222 .

[0120] The orthographic projections of the second dimming liquid crystal box 222 and the third adhesive layer 24 on the third substrate 21 overlap and are both located in the central area of ​​the third substrate 21. The edge area of ​​the third substrate 21 is connected to the connection component 3.

[0121] The hollow area 5 is formed between the second substrate 13 and the third substrate 21 .

[0122] In this embodiment, the second dimming module 22 is a complete second dimming liquid crystal box 222. The second dimming liquid crystal box 222 is connected to the third substrate 21 on one side thereof through a third adhesive layer 24. The third adhesive layer 24 is consistent in size with the second dimming liquid crystal and is located in the central area of ​​the third substrate 21, which is equivalent to only attaching the second dimming liquid crystal box 222 to one side of the third substrate 21 without the process of interlayer lamination. Therefore, no black spots will be generated. The edge area of ​​the third substrate 21 (i.e., the area without the third adhesive layer 24 and the second dimming liquid crystal box 222) is connected to the connecting component 3, so that the first dimming unit 1 and the second dimming unit 2 are combined to form a complete dimming glass device 100. The hollow area 5 is formed between the second substrate 13 and the third substrate 21, and the second dimming liquid crystal box 222 and the third adhesive layer 24 are located in the hollow area 5.

[0123] Please refer to Figure 4 In some possible implementations, the second dimming module 22 includes: a third dimming liquid crystal box 223 . The second dimming unit 2 also includes: a fourth adhesive layer 25 , a second filling structure 26 , a fifth adhesive layer 27 and a fifth substrate 28 .

[0124] The fourth adhesive layer 25, the third dimming liquid crystal box 223 and the fifth adhesive layer 27 are stacked. The side of the fourth adhesive layer 25 away from the third dimming liquid crystal box 223 is connected to the central area of ​​one side of the third substrate 21, and the side of the fifth adhesive layer 27 away from the third dimming liquid crystal box 223 is connected to the fifth substrate 28.

[0125] The second filling structure 26 is located at the periphery of the stacked fourth adhesive layer 25, the third dimming liquid crystal box 223 and the fifth adhesive layer 27. One side of the second filling structure 26 is connected to the edge area of ​​one side of the third substrate 21, and the other side is connected to the fifth substrate 28. The second substrate 13 and the fifth substrate 28 are connected through the connecting component 3. The hollow area 5 is formed between the second substrate 13 and the fifth substrate 28.

[0126] In this embodiment, the second dimming module 22 is a complete third dimming liquid crystal box 223. The third dimming liquid crystal box 223 is connected to the third substrate 21 and the fifth substrate 28 on both sides thereof through the fourth adhesive layer 25 and the fifth adhesive layer 27 respectively. The third dimming liquid crystal box 223 and the third substrate 21 and the fifth substrate 28 also have a step difference due to different sizes. The second filling structure 26 fills the space formed by the step difference between the third substrate 21 and the fifth substrate 28. The number of adhesive layers is reduced compared with the prior art, which reduces the uneven thickness of the fourth adhesive layer 25, the fifth adhesive layer 27 and the first filling structure 15 due to uneven stress, and further reduces the formation of black spots.

[0127] Similar to the above-mentioned embodiment, the first dimming unit 1 and the second dimming unit 2 can have the same structure, and the pre-tilt angle and direction of the alignment layer are also the same. Therefore, the first dimming unit 1 and the second dimming unit 2 can be prepared at the same time, reducing the preparation cost of the dimming glass device 100. When the two dimming units are combined into a whole, the two dimming units are placed one positive and one negative, so that the pre-tilt angles of the alignment layers between the two dimming units cross each other and form a certain angle, such as 90 degrees, to achieve the adjustment of the light.

[0128] Please refer to Figure 5 In some possible implementations, both the first dimming module 12 and the second dimming module 22 have a mark 112 located in the binding area 110 .

[0129] There is a gap between the orthographic projection of the mark 112 of the first dimming module 12 on the first substrate 11 and the orthographic projection of the mark 112 of the second dimming module 22 on the first substrate 11 .

[0130] In this embodiment, in the complete dimming glass device 100, the mark 112 of the first dimming module 12 and the mark 112 of the second dimming module 22 have been aligned, so the projections on the first substrate 11 are spaced apart. Before forming the complete dimming glass device 100, or before aligning the two dimming units, the structures of the two dimming units and even the orientations of the alignment layers can be consistent, and the positions of the marks 112 are also the same, without distinguishing between the front and back. When the dimming glass device 100 is synthesized, the marks 112 of the two dimming modules are spaced apart if they are placed one front and one back.

[0131] The binding area 110 is connected to the external flexible circuit board 6 to provide a voltage or an electric field to the first dimming module 12 or the second dimming module 22 .

[0132] Optionally, the mark 112 can be an anti-foolproof notch, which is a small semicircular substrate notch on the edge of the first dimming module 12 or the second dimming module 22, located in the binding area 110. The binding area 110 needs to be connected to the flexible circuit board 6 and does not belong to the dimming area. Therefore, the anti-foolproof notch will not affect the overall transmittance.

[0133] Optionally, the dimming glass device 100 further includes: an infrared radiation reflective film 4 , which is disposed on a side of the second substrate 13 away from the first liquid crystal layer 121 and connected to the connecting component 3 .

[0134] In this embodiment, please refer to Figure 6 The first dimming unit 1 is placed on the outdoor side, the second dimming unit 2 is placed on the indoor side, the infrared radiation reflecting film 4 is located between the first dimming unit 1 and the second dimming unit 2, and convection is used to take away part of the heat generated on the glass surface due to the dimming module absorbing solar energy. At the same time, the infrared light entering the room is blocked, effectively reducing the shading coefficient of the dimming glass device 100. Figure 7 A schematic structural diagram of another dimming glass device 100 with an infrared radiation reflecting film 4 is also shown.

[0135] Optionally, refer to Figure 8 and Fig. 9 One side of the infrared radiation reflective film 4 is connected to the second substrate 13, and the other side is connected to the fifth substrate 28 through the connecting component 3. In this embodiment, the transmittance of the dimming glass device 100 can reach 10.2% to 42.7%, the shielding coefficient is 0.223 to 0.348, and the heat transfer coefficient is only 1.36. The transmittance change of this embodiment can refer to the attached figure.

[0136] Optionally, refer to Figure 6-Figure 8The connection component 3 further includes: a first sealant 31 and a spacer strip 32. The two ends of the spacer strip 32 respectively connect the two dimming units through the first sealant 31. The first sealant 31 includes but is not limited to hot melt butyl glue, polyisobutylene glue or comfortable glue strip.

[0137] Optionally, the spacer bars 32 include but are not limited to warm edge spacer bars 32 and cold edge spacer bars 32 , and may be made of organic matter or metal, and the metal includes but is not limited to aluminum.

[0138] Optionally, the spacer bar 32 includes but is not limited to an aluminum frame.

[0139] Optionally, the connection component 3 further includes: a second sealant 33. The second sealant 33 is located between the two dimming units and outside the interconnected first sealant 31, the spacer bar 32 and the second sealant 33. The second sealant 33 includes but is not limited to silicone glue, polyurethane glue or polysulfide glue.

[0140] Optionally, the first dimming unit 1 and the second dimming unit 2 are connected via a connecting component 3, and inside the connecting component 3 is a hollow area 5, which can be filled with a hollow gas, such as an inert gas, air, or a mixture of two or more gases, to achieve sound insulation and heat insulation effects.

[0141] Optionally, the first substrate 11 is used to face outdoors, and the third substrate 21 is used to face indoors.

[0142] Optionally, the first liquid crystal layer 121 includes liquid crystal and dichroic dye molecules mixed with the liquid crystal.

[0143] Optionally, when no voltage is applied to the first dimming module 12, the liquid crystal molecules and the dye molecules are evenly distributed and do not deflect, so that light can pass through and present a bright state. When a voltage is applied to the first dimming module 12, the liquid crystal molecules and the dye molecules are deflected, and the dye molecules absorb light, presenting a dark state.

[0144] Alternatively, the second liquid crystal layer 221 includes liquid crystal and dichroic dye molecules mixed with the liquid crystal.

[0145] Optionally, the step difference between the first dimming liquid crystal box 122 and the first substrate 11 is greater than or equal to the sum of the width of the first sealant 31 and the width of the second sealant 33. In other words, the projection of the first dimming liquid crystal box 122 on the first substrate 11 falls within the projection of the first sealant 31 and the second sealant 33 on the first substrate 11, or is just located at the boundary of the projection of the first sealant 31. This design can ensure that the first dimming liquid crystal box 122 is prevented from being damaged by the pressure of the spacer 32 during the process of sandwiching the first substrate 11, the first dimming module 12 and the second substrate 13.

[0146] Optionally, in the embodiment of the present application, the first substrate 11, the second substrate 13, the third substrate 21, the fourth substrate 23 or the fifth substrate 28 includes but is not limited to tempered glass or laminated glass. The thickness of the tempered glass is mostly about 4-10 mm.

[0147] Optionally, the tempered glass used as each substrate in the embodiment of the present application is 6 mm.

[0156] The structural diagram formed after step S103 is as follows Figure 1 shown.

[0157] In this embodiment, two dimming units can be prepared separately, in any order, and then the two prepared dimming units are aligned and connected via the connecting component 3 .

[0160] Optionally, before step S103 , the method further includes: preparing an insulating layer between the conductive hole 111 of the second substrate 13 and the conductive hole 111 of the fourth substrate 23 to prevent an electrical short circuit between the two dimming units.

[0161] Optionally, before step S103 , the method further includes coating an infrared radiation reflecting film 4 on a side of the second substrate 13 away from the first liquid crystal layer 121 .

[0162] Based on the same inventive concept, the present embodiment provides another method for preparing the dimming glass device 100 provided in the above embodiment. The flow chart of the method is as follows: Fig.13 As shown, including:

[0163] S201: In the central area of ​​one side of the first substrate 11, a first adhesive layer 14, a first dimming liquid crystal box 122 and a second adhesive layer 16 are sequentially arranged, and a first filling structure 15 is arranged in the peripheral area of ​​one side of the first substrate 11. The first dimming liquid crystal box 122 includes a first liquid crystal layer 121. The schematic diagram of the structure formed after step S201 is as follows: Fig.14 shown.

[0164] Optionally, the first adhesive layer 14, the second adhesive layer 16 and the first filling structure 15 are solid and can be stacked on each substrate or the dimming liquid crystal box respectively.

[0165] S202: Press the second substrate 13 and one side of the first substrate 11 provided with the first adhesive layer 14 and the first filling structure 15 to form the first dimming unit 1. The schematic diagram of the structure formed after step S202 is as follows Fig.15 As shown, step S204 is then executed.

[0166] Optionally, pressure may be applied from one side of the first substrate 11 or one side of the second substrate 13 to press the stacked film layer structures to form the first dimming unit 1 .

[0167] Optionally, after step 202 , the method further includes coating an infrared radiation reflecting film 4 on a side of the second substrate 13 away from the first liquid crystal layer 121 .

[0168] S203: A third adhesive layer 24 and a second dimming liquid crystal box 222 are sequentially arranged in the central area of ​​one side of the third substrate 21 to form a second dimming unit 2. The second dimming liquid crystal box 222 includes a second liquid crystal layer 221. The structure formed after step S203 is shown in FIG. Fig.16 shown.

[0169] Optionally, the third adhesive layer 24 is solid and can be directly placed on the central area of ​​the third substrate 21. The stacked film structures are then pressed together to form the second dimming unit 2.

[0170] S204: Align the first dimming unit 1 and the second dimming unit 2 so that the orientation of the first liquid crystal layer 121 and the orientation of the second liquid crystal layer 221 have an angle, and connect the edge area on one side of the third substrate 21 to one end of the connecting component 3, and connect the second substrate 13 to the other end of the connecting component 3. The schematic diagram of the structure formed after step S204 is as follows: Figure 3 shown.

[0171] Optionally, before step S201, the process further includes: preparing a first dimming liquid crystal box 122 and preparing a second dimming liquid crystal box 222. The preparation method of the dimming liquid crystal box is similar to the prior art and will not be described in detail.

[0172] Based on the same inventive concept, the present embodiment also provides another method for preparing the dimming glass device 100 provided in the first aspect above. The flow chart of the method is as follows: Fig.17 As shown, including:

[0173] S301 : A first adhesive layer 14 , a first dimming liquid crystal box 122 , and a second adhesive layer 16 are sequentially disposed in a central area on one side of the first substrate 11 , and a first filling structure 15 is disposed in a peripheral area on one side of the first substrate 11 . The first dimming liquid crystal box 122 includes a first liquid crystal layer 121 .

[0174] S302: Press the second substrate 13 and one side of the first substrate 11 provided with the first adhesive layer 14 and the first filling structure 15 to form the first dimming unit 1. The structure formed after steps S301-S302 is similar to the structure formed after steps S201-S202 in the previous embodiment, which can be referred to. Figure 14-15 , then execute step S305.

[0175] The method for preparing the first dimming unit 1 in this embodiment may be completely consistent with the method for preparing the first dimming unit 1 in the previous embodiment.

[0176] S303: In the central area of ​​one side of the third substrate 21, a fourth adhesive layer 25, a third dimming liquid crystal box 223 and a fifth adhesive layer 27 are sequentially arranged, and a second filling structure 26 is arranged in the peripheral area of ​​one side of the third substrate 21. The third dimming liquid crystal box 223 includes a second liquid crystal layer 221. The schematic diagram of the structure formed after step S303 is as follows: Fig.18 shown.

[0177] S304: The fifth substrate 28 is pressed together with one side of the third substrate 21 provided with the fifth adhesive layer 27 and the second filling structure 26 to form the second dimming unit 2. The structure formed after step S304 is shown in FIG. Fig.19 shown.

[0178] The preparation method of the second dimming unit 2 in the present embodiment can be completely consistent with the preparation method of the first dimming unit 1. The prepared first dimming unit 1 and second dimming unit 2 have the same structure, and there is no need to distinguish between the front and the back in the interlayer bonding stage (forming the first dimming unit 1 or the second dimming unit 2 stage respectively).

[0179] S305: Align the first dimming unit 1 and the second dimming unit 2 so that the orientation of the first liquid crystal layer 121 and the orientation of the second liquid crystal layer 221 have an angle, and connect the second substrate 13 to one end of the connecting component 3, and connect the fifth substrate 28 to the other end of the connecting component 3. The schematic diagram of the structure formed after step S305 is as follows: Figure 4 shown.

[0180] The first dimming unit 1 and the second dimming unit 2 obtained in the embodiment of the present application have the same sandwich structure. It is only necessary to distinguish the front and back according to the mark 112 after adding the infrared radiation reflective film 4 to align the dimming glass device 100. This can reduce the product loss caused by the box orientation problem between the first dimming module 12 and the second dimming module 22 during the stage of separately preparing the first dimming unit 1 and the second dimming unit 2, thereby saving the product preparation cost.

[0181] Optionally, before step S301, the process further includes: preparing a first dimming liquid crystal box 122 and preparing a second dimming liquid crystal box 222. The preparation method of the dimming liquid crystal box is similar to the prior art and will not be described in detail.

[0182] By applying the embodiments of the present application, at least the following beneficial effects can be achieved:

[0183] 1. The first dimming module 12 and the second dimming module 22 are respectively arranged in the first dimming unit 1 and the second dimming unit 2, which reduces the thickness of the first dimming unit 1, reduces the number of adhesive layers, reduces the influence of the adhesive layer on the uniformity of the thickness of the dimming module, reduces the formation of black spots, and thus enhances the display uniformity of the dimming glass device 100. In this embodiment, the orientations of the first liquid crystal layer 121 and the second liquid crystal layer 221 independently arranged in two different dimming units have an angle, and the liquid crystal molecules in the first liquid crystal layer 121 or the second liquid crystal layer 221 can rotate under the action of the electric field to adjust the transmittance of light.

[0184] 2. The glass substrate of the dimming unit is directly used as the substrate of the first liquid crystal layer 121. Two substrates are omitted in each dimming unit, reducing the thickness of each dimming unit. At the same time, the first substrate 11 and the second substrate 13, or the third substrate 21 and the fourth substrate 23 have been connected or packaged in the process of connecting the boxes, and there is no need to perform the preparation process of sandwich lamination, and no need to use an adhesive layer, eliminating the uneven thickness of the adhesive layer caused by uneven stress during the sandwich lamination process, thereby eliminating the black spot phenomenon caused by uneven stress.

[0185] 3. The first dimming unit 1 provided in this embodiment uses fewer adhesive layers, which reduces the uneven thickness of the adhesive layer that may occur during the process of sandwiching and laminating to form the first dimming unit 1, and reduces the formation of black spots. The first dimming liquid crystal box 122 in this embodiment is smaller than the first substrate 11 and the second substrate 13, that is, there is a step difference between the first dimming liquid crystal box 122 and the first substrate 11 and the second substrate 13, and is located in the central area of ​​the first substrate 11. The first filling structure 15 can fill the space formed by the step difference between the first dimming liquid crystal box 122 and the substrates on both sides. The thickness of the first filling structure 15 is reduced compared with the prior art, which reduces the uneven thickness of the first filling structure 15 due to uneven stress, and further reduces the formation of black spots.

[0186] 4. The third adhesive layer 24 is consistent in size with the second dimming liquid crystal and is located in the central area of ​​the third substrate 21, which is equivalent to sticking the second dimming liquid crystal box 222 only on one side of the third substrate 21 without the interlayer lamination process, so no black spots will be generated.

[0187] 5. The first dimming unit 1 and the second dimming unit 2 obtained in the embodiment of the present application have the same sandwich structure. It is only necessary to distinguish the front and back according to the mark 112 after adding the infrared radiation reflective film 4 to align the dimming glass device 100. This can reduce product losses caused by the box orientation problem between the first dimming module 12 and the second dimming module 22 during the stages of separately preparing the first dimming unit 1 and the second dimming unit 2, thereby saving product preparation costs.
