[0091] Optionally, the thickness of the first adhesive layer 15 is equal to the sum of the thicknesses of the first sub-intermediate layer 161 and the light modulation layer 31.

[0092] Preferably, the thickness of the first sub-intermediate layer 161 is 0.76 mm, the thickness of the light modulation layer 31 is 0.6 mm, and the thickness of the first adhesive layer 15 is 1.36 mm.

[0093] And / or, the low-transmission polymer layer 20 is disposed in the same layer as the second sub-intermediate layer 162.

[0094] Optionally, the thickness of the low-transmission polymer layer 20 is equal to the thickness of the second sub-intermediate layer 162.

[0095] Preferably, the thickness of the low-transmission polymer layer 20 is 0.38 mm.

[0096] Therefore, by limiting the positional relationship of the first bonding layer 15, the first sub-intermediate layer 161, the light modulation layer 31, the low-transmission polymer layer 20, and the second sub-intermediate layer 162, the present embodiment not only facilitates the assembly of the light modulation assembly 1, reduces the difficulty of manufacturing the light modulation assembly 1, but also improves the thickness uniformity of the light modulation assembly 1, thereby improving the optical and mechanical properties of the light modulation assembly 1.

[0097] Further, part of the low-transmission polymer layer 20 and part of the light modulation layer 31 have an overlapping area 17 arranged in an overlapping manner, and the overlapping area 17 is arranged in the non-information collection area 112.

[0098] The low-transmission polymer layer 20 adjacent to the non-information collection area 112 extends to the non-information collection area 112 and is arranged in an overlapping manner with part of the light modulation layer 31.

[0099] Therefore, by limiting the positional relationship of the low-transmission polymer layer 20 and the light modulation layer 31, the present embodiment can shield the edge of the light modulation layer 31, further improve the appearance effect of the boundary between the information collection area 111 and the non-information collection area 112, and further improve the user experience.

[0100] Specifically, the light modulation layer 31 comprises a conductive structure, and the conductive structure is arranged in the overlapping area 17.

[0101] The conductive structure comprises electrodes, connectors, and the like. The orthogonal projection of the conductive structure on the low-transmission polymer layer 20 is located in the overlapping area 17, or in other words, the low-transmission polymer layer 20 shields the conductive structure.

[0102] Therefore, by making the low-transmission polymer layer 20 shield the conductive structure, the present embodiment avoids the user's visual discomfort caused by metal reflection, further improves the appearance effect of the non-information collection area 112, and further improves the user experience.

[0103] And / or, in the stacking direction perpendicular to the glass substrate 10, the width of the overlapping area 17 is 10 mm to 15 mm, and specific examples can be 10 mm, or 11 mm, or 12 mm, or 13 mm, or 14 mm, or 15 mm, etc. Preferably, the width of the overlapping area 17 is 10 mm.

[0104] Therefore, by limiting the width of the overlapping area 17 to be as small as possible, the present embodiment controls the newly generated color difference appearance of the overlapping area 17 to be as narrow as possible, thereby improving the appearance effect of the light modulation assembly 1.

[0105] Further, the photoelectric functional layer 30 comprises the light modulation layer 31.

[0106] The distance between the light-adjusting layer 31 and the edge of the glass substrate 10 is 5-7 mm, for example, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, etc.

[0107] The embodiment limits the distance between the light-adjusting layer 31 and the edge of the glass substrate 10 to reserve the tolerance in the manufacturing process, thereby ensuring the aesthetic appearance of the boundary of the light-adjusting layer 31.

[0108] The distance between the light-adjusting layer 31 and the edge of the light-transmitting area 11 is ≤10 mm, for example, 10 mm, 9 mm, 8 mm, 7 mm, 6 mm, 5 mm, 4 mm, 3 mm, 2 mm, 1 mm, etc.

[0109] The embodiment limits the distance between the light-adjusting layer 31 and the edge of the light-transmitting area 11 to control the gap between the light-adjusting layer 31 and the shielding area 12 as small as possible, thereby improving the appearance effect of the junction of the light-adjusting layer 31 and the shielding area 12 and the user experience.

[0110] In another embodiment, the photoelectric functional layer 30 includes a reflective layer 32, which includes a first reflective layer 321 and / or a second reflective layer 322. The first reflective layer 321 is arranged between the first glass plate 13 and the second bonding layer 16, and the second reflective layer 322 is arranged on the side of the second glass plate 14 away from the first glass plate 13.

[0111] For example, the first reflective layer 321 is arranged between the first glass plate 13 and the second bonding layer 16, in other words, on the second surface.

[0112] For another example, the second reflective layer 322 is arranged on the side of the second glass plate 14 away from the first glass plate 13, in other words, on the fourth surface.

[0113] Optionally, the first reflective layer 321 is a silver-containing coating, and the second reflective layer 322 is a low-emissivity film.

[0114] In an embodiment, the photoelectric functional layer 30 includes a light-adjusting layer 31, and the visible light transmittance TL1 of the light-adjusting assembly 1 in the non-information collection area 112 is ≤2%, for example, 2%, 1.8%, 1.6%, 1.4%, 1.2%, 1%, 0.8%, 0.6%, 0.4%, 0.2%, etc.

[0115] Optionally, the lowest visible light transmittance TL1 of the light-adjusting assembly 1 in the non-information collection area 112 is ≥0.1%, for example, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, etc. 1min≤2%. Preferably, the light modulation assembly 1 has a minimum visible light transmittance TL 1min 1%~2%. Further preferably, the light modulation assembly 1 has a minimum visible light transmittance TL 1min 0.5%~1%. Further preferably, the light modulation assembly 1 has a minimum visible light transmittance TL 1min 0.1%~0.5%.

[0116] And / or, the photoelectric functional layer 30 comprises a light modulation layer 31, the light modulation assembly 1 has a total solar transmittance TTS1 in the non-information collection area 112, and the light modulation assembly 1 satisfies: 5%≤TTS1≤30%, which can be specifically exemplified as 5%, or 7.5%, or 10%, or 12.5%, or 15%, or 17.5%, or 20%, or 22.5%, or 25%, or 27.5%, or 30%, etc.

[0117] Therefore, the present embodiment sets the photoelectric functional layer 30 in the non-information collection area 112 to optimize the heat insulation performance of the vehicle and the visual experience, thereby improving the user experience.

[0118] In another embodiment, the photoelectric functional layer 30 comprises a light modulation layer 31, the light modulation assembly 1 has a visible light transmittance TL2≤2% in the information collection area 111, which can be specifically exemplified as 2%, or 1.8%, or 1.6%, or 1.4%, or 1.2%, or 1%, or 0.8%, or 0.6%, or 0.4%, or 0.2%, etc.

[0119] And / or, the photoelectric functional layer 30 comprises a light modulation layer 31, the light modulation assembly 1 has a total solar transmittance TTS2 in the information collection area 111, and the light modulation assembly 1 satisfies: 20%≤TTS2≤30%, which can be specifically exemplified as 20%, or 21%, or 22%, or 23%, or 24%, or 25%, or 26%, or 27%, or 28%, or 29%, or 30%, etc.

[0120] Therefore, the present embodiment sets the low-transmission polymer layer 20 in the information collection area 111, which not only enables high signal transmittance and optimizes the heat insulation performance of the vehicle, but also cooperates with the photoelectric functional layer 30 to optimize the appearance effect of the boundary between the information collection area 111 and the non-information collection area 112, thereby improving the user experience.

[0121] In an embodiment, the light control assembly 1 has a total solar transmittance TTS1 in the non-information collection area 112 and a total solar transmittance TTS2 in the information collection area 111, and the absolute value of the difference between TTS1 and TTS2 is less than or equal to 20%, for example, 20%, or 18%, or 16%, or 14%, or 12%, or 10%, or 8%, or 6%, or 4%, or 2%, etc.

[0122] Therefore, by limiting the absolute value of the difference between TTS1 and TTS2, the present embodiment avoids obvious differences in the heat insulation effect of the information collection area 111 and the non-information collection area 112, and avoids affecting the uniformity of the heat insulation of the light control assembly 1. In addition, this setting is not limited to light control function products.

[0123] In another embodiment, the light control assembly 1 has a minimum visible light transmittance TL 1min in the non-information collection area 112 and a minimum visible light transmittance TL 2min in the information collection area 111, and the absolute value of the difference between TL 1min and TL 2min is less than or equal to 0.5%, for example, 0.5%, or 0.45%, or 0.4%, or 0.35%, or 0.3%, or 0.25%, or 0.2%, or 0.15%, or 0.1%, or 0.05%, etc.

[0124] Therefore, by limiting the absolute value of the difference between TL 1min and TL 2min , the present embodiment avoids obvious differences in the light transmittance effect of the information collection area 111 and the non-information collection area 112, and avoids affecting the uniformity of the light transmittance of the light control assembly 1. In addition, this setting is not limited to light control function products.

[0125] In yet another embodiment, in the light control assembly 1, the transmission color difference ΔE between the non-information collection area 112 and the information collection area 111 is less than or equal to 2, for example, 2, or 1.8, or 1.6, or 1.4, or 1.2, or 1, or 0.8, or 0.6, or 0.4, or 0.2, etc.

[0126] The transmission color difference refers to the color deviation of the non-information collection area 112 and the information collection area 111 when light passes through the light control assembly 1.

[0127] Therefore, by limiting the transmission color difference ΔE, the present embodiment avoids obvious color difference between the two windows, and avoids affecting the color uniformity of the light control assembly 1. In addition, this setting is not limited to light control function products.
