Optionally, the hollow region 5 has a thickness of between 4 mm and 20 mm in a direction from the first dimming cell 1 to the second dimming cell 2. Specifically, the thickness of the hollow region 5 includes, but is not limited to, 12 mm.

Alternatively, the orthographic projection of the connection assembly 3 on the second substrate 13 is frame-shaped, and the hollow area 5 is formed in the closed space formed by the second substrate 13, the connection assembly 3 and the fourth substrate 23 so as to contain gas, so that the light control glass device 100 has good sound insulation and heat insulation effects.

In some possible embodiments, the dimming module is combined with a glass substrate to form the dimming glass, and the dimming module itself includes substrate substrates on both sides and a liquid crystal layer in the middle, and if the glass substrate is directly used to replace the thin plate of the dimming module, the liquid crystal layer is disposed between the substrate substrates, so that the substrate substrates can be omitted. Therefore, referring to fig. 1, the second dimming unit 2 further includes: and a fourth substrate 23.

The first substrate 11 and the second substrate 13 are cell-to-cell connected, forming a first liquid crystal cell for accommodating the first liquid crystal layer 121.

The hollow region 5 is formed between the second substrate 13 and the fourth substrate 23.

In the present 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 substrate substrates for preparing the first dimming module 12, the first substrate 11 and the second substrate 13 form a first liquid crystal cell into which the first liquid crystal layer 121 is accommodated.

In the present embodiment, the glass substrate of each dimming cell is directly used as the substrate of the first liquid crystal layer 121, and two substrates are omitted in each dimming cell, thereby reducing the thickness of each dimming cell. Meanwhile, the first substrate 11 and the second substrate 13, or the third substrate 21 and the fourth substrate 23 are connected or packaged in the box connecting process, a preparation process of interlayer lamination is not needed, an adhesive layer is not needed, and the phenomenon of black spots caused by uneven thickness of the adhesive layer due to uneven stress in the interlayer lamination process is eliminated.

Alternatively, the first dimming cell 1 and the second dimming cell 2 have the same structure, and the positions may be interchanged when combining the two dimming cells. However, the orientations of the first liquid crystal layer 121 and the second liquid crystal layer 221 are different, and therefore, the first dimming cell 1 and the second dimming cell 2 need to be aligned during the combination process, and the alignment is kept in a state of having an included angle between the first liquid crystal layer 121 and the second liquid crystal layer 221.

Compared with the sandwich structure of the conventional first dimming unit 1, the embodiment of the application reduces two substrates of about 0.5 mm and 2 bonding layers, and the whole thickness can be reduced by 5 mm to 9 mm after the dimming glass device 100 is combined.

In the present embodiment, the conductive hole 111 of the first substrate 11 and the conductive hole 111 of the second substrate 13 may electrically control the first dimming unit 1 by connecting wires to the outside instead of the flexible circuit board 6 for supplying voltage. The conductive holes 111 of the third substrate 21 and the conductive holes 111 of the fourth substrate 23 may electrically control the second dimming unit 2 by connecting wires to the outside instead of the flexible circuit board 6 supplying the voltage.

In this embodiment, the first dimming module 12 is a complete first dimming liquid crystal cell 122, and the first dimming liquid crystal cell 122 is connected with the first substrate 11 and the second substrate 13 on both sides through adhesive layers, compared with the first dimming unit 1 having two layers of the first dimming liquid crystal cells 122 in the prior art, the first dimming unit 1 provided in this embodiment uses fewer adhesive layers, so that the condition that the adhesive layers are uneven in thickness during the process of forming the first dimming unit 1 by laminating the interlayer sheets is alleviated, and the formation of black spots is reduced. The first dimming liquid crystal cell 122 in this embodiment is smaller in size than the first substrate 11 and the second substrate 13, that is, there is a step difference between the first dimming liquid crystal cell 122 and the first substrate 11 and the second substrate 13, and the first dimming liquid crystal cell is located in the central area of the first substrate 11, the first filling structure 15 can fill a space formed between the first dimming liquid crystal cell 122 and the substrates on both sides due to the step difference, and the first filling structure 15 has a reduced thickness compared with the prior art, so that the condition of uneven thickness of the first filling structure 15 due to uneven stress is reduced, and formation of black spots is further reduced.
