DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0034] In the description of the present application, it should be understood that the words “first” and “second” are used only for the purpose of description, and cannot be understood as indicating or implying relative importance or indicating the number of the indicated technical features. Therefore, the features defined with “first” and “second” can explicitly or implicitly include one or more features. In the description of the present application, the meaning of “multiple” is two or more, unless otherwise specifically limited.

[0035] In the present application, the word “exemplary” is used to mean “serving as an example, instance, or illustration.” Any embodiment described as “exemplary” in the present application is not necessarily to be construed as preferred or advantageous over other embodiments.

[0036] Please refer to Figure 1 and Figure 2The embodiment of the present application provides a dimming glass, which has a display area and a peripheral area, and comprises a first substrate 1, a second substrate 2, a first conductive layer 3 and a second conductive layer 4. The first substrate 1 and the second substrate 2 are oppositely arranged, and in the embodiment, the first substrate 1 is located on the side of the second substrate 2 away from the display side of the dimming glass, that is, the first substrate 1 serves as the lower substrate, and the second substrate 2 serves as the upper substrate, that is, the second substrate 2 is closer to the display side. The first conductive layer 3 is arranged on the side of the first substrate 1 facing the second substrate 2, and the second conductive layer 4 is arranged on the side of the second substrate 2 facing the first substrate 1. The part of the first conductive layer 3 located in the peripheral area is provided with a first through groove 31, so that the peripheral area and the display area of the first conductive layer 3 are separated by the first through groove 31.

[0037] The technical scheme provided by the present application separates the peripheral area and the display area of the first conductive layer 3 by providing the first through groove 31 in the part of the first conductive layer 3 located in the peripheral area. Even if the particulate pollutants adhere to the first conductive layer 3 or the second conductive layer 4, so that the first conductive layer 3 and the second conductive layer 4 are connected, because of the existence of the first through groove 31, the display area of the first conductive layer 3 will not have a short circuit problem, and the problem that the dimming glass is easily short-circuited due to the influence of the humidity and particulate matter in the external environment is effectively improved.

[0038] In some embodiments, the first through groove 31 surrounds the display area, so that the display area and the peripheral area can be completely separated by the first through groove 31, avoiding the problem of incomplete separation of partial areas, leading to leakage current short circuit.

[0039] In some embodiments, please refer to Figure 3 The part of the second conductive layer 4 located in the peripheral area is provided with a second through groove 41, and the second through groove 41 surrounds the display area. By providing the second through groove 41 on the second conductive layer 4, it is further avoided that part of the short circuit current passes through the second conductive layer 4 to the display area of the second conductive layer 4. And the second through groove 41 surrounds the display area, so that the display area of the second conductive layer 4 and the peripheral area are completely separated, further reducing the risk of short circuit of the first conductive layer 3 and the second conductive layer 4 in the display area.

[0040] It should be noted that the formation of the first through groove 31 and the second through groove 41 can be by exposure or by laser engraving, without limitation.

[0041] In some embodiments, the first side of the first through slot 31 is arranged close to the first edge of the first substrate 1, and the second side of the second through slot 41 is arranged close to the second edge of the second substrate 2, and the first edge and the second edge are arranged oppositely. In other words, among the two opposite sides of the first through slot 31, the distance between the first side and the edge of the first substrate 1 closest to the first side is less than the distance between the other side and the first substrate 1 closest to the other side; among the two opposite sides of the second through slot 41, the distance between the second side and the edge of the first substrate 1 closest to the second side is less than the distance between the other side and the first substrate 1 closest to the other side, and the first side and the second side are opposite, so that when it is necessary to expose the first conductive layer 3 or the second conductive layer 4, it is convenient to cut the second substrate 2 or the first substrate 1.

[0042] In some embodiments, referring to Figure 2 and Figure 4 , the first conductive layer 3 is formed with a first discharge group 32, and the first discharge group 32 includes two discharge protrusions 321, one of which is located in the peripheral area and the other is located in the display area, so that the first through slot 31 is located between the two discharge protrusions 321. By arranging the discharge protrusions 321 on both sides of the first through slot 31, the static electricity generated in the display area can be conducted to the discharge protrusion 321 in the peripheral area through the discharge protrusion 321 in the display area, and then conducted to the outside or to the anti-static module through the discharge protrusion 321 in the peripheral area. Correspondingly, a second anti-static module 12 can be arranged in the peripheral area of the first conductive layer for receiving static electricity from the display area and rapidly discharging static electricity to prevent high-voltage static electricity from breaking through the internal circuit of the dimming glass.

[0043] Further, the second conductive layer 4 can also be formed with a second discharge group, and the second discharge group has the same structure and beneficial effects as the first discharge group 32. Correspondingly, a second anti-static module 12 is also arranged in the peripheral area of the second conductive layer 4 for receiving static electricity from the display area and rapidly discharging static electricity to prevent high-voltage static electricity from breaking through the internal circuit of the dimming glass. For the second discharge group, because its structure and beneficial effects are the same as those of the first discharge group 32, they will not be described here again, and the following will mainly introduce the first discharge group 32.

[0044] In some embodiments, referring to Figure 4 , at least one sharp corner is arranged on the side of the discharge protrusion 321 facing the first through slot 31. By using the sharp corner structure, the local electric field strength is sharply increased, far exceeding the breakdown threshold of air, so that the electric charge can be attracted to the air from the sharp corner structure by the electric field, collide with air molecules to generate particles, and ionized air will be formed between the two discharge protrusions 321, thereby forming a low-impedance conductive channel, so that the static electricity in the display area is conducted to the peripheral area through the two discharge protrusions 321, and then the static electricity is actively discharged through the second anti-static module 12.

[0045] It should be noted that in other embodiments, the discharge protrusion 321 can also be provided with multiple sharp corners, and the shape of the discharge protrusion 321 can be jagged, triangular, rectangular, a combination of triangular shapes, etc., without limitation, as long as the discharge protrusion 321 has a sharp corner structure for conducting static electricity.

[0046] Further, the sharp corners of the two discharge protrusions 321 are arranged in pairs to enable the sharp corners of the two discharge protrusions 321 to have the shortest spacing distance, facilitating the conduction of static electricity. The spacing between the two sharp corners ranges from 5um to 20um, avoiding too small or too large distances that affect the formation of the electric field and the conduction of static electricity.

[0047] In some embodiments, the plurality of first discharge groups 32 are arranged at intervals around the first through slot 31, improving the range of static electricity discharge and further reducing the risk of damage to internal circuits due to static electricity. Similarly, the plurality of second discharge groups are arranged at intervals around the second through slot 41, also improving the range of static electricity discharge and further reducing the risk of damage to internal circuits due to static electricity.

[0048] It should be noted that the formation of the discharge protrusion 321 can be by exposure or by laser engraving, without specific limitation.

[0049] In some embodiments, the first substrate 1 is provided with a first anti-static module 11 on the side away from the first conductive layer 3. The display area of the first substrate 1 is provided with a through hole 13, and the through hole 13 is provided with a third conductive layer 9. One end of the third conductive layer 9 is connected to the first conductive layer 3, and the other end extends to the side of the first substrate 1 away from the first conductive layer 3 and is connected to the first anti-static module 11. By connecting the first conductive layer 3 and the first anti-static module 11 using the third conductive layer 9, the high voltage generated by static electricity in the display area can be instantaneously transferred to the first anti-static module 11, thereby completing static electricity discharge and protecting the circuits in the display area.

[0050] It should be noted that the third conductive layer 9 can be formed by filling the through hole 13 with part of the material of the first conductive layer 3 during the formation of the first conductive layer 3, without the need for an additional forming process for the third conductive layer 9.

[0051] It should also be noted that the first anti-static module 11 and the second anti-static module 12 can be transient voltage suppression diodes or multi-layer varistors, which function to discharge static electricity.

[0052] In some embodiments, the light-adjustable glass further comprises a first insulating layer 7, a second insulating layer 8, a support 5, and a light-adjustable layer 6. The first insulating layer 7 is arranged on the side of the first conductive layer 3 facing the second conductive layer 4 and fills the first through slot 31, and the first insulating layer 7 further enhances the insulation effect between the peripheral area and the display area of the first conductive layer 3. The second insulating layer 8 is arranged on the side of the second conductive layer 4 facing the first conductive layer 3, and the second insulating layer 8 can also fill the second through slot 41 to enhance the insulation effect between the peripheral area and the display area of the second conductive layer 4. The support 5 is arranged between the first insulating layer 7 and the second insulating layer 8 and located in the peripheral area, and the support 5 defines a light-adjustable area located in the display area. The support 5 mainly serves to support the first substrate 1 and the second substrate 2, so that there is a certain space between the first substrate 1 and the second substrate 2 to arrange the insulating layer, the conductive layer, and the light-adjustable layer 6 and other structures. The support 5 is a glue frame, and the area defined in the middle of the glue frame is the light-adjustable area, and the light-adjustable layer 6 is arranged in the light-adjustable area. The light-adjustable layer 6 can dynamically adjust the light transmittance through external stimulation (such as electric field, temperature, light, etc.). The light-adjustable layer 6 can be realized by using polymer dispersed liquid crystal or electrochromic and the like to dynamically adjust the light transmittance.

The display device has the structures and advantages of the light-adjustable glass, and details are described in the foregoing embodiments of the light-adjustable glass, which will not be repeated here.

Therefore, it should be emphasized and noted that the “one embodiment” or “one alternative embodiment” mentioned in different places in the present specification does not necessarily refer to the same embodiment.
