Detailed Description

In order to make the technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a cross-sectional view of a light control glass according to an embodiment of the present invention, and it should be noted that the light control glass in the embodiment may be applied to windows of high-speed railway, windows of automobiles, curtain walls of buildings, and the like.

As shown in fig. 1, the light control glass includes: the first substrate 110 and the second substrate 350 arranged facing the cassette; and a dimming layer disposed between the first substrate 110 and the second substrate 350; a first conductive layer 130 is formed on the first substrate 110; a first insulating layer 140 is formed on the first conductive layer 130; a heat generating layer 330 is further formed on the second substrate 350; a second insulating layer 320 is formed on the heat generating layer 330. A second conductive layer 310 is formed on the second insulating layer 320.

Specifically, in the present embodiment, the first substrate 110 and the second substrate 350 are disposed in a pair, and the dimming layer is disposed between the first substrate 110 and the second substrate 350, in forming the dimming glass proposed in the present embodiment, the first conductive layer 130 may be formed on the first substrate 110, and the first insulating layer 140 may be formed on the first conductive layer 130 in advance; meanwhile, the heat generating layer 330 is formed on the first and second substrates 350, the second conductive layer 310 is formed on the heat generating layer 330, and finally the first substrate 110 is disposed facing the second substrate 350, and the dimming layer is disposed between the first substrate 110 and the second substrate 350, thereby forming the dimming glass as shown in fig. 1.

In the process of using the light control glass provided by the embodiment, when the temperature of the light control glass is low, the internal temperature of the light control glass in the embodiment can be increased through the heat generating layer 330 formed on the second insulating layer 320, so that the light control glass can normally work at low temperature, the abnormal display is prevented, and the application range of products is further expanded.

In this embodiment, the layer 330 that generates heat can adopt the graphite alkene material to make transparent heating film, wherein transparent heating film's transmissivity is greater than 95%, the performance that generates heat is stable, the principle that the accessible electricity generates heat, come to generate heat layer 330 and energize, so that generate heat layer 330 and heat up, electric heat conversion effect is high, be close to 99%, promptly through less voltage alright quick messenger's self heat-up and heat up, on the manufacture craft, the mode formation that accessible chemical vapor deposition method (CVD) or rendition has the film heating layer 330 of figure, the area of generating heat keeps big such as light adjusting glass's visual area basically, thereby can make light adjusting glass be heated evenly, finally reach visual effect's homogeneity.

Since the first conductive layer 130 and the second conductive layer 310 located at two sides of the dimming layer are usually energized to form a vertical electric field to control liquid crystal in the dimming layer and adjust the light transmittance when dimming the dimming glass in this embodiment, the first conductive layer 130 and the second conductive layer 310 may be specifically indium tin oxide films, and when the temperature of the dimming glass is low, a voltage needs to be applied to the heating layer 330 to heat the heating layer 330, therefore, in an actual manufacturing process, since the first conductive layer 130, the second conductive layer 310 and the heating layer 330 are not located on the same layer, the first conductive layer 130, the second conductive layer 310 and the heating layer 330 need to be respectively electrically connected to a plurality of circuit boards to perform energization operation, so that the overall structure of the device is complex and the manufacturing difficulty is increased.

Therefore, in the present embodiment, the first conductive layer 130 and the second conductive layer 310 can be electrically connected to a circuit board simultaneously for conducting power, so as to simplify the overall structure and reduce the manufacturing difficulty, wherein the specific implementation structure is as shown in fig. 2, the second insulating layer 320 is formed with a via hole 321 through, the projection of the via hole 321 on the second substrate 350 is located outside the projection of the second conductive layer 310 on the second substrate 350, a metal layer 322 electrically connected to the heat generating layer 330 is formed in the via hole 321, the metal layer 322 is electrically connected to a first metal trace 410, the first conductive layer 130 is electrically connected to a second metal trace (since the electrical connection manner between the first conductive layer 130 and the second metal trace is the prior art, the corresponding connection manner is not shown in fig. 2 and 3), as shown in fig. 3, the second conductive layer 310 is electrically connected to a third metal trace 420, that is, in the present embodiment, since the projection of the via hole 321 on the second substrate 350 is located outside the projection of the second conductive layer 310 on the second substrate 350, the metal layer 322 formed in the via hole 321 can be electrically insulated from the second conductive layer 310, and the first metal trace 410 is electrically connected to the metal layer 322, so as to electrically connect the first metal trace 410 and the heat generating layer 330, and in order to further improve the insulating effect between the metal layer 322 and the second conductive layer 310, in the example of fig. 2, a third insulating layer 323 can be formed on the second insulating layer 320, wherein the third insulating layer 323 is located between the second conductive layer 310 and the metal layer 322, wherein the first insulating layer 140, the second insulating layer 320, and the third insulating layer 323 can all use silicon nitride or a resin material, and herein, the heat generating layer 330, the first conductive layer 130, the second conductive layer 310, and the first metal trace 410 are respectively, The second metal trace and the third conductive layer are electrically connected, so that the first metal trace 410, the second metal trace and the third metal trace 420 are electrically connected to a circuit board at the same time, and voltage transmission of each layer can be realized through a single circuit board, so that the overall structure is simple and reliable.

In one implementation, a first constant temperature layer 120 is further formed between the first substrate 110 and the first conductive layer 130, and a second constant temperature layer 340 is further formed between the second substrate 350 and the heat generating layer 330.

Specifically, in an example, the first constant temperature layer 120 and/or the second constant temperature layer 340 may be made of a resin-doped silica aerogel powder material, the transmittance ranges from 80% to 95%, the nano porous space network structure is provided, and thermal convection can be effectively blocked, and in the manufacturing process, a thin film constant temperature layer may be formed on the surfaces of the first substrate 110 and the second substrate 350 by deposition or coating, so that not only the temperature of the dimming layer is increased, but also the indoor environment temperature is regulated, and here, according to the needs of an actual use scene, it may be considered that the constant temperature layer is manufactured only on one side of the dimming glass in the low temperature environment;

in another example, the first thermostatic layer 120 and/or the second thermostatic layer 340 may be replaced by a vacuum layer for heat preservation, and a vacuum environment is used to block heat convection, and meanwhile, the light transmittance of the existing dimming glass is not lost.

In one implementation, the dimming layer includes:

a sealing structure 210;

a dye liquid crystal 220 encapsulated within the sealing structure 210; and

a support post 230 disposed within the sealing structure 210.

In this embodiment, the light control glass mainly uses the dye liquid crystal 220 as a light control layer, wherein the light transmittance is approximately in the range of 30% to 75%, the dark transmittance is in the range of 0.5% to 15%, the support column 230 is preferably made of a black resin material, the dark transmittance can be correspondingly reduced, the height of the support column 230 can be in the range of 4 μm to 30 μm, the transmittance can be correspondingly adjusted, and the sealing structure 210 uses a resin adhesive to perform a complete circle coating to encapsulate the dye liquid crystal 220.

Compared with the prior art, the heating layer 330, the first constant temperature layer 120 and the second constant temperature layer 340 are added to the light control glass in the embodiment, and the total transmittance range of the light control glass is about 76% -91%, specifically, when the light transmittance of the designed light control layer is 33%, the dark transmittance is 1%, the height of the supporting column 230 is 24 μm, and the total transmittance of the added heating layer 330 and constant temperature layer is 80%, the transmittance loss needs to be compensated by optimizing the light control layer, in one example, the height of the supporting column 230 is adjustable, the transmittance level of the light control layer can be conveniently adjusted by adjusting the height of the supporting column 230, according to the test result, when the height of the supporting column 230 is adjusted by 1 μm, the transmittance can correspondingly occur by 5%, so that in order to keep the transmittance levels after the heating layer 330, the first constant temperature layer 120 and the second constant temperature layer 340 are added, the transmittance of the dimming layer needs to be increased by 25%, that is, the height of the supporting post 230 needs to be decreased by 5 μm to 19 μm, and when the high transmittance heating layer 330, the first constant temperature layer 120 and the second constant temperature layer 340 are selected, if the transmittance is 90%, the height of the supporting post 230 needs to be decreased by only about 2.2 μm, so that the adjustment of the existing process can be reduced as much as possible, and for the case of a slightly low transmittance, the adjustment and matching of the process conditions can be performed according to a similar method to achieve the final purpose.

Fig. 4 is a flowchart illustrating a method for manufacturing a light control glass according to another embodiment of the present invention, where as shown in fig. 4, the method includes the following steps:

forming a second conductive layer 310 on the second insulating layer 320;

disposing the first substrate 110 and the second substrate 350 facing each other toward the cassette;

a dimming layer is disposed between the first substrate 110 and the second substrate 350.

Fig. 5 is a block diagram illustrating a structure of a dimming device according to another embodiment of the present invention, where, as shown in fig. 5, the dimming device includes: the invention provides dimming glass, a temperature detection module and a control module.

Specifically, in the embodiment, the control module may be a circuit board, and the control module is electrically connected to the light adjusting glass through the first metal trace 410, the second metal trace and the third metal trace 420, so that the control module outputs voltages to the first metal wire 410, the second metal wire and the third metal wire 420, respectively, the temperature detection module can be a temperature sensor or a thermistor, the temperature detection module can be built in the light-adjusting glass, or can be integrated with the control unit in one device, the temperature sensor is arranged independently of the dimming glass and is used for detecting the temperature of the dimming glass to generate temperature data, the control module compares the temperature data with a preset threshold value, and generating a heating voltage or a dimming voltage according to the comparison result, so that the dimming glass is heated based on the heating voltage and is dimmed based on the dimming voltage.

In one implementation, when the temperature data is less than the preset threshold, the control module generates a heating voltage to enable the dimming glass to be heated based on the heating voltage.

Specifically, when the temperature data is smaller than the preset threshold, it indicates that the temperature of the dimming glass is low in the current state, and may cause an abnormal display during operation, so that the dimming glass needs to be heated, and the temperature of the dimming glass is increased.

In one implementation, when the temperature data is not less than the preset threshold, the temperature control module generates a dimming voltage so that the dimming glass performs dimming based on the dimming voltage.

Specifically, when the temperature data is not less than the preset threshold, it indicates that the dimming glass does not need to be heated in the current state, and the dimming glass can be directly dimmed, where the first conductive layer 130 is electrically connected to the second metal trace, and the second conductive layer 310 is electrically connected to the third metal trace 420, so that the dimming voltage can be input to the first conductive layer 130 and the second conductive layer 310 by the control module through the second metal trace and the third metal trace 420, respectively, so that the first conductive layer 130 and the second conductive layer 310 are electrified to form a vertical electric field, and the dimming layer is controlled to dim.

Fig. 6 is a flowchart illustrating a method for using a dimming device according to a previous embodiment of the present invention, where the method for using the dimming device according to the previous embodiment of the present invention, as shown in fig. 6, includes the following steps:

the temperature detection module detects the temperature of the dimming glass to generate temperature data;

the control module compares the temperature data with a preset threshold value, and generates a heating voltage or a dimming voltage according to the comparison result, so that the dimming glass is heated based on the heating voltage and is dimmed based on the dimming voltage.

In this embodiment, the preset threshold may be set according to the product characteristics and the application field of the light control glass, when the light control glass is used, the temperature detection module detects the temperature of the light control glass in real time to generate temperature data, the control module compares the temperature data with the preset threshold, and then controls the operation of the heat generation layer 330 according to the comparison result, so as to ensure that the light control glass can be normally started at an appropriate temperature when the light control voltage is input to the light control glass, it should be noted that, in this embodiment, the specific value of the preset threshold may be set by a worker, which is not specifically limited in this embodiment, in one example, the preset threshold may be set higher according to the actual application of the light control glass, so as to ensure that there is no delay phenomenon in the low temperature environment, in another example, the preset threshold may be set to be higher than 0 ℃, thereby can avoid the phenomenon of dimming glass fogging, have better visual effect and experience.

First, the dimming glass in this embodiment may artificially preset a preset threshold according to the product characteristics and the use condition of the low-temperature environment, for example: when the low temperature environment is-30 ℃, the preset threshold is set to-10 ℃, and when the temperature detection module detects that the temperature of the dimming glass is reduced to-10 ℃, because the first metal wire 410 is electrically connected with the heating layer 330 through the metal layer 322, the control module inputs a heating voltage to the heating layer 330 through the first metal wire 410, so that the heating layer 330 is rapidly heated based on the heating voltage to ensure that the ambient temperature of the dimming glass can meet the requirement of normal display, and when the temperature detection module detects that the environment of the dimming glass is higher than-10 ℃, the control module does not output the heating voltage any more, the heating layer 330 stops working, at this time, it indicates that the temperature of the dimming glass has reached the suitable temperature for dimming, and because the first conductive layer 130 and the second conductive layer 310 are respectively electrically connected with the second metal wire and the third metal wire 420, therefore, the control module can input a dimming voltage to the first conductive layer 130 and the second conductive layer 310 through the second metal trace and the third metal trace 420, respectively, so as to dim the dimming layer.

It should be understood that the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and it will be obvious to those skilled in the art that other variations or modifications may be made on the basis of the above description, and all embodiments may not be exhaustive, and all obvious variations or modifications may be included within the scope of the present invention.
