AI Technical Summary
Existing smart glass is prone to uneven areas (MURA areas) in the transparent area, resulting in color differences between different locations within the transparent area and affecting color consistency.
By setting non-uniformity receiving cavities in the dimming glass assembly, increasing the thickness of the film layer, or opening gaps at the edge of the film layer, the pressure difference of the dimming functional layer is released, causing liquid crystal molecules to gather in the shielded area, forming a non-uniform area and avoiding color difference.
This effectively avoids obvious color differences in transparent areas and improves the color consistency of glass components.

SUMMARY
[0004] Therefore, it is necessary to provide a glass assembly and a vehicle, so that the transparent area does not have obvious color difference, and the color consistency of the entire glass assembly is better.
[0005] A glass assembly, comprising:
[0006] a first glass layer, a first adhesive film layer, a light-adjustable functional layer, a second adhesive film layer and a second glass layer are sequentially stacked along a first direction, and the first direction is defined along the thickness direction of the glass assembly.
[0007] The glass assembly has a transparent area and a shielding area.
[0008] The glass assembly has a non-uniformity area distributed in the shielding area, and the light transmittance of the non-uniformity area is less than the light transmittance of the transparent area.

[0011] At least part of the unevenness accommodation cavity is a blind hole extending along the first direction, and the blind hole is arranged on at least one of the first adhesive film layer and the second adhesive film layer close to the side of the light-adjusting functional layer.
[0012] In one of the embodiments, the thickness of the first adhesive film layer in the unevenness area is greater than the thickness of the first adhesive film layer in the transparent area; and / or,
[0013] The thickness of the second adhesive film layer in the unevenness area is greater than the thickness of the second adhesive film layer in the transparent area.
[0014] In one of the embodiments, the thickness of the first adhesive film layer gradually increases from the transparent area to at least part of the unevenness area; and / or,
[0015] The thickness of the second adhesive film layer gradually increases from the transparent area to at least part of the unevenness area.
[0016] In one of the embodiments, the projection of the first adhesive film layer along the first direction is a first adhesive film profile line, the projection of the light-adjusting functional layer along the first direction is a light-adjusting functional layer profile line, the distance between at least part of the first adhesive film profile line and the edge of the glass assembly is a, the distance between the light-adjusting functional layer profile line and the edge of the glass assembly is b, and a≥b; and / or,

[0023] The aforementioned glass components and vehicles have transparent areas and obstructed areas with lower light transmittance than the transparent areas. The glass components also have non-uniform areas distributed within the obstructed areas. Typically, the non-uniform areas (MURA areas) are darker than the transparent areas. When these are placed within the obstructed areas, rather than the transparent areas, the obstructed areas themselves have lower light transmittance, thus effectively blocking the non-uniform areas (MURA areas) concentrated within them. This prevents noticeable color differences within the entire transparent area, resulting in better color consistency. Attached Figure Description

DETAILED DESCRIPTION
[0040] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of different ways beyond the specific embodiments described and it is therefore contemplated to cover all such modifications as fall within the scope of the application. It is to be understood that the application is not limited in its application to the details set forth in the description below.
[0041] In the description of the present application, it should be understood that if the terms "center", "length", "width", "thickness", "top", "bottom", "inner", "outer" and the like appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be understood as a limitation on the present application.
[0042] In the description of the present application, if the term "a plurality of" appears, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise explicitly and specifically limited.
[0043] In the present application, unless specifically defined otherwise, if there are terms such as "mount", "connect", "connect", "fix", etc., these terms should be understood in a broad sense. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly defined. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0044] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on another element or there can be a middle element. If an element is considered to be "connected" to another element, it can be directly connected to another element or there can be a middle element.
[0045] Referring to Figure 1 , Figure 3 , Figure 5 and Figure 7 , an embodiment of the present application provides a glass assembly including a first glass layer 100, a first adhesive film layer 200, a light-adjusting functional layer 300, a second adhesive film layer 400 and a second glass layer 500 arranged in sequence along a first direction. The first direction is defined along the thickness direction of the glass assembly. Referring to Figure 2 , Figure 4 , Figure 6 and Figure 8 , the glass assembly has a transparent region 610 and a shielding region 620. The glass assembly has a non-uniform region 621 distributed in the shielding region 620, and the light transmittance of the non-uniform region 621 is less than that of the transparent region 610.
[0046] Specifically, the light-adjusting functional layer 300 is mainly LC (liquid crystal), not limited to PDLC (polymer dispersed liquid crystal), GHLC (guest-host effect type liquid crystal), EC (electrochromic device), SPD (suspended particle device), LED, heat insulation film, color-changing film, light guide film, display film, etc.
[0047] Generally, the light transmittance of the shading area 620 of such dimming glass is less than that of the transparent area 610, i.e., the shading area 620 is a darker area than the transparent area 610. The "non-uniformity area" mentioned in the embodiments of the present application refers to a MURA area, which can be a position of display non-uniformity caused by the brightness adjustment mode; or, the MURA area can be a cloud mura defect. During the pressing process of forming the glass assembly, due to the difference in pressure received by each area of the dimming functional layer 300, the liquid crystal molecules in the dimming functional layer 300 flow from the high-pressure area to the low-pressure area under the action of the pressure difference, and gather in the low-pressure area, forming a MURA area with darker color (i.e., lower light transmittance).
[0048] The above glass assembly has a transparent area 610 and a shading area 620. The glass assembly has a non-uniformity area 621 distributed in the shading area 620, and the color of the non-uniformity area (MURA area) is darker than that of the transparent area 610. When the non-uniformity area (MURA area) is arranged in the shading area 620 instead of the transparent area 610, since the light transmittance of the shading area 620 itself is lower than that of the transparent area 610 in such dimming glass, the shading area 620 can shield the non-uniformity area 621 (MURA area) gathered in the shading area 620 to a certain extent, so that the entire transparent area 610 does not exhibit obvious color difference, and the color consistency of the glass assembly is better.
[0049] In some embodiments, the MURA area is defined as having a light transmittance 10% or more lower than that of the transparent area 610.
[0050] In some embodiments, the shading area 620 is in a completely non-transparent state. Alternatively, in some embodiments, the shading area 620 is in a semi-transparent state with partial light transmittance but lower light transmittance than the MURA area.
[0051] Referring to Figure 1 , Figure 3 , Figure 5 and Figure 7 , in some embodiments, the first glass layer 100 has a first ink layer 110 formed by printing ink thereon, and similarly, the second glass layer 500 has a second ink layer 510 formed by printing ink thereon. The first ink layer 110 and the second ink layer 510 are positionally coincident and both are non-transparent, so that the glass assembly forms a shading area 620 in this range. In other embodiments, the first ink layer 110 can be formed by printing ink only on the first glass layer 100, or the second ink layer 510 can be formed by printing ink only on the second glass layer 500.
[0052] Referring to Figure 1 , Figure 2 , Figure 6 and Figure 8In some embodiments, the shielding region 620 is arranged at least partially around the transparent region 610.
[0053] Specifically, the transparent region 610 is located at the center of the glass assembly, and the shielding region 620 is arranged outside the transparent region 610. The first glass layer 100 is printed with the first ink layer 110 in a ring shape around the edge, and the second glass layer 500 is printed with the second ink layer 510 in a ring shape around the edge. The shielding region 620 in a ring shape is formed on the edge of the glass assembly by shielding of the first ink layer 110 and the second ink layer 510, and the transparent region 610 is formed at the center of the glass assembly.
[0054] Of course, in other embodiments, the first ink layer 110 and the second ink layer 510 can also be printed at other positions to arrange the transparent region 610 and the shielding region 620 in other ways. For example, the first ink layer 110 is printed at the center of the first glass layer 100, and the second ink layer 510 is printed at the center of the second glass layer 500. Then, the transparent region 610 will be arranged outside the shielding region 620.
[0055] Referring to Figures 1 to 4 In some embodiments, the first adhesive film layer 200 is provided with a non-uniformity accommodation cavity 210 at a position corresponding to the non-uniformity area 621.
[0056] Specifically, the shape of the non-uniformity accommodation cavity 210 is not limited, and the cross-sectional shape thereof can be any shape such as a circle, a square, an ellipse, etc. The size of the non-uniformity accommodation cavity 210 can also be set as needed. By opening the non-uniformity accommodation cavity 210 at the position on the first adhesive film layer 200 corresponding to the non-uniformity area 621, pressure is released, so that the pressure of the light-adjusting functional layer 300 at the non-uniformity accommodation cavity 210 is smaller. Thus, the liquid crystal molecules in the light-adjusting functional layer 300 flow from the transparent region 610 to the non-uniformity accommodation cavity 210 under the action of the pressure difference, and finally gather in the shielding region 620. The non-transparent shielding region 620 can shield the non-uniformity area 621 gathered in the shielding region 620, so that the entire glass assembly does not exhibit obvious color difference, and the color consistency is better.
[0057] Referring to Figures 1 to 4 Similarly, in some embodiments, the second adhesive film layer 400 is provided with a non-uniformity accommodation cavity 210 at a position corresponding to the non-uniformity area 621.
[0058] Referring to Figures 1 to 4Similarly, in some embodiments, the first adhesive film layer 200 and the second adhesive film layer 400 are both provided with a non-uniformity accommodation cavity 210 corresponding to the position of the non-uniformity area 621. In this way, the pressure release can be performed from both sides of the light-adjusting functional layer 300, so that the pressure of the light-adjusting functional layer 300 at the non-uniformity accommodation cavity 210 is smaller, the guiding effect on the liquid crystal molecule flow is more obvious, and the non-uniformity area 621 is more likely to gather in the shielding area 620.
[0059] Further, when the first adhesive film layer 200 and the second adhesive film layer 400 are both provided with the non-uniformity accommodation cavity 210, the positions of the non-uniformity accommodation cavities 210 provided on the two can coincide or be staggered. When the positions of the non-uniformity accommodation cavities 210 provided on the two coincide, an overlapping non-uniformity area 621 will be formed, and when the positions of the non-uniformity accommodation cavities 210 provided on the two are staggered, a non-uniformity area 621 will be formed at the position corresponding to the non-uniformity accommodation cavity 210 of each of the two.
[0060] Referring to Figure 2 and Figure 4 Further, the non-uniformity accommodation cavity 210 is provided with a plurality of non-uniformity accommodation cavities 210, and in some embodiments, the distance between adjacent non-uniformity accommodation cavities 210 is s, and 15mm≤s≤300mm. It can be understood that if the hole distance is too large, the pressure reduction effect is not obvious, and if the hole distance is too small, the processing difficulty is too large. When the above distance range is met, a relatively obvious pressure reduction effect can be obtained, and the processing difficulty is relatively low.
[0061] Referring to Figure 2 and Figure 4 In some embodiments, the cross-sectional shape of the non-uniformity accommodation cavity 210 is circular, and the diameter of the non-uniformity accommodation cavity 210 is D, and 1mm≤D≤50mm. It has been found through experiments that the improvement effect is not obvious when the diameter is too large or too small. When the above diameter range is met, a relatively obvious pressure reduction effect can be obtained.
[0062] Referring to Figures 1 to 2 In some embodiments, at least part of the non-uniformity accommodation cavities 210 are through holes 211 extending in the first direction, and the first adhesive film layer 200 is provided with the through holes 211. By providing the through holes 211, the pressure release at this position can be performed to a greater extent, so that the pressure of the light-adjusting functional layer 300 at the non-uniformity accommodation cavity 210 is smaller, the guiding effect on the liquid crystal molecule flow is more obvious, and the non-uniformity area 621 is more likely to gather in the shielding area 620.
[0063] Similarly, in some embodiments, the second adhesive film layer 400 is provided with the through holes 211.
[0064] Similarly, in some embodiments, the first adhesive film layer 200 and the second adhesive film layer 400 are both provided with through holes 211. The through holes 211 provided on the two can coincide or be staggered. When the through holes 211 provided on the two coincide, an overlapping non-uniformity area 621 will be formed together, and when the through holes 211 provided on the two are staggered, non-uniformity areas 621 will be formed respectively at the positions corresponding to the through holes 211 of the two.
[0065] Referring to Figures 3 to 4 In some embodiments, at least part of the non-uniformity accommodation cavities 210 are blind holes 212 extending along the first direction, and the first adhesive film layer 200 is provided with blind holes 212 near the side close to the light modulation functional layer 300.
[0066] Specifically, the depth of the blind hole 212 is smaller than the thickness of the first adhesive film layer 200, and the first adhesive film layer 200 is not penetrated. By opening the blind hole 212, pressure release can also be performed, so that the pressure of the light modulation functional layer 300 at the blind hole 212 is smaller.
[0067] Similarly, in some embodiments, the second adhesive film layer 400 is provided with blind holes 212 near the side close to the light modulation functional layer 300.
[0068] Similarly, in some embodiments, the first adhesive film layer 200 is provided with blind holes 212 near the side close to the light modulation functional layer 300, and the second adhesive film layer 400 is provided with blind holes 212 near the side close to the light modulation functional layer 300. The blind holes 212 provided on the two can coincide or be staggered. When the blind holes 212 provided on the two coincide, an overlapping non-uniformity area 621 will be formed together, and when the blind holes 212 provided on the two are staggered, non-uniformity areas 621 will be formed respectively at the positions corresponding to the blind holes 212 of the two.
[0069] In some embodiments, part of the non-uniformity accommodation cavities 210 are the aforementioned through holes 211, and part of the non-uniformity accommodation cavities 210 are the aforementioned blind holes 212.
[0070] Referring to Figures 1 to 4 In some embodiments, a plurality of first adhesive film layers 200 are provided between the first glass layer 100 and the light modulation functional layer 300 and stacked along the first direction, and a plurality of second adhesive film layers 400 are provided between the second glass layer 500 and the light modulation functional layer 300 and stacked along the first direction. Among the plurality of first adhesive film layers 200 and the plurality of second adhesive film layers 400, the first adhesive film layer 200 close to the light modulation functional layer 300 and / or the second adhesive film layer 400 close to the light modulation functional layer 300 are provided with non-uniformity accommodation cavities 210 at positions corresponding to the non-uniformity area 621.
[0071] When the first adhesive film layer 200 and the second adhesive film layer 400 are provided with multiple layers, the unevenness accommodation cavity 210 is provided on the first adhesive film layer 200 close to the light-adjusting functional layer 300 and / or the second adhesive film layer 400 close to the light-adjusting functional layer 300, which can make the pressure release effect caused by the unevenness accommodation cavity 210 act more directly on the light-adjusting functional layer 300, so that the pressure release effect of the light-adjusting functional layer 300 at the unevenness accommodation cavity 210 is more obvious, the guiding effect of the liquid crystal molecule flow is more obvious, and the unevenness area 621 is more likely to gather in the shielding area 620.
[0072] Preferably, in the foregoing embodiments, the minimum distance between the projection profile of the unevenness accommodation cavity 210 along the first direction and the boundary line of the transparent area 610 is not less than 5 mm. Making the unevenness accommodation cavity 210 as far as possible from the transparent area 610 can reduce the probability of the liquid crystal molecule gathering in the transparent area 610, and further ensure that the unevenness area 621 does not appear in the transparent area 610.
[0073] Referring to Figures 5 to 6 In some embodiments, the thickness of the first adhesive film layer 200 at the unevenness area 621 is greater than the thickness of the first adhesive film layer 200 at the transparent area 610.
[0074] Specifically, by increasing the thickness of the first adhesive film layer 200 at the unevenness area 621, the extrusion force of the first glass layer 100 and the second glass layer 500 on the light-adjusting functional layer 300 is better buffered, so that the extrusion of the light-adjusting functional layer 300 at this position is weakened, and thus the pressure of the light-adjusting functional layer 300 at this position is smaller. Therefore, the thickness can be increased as needed in the shielding area 620, so that the liquid crystal molecules flow from the transparent area 610 with greater pressure to the area with smaller thickness, and finally gather in the shielding area 620. The non-transparent shielding area 620 can shield the unevenness area 621 gathered in the shielding area 620, so that the entire glass assembly does not exhibit obvious color difference, and the color consistency is better.
[0075] Similarly, in some embodiments, the thickness of the second adhesive film layer 400 at the unevenness area 621 is greater than the thickness of the second adhesive film layer 400 at the transparent area 610.
[0076] Similarly, in some embodiments, the thickness of the first adhesive film layer 200 and the second adhesive film layer 400 at the unevenness area 621 is greater than the thickness of the first adhesive film layer 200 and the second adhesive film layer 400 at the transparent area 610. In this way, the pressure release of the light-adjusting functional layer 300 from both sides can make the pressure of the light-adjusting functional layer 300 at the position with increased thickness smaller, the guiding effect of the liquid crystal molecule flow is more obvious, and the unevenness area 621 is more likely to gather in the shielding area 620.
[0077] Further, when the thickness of the first adhesive film layer 200 and the second adhesive film layer 400 in the non-uniformity region 621 is greater than the thickness of the first adhesive film layer 200 and the second adhesive film layer 400 in the transparent region 610, the position of the first adhesive film layer 200 where the thickness increases can coincide with the position of the second adhesive film layer 400 where the thickness increases, or can be staggered. When the positions of the first adhesive film layer 200 and the second adhesive film layer 400 where the thickness increases coincide, the overlapping non-uniformity region 621 is formed. When the positions of the first adhesive film layer 200 and the second adhesive film layer 400 where the thickness increases are staggered, the non-uniformity region 621 is formed at the position where the thickness of the first adhesive film layer 200 and the second adhesive film layer 400 increases, respectively.
[0078] Referring to Figures 5 to 6 In some embodiments, the thickness of the first adhesive film layer 200 gradually increases from the transparent region 610 to the non-uniformity region 621 at least in part.
[0079] Specifically, the thickness of the first adhesive film layer 200 continuously changes in at least part of the region, so that the first adhesive film layer 200 has an inclined surface along the first direction towards and / or away from the surface of the light control functional layer 300 in at least part of the region, and the shape is more regular and the pressure change is more uniform.
[0080] Similarly, in some embodiments, the thickness of the second adhesive film layer 400 gradually increases from the transparent region 610 to the non-uniformity region 621 at least in part.
[0081] Similarly, in some embodiments, the thickness of the first adhesive film layer 200 and the second adhesive film layer 400 gradually increases from the transparent region 610 to the non-uniformity region 621 at least in part.
[0082] In some embodiments, the difference between the maximum thickness and the minimum thickness of the first adhesive film layer 200 and / or the second adhesive film layer 400 ranges from 0.01 mm to 0.5 mm.
[0083] Referring to Figures 5 to 6 In some embodiments, a plurality of first adhesive film layers 200 are arranged along the first direction between the first glass layer 100 and the light control functional layer 300, and a plurality of second adhesive film layers 400 are arranged along the first direction between the second glass layer 500 and the light control functional layer 300. In the plurality of first adhesive film layers 200 and the plurality of second adhesive film layers 400, the position of the first adhesive film layer 200 and / or the second adhesive film layer 400 corresponding to the non-uniformity region 621 near the light control functional layer 300 is configured to have a thickness greater than the transparent region 610.
[0084] When the first adhesive film layer 200 and the second adhesive film layer 400 are provided with multiple layers, the thickness increase is performed on the first adhesive film layer 200 close to the light-adjusting functional layer 300 and / or the second adhesive film layer 400 close to the light-adjusting functional layer 300, which can make the pressure release effect caused by the thickness increase act more directly on the light-adjusting functional layer 300, so that the light-adjusting functional layer 300 has more obvious pressure release effect at the thickness increase position, and the liquid crystal molecules flow more obviously, and the non-uniformity area 621 is more likely to gather in the shielding area 620.
[0085] Referring to Figures 7 to 8 In some embodiments, the profile of the projection of the first adhesive film layer 200 along the first direction is a first adhesive film profile 220, the profile of the projection of the light-adjusting functional layer 300 along the first direction is a light-adjusting functional layer profile 310, the distance between the first adhesive film profile 220 and the edge of the glass assembly at least in part is a, and the distance between the light-adjusting functional layer profile 310 and the edge of the glass assembly is b, a≥b.
[0086] Specifically, by opening the notch 230 at the edge of the first adhesive film layer 200 at least in part, the first adhesive film profile 220 at least in part is located inside the light-adjusting functional layer profile 310, so that a>b. Of course, a can also be equal to b, in which case the light-adjusting functional layer profile 310 and the first adhesive film profile 220 coincide. Opening the notch 230 can have a similar effect to the non-uniformity accommodation cavity 210 in the foregoing embodiments. The notch 230 can release pressure, so that the pressure of the light-adjusting functional layer 300 at the notch 230 is smaller, so that the liquid crystal molecules in the light-adjusting functional layer 300 flow from the transparent area 610 to the notch 230 under the action of the pressure difference, and finally gather in the shielding area 620. The non-transparent shielding area 620 can shield the non-uniformity area 621 gathered in the shielding area 620, so that the entire glass assembly does not exhibit obvious color difference, and the color consistency is better.
[0087] In Figures 7 to 8 In the embodiment shown in FIG. 6, b>0, that is, the light-adjusting functional layer profile 310 and the profile of the entire glass assembly do not coincide, and there is a distance b between them. In other embodiments, for example, Figures 11 to 12 In the embodiment shown in FIG. 7, b=0, that is, the light-adjusting functional layer profile 310 and the profile of the entire glass assembly coincide.
[0088] Referring to Figures 9 to 10Similarly, in some embodiments, the profile of the projection of the second adhesive film layer 400 along the first direction is a second adhesive film profile 410, the profile of the projection of the light control functional layer 300 along the first direction is a light control functional layer profile 310, the distance between at least some positions on the second adhesive film profile 410 and the edge of the glass assembly is a, and the distance between the light control functional layer profile 310 and the edge of the glass assembly is b, where a≥b.
[0089] Specifically, by opening the notch 230 at at least some positions of the edge of the second adhesive film layer 400, at least some positions on the second adhesive film profile 410 are located inside the light control functional layer profile 310, so that a>b. Of course, a can also be equal to b, in which case the light control functional layer profile 310 and the second adhesive film profile 410 coincide.
[0090] Similarly, Figures 9 to 10 The embodiments shown can also refer to Figures 11 to 12 The embodiments shown, the light control functional layer profile 310 and the profile of the entire glass assembly coincide, i.e., b=0.
[0091] Similarly, in some embodiments, the profile of the projection of the first adhesive film layer 200 along the first direction is a first adhesive film profile 220, the profile of the projection of the second adhesive film layer 400 along the first direction is a second adhesive film profile 410, the profile of the projection of the light control functional layer 300 along the first direction is a light control functional layer profile 310, and at least some positions on the first adhesive film profile 220 and the second adhesive film profile 410 are located inside the light control functional layer profile 310.
[0092] Further, when the first adhesive film layer 200 and the second adhesive film layer 400 are both provided with notches 230, the positions of the notches 230 provided on the two layers can coincide or be staggered, i.e., the first adhesive film profile 220 and the second adhesive film profile 410 can coincide or be staggered. When the positions of the notches 230 provided on the two layers coincide (i.e., the first adhesive film profile 220 and the second adhesive film profile 410 coincide), an overlapping non-uniformity region 621 will be formed, and when the positions of the notches 230 provided on the two layers are staggered (i.e., the first adhesive film profile 220 and the second adhesive film profile 410 are staggered), a non-uniformity region 621 will be formed at the corresponding positions of the notches 230 on the two layers, respectively.
[0093] Referring to Figures 7 to 10 In some embodiments, the area enclosed by the first adhesive film profile 220 is located within the area enclosed by the light control functional layer profile 310, and / or the area enclosed by the second adhesive film profile 410 is located within the area enclosed by the light control functional layer profile 310.
[0094] Specifically, by setting the notch 230 on the edge of the first adhesive film layer 200 and / or the second adhesive film layer 400, the first adhesive film contour line 220 and / or the second adhesive film contour line 410 are all located inside the light control function layer contour line 310. In this way, the non-uniformity area 621 will be formed on the edge of the glass assembly.
[0095] Referring to Figures 7 to 10 In some embodiments, a plurality of first adhesive film layers 200 are arranged along the first direction between the first glass layer 100 and the light control function layer 300, and a plurality of second adhesive film layers 400 are arranged along the first direction between the second glass layer 500 and the light control function layer 300. Among the plurality of first adhesive film layers 200 and the plurality of second adhesive film layers 400, the first adhesive film layer 200 close to the light control function layer 300 and / or the second adhesive film layer 400 close to the light control function layer 300 are provided with a notch 230 corresponding to the position of the non-uniformity area 621.
[0096] When the first adhesive film layer 200 and the second adhesive film layer 400 are provided with a plurality of layers, the notch 230 provided on the first adhesive film layer 200 close to the light control function layer 300 and / or the second adhesive film layer 400 close to the light control function layer 300 can make the pressure release effect caused by the notch 230 more directly act on the light control function layer 300, so that the light control function layer 300 has more obvious pressure release effect at the notch 230, the guiding effect on the liquid crystal molecule flow is more obvious, and the non-uniformity area 621 is more easily gathered in the shielding area 620.
[0097] In the above-mentioned embodiments of setting the notch 230, preferably, the distance between the contour line of the first adhesive film layer 200 and / or the second adhesive film layer 400 projected along the first direction and the boundary line of the transparent area 610 is not less than 5 mm. In this way, the position of the notch 230 can be as far away from the transparent area 610 as possible, so as to reduce the probability of the liquid crystal molecule gathering in the transparent area 610, and further ensure that the non-uniformity area 621 will not appear in the transparent area 610.
[0098] Referring to Figure 2 , Figure 6 With Figure 8 In some embodiments, the distance between the edge line of the non-uniformity area 621 close to the center of the glass assembly and the edge line of the shielding area 620 close to the center of the glass assembly is w, and w≥10 mm.
[0099] As mentioned above, the non-uniformity area 621 is located in the shielding area 620, and in this embodiment, the non-uniformity area 621 is located away from the transparent area 610 in the shielding area 620, that is, the distance between the non-uniformity area 621 and the transparent area 610 is as far as possible, so as to reduce the probability of liquid crystal molecules gathering in the transparent area 610, and further ensure that the non-uniformity area 621 does not appear in the transparent area 610.
[0100] As mentioned above, the transparent area 610 is located at the center of the glass assembly, and the shielding area 620 is located outside the transparent area 610, that is, the shielding area 620 is located at the edge of the glass assembly. The glass assembly is rectangular, and no matter which way of setting the non-uniformity accommodation cavity 210, or increasing the thickness, or setting the notch 230 is used to form the non-uniformity area 621, the non-uniformity area 621 can be formed only on one side edge of the glass assembly, or simultaneously formed on adjacent edges, or simultaneously formed on opposite edges, or simultaneously formed on four side edges.
[0101] Referring to Figure 13 With Figure 14 In some embodiments, the projection of the light modulation functional layer 300 along the first direction is located within the projection range of the first glass layer 100 and the second glass layer 500 along the first direction. And the outer side of the light modulation functional layer 300 is surrounded by a circle of the filling film 700, and the projection profile of the filling film 700 along the first direction coincides with the projection profile of the first glass layer 100 and the second glass layer 500 along the first direction.
[0102] Specifically, the size of the light modulation functional layer 300 is smaller than the size of the first glass layer 100 and the second glass layer 500, and by setting the filling film 700, the thickness difference of the edge area of the light modulation functional layer 300 caused by the size difference can be compensated, and defects such as bubbles and cracks are not easy to be caused. The material of the filling film 700 is the same as that of the first adhesive film layer 200 and the second adhesive film layer 400, which is PVB material. The electrodes of the light modulation functional layer 300 are communicatively connected with the controller 800 through the cable 900. The controller 800 can control the arrangement form of the liquid crystal molecules in the light modulation functional layer 300.
[0103] Further, in some embodiments, the thickness of the first glass layer 100 and the second glass layer 500 is 2.1 mm. The thickness of the first adhesive film layer 200 and the second adhesive film layer 400 is 0.76 mm. A circular through hole 211 is formed on the first adhesive film layer 200 and / or the second adhesive film layer 400 away from the edge position of the electrode of the light modulation functional layer 300, and the hole diameter of the through hole 211 is 6 mm, and the corresponding w is 12 mm (that is, the distance between the inner side edge of the through hole 211 and the inner side edge of the shielding area 620). The light modulation functional layer 300 selects a GHLC flexible light modulation functional layer, and the thickness of the light modulation functional layer 300 is 0.38 mm. The thickness of the filling film 700 is 0.38 mm.
