Description

Technical Field

[0001] This application relates to the field of glass technology, and in particular to a light-emitting glass component and a vehicle. Background Technology

[0002] As automobiles evolve towards greater comfort and intelligence, consumers are demanding increasingly personalized exterior designs. For example, ambient lighting is becoming more widely used in interior spaces, and the application of external illuminated decorations is also increasing. While car windows occupy a significant portion of the vehicle's surface, their current appearance is primarily characterized by a transparent center and black ink printing around the edges, failing to offer many visual highlights or integrate a wider range of optoelectronic functions.

[0003] In related technologies, to add more colors to car window glass, some products incorporate different colored light-emitting devices inside the glass, such as LED beads or chips, surface light sources, fluorescent light sources, or other colored films such as red PET. Specifically, the car window glass is made into a laminated glass consisting of two pieces of glass bonded together with a polymer. These light-emitting devices and colored films are integrated into the ink-printed area of ​​the laminated car window glass. People outside the car can see the light source emitting light or the reflection of the colored film through the outer glass, perceiving the various colors on the glass.

[0004] However, black ink is used to mask the edges of glass where it meets the car body or other special areas requiring shading. Therefore, its development focuses on continuously reducing the light transmittance of black ink to improve its masking effect. If black ink is used for overall screen printing, it severely obstructs the light-emitting devices and color film materials inside the glass. The transmittance of ink for visible light is generally below 0.1%, making the color film material beneath the ink difficult for the human eye to see. Even strong light emitted from the light-emitting devices beneath the ink (such as from a powerful flashlight) is only perceived as a hazy light after being masked and diffused by the ink, resulting in a poor appearance and failing to achieve a decorative effect. Intentionally reducing the masking effect of the ink can lead to an overall grayish appearance, and printing defects and patterns becoming clearly visible under transmitted light. Summary of the Invention

[0005] Therefore, it is necessary to overcome the shortcomings of the existing technology and provide a light-emitting glass component and vehicle that allows light to pass through smoothly when the light source is working, while improving the consistency of appearance when the light source is not emitting light.

[0019] In one embodiment, the light-emitting glass assembly further includes a third adhesive layer disposed between the first adhesive layer and the light-emitting element.

[0020] In one embodiment, the light-emitting glass assembly further includes an intermediate film material disposed between the shielding portion and the light-emitting element; the intermediate film material includes a color film material and / or a functional film material.

In addition, when the light-emitting element is in the working state, the light from the light-emitting element can pass through the shielding part and the perforated hole and be emitted outward, thus being observed.

[0044] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0045] In related technologies, a feasible way to achieve light transmission is to create a perforated area in the ink-printed area of ​​the outer glass pane, corresponding to the position of the light-emitting device or the light-emitting intermediate film. However, the inventors discovered that there is a significant color difference between the ink-printed area and the perforated area, which can easily disrupt the overall consistency of the window's appearance. Furthermore, within the same model series, higher-spec models may have a black-edge illuminated feature, while lower-spec models may omit this feature, but consistency in window appearance is often desired between high-spec and low-spec models. Therefore, finding a way to create a perforated area in the ink-printed area of ​​the laminated glass while avoiding the perforation causing a decline in the appearance of the ink-printed area has become a technical challenge.

[0046] For the reasons mentioned above, this application provides a light-emitting glass component and a vehicle that allows light to pass through smoothly when the light source is working, while improving the uniformity of the appearance when the light source is not emitting light.

[0047] It should be noted that in the following embodiments, the appearance of the polymer adhesive material before and after lamination with the inner and outer glass sheets differs significantly. Before lamination, the polymer adhesive material typically has very high haze. Only after lamination can the polymer adhesive material change from a highly hazy state to a transparent state. Therefore, the transmittance of the polymer adhesive material mentioned in this embodiment refers to the transmittance of the polymer adhesive material itself after lamination. Furthermore, when the human eye observes the colors of the ink-printed and hollowed-out areas, it does so through the outer glass sheet. That is, the perceived color is the color exhibited by the outer glass sheet after it has been combined with the ink or polymer adhesive material and reflected external light. Therefore, the color referenced when selecting the polymer adhesive material is also the color exhibited by the polymer adhesive material after lamination with the inner and outer glass sheets and reflected external light. Unless specifically stated otherwise, the colors mentioned below refer to the colors before lamination, and also to the colors exhibited by the polymer adhesive material in the ink area, hollowed-out area, or transparent area after lamination with the same type of window glass and reflected external light.

[0048] See Figures 1 to 4According to any embodiment of this application, a light-emitting glass assembly is provided, comprising: a first glass plate 10, a first light-blocking layer 20, a second glass plate 30, a second light-blocking layer 40, a light-emitting element 51, and a shielding portion 61. The first glass plate 10 faces the external environment and has a first surface 11 and a second surface 12 disposed opposite to each other. The first light-blocking layer 20 is disposed on the second surface 12, specifically, for example, located in the peripheral area of ​​the second surface 12, thereby forming a black edge area. The first light-blocking layer 20 has a perforation 21. The second glass plate 30 faces the internal environment and has a third surface 31 and a fourth surface 32 disposed opposite to each other. The third surface 31 is disposed opposite to the second surface 12. Specifically, the second light-blocking layer 40 is disposed on the third surface 31 or the fourth surface 32 and is positioned corresponding to the first light-blocking layer 20. The light-emitting element 51 is disposed between the first glass plate 10 and the second glass plate 30, and the light-emitting element 51 is positioned corresponding to the perforation 21. The shielding part 61 is positioned corresponding to the cutout hole 21, and the shielding part 61 is connected between the light-emitting element and the first glass plate 10. Specifically, along the direction perpendicular to the first surface 11, the shielding part 61 can completely cover the cutout hole 21. The visible light transmittance of the shielding part 61 is 2% to 50%, the absolute value of the deviation between the a value of the shielding part 61 and the a value of the first light blocking layer 20 is set within 0.5, the absolute value of the deviation between the b value of the shielding part 61 and the b value of the first light blocking layer 20 is set within 0.5, and the absolute value of the deviation between the L value of the shielding part 61 and the L value of the first light blocking layer 20 is set within 2.5.

[0049] It should be noted that luminescent glass components include, but are not limited to, applications on vehicles or building curtain walls. This embodiment specifically uses an application on a vehicle as an example for further explanation. The external environment refers to the exterior of the vehicle, and the internal environment refers to the interior of the vehicle.

[0050] It should be noted that the positional correspondence setting refers to the fact that, along the thickness direction of the first glass plate 10, that is, in the direction perpendicular to the first surface 11, the projections of the two components on the first surface 11 at least partially overlap, specifically, for example, completely overlap, or for example, the projection of one completely covers the projection of the other.

[0051] The first light-blocking layer 20 has a visible light transmittance of less than or equal to 5%, more preferably less than or equal to 3%, even more preferably less than or equal to 1%, or even less than or equal to 0.1%, or essentially 0%, meaning it is opaque to visible light. The first light-blocking layer 20 is a dark-colored PVB, a dark-colored printed layer, or a dark-colored polymer film. The second light-blocking layer 40 is made of a similar material and can also be a dark-colored printed layer or a dark-colored polymer film consistent with the first light-blocking layer 20.

[0052] The dark printing layer can be black or brown ceramic ink or ultraviolet ink, which is printed on the second surface 12, the third surface 31 or the fourth surface 32 through processes such as screen printing or inkjet printing.

[0053] In addition, dark polymer films can be bulk-colored polymer films, such as adding coloring components during the manufacturing process of polymer films to obtain black or brown PVB, PET, PVC, etc.; or polymer films with surface-printed pigments, such as printing black or brown pigments on the surface of polymer films.

[0054] In some embodiments, the shielding part 61 is made of a polymer adhesive material with a certain color. By appropriately and flexibly adjusting and setting the depth of its color according to actual needs, the absolute values ​​of the deviations of the a value and b value of the shielding part 61 from the a value and b value of the first light blocking layer 20 are respectively set to within 0.5, and the absolute value of the deviation of the L value of the shielding part 61 from the L value of the first light blocking layer 20 is set to within 2.5.

[0055] In some embodiments, the first light-blocking layer 20 is made of dark-colored PVB. The first light-blocking layer 20 is on the same layer as the shielding portion 61. Specifically, the shielding portion 61 fills the perforation 21.

[0056] In some embodiments, the light-emitting glass assembly further includes a first adhesive layer 60. The first adhesive layer 60 is disposed between the light-emitting element 51 and the first light-blocking layer 20. The first adhesive layer 60 and the shielding portion 61 are, for example, disposed on the same layer. Thus, the shielding portion 61 and the first light-blocking layer 20 are disposed on different layers, and the area of ​​the shielding portion 61 can be designed to be larger compared to the arrangement where the shielding portion 61 and the first light-blocking layer 20 are disposed on the same layer.

[0057] It should be noted that the first adhesive layer 60 can be made of the same material as the shielding part 61, or it can be made of a high transmittance (transmittance > 50%) polymer adhesive material, and there is no limitation here.

[0058] The aforementioned luminescent glass assembly, because the shielding part 61 can completely cover the perforated hole 21, has a visible light transmittance of 2% to 50%, and the absolute value of the deviation between the a value of the shielding part 61 and the a value of the first light blocking layer 20 is set within 0.5, the absolute value of the deviation between the b value of the shielding part 61 and the b value of the first light blocking layer 20 is set within 0.5, and the absolute value of the deviation between the L value of the shielding part 61 and the L value of the first light blocking layer 20 is set within 2.5, can maximize the compensation for the color difference between the perforated hole 21 area and the first light blocking layer 20, so that when the light-emitting element 51 is in the off state, it is not easy to find the perforated hole 21 in the first light blocking layer 20 when observing the first glass plate 10 from a certain distance (e.g., >60cm); in addition, when the light-emitting element 51 is in the working state, the light of the light-emitting element 51 can pass through the shielding part 61 and the perforated hole 21 and be emitted outward, thus being observed.

[0059] It should be noted that, through extensive experiments, it has been found that the shielding part 61 is made of a polymer adhesive material with a certain color and is in contact with the first glass plate 10. This layer of polymer adhesive material with a certain color has a certain shielding effect on the light-emitting element 51, color / functional film material, or other polymer adhesive materials of various colors on the side away from the first glass plate 10. Therefore, the color difference between the area of ​​the first light blocking layer 20 and the perforation 21 on the first glass plate 10 is not significantly related to the color and transmittance of the other polymer adhesive material layers other than the first adhesive layer 60. Furthermore, in this embodiment, there are no restrictions on the polymer adhesive material between the light-emitting element 51 and the second glass plate 30; both colored polymer adhesive materials and high transmittance (transmittance > 50%) polymer adhesive materials can be used.

[0060] In some embodiments, the light-emitting element 51 and related components that provide current to the light-emitting element 51, such as pads, wires, FPC or PCB, should be made as black as possible or hidden under other black components, so that when the light-emitting element 51 is in the off state and the first glass plate 10 is observed from a certain distance (e.g., >60cm), the cutout 21 and internal components of the first light blocking layer 20 are not easily visible.

[0061] In some embodiments, the light-emitting element 51 includes, but is not limited to, an LED light (such as...). Figures 1 to 3 Any light source shown), surface light source (such as...) Figure 4 (as shown), fluorescent light source or other colored film materials such as red PET, etc.

[0062] In some embodiments, the specific shape of the perforated hole 21 can be flexibly adjusted and set according to actual needs. It can be a symmetrical shape or an asymmetrical shape, and is not limited here. It includes, but is not limited to, regular shapes such as circular holes, elliptical holes, and polygonal holes, as well as other irregular shapes. Among them, polygonal holes include, but are not limited to, triangular holes, rectangular holes, and pentagonal holes.

[0063] Please see Figure 1 or Figure 2 In one embodiment, taking the outline shape of the hole edge of the hollow hole 21 as a centrally symmetrical figure as an example, the distance between two relatively opposite points on the edge of the hollow hole 21 that pass through the center of the hollow hole 21 and have the smallest distance is set as D, and the distance D ≤ 15mm, specifically such as 15mm, 12mm, 10mm, 8mm, 6mm, 3mm, 1mm, etc.

[0064] In one embodiment, when the cutout 21 is set as a circular hole, the spacing D refers to the diameter of the circular hole. The spacing D is set to ≤15mm. The spacing D is not too large, which would increase the color difference with the black edge area. When the light-emitting element 51 is in the off state, the cutout 21 set in the first light blocking layer 20 is not easily noticed when the first glass plate 10 is observed from a certain distance (e.g., >60cm).

[0065] In one embodiment, when the cutout hole 21 is set as an elliptical hole, the spacing D refers to the length of the minor axis of the elliptical hole. The spacing D is set to ≤15mm. The spacing D is not too large, which would increase the color difference with the black edge area. When the light-emitting element 51 is in the off state, it is not easy to find the cutout hole 21 set in the first light blocking layer 20 when the first glass plate 10 is observed from a certain distance (e.g., >60cm).

[0066] In one embodiment, when the cutout 21 is set as a rectangular hole, the spacing D refers to the width of the rectangular hole. The spacing D is set to ≤15mm. The spacing D is not too large, which would increase the color difference with the black edge area. When the light-emitting element 51 is in the off state, the cutout 21 set in the first light blocking layer 20 is not easily noticed when the first glass plate 10 is observed from a certain distance (e.g., >60cm).

[0067] Please refer to Tables 1 and 2 below. These tables are based on a large amount of experimental data and show the deviations of the spacing D, the Lab value of the shielding part 61 from the Lab value of the first light blocking layer 40, the transmittance of the shielding part 61, and the corresponding various observation effects.

[0068] Table 1

[0069]

[0070] Table 2

[0071]

[0072] In some embodiments, the spacing D ≤ 3mm, specifically, for example, 3mm, 2.5mm, 2mm, 1.5mm, 1mm, 0.5mm, etc. Thus, the area of ​​the cutout 21 is relatively small, and the reflected color of the cutout 21 area is the combined color displayed by the materials of the shielding portion 61 to the second light-blocking layer 40 under the influence of ambient light. Experiments have shown that in a color system expressed in Lab values, it is not necessarily better for the Lab value of the shielding portion 61 to be as close as possible to the Lab value of the first light-blocking layer 20. When the shielding part 61 uses a low-transmittance polymer adhesive material with a darker color, although the Lab value after lamination is closest to the Lab value of the first light-blocking layer 20 (the absolute values ​​of the deviations of the a and b values ​​are within 0.5, the L value of the shielding part 61 is less than the L value of the first light-blocking layer 20, and the transmittance is less than 35%), the human eye can still perceive a significant color difference between the perforated hole 21 area and the first light-blocking layer 20, with the perforated hole 21 area being darker than the black edge area. When the shielding part 61 uses a high-transmittance (transmittance > 50%) polymer adhesive material, the Lab value after lamination differs significantly from the Lab value of the first light-blocking layer 20, and the human eye also perceives a significant color difference between the perforated hole 21 area and the first light-blocking layer 20, with the perforated hole 21 area being darker than the black edge area. When the shielding part 61 is laminated with a light-colored polymer adhesive material, the a and b values ​​in the Lab value are very close to those of the first light-blocking layer 20 (the absolute values ​​of the deviations of the a and b values ​​are within 0.5, the L value of the shielding part 61 is 0 to 2.5 greater than the L value of the first light-blocking layer 20, and the transmittance of the shielding part 61 is between 35% and 50%). In practice, the color difference between the perforated hole 21 area and the black edge area is small to the human eye. From a certain distance (e.g., >60cm), it is almost impossible to distinguish between the perforated hole 21 area and the black edge area. However, upon close observation (e.g., less than 60cm), it can still be observed that the color of the perforated hole 21 area is darker than that of the black edge area. Therefore, in this embodiment, the spacing D ≤ 3mm, and the shielding part 61 is selected with a light-colored polymer adhesive material whose a and b values ​​are close to or consistent with those of the ink-printed area, and whose L value is 0 to 2.5 greater than that of the ink-printed area. Actual testing showed that the transmittance of the shielding part 61 was between 35% and 50%.

[0073] Since it is difficult to form a tight and good bond directly between the light-emitting element 51 and the glass plate, the light-emitting element 51 is disposed inside the polymer adhesive layer of the laminated glass. To achieve this, in this embodiment, the light-emitting glass assembly further includes a second adhesive layer 70, which is disposed between the light-emitting element 51 and the second glass plate 30. Thus, the light-emitting element 51 is disposed between the first adhesive layer 60 and the second adhesive layer 70, connected to the first glass plate 10 through the first adhesive layer 60, and connected to the second glass plate 30 through the second adhesive layer 70. Of course, the second adhesive layer 70 can be omitted, and the light-emitting element 51 can be embedded inside the first adhesive layer 60, or the light-emitting element 51 can be directly and tightly abutted against the second glass plate 30 and encapsulated and fixed in the first adhesive layer 60.

[0074] Extensive experiments have confirmed that if the spacing D ≤ 3 mm, and the shielding part 61 is connected to the first glass plate 10 using an appropriate polymer adhesive material (the absolute values ​​of a and b values ​​are within 0.5 of the a and b values ​​of the black edge area, the absolute value of the L value is within 2.5 of the L value of the black edge area, and the transmittance is between 35% and 50%), then the color difference between the black edge area and the hollow hole 21 area on the first glass plate 10 will not be significantly related to the color and transmittance of the remaining polymer adhesive material layers below this layer, and can to a certain extent cover the color difference between the lower light-emitting element 51 and the black edge area.

[0075] In some embodiments, the spacing D is 3mm to 15mm, the area size of the cutout 21 is relatively large, and the color of the shielding part 61 itself can be clearly displayed. At this time, in order to make the color in the area of ​​the cutout 21 as close as possible to the color of the black edge area, the shielding part 61 uses a darker color and a low transmittance polymer adhesive material (the absolute value of the deviation between the a value and b value of the shielding part 61 and the a value and b value of the black edge area is controlled within 0.5, the absolute value of the deviation between the L value of the shielding part 61 and the L value of the black edge area is within 2.5, and the transmittance is 2% to 35%), so that the color of the shielding part 61 itself is as close as possible to the black edge area. At the same time, the low transmittance polymer adhesive material can also reduce the role of the reflection color of the bottom second light blocking layer 40 in the overall reflection color of the cutout area.

[0076] In some embodiments, due to certain alignment errors before and after the lamination process, in order to avoid partial obstruction of the light emitted by the light-emitting element 51 by the ink printing area outside the hollow hole 21 area, causing differences in brightness between different light-emitting elements 51, the size of the hollow hole 21 should be larger than the size of the light-emitting element 51.

[0077] Please see Figures 1 to 3In any embodiment, the first orthographic projection of the perforation 21 on the surface of the first glass plate 10 completely covers the second orthographic projection of the light-emitting element 51 on the surface of the first glass plate 10, and the distance S1 between the outline of the first orthographic projection and the outline of the second orthographic projection is set to 0.5mm to 5mm. Specifically, the distance S1 is set to 0.5mm, 1mm, 2mm, 3mm, 4mm, 4.5mm, 5mm, etc. In this way, the light emitted by the light-emitting element 51 can pass through the area of ​​the perforation 21, and the first light blocking layer 20 can prevent the light from the light-emitting element 51 from being blocked.

[0078] Please see Figure 3 In one embodiment, the first adhesive layer 60 includes a visible light transmitting portion 62 connected to the shielding portion 61. The shielding portion 61 is disposed corresponding to the peripheral area of ​​the first glass plate 10, and the visible light transmitting portion 62 is disposed corresponding to the central area of ​​the first glass plate 10. The visible light transmittance of the visible light transmitting portion 62 is, for example, higher than that of the shielding portion 61. Specifically, the visible light transmittance of the visible light transmitting portion 62 includes, but is not limited to, greater than or equal to 70%, more preferably greater than or equal to 80%, or even greater than or equal to 90%. In other words, the visible light transmitting portion 62 uses a lighter-colored or high-transmittance (transmittance > 50%) polymer adhesive material. Thus, the visible light transmitting portion 62 can help improve the transmittance of the transparent area of ​​the light-emitting glass assembly, while the shielding portion 61 can help achieve a consistent appearance color in the black edge area.

[0079] Of course, in some embodiments, the visible light transmittance of the visible light transmitting portion 62 may be lower than or equal to the visible light transmittance of the shielding portion 61.

[0080] Please see Figure 3 or Figure 4 , Figure 4 and Figure 3 The difference lies in the type of light-emitting element 51 selected. In one embodiment, the distance between the inner edge of the first light-blocking layer 20 and the central axis O of the first glass plate 10 is less than the distance between the inner edge of the shielding portion 61 and the central axis O of the first glass plate 10, and the horizontal distance d between the inner edge of the first light-blocking layer 20 and the inner edge of the shielding portion 61 is set to 1mm to 10mm. In this way, the first light-blocking layer 20 can completely cover the inner edge of the shielding portion 61, that is, it can block the junction of the shielding portion 61 and the visible light transmitting portion 62, preventing the junction of the shielding portion 61 and the visible light transmitting portion 62 from being exposed to the transparent area of ​​the glass and affecting the appearance.

[0081] Of course, please refer to the following: Figure 1 and Figure 2In some embodiments, the first adhesive layer 60 may also be integrated with the shielding portion 61, that is, the whole is configured as the shielding portion 61. In other words, the first adhesive layer 60 does not need to be provided with different adhesive materials in the visible light transmitting portion 62.

[0082] Please see Figure 1 , Figure 5 and Figure 6 Because some light-emitting elements 51 have large dimensions, their thickness along the thickness direction of the glass assembly approaches or exceeds that of conventional laminated glass adhesive layers. To prevent the light-emitting elements 51 from coming into contact with the glass during lamination, which could damage the light-emitting elements 51 or cause the glass to break, in some embodiments, the thickness of the first adhesive layer 60 and / or the thickness of the second adhesive layer 70 are increased.

[0083] Please see Figure 1 , Figure 5 and Figure 6 In one embodiment, the light-emitting glass assembly further includes a third adhesive layer 80 disposed between the first adhesive layer 60 and the light-emitting element 51. Thus, by providing the third adhesive layer 80, the thickness of the adhesive layer between the light-emitting element 51 and the first glass plate 10 can be increased, thereby reducing the risk of damage to the light-emitting element 51 or glass breakage during lamination. The third adhesive layer 80 can be a light-colored polymer adhesive material, with a specific structure as shown below. Figure 6 As shown, similar to the first adhesive layer 60, it can also be a high-transmittance (transmittance > 50%) polymer adhesive material, with a specific structure as follows. Figure 5 As shown, it can also be set to a polymer adhesive material with a darker color to increase the shielding performance of the internal light-emitting element and the intermediate film material.

[0084] Please see Figure 7 In one embodiment, the light-emitting glass assembly further includes an intermediate film 90 disposed between the shielding portion 61 and the light-emitting element 51. Specifically, the intermediate film 90 includes a color film and / or a functional film. Thus, especially when the color of the light-emitting element 51 is relatively limited, the light emitted by the light-emitting element 51 combines with the intermediate film 90 to achieve a variety of light-emitting colors.

[0085] Specifically, for example, the light-emitting element 51 emits white light and can be combined with colored film materials to achieve a variety of light-emitting colors. The colored film materials include, but are not limited to, colored PVB, PET, or PI films. Alternatively, a white light-emitting element 51 can be combined with a functional film material. The functional film material can be a film material with touch functionality, thereby enabling the switching of light emission on / off or light emission brightness, color, mode, etc., through touch or gestures. Alternatively, a combination of the white light-emitting element 51, colored film materials, and functional film materials can be selected.

[0086] Since it is often difficult to form a tight and good bonding effect between the intermediate film 90 and the light-emitting element 51, the intermediate film 90, polymer adhesive materials of various colors, light-emitting element 51, polymer adhesive materials of various colors and the second glass plate 30 can be arranged in sequence below the shielding part 61 that is in direct contact with the first glass plate 10.

[0087] Please see Figure 7 In one embodiment, the light-emitting glass assembly further includes a third adhesive layer 80 disposed between the first adhesive layer 60 and the light-emitting element 51, and an intermediate film 90 disposed between the first adhesive layer 60 and the third adhesive layer 80. This allows the intermediate film 90 to be securely fixed inside the glass assembly.

[0088] It is understandable that the intermediate membrane 90 can also be on the same layer as the third adhesive layer 80, and the two have similar thicknesses. Specifically, the intermediate membrane 90 is arranged around the third adhesive layer 80 in the circumferential direction. In other words, the central part is the third adhesive layer 80, and the outer part is the intermediate membrane 90.

[0089] Please see Figure 7 In one embodiment, the third orthographic projection of the intermediate film 90 on the surface of the first glass plate 10 completely covers the first orthographic projection of the perforated hole 21 on the surface of the first glass plate 10, and the distance S2 between the outline of the third orthographic projection and the outline of the first orthographic projection is set to 0.5mm to 5mm. Specifically, the distance S2 is set to 0.5mm, 1mm, 2mm, 3mm, 4mm, 4.5mm, 5mm, etc.

[0090] In one embodiment, the fourth orthographic projection of the functional film on the surface of the first glass plate 10 completely covers the first orthographic projection of the perforation 21 on the surface of the first glass plate 10. Specifically, the surface shape of the functional film can be adapted to the surface shape of the second light-blocking layer 40, i.e., covering the black edge area of ​​the glass assembly, enabling touch functionality at any position in the black edge area; or it can be adapted to the overall shape of the first glass plate 10, i.e., covering the entire surface area of ​​the glass assembly, enabling touch functionality at any position on the entire surface of the glass assembly.

[0091] Please see Figure 8In one embodiment, the light-emitting glass assembly further includes a circuit board 52 disposed between the first adhesive layer 60 and the second adhesive layer 70. The light-emitting elements 51 include LEDs, each connected to the circuit board 52. LEDs have numerous advantages, including small size, low power consumption, high brightness, good monochromaticity, and low cost, and are currently widely used in various industries such as lighting, decoration, and communication. In the existing technology of passenger vehicles, LEDs are widely used in vehicle lighting, interior ambiance creation, and interior lighting, but exploration of their integration with vehicle window glass is just beginning. To ensure stable operation of the LEDs and uniform brightness among them, a stable and consistent voltage and driving current are required for each LED. Therefore, each light-emitting element 51 must have corresponding electrical connection positions (pads or die bond points), sufficiently low-resistance wires, and pins connected to an external driving power supply. Since vehicle window glass is typically curved, the circuit board 52 is specifically chosen as a flexible circuit board. The flexible circuit board contains pre-set pads, low-resistance wires connected to the pads, and gold fingers connected to an external driving power supply. LEDs (specifically, LED beads or light-emitting chips) are electrically connected to corresponding pads on a flexible circuit board using soldering methods such as reflow soldering, wave soldering, or die bonding. Additionally, to enhance the reliability of the electrical connection between the LED and the flexible circuit board, protective adhesive 53 can be applied around the LED to prevent oxidation of the electrical connection points or connection failure due to external moisture or mechanical forces.

[0092] Furthermore, since the LED light requires connection to an external driving power supply, the gold fingers and surrounding portion of the flexible circuit board connecting to the external driving power supply are located outside the laminated glass, while the light-emitting portion of the flexible circuit board is positioned between the polymer adhesive layers of the laminated glass. The light emitted by the LED light on the flexible circuit board is emitted through the perforated area 21 on the first glass plate 10.

[0093] Please see Figures 9 to 13 In some embodiments, multiple light-emitting elements 51 and multiple perforated holes 21 are provided, with each perforated hole 21 corresponding to a specific light-emitting element 51. The perforated hole 21 area can be a circular hole centered on the light-emitting element 51. When the distance between two adjacent light-emitting elements 51 is greater than the diameter of the perforated hole 21, each perforated hole 21 is configured as a series of independent circular holes, such as... Figure 10 As shown; when the distance between two adjacent light-emitting elements 51 is less than the diameter of the cutout hole 21, each cutout hole 21 is set as a series of circles with partially overlapping areas, such as Figure 11 As shown.

[0094] It should be noted that smaller spacing (D) of the perforated holes 21 ensures a smaller color difference area and less exposure of the underlying flexible circuit board, resulting in a better overall appearance of the window. However, during the lamination process of the flexible circuit board and the polymer adhesive material, there may be some positioning errors. Therefore, smaller spacing (D) of the perforated holes 21 may cause some of the light emitted by multiple light-emitting elements 51 to be partially covered by ink outside the perforated holes 21, resulting in uneven brightness at different locations. To ensure that all light-emitting elements 51 are centered in the perforated hole area, additional positioning fixtures or positioning steps may be required, which may increase process complexity, cost, and yield. Conversely, larger spacing (D) of the perforated holes 21 can reduce the probability of light from the light-emitting elements 51 being blocked, simplifying the process steps. However, it will increase the exposure of the color difference area and the underlying flexible circuit board. The shielding part 61 can minimize the color difference between the larger spacing (D) of the perforated holes 21 area and the black edge area, and can also shield the flexible circuit board.

[0095] Please see Figures 9 to 13 In some examples, the cutout 21 is not limited to being a circular hole. Depending on the shape of the light-emitting element 51 and the distribution of light intensity, the cutout 21 can also be set as a rectangle or other shapes centered on the light-emitting element 51. When the rectangular size is small, each cutout 21 is set as a series of independent rectangular areas, such as... Figure 12 As shown. To simplify the process, the area of ​​the cutout holes 21 can also be increased, and the area where the light-emitting element 51 is located and the surrounding 0.5~5mm area can be completely cut out, that is, the cutout holes 21 can be connected into one piece, for example, forming a shape like... Figure 13 The rectangular opening shown.

[0096] Please see Figures 14 to 17 The flexible circuit board includes, but is not limited to, being elongated. The flexible circuit board and the LEDs distributed on it can be flexibly adjusted and set as needed, and are not limited here. For example, it can be set as follows: Figure 14 The battery shape shown; it can also be set as follows: Figure 15 The letter shapes shown; or they can be set as follows: Figure 16 The circle shown; it can also be set as follows Figure 17Various shapes, such as triangles, can be shown. In addition to simultaneously illuminating all the LEDs on the flexible circuit board, circuit settings can be used to illuminate the LEDs one by one, in units of three, or with differences and variations in brightness between adjacent LEDs 51. This allows for decorative effects such as indicating battery power increases, weather, driving range, welcome messages, flashing lights, and flowing lights. Besides arranging LEDs of the same color on the flexible circuit board, single-color LEDs 51 of various colors, such as red, green, blue, white, and yellow, or LEDs with multiple RGB colors, can be arranged alternately or in combination to achieve color changes in the illuminated pattern.

[0097] Please see Figure 1 In some embodiments, a vehicle includes a light-emitting glass component from any of the above embodiments.

[0098] In the aforementioned vehicle, since the shielding part 61 can completely cover the perforated hole 21, the visible light transmittance of the shielding part 61 is 2% to 50%, the absolute value of the deviation between the a value of the shielding part 61 and the a value of the first light blocking layer 20 is set within 0.5, the absolute value of the deviation between the b value of the shielding part 61 and the b value of the first light blocking layer 20 is set within 0.5, and the absolute value of the deviation between the L value of the shielding part 61 and the L value of the first light blocking layer 20 is set within 2.5. In this way, the color difference between the perforated hole 21 area and the first light blocking layer 20 can be compensated to the greatest extent, so that when the light-emitting element 51 is in the off state, the perforated hole 21 set in the first light blocking layer 20 is not easily noticed when the first glass plate 10 is observed from a certain distance (e.g., >60cm). In addition, when the light-emitting element 51 is in the working state, the light of the light-emitting element 51 can pass through the shielding part 61 and the perforated hole 21 and be emitted outward, thus being observed.

[0099] In summary, the luminescent glass assembly and vehicle of this application have at least the following advantages:

[0100] 1. By setting a polymer adhesive material with a certain color under the first glass plate 10, the color difference between the hollow hole 21 area and the black edge area on the first glass plate 10 is compensated, making it possible to open holes inside the black edge area while minimizing the degradation of the appearance.

[0101] 2. A polymer adhesive material of a certain color provides good shielding for the light-emitting element 51, intermediate film 90, or polymer adhesive materials of various colors on the side away from the first glass plate 10, making it possible to arrange light-emitting devices of different colors, such as LED beads or chips, surface light sources, fluorescent light sources, or other colored films such as red PET, inside the laminated glass.

[0102] 3. Because the colored polymer adhesive material also provides good shielding for the other polymer adhesive materials below it, the remaining polymer adhesive materials below this layer can be selected from various polymer adhesive materials with darker colors or higher transmittance. The transmittance range of the laminated glass can be designed and adjusted to a greater extent.

[0103] 4. The light-emitting element 51 or the intermediate film material 90 is arranged in a position corresponding to the hollow hole 21 area of ​​the first glass plate 10. By actively emitting light, it can bring more colors to the car window, add highlights to the overall vehicle appearance design, and realize decorative effects such as preset pattern light emission, light flashing, and flowing light.

[0104] 5. The light-emitting element 51 is arranged in a position corresponding to the hollow hole 21 area of ​​the first glass plate 10. Through circuit settings, it can realize various functions such as indicating battery power increase, weather, driving range, and welcome message.

[0105] 6. Since the color difference between the hollow hole 21 area and the black edge area on the first glass plate 10 is compensated, it makes it possible to have a larger hollow hole 21 area. This reduces the accuracy requirement for the alignment of multiple light-emitting elements 51 with the hollow hole 21 area before the lamination process, saves process time, reduces process cost, and improves product yield.

[0106] 7. By arranging the light-emitting element 51 and the intermediate film 90 inside the laminated glass, the appearance requirements of the light-emitting element 51 or the intermediate film 90 are reduced, and the development cost of the light-emitting element 51 or the intermediate film 90 is saved.

[0107] 8. Since the light-emitting element 51, the intermediate film material 90, and the polymer adhesive material with a certain color used to compensate for color difference can be arranged only in the black edge area of ​​the laminated glass, they do not affect the appearance of the transparent area of ​​the car window, thus ensuring the transparency and appearance of the transparent area.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0109] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element.
