[0031] In a third aspect, an embodiment of the present application provides a vehicle. The vehicle includes a body, a power source, and the hemming assembly. The hemming assembly and the power source are mounted on the body. The power source is electrically connected to the controller of the hemming assembly and controls the display of the decorative pattern of the display glass.

[0032] In the related art, there is a method of using multi-color ink or mirror ink to form a pattern to decorate the window glass in existing vehicles. The decorative pattern formed in this way has a single shape and a single color, and the effect of changing the decorative pattern cannot be achieved. Therefore, this decorative method cannot be used in scenarios where the window glass needs to be displayed diversely. In addition, there is also a method of decorating the window glass by integrating decorative pattern-like decorative parts and lighting components in existing vehicles. The decorative parts can be aluminum decorative parts, plastic decorative parts, etc. The lighting components can achieve dynamic changes in the decorative pattern. However, the installation process of this method is complex, and the displayed decorative pattern is too fancy, making it difficult to achieve a simple and high-class display effect. At the same time, the brightness of the lighting components in this method is high, and they cannot be displayed during driving, so their usage scenarios are also limited.

[0033] In the embodiments of the present application, the display glass of the edge wrapping assembly integrates a flexible display film layer. The display layer in the flexible display film layer includes multiple display partitions. Each display partition is connected to a first sub-layer of an electrode layer, and each first sub-layer is connected to a trace. All the traces are connected to a controller. The traces can be connected in series or in parallel. When the controller is powered on, the controller can separately control or simultaneously control the display partitions to display different or the same decorative patterns through the traces, and realize the color change of the decorative patterns through different color filters, avoiding the single color and single shape of the decorative patterns, and also avoiding the overly fancy decorative patterns displayed by using lighting components, achieving a simple and high-class display effect of the decorative patterns. At the same time, according to the display needs, the dynamic change of the decorative patterns can also be realized; furthermore, it meets the diverse display requirements of the display glass and realizes the display in different scenarios. At the same time, the flexible display film layer can set the number, position, and shape of the display layer, color filter, and electrode layer according to the display requirements. For example, multiple display layers are arranged at intervals, so that the display glass can save the materials required for display to a certain extent while meeting the display requirements.

[0034] Moreover, the area of the display window is smaller than the area of the display region of the display layer, that is, the cutting edge of the display layer can be blocked by the display window of the first shielding layer. While ensuring that the decorative pattern can be observed by the people outside the vehicle, it can also prevent the people outside the vehicle from observing the edge of the display layer, ensuring the appearance of the display glass.

[0035] In the embodiments of the present application, the display glass uses a flexible display film layer to display decorative patterns. Compared with the prior art in which integrated decorative pattern-like decorative parts and lighting components are used for decoration, the brightness of the decorative patterns in the embodiments of the present application is low, so that the display function of the display glass can be used during driving, breaking through the limitation that the display glass cannot be displayed during driving and expanding the application scenarios of the display glass.

[0046] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a means of transportation provided by an embodiment of the present application.

[0047] An embodiment of the present application provides a means of transportation 1000, and the means of transportation 1000 can be a vehicle, a ship, a submarine, an airplane, etc. The means of transportation 1000 in the embodiments of the present application is described by taking a vehicle as an example, as Figure 1 shown.

[0048] For the convenience of description, in the present application, the width direction of the means of transportation 1000 is defined as the X-axis direction, the length direction is defined as the Y-axis direction, and the height direction is defined as the Z-axis direction; wherein, the X-axis, Y-axis, and Z-axis directions are perpendicular to each other in pairs.

[0049] It should be noted that the orientation terms such as "top", "bottom", "left", "right", "front", and "back" mentioned in the description of the present application are described based on the orientation of the means of transportation 1000 shown in the Figure 1 accompanying drawings. The forward direction in the length direction of the means of transportation 1000 is the positive direction of the Y-axis, the direction from left to right in the width direction of the means of transportation 1000 is the positive direction of the X-axis, and the direction away from the ground in the width direction of the means of transportation 1000 is the positive direction of the Z-axis.

[0050] In this embodiment, the means of transportation 1000 includes a hemming assembly 100 and a body 200. The hemming assembly 100 is connected to the vehicle body. The means of transportation 1000 further includes a power source (not shown in the figure). The power source is installed on the vehicle body and is used to provide necessary power support for the means of transportation 1000 or support various functions of the means of transportation 1000.

[0051] Please refer to Figure 2 , Figure 2 ForFigure 1 Schematic structural diagram of an exemplary hemming assembly of a vehicle shown.

[0052] The hemming assembly 100 may be a side window hemming assembly 100, a corner window hemming assembly 100, a sunroof hemming assembly 100, a front windshield hemming assembly 100, or a rear windshield hemming assembly 100, etc. The display glass 10 may be a side window glass, a corner window glass, a sunroof glass, a front windshield glass, a rear windshield glass of a vehicle, etc. Hereinafter, the hemming assembly 100 will be taken as an example of the corner window hemming assembly 100, and the display glass 10 will be taken as an example of the corner window glass of the vehicle for detailed description, but it should be understood that it is not limited thereto in practice.

[0053] In this embodiment, the hemming assembly 100 includes a display glass 10, a glass hemming 20, and a guide rail 30. The guide rail 30 is connected to the body 200. Both the display glass 10 and the glass hemming 20 are mounted on the guide rail 30. The glass hemming 20 surrounds and wraps the edge of the display glass 10.

[0054] The display glass 10 includes an outer glass surface 101, an inner glass surface 102, and an outer side surface 103. The outer glass surface 101 and the inner glass surface 102 are arranged opposite to each other along the thickness direction of the display glass 10. The outer side surface 103 is connected to the outer glass surface 101 and the inner glass surface 102. The glass hemming 20 is connected to the outer side surface 103 of the display glass 10 and is connected to the edges of the outer glass surface 101 and the inner glass surface 102 to seal the edge of the display glass 10, prevent water vapor from entering the interior of the display glass 10 from the edge of the display glass 10 and affect the performance of the display glass 10, and extend the service life of the display glass 10. In some embodiments, under the condition that the glass hemming 20 sufficiently seals the display glass 10, the glass hemming 20 may be only connected to the outer side surface 103 of the display glass 10, or the glass hemming 20 may be only connected to the outer side surface 103 and the outer glass surface 101 of the display glass 10, or the glass hemming 20 may be only connected to the outer side surface 103 and the inner glass surface 102 of the display glass 10.

[0055] Please refer to Figure 2 、 Figure 3 and Figure 4 , Figure 2 The display glass of the hemming assembly of Figure 3 is an example, which does not constitute a limitation on the shape and structure of the hemming assembly, Figure 2 is a cross-sectional schematic diagram of a partial structure of the hemming assembly shown in Figure 4 is Figure 3 a disassembled cross-sectional schematic diagram of a partial structure of the hemming assembly shown. It should be noted that Figure 2 shows a perspective structure of a flexible display film layer of the display glass, and Figure 2The dashed line in it represents the edge line of the flexible display film layer.

[0056] In this embodiment, the display glass 10 includes a glass body 1 and a flexible display film layer 2. The flexible display film layer 2 is disposed on the glass body 1 and is used to display decorative patterns. When the power is applied to the flexible display film layer 2, people can observe the decorative patterns displayed by the flexible display film layer 2 through the glass body 1.

[0057] As Figure 2 shown, the glass body 1 includes a black edge region M and a perspective region N. The black edge region M surrounds and connects to the edge of the perspective region N. The perspective region N is used for people's line of sight to pass through normally. The black edge region M is used to shield people outside the vehicle from observing the edge of the flexible display film layer 2, and is also used to shield people inside the vehicle from observing the structure of the flexible display film layer 2. The decorative patterns displayed after the flexible display film layer 2 is powered on can be located in the black edge region M and / or the perspective region N. Exemplarily, the decorative patterns displayed after the flexible display film layer 2 is powered on are located within the black edge region M of the glass body 1 and are displayed in the black edge region M.

[0058] As Figure 3 and Figure 4 shown, in this embodiment, the glass body 1 has a laminated glass structure. The glass body 1 includes an outer glass plate 11, an adhesive layer 12, and an inner glass plate 13. Along the thickness direction of the glass body 1, the outer glass plate 11, the adhesive layer 12, and the inner glass plate 13 are sequentially stacked and connected. When the display glass 10 is installed on the body 200, the outer glass plate 11 faces the outside of the vehicle 1000, and the inner glass plate 13 faces the inside of the vehicle 1000.

[0059] As Figure 4 shown, the outer glass plate 11 includes a first surface 111 and a second surface 112. The first surface 111 and the second surface 112 are arranged opposite to each other along the thickness direction of the outer glass plate 11. When the display glass 10 is installed on the body 200, the first surface 111 of the outer glass plate 11 faces the outside of the vehicle 1000 and can serve as the outer glass surface 101 of the display glass 10. The second surface 112 of the outer glass plate 11 faces the adhesive layer 12. The outer glass plate 11 further includes a first side surface 113. The first side surface 113 surrounds and connects the first surface 111 and the second surface 112 of the outer glass plate 11.

[0060] The inner glass plate 13 includes a third surface 131 and a fourth surface 132. The third surface 131 and the fourth surface 132 are arranged opposite to each other along the thickness direction of the inner glass plate 13. When the display glass 10 is installed on the main body 200, the third surface 131 of the inner glass plate 13 faces the adhesive layer 12. The fourth surface 132 of the inner glass plate 13 faces the interior of the vehicle 1000 and can serve as the inner glass surface 102 of the display glass 10. The inner glass plate 13 further includes a second side surface 133. The second side surface 133 surrounds and connects the third surface 131 and the fourth surface 132 of the inner glass plate 13.

[0061] The adhesive layer 12 is connected to the second surface 112 of the outer glass plate 11 and the third surface 131 of the inner glass plate 13. The adhesive layer 12 includes a third side surface 121. The third side surface 121 surrounds and connects the two surfaces in the thickness direction of the adhesive layer 12. The adhesive layer 12 is used to bond the outer glass plate 11 and the inner glass plate 13 together to form a laminated glass structure, improving the structural strength of the display glass 10 and preventing the glass debris from splashing and scratching the driver or passengers inside the vehicle 1000 after the outer glass plate 11 or the inner glass plate 13 is broken, so that the display glass 10 meets the safety standards and regulatory requirements in more scenarios.

[0062] The adhesive layer 12 can be a single-layer structure or a multi-layer structure. Examples of the multi-layer structure include a double-layer structure, a three-layer structure, a four-layer structure, a five-layer structure, etc. The adhesive layer 12 can be made of, but not limited to, a transparent thermoplastic polymer film. For example, the material of the adhesive layer 12 can be selected from at least one of polyvinyl butyral (PVB), ethylene-vinyl acetate copolymer (EVA), etc. Alternatively, the adhesive layer 12 can be a layer structure formed by curing a transparent colloid. The embodiments of the present application do not limit this.

[0063] In one implementation, when the adhesive layer 12 is made of a PVB film layer or an EVA film layer, the adhesive layer 12 can be a multi-layer structure. Exemplarily, the adhesive layer 12 is a three-layer structure, that is, the adhesive layer 12 includes three PVB film layers, or the adhesive layer 12 includes three EVA film layers, or the adhesive layer 12 includes a three-layer film layer composed of a mixture of a PVB film layer and an EVA film layer. The three film layers are sequentially stacked and connected along the thickness direction of the adhesive layer 12. Two of the film layers are located on the opposite sides in the thickness direction of the flexible display film layer 2 and sandwich the flexible display film layer 2, and the other film layer fills between the two film layers and wraps the flexible display film layer 2. The outer glass plate 11 and the inner glass plate 13 sandwich the three film layers and the flexible display film layer 2, so that the flexible display film layer 2, the outer glass plate 11 and the inner glass plate 13 are fixedly connected through the adhesive layer 12.

[0064] In one embodiment, when the adhesive layer 12 is formed by curing a transparent colloid, the flexible display film layer 2 is installed between the outer glass plate 11 and the inner glass plate 13. By pouring the colloid between the outer glass plate 11 and the inner glass plate 13, the colloid is cured to form the adhesive layer 12, so that the flexible display film layer 2, the outer glass plate 11 and the inner glass plate 13 are fixedly connected through the adhesive layer 12.

[0065] It should be noted that the flexible display film layer 2 itself has flexibility. In the case where the display glass 10 is required to be a curved glass, when the flexible display film layer 2 is laminated with the glass body 1, the flexibility of the flexible display film layer 2 itself can ensure its good adhesion to the glass body 1, avoiding the generation of bubbles between the flexible display film layer 2 and the glass body 1 after lamination. At the same time, the flexible display film layer 2 has sufficient flexibility to ensure that its own performance will not be damaged after bending. Among them, the lamination means that the flexible display film layer 2 and the glass body 1 are bonded together through operations such as heating and pressing.

[0066] In this embodiment, the first side surface 113 of the outer glass plate 11, the second side surface 133 of the inner glass plate 13 and the third side surface 121 of the adhesive layer 12 face the same direction, and the first side surface 113, the second side surface 133 and the third side surface 121 together constitute the outer side surface 103 of the glass body 1, that is, together constitute the outer side surface 103 of the display glass 10. The glass edge 20 is connected to the first side surface 113 of the outer glass plate 11, the second side surface 133 of the inner glass plate 13 and the third side surface 121 of the adhesive layer 12, and is connected to the edges of the first surface 111 of the outer glass plate 11 and the fourth surface 132 of the inner glass plate 13, preventing water vapor from entering the glass body 1 through the gap between the outer glass plate 11, the adhesive layer 12 and the inner glass plate 13, and thus avoiding the contact between the water vapor and the flexible display film layer 2 resulting in a short circuit of the circuit.

[0067] The glass body 1 further includes a first shielding layer 14 and a second shielding layer 15. The first shielding layer 14 is connected to the second surface 112 of the outer glass plate 11. The second shielding layer 15 is connected to the fourth surface 132 of the inner glass plate 13. The materials of the first shielding layer 14 and the second shielding layer 15 can be, but are not limited to, dark inks. Both the first shielding layer 14 and the second shielding layer 15 play a shielding role.

[0068] The first shielding layer 14 includes a display window 141. The display window 141 penetrates through the two surfaces of the first shielding layer 14 in the thickness direction. The display window 141 can accommodate a part of the adhesive layer 12, and the display window 141 is used for allowing people outside the vehicle 1000 to observe the decorative pattern displayed after the flexible display film layer 2 is powered on. The number of the display windows 141 can be one or more. When the number of the display windows 141 is multiple, the multiple display windows 141 are arranged at intervals along the extending direction of the glass body 1. It should be noted that the number and positions of the display windows 141 can be set according to the actual display requirements of the flexible display film layer 2. The present application does not make any requirements in this regard.

[0069] In this embodiment, the part of the glass body 1 covered by the first shielding layer 14 and the second shielding layer 15 can be regarded as the "black edge area M" of the glass body 1, and the part of the glass body 1 not covered by the first shielding layer 14 and the second shielding layer 15 can be regarded as the "perspective area N" of the glass body 1. In some embodiments, according to the display requirements of the display glass 10, the glass body 1 may not include the first shielding layer 14 and the second shielding layer 15 either. That is, there is no "black edge area M" in the glass body 1, and the entire glass body 1 is a "transparent area". At this time, the decorative pattern displayed after the flexible display film layer 2 is powered on is located in the transparent area of the display glass 10 and is displayed within the transparent area.

[0070] Please refer to Figure 3 、 Figure 4 and Figure 5 , Figure 5 is Figure 3 a top view of an example of the display layer of the flexible display film layer shown.

[0071] As Figure 3 and Figure 4As shown in the figure, the flexible display film layer 2 includes a flexible substrate 21, a display film 24, a trace 28, and a controller 29. The controller 29 is located outside the glass body 1 and is used for electrically connecting to the power supply of the vehicle 1000. A part of the flexible substrate 21 extends into the adhesive layer 12 of the glass body 1. Another part of the flexible substrate 21 passes through the third side surface 121 of the adhesive layer 12 and the glass edge 20. The flexible substrate 21 is used to carry and support the display film 24 and the trace 28. The display film 24 is stacked and connected to one side of the flexible substrate 21 in the thickness direction. The display film 24 is opposite and spaced from the display window 141 of the first shielding layer 14, and the display film 24 is used to display a decorative pattern after being powered on. The trace 28 is stacked on the side of the flexible substrate 21 facing away from the display film 24. The trace 28 can be regarded as being laid by a conductive material. The trace 28 can be, but is not limited to, silver paste, or it can also be a conductive copper foil, or a conductive aluminum foil, etc. The silver paste trace 28 can be formed on the surface of the flexible substrate 21 by printing. One end of the trace 28 passes through the third side surface 121 of the adhesive layer 12 and the glass edge 20 and is electrically connected to the controller 29, and the other end of the trace 28 passes through the flexible substrate 21 and is electrically connected to the display film 24. That is, a part of the trace 28 is located inside the glass body 1 and the glass edge 20, and the other part is located outside the glass body 1. It can be understood that the display film 24 is electrically connected to the controller 29 through the trace 28. When the power supply powers on the controller 29, the controller 29 controls the display film 24 to display. In other embodiments, the flexible substrate 21 does not need to extend out of the glass body 1, that is, the flexible substrate 21 is connected through an external trace 28 to achieve the electrical connection between the controller 29 and the display film 24.

[0072] The flexible substrate 21 includes a first bearing surface 211 and a second bearing surface 212. The first bearing surface 211 and the second bearing surface 212 are arranged opposite to each other along the thickness direction of the flexible substrate 21. The flexible substrate 21 further includes a first part 22 and a second part 23. The first part 22 and the second part 23 are connected as a whole, and the extending direction of the first part 22 is the same as the extending direction of the second part 23. The same-side surfaces of the first part 22 and the second part 23 in the thickness direction constitute the first bearing surface 211, and the other same-side surfaces of the first part 22 and the second part 23 in the thickness direction constitute the second bearing surface 212. The first part 22 is embedded in the adhesive layer 12 of the glass body 1 and the glass edge 20 and is used to carry and support the display film 24 and part of the trace 28. The second part 23 is located outside the glass body 1 and is used to carry the other part of the trace 28. The first bearing surface 211 of the first part 22 carries and supports the display film 24, and the second bearing surface 212 of the first part 22 and the second part 23 is used to carry and support the trace 28.

[0073] The first part 22 further includes a perforation 221. The perforation 221 penetrates through the first bearing surface 211 and the second bearing surface 212 of the first part 22. The perforation 221 is used for the trace 28 connected to the display film 24 to pass through. The number of perforations 221 can be one or more. When the number of perforations 221 is multiple, the multiple perforations 221 are arranged at intervals along the extending direction of the first part 22. In this embodiment, the flexible substrate 21 can be made of, but not limited to, a flexible PVB film layer. The shape of the flexible substrate 21, that is, the shapes of the first part 22 and the second part 23, can be set according to the actual display requirements of the display glass 10. This application does not make requirements for this.

[0074] The display film 24 includes an electrode layer 25, a display layer 26, and a color filter 27. Along the thickness direction of the display film 24, the electrode layer 25, the display layer 26, and the color filter 27 are sequentially stacked and connected. The electrode layer 25 is used to connect to the first bearing surface 211 of the first part 22. Along the thickness direction of the display film 24, the projection of the display layer 26 is completely within the projection range of the color filter 27, and the projection of the display layer 26 is completely within the projection range of the electrode layer 25. That is, the area of the display layer 26 is less than or equal to the area of the color filter 27 and less than or equal to the area of the electrode layer 25. The display layer 26 is used to display a decorative pattern. The color filter 27 is colored, and it can make the decorative pattern have a color effect. The electrode layer 25 is used to be electrically connected to the trace 28 and serves as an electrode for the display layer 26. The electrode layer 25 has a printed pattern, and the electrode layer 25 can generate a uniform electric field after being powered on, so that the display layer 26 displays a decorative pattern under the action of the uniform electric field, and the decorative pattern is consistent with the printed pattern. In this embodiment, the display layer 26 can be made of an electronic ink (E ink) film. The E ink film is a multi-color level black and white display film. Using the E ink film for the display layer 26 can achieve multiple color levels on the basis of black and white display, so as to present rich image details and layering. The electrode layer 25 can be made of, but not limited to, materials with good electrical conductivity such as carbon ink. The carbon ink is dark in color, so that the electrode layer 25 can also be used as the display background of the display layer 26. When the display layer 26 displays a decorative pattern, the electrode layer 25 can increase the contrast of the decorative pattern, thereby improving the display effect. The carbon ink can be formed on the flexible substrate 21 by printing. In some embodiments, the display film 24 may not include a color filter 27, and the color of the decorative pattern displayed by the display layer 26 is the color of the display layer 26 itself.

[0075] The display film 24 further includes a conductive member T. The conductive member T is located between the display layer 26 and the electrode layer 25. The conductive member T is embedded on the side of the display layer 26 facing the electrode layer 25, and the conductive member T is connected and conductive to the electrode layer 25. Along the thickness direction of the display film 24, the projection of the conductive member T is completely within the projection range of the display layer 26. In this embodiment, the conductive member T may be a thin film transistor array.

[0076] The electrode layer 25 includes a first sublayer 251 and a second sublayer 252. The first sublayer 251 and the second sublayer 252 are arranged at intervals. The first sublayer 251 is used as an electrode of the display layer 26 and is used to be electrically connected to the wiring 28. The second sublayer 252 is used as another electrode of the display layer 26 and is used to be electrically connected to the conductive member T. In other words, the first sublayer 251 and the second sublayer 252 are disconnected to ensure that there is no circuit short circuit problem when the electrode layer 25 is powered on. The number of the first sublayer can be one or more. The number of the second sublayer 252 is one.

[0077] The first sublayer 251 has a printed pattern, and the printed pattern can be formulated according to the display requirements of the display glass 10. The first sublayer 251 also has at least one through hole 253. The through hole 253 runs through both surfaces of the first sublayer 251 in the thickness direction and avoids the printed pattern. The through hole 253 is used for the wiring 28 electrically connected to the first sublayer 251 to pass through. When the electrode layer 25 is energized, a uniform electric field is formed between the first sublayer 251 and the second sublayer 252, and the uniform electric field can act on the display layer 26, so that the display layer 26 displays under the action of the uniform electric field.

[0078] The display layer 26 includes a display area 261. The boundary of the display area 261 has a certain spacing distance S from the edge of the display layer 26, and the spacing distance S is at least greater than 0.2 mm, so as to prevent the boundary of the display area 261 from being too close to the edge of the display layer 26, which may cause the display area 261 to easily leak electricity, thereby fully protecting the performance of the display area 261. The display area 261 includes display partitions 262, which are used to display decorative patterns. The number of display partitions 262 is the same as the number of the first sublayers 251 of the electrode layer 25, which may be one or more. The shape of the display partition 262 may be, but is not limited to, a triangle, a quadrilateral or other irregular polygons. The size of the display partition 262 should satisfy the arrangement of the first sublayer 251 and the wiring 28 corresponding thereto, and satisfy the arrangement of the through-holes 253 of the first sublayer 251. For example, as Figure 5As shown, the display area 261 includes multiple display partitions 262, and the multiple display partitions 262 include rectangles, triangles and irregular polygons. The decorative patterns displayed in each display partition 262 can be the same or different. The length A of each side of the boundary of each display partition 262 is greater than or equal to 0.5 mm, so as to avoid the display partition 262 being too small to correspond to the arrangement of the first sub-layer 251, and to avoid the inability to set the through hole 253 on the first sub-layer 251 and the corresponding connecting line 28.

[0079] In this embodiment, when there are multiple display partitions 262, multiple display partitions 262 are spaced apart. The number of first sublayers 251 is multiple. Multiple first sublayers 251 are spaced apart from each other, and the interval H between two adjacent first sublayers 251 is greater than or equal to 0.05 mm, so as to avoid the connection between two adjacent first sublayers 251 and the occurrence of a circuit short circuit. Each first sublayer 251 is connected to a display partition 262, and the printed pattern of the first sublayer 251 is consistent with the decorative pattern displayed by the display partition 262. Among them, the printed patterns of the multiple first sublayers 251 can be the same or different, that is, the decorative patterns that need to be displayed in the multiple display partitions 262 can be the same or different. In addition, the second sublayer 252 is spaced apart from the multiple first sublayers 251 to avoid contact between the multiple first sublayers 251 and the second sublayer 252, thereby avoiding a circuit short circuit when the electrode layer 25 is energized, thereby ensuring the display function of the display layer 26.

[0080] In some embodiments, Figure 5 As shown, the shape of some display layers 26 may have hollows 263 according to the shape requirements of the display decorative pattern, and the hollows 263 penetrate the two surfaces of the display layer 26 in the thickness direction. The hollows 263 avoid the decorative pattern that the display layer 26 needs to display, that is, along the thickness direction of the display film 24, the projection of the hollows 263 and the projection of the electrode layer 25 are staggered. The hollows 263 are adjacent to the display partitions 262. The display layer 26 is provided with hollows 263, which can save the use of the display layer 26 while not affecting the display of the decorative pattern of the display layer 26. The interval between the two display partitions 262 located on opposite sides of the hollows 263 needs to meet the arrangement of the corresponding first sublayer 251 and the wiring 28. Exemplarily, the display layer 26 includes two hollows 263, and the two hollows 263 are arranged at intervals along the width direction of the display layer 26. Both hollows 263 are arranged at one side edge of the length direction of the display layer 26 and extend to the other side edge of the length direction. Both hollows 263 are rectangular openings. The distance B between the two display partitions 262 on opposite sides of the hollow 263 is greater than or equal to 0.5 mm to avoid the display partitions 262 being too small to be arranged in the corresponding first sub-layer 251, and to avoid the through holes 253 being set on the first sub-layer 251 and the corresponding connecting lines 28.

[0081] Continue to refer to Figure 3 In this embodiment, the first part 22 of the flexible substrate 21 is surrounded by the glass edge 20 and the bonding layer 12, and the second part 23 is located outside the glass body 1 and the glass edge 20. The display film 24 is connected to the first bearing surface 211 of the first part 22; the bonding layer 12 wraps the display film 24. The trace 28 covers the second bearing surface 212 of the flexible substrate 21. Both ends of the trace 28 are electrically connected to the electrode layer 25 and the controller 29 respectively.

[0082] Specifically, the electrode layer 25, the display layer 26, and the color filter 27 are stacked in sequence on the first bearing surface 211 of the first part 22. Both the first sub-layer 251 and the second sub-layer 252 of the electrode layer 25 are connected to the first bearing surface 211 of the first part 22, and along the extending direction of the first part 22, the first sub-layer 251 and the second sub-layer 252 are arranged at intervals to prevent the first sub-layer 251 and the second sub-layer 252 from contacting and causing a short circuit. The through hole 253 of the first sub-layer 251 is coaxially arranged and communicated with the through hole 221 of the first part 22. The display layer 26 is connected to the side of the electrode layer 25 facing away from the first part 22. The display partition 262 of the display layer 26 is connected to the first sub-layer 251 of the electrode layer 25. Along the thickness direction of the display film 24, the projection of the display partition 262 is completely within the projection range of the first sub-layer 251. The conductive member T is located between the display layer 26 and the second sub-layer 252 of the electrode layer 25, and the conductive member T is embedded in the display layer 26 and connected and conducted with the second sub-layer 252. The conductive member T is located outside the display area 261, and along the thickness direction of the display glass 10, the projection of the conductive member T is completely within the projection range of the display layer 26. In addition, the projection of the conductive member T is completely within the projection range of the first shielding layer 14. That is, the conductive member T is blocked by the first shielding layer 14. The color filter 27 is stacked on the side of the display layer 26 facing away from the electrode layer 25 and completely covers the display area 261 of the display layer 26. One end of the trace 28 passes through the through hole 221 of the first part 22 and the through hole 253 of the first sub-layer 251 in sequence and is electrically connected to the first sub-layer 251. The other end of the trace 28 extends along the second bearing surface 212 of the flexible substrate 21, passes through the third side surface 121 of the bonding layer 12 and the glass edge 20, and is electrically connected to the controller 29. When the controller 29 is powered on, the controller 29 applies a voltage to the electrode layer 25 through the trace 28, so that a uniform electric field is formed between the first sub-layer 251 and the second sub-layer 252, and the display partition 262 of the display layer 26 displays a decorative pattern under the drive of the uniform electric field, wherein the decorative pattern is consistent with the printed pattern of the first sub-layer 251. The color filter 27 makes the decorative pattern displayed by the display layer 26 have a color effect.

[0083] When the number of display partitions 262 in the display area 261 of the display layer 26 is multiple, one first sub-layer 251 corresponding to each display partition 262 is connected to one trace 28. When multiple display partitions 262 need to be displayed simultaneously, multiple traces 28 corresponding to the multiple display partitions 262 can be connected in series, so that the controller 29 can control the multiple display partitions 262 to be displayed simultaneously. When multiple display partitions 262 need to be displayed independently, multiple traces 28 corresponding to the multiple display partitions 262 can be connected in parallel, so that the controller 29 can control each display partition 262 to be displayed independently. In addition, when the number of display partitions 262 is multiple, adjacent display partitions 262 are spaced apart from each other, so that two first sub-layers 251 corresponding to the two adjacent display partitions 262 can be arranged independently, which is beneficial to having a certain distance between the vias 253 on the two first sub-layers 251, and thus beneficial to the traces 28 connected to the two first sub-layers 251 being arranged independently, so as to achieve independent control of the multiple display partitions 262.

[0084] In this embodiment, along the thickness direction of the display glass 10, the display film 24 is opposite to and spaced apart from the display window 141 of the first shielding layer 14. The projection of the display window 141 is completely located within the display area 261 of the display layer 26. That is, the area of the display area 261 is larger than the area of the display window 141. The distance L from the projection edge of the display window 141 to the boundary of the display area 261 is greater than or equal to 0.5 mm, so that the edge of the display layer 26 will expose the display window 141, and further the edge of the display layer 26 will not be observed by the people outside the vehicle 1000, ensuring the appearance of the display glass 10. Along the thickness direction of the display glass 10, the projection of the first part 22 of the flexible substrate 21 is completely located within the projection range of the second shielding layer 15, so that the second shielding layer 15 can completely shield the structure of the flexible display film layer 2 inside the glass body 1, preventing the people inside the vehicle 1000 from observing the structure of the flexible display film layer 2, and also ensuring the appearance of the display glass 10.

[0085] Along the extension direction of the display glass 10, there is a certain distance between the display layer 26 and the outer side surface 103 of the glass body 1, and the distance D is greater than or equal to 3 mm, so that the adhesive layer 12 located between the display layer 26 and the outer side surface 103 of the glass body 1 has a sufficient length, ensuring the sealing effect of the adhesive layer 12 on the display layer 26, so as to prevent moisture from easily entering through the gap between the adhesive layer 12 and the first part 22 and affecting the display effect of the display layer 26.

[0086] It should be noted that the number of electrode layers 25 can be one or more. The number of display layers 26 can be one or more. The number of color filters 27 can be one or more. The corresponding relationship between the numbers of the electrode layer 25, the display layer 26, and the color filter 27 can be freely combined according to the display requirements. For example, when the number of electrode layers 25 is one, in the case where the display glass 10 needs to centrally display a decorative pattern, the number of display layers 26 can be one, and one said display layer 26 and one said electrode layer 25 are stacked; or, the number of display layers 26 can be multiple, and multiple said display layers 26 are all stacked and connected to one said electrode layer 25, and multiple said display layers 26 are spaced along the extending direction of the electrode layer 25. When the number of electrode layers 25 is multiple, multiple electrode layers 25 are spaced along the extending direction of the flexible substrate 21, and the number of display layers 26 is also multiple, and each said display layer 26 and one said electrode layer 25 are stacked. When the number of display layers 26 is one, the number of color filters 27 can be one, and one said color filter 27 completely covers and connects to one said display layer 26. When the number of display layers 26 is multiple, the number of color filters 27 can be one, and one color filter 27 completely covers and connects multiple said display layers 26; or, the number of color filters 27 can be multiple, and each color filter 27 completely covers and connects to one said display layer 26, etc.

[0087] As Figure 3 shown, in this embodiment, the number of display films 24 is two, and the number of display windows 141 is two. Each said display film 24 corresponds to one display window 141, ensuring that people outside the vehicle 1000 can observe the decorative pattern displayed by one said display film 24 through one display window 141. The electrode layer 25 of each display film 24 corresponds to one display layer 26 and one color filter 27. That is, one display film 24 includes one electrode layer 25, one display layer 26, and one color filter 27. The electrode layer 25 of one of the two display films 24 has two first sub-layers 251, and each first sub-layer 251 has one through hole 253, and each through hole 253 is used for a trace 28 connected to the first sub-layer 251 to pass through. In one implementation, the two traces 28 respectively connected to the two first sub-layers 251 can be connected in series to realize the simultaneous control of the two display partitions 262 of the display layer 26 of this display film 24. In another implementation, the two traces 28 connected to the two first sub-layers 251 can be connected in parallel to realize the independent control of the two display partitions 262 of the display layer 26 of this display film 24.

[0088] The other of the two shows that the electrode layer 25 of the display film 24 has a first sub-layer 251, and the first sub-layer 251 has a through-hole 253 for a trace 28 connected to the first sub-layer 251 to pass through. In one implementation, three traces 28 respectively connected to the first sub-layers 251 in the two electrode layers 25 can be connected in series to achieve simultaneous control of three display partitions 262 of the two display layers 26. In another implementation, three traces 28 respectively connected to the first sub-layers 251 in the two electrode layers 25 can be connected in parallel to achieve independent control of three display partitions 262 of the two display layers 26. In yet another implementation, three traces 28 respectively connected to the first sub-layers 251 in the two electrode layers 25 can be partially connected in series or in parallel to achieve partial simultaneous control and partial independent control of three display partitions 262 of the two display layers 26. This application does not make any requirements in this regard.

[0089] To more clearly show the decorative pattern displayed by the flexible display film layer 2, the following takes Figure 6 and Figure 7 an example of a flexible display film layer 2 shown as an example, and combines it with Figure 3 for description. Among them, Figure 6 is Figure 2 a perspective structural schematic diagram of an example for the display glass of the edge wrapping assembly shown to perform display, Figure 7 and Figure 6 is a perspective structural schematic diagram of the flexible display film layer in the edge wrapping assembly shown. The decorative pattern displayed by the display glass in the edge wrapping assembly is actually not limited to the shape shown in Figure 6 . Figure 6 The two kinds of diagonal hatching in Figure 7 respectively represent color filters of two different colors, and the grid-like hatching represents the display pattern of the display film.

[0090] In this embodiment, the display glass 10 includes a plurality of display films 24. According to the general shape of the plurality of display films 24, the plurality of display films 24 include a plurality of first display films 24a and second display films 24b. The plurality of first display films 24a and the second display films 24b are arranged at intervals, and both the first display film 24a and the second display film 24b are connected to the first bearing surface 211 of the flexible substrate 21. The plurality of first display films 24a are arranged at intervals along the length direction of the display glass 10. The second display film 24b is surrounded by the plurality of first display films 24a, which can also be understood as the second display film 24b being embedded in the plurality of first display films 24a. The decorative patterns displayed by the first display film 24a and the second display film 24b are different, and the plurality of first display films 24a and the second display films 24b can be controlled simultaneously or individually to meet the display requirements in different scenarios. In some embodiments, the decorative patterns displayed by the first display film 24a and the second display film 24b can also be the same.

[0091] Each first display film 24a includes a first electrode layer and a first display layer 26a. The structure and connection relationship of the first electrode layer and the first display layer 26a can refer to the structure and connection relationship of the display film 24 described above, which will not be elaborated here. The plurality of first display films 24a include a first color filter 27a, and the first color filter 27a completely covers and is connected to the plurality of first display layers 26a. That is, the plurality of first display films 24a share one color filter 27. The first display layer 26a includes a first display area 261a, and the decorative patterns displayed by the first display areas 261a of the plurality of first display layers 26a can be the same or different. In this embodiment, the shape of the first display layer 26a is generally rectangular. The first display area 261a is generally strip-shaped, and the plurality of first display areas 261 are arranged at intervals along the length direction of the flexible display film layer 2. The first color filter 27a is generally strip-shaped and arc-shaped. In some embodiments, the shapes of the first display layer 26a, the first display area 261a, and the first color filter 27a can be flexibly set according to different display requirements of the flexible display film layer 2, rather than being limited to Figure 6 and Figure 7 the shapes shown, so as to enhance the sense of luxury of the decorative patterns displayed by the display glass 10 and meet the application of the display glass 10 in a variety of scenarios. In some embodiments, the first color filter 27a can be divided into a plurality of small-sized color filters according to the position and shape of each first display layer 26a, and each color filter completely covers and is connected to a first display layer 26a.

[0092] The second display film 24b includes a second electrode layer, a second display layer 26b, and a second color filter 27b. For the structure and connection relationship of the second electrode layer and the second display layer 26b, reference can be made to the structure and connection relationship of the display film 24 described above, which will not be elaborated here. The second color filter 27b completely covers and is connected to the second display layer 26b. The second display layer 26b includes a second display area 261b, and the decorative pattern displayed in the second display area 261b can be the same as or different from the decorative patterns displayed in the plurality of first display areas 261a. In this embodiment, the shape of the second display layer 26b is generally in the shape of an "A". The shape of the second display area 261b is generally in the shape of an "A". The shape of the second color filter 27b is generally triangular. The second display layer 26b is embedded in the first display film 24a. In some embodiments, the shapes of the second display layer 26b, the second display area 261b, and the second color filter 27b can be flexibly set according to different display requirements of the flexible display film layer 2, rather than being limited to Figure 6 and Figure 7 the shapes shown, thereby enhancing the sense of luxury of the decorative patterns displayed on the display glass 10 and meeting the applications of the display glass 10 in various scenarios.

[0093] In this embodiment, the number of display windows 141 of the display glass 10 is the same as that of the display film 24, and there are also multiple of them. The multiple display windows 141 include multiple first display windows 141a and second display windows 141b. The multiple first display windows 141a and the second display windows 141b are arranged at intervals. The multiple first display windows 141a are arranged at intervals along the length direction of the display glass 10. The second display window 141b is surrounded by the multiple first display windows 141a. It can also be understood that the second display window 141b disconnects some of the first display windows 141a. In this embodiment, the first display window 141a is generally a rectangular window. The second display window 141b is generally an "A"-shaped window.

[0094] In this embodiment, along the thickness direction of the display glass 10, the first display film 24a is opposite to and spaced apart from the first display window 141a, and the projection of the first display window 141a is completely within the projection range of the first display area 261a. The distance L1 from the projection edge of the first display window 141a to the boundary of the first display area 261a is greater than or equal to 0.5 mm. The first display window 141a not only ensures that the decorative pattern displayed in the first display partition 262 can be observed by the people outside the vehicle 1000, but also prevents the people outside the vehicle 1000 from observing the edge of the first display layer 26a, ensuring the appearance of the display glass 10.

[0095] Along the thickness direction of the display glass 10, the second display film 24b is disposed opposite to and spaced apart from the second display window 141b. The projection of the second display window 141b is completely within the projection range of the second display area 261b. The distance L2 from the projection edge of the second display window 141b to the boundary of the second display area 261b is greater than or equal to 0.5 mm. The second display window 141b not only ensures that the decorative pattern displayed in the second display partition 262 can be observed by the people outside the vehicle 1000, but also prevents the people outside the vehicle 1000 from observing the edge of the second display layer 26b, thus ensuring the appearance of the display glass 10.

[0096] In the related art, there are existing vehicles that use multi-color inks or mirror inks to form decorative patterns on window glass. The decorative patterns formed in this way have a single shape and a single color and cannot achieve the effect of changing the decorative pattern. Therefore, this decorative method cannot be used in scenarios where the window glass needs to be diversely displayed. In addition, there are also existing vehicles that decorate window glass by integrating decorative pattern-like decorative parts and lighting components. The decorative parts can be aluminum decorative parts, plastic decorative parts, etc. The lighting components can achieve dynamic changes in the decorative pattern. However, the installation process of this method is complex, and the displayed decorative pattern is too fancy, making it difficult to achieve a simple and high-class display effect. At the same time, the brightness of the lighting components in this method is high and they cannot be displayed during driving, so their usage scenarios are also limited.

[0097] In the embodiment of the present application, the display glass 10 of the edge assembly 100 integrates a flexible display film layer 2. The display layer 26 in the flexible display film layer 2 includes a plurality of display partitions 262. Corresponding to each display partition 262, a first sub-layer 251 of an electrode layer 25 is connected. Each first sub-layer 251 is connected to a trace 28. All the traces 28 are connected to a controller 29. The traces 28 can be connected in series or in parallel. When the controller 29 is powered on, the controller 29 can separately control or simultaneously control the display partitions 262 to display different or the same decorative patterns through the traces 28, and realize the color change of the decorative pattern through different color filters, avoiding the single color and single shape of the decorative pattern displayed on the display glass 10, and also avoiding the overly fancy decorative pattern displayed by using lighting components, achieving a simple and high-class display effect of the display glass 10. At the same time, according to the display needs, dynamic changes of the decorative pattern can also be realized; thereby meeting the diverse display requirements of the display glass 10 and realizing display in different scenarios. At the same time, the flexible display film layer 2 can set the number, position, and shape of the display layer 26, color filter 27, and electrode layer 25 according to the display requirements. For example, a plurality of display layers 26 are spaced apart, so that the display glass 10 can save the materials required for display to a certain extent while meeting the display requirements.

[0098] Moreover, the area of the display window 141 is smaller than the area of the display region 261 of the display layer 26. That is, the cutting edge of the display layer 26 can be blocked by the display window 141 of the first shielding layer 14. While ensuring that the decorative pattern can be observed by the people outside the vehicle 1000, it can also prevent the people outside the vehicle 1000 from observing the edge of the display layer 26, thus ensuring the appearance of the display glass 10.

[0099] In the embodiment of the present application, the display glass 10 uses the flexible display film layer 2 to display the decorative pattern. Compared with the prior art in which the decorative parts integrated with decorative patterns and the lighting components are used for decoration, the brightness of the decorative pattern displayed in the embodiment of the present application is low, enabling the display function of the display glass 10 to be used during driving, breaking through the limitation that the display glass 10 cannot be displayed during driving, and expanding the application scenarios of the display glass 10.

[0100] The embodiments of the present application have been introduced in detail above. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
