[0039] In one embodiment, Figure 1 and Figure 2 As shown, the present application proposes a sunshade curtain, comprising: a base fabric layer 110, a flexible display layer 120 and a curtain layer 130 stacked in sequence, the base fabric layer 110 and the flexible display layer 120, as well as the flexible display layer 120 and the curtain layer 130 are bonded by an adhesive layer 140, the flexible display layer 120 comprises: a flexible substrate layer 121, a flexible conductive layer 122 and a light-emitting element 123, the flexible conductive layer 122 is arranged on the surface of the flexible substrate layer 121, the light-emitting element 123 is electrically connected to the flexible conductive layer 122, and the flexible conductive layer 122 is provided with a display connection terminal 124, which is used to connect to a display driving circuit.

[0040] Specifically, the base fabric layer 110 is the basic support layer that supports the entire structure. It can provide mechanical support for the flexible display layer 120. At the same time, the base fabric layer 110 also has the function of shielding external sunlight. It is arranged on the outermost layer of the sunshade. The base fabric layer 110 can be densely woven with dark silk threads. It can use high-strength and weather-resistant textile materials, such as polyester fiber or nylon material, to ensure the durability and stability of the sunshade. In some embodiments, the transmittance of the base fabric layer 110 to visible light is less than or equal to 1%. Preferably, the transmittance of the base fabric layer 110 to visible light is less than or equal to 0.1%.

[0041] The flexible display layer 120 is bonded to the base fabric layer 110 via the adhesive layer 140. The flexible display layer 120 is a display layer with bendable properties. Figure 2As shown, the flexible display layer 120 includes a flexible substrate layer 121, a flexible conductive layer 122, and a light-emitting element 123. The flexible substrate layer 121 can be made of an ultra-thin, bendable plastic or polymer material, such as polyimide (PI) or polyethylene terephthalate (PET), to ensure the flexibility and bendability of the flexible display layer 120. The flexible conductive layer 122 is disposed on the surface of the flexible substrate layer 121 and can be directly bonded to the flexible substrate layer 121 by coating it with a conductive material (e.g., physical vapor deposition or electroless plating). The conductive material can be a metal (e.g., silver, copper, gold), a metal oxide (e.g., indium tin oxide), or a carbon material (e.g., carbon nanotubes). In some embodiments, the flexible conductive layer 122 is provided in the form of silver nanowires or a metal mesh. The sheet resistance of the flexible conductive layer 122 is typically less than 10 to 0.01 Ω / s. It is understood that to achieve electrical connection and independent control of the light-emitting element 123, it is generally necessary to form a specific conductive pattern on the flexible conductive layer 122 through processes such as chemical etching and laser ablation. The flexible conductive layer 122 is also provided with a display connection terminal 124, which is an electrical connection port (such as a gold finger) extending from the flexible conductive layer 122 and is used to connect to an external display driver circuit.

[0042] The light-emitting element 123 is electrically connected to the flexible conductive layer 122 and can be composed of multiple LED (Light-Emitting Diode) chips. The light-emitting element 123 is electrically connected to the flexible conductive layer 122 through methods such as die bonding or reflow soldering. The light-emitting element 123 can be a single-color LED or chip, or a three-color RGB LED. The chips in the light-emitting element 123 can be arranged randomly to simulate a starry night sky, or they can be arranged to form letters, numbers, or graphics. Controlled by the display driver circuit, these letters, numbers, or graphics can be easily altered, such as changing from 0 to 9, switching between different capital letters, the gradual change of the moon from crescent to full, a shooting star streaking across the sky, or the shifting or rotating constellations in the sky.

[0043] The ply 130 is bonded to the flexible display layer 120 via an adhesive layer 140. The ply 130 is the innermost layer of the sunshade curtain, primarily protecting it from scratches, dirt, and moisture. It covers the entire base fabric layer 110, completely enclosing the flexible display layer 120. In some embodiments, coatings may be added to the inner and outer surfaces of the ply 130 to enhance the curtain's summer insulation, winter warmth, and anti-mirror reflection properties. To prevent the ply 130 from interfering with the luminous display of the flexible display layer 120, it must have a high visible light transmittance. In some embodiments, the visible light transmittance of the ply 130 is greater than or equal to 50%. In one embodiment, the ply 130 is coated with a polymer. The polymer can be applied to the surface of the ply 130 through methods such as hot pressing, gluing, or coating to enhance its ability to block moisture, dirt, and scratches. In one embodiment, the carcass layer 130 is a polymer layer, that is, the carcass layer 130 is entirely composed of a polymer. The polymer can be made of PET, PC, PVC, polyvinyl fluoride, or other materials.

[0044] The bonding layer 140 between the base fabric layer 110 and the flexible display layer 120, and between the flexible display layer 120 and the curtain fabric layer 130 can be a hot melt adhesive, a water-based adhesive, etc., which is completed by stacking multiple layers of materials in a mold and then bonding them by hot pressing or cold pressing.

[0045] The sunshade of the embodiment of the present application can be an independent component or integrated into a vehicle. The flexible substrate layer 121 allows the entire flexible display layer 120 to curl and deform with the sunshade to meet the needs of rolling up and storing the vehicle sunshade. The combined structure of the flexible substrate layer 121 and the adhesive layer 140 enables the flexible display layer 120 to maintain the stability of the circuit connection during repeated curling. Moreover, through the integrated design of the flexible conductive layer 122 and the light-emitting element 123, each light-emitting element 123 can be driven individually, supporting the display of differentiated content in different areas, thereby completing the real-time dynamic control of the light-emitting element 123, enriching the dynamic change effect of the sunshade and further enhancing the atmosphere inside the vehicle.

[0046] In some embodiments, as Figure 3 As shown, the flexible conductive layer 122 can also be bonded to the flexible substrate layer 121 through an additional adhesive layer 125. In some embodiments, as shown in FIG. Figure 4As shown, to improve reliability and avoid excessive exposure of the flexible conductive layer 122, the upper and lower sides of the portion of the flexible conductive layer 122 that is not directly connected to the light-emitting element 123 can be wrapped with an adhesive layer 125, exposing only the portion of the flexible conductive layer 122 that needs to be directly connected to the light-emitting element 123 to supply power to the light-emitting element 123. In some embodiments, in order to achieve independent control of more components and more complex functions, a multi-layer stacking structure of multiple adhesive layers 125 and multiple conductive layers can be provided to form a multi-layer wiring. For example, Figure 5 As shown, the adhesive layer 125 and the flexible conductive layer 122 are both configured as a five-layer structure, interlaced with each other to achieve independent control of more light-emitting elements 123. It will be appreciated that the material of the adhesive layer 125 can be selected based on the properties of the flexible conductive layer 122 and the flexible substrate layer 121. The material of the adhesive layer 125 can be polyurethane, epoxy resin, polydimethylsiloxane (PDMS), polyimide (PI), etc.

[0047] In one embodiment, Figure 6 As shown, the sunshade curtain also includes: a flexible touch layer 150, which is arranged between the flexible display layer 120 and the curtain layer 130, and the flexible touch layer 150 and the flexible display layer 120, and the flexible touch layer 150 and the curtain layer 130 are bonded by an adhesive layer 140, and the flexible touch layer 150 is provided with a touch connection terminal 151, which is used to connect to the touch detection circuit.

[0048] Specifically, the flexible touch layer 150 is a flexible structural layer with touch functionality. It can be implemented using a capacitive touch film, generating a corresponding touch signal by detecting changes in capacitance at the touch location. The touch connector 151 is an interface for connecting to an external touch detection circuit. It can be implemented using a conductive silver printed circuit or a flexible printed circuit (FPC). Touch connector 151 transmits the touch signal to the touch detection circuit for processing. The flexible touch layer 150 is integrated between the flexible display layer 120 and the fabric layer 130, secured to the flexible display layer 120 and the fabric layer 130 by upper and lower adhesive layers 140, respectively, to form a laminated structure. When a user touches the surface of the fabric layer 130, the flexible touch layer 150 detects the touch location and generates an electrical signal. This signal is transmitted to the external touch detection circuit via the touch connector 151, enabling touch command recognition and response. For example, when a user touches a certain position of the curtain layer 130, the flexible touch layer 150 at the corresponding position will be triggered. At this time, after being processed by the external control circuit, the display control circuit controls the light-emitting element 123 at the corresponding position in the flexible display layer 120 to emit light and display; or the sunshade can be retracted or extended by touching a specific position. The additional provision of the flexible touch layer 150 does not affect the curling or unfolding action of the sunshade, and the stability of the interlayer structure can be maintained by the adhesive layer 140. By adding the flexible touch layer 150, this embodiment allows the sunshade to expand the touch operation function based on the display, solving the problem of the single dynamic interaction method in the existing technology and improving the user interaction experience.

[0049] In one embodiment, Figure 7 As shown, the flexible touch layer 150 includes: a flexible base layer 152, a first conductive layer 153, a second conductive layer 154 and an insulating layer 155. The first conductive layer 153 is arranged on one side of the flexible base layer 152, and the insulating layer 155 is arranged between the first conductive layer 153 and the second conductive layer 154. The first conductive layer 153 and the second conductive layer 154 are both electrically connected to the touch connection end 151.

[0050] Specifically, the flexible base layer 152 is a flexible material layer used to support the conductive layer. It can be made of polyimide (PI) or polyethylene terephthalate (PET), among others. It provides structural support and bending properties for the flexible touch layer 150. The first conductive layer 153 is a conductive structural layer disposed on one side of the flexible base layer 152. It can be implemented using an indium tin oxide coating or a metal mesh coating. It detects touch positions through changes in electrical signals. The second conductive layer 154 is a conductive structural layer spaced apart from the first conductive layer 153. It can be implemented using the same material or a different material. It cooperates with the first conductive layer 153 to form an electrode pair for touch detection. The insulating layer 155 is a non-conductive material layer disposed between the first and second conductive layers 153, 154. It physically isolates the two conductive layers from each other to prevent short circuits. The touch connection terminals 151 are electrically connected to the first and second conductive layers 153, 154, respectively. When a user touches the surface of the curtain ply 130, the touch causes a capacitance change between the two conductive layers at the contact point. The touch detection circuit collects this capacitance change signal through the touch connector 151 and calculates the touch coordinates. This embodiment achieves high-precision touch positioning while maintaining the flexibility of the sunshade by utilizing the spatial isolation and signal coordination of the double-layer conductive structure. Furthermore, the centralized wiring design of the touch connector 151 reduces circuit complexity and signal interference.

[0051] In one embodiment, Figure 8 As shown, the sunshade also includes: a decorative layer 160, which is arranged between the flexible display layer 120 and the curtain layer 130, and the decorative layer 160 includes: a light-transmitting area and a non-light-transmitting area, and the light-transmitting area is aligned with or smaller than the display area of the flexible display layer 120.

[0052] Specifically, such as Figure 8As shown, when only the flexible display layer 120 is provided, the flexible display layer 120 and the decorative layer 160 are bonded via the adhesive layer 140. The decorative layer 160 and the fabric ply 130 can be directly bonded via a polymer. The flexible display layer 120 is divided into a central display area and surrounding functional areas. The functional areas surrounding the flexible display layer 120 contain some opaque or poorly-appearing areas due to process requirements, such as alignment marks around the diaphragm, the diaphragm serial number, and low-resistance traces near the FPC bonding area. These opaque or poorly-appearing areas need to be shielded from user observation, thereby improving the user experience. This embodiment provides a decorative layer 160 between the flexible display layer 120 and the fabric ply 130. The decorative layer 160 comprises a translucent area and a non-translucent area. The central area of the decorative layer 160 is generally translucent, while the surrounding areas are generally non-translucent. In some embodiments, the visible light transmittance of the light-transmitting area of the decorative layer 160 is greater than or equal to 10%. Preferably, the visible light transmittance of the light-transmitting area of the decorative layer 160 is greater than or equal to 30%. In some embodiments, the visible light transmittance of the non-light-transmitting area is less than or equal to 1%. In some embodiments, the flexible display layer 120 and the decorative layer 160 are transparent or black, or a color similar to that of the carcass ply 130. The light-transmitting area of the decorative layer 160 can also be configured with a specific color, texture, or pattern to match the vehicle interior. The transmittance of the textured or patterned areas of the light-transmitting area of the decorative layer 160 can be equal to or less than the transmittance of the non-textured or non-patterned areas of the light-transmitting area. In some embodiments, the light-transmitting area of the decorative layer 160 is aligned with the display area of the flexible display layer 120. In some embodiments, the light-transmitting area of the decorative layer 160 is smaller than the display area of the flexible display layer 120. For example, each side of the light-transmitting area of the decorative layer 160 is indented by 2 to 30 mm. By providing the decorative layer 160, the non-transparent area of the decorative layer 160 can shield the functional area surrounding the flexible display layer 120, while also merging the color and pattern with the central translucent area to ensure consistency in overall appearance. It should be understood that the decorative layer 160 should have the same area and shape as the base fabric layer 110.

[0053] In one embodiment, Figure 9As shown, when the sunshade is provided with both a flexible display layer 120 and a flexible touch layer 150, the flexible touch layer 150 and the decorative layer 160 are bonded via an adhesive layer 140, while the decorative layer 160 and the curtain fabric layer 130 can be directly bonded via a polymer. In this embodiment, the touch layer also includes a central light-transmitting area and surrounding functional areas. In some embodiments, the central light-transmitting area of the touch layer is aligned with the central display area of the flexible display layer 120. In some embodiments, the central light-transmitting area of the touch layer is larger than the central display area of the flexible display layer 120. For example, the central light-transmitting area of the touch layer is set to be 5 mm larger than the central display area boundary of the display layer. In this case, if the light-transmitting area of the decorative layer 160 is aligned with or smaller than the display area of the flexible display layer 120, the non-light-transmitting area of the decorative layer 160 can shield the functional areas surrounding the flexible display layer 120 and the flexible touch layer 150, while also merging with the central light-transmitting area in color and pattern to ensure consistency in the overall appearance.

[0054] In one embodiment, Figure 10 As shown, the sunshade further includes: a winding core 170 and a traction member 180 , and the winding core 170 and the traction member 180 are respectively arranged at two ends of the base fabric layer 110 .

[0055] Specifically, the winding core 170 is a cylindrical structure used to roll up the sunshade. It can be a hollow metal tube or a plastic tube with a non-slip coating. A torsion spring can be installed inside it to allow the base fabric layer 110 to be wound and unwound. The traction member 180 is a traction structure connected to the end of the base fabric layer 110. It can be configured as a beam. The traction member 180 applies tension to keep the base fabric layer 110 flat when unwound. In some embodiments, the sunshade can be opened and closed by a motor-controlled traction member 180. The motor drives the flexible shafts on both sides of the sunshade to operate synchronously. The buckles at the front of the flexible shafts assemble with the sliders at both ends of the traction member 180 and drive them together, pushing the traction member 180 forward and pulling the sunshade rolled onto the winding core 170, thereby opening the sunshade. To close the sunshade, the motor reverses, driving the slider and traction member 180 to retract under the flexible shafts. Simultaneously, the sunshade can be retracted onto the winding core 170 by the torsion springs within the winding core 170. In some embodiments, the display connection terminal 124 is positioned near the end of the winding core 170, and the display connection terminal 124 protrudes from the base fabric layer by 10 mm or more. The display connection terminal 124 can be integrated into the wire groove inside the winding core 170 to ensure that the conductive circuit connected to the display connection terminal 124 is properly connected during the winding process. Figure 10 In the flexible display layer 120, the light-emitting chips in the light-emitting element 123 are arranged irregularly, which can simulate the stars at night.

[0056] In one embodiment, Figure 11As shown, when the sunshade is provided with both a flexible display layer 120 and a flexible touch layer 150, the winding core 170 and the traction member 180 are respectively arranged at both ends of the base fabric layer 110. In some embodiments, the display connection terminal 124 and the touch connection terminal 151 are both arranged at one end near the winding core 170, and both the display connection terminal 124 and the touch connection terminal 151 extend greater than or equal to 10 mm beyond the base fabric layer 110. The display connection terminal 124 and the touch connection terminal 151 can be integrated into the wire groove inside the winding core 170, ensuring that the conductive circuits connected to the display connection terminal 124 and the touch connection terminal 151 are properly connected during the winding process. Figure 11 In the flexible display layer 120, the light-emitting chips in the light-emitting element 123 are arranged into certain letters, numbers or graphics. Through the control of the display driving circuit, simple changes of letters, numbers and graphics can be realized, such as the change of numbers from 0 to 9, the switching of different capital letters, and the meteor across the sky. In one embodiment, Figure 12 As shown, the light-emitting chips in the light-emitting element 123 of the flexible display layer 120 are arranged in an array at a fixed pitch (e.g., 1-5 mm). The display control circuit controls the light-emitting chips in different rows and columns to emit light of different colors, thereby displaying various types of images.

[0057] In one embodiment, Figure 13 As shown, a sealant 126 is provided at the connection between the light-emitting element 123 and the flexible conductive layer 122. Specifically, during the rolling motion of the sunshade, the base fabric layer 110 is subjected to a certain degree of traction, causing elastic deformation. The light-emitting element and the flexible conductive layer 122 are connected only via solder pads of limited area (typically less than 1 mm x 1 mm). When the base fabric layer 110 is subjected to traction and elastic deformation, the flexible display layer 120, the curtain layer 130, the adhesive layer 140, and other layers are also deformed due to the applied force. At this time, the difference in deformation between the various material layers causes a certain degree of shear force to be applied to the solder pads between the light-emitting element and the flexible conductive layer 122. High shear force can quickly destroy the electrical connection between the light-emitting element and the flexible conductive layer 122, causing functional failure. Even low shear force, repeated application over a long period of time can cause the same detrimental effects. To minimize the reliability risks associated with shear force, this embodiment reinforces the light-emitting element by providing a sealant 126 around the light-emitting element. The sealant 126 can be made of UV-cured acrylic resin, epoxy resin, polyurethane glue, silicone resin, etc. In this embodiment, by providing the sealant 126, in addition to reducing the risk of the light-emitting body falling off, it can also prevent the erosion of harmful substances such as external water vapor, thereby improving the reliability of the light-emitting body in various extreme environments.

[0058] In one embodiment, Figure 14As shown, the flexible display layer 120 includes multiple sub-display layers 210, and the display connection end 124 includes multiple sub-connection ends 220. Each sub-display layer 210 is provided with a corresponding sub-connection end 220. Specifically, when the base fabric layer 110 is large in size, a single sub-display layer 210 cannot cover all areas that need to be illuminated. In this case, multiple sub-display layers 210 can be spliced together to complete a large-size display. Figure 14 As shown, the flexible display layer 120 is spliced together by four sub-display layers 210, and correspondingly, the display connection end 124 includes four sub-connection ends 220. It can be understood that the structure of the sub-display layer 210 is the same as the structure of the flexible display layer 120 in the above embodiment, and will not be repeated here. In some embodiments, when the sunshade is provided with a decorative layer 160, the non-light-transmitting area of the decorative layer 160 can cover the splicing gaps between the multiple sub-display layers 210. The shape of the spliced flexible display layer 120 is determined by the sub-display layer 210, and the shape and size of the sub-display layer 210 can be set arbitrarily. Figure 15 As shown, the sub-display layer 210 is configured as a long strip, and the light-emitting elements 123 on a sub-display are arranged in a straight line. Each sub-display is connected to a corresponding sub-connection terminal 220, which is connected to the conductive layer in the sub-display. By splicing and combining multiple sub-displays, a large-scale light-emitting display can be achieved.
