[0014] Optionally, the display mechanism further includes a controller for communicating with the display layer, and a light sensor for communicating with the controller or the vehicle's infotainment system; the controller is used for communicating with at least one of the infotainment system and the mobile terminal.

[0015] To address the aforementioned problems, the present invention also provides an intelligent display skylight, comprising a skylight body and a display mechanism as described above, wherein the display mechanism is disposed on the skylight body.

[0016] To address the above problems, the present invention also provides a method for manufacturing a display mechanism, applicable to manufacturing the display mechanism described above, comprising:

[0017] The optical modulation layer, the conductive substrate layer, and the display layer are stacked and connected in sequence to obtain the display mechanism.

This reduces the impact of the display mechanism on the vehicle's interior space and improves the user's driving experience. Additionally, the display mechanism is positioned on the side of the sunroof facing the vehicle interior to avoid potential damage from prolonged exposure to the external environment, thus extending its lifespan.

[0030] Figure 3 This is a schematic diagram of a sub-process of step 100 in an embodiment of the present invention. Detailed Implementation

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Combination Figure 1As shown, an embodiment of the present invention provides a display mechanism applied to a vehicle, the display mechanism comprising:

[0033] An optical modulation layer, wherein at least one of its transparency and transmittance is suitable for adjustment;

[0034] The display layer is used to display the corresponding content;

[0035] A conductive substrate layer, which is used to power the display layer;

[0036] An optical modulation layer, a conductive substrate layer, and a display layer are stacked sequentially. The side of the optical modulation layer facing away from the conductive substrate layer is used to connect with the side of the sunroof body facing the interior of the vehicle.

[0037] In this embodiment, the display mechanism is installed (or set) on the sunroof body of the vehicle's sunroof to display corresponding content (such as text, images, animations, videos, etc.) at the sunroof body location, satisfying users' personalized and customized needs for image display on the car sunroof. The sunroof is divided into two types: openable and closable sunroofs (i.e., closed sunroofs). The sunroof body is the light-transmitting component of the sunroof (such as a light-transmitting component made of glass or other materials). The sunroof body serves as the carrier of the display mechanism on the vehicle, used for its installation or setting.

[0038] Specifically, the display mechanism includes an optical modulation layer, a conductive substrate layer, and a display layer. The display layer displays relevant content to meet user needs for image display on the car sunroof. The conductive substrate layer powers the display layer and provides protection and support for the display layer and other components of the display mechanism, ensuring the overall stability and reliability of the display layer and the display mechanism. The conductive substrate layer contains circuits for powering the display layer and related devices, and for signal transmission, ensuring stable operation of the display mechanism, i.e., ensuring normal light emission or display. At least one of the transparency and transmittance of the optical modulation layer is adjustable, allowing adjustment of the light passing through the optical modulation layer from inside and outside the vehicle, thereby optimizing the overall display effect and improving the user experience.

[0039] For the display mechanism, the optical modulation layer, conductive substrate layer, and display layer are stacked sequentially to ensure a large contact area between the optical modulation layer and the conductive substrate layer, as well as between the conductive substrate layer and the display layer. This facilitates stable bonding between the optical modulation layer, conductive substrate layer, and display layer, thereby improving the stability of the connection between them and ensuring the stability and reliability of the display mechanism's operation. Regarding the connection between the display mechanism and the vehicle's sunroof body, the display mechanism is preferably located on the inner side of the sunroof body (i.e., the side of the sunroof body facing the vehicle interior) to avoid potential damage from long-term exposure to the external environment. Correspondingly, the side of the optical modulation layer facing away from the conductive substrate layer is used to connect with the side of the sunroof body facing the vehicle interior. In other words, in the direction from the sunroof body towards the vehicle interior (or vehicle cabin), the sunroof body, optical modulation layer, conductive substrate layer, and display layer are connected sequentially. The transparency and / or transmittance of the optical modulation layer are adjustable. By adjusting at least one of the transparency and transmittance of the optical modulation layer, the intensity and direction of light passing through it can be changed, thereby regulating the light entering the vehicle from outside through the sunroof and adjusting the display effect of the display mechanism to ensure optimal display of the corresponding content and the best viewing experience for the user. Alternatively, when the display mechanism is not needed to display the corresponding content, adjusting the transparency and / or transmittance of the optical modulation layer can achieve shading (corresponding to lower transparency and / or transmittance, acting as a sunshade or protecting privacy) or enhance the sunroof viewing experience (corresponding to higher transparency and / or transmittance). Accordingly, the conductive substrate layer uses a (high) transparency material to ensure that light can pass through effectively, ensuring the viewing experience for the user inside the vehicle through the sunroof when the transparency and transmittance of the optical modulation layer are high. In some embodiments, the display mechanism also needs to adopt a structure with high transparency (when no content is displayed) to ensure that the sunroof viewing experience can be enhanced by increasing the transparency and / or transmittance of the optical modulation layer when no content is displayed.

[0040] Thus, in this embodiment, a display mechanism is installed on the sunroof body of the vehicle to display the corresponding content required by the user, thereby satisfying the user's functional needs for image display and other functions of the car (or vehicle) sunroof. Specifically, the display mechanism displays the corresponding content by setting a display layer to meet the user's image display needs for the car sunroof; by setting a conductive substrate layer, it provides power supply, protection, and support for the display layer of the display mechanism, ensuring stable operation of the display mechanism and ensuring the overall stability and reliability of the display layer and the display mechanism; by setting at least one optical modulation layer with adjustable transparency and transmittance, the light passing through the optical modulation layer inside and outside the vehicle can be adjusted by adjusting the transparency and / or transmittance of the optical modulation layer, thereby adjusting the overall display effect of the display mechanism, optimizing the overall display effect of the display mechanism, and improving the user experience. Furthermore, the optical modulation layer, conductive substrate layer, and display layer are stacked sequentially. On one hand, this enhances the stability of the connection between these layers, ensuring stable operation of the display mechanism. On the other hand, the stacked arrangement facilitates a thinner design for the display mechanism, keeping the overall thickness of the display mechanism and the sunroof using it extremely thin. This reduces the impact of the display mechanism on the vehicle's interior space and improves the user's driving experience. Additionally, the display mechanism is positioned on the side of the sunroof facing the vehicle interior to avoid potential damage from prolonged exposure to the external environment, thus extending its lifespan.

[0041] Optionally, the optical modulation layer can be used to adjust optical parameters such as transparency and transmittance, thereby adjusting the light transmittance and reflectivity of the skylight, so that the display effect of the display mechanism can maintain good visibility and clarity under different lighting conditions; the optical modulation layer can also protect the display mechanism, prevent the external environment from affecting the display device, and extend the service life and stability of the display device.

[0042] Optionally, the conductive substrate layer includes a substrate layer and a conductive layer disposed on the substrate layer, and the conductive substrate layer supplies power to the display layer through the conductive layer; the side of the substrate layer away from the conductive layer is connected to the side of the sunroof body facing the vehicle interior through an optical modulation layer, the substrate layer is a transparent component, and the optical modulation layer adopts at least one of a liquid crystal layer, an electrochromic layer, and a photochromic layer.

[0043] In this embodiment, the conductive substrate layer includes a substrate layer and a conductive layer disposed on the substrate layer. The substrate layer serves to connect, protect, and support the display layer and other components of the display mechanism, as well as support the fabrication and operation of subsequent display and conductive layers, ensuring the stability and reliability of the display mechanism's operation. The conductive layer is a structure made of conductive material disposed on the substrate layer for power supply and signal transmission of the display layer and related devices. The substrate layer, conductive layer, and display layer are connected sequentially (stacked) to ensure a stable connection between the conductive substrate layer and the display layer, and to ensure the stable operation of the display layer. Furthermore, the side of the substrate layer facing away from the conductive layer is connected to the side of the sunroof body facing the vehicle interior through an optical modulation layer. In other words, in the direction from which the sunroof body points towards the vehicle interior (or vehicle cabin), the sunroof body, optical modulation layer, substrate layer, conductive layer, and display layer are connected sequentially.

[0044] Moreover, the base layer is a transparent component, that is, the base layer uses transparent materials, such as highly transparent materials, to ensure that light can effectively pass through the base layer, and to ensure that the adjustment of the transparency and / or transmittance of the optical modulation layer itself can directly affect the display layer or the interior of the vehicle, thereby improving the display effect of the display mechanism (or the user's viewing effect) or the sunroof viewing experience. The optical modulation layer employs at least one of a liquid crystal layer (or liquid crystal material), an electrochromic layer (or electrochromic material), and a photochromic layer (or photochromic material) to adjust its transparency and / or transmittance. For example, the optical modulation layer may employ a liquid crystal layer (such as an electronically controlled liquid crystal layer or a polymer-dispersed liquid crystal (PDLC) film) or an electrochromic material to change its transmittance according to changes in electrical signals, controlling the sunroof's light transmittance and thus maintaining a comfortable lighting environment or optimal display environment in different in-vehicle and out-of-vehicle lighting conditions. Alternatively, the optical modulation layer may employ a photochromic material to automatically adjust the sunroof's color and transmittance under different lighting conditions, thereby maintaining a comfortable lighting environment or optimal display environment in different in-vehicle and out-of-vehicle lighting conditions. For instance, when the sunroof needs to display relevant content, the optical modulation layer can be adjusted to a black substrate to minimize the impact of external light on the content display. In some embodiments, the optical modulation layer may employ a film structure to facilitate easy adhesion to the sunroof body and reduce interior space occupation.

[0045] Optionally, the display layer includes one of a self-emissive display layer and a non-self-emissive display layer.

[0046] In this embodiment, the display layer can be a self-emissive display layer for displaying content. This self-emissive display layer (such as OLED or Micro LED, which are self-emissive and do not require a backlight) can emit light independently, without the need for an external light source. Each pixel can independently control its luminous intensity and color, achieving high contrast and vibrant color display. Thus, using a self-emissive display layer eliminates the need for an additional backlight or front light layer, allowing for a thinner, lighter, and more energy-efficient design. Alternatively, the display layer can be a non-self-emissive display layer, such as an LCD (Liquid Crystal Display) or electronic ink technology / electronic ink screen, which does not emit light itself. In some embodiments, non-self-emissive display layers require the use of an external light source (backlight or front light layer) to enhance the viewing experience.

[0047] Optionally, the self-emissive display layer includes multiple light-emitting structures for being disposed at preset designated positions on the conductive layer and electrically connected to the conductive layer; the luminous brightness and luminous color of each light-emitting structure of the self-emissive display layer are suitable for independent control.

[0048] In this embodiment, according to the display requirements of the display layer, for the conductive layer disposed on the substrate layer, a corresponding light-emitting structure is set at a corresponding position on the conductive layer (denoted as a preset designated position), and the conductive layer and the light-emitting structure are electrically connected at that position (preset designated position) to supply power to the light-emitting structure through the conductive layer and to achieve independent control of the light-emitting brightness and color of each light-emitting structure. By setting multiple light-emitting structures, and the light-emitting brightness and color of each light-emitting structure in the self-emissive display layer are suitable for independent control, each light-emitting structure can serve as a pixel for displaying corresponding content on the display layer. In order to achieve the display of various different contents by different combinations of whether the corresponding light-emitting structure is lit, its light-emitting brightness, and its light-emitting color, it is possible to meet the user's image display needs for car sunroofs, etc.

[0049] Optionally, when the display layer is a non-self-emissive display layer, the display mechanism also includes a light source adapted to the non-self-emissive display layer.

[0050] In this embodiment, when the display layer is a non-self-emissive display layer, the user's viewing experience of the display layer is improved by setting a light source adapted to the non-self-emissive display layer. That is, the non-self-emissive display layer (such as a display layer using LCD (Liquid Crystal Display) or electronic ink technology / electronic ink screen, etc.) does not emit light itself and needs to be combined with an external light source (backlight layer or front light layer) to improve the viewing experience. Specifically, if the side of the non-self-emissive display layer facing the user is defined as the front side, and the side away from the user as the rear side, then for the backlight layer and front light layer: the backlight layer is located behind the non-self-emissive display layer, illuminating the non-self-emissive display layer to make the content visible; the front light layer is located in front of the non-self-emissive display layer, providing additional illumination to improve visibility. For example, for a non-self-emissive display layer using an LCD, it emits light in conjunction with a backlight layer to achieve clear visibility of the displayed content; for a non-self-emissive display layer using e-ink technology / e-ink screen, it can be used under natural light, or it can achieve clear visibility of the displayed content in conjunction with a front light layer. For example, in environments with low natural light intensity, the front light layer emits light to achieve clear visibility of the content displayed by the non-self-emissive display layer using e-ink technology / e-ink screen. In some embodiments, the front light layer of the display layer can be used to provide illumination for the vehicle interior, or the vehicle interior lighting fixtures can serve as the front light layer of the display layer.

[0051] Optionally, the display mechanism may also include a touch layer disposed on the side of the display layer opposite to the conductive substrate layer.

[0052] In this embodiment, the touch layer is a layer that senses user touch operations and can employ capacitive or infrared touch technology. For example, when the display mechanism is used to display corresponding content inside the vehicle, after the display mechanism is installed on the sunroof body, the touch layer can be installed on the side of the display mechanism away from the sunroof body (or away from the conductive substrate layer), so that the touch layer is located on the side of the display mechanism facing the vehicle interior (i.e., the side closer to the passenger / user inside the vehicle). This allows the user to control the operating parameters and displayed content of the display mechanism by touching the touch layer. This further enriches the functionality of the vehicle sunroof using the display mechanism and enhances the user's interactive experience. The introduction of the touch layer enables the vehicle sunroof to not only have a display function but also provide an intuitive interactive method. Users can control the content displayed on the sunroof, adjust the brightness, select functions, etc., through touch, improving operational convenience and user experience.

[0053] Optionally, the display mechanism further includes a controller for communicating with the display layer, and a light sensor for communicating with the controller or the vehicle's infotainment system; the controller is used for communicating with at least one of the infotainment system and the mobile terminal.

[0054] In this embodiment, the display mechanism further includes a controller for communicating with the display layer, and the controller is used to communicate with at least one of the vehicle-mounted system and the mobile terminal. Specifically, the controller (or processor) communicates with the display layer (e.g., through corresponding circuitry in the conductive layer), and the display mechanism drives (or controls) the display layer to display corresponding content through the controller. The controller's communication with at least one of the vehicle-mounted system and the mobile terminal enables communication between the display mechanism and at least one of the devices, such as a mobile phone, thereby allowing the vehicle-mounted system or the mobile terminal to transmit the content to be displayed to the display mechanism for display. The controller (or processor) can be a microprocessor, allowing it to be integrated into the display mechanism and reduce the overall space occupied by the display mechanism.

[0055] The display mechanism also includes a light sensor that communicates with the controller or the vehicle's infotainment system. Specifically, the display mechanism further includes a light sensor (such as a photosensor, fiber optic sensor, etc.) that communicates with the controller or the vehicle's infotainment system (which communicates with the controller). This allows the controller or the vehicle's infotainment system to adjust the corresponding operating parameters of the display mechanism based on the light information collected by the light sensor from inside and outside the vehicle, thereby achieving better display or viewing effects. The light sensor is used to collect relevant light information from outside and / or inside the vehicle (such as light intensity, color temperature, and direction of light). In some embodiments, the light sensor may be integrated into the display mechanism (e.g., integrated into the conductive substrate layer of the display mechanism) or be a separate structural element of the display mechanism (i.e., not integrated into the display mechanism but communicating with the controller of the display mechanism).

[0056] Optionally, the controller and light sensor can be integrated onto the conductive substrate layer of the display mechanism. Specifically, the corresponding controller (used to achieve communication connections with other devices and control the display mechanism to display corresponding content, etc.) and sensor (such as a light sensor for collecting and acquiring light information inside and outside the vehicle) are placed on the substrate layer, and power supply and electrical connection with other devices are achieved through the conductive layer. In this way, the controller and light sensor can be used to control the display of the display mechanism and respond to changes in the external environment (such as light information), ensuring that the corresponding parameters of the display mechanism can be accurately adjusted to improve the display effect. For example, the controller (or processor) is mounted on the conductive substrate layer of the display mechanism. It can be reverse-mounted, that is, the pins or pads of the processor chip are directly connected to the corresponding connection points of the conductive layer on the conductive substrate layer; or it can be mounted in the correct position, such as by wire bonding (connecting the pins or connection points of the processor chip to the corresponding connection points of the conductive layer through thin metal wires) to achieve the connection with the conductive layer on the conductive substrate layer.

[0057] Combination Figure 1As shown, another embodiment of the present invention provides an intelligent display skylight, including a skylight body and a display mechanism as described above, wherein the display mechanism is disposed on the skylight body.

[0058] Specifically, by setting (connecting or installing) the above-mentioned display mechanism on the sunroof body, a smart display sunroof is obtained. The smart display sunroof displays corresponding content through the display mechanism. By setting a smart display sunroof on the vehicle, it is used to display the corresponding content (such as text, images, animations, videos, etc.) required by the user, to meet the user's functional needs for image display and other functions of the car (or vehicle) sunroof. For example, the display mechanism is set on the inner side of the sunroof body (i.e., the side of the sunroof body facing the inside of the vehicle) to avoid the possibility of damage to the display mechanism due to long-term exposure to the external environment.

[0059] Another embodiment of the present invention provides a vehicle including the display mechanism as described above, and / or, the intelligent display sunroof as described above.

[0060] In this embodiment, the vehicle uses at least one of the above-mentioned display mechanism and intelligent display sunroof to display the corresponding content required by the user (such as text, images, animations, videos, etc.) to meet the user's functional needs for image display and other functions of the car (or vehicle) sunroof.

[0061] Combination Figure 1 , Figure 2 As shown, another embodiment of the present invention provides a method for manufacturing a display mechanism, comprising:

[0062] Step 200: Stack and connect the optical modulation layer, the conductive substrate layer and the display layer in sequence to obtain the display mechanism.

[0063] Specifically, in step 200, a display mechanism is obtained by sequentially stacking and connecting the optical modulation layer, the conductive substrate layer, and the display layer. The display layer displays relevant content to meet user needs for image display on the sunroof. The conductive substrate layer powers the display layer and provides protection and support for the display layer and other components of the display mechanism, ensuring the overall stability and reliability of the display layer and the display mechanism. At least one of the transparency and transmittance of the optical modulation layer is adjustable to regulate the amount of light passing through it from inside and outside the vehicle, thereby optimizing the overall display effect and improving the user experience. By sequentially stacking and connecting the optical modulation layer, the conductive substrate layer, and the display layer, a thin design of the display mechanism is achieved, allowing the thickness of the entire display mechanism and the sunroof using it to be kept extremely thin, reducing the impact of the display mechanism on the vehicle's interior space and improving the user's driving experience.

[0064] Thus, the method of this embodiment is used to manufacture the display mechanism to obtain the required display mechanism. By setting the display mechanism on the sunroof body of the vehicle to display corresponding content, the user's image display needs for the car sunroof can be met. Specifically, by setting a conductive substrate layer between the optical modulation layer and the display layer, a conductive substrate layer is obtained that serves to connect, protect, support, and supply power to the display layer and other components of the display mechanism. This improves the overall stability and reliability of the display layer and display mechanism, ensuring stable operation of the display mechanism. Especially for vehicles in motion, the conductive substrate layer ensures stable operation of the display mechanism even in bumpy or other adverse vehicle operating environments. By sequentially stacking and connecting the optical modulation layer, the conductive substrate layer, and the display layer, a display mechanism for displaying user-required content is obtained and set on the sunroof body of the vehicle. This enriches the functionality of the vehicle sunroof, meets the user's personalized and customized needs for image display on the car sunroof, and facilitates the thin design of the display mechanism.

[0065] Optionally, step 200 includes:

[0066] An optical modulation layer is prepared, and a display layer is prepared on a conductive substrate layer. The optical modulation layer, the conductive substrate layer, and the display layer are stacked and connected in sequence to obtain a display mechanism; or, the prepared optical modulation layer, the conductive substrate layer, and the prepared display layer are stacked and connected in sequence to obtain a display mechanism.

[0067] Specifically, to enrich the functionality of the display mechanism and the sunroof of the vehicle using the display mechanism, and to optimize the display effect, an optical modulation layer with adjustable transparency and / or transmittance is prepared for use in the display mechanism. Considering that the preparation of the optical modulation layer can be carried out independently, after the preparation of the conductive substrate layer is completed, the display layer can be manufactured (or prepared) on the conductive substrate layer. The corresponding preparation process includes setting the corresponding devices of the display layer on the conductive substrate layer, electrical connection between the display layer and the conductive layer of the conductive substrate layer, and connection between the display layer and the conductive substrate layer; the optical modulation layer, the conductive substrate layer and the display layer are sequentially stacked and connected to obtain the display mechanism. By fabricating the display layer on the conductive substrate, the overall manufacturing process of the display mechanism is tightly integrated, facilitating high-precision alignment and high-quality connection between the conductive substrate and the display layer. This helps to better control the relevant parameters in the production process of the display mechanism, improving product consistency and quality. The sequential stacking and connection of the optical modulation layer, conductive substrate, and display layer facilitates the thin design of the display mechanism, allowing the thickness of the entire display mechanism and the sunroof using the display mechanism to be controlled within an extremely thin range. This reduces the impact of the display mechanism on the vehicle's interior space and enhances the user's driving experience.

[0068] Alternatively, after the conductive substrate layer is prepared, the pre-prepared optical modulation layer, conductive substrate layer, and pre-prepared display layer are sequentially stacked and connected to obtain the desired display mechanism. This allows the manufacturing processes of the conductive substrate layer, optical modulation layer, and display layer to be carried out step-by-step and independently. For example, the manufacturing processes of the conductive substrate layer, optical modulation layer, and display layer can be completed on different production lines, improving manufacturing efficiency and flexibility. Furthermore, the sequential stacking and connection of the optical modulation layer, conductive substrate layer, and display layer facilitates a thinner design for the display mechanism, allowing the thickness of the entire display mechanism and the sunroof using the display mechanism to be controlled within an extremely thin range. This reduces the impact of the display mechanism on the vehicle's interior space and enhances the user's driving experience.

[0069] Optionally, before sequentially stacking and connecting the prepared optical modulation layer, conductive substrate layer, and display layer to obtain the display mechanism, the manufacturing method of the display mechanism further includes:

[0070] Step 100: Select a substrate material and a conductive material, and prepare a conductive substrate layer based on the substrate material and the conductive material.

[0071] Specifically, the display mechanism includes a conductive substrate layer and a display layer. When the display mechanism is used in a vehicle sunroof, the display mechanism is connected to the sunroof body (which serves as the carrier of the display mechanism on the vehicle) through the conductive substrate layer. For example, the conductive substrate layer is connected to the sunroof body on the side of the sunroof body facing the inside of the vehicle, and the display layer is connected to the conductive substrate layer on the side of the substrate layer away from the sunroof body, so that the display mechanism can display corresponding content to the inside of the vehicle through the display layer, thereby meeting the user's image display needs for the car sunroof.

[0072] Regarding the manufacturing method of the display mechanism, firstly, in step 100, a substrate material and a conductive material are selected for preparing the conductive substrate layer, and the conductive substrate layer is prepared based on the substrate material and the conductive material. The conductive substrate layer serves to protect and support the display layer and other components of the display mechanism, thereby ensuring the stability and reliability of the display layer and the overall display mechanism. Furthermore, the conductive substrate layer is also provided with corresponding circuits for power supply and signal transmission for the display layer and related devices, to ensure the stable operation of the display mechanism, that is, to ensure that the display mechanism can emit light or display normally.

[0073] Optionally, combined Figure 2 , Figure 3 As shown, step 100 includes:

[0074] Step 110: Select a substrate material and pre-treat the substrate material to obtain a substrate layer that meets the preset performance requirements; wherein, the substrate material includes one of polyethylene terephthalate, cyclic olefin polymer and polyethersulfone, and the pre-treatment includes plasma treatment and primer coating treatment;

[0075] Step 120: Select a conductive material and print a conductive layer including a conductive circuit on the substrate using the conductive material and a preset printing technology; wherein, the conductive material includes one of metal nanowires, graphene, transparent conductive polymer and oxide semiconductor, and the preset printing technology includes at least one of printing technology and coating technology.

[0076] The conductive substrate layer includes a substrate layer and a conductive layer.

[0077] Specifically, in step 110, a suitable substrate material is selected and treated with appropriate pretreatment processes (such as plasma treatment, primer coating, etc.) to obtain a substrate layer that meets preset performance requirements. These preset performance requirements include mechanical strength requirements and chemical stability requirements. For example, a substrate layer that meets the preset performance requirements possesses good mechanical strength and chemical stability, enabling it to connect, protect, and support the display layer of the display mechanism, supporting the subsequent fabrication and operation of the display layer and conductive layer, and ensuring the stability and reliability of the display mechanism's operation. For the type of substrate material, one of PET (polyethylene terephthalate), COP (cyclic olefin polymer), and polyethersulfone (PES) can be used.

[0078] In step 120, by selecting a suitable conductive material, a conductive layer including conductive circuits is printed on the substrate layer using the conductive material and a pre-defined printing technology (such as printing and coating techniques). This layer is used for powering the display layer and corresponding devices, transmitting signals, etc. On one hand, it powers the display layer and corresponding devices (such as sensors) and enables signal transmission between them, ensuring the normal operation and effective control of the display mechanism. On the other hand, it ensures the entire display mechanism has a relatively thin thickness, reducing its footprint in the vehicle's interior space. For example, a material with good conductivity is used as the conductor material, and conductive lines are formed on the substrate layer through processes such as printing or deposition. These lines connect the display layer and the corresponding power supply, providing the necessary electrical signals to the display layer, allowing the display mechanism to emit light or display normally. In some embodiments, the conductive layer is also required to have high transparency to avoid obstructing the view from the sunroof. For the type of conductive material, one of the following can be used: metal nanowires (such as silver nanowires AgNWs), graphene, transparent conductive polymers (such as poly(3,4-ethylenedioxythiophene), abbreviated as PEDOT; or polyaniline (PANI)) and oxide semiconductors.

[0079] Optionally, pretreatment of the substrate material includes:

[0080] The substrate material is subjected to plasma treatment and primer coating treatment, wherein the primer used in the primer coating treatment includes acrylic or silane primers.

[0081] Specifically, to obtain a substrate layer that meets preset performance requirements, the substrate material needs to be pretreated. Specifically, plasma treatment is performed on the substrate material to improve its surface properties, enhance its adhesion and wettability to other materials, and improve its performance and durability in specific applications. Furthermore, plasma treatment can remove organic contaminants and impurities from the substrate material surface, making it cleaner and facilitating subsequent operations. A primer coating treatment is then applied to the substrate material, using processes such as dip coating, spraying, or brushing. This primer reacts with the polar groups on the substrate material surface through covalent bonds, forming a stable interface and improving the stability of the resulting substrate layer. Acrylic or silane primers can be used for this primer coating treatment.

[0082] Optionally, plasma treatment and primer coating of the substrate material include:

[0083] The substrate material is subjected to plasma treatment and primer coating treatment in sequence.

[0084] Specifically, by first subjecting the substrate material to plasma treatment and then applying a primer, the plasma treatment removes organic pollutants and impurities from the surface of the substrate material, making the surface cleaner and facilitating subsequent coating or bonding operations.

[0085] Optionally, printing a conductive layer including conductive circuits on the substrate layer using conductive materials and a pre-defined printing technique includes:

[0086] A conductive layer is printed on the substrate using conductive materials and pre-printed techniques, including micro-contact printing or screen printing.

[0087] Specifically, based on the selected conductive material, a pre-defined printing (or fabrication) technique (referred to as pre-defined printing technique) can be used to set the conductive layer on the substrate layer. This allows for a more detailed and precise conductive layer structure (or conductive circuit structure), and reduces the overall thickness of the conductive layer and display mechanism, resulting in a thinner display mechanism that reduces its footprint in the vehicle's interior space. Pre-defined printing techniques include micro-contact printing, screen printing, and other printing technologies.

[0088] Alternatively, a conductive layer may be printed on the substrate using a conductive material and a pre-defined coating technique, wherein the pre-defined coating technique includes spraying or roller coating.

[0089] Specifically, based on the selected conductive material, a pre-defined coating technique (hereinafter referred to as the pre-defined coating technique) can be used to set the conductive layer on the substrate layer to ensure the uniformity and conductivity of the conductive layer. The pre-defined coating technique includes spraying and roller coating techniques. Spraying technology uniformly sprays the conductive material onto the substrate surface under high pressure, enabling rapid coverage of large areas and is suitable for applications requiring intricate patterns or irregular surfaces. Roller coating technology uniformly coats the conductive material onto the substrate layer using a rotating roller, suitable for coating large areas and smooth surfaces, ensuring consistent coating thickness and surface smoothness.

[0090] Optionally, printing a conductive layer on the substrate using a conductive material and a pre-defined printing technique includes:

[0091] A conductive circuit pattern is formed on a substrate using photolithography. Stamp material is then added to cover the conductive circuit pattern and cured to obtain a stamp.

[0092] Conductive material is coated onto the raised areas of the stamp that correspond to the conductive circuit pattern. Then, the stamp material of the raised areas is pressed onto the base layer using a preset printing technique. After baking for a preset time, a conductive base layer is obtained.

[0093] Specifically, photolithography is used to form conductive circuit patterns on a substrate. This involves using photolithography to create the desired conductive circuit patterns on a substrate (such as a silicon wafer). For example, photoresist is coated onto the substrate, and after exposure, a development process is used to obtain the desired circuit patterns. These circuit patterns serve as templates for coating conductive materials. After forming the conductive circuit patterns on the substrate, a stamping material (such as PDMS (Polydimethylsiloxane, or silicone rubber)) is coated onto the formed conductive circuit patterns, completely covering them. Then, a curing process (such as UV curing or thermal curing) is used to cure the stamping material, resulting in a stamp corresponding to the conductive circuit patterns, with raised areas on the stamp surface matching the conductive circuit patterns. Next, conductive material is coated onto the raised areas corresponding to the conductive circuit patterns on the cured stamp. The conductive material can be in the form of conductive ink (such as conductive silver nanowire ink), conductive paste, etc., and is uniformly coated onto the raised areas using a coating process. Finally, using a preset printing technique (such as transfer printing or embossing printing), the raised areas of the stamp material coated with conductive material are imprinted onto the base layer, allowing the conductive material to transfer from the stamp to the base layer, forming a conductive layer consistent with the conductive circuit pattern. The imprinted base layer is then baked to ensure that the conductive material is fully cured on the base layer. The baking time and temperature are adjusted according to the characteristics of the conductive material to ensure the stability and conductivity of the conductive layer, thereby obtaining the desired conductive base layer.

[0094] Thus, by combining the advantages of photolithography and printing technologies, and utilizing the high-precision pattern generation capability of photolithography and the efficient transfer capability of printing, high-precision and high-efficiency manufacturing of the conductive layer is achieved. Photolithography forms the conductive circuit pattern, ensuring the accuracy of the circuit; the coating and imprinting of the stamp material efficiently transfers the conductive material onto the substrate layer, achieving precise forming of the conductive layer.

[0095] Optionally, fabricating the display layer on the conductive substrate layer includes:

[0096] A self-emissive display layer is fabricated on a conductive substrate, or a non-self-emissive display layer is fabricated on a conductive substrate.

[0097] Specifically, a self-emissive display layer can be fabricated on a conductive substrate, or a non-self-emissive display layer can be fabricated on a conductive substrate.

[0098] The fabrication of a self-emissive display layer on a conductive substrate includes:

[0099] Conductive adhesive is applied to multiple designated locations on a conductive substrate layer to fix multiple light-emitting structures to the multiple designated locations using conductive adhesive, wherein one light-emitting structure is set at each designated location.

[0100] The conductive substrate layer after the light-emitting structure is arranged is placed in an environment with preset temperature and preset pressure to cure the conductive adhesive, thus obtaining the display mechanism.

[0101] Specifically, for the fabrication of a self-emissive display layer on a conductive substrate, conductive adhesive is precisely applied to multiple predetermined designated locations on the conductive substrate. These locations are determined according to the design requirements and circuit pattern of the display layer, ensuring that each light-emitting structure (such as an OLED, LED, or other self-emissive element) can be correctly connected to the corresponding circuit of the conductive layer. Each light-emitting structure is placed on the designated location on the conductive substrate where conductive adhesive has been applied, ensuring good contact between each light-emitting structure and the conductive circuit. Subsequently, the conductive substrate with the light-emitting structures arranged is placed in an environment with preset temperature and pressure for curing treatment, ensuring that the conductive adhesive is completely cured, the light-emitting structure is firmly fixed, and a reliable electrical connection is formed with the conductive circuit. The curing process involves heating and pressurizing to harden the conductive adhesive, thereby firmly fixing the light-emitting structure to the conductive substrate and ensuring stable conductivity. The preset temperature and pressure are set appropriately based on the characteristics of the conductive adhesive and the light-emitting structure, ensuring that the adhesive does not damage the light-emitting structure or the conductive substrate during the curing process.

[0102] Optionally, after step 200, this method further includes:

[0103] The prepared touch layer is connected to the display mechanism to obtain the touch display mechanism.

[0104] Specifically, the touch layer is a layer that senses user touch operations and can employ capacitive or infrared touch technology. For example, after the display mechanism is installed on the sunroof body, the touch layer can be installed on the side of the display mechanism away from the sunroof body, i.e., the side closer to the passenger (or the user inside the vehicle), so that the user can control the operating parameters and displayed content of the display mechanism through touch operations. This further enriches the functionality of the smart display sunroof and enhances the user's interactive experience. The introduction of the touch layer enables the smart display sunroof to not only have a display function but also provide an intuitive interactive method. Users can control the sunroof's displayed content, adjust brightness, select functions, etc., through touch, improving operational convenience and user experience.

[0105] Optionally, when the display mechanism has an optical modulation layer, to ensure that the adjustment effect of the optical modulation layer is not affected, the material used for the base layer is preferably a transparent material. For example, in step 110, the base material selected for the base layer needs to consider properties such as transparency, UV resistance, and scratch resistance, so as to ensure the driving comfort of the vehicle occupants while ensuring the corresponding effect; for example, optical grade PET (polyethylene terephthalate), COP (cyclic olefin polymer), or polyethersulfone (PES) can be selected as transparent base materials.

[0106] For ease of understanding, the following example uses polyethersulfone (PES) as the substrate material. PES is a polymer material produced by the polycondensation reaction of bisphenol A and dichlorodiphenyl sulfone. It is highly favored in high-end applications due to its excellent mechanical properties, heat resistance, transparency, and chemical resistance. PES materials remain stable under high temperature and strong light conditions, making them an ideal choice for automotive sunroofs. However, because the surface characteristics of PES films are not suitable for subsequent conductive layers, appropriate pretreatment of the PES film is required. This pretreatment may include plasma treatment, and an acrylic or silane primer may be applied depending on the specific application.

[0107] For example, the main purpose of plasma treatment of PES films is to improve their surface properties, enhance their adhesion and wettability with other materials, and thus improve their performance and durability in specific applications. Plasma treatment can remove organic contaminants and impurities from the surface of PES films, making the surface cleaner and facilitating subsequent coating or bonding operations. During plasma treatment, the molecular formula of the PES film does not undergo substantial changes; only the surface of the material is modified, rather than its chemical composition or molecular structure altered. Plasma treatment introduces new functional groups—polar groups (hydroxyl groups -OH)—on the surface of the PES film, giving it stronger hydrophilicity. These hydroxyl functional groups can enhance the adhesion of the PES film to other materials through hydrogen bonds or covalent bonds. In some embodiments, the recommended plasma treatment parameters are as follows: gas flow rate of 0.5 L / min, power set at 400-600 W, treatment atmosphere (argon and oxygen mixture), and treatment time of 2-5 minutes. For primer coating, a silane primer can be used for PES films, with a dilution ratio of 1:1. The primer can react with the polar groups on the PES surface through covalent bonds to form a stable interface. The coating process can be dip coating, spray coating, or brush coating. If spray coating is used, the drying time after coating is 2-4 hours, and it should be carried out in an environment of 60-80℃ to ensure the coating effect.

[0108] Optionally, for step 120, the conductive layer material can be selected first, such as a metal nanowire network (e.g., silver nanowires, AgNWs) with high transparency and excellent conductivity. The silver nanowire network is prepared on a substrate layer (e.g., a PES substrate layer) using high-precision printing techniques (e.g., micro-contact printing, screen printing) to form a highly transparent and uniform conductive layer. Alternatively, it can be prepared by spraying or roll coating. In some embodiments, in addition to metal nanowires, graphene, transparent conductive polymers (e.g., poly(3,4-ethylenedioxythiophene), abbreviated as PEDOT; or polyaniline (PANI)) or oxide semiconductors can also be selected as the conductive layer material.

[0109] For ease of understanding, the following example illustrates the fabrication of a conductive layer using microcontact printing technology. Microcontact printing technology enables high-resolution patterning at the micrometer level, facilitating the creation of more detailed and precise conductive layer structures. The fabrication process using microcontact printing involves several steps: First, a stamp is prepared by using photolithography to create a pattern on a silicon wafer. Then, PDMS (Polydimethylsiloxane, or silicone rubber) is poured in and cured to form the stamp. Next, ink is loaded by coating conductive silver nanowire ink onto the raised pattern portion of the stamp. Microcontact printing then occurs, where an automated machine smoothly presses the stamp onto the substrate, transferring the silver nanowire ink to form the conductive pattern. The printing pressure is crucial in microcontact printing, typically ranging from 7 to 9 kPa. Finally, baking, such as at 150°C for approximately 30 minutes, promotes the curing and conductivity of the silver nanowires.

[0110] Optionally, for fabricating a display layer on a conductive substrate, the following explanation uses the fabrication of a self-emissive display layer using micro-LEDs as an example. Micro-LEDs are embedded in the substrate (the micro-LEDs are embedded into the conductive substrate composed of the substrate layer and the conductive layer, forming a thin and uniform display layer; each LED can be individually controlled, thereby achieving the display of complex patterns and dynamic visual effects, enabling the display to range from simple monochrome patterns to complex dynamic images or videos). Specifically, micro-LEDs are arranged using a dispensing method. An appropriate amount of conductive adhesive (such as a silver paste-based conductive adhesive with high conductivity and reliability) is applied to the conductive circuit (or conductive layer), and then the micro-LEDs are attached to the designated positions. A precision dispensing machine can be used to apply an appropriate amount of conductive adhesive to the designated positions on the conductive circuit. When using a dispensing machine to apply conductive adhesive, the machine's parameters need to be set, including adhesive flow rate, pressure, and dispensing head movement speed. Adhesive flow rate refers to the speed at which the adhesive flows from the nozzle or injection needle of the dispensing machine. The flow rate should be selected based on the size and spacing of the micro-LEDs and conductive circuits to ensure that the adhesive is evenly applied to the designated locations on the conductive circuits. For micro-LED dispensing, a lower flow rate is typically required to precisely control the amount of adhesive dispensed, such as 0.3 ml / s. Pressure refers to the force applied to the adhesive by the dispensing machine, affecting the speed and uniformity of the adhesive flow. The pressure should be selected based on the model of the dispensing machine and the viscosity of the adhesive. For micro-LED dispensing, moderate pressure is usually required to ensure a stable flow of adhesive and the formation of a uniform coating at the dispensing location. Excessive pressure may cause the adhesive to flow too quickly or be sprayed too far, resulting in poor dispensing effects; for example, a pressure of 200 kPa may be used. In addition, a micro-robot can be used to precisely place the micro-LEDs at the dispensing positions, ensuring that each micro-LED is accurately placed and fixed to ensure uniform light distribution and high-resolution display effect. During this process, by adjusting the magnification and focal length of the microscope built into the robot, it is ensured that the contact between the micro-LEDs and the conductive adhesive can be clearly observed, ensuring that the positive and negative terminals of the LEDs are connected to the corresponding positions of the conductive circuit.

[0111] After the micro-LEDs are arranged and dispensed on the substrate, the substrate (such as a PES substrate) with the micro-LEDs arranged is placed on a heating plate. The temperature and pressure of the heating plate are set, such as 100℃ and 0.4MPa, to ensure that the conductive adhesive can be cured quickly at the appropriate temperature, so that the conductive adhesive is firmly connected to the micro-LEDs and conductive circuits without damaging the substrate.

[0112] Then, each pixel (corresponding to each microLED) needs to undergo electrical and optical testing to ensure the quality of the connection. This can be done by observing with a microscope and using automated inspection equipment to check the placement and bonding quality of each LED.

[0113] Optionally, after step 100 and before step 200, this method further includes:

[0114] Based on the conductive substrate, corresponding sensors and processors are installed on the conductive substrate.

[0115] A processor and sensors are integrated onto the conductive substrate layer of the display mechanism. Specifically, the processor (used for communication with other devices and controlling the display of content on the smart sunroof) and sensors (such as sensors for collecting and acquiring light information inside and outside the vehicle) are placed on the substrate layer, and power supply and electrical connection with other devices are achieved through the conductive layer. In this way, the processor and sensors control the display mechanism's display and response to changes in the external environment (such as light information), ensuring that the corresponding parameters of the display mechanism can be precisely adjusted to improve the display effect.

[0116] Optionally, after the display mechanism and corresponding components are manufactured, electrical and optical tests are performed on the corresponding components and the entire display mechanism to ensure that they can work normally and achieve the expected display effect.

[0117] Optionally, the power supply for the display mechanism of the intelligent display sunroof can be provided by the vehicle's corresponding power source.

[0118] Optionally, after obtaining the display mechanism, the method further includes:

[0119] The obtained display mechanism is encapsulated and reinforced to obtain a display mechanism for assembly onto the sunroof body.

[0120] Specifically, to ensure the overall structural strength and stability of the display mechanism assembled onto the sunroof body, the resulting display mechanism needs to be encapsulated and reinforced to ensure its durability and applicability, while maintaining sufficient strength and transparency. For example, the intelligent display sunroof consists of a multi-layered structure, such as laminated glass, achieving the following structure: glass + base layer + conductive layer + display layer + protective layer + glass, thus protecting the display mechanism. In some embodiments, since the LEDs and circuits used in the corresponding display layer cannot achieve 100% transparency, a color mixing mode can be used to perform corresponding color and structural de-polarization on the inside of the glass, minimizing the passenger's perception of the internal components and improving the user experience.

[0121] Optionally, the display mechanism (such as an LED panel) can be directly fabricated on the sunroof body, or the display mechanism can be fabricated first and then integrated with the sunroof body through processes such as adhesive bonding or hot pressing. In some embodiments, the display mechanism and the sunroof body are detachably connected, such as through fasteners, clips, or magnetic attraction, which improves the convenience of installing and removing the display mechanism from the sunroof body and enables the display mechanism to have multiple application scenarios, allowing the display mechanism to be used independently outside the vehicle interior environment.

[0122] Another embodiment of the present invention provides a method for manufacturing an intelligent display skylight, comprising:

[0123] The display mechanism prepared using the above manufacturing method is installed onto the skylight body to obtain an intelligent display skylight.

[0124] Specifically, the prepared display mechanism is installed on the corresponding position of the sunroof body to complete the manufacturing of the intelligent display sunroof, thereby obtaining an intelligent display sunroof that can display the corresponding content required by the user to meet the user's functional needs for image display and other functions of the car sunroof.

[0125] Another embodiment of the present invention provides a control method for an intelligent display skylight, based on the intelligent display skylight described above; the control method for the intelligent display skylight includes:

[0126] Based on the acquired content to be displayed by the display mechanism and the light information inside and outside the intelligent display skylight, determine the optimal operating parameters for the display mechanism to display the content under the light information.

[0127] The control display mechanism displays the content to be displayed based on the optimal operating parameters.

[0128] Specifically, by installing a smart display sunroof in a vehicle, it can display relevant content (such as text, images, animations, videos, etc.) required by the user, thus satisfying the user's functional needs for image display and other features of the car (or vehicle) sunroof. Specifically, the smart display sunroof includes a sunroof body and a display mechanism mounted on the sunroof body. The smart display sunroof displays relevant content through the display mechanism. For example, the display mechanism is located on the inner side of the sunroof body (i.e., the side of the sunroof body facing the interior of the vehicle) to prevent potential damage from long-term exposure to the external environment.

[0129] For the control of the intelligent display sunroof, considering the different content displayed by the display mechanism and the influence of light inside and outside the intelligent display sunroof (or inside and outside the vehicle) on the content displayed by the display mechanism (which is reflected in the influence of the corresponding light on the user's viewing experience of the content displayed by the display mechanism), in order to ensure that the user obtains the best viewing experience of the content displayed by the display mechanism, it is necessary to combine the content to be displayed by the display mechanism (the content to be displayed) and the light information inside and outside the intelligent display sunroof (including light intensity, light color temperature, light direction, etc.) to adjust the corresponding operating parameters of the display mechanism (such as display brightness, color contrast, and transparency, etc.). Specifically, firstly, the content to be displayed by the display mechanism and the current light information inside and outside the intelligent display sunroof are obtained. Based on the obtained content to be displayed and light information, the operating parameters suitable for the display mechanism to display the content to be displayed under the current light information (or to obtain the best viewing experience for the user) are determined (denoted as the optimal operating parameters). When the content to be displayed needs to be displayed on the display mechanism, the display mechanism is controlled to use the optimal operating parameters as the current operating parameters to display the content to be displayed. The content to be displayed can come from the user. For example, the user can transmit the content to be displayed to the intelligent display sunroof through a vehicle-mounted system or mobile terminal that is connected to the intelligent display sunroof, so as to meet the user's personalized and customized needs.

[0130] Thus, this embodiment's method, based on vehicles equipped with intelligent sunroofs, can display the content desired by the user on the intelligent sunroof, satisfying the user's personalized and customized needs for image display on the sunroof and enriching the functionality of the vehicle sunroof. Specifically, based on the acquired content to be displayed by the display mechanism and the light information inside and outside the intelligent sunroof, the optimal operating parameters for the display mechanism to display the content under the light information are determined. The display mechanism is then controlled to display the content based on the optimal operating parameters. This ensures that the display mechanism can achieve the best display effect under different lighting conditions, that is, ensures that the user can obtain the best viewing experience under different lighting conditions. This achieves optimized display of the intelligent sunroof under different lighting conditions, improving the user experience while meeting personalized user needs.

[0131] Optionally, the operating parameters include at least one of the display layer's display brightness, color contrast, transparency, and transmittance.

[0132] Specifically, the operating parameters of a display mechanism include the display layer's brightness, color contrast, transparency, and transmittance. Display brightness refers to the intensity of light emitted by the display layer, i.e., the intensity or brightness level of the light produced by the display layer. By adjusting the display brightness, the visibility and clarity of the displayed content can be controlled, ensuring that the content displayed by the mechanism is clearly visible under different lighting conditions, thus improving user experience and viewing comfort. Color contrast refers to the degree of contrast between different colors in the display layer, i.e., the degree of difference between the colors displayed by the display layer. Optimizing color contrast can enhance the vibrancy and realism of the displayed content, making images, text, or videos more vivid and lifelike. Transparency indicates the degree to which the display layer allows light to pass through, meaning whether the scenery behind the display layer is clearly visible. Higher transparency means more light can pass through, and the scenery behind the display layer is more clearly visible (e.g., scenery outside the car is seen by the user inside the car through the display mechanism). Lower transparency means less light passes through, and the scenery behind the display layer becomes unclear or even invisible. Adjusting transparency affects the light transmission between the inside and outside of the sunroof, thereby adjusting the light illumination and light transmission inside the car, providing a more comfortable interior environment and visual experience. Light transmittance indicates the ability of the display layer to transmit light, meaning the degree to which light passes through the display layer. High light transmittance means more light can pass through the display layer, while low light transmittance means the display layer obstructs light more. By adjusting light transmittance, the degree of light transmission can be controlled, achieving the purpose of adjusting the interior light and visibility. Thus, by adjusting these operating parameters, the intelligent display sunroof can provide the best display effect under different lighting conditions, achieving the corresponding optimal operating parameters, thereby improving the user experience and driving comfort.

[0133] Optionally, the display layer includes a self-emissive display layer, and the operating parameters include the display brightness and color contrast of the self-emissive display layer; or, the display layer includes a non-self-emissive display layer and at least one of a backlight layer and a front light layer, and the operating parameters include the display brightness and color contrast corresponding to at least one of the non-self-emissive display layer and the backlight layer and the front light layer.

[0134] Specifically, the display layer can be a self-emissive display layer for displaying content. A self-emissive display layer (such as a display layer / panel using OLED or Micro LED that is self-emissive and requires no backlight) can emit its own light, requiring no external light source. Each pixel can independently control its luminous intensity and color, achieving high contrast and vibrant color display. Thus, using a self-emissive display layer eliminates the need for an additional backlight or front light layer, allowing for thinner, lighter, and more energy-efficient designs. The display layer can also be a non-self-emissive display layer with a compatible light source (such as a backlight layer or front light layer). Non-self-emissive display layers (such as display layers using LCD (Liquid Crystal Display) or electronic ink technology / electronic ink screens) do not emit light themselves and require an external light source (backlight layer or front light layer) to enhance the viewing experience. In this design, if the side of the non-self-emissive display layer facing the user is defined as the front side, and the side away from the user as the rear side, then the backlight layer and the front light layer are configured as follows: the backlight layer is positioned behind the non-self-emissive display layer, illuminating it to make the content visible; the front light layer is positioned in front of the non-self-emissive display layer, providing additional illumination to improve visibility. For example, for a non-self-emissive display layer using an LCD, it combines with the backlight layer to achieve clear visibility of the displayed content; for a non-self-emissive display layer using e-ink technology / e-ink screens, it can be used under natural light, or it can combine with the front light layer to achieve clear visibility of the displayed content. For example, in environments with low natural light intensity, the front light layer illuminates to ensure clear visibility of the content displayed on the non-self-emissive display layer using e-ink technology / e-ink screens. In some embodiments, the front light layer of the display layer can be used to provide illumination for the vehicle interior, or the vehicle's interior lighting fixtures can serve as the front light layer of the display layer. The display layer can also employ both self-emissive and non-self-emissive display layers (which can be used in conjunction with at least one of the backlight layer and the front light layer). For example, based on the corresponding usage requirements, the display layer can be partitioned, with some areas using self-emissive display layers and others using non-self-emissive display layers, thus achieving a combination of self-emissive and non-self-emissive display layers. This further enriches the functionality of the smart display skylight and provides users with more options for personalized customization of image display.

[0135] Regarding operating parameters, self-emissive display layers (such as OLED and Micro LED) can emit light themselves, and each pixel can independently control its luminous intensity and color. Therefore, the display brightness and color contrast of the display layer are the same as those of a self-emissive display layer. Non-emissive display layers (such as LCD or e-ink screens) require an external light source (backlight layer or front light layer) to illuminate the displayed content. Adjusting the display brightness and color contrast of the display layer requires adjusting the corresponding parameters of at least one of the non-emissive display layer and the external light source. For example, for LCD screens, the brightness of the backlight layer can adjust the overall brightness of the display, thus affecting the display brightness of the display layer. The color contrast of an LCD screen can be adjusted by adjusting the transparency of the liquid crystal layer and the brightness of the backlight layer. The transparency of the liquid crystal layer affects the degree to which pixels block light, while the brightness of the backlight layer affects the overall light intensity. Adjusting both in combination can adjust the color contrast. For e-ink screens, illumination is usually provided by a front light. Therefore, adjusting the display brightness can also be achieved by adjusting the brightness of the front light layer. Adjusting the color contrast generally requires adjusting the display colors of the e-ink screen.

[0136] Optionally, the conductive substrate layer is made of a transparent material (or the conductive substrate layer is a transparent component); the operating parameters also include at least one of the transparency and transmittance of the optical modulation layer.

[0137] Specifically, an optical modulation layer is disposed between the conductive substrate layer and the sunroof body. Its transparency and / or transmittance are adjustable to regulate the intensity of light entering the vehicle through the sunroof, ensuring optimal display of content on the smart display sunroof and providing the best viewing experience for the user. Alternatively, when the smart display sunroof is not displaying content, adjusting the transparency and / or transmittance of the optical modulation layer can achieve shading (corresponding to lower transparency and / or transmittance, acting as a sunshade or privacy protector) or enhance the sunroof viewing experience (corresponding to higher transparency and / or transmittance). Accordingly, the conductive substrate layer (including the conductive layer and the substrate layer) uses a (high) transparent material to ensure effective light transmission, allowing the adjustment of the optical modulation layer's transparency and / or transmittance to directly affect the display layer or the vehicle interior. In some embodiments, the display mechanism also requires a structure with high transparency (when not displaying content) to ensure that the sunroof viewing experience can be enhanced by increasing the transparency and / or transmittance of the optical modulation layer when no content is displayed.

[0138] For example, the optical modulation layer may employ a liquid crystal layer (such as an electronically controlled liquid crystal layer or a polymer dispersed liquid crystal (PDLC) film) or an electrochromic material to change its light transmittance according to changes in electrical signals, thereby controlling the light transmittance of the sunroof and maintaining a comfortable lighting environment or an optimal display environment in different in-vehicle and out-of-vehicle lighting conditions. For instance, when the intelligent display sunroof needs to display corresponding content, the optical modulation layer can be adjusted to a black substrate to minimize the impact of external light on the content display. In some embodiments, the optical modulation layer may employ a film structure to facilitate smooth adhesion to the sunroof body and reduce its footprint in the vehicle interior.

[0139] Optionally, based on the acquired content to be displayed for the display mechanism and the light information inside and outside the intelligent display skylight, the optimal operating parameters for the display mechanism to display the content to be displayed under the light information are determined, including:

[0140] Based on the acquired control commands for the intelligent display sunroof, determine the content to be displayed corresponding to the control commands.

[0141] The intelligent sunroof can interact with users or corresponding devices to display content according to commands or input, meeting users' personalized needs. Specifically, based on the acquired control commands for the intelligent sunroof, these commands can be input by the user through the sunroof's touch layer, or through the vehicle's infotainment system or corresponding mobile terminal device connected to the sunroof. For example, the user can issue a voice control command through the vehicle's voice module, which will then be parsed and sent to the intelligent sunroof for execution; alternatively, the intelligent sunroof can recognize content from external devices (such as USB drives) through the corresponding interface of the vehicle's infotainment system and display it according to the corresponding control commands; or, the user can use a mobile terminal (such as a mobile phone) connected to the intelligent sunroof to determine the content to be displayed by the intelligent sunroof and the control commands to display that content based on the corresponding application on the mobile terminal.

[0142] To facilitate understanding, the following example uses displayed content as an image to illustrate the interaction method and editable content of the smart sunroof display. The pattern to be displayed by the smart sunroof is determined through mobile phone software or the car's built-in software, and then converted into a format recognizable by the display mechanism. Specifically, dedicated software needs to be developed that runs on the in-vehicle computing platform (car infotainment system) or on a mobile phone connected to the smart sunroof. This software needs to have image file recognition and decoding capabilities, and be able to handle common image formats such as JPEG and PNG. Additionally, an image processing algorithm for the smart sunroof needs to be developed to convert the read (or received) pattern file into a format recognizable and displayable by the LED display screen. This may include adjusting image resolution, contrast, brightness, and color format conversion. For large images, segmentation processing is also required to ensure smooth display in different areas on the display mechanism. In interactive processes such as content transmission and display, the image data processed by the corresponding software is transmitted to the intelligent display sunroof. Upon receiving the data, the controller (or processor) of the intelligent display sunroof identifies and decodes it, then maps the resulting image data onto each pixel of the display layer of the display mechanism, controlling the brightness and color of each pixel to present the final image. The design of the corresponding software and algorithms needs to consider real-time performance, data transmission stability, and optimized display effects, ensuring high efficiency and low latency in data transmission and processing to provide a smooth and clear display. Furthermore, the software interface should be designed to be user-friendly, allowing drivers or passengers to easily select and preview images.

[0143] Based on the content to be displayed and the acquired light information, determine the optimal operating parameters for the display mechanism to display the content under the given light conditions.

[0144] Specifically, based on the acquired content to be displayed and light information, the operating parameters (denoted as optimal operating parameters) suitable for the display mechanism to best display the content to be displayed (or for the user to obtain the best viewing experience) under the current light information are determined; when the content to be displayed needs to be displayed on the display mechanism, the display mechanism is controlled to use the optimal operating parameters as the current operating parameters to display the content to be displayed.

[0145] Optionally, based on the functionality of the intelligent display sunroof, it can be used in natural light illumination, entertainment display or business presentation, etc., to provide passengers with a variety of visual experiences.

[0146] Optionally, the shape and size of the sunroof may vary for different car models and sizes. To enable intelligent display sunroofs on cars of different models and sizes, intelligent display sunroofs can be customized according to specific parameters such as the shape and size of the sunroof.

[0147] Optionally, for the control of the smart display sunroof, artificial intelligence (AI) algorithms can also be integrated. Based on the hardware of the smart display sunroof and the vehicle's infotainment system, the smart sunroof can automatically adjust the displayed content according to user habits and preferences. For example, AI can predict and adjust the most suitable display mode of the smart display sunroof by analyzing environmental data and user interaction.

[0148] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
