[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are 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, which is applied to a vehicle, and the display mechanism includes:

[0033] an optical modulation layer, at least one of transparency and light transmittance of which is suitable for adjustment;

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

[0035] A conductive substrate layer for supplying power to the display layer;

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

[0037] In this embodiment, the display mechanism is used to be installed (or set) on the sunroof body of the vehicle, so as to display corresponding content (such as text, images, animations, videos, etc.) through the display mechanism at the position of the sunroof body of the vehicle, meeting the user's needs for personalization and customization of the image display of the car sunroof. Among them, the sunroof is divided into two types: an openable sunroof and a closed sunroof (i.e., a skylight), and the sunroof body is a light-transmitting component of the sunroof (such as a light-transmitting component made of glass or other materials); the sunroof body is used as a carrier of the display mechanism on the vehicle for the installation or setting of the display mechanism.

[0038] Specifically, the display mechanism includes an optical modulation layer, a conductive substrate layer and a display layer, and the display layer is used to display corresponding content to meet the user's image display needs for the car sunroof. The conductive substrate layer is used to supply power to the display layer, and to protect and support the display layer of the display mechanism, so as to ensure the stability and reliability of the display layer and the display mechanism as a whole. Among them, the conductive substrate layer is provided with corresponding circuits for powering the display layer and corresponding devices, signal transmission, etc., to ensure that the display mechanism can operate stably, that is, to ensure that the display mechanism can emit light or display normally. At least one of the transparency and transmittance of the optical modulation layer itself is suitable for adjustment, so as to adjust the light passing through the optical modulation layer inside and outside the vehicle by adjusting the transparency and / or transmittance of the optical modulation layer, to adjust the overall display effect of the display mechanism, etc., to optimize the overall display effect of the display mechanism and enhance the user experience.

[0039] For the display mechanism, its optical modulation layer, conductive substrate layer and display layer are stacked in sequence to ensure that there is a large contact area between the optical modulation layer and the conductive substrate layer, and between the conductive substrate layer and the display layer, so as to facilitate the stable bonding between the optical modulation layer, the conductive substrate layer and the display layer, thereby improving the stability of the connection between the optical modulation layer, the conductive substrate layer and the display layer after connection, and ensuring the stability and reliability of the operation of the display mechanism. For the connection between the display mechanism and the sunroof body of the vehicle, the display mechanism is preferably arranged on the inner side of the sunroof body (i.e., the side of the sunroof body facing the interior of the vehicle) to avoid the possibility of damage to the display mechanism due to long-term exposure to the environment outside the vehicle. Accordingly, the side of the optical modulation layer away from the conductive substrate layer is used to connect with the side of the sunroof body of the vehicle facing the interior of the vehicle, that is, in the direction of the sunroof body pointing to the interior of the vehicle (or the vehicle cabin), the sunroof body, the optical modulation layer, the conductive substrate layer and the display layer are connected in sequence. Among them, the transparency and / or transmittance of the optical modulation layer can be adjusted. By adjusting at least one of the transparency and transmittance of the optical modulation layer, the intensity and direction of the light passing through the optical modulation layer can be changed to adjust the light entering the car through the sunroof body outside the car, thereby adjusting the display effect of the display mechanism, etc., to ensure the best display effect of the display mechanism for the corresponding content and the best viewing experience of the user; or, when the display mechanism is not required to display the corresponding content, the transparency and / or transmittance of the optical modulation layer can be adjusted to achieve shading (corresponding to lower transparency and / or transmittance, which plays a role of shading, protecting privacy, etc. similar to sunshades) or improve the viewing experience of the sunroof (corresponding to higher transparency and / or transmittance). Correspondingly, the conductive substrate layer adopts (high) transparent materials to ensure that light can pass through effectively, and to ensure the viewing experience of the user in the car 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 higher transparency (when no content is displayed) to ensure that the viewing experience of the sunroof can be improved 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 provided on the sunroof body of the vehicle to display the corresponding content required by the user, so as to meet the user's functional requirements for the image display of the car (or vehicle) sunroof, etc. Specifically, the display mechanism displays the corresponding content by providing a display layer to meet the user's image display requirements for the car sunroof, etc.; by providing a conductive substrate layer, the display layer of the display mechanism is powered, protected and supported to ensure that the display mechanism can operate stably, and the stability and reliability of the display layer and the display mechanism as a whole are ensured; by providing an optical modulation layer suitable for adjusting at least one of its own transparency and transmittance, the light passing through the optical modulation layer inside and outside the vehicle is adjusted by adjusting the transparency and / or transmittance of the optical modulation layer, so as to adjust the overall display effect of the display mechanism, etc., so as to optimize the overall display effect of the display mechanism and enhance the user experience. Moreover, the optical modulation layer, the conductive substrate layer and the display layer are stacked in sequence. On the one hand, the stability of the connection between the optical modulation layer, the conductive substrate layer and the display layer can be improved to ensure the stable operation of the display mechanism. On the other hand, the stacking arrangement facilitates the thin design of the display mechanism, so that the thickness of the entire display mechanism and the sunroof using the display mechanism is controlled within an extremely thin range, so as to reduce the impact of the display mechanism on the interior space of the vehicle and improve the user's driving experience. In addition, the display mechanism is arranged on the side of the sunroof body facing the interior of the vehicle to avoid the possibility of damage to the display mechanism due to long-term exposure to the environment outside the vehicle, thereby extending the service life of the display mechanism.

[0041] Optionally, the optical modulation layer can be used to adjust optical parameters such as transparency and transmittance, thereby adjusting the 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 arranged 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 facing away from the conductive layer is connected to the side of the sunroof body facing the interior of the vehicle through an optical modulation layer, the substrate layer is a transparent part, 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 arranged on the substrate layer. The substrate layer is used to connect, protect, support, etc. the display layer of the display mechanism, and to support the preparation and operation of the subsequent display layer and conductive layer, etc., to ensure the stability and reliability of the operation of the display mechanism. The conductive layer is a structure used for power supply and signal transmission of the display layer and corresponding devices, which is arranged on the substrate layer using conductive materials. The substrate layer, the conductive layer and the display layer are connected in sequence (stacked) to ensure the stable connection between the conductive substrate layer and the display layer, the stable operation of the display layer, etc.; and the side of the substrate layer facing away from the conductive layer is connected to the side of the sunroof body facing the interior of the vehicle through the optical modulation layer, that is, in the direction where the sunroof body points to the interior of the vehicle (or the vehicle cabin), the sunroof body, the optical modulation layer, the substrate layer, the conductive layer and the display layer are connected in sequence.

[0044] Moreover, the base layer is a transparent member, that is, the base layer is made of transparent material, such as highly transparent material, 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 act on 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 adopts 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 the transparency and / or transmittance of the optical modulation layer itself; exemplarily, the optical modulation layer may adopt a liquid crystal layer (such as a liquid crystal layer combined with an electronic control or a polymer dispersed liquid crystal (PDLC, polymerdispersed liquid crysta) film) or an electrochromic material to change its transmittance according to the change of the electrical signal, and control the light transmittance of the sunroof, so as to maintain a comfortable light environment or an optimal display environment in different light environments inside and outside the car; or the optical modulation layer adopts a photochromic material to realize that the sunroof automatically adjusts the color and transmittance under different lighting conditions, so as to maintain a comfortable light environment or an optimal display environment in different light environments inside and outside the car. For example, when the sunroof needs to display the corresponding content intelligently, the optical modulation layer can be adjusted to a black substrate to minimize the influence of the light outside the sunroof on the content display. In some embodiments, the optical modulation layer can adopt a diaphragm structure so as to smoothly fit on the sunroof body and reduce the space occupied in the car.

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

[0046] In this embodiment, the display layer may be a self-luminous display layer for displaying the corresponding content, wherein the self-luminous display layer (such as a display layer / display panel that is self-luminous and does not require a backlight source, such as OLED or Micro LED) can emit light by itself without the need for an external light source, and each pixel thereof can independently control its luminous intensity and color to achieve high contrast and bright color display. In this way, a self-luminous display layer is used without the need for an additional backlight or frontlight layer, so that the self-luminous display layer can be thinner and lighter, and more energy-efficient. The display layer may also be a non-self-luminous display layer, such as a display layer using LCD (Liquid Crystal Display) or electronic ink technology / electronic ink screen, which does not emit light itself. In some embodiments, the non-self-luminous display layer needs to be combined with an external light source (backlight layer or frontlight layer) to enhance the viewing experience.

[0047] Optionally, the self-luminous display layer includes a plurality of light-emitting structures which are arranged at preset designated positions of the conductive layer and are electrically connected to the conductive layer; the light-emitting brightness and light-emitting color of each light-emitting structure of the self-luminous 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 base layer, a corresponding light-emitting structure is disposed at a corresponding position of the conductive layer (recorded as a preset designated position), and the conductive layer is electrically connected to the light-emitting structure at the position (preset designated position) to power the light-emitting structure through the conductive layer and realize independent control of the light-emitting brightness and light-emitting color of each light-emitting structure. By providing multiple light-emitting structures, and the light-emitting brightness and light-emitting color of each light-emitting structure of the self-luminous display layer are suitable for independent control, each light-emitting structure can be used as a pixel point of the display layer to display the corresponding content, so that the display of a variety of different contents can be realized through different combinations of whether the corresponding light-emitting structure emits light, the light-emitting brightness and the light-emitting color, etc., to meet the user's image display requirements for the car sunroof, etc.

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

[0050] In this embodiment, when the display layer adopts a non-self-luminous display layer, a light source adapted to the non-self-luminous display layer is provided to enhance the user's viewing experience of the display layer. That is, the non-self-luminous display layer (such as a display layer using LCD (Liquid Crystal Display) or electronic ink technology / electronic ink screen, etc.) does not emit light by itself, and needs to be combined with an external light source (backlight layer or front light layer) to enhance the viewing experience. Among them, if the side of the non-self-luminous display layer facing the user is set as the front side, and the side away from the user is set as the back side, for the backlight layer and the front light layer, there are: the backlight layer is set on the back side of the non-self-luminous display layer, and the non-self-luminous display layer is illuminated by light to make the content visible; the front light layer is set on the front side of the non-self-luminous display layer to provide additional lighting to improve visibility. For example, for a non-self-luminous display layer using LCD, it is combined with the backlight layer to emit light to achieve clear visibility of the corresponding display content, etc.; for a non-self-luminous display layer using electronic ink technology / electronic ink screen, it can be used under natural light, or it can be combined with the light emission of the frontlight layer to achieve clear visibility of the corresponding display content, etc. For example, in an environment with low natural light intensity, the frontlight layer emits light to achieve clear visibility of the content displayed by the non-self-luminous display layer using electronic ink technology / electronic ink screen. In some embodiments, the frontlight layer of the display layer can be used to provide lighting for the interior of the vehicle, or the lighting fixtures in the vehicle can be used as the frontlight layer of the display layer.

[0051] Optionally, the display mechanism further includes a touch layer arranged on a side of the display layer away from the conductive substrate layer.

[0052] In this embodiment, the touch layer is a layer that senses the user's touch operation, and a capacitive or infrared touch technology can be used. For example, when the display mechanism is used to display the corresponding content in 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 interior space of the vehicle (i.e., the side close to the passengers / users in the vehicle), so that the user can control the operating parameters, display content, etc. of the display mechanism by touching the touch layer. In this way, the functionality of the vehicle sunroof using the display mechanism is further enriched, and the user interaction experience is enhanced, that is, the introduction of the touch layer enables the vehicle sunroof to not only have a display function, but also provide an intuitive interaction method. The user can control the content displayed on the sunroof, adjust the brightness, select functions, etc. by touching, thereby improving the convenience of operation and user experience.

[0053] Optionally, the display mechanism further includes a controller for communicating with the display layer, and an optical sensor for communicating with the controller or the vehicle computer; the controller is used for communicating with at least one of the vehicle computer and the mobile terminal.

[0054] In this embodiment, the display mechanism also includes a controller for communication connection with the display layer, and the controller is used to communicate with at least one of the vehicle computer and the mobile terminal. Specifically, the controller (or processor) is connected to the display layer (such as through the corresponding circuit of the conductive layer), and the display mechanism drives (or controls) the display layer to display the corresponding content through the controller. And the controller is connected to at least one of the vehicle computer and the mobile terminal to realize the communication connection between the display mechanism and at least one of the vehicle computer and the mobile terminal (such as a mobile phone and other devices), so that the content to be displayed that needs to be displayed by the display mechanism is transmitted to the display mechanism for display through the vehicle computer or the mobile terminal. Among them, the controller (or processor) can adopt a microprocessor so that it can be integrated on the display mechanism to reduce the overall occupied space of the display mechanism.

[0055] The display mechanism also includes a light sensor that is communicatively connected to the controller or the vehicle's head unit, and the head unit is communicatively connected to the controller. Specifically, the display mechanism also includes a light sensor (such as a photosensitive sensor, an optical fiber sensor, etc.) that is communicatively connected to the controller or the head unit (which is communicatively connected to the controller), so that the controller or the head unit can adjust the corresponding operating parameters of the display mechanism according to the light information inside and outside the vehicle collected by the light sensor, so as to obtain a better display effect or viewing effect, etc., wherein the light sensor is used to collect the corresponding light information outside and / or inside the vehicle (such as light intensity, light color temperature, light direction, etc.). In some embodiments, the light sensor can be integrated on the display mechanism (such as integrated on the conductive substrate layer of the display mechanism) or be independent of the overall structural setting of the display mechanism (that is, not integrated on the display mechanism, but communicatively connected to the controller of the display mechanism).

[0056] Optionally, the controller and the light sensor may be integrated on the conductive substrate layer of the display mechanism. Specifically, the corresponding controller (used to achieve communication connection with other devices and control the display mechanism to display the corresponding content, etc.) and the sensor (such as a light sensor for collecting and acquiring light information inside and outside the vehicle) are arranged on the substrate layer, and the power supply and the electrical connection with other devices are realized through the conductive layer. In this way, the controller and the 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. Exemplarily, the controller (or processor) is installed on the conductive substrate layer of the display mechanism, which can be reverse mounted, that is, the pins or pads of the processor chip are directly contacted and connected with the corresponding connection points of the conductive layer on the conductive substrate layer; it can also be positive mounted, such as through 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 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 sunroof, including a sunroof body and a display mechanism as described above, wherein the display mechanism is arranged on the sunroof body.

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

[0059] Another embodiment of the present invention provides a vehicle, comprising the above display mechanism, and / or the above smart display sunroof.

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

[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 a display structure.

[0063] Specifically, in step 200, the display mechanism is obtained by stacking and connecting the optical modulation layer, the conductive substrate layer and the display layer in sequence. Among them, the display layer is used to display the corresponding content to meet the user's image display requirements for the car sunroof, etc. The conductive substrate layer is used to power the display layer, and to protect and support the display layer of the display mechanism, etc., so as to ensure the stability and reliability of the display layer and the display mechanism as a whole. At least one of the transparency and transmittance of the optical modulation layer itself is suitable for adjustment, so as to adjust the light passing through the optical modulation layer inside and outside the vehicle by adjusting the transparency and / or transmittance of the optical modulation layer, so as to adjust the display effect of the display mechanism as a whole, so as to optimize the display effect of the display mechanism as a whole and enhance the user experience. By stacking and connecting the optical modulation layer, the conductive substrate layer and the display layer in sequence, it is convenient to realize the thin design of the display mechanism, so that the thickness of the entire display mechanism and the sunroof using the display mechanism can be controlled within an extremely thin range, so as to reduce the impact of the display mechanism on the interior space of the vehicle and enhance the user's driving experience, etc.

[0064] In this way, the method of this embodiment is used to realize the manufacture of the display mechanism to obtain the required display mechanism; by setting the display mechanism on the sunroof body of the vehicle to display the 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 for connecting, protecting, supporting and powering the display layer of the display mechanism, so as to improve the stability and reliability of the display layer and the display mechanism as a whole, and ensure that the display mechanism can operate stably, especially for a running vehicle, the setting of the conductive substrate layer can ensure that the display mechanism can still operate stably in an adverse vehicle operating environment such as bumps. By stacking and connecting the optical modulation layer, the conductive substrate layer and the display layer in sequence, a display mechanism for displaying the content required by the user on the sunroof body of the vehicle is obtained, thereby enriching the functionality of the vehicle sunroof, meeting the user's personalized and customized needs for the image display of the car sunroof, and facilitating the realization of a 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 the conductive substrate layer, and the optical modulation layer, the conductive substrate layer and the display layer are sequentially stacked and connected to obtain a display mechanism; or, the prepared optical modulation layer, the conductive substrate layer and the prepared display layer are sequentially stacked and connected to obtain a display mechanism.

[0067] Specifically, in order to enrich the functionality of the display mechanism and the sunroof of the vehicle using the display mechanism and optimize the display effect of the display mechanism, an optical modulation layer with adjustable transparency and / or transmittance is prepared for 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 the arrangement of the corresponding device of the display layer on the conductive substrate layer, the electrical connection between the display layer and the conductive layer of the conductive substrate layer, the connection between the display layer and the conductive substrate layer, etc.; the optical modulation layer, the conductive substrate layer and the display layer are stacked and connected in sequence to obtain the display mechanism. Among them, by preparing the display layer on the conductive substrate layer, the overall manufacturing process of the display mechanism is closely integrated, which is convenient for realizing and ensuring high-precision alignment and high-quality connection between the conductive substrate layer and the display layer, etc., and helps to better control the corresponding parameters in the production and manufacturing process of the display mechanism, and improve the consistency and quality of the product; the optical modulation layer, the conductive substrate layer and the display layer are stacked and connected in sequence, which is convenient for realizing the thin design of the display mechanism, so that the thickness of the entire display mechanism and the sunroof using the display mechanism can be controlled within an extremely thin range, so as to reduce the impact of the display mechanism on the interior space of the vehicle and enhance the user's driving experience.

[0068] Alternatively, after the preparation of the conductive substrate layer is completed, the pre-prepared optical modulation layer, the conductive substrate layer and the pre-prepared display layer are sequentially stacked and connected to obtain the desired display mechanism. In this way, the manufacturing process of the conductive substrate layer, the optical modulation layer and the display layer can be carried out step by step and independently, such as the manufacturing process of the conductive substrate layer, the manufacturing process of the optical modulation layer and the manufacturing process of the display layer can be completed on different production lines respectively, so as to improve the efficiency and flexibility of production and manufacturing. Among them, the optical modulation layer, the conductive substrate layer and the display layer are sequentially stacked and connected, which facilitates the thin design of the display mechanism, so that the thickness of the entire display mechanism and the sunroof using the display mechanism can be controlled within an extremely thin range, so as to reduce the impact of the display mechanism on the interior space of the vehicle and enhance the user's driving experience.

[0069] Optionally, before the prepared optical modulation layer, conductive substrate layer and display layer are sequentially stacked and connected to obtain a display mechanism, the method for manufacturing a display mechanism further includes:

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

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

[0072] For the manufacturing method of the display mechanism, first, through step 100, a base material and a conductive material for preparing a conductive base layer are selected, and the conductive base layer is prepared based on the base material and the conductive material. The conductive base layer is used to protect and support the display layer of the display mechanism, so as to ensure the stability and reliability of the display layer and the display mechanism as a whole; and the conductive base layer is also provided with corresponding circuits for power supply and signal transmission of the display layer and corresponding devices, so as to ensure that the display mechanism can operate stably, 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: selecting a substrate material, and pre-treating the substrate material to obtain a substrate layer that meets preset performance requirements; wherein the substrate material includes one of polyethylene terephthalate, cycloolefin 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 base layer using the conductive material and a preset printing technology; wherein the conductive material includes one of metal nanowires, graphene, transparent conductive polymers, and oxide semiconductors, and the preset printing technology includes at least one of a printing technology and a coating technology;

[0076] Wherein, the conductive base layer comprises a base layer and a conductive layer.

[0077] Specifically, through step 110, a suitable substrate material is selected, and a corresponding pretreatment process (such as plasma treatment, primer coating treatment, etc.) is used to treat it to obtain a substrate layer that meets the preset performance requirements. Among them, the preset performance requirements include mechanical strength requirements, chemical stability requirements, etc. For example, the substrate layer that meets the preset performance requirements has good mechanical strength and chemical stability, so as to connect, protect, and support the display layer of the display mechanism, support the subsequent preparation and operation of the display layer and the conductive layer, and ensure the stability and reliability of the operation of the display mechanism. As for the type of substrate material, one of PET (polyethylene terephthalate), COP (cycloolefin polymer) and polyether sulfone (PES) can be used.

[0078] Through step 120, by selecting a suitable conductive material, a conductive layer including a conductive circuit for powering the display layer and corresponding devices, signal transmission, etc. is printed on the substrate layer using a conductive material and a preset printing technology (such as printing technology and coating technology). On the one hand, it is used to power the display layer and corresponding devices (such as corresponding sensors, etc.) and realize signal transmission between corresponding devices, etc., to ensure the normal operation of the display mechanism and the effective control of the display mechanism; on the other hand, it is ensured that the entire display mechanism has a thin thickness to reduce the space occupied by the display mechanism in the vehicle. Exemplarily, a material with good conductive properties is used as a conductor material, and a conductive line is formed on the substrate layer through a process such as printing or deposition, which is used to connect the display layer and the corresponding power supply, provide the required power signal for the display layer, and enable the display mechanism to emit light or display normally. In some embodiments, the conductive layer is also required to have a high transparency so as not to affect the view of the sunroof. As for the type of conductive material, one of metal nanowires (such as silver nanowires AgNWs), graphene, transparent conductive polymers (such as poly (3,4-ethylenedioxythiophene), referred to as PEDOT; or polyaniline (PANI)) and oxide semiconductors can be used.

[0079] Optionally, pre-treating the substrate material includes:

[0080] The base material is subjected to plasma treatment and primer coating treatment, wherein the primer used in the primer coating treatment comprises an acrylic or silane primer.

[0081] Specifically, in order to obtain a base layer that meets the preset performance requirements, the base material needs to be pretreated. Specifically, the base material is plasma treated to improve the surface properties of the base material, enhance the adhesion and wettability of the base material to other materials, and improve the performance and durability of the base material in specific application scenarios. Plasma treatment can also remove organic pollutants and impurities on the surface of the base material, making its surface cleaner, which is conducive to subsequent operations. The base material is primed, such as by dipping, spraying or brushing, and the base material is coated with a corresponding primer to react with the polar groups on the surface of the base material through covalent bonds to form a stable interface on the surface of the base material, thereby improving the stability of the obtained base layer. For the type of primer material used in the primer coating treatment, acrylic or silane primers can be used.

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

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

[0084] Specifically, the base material is first subjected to plasma treatment and then subjected to primer coating treatment, so that organic pollutants and impurities on the surface of the base material are removed by plasma treatment, making the surface cleaner and facilitating subsequent coating or bonding operations.

[0085] Optionally, printing a conductive layer including a conductive circuit on the substrate layer using a conductive material and a preset printing technique comprises:

[0086] A conductive layer is printed on the base layer using a conductive material and a preset printing technology, wherein the preset printing technology includes micro-contact printing or screen printing.

[0087] Specifically, based on the selected conductive material, a preset corresponding printing (or printing) technology (referred to as preset printing technology) can be used to achieve the arrangement of the conductive layer on the base layer, so as to achieve a more detailed and precise conductive layer structure (or conductive circuit structure), and reduce the overall thickness of the conductive layer and the display mechanism, that is, the entire display mechanism has a thinner thickness, so as to reduce the space occupied by the display mechanism in the vehicle, etc. Among them, the preset printing technology includes printing technologies such as micro-contact printing and screen printing.

[0088] Alternatively, a conductive layer is printed on the base layer using a conductive material and a preset coating technique, wherein the preset coating technique includes spray coating or roller coating.

[0089] Specifically, based on the selected conductive material, a preset corresponding coating technology (referred to as preset coating technology) can be used to achieve the setting of the conductive layer on the base layer to ensure the uniformity and conductive performance of the conductive layer. Among them, the preset coating technology includes coating technologies such as spraying technology and roller coating technology. Spraying technology can quickly cover a large area by uniformly spraying the conductive material onto the surface of the base layer under high pressure, and is suitable for applications requiring fine patterns or irregular surfaces; roller coating technology uniformly coats the conductive material on the base layer through a rotating roller, which is suitable for coating of large areas and flat surfaces, and can ensure the thickness consistency and surface smoothness of the coating.

[0090] Optionally, printing a conductive layer on the base layer using a conductive material and a preset printing technology includes:

[0091] A conductive circuit pattern is formed on a substrate by using photolithography technology, and a stamp material is added to cover the conductive circuit pattern and solidified to obtain a stamp;

[0092] The conductive material is coated on the raised area on the stamp corresponding to the conductive circuit pattern, and then the stamp material in the raised area is pressed onto the base layer through a preset printing technology, and baked for a preset time to obtain a conductive base layer.

[0093] Specifically, a conductive circuit pattern is formed on a substrate using photolithography technology, that is, a desired conductive circuit pattern is generated on a substrate (such as a silicon wafer, etc.) using photolithography technology, such as coating a photoresist on the substrate, and obtaining the desired circuit pattern through a development process after exposure, and these circuit patterns will serve as templates for coating conductive materials. After the conductive circuit pattern is formed on the substrate, a stamp material (such as PDMS (Polydimethylsiloxane, polydimethylsiloxane, or silicone rubber) etc.) is coated on the formed conductive circuit pattern, and the conductive circuit pattern is completely covered, and then the stamp material is cured through a curing process (such as ultraviolet light curing or thermal curing, etc.) to obtain a stamp corresponding to the conductive circuit pattern, and the surface of the stamp has a convex area matching the conductive circuit pattern. Afterwards, on the cured stamp, a conductive material is coated on the convex area corresponding to the conductive circuit pattern, and the conductive material can be in the form of conductive ink (such as conductive silver nanowire ink), conductive paste, etc., and uniformly covered on the convex area through a coating process. Finally, a preset printing technology (such as transfer printing or embossing printing, etc.) is used to emboss the raised area of ​​the stamp material coated with a conductive material onto the base layer, so that the conductive material is transferred from the stamp to the base layer to form a conductive layer consistent with the conductive circuit pattern; and the embossed base layer is 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 conductive properties of the conductive layer, thereby obtaining the desired conductive base layer.

[0094] In this way, the advantages of photolithography and printing technologies are combined, and the high-precision pattern generation capability of photolithography and the efficient transfer capability of printing are utilized to achieve high-precision and efficient manufacturing of the conductive layer. The conductive circuit pattern is formed by photolithography to ensure the accuracy of the circuit; the conductive material is efficiently transferred to the base layer through the coating and stamping of the stamp material, achieving precise molding of the conductive layer.

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

[0096] A self-luminous display layer is prepared on the conductive substrate layer, or a non-self-luminous display layer is prepared on the conductive substrate layer.

[0097] Specifically, a self-luminous display layer may be prepared on a conductive substrate layer, or a non-self-luminous display layer may be prepared on a conductive substrate layer.

[0098] Wherein, preparing a self-luminous display layer on a conductive substrate layer comprises:

[0099] Applying conductive glue at multiple designated positions of the conductive circuit on the conductive substrate layer, and fixing multiple light-emitting structures at the multiple designated positions respectively by the conductive glue, wherein one light-emitting structure is arranged at one designated position;

[0100] The conductive substrate layer after the light emitting structure is arranged is placed under a preset temperature and preset pressure environment to cure the conductive glue to obtain a display mechanism.

[0101] Specifically, for the preparation of the self-luminous display layer on the conductive substrate layer, for example, the conductive glue is precisely applied to a plurality of predetermined designated positions on the conductive substrate layer, and these positions are determined according to the design requirements and circuit patterns of the display layer, and are used to ensure that each light-emitting structure (such as self-luminous elements such as OLED and LED) can be correctly connected to the corresponding circuit of the conductive layer. Each light-emitting structure is placed at a designated position on the conductive substrate layer where the conductive glue has been applied, ensuring that each light-emitting structure can be in good contact with the conductive circuit. Thereafter, the conductive substrate layer where the light-emitting structure is arranged is placed under a preset temperature and pressure environment for curing treatment to ensure that the conductive glue is completely cured, the light-emitting structure is firmly fixed, and a reliable electrical connection is formed with the conductive circuit. Among them, the curing process is to harden the conductive glue by heating and pressurizing, thereby firmly fixing the light-emitting structure on the conductive substrate layer and ensuring stable conductive performance. The preset temperature and preset pressure are to set appropriate temperature and pressure conditions according to the characteristics of the conductive glue and the light-emitting structure, to ensure that the glue will not damage the light-emitting structure or the conductive substrate layer during the curing process.

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

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

[0104] Specifically, the touch layer is a layer that senses the user's touch operation, and can use capacitive or infrared touch technology. Exemplarily, 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, that is, the side close to the passenger (or the user in the car), so that the user can control the operating parameters and display content of the display mechanism through touch operation. In this way, the functionality of the smart display sunroof is further enriched, and the user interaction experience is enhanced. That is, the introduction of the touch layer enables the smart display sunroof to not only have a display function, but also provide an intuitive interaction method. Users can control the content displayed on the sunroof, adjust the brightness, select functions, etc. by touching, thereby improving the convenience of operation and user experience.

[0105] Optionally, when the display mechanism is provided with an optical modulation layer, in order to ensure that the adjustment effect of the optical modulation layer is not affected accordingly, the material used for the base layer is preferably a transparent material. Exemplarily, for step 110, the base material for the base layer should be selected to consider transparency, UV resistance, and scratch resistance, so as to ensure the corresponding effect while ensuring the driving comfort of the corresponding vehicle occupants; for example, optical grade PET (polyethylene terephthalate), COP (cycloolefin polymer) or polyether sulfone (PES) is selected as the transparent base material.

[0106] For ease of understanding, the following uses polyethersulfone (PES) as a base material for exemplary explanation. PES is a polymer material made by polycondensation of bisphenol A and dichlorodiphenyl sulfone. It is favored in high-end application fields for its excellent mechanical properties, heat resistance, transparency, and chemical corrosion resistance. PES materials remain stable under high temperature and strong light conditions and are ideal for car sunroofs. However, since the surface characteristics of PES film are not suitable for subsequent conductive layer applications, the PES film needs to be pretreated accordingly, such as plasma treatment of the PES film, and acrylic or silane primer coating is selected according to actual conditions.

[0107] For example, for plasma treatment, the main purpose of plasma treatment of PES film is to improve its surface properties, enhance its adhesion and wettability with other materials, so as to improve its performance and durability in specific applications; plasma treatment can remove organic pollutants and impurities on the surface of PES film, making its surface cleaner, which is conducive to subsequent coating or bonding operations. Among them, the molecular formula of PES film will not change substantially after plasma treatment, and only the surface of the material will be modified, rather than changing its chemical composition or molecular structure. Plasma treatment will introduce some new functional groups-polar groups (hydroxyl-OH) on the surface of PES film to make it more hydrophilic. These hydroxyl functional groups can enhance the adhesion of PES film to other materials by hydrogen bonding or covalent bonding with other materials. In some embodiments, the plasma treatment parameters are recommended as follows: gas flow rate is 0.5 (liters / minute), power is set at 400-600W, treatment atmosphere (argon, oxygen mixed gas), and treatment time is 2-5 minutes. For primer coating, silane primer can be used for coating for PES film, and the dilution ratio of silane primer can be 1:1. The primer can react with the polar groups on the surface of PES 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 is 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 selecting a metal nanowire (such as silver nanowire AgNWs) network with high transparency and excellent conductivity as the conductive layer. The silver nanowire network is prepared on a substrate layer (such as a PES substrate layer) by high-precision printing technology (such as microcontact printing, screen printing) to form a highly transparent and uniform conductive layer, which can also be carried out by spraying or roller coating. In some embodiments, in addition to metal nanowires, graphene, transparent conductive polymers (such as poly (3,4-ethylenedioxythiophene), referred to as PEDOT; or polyaniline (Polyaniline, PANI)) or oxide semiconductors can also be selected as conductive layer materials.

[0109] For ease of understanding, the preparation of the conductive layer is illustrated below using microcontact printing technology as an example. Microcontact printing technology can achieve high-resolution patterning at the micron level, which helps to achieve a more delicate and precise conductive layer structure. When the conductive layer is prepared using microcontact printing technology, the stamp is first prepared, and the pattern is formed on the silicon wafer using photolithography technology, and then PDMS (Polydimethylsiloxane, polydimethylsiloxane, or silicone rubber) is poured and cured to form a stamp; then the ink is loaded, and the conductive silver nanowire ink is applied to the raised pattern part of the stamp; then microcontact printing is performed, and the stamp is pressed steadily on the substrate through automated mechanical equipment to transfer the silver nanowire ink to form a conductive pattern. Among them, in microcontact printing, the printing pressure is very important, and the pressure range that can be used is 7 to 9KPa. Finally, baking is performed, such as baking at 150°C for about 30 minutes, to promote the curing and conductivity of the silver nanowires.

[0110] Optionally, for preparing a display layer on a conductive substrate layer, the following is an example of using micro-LEDs to prepare a self-luminous display layer. On the substrate layer, the micro-LEDs are embedded (the micro-LEDs are embedded in a conductive substrate composed of a substrate layer and a conductive layer to form a thin and uniform display layer; each LED can be individually controlled to achieve the display of complex patterns and dynamic visual effects, so that the skylight can display from simple monochrome patterns to complex dynamic images or videos). Specifically, the micro-LEDs are arranged by dispensing and fixing, and an appropriate amount of conductive glue (such as a silver paste-based conductive glue with high conductivity and reliability) is applied to the conductive circuit (or conductive layer), and then the micro-LEDs are pasted to the designated position. Among them, a precision dispensing machine can be used to apply an appropriate amount of conductive glue to the designated position of the conductive circuit. When using a dispensing machine to apply conductive glue, the parameters of the dispensing machine need to be set, including glue flow rate, pressure, movement speed of the dispensing head, etc.; glue flow rate refers to the speed at which the glue flows out of the dispensing machine nozzle or injection needle. The selection of flow rate should be determined according to the size and spacing of the micro LED and the conductive circuit to ensure that the glue can be evenly applied to the designated position of the conductive circuit; for micro LED dispensing, a smaller flow rate is usually required to accurately control the amount of glue dispensed, such as using a flow rate of 0.3ml / s. Pressure refers to the force applied by the dispensing machine to the glue, which affects the speed and uniformity of the glue flow. The selection of pressure should be determined according to the model of the dispensing machine and the viscosity of the glue; for micro LED dispensing, moderate pressure is usually required to ensure that the glue can flow out stably and form a uniform coating at the dispensing location. Excessive pressure may cause the glue to flow too fast or spray too far, resulting in poor dispensing effect, such as using a pressure of 200kPa. In addition, a microscopic robot can be used to precisely place the micro-LED at the glue dispensing position to ensure that each micro-LED is precisely placed and fixed to ensure uniform light distribution and high-resolution display effects; in the meantime, by adjusting the magnification and focal length of the robot's built-in microscope, the contact between the micro-LED and the conductive glue can be clearly observed, ensuring that the positive and negative poles of the LED are connected to the corresponding positions of the conductive circuit.

[0111] After completing the arrangement and dispensing of the micro LEDs on the substrate layer, place the substrate layer (such as a PES substrate layer) with the micro LEDs arranged on it on a heating plate, and set the temperature and pressure of the heating plate, such as setting the temperature to 100°C and the pressure to 0.4MPa, to ensure that the conductive glue can be quickly cured at an appropriate temperature, so that the conductive glue is firmly connected to the micro LED and the conductive circuit without damaging the substrate.

[0112] Each pixel (corresponding to each micro-LED) then needs to be electrically and optically tested to ensure the quality of the connection. Microscopic observation and automated inspection equipment can be used to check the placement and bonding quality of each LED.

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

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

[0115] The processor and sensor are integrated on the conductive substrate layer of the display mechanism. Specifically, the corresponding processor (used to realize communication connection with other devices and control the intelligent display sunroof to display corresponding content, etc.) and sensor (such as a sensor for collecting and acquiring light information inside and outside the vehicle) are set on the substrate layer, and power supply and electrical connection with other devices are realized through the conductive layer. In this way, the processor and sensor are 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.

[0116] Optionally, after the display mechanism and corresponding components are prepared, 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 display mechanism of the smart display sunroof can be powered by a corresponding power supply of the vehicle.

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

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

[0120] Specifically, in order to ensure the overall structural strength and stability of the display mechanism used to be assembled on the sunroof body, the corresponding display mechanism obtained needs to be packaged and reinforced to ensure its durability and applicability while maintaining sufficient strength and transparency. Exemplarily, the smart display sunroof is composed of a multi-layer structure, such as laminated glass, to achieve the following structure: glass + base layer + conductive layer + display layer + protective layer + glass, so as to protect the display mechanism. In some embodiments, since the LEDs and circuits used in the corresponding display layer cannot temporarily achieve 100% transparency, a color mixing mode can be used to perform corresponding color and structural depolarization on the inside of the glass, so that the passenger's perception of internal parts is reduced to a minimum, thereby improving the user experience.

[0121] Optionally, the display mechanism (such as an LED panel) can be directly prepared on the sunroof body, or the display mechanism can be first made, and then the display mechanism and the sunroof body can be integrated together through processes such as gluing or hot pressing. In some embodiments, the display mechanism and the sunroof body are detachably connected, such as by fasteners, buckles, magnetic suction, etc., to improve the convenience of installing and removing the display mechanism on the sunroof body, and enable the display mechanism to have multiple application scenarios, that is, the display mechanism can be used independently outside the vehicle environment.

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

[0123] The display mechanism prepared by the above display mechanism manufacturing method is installed on the sunroof body to obtain an intelligent display sunroof.

[0124] Specifically, the prepared display mechanism is installed on the corresponding position of the sunroof body to complete the manufacture of the smart display sunroof, thereby obtaining a smart display sunroof for displaying the corresponding content required by the user to meet the user's functional requirements 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 sunroof, based on the above intelligent display sunroof; the control method for the intelligent display sunroof includes:

[0126] Determine optimal operating parameters for the display mechanism to display the content to be displayed under the light information based on the acquired content to be displayed for the display mechanism and the light information inside and outside the intelligent display skylight;

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

[0128] Specifically, by setting a smart display sunroof on the vehicle, it is used to display the corresponding content required by the user (such as text, images, animations, videos, etc.) to meet the user's functional requirements for the image display of the car (or vehicle) sunroof. Specifically, the smart display sunroof includes a sunroof body and a display mechanism for being set on the sunroof body, and the smart display sunroof displays the corresponding content through the display mechanism. Exemplarily, the display mechanism is set on the inner side of the sunroof body (that is, the side of the sunroof body facing the inside of the car) to avoid the possibility of damage to the display mechanism due to long-term exposure to the environment outside the car.

[0129] For the control of the smart display sunroof, considering the difference in the content displayed by the display mechanism and the influence of the light inside and outside the smart 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 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 of the display mechanism (that is, the content to be displayed) and the light information inside and outside the smart 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, first obtain the content to be displayed by the display mechanism and the current light information inside and outside the smart display sunroof, and determine the operating parameters (recorded as the optimal operating parameters) suitable for the display mechanism to best display the content to be displayed (or the user can obtain the best viewing experience) under the current light information based on the content to be displayed and the light information; 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. Among them, the content to be displayed may come from the user. For example, the user transmits the content to be displayed that needs to be displayed by the display mechanism of the smart display sunroof to the smart display sunroof for display through a vehicle computer or mobile terminal and other devices connected to the smart display sunroof to meet the user's personalized and customized needs.

[0130] In this way, the method of this embodiment is based on a vehicle equipped with an intelligent display sunroof, and can display the content that the user needs to display in the intelligent display sunroof, so as to meet the user's personalized and customized needs for the image display of the car sunroof and enrich 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 display sunroof, the optimal operating parameters for the display mechanism to display the content to be displayed under the light information are determined, and the display mechanism is controlled to display the content to be displayed based on the optimal operating parameters. In this way, it is ensured that the display mechanism can obtain the best display effect under different light conditions, that is, it is ensured that the user can obtain the best viewing experience under different light conditions, and the optimized display of the intelligent display sunroof under different light conditions is realized, while meeting the personalized needs of users, etc., and improving the user experience.

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

[0132] Specifically, the operating parameters of the display mechanism include the display brightness, color contrast, transparency and light transmittance of the display layer, among which display brightness refers to the intensity of light emitted by the display layer, that is, the intensity or brightness level of the light generated by the display layer; by adjusting the display brightness, the visibility and clarity of the displayed content can be controlled, so that the corresponding content displayed by the display mechanism can be clearly visible under different light conditions, improving user experience and viewing comfort. Color contrast refers to the degree of contrast between different colors in the display layer, that is, the degree of difference between the colors displayed by the display layer; by optimizing the color contrast, the color vividness and realism of the displayed content can be enhanced, making images, text or videos more vivid and bright. Transparency indicates the degree of light transmission of the display layer, that is, whether the scenery behind the display layer can be clearly seen. The higher the degree, the more transparent the display layer is, that is, more light can pass through, and the scenery behind the display layer can be seen more clearly (such as the scenery outside the car is seen by the user inside the car through the display mechanism). The lower the degree, the more opaque the display layer is, that is, the amount of light passing through is reduced, and the scenery behind the display layer becomes unclear or even invisible. Adjusting the transparency can affect the light transmission inside and outside the sunroof, thereby adjusting the light illumination and light transmittance inside the car, providing a more comfortable in-car environment and viewing experience, etc. Transmittance indicates the ability of the display layer to transmit light, that is, the degree of light passing through the display layer. High transmittance means that more light can pass through the display layer, and low transmittance means that the display layer has a greater obstruction to light. By adjusting the transmittance, the degree of light transmission can be controlled to achieve the purpose of adjusting the light and visibility inside the car. In this way, by adjusting these operating parameters, the smart display sunroof can provide the best display effect under different light conditions, and obtain the corresponding optimal operating parameters, thereby improving user experience and driving comfort.

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

[0134] Specifically, the display layer may be a self-luminous display layer that displays the corresponding content. Among them, the self-luminous display layer (such as a display layer / display panel that uses self-luminous OLED or Micro LED and does not require a backlight) can emit light by itself, without the need for an external light source, and each pixel can independently control its luminous intensity and color to achieve high contrast and bright color display. In this way, a self-luminous display layer is used, and no additional backlight or frontlight layer is required, so that the self-luminous display layer can be thinner and more energy-efficient. The display layer can also be a non-self-luminous display layer and a light source (such as a backlight layer, a frontlight layer) adapted thereto. The non-self-luminous display layer (such as a display layer using LCD (Liquid Crystal Display) or electronic ink technology / electronic ink screen, etc.) does not emit light by itself, and needs to be combined with an external light source (backlight layer or frontlight layer) to enhance the viewing experience. Among them, if the side of the non-self-luminous display layer facing the user is set as the front side, and the side away from the user is set as the rear side, for the backlight layer and the frontlight layer, there are: the backlight layer is set on the rear side of the non-self-luminous display layer, and the non-self-luminous display layer is illuminated by light to make the content visible; the frontlight layer is set on the front side of the non-self-luminous display layer to provide additional lighting to improve visibility. Exemplarily, for the non-self-luminous display layer using LCD, it is combined with the backlight layer to emit light to achieve clear visibility of the corresponding display content; for the non-self-luminous display layer using electronic ink technology / electronic ink screen, it can be used under natural light, or it can be combined with the light emission of the frontlight layer to achieve clear visibility of the corresponding display content, for example, in an environment with low natural light intensity, the frontlight layer emits light to achieve clear visibility of the content displayed by the non-self-luminous display layer using electronic ink technology / electronic ink screen. In some embodiments, the frontlight layer of the display layer can be used to provide lighting for the interior of the vehicle, or the lighting fixtures in the vehicle can be used as the frontlight layer of the display layer. The display layer can also simultaneously use a self-luminous display layer and a non-self-luminous display layer (which can be used in combination with at least one of the backlight layer and the frontlight layer). For example, in combination with corresponding usage requirements, the display layer position can be partitioned, with a self-luminous display layer used in some positions and a non-self-luminous display layer used in some positions. This enables the combined use of the self-luminous display layer and the non-self-luminous display layer, further enriching the functionality of the smart display skylight and providing more options for the user's personalized customization of image display.

[0135] For operating parameters, the self-luminous display layer (such as OLED and Micro LED) can emit light by itself, and each pixel can independently control its luminous intensity and color. Therefore, the display brightness and color contrast of the display layer are the display brightness and color contrast of the self-luminous display layer. The non-self-luminous display layer (such as LCD or electronic ink screen) requires an external light source (backlight layer or front light layer) to illuminate the display content. The adjustment of the display brightness and color contrast of the display layer needs to adjust the corresponding parameters of at least one of the non-self-luminous 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, thereby affecting the display brightness of the display layer; the color contrast of the LCD screen can be achieved 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 of light blocking by the pixels, while the brightness of the backlight layer affects the overall light intensity. The combined adjustment of the two can achieve the adjustment of the color contrast. For electronic ink screens, lighting is usually provided by front light. Therefore, the adjustment of display brightness can also be achieved by adjusting the brightness of the front light layer. The adjustment of color contrast generally requires adjusting the display color of the electronic ink screen.

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

[0137] Specifically, the optical modulation layer is arranged between the conductive substrate layer and the sunroof body, and its own transparency and / or transmittance can be adjusted to adjust the intensity of light entering from the outside of the vehicle through the sunroof position, so as to ensure the best display effect of the smart display sunroof on the corresponding content and the best viewing experience of the user. Alternatively, when the smart display sunroof is not required to display the corresponding content, the transparency and / or transmittance of the optical modulation layer can be adjusted to achieve shading (corresponding to lower transparency and / or transmittance, which plays a role of shading, protecting privacy, etc. similar to sunshades) or improve the viewing experience of the sunroof (corresponding to higher transparency and / or transmittance). Accordingly, the conductive substrate layer (including the conductive layer and the substrate layer) adopts (high) transparent materials to ensure that light can pass through effectively, and to ensure that the adjustment of the transparency and / or transmittance of the optical modulation layer itself can directly act on the display layer or the inside of the vehicle. In some embodiments, the display mechanism also needs to adopt a structure with higher transparency (when no content is displayed) to ensure that the viewing experience of the sunroof can be improved by increasing the transparency and / or transmittance of the optical modulation layer when no content is displayed.

[0138] Exemplarily, the optical modulation layer may adopt a liquid crystal layer (such as a liquid crystal layer combined with an electronic control or a polymer dispersed liquid crystal (PDLC) film) or an electrochromic material to change its light transmittance according to the change of the electrical signal, control the light transmittance of the sunroof, and thus maintain a comfortable light environment or an optimal display environment in different light environments inside and outside the vehicle. For example, when the sunroof needs to display corresponding content intelligently, the optical modulation layer can be adjusted to a black substrate to minimize the impact of light outside the sunroof on the content display. In some embodiments, the optical modulation layer can adopt a diaphragm structure so as to smoothly fit on the sunroof body and reduce the space occupied in the vehicle.

[0139] Optionally, according to the acquired content to be displayed for the display mechanism and the light information inside and outside the intelligent display skylight, determining the optimal operating parameters for the display mechanism to display the content to be displayed under the light information includes:

[0140] Based on the acquired control instructions regarding the intelligent display sunroof, determine the to-be-displayed content corresponding to the control instructions.

[0141] The smart display sunroof can interact with the user or the corresponding device to display the corresponding content according to the corresponding instructions or input content to meet the user's personalized needs, etc. Specifically, according to the control instructions about the smart display sunroof that have been obtained, the control instructions can be input by the user based on the touch layer of the smart display sunroof, or based on the vehicle computer or the corresponding mobile terminal device that is connected to the smart display sunroof for communication. For example, the user can issue a voice control instruction based on the voice module of the vehicle computer, and the vehicle computer parses the voice control instruction and sends it to the smart display sunroof for execution; or, the smart display sunroof recognizes the corresponding content in the external device (such as a USB flash drive) according to the corresponding interface of the vehicle computer connected to it, and displays it according to the corresponding control instructions based on the recognized content; or, the user determines the content that needs to be displayed by the smart display sunroof and the control instructions for displaying the content based on the corresponding application on the mobile terminal through the mobile terminal (such as a mobile phone) that is connected to the smart display sunroof for communication.

[0142] For ease of understanding, the interactive mode of the smart display sunroof and the editable display content are illustrated below with the display content as an image. The pattern to be displayed on the smart display sunroof is determined by mobile phone software or the software that comes with the car computer, and converted into a format that can be recognized by the display mechanism for display. Specifically, it is necessary to first develop special software that runs on the vehicle computing platform (car computer) or on a mobile phone that communicates with the smart display sunroof. The software needs to have the functions of image file recognition and decoding, and can process common image formats such as JPEG, PNG, etc.; and develop image processing algorithms for smart display sunroofs to convert the read (or received) pattern files into a format that can be recognized and displayed by the LED display, which may include adjusting the image resolution, contrast, brightness, color format conversion, etc. For large-size images, segmentation processing is also required so that they can be displayed smoothly in different areas on the display mechanism. During interaction, such as content transmission and display, the image data processed by the corresponding software is transmitted to the smart display sunroof. After receiving the data, the controller (or processor) of the smart display sunroof identifies and decodes it, and then maps the obtained image data to each pixel of the display layer of the display mechanism, controls the brightness and color of each pixel, and thus presents the final image. Among them, the design of the corresponding software and algorithm needs to take into account the real-time performance, the stability of data transmission and the optimization of display effects, ensure the high efficiency and low latency of data transmission and processing, and provide a smooth and clear display effect. Moreover, the interface of the corresponding software should be designed to be user-friendly so that the driver or passenger can easily select and preview the pattern.

[0143] According to the content to be displayed and the acquired light information, optimal operating parameters of the display mechanism for displaying the content to be displayed under the light information are determined.

[0144] Specifically, based on the acquired content to be displayed and light information, the operating parameters (referred to as optimal operating parameters) that are suitable for the display mechanism to optimally 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 smart display sunroof, the smart display sunroof can be applied to natural light lighting, entertainment display or business presentation, providing passengers with multiple modes of visual experience.

[0146] Optionally, the shapes and sizes of the sunroofs may be different for cars of different models and sizes. In order to realize the smart display sunroof on cars of different models and sizes, the smart display sunroof can be customized according to parameters such as the specific shape and size of the sunroof.

[0147] Optionally, for the smart display sunroof control, an artificial intelligence (AI) algorithm can also be integrated to enable the smart sunroof to automatically adjust the display content according to user habits and preferences based on the hardware of the smart display sunroof and the vehicle hardware. For example, AI can predict and adjust the most appropriate display mode of the smart display sunroof by analyzing environmental data and user interaction.

[0148] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
