[0032] In order to make the technical solutions in the specification clearer, the following will briefly introduce the drawings needed to be used in the description of the embodiments or prior art. Obviously, the drawings described below are only some embodiments described in the specification, and other drawings can be obtained by those skilled in the art without creative labor based on the embodiments in the specification.

[0033] The current starry roof technology has dynamic lighting transformation capability, which can create an immersive atmosphere through LED light source or flexible transparent screen, but its function is still limited to visual decoration, lacking practical information interaction with driving scene. In view of this limitation, the present application aims to propose a display scheme of vehicle starry roof, which can deeply integrate the starry roof and the navigation of the vehicle machine: through real-time positioning of the travel position of the vehicle in the navigation route, dynamically obtaining the relevant recommended information, and converting it into image content displayed on the starry roof, to meet the dual needs of visual sense and practical value of the user in the vehicle.

[0034] The display scheme of the vehicle starry roof of the present application will be described in detail below in combination with the embodiments.

[0035] Specifically, one embodiment of the present application provides a display method of a vehicle starry roof, Figure 1is a flowchart of the display method, comprising the following steps:

[0036] S102, determine the target navigation node in which the vehicle is currently located in the navigation route, wherein the target navigation node corresponds to a section of the navigation route.

[0037] The vehicle navigation is built-in with map data, including road network, traffic signs, buildings and other geographic information. When the destination is input, the navigation system will plan a route from the current location to the destination according to the map data, that is, the navigation route described in the text.

[0038] In this embodiment, the navigation route is segmented to divide multiple navigation nodes, and the navigation node in which the vehicle is currently located is defined as the target navigation node.

[0039] S104, determine the target recommendation information suitable for the target navigation node.

[0040] Based on the foregoing, the target navigation node is a section of the navigation route, and the target recommendation information related thereto can include place names, service facilities, scenic spots, etc. within or near the section.

[0041] In the specific implementation of this embodiment, the recommendation information can be divided into driver recommendation and passenger recommendation according to the identity of the occupant, and the two focus on different dimensions of travel demand:

[0042] 1) Driver recommendation information: focusing on improving driving safety and efficiency, which can include:

[0043] Place name information related to the navigation node (such as the name of the current section, intersection identification, bridge / tunnel name, etc.);

[0044] Service facility information related to the navigation node (such as real-time distance and accessibility of basic service facilities such as gas stations, charging piles, parking lots, repair stations, etc.);

[0045] Safety prompt information related to the navigation node (such as seat belt unfastening prompt, speed limit change ahead, congestion warning, accident-prone section prompt, etc.);

[0046] 2) Passenger recommendation information: focusing on optimizing leisure experience during the trip, which can include:

[0047] Tourist attraction information of the navigation node (such as the names and tours of cultural or natural scenic spots such as museums, parks, landmark buildings, etc.);

[0048] Point of Interest (POI) information of the navigation node (such as multi-dimensional information of catering, shopping, entertainment, etc.).

[0049] Correspondingly, this step can be determined by the seat sensor and / or the passenger monitoring system (OMS) of the vehicle, whether there is a passenger in the vehicle in addition to the driver.

[0050] If the vehicle only has a driver, only the driver recommendation information related to the target navigation node is determined as the target recommendation information; if the vehicle has both a driver and a passenger, the driver recommendation information and the passenger recommendation information related to the target navigation node are determined as the target recommendation information.

[0051] As a feasible implementation manner, the embodiment can extract the target recommendation information from the car navigation. The specific implementation logic is as follows:

[0052] I. Information source processing

[0053] Based on natural language processing (NLP) technology, the navigation information (such as "2km ahead to XX Zoo") of the car navigation is processed by text, involving the following steps:

[0054] 1. Semantic analysis: the navigation information (such as "2km ahead to XX Zoo") is segmented and semantically analyzed;

[0055] 2. Entity extraction: extract the key entity (such as "XX Zoo") in the navigation information;

[0056] 3. Type identification: according to the matching rules of the preset entity type (such as place name information, service facility information, scenic spot information and interest point information), the entity type corresponding to the key entity is matched (example: "XX Zoo" ➔ scenic spot information).

[0057] II. Structured information generation

[0058] Data integration: the navigation information is used as a context to attempt to supplement information for the key entity, and standardized target recommendation information is generated.

[0059] Example:

[0060] Input: navigation information "2km ahead to XX Zoo"

[0061] Output: {type: scenic spot, name: XX Zoo, distance: 2km}.

[0062] The above is an exemplary introduction to the driver recommendation information and the passenger recommendation information. In actual application, the driver recommendation information and the passenger recommendation information can contain information common to both, such as travel time information, travel distance information, etc., which will not be repeated here.

[0063] S106, based on the target recommendation information, generate a display scheme suitable for the starry roof of the vehicle, the display scheme being used by the starry roof to depict the target recommendation information in the form of an image.

[0064] Due to the sparse and uneven arrangement of light sources of the starry roof of the vehicle (such as a large LED dot array spacing), the physical structure cannot directly support the display of complex information. In order to ensure that the starry roof can effectively convey the recommendation information, the embodiment proposes a display method based on a simple line drawing image.

[0065] Specifically, the embodiment predefines a standardized image template library for different information content types, and each image template contains the following core elements:

[0066] 1) simple line drawing icon: an abstract and minimalist graphical symbol that adapts to the light source arrangement characteristics of the starry roof.

[0067] 2) label of information content type: clearly indicates the information content type to which the image template is applicable (such as scenic spots, service facilities, safety tips, etc.). For example:

[0068]

[0069] After determining the target recommendation information, the embodiment can select a target image template that matches the target recommendation information from the pre-configured image template library (mapping is achieved through the label of information content type, such as {type: aquarium} ➔ whale icon template), and render and supplement the configuration of the target starry roof image display template based on the target recommendation information, thereby generating a display scheme suitable for the starry roof.

[0070] The rendering and supplementary configuration is not limited to adding display colors and dynamic visual effects. In addition, if the light source arrangement of the starry roof supports simple character display, it can further include adding some important entities in the target recommendation information, such as travel distance information and travel time information, as shown in the following table:

[0071]

[0072] In summary, by introducing a simple line drawing image display template and combining appropriate rendering and supplementary configuration, the embodiment can enable the starry roof to convey recommendation information to in-vehicle users in a simple and intuitive manner, and the final display effect has the following characteristics:

[0073] 1) Intuitive: simple line drawing icons and color sets reduce the cognitive load of in-vehicle users, achieving "one glance" information transmission.

[0074] 2) Compatibility: adapts to different specifications of starry roof hardware (such as flexible screens and LED matrices).

[0075] 3) Interactivity: Dynamic effects (such as light flow, breathing) enhance the interest of the display scheme and improve passenger engagement.

[0076] S108, display the starry sky roof according to the display scheme.

[0077] This embodiment can send the data of the display scheme to the controller of the starry sky roof through the vehicle machine software interface, and the controller completes the display control of the starry sky roof. This process involves:

[0078] 1) Data transmission: the vehicle machine software interface sends the data of the display scheme to the controller of the starry sky roof through the LIN communication protocol or other communication methods.

[0079] 2) Control instruction generation: after receiving the data, the controller generates corresponding control instructions according to the display scheme. These instructions may include custom pattern setting signals, brightness control signals, dynamic display signals, etc.

[0080] 3) Display effect realization: the controller arranges display points in the display area of the starry sky roof through the connection of LED particles and optical fibers, forming a matching sketch image.

[0081] It should be noted that as long as the display capability of the starry sky roof light source structure is not exceeded, the above display effects can be realized by the existing controller.

[0082] In summary, the method of this embodiment first determines the target navigation node of the vehicle in the navigation route (i.e. the current journey), and based on the recommended information related to the target navigation node, configures the display scheme of the starry sky roof for depicting the recommended information in the form of an image. Then, the starry sky roof is controlled according to the display scheme to display accordingly, so as to intuitively present the recommended information to the in-vehicle user in a graphical manner. As the vehicle travels, the starry sky roof will continuously update the display of interesting information (such as scenic spots, service facilities, place names, etc.) matching the journey according to the real-time position, meeting the dual needs of in-vehicle users for visual experience and practical value.

[0083] In addition, since the starry sky roof is a multi-light source structure, frequent display of recommended information during vehicle travel will result in high power consumption. In order to solve this problem, this embodiment proposes the following two display management modes to balance the relationship between driving assistance, interesting experience and energy consumption.

[0084] Display management mode one

[0085] This embodiment divides the navigation route into a front navigation node (a journey just starting from the starting point), a middle navigation node (a journey in the middle) and a final navigation node (a journey approaching the destination), and adopts the following different display strategies according to different target navigation nodes.

[0086] The front navigation node and the end navigation node: when the vehicle travels to the front navigation node or the end navigation node, the star roof is displayed according to the display scheme corresponding to the driver recommendation information, regardless of whether there are other passengers in the vehicle. This design is mainly to provide necessary information support for the driver at the beginning and end of navigation, while avoiding the problem of high energy consumption caused by frequent display.

[0087] The middle navigation node: when the vehicle travels to the middle navigation node, if there are other passengers in the vehicle (i.e., the determined target recommendation information contains passenger recommendation information), the star roof is displayed according to the display scheme corresponding to the passenger recommendation information. This design takes into account the needs of passengers and improves the interest and immersion of interaction by displaying images or information related to the trip.

[0088] In actual application, the embodiment can divide the navigation route into different navigation nodes in the time dimension based on the trip planning time corresponding to the navigation route by the car navigation, or divide the navigation route into different navigation nodes in the distance dimension based on the trip planning distance corresponding to the target navigation node by the car navigation.

[0089] Taking the division of navigation nodes based on the time dimension as an example: the trip planning time of the navigation route can be equally divided according to the number of navigation nodes (including the front navigation node, the middle navigation node, and the end navigation node). For example, if the trip planning time is 9 minutes, and the front navigation node, the middle navigation node, and the end navigation node are to be divided, the first 3 minutes of the trip before the target navigation node is the front navigation node, the next 3 minutes of the trip is the middle navigation node, and the last 3 minutes of the trip is the end navigation node.

[0090] Taking the division of navigation nodes based on the distance dimension as an example: the trip planning distance of the navigation route can be equally divided according to the number of navigation nodes (including the front navigation node, the middle navigation node, and the end navigation node). For example, if the trip planning distance is 3 kilometers, and the front navigation node, the middle navigation node, and the end navigation node are to be divided, the first 1 kilometer of the trip before the target navigation node is the front navigation node, the next 1 kilometer of the trip is the middle navigation node, and the last 3 kilometers of the trip is the end navigation node.

[0091] The above is only an exemplary introduction to the division of navigation nodes in the time / distance dimension. In other implementation manners, 10% of the distance / time from the starting point to the entire navigation route can be defined as the front navigation node, 90% of the distance / time from the entire navigation route to the destination can be defined as the end navigation node, and the distance / time interval from 10% to 90% of the entire navigation route can be defined as the middle navigation node. It should be understood that these examples should not be considered as limiting the scope of protection of the present specification.

[0092] Display management mode two

[0093] Reference Figure 3 As shown in the figure, the embodiment further divides each navigation node into the following three sub-phases on the basis of dividing the navigation route into a plurality of navigation nodes:

[0094] The front navigation sub-node: the initial stage when the vehicle enters the navigation node;

[0095] The middle navigation sub-node (not limited to one): the middle stage when the vehicle is in the current navigation node;

[0096] The end navigation sub-node: the end stage when the vehicle is about to exit the current navigation node.

[0097] Based on the above division, the system executes differentiated star-top display strategies according to the specific position of the vehicle in the target navigation node and the state of the passengers in the vehicle:

[0098] 1) Display strategy of the front / end navigation sub-node

[0099] Applicable scenario: the vehicle enters the road section of the target navigation node or is about to switch to the road section of the next navigation node.

[0100] Display logic: by default, there is a driver in the vehicle, and no matter whether there are other passengers in the vehicle, the star-top is controlled to display according to the display scheme of the driver recommendation information preferentially or only, so as to ensure that the driving information is preferentially conveyed.

[0101] As can be seen, the driving stage of the front / end navigation sub-node focuses on direct support for the driver, such as prompting nearby charging piles or gas stations through the star-top.

[0102] 2) Display strategy of the middle navigation sub-node

[0103] Applicable scenario: the vehicle has traveled a certain distance or a certain time in the target navigation node.

[0104] Display logic: by default, there is a driver in the vehicle. If there are no other passengers in the vehicle, the star-top is no longer controlled to display, so as to save power and reduce the impact on the driver; if there are other passengers in the vehicle (i.e., the target recommendation information determined contains passenger recommendation information), the star-top is controlled to display according to the display scheme corresponding to the passenger recommendation information, so as to improve the passenger experience.

[0105] As can be seen, the driving stage of the middle navigation sub-node focuses on information interaction for passengers when there are passengers, and focuses on reducing power consumption when there are no passengers.

[0106] In actual applications, the embodiment can divide the target navigation node into corresponding navigation sub-nodes in a time dimension based on the travel planning time corresponding to the target navigation node by the car navigation device, or divide the target navigation node into corresponding navigation sub-nodes in a distance dimension based on the travel planning distance corresponding to the target navigation node by the car navigation device.

[0107] Taking the division of the navigation sub-nodes in the time dimension as an example, the travel planning time of the target navigation node can be equally divided according to the number of navigation sub-nodes (including the front navigation sub-node, the middle navigation sub-node, and the end navigation sub-node). For example, if the travel planning time is 12 minutes, and 1 front navigation sub-node, 2 middle navigation sub-nodes, and 1 end navigation sub-node are needed, the first 3 minutes of travel of the target navigation node can be determined as the front navigation sub-node, the travel from the 3rd minute to the 6th minute can be determined as the first middle navigation sub-node, the travel from the 6th minute to the 9th minute can be determined as the second middle navigation sub-node, and the last 3 minutes of travel can be determined as the end navigation sub-node.

[0108] Taking the division of the navigation sub-nodes in the distance dimension as an example, the travel planning distance of the target navigation node can be equally divided according to the number of navigation sub-nodes (including the front navigation sub-node, the middle navigation sub-node, and the end navigation sub-node). For example, if the travel planning distance is 4 kilometers, and 1 front navigation sub-node, 2 middle navigation sub-nodes, and 1 end navigation sub-node are needed, the first 1 kilometer of travel of the target navigation node can be determined as the front navigation sub-node, the travel from the 1st kilometer to the 2nd kilometer can be determined as the first middle navigation sub-node, the travel from the 2nd kilometer to the 3rd kilometer can be determined as the second middle navigation sub-node, and the last 1 kilometer of travel can be determined as the end navigation sub-node.

[0109] Similarly, the above is only an exemplary introduction to the division of the navigation sub-nodes in the time / distance dimension. In other implementation manners, 20% of the distance / time of the entire navigation route from the starting point can be defined as the front navigation node, 80% of the distance / time of the entire navigation route to the destination can be defined as the end navigation node, and the distance / time interval of 20% to 80% of the entire navigation route can be defined as the middle navigation node. It should be understood that these examples should not be regarded as a limitation on the protection scope of the present specification.

[0110] In summary, in the above two display management modes, the embodiment distinguishes and displays the recommended information according to the driver and the passenger, thereby achieving the following advantages:

[0111] 1) Precision: driving assistance information is provided to the driver at driving key nodes of the trip, and interesting information is provided to the passenger at non-driving key nodes; the two types of information are displayed staggered, avoiding exceeding the display capability of the starlight roof light source structure.

[0112] 2) Safety: When there is no passenger, the star-top display is no longer activated at non-driving critical nodes, thus reducing the distraction to the driver's attention.

[0113] 3) Energy efficiency optimization: When there is no passenger, the star-top display is no longer activated at non-driving critical nodes, thus saving power consumption.

[0114] The method of the embodiment will be introduced below in combination with application scenarios.

[0115] Application scenario one

[0116] This application scenario integrates the star-top recommended information display function into the car machine system, and the user can actively enable it through manual, voice or gesture interaction. The implementation process is divided into the following two stages:

[0117] I. Information preparation stage

[0118] 1) Navigation route determination: When the car machine navigation is started, the current planned route is automatically obtained.

[0119] 2) Navigation node division: According to the travel planning time of the navigation route, the navigation route is further divided into multiple navigation nodes with equal time (such as 2 minutes).

[0120] Among them, the navigation nodes at least include: the front navigation node, the middle navigation node and the end navigation node.

[0121] The front navigation node can be the first navigation node in the navigation route, the end navigation node can be the last navigation node in the navigation route, and the middle navigation node can be the remaining navigation nodes in the navigation route.

[0122] 3) Passenger identity recognition: Through the seat sensor of the vehicle, it is identified whether there is a passenger in the vehicle except the driver.

[0123] Among them, the seat sensor can include: seat weight sensor and seat belt sensor.

[0124] For the use of seat weight sensor, the weight of passenger seat can be detected through the seat weight sensor of each passenger seat. If the weight of any passenger seat reaches a preset threshold (such as ≥20kg), it is determined that there is a passenger in the vehicle except the driver; otherwise, it is determined that there is only the driver in the vehicle.

[0125] For the use of seat belt sensor, whether the passenger seat is buckled up can be detected through the seat belt sensor of the passenger seat. If any passenger seat is buckled up, it is determined that there is a passenger in the vehicle except the driver; otherwise, it is determined that there is only the driver in the vehicle.

[0126] 4) Recommended information generation: based on the map data of the car navigation, configure recommended information suitable for the corresponding passenger identity for each navigation node.

[0127] Among them, the recommended information is specifically divided into:

[0128] ① Driver recommended information applied to the front navigation node and the end navigation node, including related place name information, service facility information and safety prompt information, etc.

[0129] For example, if the place name information is selected for recommendation at the end navigation node, the destination guidance can be focused on; if the safety prompt information is selected for recommendation at the front navigation node (such as a reminder that the seat belt is not fastened), the safe driving can be focused on.

[0130] ② Passenger recommended information applied to the middle navigation node, including related scenic spot information and interest point information, etc.

[0131] Among them, the scenic spot information can be an aquarium, a zoo, a botanical garden, a museum, an amusement park, etc.; the interest point information is a function that most navigation software comes with, recording various types of information that users may be interested in, such as restaurants, food and culture, etc. It should be understood that selecting scenic spot information and / or interest point information for recommendation at the middle navigation node can focus on passenger experience.

[0132] It should be noted that the information preparation stage of this application scenario can re-complete the configuration of navigation nodes, navigation sub-nodes and recommended information when the car navigation plans to update the navigation route, so as to ensure that the recommended information is matched with the navigation route in real time.

[0133] II. Information application stage

[0134] 1) Real-time positioning of target navigation node: determine the target navigation node in the current navigation route of the vehicle from the car navigation. This process is consistent with the real-time positioning function provided by the car navigation, and the system will dynamically update the target navigation node according to the current position of the vehicle.

[0135] 2) Display scheme generation: when the vehicle enters the target navigation node, generate a display scheme suitable for the star roof according to the recommended information corresponding to the target navigation node.

[0136] Specifically, the car machine system can pre-configure image templates for recommended information of different information content types, and the image templates contain simple sketch images that meet the characteristics of the information content type, so as to be suitable for display on the star roof.

[0137] For example, the image template corresponding to the passenger recommended information can be as shown in the following table:

[0138]

[0139] After determining the target recommendation information, a target image template matching the target recommendation information can be selected from pre-configured image templates, and the target starry sky top image display template is rendered and supplemented based on the target recommendation information (such as adding display colors, dynamic visual effects, etc.), so as to generate a display scheme suitable for the starry sky top.

[0140] It should be understood that the above image templates can be continuously updated through upgrading of the vehicle machine system, which will not be described here.

[0141] 3) Starry sky top display control: control the starry sky top to display according to the generated display scheme.

[0142] The display control logic is as follows:

[0143] If the target navigation node is a front segment navigation node or a last segment navigation node, the starry sky top is controlled to display according to the display scheme corresponding to the driver recommendation information when the vehicle travels to the target navigation node and the driver recommendation information is determined. It should be noted that if the driver recommendation information is not determined, there will be no display scheme for the front segment navigation node or the last segment navigation node, and in this case the starry sky top is not activated to save power.

[0144] If the target navigation node is a middle segment navigation node, the starry sky top is controlled to display according to the display scheme corresponding to the passenger recommendation information when the vehicle travels to the driver recommendation information node and the passenger recommendation information is determined. Similarly, if the passenger recommendation information is not determined, there will be no display scheme for the middle segment navigation node, and in this case the starry sky top is not activated to save power.

[0145] Application scenario two

[0146] This application scenario integrates the recommendation information display function of the starry sky top into the vehicle machine system, and the user can actively enable it through manual, voice or gesture interaction. The implementation process is divided into the following two stages:

[0147] I. Information preparation stage

[0148] 1) Navigation route acquisition: When the vehicle machine navigation is started, the current planned navigation route is automatically acquired from the vehicle machine navigation.

[0149] 2) Navigation node division: The navigation route is divided into multiple navigation nodes, and each navigation node corresponds to a segment of the navigation route.

[0150] Among them, the division method of the navigation node is not unique, and is not limited to:

[0151] User manual division: Users can manually add or delete navigation nodes of the route through the touch control vehicle machine operation interface to meet individual needs. For example, in a complex urban road network, users can manually adjust the nodes to optimize the arrangement of navigation nodes.

[0152] System automatic division: The vehicle machine system automatically generates navigation nodes based on preset rules to analyze the topology of the navigation route at the road granularity. For example, the vehicle machine system can define the entrance to the exit of the highway as a navigation node.

[0153] 3) Navigation sub-node division: For each navigation node, a plurality of navigation sub-nodes with equal distances are divided according to the corresponding trip planning distance.

[0154] Among them, the divided navigation sub-nodes at least include: front navigation sub-node, middle navigation sub-node and end navigation sub-node.

[0155] The front navigation sub-node can be the first navigation sub-node in the navigation node, the end navigation node can be the last navigation sub-node in the navigation node, and the middle navigation node can be the remaining navigation sub-node in the navigation node.

[0156] 4) Passenger identity recognition: Through the passenger monitoring system of the vehicle, it is identified whether there are passengers in the vehicle in addition to the driver.

[0157] Among them, the passenger monitoring system will be configured with a camera inside the vehicle, which can collect the picture of each passenger seat through the camera, and combine the deep learning model to detect the collected picture. If the detection result of any passenger seat indicates that it is a human body, it is determined that there are passengers in the vehicle in addition to the driver. Otherwise, it is determined that there is only a driver in the vehicle.

[0158] 5) Recommended information generation: For each navigation node, based on the map data of the vehicle navigation, all navigation sub-nodes are configured with recommended information suitable for the corresponding passenger identity.

[0159] Among them, the recommended information is specifically divided into:

[0160] ① The driver recommended information applied to the front navigation sub-node and the end navigation sub-node, including related place name information, service facility information and safety prompt information, etc.

[0161] ② The passenger recommended information applied to the middle navigation sub-node, including related scenic spot information and interest point information, etc.

[0162] It should be noted that the information preparation stage of this application scenario can be completed again when the vehicle navigation planning updates the navigation route, and the configuration of the navigation node, the navigation sub-node and the recommended information, so as to ensure that the recommended information is matched with the navigation route in real time.

[0163] II. Information application stage

[0164] 1) Real-time positioning target navigation node: determine the target navigation node in which the vehicle is currently navigating from the car navigation, and specifically locate the navigation sub-node in which the vehicle is located in the target navigation node.

[0165] 2) Display scheme generation: when the vehicle enters the target navigation node, generate a display scheme suitable for the star top according to the recommended information corresponding to the specific navigation sub-node.

[0166] Specifically, the car machine system can pre-configure image templates for recommended information of different information content types, and the image templates contain simple sketch images that meet the characteristics of information content types, suitable for display on the star top.

[0167] After determining the target recommended information, the target image template matching the target recommended information can be selected from the pre-configured image template, and the target star top image display template is rendered and supplemented (such as adding display color, dynamic visual effect, etc.) based on the target recommended information, thereby generating a display scheme suitable for the star top.

[0168] It should be understood that the above-mentioned image template can be continuously updated through the upgrade of the car machine system, which will not be described here.

[0169] 3) Star top display control: control the star top to display according to the generated display scheme.

[0170] Among them, the display control logic is as follows:

[0171] If the vehicle travels to the front or end navigation sub-node of the target navigation node, and the driver's recommended information is determined, the star top is displayed according to the display scheme of the driver's recommended information; it should be noted that if the driver's recommended information is not determined, there will be no display scheme for the front or end navigation sub-node, in this case the star top is not activated to save power.

[0172] If the vehicle travels to the middle navigation sub-node of the target navigation node, and the passenger's recommended information is determined, the star top is displayed according to the display scheme of the passenger's recommended information; similarly, if the passenger's recommended information is not determined, there will be no display scheme for the middle navigation sub-node, in this case the star top is not activated to save power.

[0173] In addition, corresponding to the method shown in Figure 1 According to another embodiment of the present application, a display device for a vehicle star top is also provided. Figure 4 is a structural schematic diagram of the display device 400, which includes:
