Description

Display component, system board and data transmission method Technical Field

[0001] The present disclosure relates to the field of vehicle-mounted display components, and specifically provides a vehicle-mounted display component, an instrument panel assembly, and a vehicle. The present disclosure also relates to the field of packaging, and in particular relates to a display system board, a display assembly, and a vehicle including the aforementioned display system board or display assembly. The present disclosure also relates to the field of data transmission, and in particular relates to a data transmission method and system for multiple vehicle-mounted devices, a vehicle-mounted multi-display drive system, a computer-readable storage medium, and a vehicle. Background Art

[0002] Existing vehicles feature a central control display and an instrument panel on the dashboard. Generally speaking, the central control display is typically located in the center of the dashboard for use by the driver and passengers, while the instrument panel is typically located on the dashboard, corresponding to the driver's seat, for the driver to view. However, existing central control display and instrument panel are separate entities, separated by a gap that prevents them from visually integrating, impacting the overall aesthetics of the cabin. Therefore, a new technical solution is needed in this field to address these issues.

[0003] In some scenarios, a vehicle is equipped with multiple onboard devices (such as displays, speakers, audio players, air conditioners, lights, etc.). These onboard devices use their own transmission systems and processing modules to transmit, receive, process, or drive the data required by the onboard device (for example, a display displays video data, an audio player plays audio data, etc.). This results in the use of multiple sets of related transmission hardware, such as a set of transmission lines, decompression components, processing chips, system boards, etc. for each onboard device, resulting in a large space occupation in the vehicle and high component costs.

[0004] The assembly process of a display generally involves folding and assembling the display screen and its system board, connecting them with flexible material at the folds. In cases where a curved screen is desired, the system board may also need to be curved, ensuring that the flexible material at each connection between the display screen and the system board maintains the same shape, preventing issues such as warping. However, curved system boards have inherent drawbacks, such as a loss of security for components soldered to the system board. If the system board were flat, the folding and assembly would cause varying degrees of deformation (e.g., warping) in the flexible material at different connections, impacting the overall assembly process and the resulting product. Summary of the Invention

[0005] The present disclosure aims to solve the above-mentioned technical problem, that is, to solve the problem that the existing central control display screen and the instrument panel cannot be visually integrated, resulting in insufficient overall aesthetics in the cabin.

[0006] In a first aspect, the present disclosure provides a vehicle-mounted display assembly, comprising: a first display unit, comprising a first display screen, which can be used for a central control display of a vehicle; a second display unit, which is located behind the first display screen, and the second display unit comprises two second display screens arranged side by side and at intervals along the width direction of the vehicle, wherein the second display screen facing the main cockpit can at least be used to display instrument data of the vehicle, wherein the projection of the first display screen in the longitudinal direction of the vehicle partially overlaps with the projections of the two second display screens in the longitudinal direction of the vehicle, so that when the second display screen is observed from the side front of the first display screen, the display area of ​​the second display screen remains continuous with the first display screen.

[0007] In the preferred technical solution of the above-mentioned vehicle-mounted display assembly, the interval between the two second display screens is a non-display area, and the projection of the non-display area in the longitudinal direction of the vehicle can be covered by the projection of the first display screen in the longitudinal direction of the vehicle.

[0008] In the preferred technical solution of the above-mentioned vehicle-mounted display assembly, the second display screen is constructed as a flat screen or a curved screen that is curved toward the rear.

[0009] In the preferred technical solution of the above-mentioned vehicle-mounted display assembly, the ratio of the arc lengths of the second display screen, the non-display area and another second display screen in the length direction of the second display portion is 4:1:4 to 5:1:5.

[0010] In the preferred technical solution of the above-mentioned vehicle-mounted display assembly, in the longitudinal direction of the vehicle, the arc length corresponding to the overlapping portion of the projection of the second display screen and the projection of the first display screen is greater than or equal to 100 mm.

[0011] In the preferred technical solution of the above-mentioned vehicle-mounted display assembly, the curvature radius of the second display screen is greater than or equal to 800 mm.

[0012] In the preferred technical solution of the above-mentioned vehicle-mounted display assembly, the length of the second display screen is greater than the length of the first display screen; and / or the width of the second display screen is less than the width of the first display screen.

[0013] In the preferred technical solution of the above-mentioned vehicle-mounted display assembly, the second display portion further includes a second housing, and the two second display screens are both mounted on the second housing.

[0014] In the preferred technical solution of the above-mentioned vehicle-mounted display assembly, the first display portion further includes a first frame portion arranged around the periphery of the first display screen, and the width of the first frame portion in the length direction of the first display portion is less than 6 mm.

[0015] In the preferred technical solution of the above-mentioned vehicle-mounted display assembly, the first display screen is tilted relative to the horizontal plane.

[0016] In the preferred technical solution of the above-mentioned vehicle-mounted display assembly, the first display screen and the second display screen are inclined at an angle.

[0017] In the preferred technical solution of the above-mentioned vehicle-mounted display assembly, the first display screen is located directly in front of the two second display screens.

[0018] In a second aspect, the present disclosure further provides an instrument panel assembly, which is equipped with the vehicle-mounted display component described in any one of the first aspects above.

[0019] In the preferred technical solution of the above-mentioned instrument panel assembly, the instrument panel assembly includes an instrument panel and a bracket, and the first display part is installed on the instrument panel by means of the bracket.

[0020] In a third aspect, the present disclosure further provides a vehicle, the vehicle comprising the vehicle-mounted display assembly described in any one of the first aspects above; or the vehicle comprising the instrument panel assembly described in any one of the second aspects above.

[0021] When any of the above-mentioned preferred technical solutions is adopted, the present disclosure replaces the existing instrument panel by providing a second display screen. The projection of the first display screen in the vehicle's longitudinal direction partially overlaps the projections of the two second display screens in the vehicle's longitudinal direction. This allows the display area of ​​the second display screen to remain continuous with the first display screen when the second display screen is viewed from the side and front of the first display screen, thereby visually integrating the first display screen and the two second display screens, thereby improving the overall aesthetics of the cabin. Furthermore, since the length of a single display screen increases with the length of the prior art, the present disclosure reduces production costs by providing two second display screens in place of a single display screen. Furthermore, since the second display unit is located behind the first display screen, the positional relationship between the two creates a sense of depth in the space, further improving the overall aesthetics of the cabin.

[0074] The preferred embodiments of the present disclosure are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present disclosure and are not intended to limit the scope of protection of the present disclosure.

[0075] It should be noted that, in the description of the present disclosure, terms such as "upper", "lower", "front", "back", "inside", and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present disclosure.

[0076] Furthermore, it should be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integrated connections; they can refer to mechanical connections, direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this disclosure based on the specific circumstances. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance.

[0077] As shown in FIGS. 1 to 7 , an embodiment of the present disclosure provides a vehicle-mounted display assembly, which includes a first display portion 1 and a second display portion 2 .

[0078] The first display unit 1 can be installed on the instrument panel 3. As shown in FIG1 and FIG2 , the first display unit 1 is located in front of the second display unit 2. As shown in FIG3 , the front view shape of the first display unit 1 is a rectangle.

[0079] As shown in Figure 4, the first display unit 1 includes a first display screen 11 and a first shell 12. The first display screen 11 can be used for the central control display of the vehicle. The first display screen 11 is located in front of the second display unit 2. As shown in Figure 3, the front view shape of the first display screen 11 is a rectangle. Specifically, the first display screen 11 is a 13 to 18-inch rectangular display screen.

[0080] It should be noted that the vehicle's central control display is understood to be able to display information such as time, temperature, date, audio and video, and can also display information from the multimedia control system as well as information from the electronic navigation system and reversing assistance system.

[0081] The second display unit 2 can be mounted on the instrument panel 3. As shown in Figures 1 and 2, the second display unit 2 is located behind the first display unit 1. Furthermore, the second display unit 2 is located behind the first display screen 11. Because the second display unit 2 is located behind the first display screen 11, the positional relationship between the two can create a sense of depth in space, further improving the overall aesthetics of the cabin. As shown in Figure 3, the second display unit 2 has a bar-shaped front view. The length of the second display unit 2 is greater than that of the first display unit 1; and / or the width of the second display unit 2 is less than that of the first display unit 1. Specifically, the width of the first display unit 1 is less than or equal to 220 mm, and the width of the second display unit 2 is less than or equal to 60 mm.

[0082] As shown in FIG7 , the second display unit 2 includes two second display screens 21 arranged side by side and spaced apart along the width direction of the vehicle. Since in the prior art, the longer a single display screen is, the higher the production cost is. The present disclosure reduces production costs by providing two second display screens 21 instead of a single display screen. The length of the second display screen 21 is greater than the length of the first display screen 11; and / or the width of the second display screen 21 is less than the width of the first display screen 11. The second display unit 2 also includes a second housing 22, wherein the second display screen 21 facing the main cockpit can be used to display the vehicle's instrument data and multimedia information, and the second display screen 21 facing the co-pilot can be used to display the vehicle's instrument data and / or multimedia information. Both second display screens 21 are located behind the first display unit 1. As shown in FIG3 , the front view shape of the second display screen 21 is a bar. Specifically, the first display screen 11 is a 20 to 28-inch bar display screen.

[0083] It should be noted that vehicle instrument data is understood to include the speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, coolant level warning light, fuel level indicator light, washer fluid level indicator light, charging indicator light, high and low beam indicator light, transmission gear indicator light, anti-lock braking system indicator light, power control indicator light and / or airbag warning light. Multimedia information is understood to include information such as time, temperature, date, audio and / or video.

[0084] As shown in FIG3 , the projection of the first display screen 11 in the longitudinal direction of the vehicle partially overlaps with the projection of the two second display screens 21 in the longitudinal direction of the vehicle, so that when the second display screen 21 is observed from the front and side of the first display screen 11, the display area of ​​the second display screen 21 remains continuous with the first display screen 11, thereby visually integrating the first display screen 11 and the two second display screens 21, thereby improving the overall aesthetics of the cabin.

[0085] In some specific embodiments, as shown in Figures 3 and 4 , the first display unit 1 further includes a first frame portion 13 arranged around the periphery of the first display screen 11. The width of the first frame portion 13 along the length of the first display unit 1 is less than 6 mm. This arrangement minimizes the visual presence of the first frame portion 13 and does not affect the continuity of the display area of ​​the second display screen 21 with the first display screen 11. Furthermore, the visual impact of the first frame portion 13 can be reduced by displaying corresponding user interface images on the first and second display screens 11, 21, as a transition effect.

[0086] In some specific embodiments, the two second display screens 21 are both installed in the second housing 22 .

[0087] As shown in Figures 3 and 7 , the space between the two second display screens 21 is a non-display area 23. The projection of the non-display area 23 along the length of the vehicle is covered by the projection of the first display screen 11 along the length of the vehicle. It should be noted that the non-display area 23 is understood to be the area of ​​the non-display structure between the two second display screens 21, which cannot be illuminated. When observing the second display unit 2 from the front and side of the first display screen 11, the first display screen 11 can block the non-display area 23, thereby visually integrating the first display screen 11 with the two second display screens 21.

[0088] In some specific embodiments, the second display screen 21 is configured as a flat screen.

[0089] In some specific embodiments, the second display screen 21 is configured as a curved screen that curves toward the rear. This configuration allows the second display screen 21 to provide a better viewing angle, ensuring that the display area of ​​the second display screen 21 remains continuous with the first display screen 11. Furthermore, the second display screen 21 provides a sense of envelopment for passengers in the cabin, further enhancing the overall aesthetics of the cabin.

[0090] As shown in FIG3 and FIG7 , the ratio of the arc lengths of the second display screen 21 , the non-display area 23 and the other second display screen 21 is 4:1:4 to 5:1:5.

[0091] In some specific embodiments, the arc lengths of the second display screen 21 , the non-display area 23 and another second display screen 21 are 600 mm, 150 mm and 600 mm respectively.

[0092] In some specific embodiments, in the longitudinal direction of the vehicle, an arc length corresponding to an overlapping portion of the projection of the second display screen 21 and the projection of the first display screen 11 is greater than or equal to 100 mm.

[0093] In some specific embodiments, the curvature radius of the second display screen 21 is greater than or equal to 800 mm; when the curvature radius is infinite, the second display screen 21 structurally approaches an infinitely flat screen.

[0094] In some specific embodiments, the arc length of the second display portion 2 is greater than or equal to 1400 mm.

[0095] In some specific embodiments, the first display screen 11 is tilted relative to the horizontal plane. Specifically, as shown in FIG5 , the angle α between the first display screen 11 and the horizontal plane is less than 90°.

[0096] In some specific embodiments, the first display screen 11 is perpendicular to the horizontal plane.

[0097] In some specific embodiments, the first display screen 11 is tilted at an angle to the second display screen 21. Specifically, as shown in FIG6 , the angle between the first display screen 11 and the second display screen 21 is β.

[0098] In some specific embodiments, the first display screen 11 and the second display screen 21 are parallel to each other.

[0099] In some specific embodiments, as shown in FIG. 3 , the first display screen 11 is located directly in front of the two second display screens 21 .

[0100] In some specific embodiments, the first display screen 11 is located obliquely in front of the two second display screens 21 .

[0101] An embodiment of the present disclosure further provides an instrument panel assembly, which is equipped with any of the above-mentioned vehicle-mounted display components.

[0102] The instrument panel assembly includes an instrument panel 3 and a bracket 4 , and the first display unit 1 is mounted on the instrument panel 3 by means of the bracket 4 .

[0103] An embodiment of the present disclosure further provides a vehicle, the vehicle including any of the above-mentioned on-board display components; or the vehicle including any of the above-mentioned instrument panel assemblies.

[0104] The vehicle also includes a cockpit, which is equipped with any of the above-mentioned vehicle-mounted display components or any of the above-mentioned instrument panel assemblies.

[0113] In step S1, the data to be received by each of the multiple in-vehicle devices is combined. In some examples, for example, in-vehicle devices of the same type may receive the same type of data (e.g., video data). Therefore, the data to be received by each in-vehicle device can be combined to facilitate subsequent transmission and other processing using a common transmission system and a common processing system. Of course, different types of in-vehicle devices or data types can also be combined based on the technical requirements of specific application scenarios.

[0114] In step S2, the combined data is compressed using the same serializer (SER). The combined data is transmitted to the serializer via the same transmission line and compressed in the serializer so as to transmit the data in a smaller amount, which is beneficial to the rapid transmission of data.

[0115] In step S3, the compressed combined data is decompressed and split using the same deserializer (DES), and the split data is input to the data implementation end of the corresponding vehicle-mounted device. After passing through the serializer, the combined and compressed data enters the deserializer for decompression and splitting. The combined data is split in a similar manner to the combined data (for example, if the video data is spliced ​​frame by frame during combination, the splitting is also frame by frame) to restore the pre-combined data and transmit it to the data implementation end of the corresponding vehicle-mounted system.

[0116] In this way, it is possible to share a set of transmission, compression, decompression, and control solutions between multiple on-board devices of the same or different types. For example, a set of serial / deserialization links (SER / DES) can be shared, the same transmission data signals and lines can be shared, a system board can be shared to arrange the aforementioned serial / deserialization links and other hardware and modules that are common to multiple on-board devices, and the same main control chip (such as the main control unit MCU, etc.) can be shared. Compared with each on-board device independently using a set of the above hardware, this greatly reduces the space occupied by the hardware layout in the vehicle and the cost of many hardware facilities. In addition, it also reduces the complexity involved in the system.

[0117] In some embodiments, multiple in-vehicle devices can use the same data processing terminal, with the deserializer installed in the data processing terminal. For example, multiple displays can share a display system, which can be arranged on a system board (such as a PCBA hardware system board) and further use a deserializer and a main control chip. This further improves the system's integration and further reduces space usage and hardware costs.

[0118] In some embodiments, method 1000 may further include transmitting the split data to the data implementation end of the corresponding vehicle-mounted device via a functional safety module on the data processing end. In some implementations, it may be necessary to address functional safety issues with the data, such as implementing detection, verification, or correction of the transmitted data. Adding a functional safety module can enable these processing steps on the transmitted data, further ensuring the security of the data during implementation. In particular, in some examples, where one of the multiple vehicle-mounted devices has higher functional safety requirements, a functional safety module may be deployed for this vehicle-mounted device behind a shared system board or a shared deserializer.

[0119] In some embodiments, the method 1000 may further include: transmitting the split data that does not pass through the functional safety module to the data implementation end of the corresponding on-board device via a delay module on the data processing end. For the aforementioned data transmission via the functional safety module, one or some on-board devices that are applicable to the functional safety module may be delayed relative to other on-board devices that are not equipped with a functional safety module (for example, due to the delay in the functional implementation of the functional safety module itself, the delay of the lines and components, etc.). Therefore, for data that does not pass through the functional safety module, it can pass through the delay module on the data processing end, which can, to a certain extent, ensure that the data input to the on-board device that passes through the functional safety module and the on-board device that does not pass through the functional safety module are synchronized, or the delay amount difference is not too large. In some examples, the role of the delay module can be played by a bridge module for signal conversion to simultaneously complete signal conversion processing such as format and protocol conversion.

[0120] In some embodiments, as described above, the data processing end can use the same control module to control the deserializer and the data implementation end of each vehicle-mounted device. For example, a main control unit MCU is set in the shared data processing end to realize the control of data transmission (such as whether to transmit and the transmission rate, power, etc.). Therefore, the control module can be shared, and the shared control module can also be arranged on the same data processing end or the same system board, which is conducive to using the same control module when performing fault detection and control on multiple vehicle-mounted devices, which is more streamlined and also conducive to differentiated control and detection of multiple vehicle-mounted systems.

[0121] In some embodiments, the data implementation end of each of these multiple vehicle-mounted devices is provided with a timing synchronization control module. For example, a timing control T-con chip can be provided for each display screen end (i.e., the data implementation end of the display) to complete the timing control of the data implemented by the data implementation end. Further, in some examples, the data implementation end of each of these multiple vehicle-mounted devices can share a timing synchronization control module. In other words, components or modules can also be provided at the data implementation end to further reduce space occupancy and hardware costs. More importantly, the use of the same timing synchronization control can be based on the same timing control processing program, which is more conducive to achieving data alignment between the various data implementation ends, such as achieving alignment of video data playback between multiple displays.

[0122] It is understood that there are many ways to combine data, such as combining various sub-parts of the data. The basis for dividing the sub-parts can be determined by referring to the implementation effect of specific data. The data to be received by each of the multiple on-board devices includes multiple data units. The step of combining the data further includes: combining each data unit of each of the multiple on-board devices in the order of each on-board device. For example, the data to be received and implemented by on-board device A can be divided into a1, a2...a according to the receiving order. n The data units to be received and implemented by the vehicle-mounted device B can be divided into b1, b2...b according to the receiving order. n Data units, according to the order of each vehicle-mounted device, means that the data combination is a1b1, a2b2...a n b n The division of data units may refer to the characteristics of specific data, for example, for video data, it may be a single frame, for audio data, it may be a single sound wave pulse, and so on.

[0123] FIG11 shows a block diagram of a data transmission system 1100 for multiple on-board devices according to some embodiments. Similarly, the on-board devices may include a data processing terminal for processing data and a data implementation terminal for implementing data. The data transmission system 1100 for multiple on-board devices may include: a data combining device 1110 for combining data to be received by each of the multiple on-board devices; a serializer 1120 for compressing the combined data; a deserializer 1130 for decompressing and splitting the compressed combined data and inputting the split data into the data implementation terminal of the corresponding on-board device; a memory 1140 storing instructions; and a processor 1150 configured to execute the instructions to implement the data transmission method 1000 for multiple on-board devices described in any of the aforementioned embodiments. The data combination device 1110 may be, for example, a domain controller (e.g., a system-on-chip (SOC)) or an audio / video signal output module / unit on a controller of the vehicle, which has a data combination function and a corresponding algorithm. The data combination device 1110 may be, for example, disposed together with the serializer 1120 in a host (e.g., an onboard computer or a central control system). The descriptions of other modules or components are the same or similar to those described above regarding method 1000 and are not repeated here.

[0124] FIG12A shows a schematic diagram of a module of a vehicle-mounted multi-display driving system according to some embodiments. The vehicle-mounted multi-display driving system includes a host, a display system, and two display panels (for convenience, FIG12A shows two display panels (two displays), which can be understood as other numbers of display panels). The host (e.g., a vehicle-mounted computer) may include a system-on-chip (SOC) and a serializer. The system-on-chip (SOC) includes, for example, the data combining device described above, which is used to combine the video data to be received by each of the following multiple display panels (e.g., using the audio and video signal output module / unit on the SOC), and complete the splicing and combination of the data to be transmitted to each display panel for display. The serializer is used to compress the combined data and can, for example, provide other serializers for processing data. The display system may include a deserializer, which is used to decompress and split the compressed combined data, and, for example, can also perform other data processing operations of the deserializer. The deserializer inputs the split data one by one to the corresponding display panel. Multiple display panels are used to display according to the received video data. In such a vehicle-mounted multi-display driving system, the descriptions of many modules or components can be applied or appropriately modified according to the circumstances to be the same or similar to the aforementioned description of method 1000. The following only describes special application scenarios or functions in the vehicle-mounted multi-display driving system. Other parts refer to the above and will not be repeated here.

[0125] In some embodiments, the display system may further include a functional safety module, and the split data is transmitted to the corresponding display panel via the functional safety module. In some embodiments, it may be necessary to solve the functional safety problem of video data, such as realizing the detection, verification or correction of the transmitted video data. Adding a functional safety module as shown in Figure 12A can enable the transmitted video data to undergo these processes, further ensuring the safety and stability of these video data when displayed. For example, among multiple displays, there is a main driving screen with high functional safety requirements, which needs to ensure the real-time synchronous display of driving information and the stability of display performance. Therefore, a functional safety module can be arranged for the main driving display (screen) after a shared system board or a shared deserializer.

[0126] In some embodiments, the display system further includes a delay module, and the split data that does not pass through the functional safety module is transmitted to the data implementation end of the corresponding vehicle-mounted device via the delay module of the data processing end. For the aforementioned video data transmission via the functional safety module, the main driving display of the applicable functional safety module, for example, may be delayed relative to other displays that do not have a functional safety module (such as the co-pilot screen, the rear cabin screen) (for example, due to the delay in the functional implementation of the functional safety module itself, the delay of the lines and components, etc.). Therefore, for video data that does not pass through the functional safety module, it can pass through the delay module of the display system as shown in Figure 12A, which can ensure to a certain extent that the video display data input to the display that passes through the functional safety module and the display that does not pass through the functional safety module are synchronized, or the delay difference is not too large. In some examples, the role of the delay module can be played by a bridge module for signal conversion to simultaneously complete signal conversion processing such as video format and protocol conversion.

[0127] In some embodiments, each display panel of the plurality of display panels includes a timing synchronization control module for the timing synchronization of the video data received by the plurality of display panels. For example, a timing control T-con chip can be set for each display screen end (i.e., the data implementation end of the display) to complete the timing control of the data implemented by the data implementation end. Further, in some examples, the data implementation end of each of these multiple vehicle-mounted devices can share a timing synchronization control module. In other words, components or modules can also be set to be shared at the data implementation end in order to further reduce space occupancy and hardware costs. More importantly, the use of the same timing synchronization control can be based on the same timing control processing program, which is more conducive to achieving data alignment between the various data implementation ends, such as achieving alignment of video data playback between multiple displays.

[0128] In some embodiments, the display system may further include a main control unit for driving and controlling multiple display panels and deserializers. As shown in Figure 12A, between two displays, the main control unit MCU of the display system can be shared. As shown in Figure 12B, it shows a local module schematic diagram of the vehicle-mounted multi-display drive system according to some embodiments, which local includes a display panel part and a display system part, which is the same or similar to the above description of Figure 12A. In particular, the shared main control unit MCU shown in Figure 12B can realize the control of the timing synchronization control module (chip) arranged in each display panel and the control of the deserializer splitting data, and control the transmission rate, transmission power, etc. of the video data to control the display effect. The main control unit MCU can also, for example, realize the control of these two modules in a display system in which a functional safety module or a delay module is arranged, such as the enabling and disabling of each function of the functional safety module, the enabling and disabling of the delay module, and the adjustment of the delay amount, etc. In addition, the same main control unit is used to control the timing control of the deserializer and the display panel. The main control unit is connected to the gateway of the entire vehicle and can control the switching and brightness of the two display panels respectively. When a display panel fails, a separate main control unit MCU can also uniformly identify, detect, and report it and perform subsequent processing logic.

[0129] In some embodiments, the video data to be received by each of the plurality of display panels may include multiple frames, and the SOC is further configured to combine the video data by combining the single frames of each of the plurality of display panels in the order of each display panel. In some examples, the SOC utilizes its audio and video signal output module / unit to perform the above-mentioned sequential combination of frames. For example, the video data to be received and implemented by display A may be divided into a1, a2, ..., a1 according to the order of reception. n The video data to be received and implemented by display B can be divided into b1, b2...b according to the receiving order. n Frames, according to the order of each vehicle-mounted device, means that the data combination is a1b1, a2b2...a n b n .

[0130] Furthermore, in some embodiments, the video data to be received by each of the plurality of display panels includes a plurality of frames, each frame including a plurality of lines of pixel data, and the SOC is further configured to combine the video data by combining each line of pixel data of each frame of each of the plurality of display panels in the order of each display panel. That is, for example, the video data to be received and implemented by display A can be divided into a1, a2, ..., a1 according to the order of reception. nframes, each frame is divided into multiple lines (scanning lines, such as pixel scanning lines based on RGB pixel encoding), such as a1h1, a1h2, a1h3, ... a1h m ;a2h1, a2h2, a2h3,…a2h m ;a3h1, a3h2, a3h3,…a3h m ;…….a n h1、a n h2、a n h3, ...a n h m The video data to be received and implemented by display B can be divided into b1, b2...b according to the receiving order. n frames, each frame is divided into multiple lines (scanning lines, such as pixel scanning lines based on RGB pixel encoding), such as b1h1, b1h2, b1h3, ... b1h m ;b2h1, b2h2, b2h3,…b2h m ;b3h1, b3h2, b3h3,…b1h m ;…….b n h1, b n h2, b n h3,…b n h m According to the order of each vehicle-mounted device, the data combination is a1h1b1h1, a1h2b1h2, a1h3b1h3…a1h m b1h m , a2h1b2h1, a2h2b2h2, a2h3b2h3…a2h m b2h m , a3h1b3h1, a3h2b3h2, a3h3b3h3…a3h m b3h m ...a n h1b n h1、a n h2b n h2、a n h3b n h3…a n h m b n h m For example, it can be understood that after display A displays one line of a frame, display B displays one line of a frame, then display A displays the next line of the frame, and then display B displays the next line of the corresponding frame. In this way, because the data of multiple display times is combined, split, and distributed to the corresponding displays on a scan line basis in each frame, the timing synchronization of video data between displays can be further improved.

[0131] For example, taking a pixel as an example of a digital signal, each pixel has 1-10 or more bits (hereinafter, each pixel is exemplified as 1 bit), and each row has 10 pixels, so each row of pixels can be represented as a digital signal such as 1011010110. Furthermore, for more complex pixels, more pixel colors (such as RGB) can be represented by 8 bits each. Among them, the 0 / 1 bits of the digital signal can represent the high and low levels of the analog signal (such as a high level of 5V).

[0136] The above mainly describes the data transmission method and system for multiple vehicle-mounted devices, the vehicle-mounted multi-display drive system, the computer-readable storage medium, and the vehicle of the present disclosure.

[0141] FIG13 shows a schematic diagram of a display system board 100 according to some embodiments. The display system board 100 includes multiple connection areas 110 for folding and assembling with a display screen. Each of the multiple connection areas 110 is located at a plurality of distances from a first frame 120 on the display system board 100. The first frame 120 is the frame on the side of the display system board 100 that is folded and assembled with the display screen. The magnitude of each of the multiple distances is associated with the curve shape parameters of a second frame of the display screen. The second frame is the frame on the side of the display screen that is folded and assembled with the display system board 100.

[0142] For ease of description, the distribution of the various connection areas 110 (illustrated as six connection areas 110-1 through 110-6) shown in FIG13 is merely an example. It should be understood that the distribution of the connection areas 110 is not limited to the example shown in FIG13, but rather various locations and numbers of connection areas are applicable. Furthermore, the shape of the connection areas 110 is not limited to that shown in FIG13, but can be any shape, such as a rectangle, rhombus, parallelogram, circle, ellipse, or some irregular shape. The shape of the connection area can be determined based on the nature of the connection package in a specific embodiment. Furthermore, the connection area may not refer to a larger area, but rather a connection point (e.g., a solder joint) between the display screen and the system board 100, or, for example, an edge of a flexible connecting material connecting the display screen and the system board 100. The location or area where this edge is connected (e.g., soldered) to the system board can be referred to as the connection area 110.

[0143] The display system board can be assembled together with the display screen to form the main part of the display. Such a display system board can be, for example, a printed circuit board assembly PCBA board, on which various components for display can be arranged, such as a driver, a timing control unit (such as T-con), etc.

[0144] FIG13 shows the main planes of the display system board 100 and the display screen, wherein the display area of ​​the display screen is defined by the frame w1-w4. Correspondingly, the main plane of the display system board 100 is also defined by the frame w1-w4. The frame w1 of the display system board 100 is the first frame 120, and the frame w1 of the display screen is the second frame. Some components can be arranged on the main plane of the display system board 100, such as a driver for display, a module for timing control, etc. After the display system board 100 and the display screen are folded and packaged, the frame w1-w4 of the display system board 100 and the frame w1-w4 of the display screen are folded and assembled one by one to form a folded whole. Therefore, it can be understood that the display system board 100 and the display screen have basically the same shape and size, and the display screen has not been bent or otherwise processed at this time.

[0145] Each of the six connection areas 110-1 to 110-6 illustrated is at a certain distance from the first frame 120, such as the vertical distance between the center point (e.g., the geometric center point) of each connection area 110 and the first frame 120, the distance between the upper edge of each connection area 110 and the first frame 120, or other distances that characterize the positional relationship between the connection area 110 and the first frame 120. It will be understood that the two connection areas 110-1 and 110-6 at the outermost edges may be, for example, located directly on the first frame 120, or may have a slight distance from the first frame 120, even though for convenience of description, FIG. 13 may show the connection areas 110-1 and 110-6 as having a certain distance from the first frame 120.

[0146] It can be understood that the "border" of a display screen or display system board can be a virtual edge line (such as a display without a physical border) or a physical border area (such as the physical outer border of the display screen, the edge surface of the display, etc.).

[0147] Figures 14A-14C illustrate a display assembly 200 and its packaging process according to some embodiments. The display assembly 200 includes a display screen 220, a display system board 210 as described in any embodiment herein, and a plurality of flexible packaging chips 230. The plurality of flexible packaging chips 230 (illustrated as six, 230-1 through 230-6, corresponding to the connection areas 212-1 through 212-6 of the six display system boards 210) have the same shape and size and are, for example, produced using a unified production process. One end of each flexible packaging chip 230 is connected to the second bezel 222 of the display screen 220, and the other end is connected to a corresponding connection area of ​​the plurality of connection areas 212 of the display system board 210. In which, for example, the lower edge of each flexible package chip 230-1 to 230-6 is connected (e.g., welded) in the corresponding connection area 212-1 to 212-6 and is to be welded (as shown by the arrows in FIG14A ) to the corresponding position of the frame 222 (second frame) of the display screen 220 (e.g., the six illustrated dashed areas on the frame 222 in FIG14A ). The flexible package chips 230-3 and 230-4 (assuming that the upper edges of these two flexible package chips are aligned) extend beyond the first frame 214 by a length L1.

[0148] Flexible packaged chips can utilize, for example, chip-on-film (COF), which can be used to secure an integrated circuit (IC) to a flexible circuit board. Alternatively, a flexible additional circuit board can be used as a packaged chip carrier to combine the chip with a flexible substrate circuit. These COFs can include, for example, a flexible additional circuit board with an unpackaged chip, such as in tape-and-reel packaging, flexible board-to-chip assembly, flexible IC carrier packaging, or other COF formats suitable for display assembly.

[0149] FIG. 14B shows a state where the flexible package chips 230 - 1 to 230 - 6 are connected to corresponding areas on the second frame 222 . Among them, the flexible packaging chips 230-3 and 230-4 are in a normal length state (for example, normally straightened by the display system board 210 and the display screen 220). However, since the flexible packaging chips 230-1, 230-2, 230-5 and 230-6 are closer to the first frame 214 than the flexible packaging chips 230-3 and 230-4, while maintaining the distance between the display system board 210 and the display screen 220 at L2 as shown in FIG14B (it can be understood that L2 is equal to or similar to L1), the flexible packaging chips 230-1, 230-2, 230-5 and 230-6 will bend to varying degrees (or called warping, protrusion or depression, shown by the dotted line of the module 230 in the figure), and the degree of bending of the flexible packaging chips 230-1 and 230-6 is greater than that of the flexible packaging chips 230-2 and 230-5. That is, the closer the connection area is to the first frame, the greater the degree of bending of the corresponding flexible packaging chip.

[0150] Figure 14C shows a top view of the display assembly 200 after folding and assembly, with the display screen 220 bent. Based on Figure 14B , Figure 14C further bends the display screen 220 to form the desired curved screen. At this point, the flexible package chips 230-1, 230-2, 230-5, and 230-6, previously bent in Figure 14B , can be restored to their original state (i.e., to their normal length, like the flexible package chips 230-3 and 230-4). In some examples, the minimum distance between the curved screen (display screen) 220 and the display system board 220 (e.g., the distance from the intersection of the perpendicular midpoints of the first frame on the display screen 220 to the intersection of the display system board 220 in Figures 14A-14C) is configurable, and the positions of the various connection areas can be further designed based on the configured distance.

[0151] Thus, in some examples, after folding and assembling the display assembly 200 to form a curved screen, each flexible package chip 230 can maintain its normal length without bending the display system board 210. Each flexible package chip 230 can avoid bending (or significantly reduce the degree of bending). Therefore, the display system board 210 maintains a flat or substantially flat layout of components, avoiding the risk of disconnection (e.g., desoldering) or reduced connection strength of these components due to bending of the display system board 210. Furthermore, each flexible package chip adapts to the curved manufacturing of the display screen and remains flat after assembly. This avoids the additional space occupied by the flexible package chip due to bending, the risk of disconnection (e.g., desoldering) or reduced connection strength of components arranged on the flexible package chip, and the potential damage to the flexible package chip.

[0152] In addition, in some examples, this connection area position setting of the display system board can enable the production and assembly of each display assembly to use flexible packaging chips of the same size and shape, without having to use flexible packaging chips of different sizes and shapes on the same display component to adapt to the curved surface, which helps reduce the complexity of production or mass production.

[0153] Therefore, it can also be understood that in some embodiments, the positional distribution of each connection area of ​​the display system board (for example, represented by the distance of each connection area from the first bezel) can be associated with the corresponding display screen's bend-related geometric parameters (or curve shape parameters) for the upcoming bending process. Any such positional distribution of any connection area can also be represented by the distance of each connection area from the first bezel. Therefore, the relationship between the distances of each connection area from the first bezel can also represent this bend-related geometric parameter. For example, if the display screen is to be bent into an arc with a radius of r (i.e., the curved surface after forming the curved screen is an arc with a radius of r), then the corresponding distribution of connection areas on the display system board (for example, by stringing together the geometric center points of each connection area with a line) should also be the same or similar to this arc with a radius of r. This can further ensure that after the curved screen is formed, each flexible package chip is in a normal length state (e.g., all are straightened).

[0154] Furthermore, it can be considered that certain shape parameters of the distribution pattern of the connection areas can be substantially consistent with the shape parameters of the curved screen. For example, the curvature of the curved screen is substantially consistent with the curvature of the line formed by connecting the center points of each connection area. For another example, if the top view of the curved screen is an irregular line, then the line formed by connecting the center points of each connection area can also be substantially the same line as the irregular line. This depends on the shape parameters of the curved screen selected during the production or mass production of the display assembly, and is used to design and produce the display system board and its corresponding multiple connection areas.

[0155] It is understood that the term "substantially" or "substantially identical" may, for example, mean that certain shape parameters of the distribution diagram of the connection area can be identical to the shape parameters of the curve of the curved screen (i.e., two identical shapes). However, due to the limitations of actual production, it is impossible to achieve two identical shapes, so slight shape deviations are tolerable. Therefore, the terms "substantially" or "substantially identical" used throughout this document can be used to consider this impossibility of achieving exact sameness in actual production, meaning that slight differences (such as the aforementioned slight shape deviations, slight curve line deviations, slight position deviations, slight symmetrical distribution deviations, etc.) are within a tolerable range.

[0156] In some embodiments, as shown in FIG13 , the plurality of connection areas 110 may be symmetrically distributed about the perpendicular midline of the frame line of the first frame (e.g., the dotted line perpendicular to the first frame 120 in the figure). Furthermore, optionally, the distance from the first frame to the connection area 110 that is closer to the perpendicular midline of the frame line of the first frame (e.g., 110-2 is closer to the perpendicular midline than 110-1, and 110-3 is closer to the perpendicular midline than 110-2) is greater than the distance from the first frame to the connection area 110 that is farther from the perpendicular midline of the frame line of the first frame (e.g., 110-1 is farther from the perpendicular midline than 110-2, and 110-2 is farther from the perpendicular midline than 110-3). This facilitates the folding packaging of the current regular curved screen, and the curved line of the regular curved screen may also be substantially symmetrical about the perpendicular midline. As mentioned above, the number of connection areas or flexible packaging chips is not limited to 6, but can be other numbers, such as 10 (for example, 5 symmetrically distributed on both sides, or asymmetrically distributed depending on the specific shape of the curved screen to be formed), 13 (uniformly distributed or unevenly distributed along the first border, depending on the specific shape of the curved screen to be formed), 16, and so on.

[0157] In some embodiments, each of the plurality of connection areas is substantially rectangular. For example, it may be a long rectangular strip. It is understood that, when actually connected, the connection portion (e.g., soldering points, solder) between the flexible package chip and the display system board may take on various shapes and forms, but any connection portion may be confined to the connection area. Therefore, in some examples, such a connection area (e.g., an area surrounded by a groove or solid line) may be physically isolated on the display system board. Of course, it is also understood that it is not necessary to physically isolate such a connection area on the display system board, but the area of ​​the display system board to which the flexible package chip is connected may be considered a connection area, and such a connection area is the connection portion between the flexible package chip and the display system board (e.g., the area of ​​the solder joints, solder balls).

[0158] It is also understood that in some embodiments, the two connection areas closest to the ends of the first frame among the multiple connection areas are located on the first frame. For example, connection areas 110-1 and 110-6 in Figure 14A can be directly located on the first frame 120. This can provide the maximum degree of curvature for subsequent curved display manufacturing. Optionally, the connection area described herein includes an area (welding area) for welding the flexible package chip to the display system board.

[0159] In some embodiments, the shape parameters of the portion of the flexible package chip that connects to the second frame are substantially identical to the shape parameters of the corresponding portion of the second frame. Referring to FIG14C , it can be seen that the portion of any flexible package chip 230 that connects to the second frame is also curved. Therefore, the top edge of each flexible package chip 230 can have a similar line shape to that portion of the second frame. Such flexible package chips 230 can be manufactured identically and have the same size and shape, with only a slightly identical curve design applied to the top edge (taking the top edge 240 of flexible package chip 230-2 in FIG14C as an example) to achieve a more precise connection with the display screen and further reduce the degree of bending of the flexible package chip after folding and assembly. Of course, in certain scenarios where more precise control of the straightening of the flexible package chip is required (e.g., to further reduce the space occupied by the assembled component), such flexible package chips 230 can have different top edges, with each flexible package chip 230 individually adjusted to suit the shape of the corresponding portion of the second frame.
