[0018] Figure 2 This is a structural block diagram of another vehicle-mounted display system provided in this embodiment of the present utility model. Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0020] Figure 1 This is a structural block diagram of an in-vehicle display system provided in an embodiment of this utility model. (Reference) Figure 1 The vehicle-mounted display system includes: a vehicle-mounted screen module 10 and a vehicle-mounted drive module 20; wherein, the vehicle-mounted screen module 10 includes a display screen 11, a first wiring harness interface 12, and a first wireless communication unit 13, and the vehicle-mounted drive module 20 includes a vehicle-mounted processor 21, a second wiring harness interface 22, and a second wireless communication unit 23; the display screen 11 is electrically connected to the first wiring harness interface 12 and the first wireless communication unit 13, and the vehicle-mounted processor 21 is electrically connected to the second wiring harness interface 22 and the second wireless communication unit 23; the first wiring harness interface 12 and the second wiring harness interface 22 are electrically connected via a line, and the first wireless communication unit 13 and the second wireless communication unit 14 are communicatively connected; the vehicle-mounted processor 21 is used to transmit signals to the display screen through the second wireless communication unit 23 and the first wireless communication unit 13, or the vehicle-mounted processor 21 is used to transmit signals to the display screen through the second wiring harness interface 22 and the first wiring harness interface 12.

[0021] Specifically, when the wiring between the first wiring harness interface 12 and the second wiring harness interface 22 is normal, the vehicle infotainment processor 21 transmits signals to the second wiring harness interface 22, such as transmitting video signals and control signals to the first wiring harness interface 12 via a serializer. The second wiring harness interface 22 transmits the signals to the first wiring harness interface 12 through the connecting line between the second wiring harness interface 22 and the first wiring harness interface 12, and then the first wiring harness interface 12 transmits the signals to the display screen 11, such as transmitting the signals to the display screen 11 via a deserializer, so that the display screen 11 displays the video image. The vehicle infotainment processor 21 can be a system-on-chip (SoC) of the vehicle infotainment system. When a line fault occurs between the first wiring harness interface 12 and the second wiring harness interface 22, the vehicle processor 21 transmits signals such as video signals and control signals to the second wireless communication unit 14. The second wireless communication unit 14 transmits the signals to the first wireless communication unit 13 via wireless communication, and then the first wireless communication unit 13 transmits the signals to the display screen, ensuring that the display screen 11 can display normally. This prevents the display screen 11 from going black when a line fault occurs between the first wiring harness interface 12 and the second wiring harness interface 22, which would prevent the transmission of signals between the first wiring harness interface 12 and the second wiring harness interface 22.

[0022] The vehicle-mounted display system provided in this embodiment includes: a vehicle-mounted screen module and a vehicle-mounted driver module; wherein, the vehicle-mounted screen module includes a display screen, a first wiring harness interface, and a first wireless communication unit, and the vehicle-mounted driver module includes a vehicle-mounted processor, a second wiring harness interface, and a second wireless communication unit; the display screen is electrically connected to the first wiring harness interface and the first wireless communication unit, and the vehicle-mounted processor is electrically connected to the second wiring harness interface and the second wireless communication unit; the first wiring harness interface and the second wiring harness interface are electrically connected via a line, and the first wireless communication unit and the second wireless communication unit are communicatively connected; the vehicle-mounted processor is used to transmit signals to the display screen through the second wireless communication unit and the first wireless communication unit, or, the vehicle-mounted processor is used to transmit signals to the display screen through the second wiring harness interface and the first wiring harness interface. The vehicle display system provided in this embodiment allows the vehicle processor to transmit signals to the display screen via a second wireless communication unit and a first wireless communication unit, or the vehicle processor can transmit signals to the display screen via a second wiring harness interface and a first wiring harness interface. When there is a line fault between the second wiring harness interface and the first wiring harness interface, the vehicle processor transmits signals to the display screen via the second wireless communication unit and the first wireless communication unit to ensure that the display screen can display normally and prevent the display screen from going black due to the inability to transmit signals between the first wiring harness interface and the second wiring harness interface caused by the line fault.

[0023] Figure 2 This is a structural block diagram of another vehicle-mounted display system provided in an embodiment of this utility model. (Reference) Figure 2Optionally, the vehicle screen module 10 also includes a controller 14, which is electrically connected to the display screen 11 and the first wireless communication module 13. The controller 14 is used to communicate with the vehicle processor 21 through the first wireless communication module 13 and the second wireless communication module 23, or the controller 14 is used to communicate with the vehicle processor 21 through the first wiring harness interface 12 and the second wiring harness interface 22. The vehicle processor 21 is also used to drive the display screen 11 to work through the controller 14.

[0024] Specifically, the vehicle infotainment processor 21 transmits control signals to the controller 14 through the second wireless communication module 23 and the first wireless communication module 13, or the vehicle infotainment processor 21 transmits control signals to the controller 14 through the second wiring harness interface 22 and the first wiring harness interface 12. The first wireless communication module 13 and the controller 14 can be integrated into the same chip. The controller 14 drives the display screen 11 according to the received control signals, thus directly driving the display screen 11 instead of the vehicle infotainment processor 21, reducing the workload of the vehicle infotainment processor 21.

[0025] refer to Figure 2 Optionally, the vehicle screen module 10 also includes a deserializer 15. The first wiring harness interface 12 is electrically connected to the display screen 11 through the deserializer 15. The deserializer 15 is used to deserialize the serial signal transmitted by the first wiring harness interface 12 and then transmit it to the display screen 11.

[0026] Specifically, the signal transmitted from the second harness interface 22 to the first harness interface 12 is a serial signal, for example, a video signal. This serial signal is deserialized by the deserializer 15 before being transmitted to the display screen 11 so that the display screen 11 can display the video. Furthermore, parallel signals can be transmitted at high speed over short distances compared to serial signals. Therefore, the serial signal is deserialized by the deserializer 15 to obtain a parallel signal, thereby achieving high-speed transmission of the signal over short distances.

[0027] Furthermore, the first wire harness interface 12 is electrically connected to the controller 14 through the deserializer 15. The serial signal transmitted from the first wire harness interface 12 to the deserializer 15 is deserialized by the deserializer 15 and transmitted to the controller 14 so that the controller 14 can analyze and process the signal.

[0028] Continue to refer to Figure 2 Optionally, the vehicle infotainment drive module 20 also includes a serializer 24, through which the second wiring harness interface 22 is electrically connected to the vehicle infotainment processor 21; the serializer 24 is used to convert the signals transmitted by the vehicle infotainment processor 21 into serial signals, and the signals transmitted by the vehicle infotainment processor 21 include at least one of video signals and control signals.

[0029] For example, the signals transmitted by the vehicle infotainment processor 21 include video signals and control signals. Since serial signals require fewer lines to transmit than parallel signals, a serializer 24 is needed to convert the signals transmitted by the vehicle infotainment processor 21 into serial signals in order to reduce the number of lines for signal transmission. The serial signal is transmitted between the second wiring harness interface 22 and the first wiring harness interface 12.

[0030] Furthermore, the vehicle infotainment processor 21 can also detect whether the line between the first wiring harness interface 12 and the second wiring harness interface 22 is normal through the serializer 24. For example, after the vehicle infotainment processor 21 transmits a signal to the serializer 24, the serializer 24 converts the signal transmitted by the vehicle infotainment processor 21 into a serial signal and outputs it to the second wiring harness interface 22. If the line between the first wiring harness interface 12 and the second wiring harness interface 22 is normal, the serial signal can be transmitted to the deserializer 15 through the second wiring harness interface 22 and the first wiring harness interface 12 in sequence. When the deserializer 15 receives the serial signal, it can send a feedback signal to the serializer 24 to indicate that the serial signal has been received. The vehicle infotainment processor 21 can detect that the serializer 24 has received the feedback signal, thereby determining that the line between the first wiring harness interface 12 and the second wiring harness interface 22 is normal and that the communication between the first wiring harness interface 12 and the second wiring harness interface 22 is normal. If there is a line fault between the first wiring harness interface 12 and the second wiring harness interface 22, the deserializer 15 will not be able to receive the serial signal, nor will it be able to send a feedback signal to the serializer 24. At the same time, the serializer 24 will also not receive the feedback signal. The vehicle processor 21 detects that the serializer 24 has not received the feedback signal, thus determining that there is a line fault between the first wiring harness interface 12 and the second wiring harness interface 22. The communication between the first wiring harness interface 12 and the second wiring harness interface 22 is abnormal. At this time, the vehicle processor 21 can transmit a signal to the vehicle screen module 10 through the second wireless communication unit 23 to ensure that the vehicle processor 21 and the vehicle screen module 10 can communicate normally.

[0031] Optionally, the communication methods of the first wireless communication unit 13 and the second wireless communication unit 23 include at least one of WIFI, 4G, and 5G.

[0032] For example, the communication method of the first wireless communication unit 13 and the second wireless communication unit 23 is WIFI. WIFI communication is convenient, fast, and highly flexible. Not only can the first wireless communication unit 13 and the second wireless communication unit 23 communicate via WIFI, but electronic devices carried by passengers in the vehicle, such as laptops and mobile phones, can also access the WIFI network. It offers high transmission speeds: modern WIFI technology supports high data transmission speeds, meeting the bandwidth requirements of applications such as high-definition video playback, large file downloads, and online games. For example, WIFI networks using standards such as 802.11ac and 802.11ax (WIFI 6) can theoretically provide data transmission rates of hundreds of Mbps or even higher. It is easily expandable: when the WIFI network inside the vehicle needs to expand its coverage or increase its capacity, simply adding wireless access points or other devices can expand the WIFI network, meeting the connection needs of more users and devices. It has strong compatibility: almost all modern electronic devices support WIFI functionality, including smartphones, tablets, laptops, smartwatches, and smart home appliances, facilitating interconnection and data sharing between different devices and improving the user experience.

[0033] Optionally, the vehicle-mounted screen module further includes a first battery unit, which is electrically connected to the first wireless communication module and the display screen. The first battery unit supplies power to the first wireless communication module and the display screen, providing the necessary electrical energy for their normal operation.

[0034] Optionally, the display screen is detachable.

[0035] Specifically, the detachable display facilitates repair and replacement, reducing maintenance costs: When the display malfunctions, such as screen damage, backlight issues, or circuit failures, the detachable design allows for individual display replacement instead of replacing the entire device, thus saving on repair costs. Improved repair efficiency: Repair personnel can more quickly locate and resolve problems, directly removing and replacing the faulty display, reducing repair time and improving the usability of the vehicle display module. Portability: Users can detach the display and carry it in their hands or place it in a specific location, enhancing the user experience. Easy upgrades and expansion: As technology advances, users can choose to replace the display with a higher resolution, better display effect, or display with new functions according to their needs and budget, improving the overall performance and user experience of the vehicle display module; the detachable display also provides possibilities for functional expansion of the vehicle display module. For example, the detachable display can be used as an independent digital drawing board, connected to other devices to achieve specific functions, increasing the practicality and versatility of the vehicle display module. Extended lifespan: By replacing damaged or outdated displays, the vehicle display module can continue to be used, avoiding the need to discard the entire vehicle display module due to display problems, thus reducing electronic waste and being more environmentally friendly. Resource reuse: If the disassembled old display screen still has some use value, it can be recycled and reused, for example, to repair other similar equipment, or after processing, it can continue to play a role in situations where display requirements are not high, thus improving the utilization rate of resources.

[0036] Furthermore, detachable displays need to consider the following aspects: compatibility: ensuring compatibility between the display and the vehicle's drive module; display performance: higher resolution provides clearer and more detailed images, such as 4K (3840×2160) or 8K (7680×4320) resolution, which is suitable for professional graphic design, high-definition video playback, and high-end gaming scenarios; refresh rate: the refresh rate determines the speed at which the screen image is updated. High refresh rates, such as 144Hz or 240Hz, make dynamic images smoother, reduce ghosting and blurring, and improve the user experience; color performance: including indicators such as color gamut, color depth, and color accuracy. A wide color gamut allows the display to present richer colors, which is important for work that requires accurate color reproduction; the higher the color depth, the more natural the color transition and the more accurate the colors. Screen Size and Aspect Ratio: Choose a suitable size and aspect ratio based on the vehicle's interior space and user needs, such as 13-15 inches or larger. Common screen aspect ratios include 16:9, 16:10, 21:9, and 3:2. 16:9 is the most common ratio, suitable for watching movies and most games. 21:9 is suitable for multitasking and widescreen gaming, providing a wider field of view. 3:2 offers more content display space for reading and document processing. Portability: Choose a slim and lightweight display to reduce user weight when holding the screen, improving the user experience. Durability: Consider the display's material and structure, choosing a robust and durable product to prevent damage during disassembly, installation, or daily use. For example, displays using high-strength glass or with scratch- and drop-resistant designs are better suited to different environments. Disassembly Method: Choose a simple and quick disassembly method, such as a display with a magnetic, snap-on, or plug-in design. Avoid overly complicated disassembly processes to prevent damage or wasted time. Ensure that the disassembly process does not cause physical damage to the display.

[0037] Optionally, the vehicle infotainment system drive module also includes a second battery unit, which is electrically connected to the second wireless communication module and the vehicle infotainment processor. The second battery unit supplies power to the second wireless communication module and the vehicle infotainment processor, providing the necessary electrical energy for their normal operation.

[0038] Optionally, the connection between the first harness interface and the second harness interface is a high-speed signal twisted pair cable.

[0039] Specifically, high-speed signal twisted-pair cables are used to transmit high-speed signals. These cables consist of two insulated wires twisted together, each typically made of copper or other highly conductive metals. The twisting reduces electromagnetic interference and crosstalk, improving signal transmission quality and stability. High-speed signals transmitted over twisted-pair cables utilize the principle of differential signal transmission. Differential signal transmission uses two wires to transmit a pair of signals with opposite phases, reconstructing the original signal by comparing the voltage difference between the two wires. This transmission method effectively suppresses common-mode interference, improving signal immunity. High-speed signal twisted-pair cables possess the following characteristics: High bandwidth: They support high data transmission rates, meeting the demands of high-speed signal transmission. For example, some high-speed signal twisted-pair cables can support data transmission rates of 10Gbps or even higher. Low attenuation: During signal transmission, signal attenuation is minimal, ensuring high signal quality even after long-distance transmission. Strong anti-interference capability: Due to the use of differential signal transmission and the twisted-pair structure, they effectively resist external electromagnetic interference and crosstalk, improving the reliability of signal transmission. High-speed signal twisted-pair cables can be classified according to transmission rate into 100Mbps, 1Gbps, and 10Gbps twisted-pair cables, etc., with different types suitable for different data transmission rate requirements. They can also be classified according to insulation material into PVC insulated twisted-pair cables and low-smoke halogen-free insulated twisted-pair cables. The specific type of high-speed signal twisted-pair cable can be determined based on the actual needs of the vehicle display system and is not limited here.

[0040] Furthermore, high-speed signal twisted-pair cables need to be selected based on actual application requirements to support the corresponding transmission rate, ensuring rapid signal transmission. The bandwidth of the high-speed signal twisted-pair cable also needs to be selected based on actual application requirements to meet signal transmission demands; generally, higher bandwidth results in better signal transmission quality. Since signal transmission over twisted-pair cables experiences some attenuation, a suitable twisted-pair cable should be selected based on the actual transmission distance, typically used for signal transmission within 100 meters. Environmental requirements: Appropriate insulation materials and protective measures should be selected based on the operating environment. For example, in humid environments, waterproof twisted-pair cables should be selected; in flammable environments, flame-retardant twisted-pair cables should be selected. For high-speed signal twisted-pair cables connecting the first and second wiring harness interfaces in automotive display systems, waterproof and flame-retardant twisted-pair cables can be used, depending on the specific requirements of the automotive display system, and are not limited here.

[0041] In addition, before connecting the first and second harness interfaces of a high-speed signal twisted pair cable, it is necessary to confirm the specifications and model: select the appropriate specification of high-speed signal twisted pair cable, such as Category 5e, Category 6, or Category 7 twisted pair cable, based on the harness interfaces and transmission requirements, ensuring that it supports the required transmission rate and bandwidth. Cable quality: the outer sheath of the twisted pair cable needs to be checked for defects such as damage and scratches, and to ensure that the internal conductors have no open circuits or short circuits. A professional cable tester can be used for testing. When connecting the first and second harness interfaces of a high-speed signal twisted pair cable, interference must be avoided: the high-speed signal twisted pair cable should be kept away from power lines and other sources of interference as much as possible to reduce electromagnetic interference. If parallel laying cannot be avoided, a certain safe distance should be maintained, such as a distance of not less than 30cm. Attention should also be paid to the bending radius of the twisted pair cable to avoid excessive bending that could damage the internal structure of the cable. Generally, the bending radius of the twisted pair cable should not be less than four times its outer diameter. High-speed signal twisted pair cables can be fixed with cable clips or cable trays to prevent the cable from shaking or being pulled, ensuring the stability of the cable. Fix it at regular intervals, such as 1-2 meters. Connectivity Testing: A network cable tester can be used to test the connectivity of the installed high-speed signal twisted-pair cable to determine if each wire is properly connected and to check for short circuits, open circuits, or incorrect wiring sequences. If any problems are found, the cable should be replaced or repaired promptly to prevent the high-speed signal twisted-pair cable from failing to transmit signals correctly. Avoid Overloading: The data throughput of the high-speed signal twisted-pair cable should not exceed its rated transmission capacity to avoid signal distortion or transmission errors. Plan the data transmission volume reasonably according to the specifications of the high-speed signal twisted-pair cable and the performance of the vehicle display system. Regular Inspection and Maintenance: The connection status of the high-speed signal twisted-pair cable should be checked regularly. If any problems are found, the cable should be replaced or repaired promptly to ensure the stability of signal transmission.

[0042] The main types of high-speed twisted-pair cables include Category 5e, Category 6, Category 6A, Category 7, and Category 8. Category 5e twisted-pair cables support Ethernet transmission rates of up to 1000Mbps and have a bandwidth of up to 250MHz. Compared to Category 5, they utilize more advanced twisting technology and higher-quality insulation materials, significantly improving interference resistance and signal transmission stability. They can meet the data transmission needs of daily office work, such as file sharing, web browsing, and email. Category 6 twisted-pair cables support Ethernet transmission rates of up to 10Gbps and have a bandwidth of 550MHz. Structurally, Category 6 cables incorporate a cross-shaped frame, placing the four twisted pairs in four quadrants to further reduce crosstalk between pairs. They also use a higher-quality shielding layer, improving interference resistance. They are suitable for scenarios with high network bandwidth requirements, such as environments that need to support high-definition video playback and multiple devices simultaneously performing high-speed network applications. Category 6 A twisted-pair cable, an enhanced version of Category 6 cable, offers bandwidth up to 500MHz, doubling the transmission frequency of Category 6 cable. It employs more advanced shielding technology and materials, effectively resisting electromagnetic interference and exhibiting superior performance in 10Gbps Ethernet transmission, especially with less signal attenuation over long distances. It is primarily used for long-distance 10Gbps Ethernet transmission. Category 7 twisted-pair cable supports transmission rates up to 100Gbps with a bandwidth of 600MHz. It utilizes completely independent shielding layers; each twisted pair has its own shield before being shielded as a whole. This double-shielded structure provides excellent anti-interference performance, effectively preventing signal leakage and external interference, making it suitable for applications with extremely high network performance and security requirements. Category 8 twisted-pair cable boasts a bandwidth of up to 2000MHz and a transmission rate of up to 40Gbps. It also features extremely low transmission latency and excellent anti-interference performance. Typically, it employs more advanced materials and manufacturing processes to meet the requirements of ultra-high-speed network transmission. It can be applied to high-end networks that need to support ultra-high-speed Ethernet and can meet the future demand for ever-growing network bandwidth, providing a reliable connection for high-speed data transmission.

[0043] In addition, there are some special types of high-speed signal twisted-pair cables, such as industrial-grade twisted-pair cables for industrial environments, which have higher protection levels and anti-interference capabilities and are suitable for harsh industrial production environments; and outdoor twisted-pair cables for outdoor cabling, which have waterproof, sunproof, and corrosion-resistant properties and can be used for outdoor network construction.

[0044] It should be noted that the specific type of high-speed signal twisted pair cable used in this embodiment can be determined according to the actual needs of the vehicle display system, and is not limited here.
