[0035] Considering that the existing dual-screen design is that the system on chip (SoC) obtains images from two independent storage spaces 0 or storage space 1, and displays the content on the independent display screen 0 or display screen 1 through the corresponding independent display interface 0 or display interface 1. The linkage process is that the SOC obtains data from storage space 0, sends it to storage space 1, and changes the image data of storage space 1; the SOC obtains data from storage space 1, sends it to storage space 0, and changes the image data of storage space 0. In this way, the image linkage effect on display screens 0 and 1 is achieved. This approach is very complex to implement in software, and there is a delay problem in the transportation of image data, resulting in a poor experience.

[0036] An embodiment of the present application provides a multi-screen linkage device comprising: a storage device, an image transmission device, a bridge chip, and a screen group comprising multiple display screens; the output of the storage device is connected to the input of the image transmission device; the output of the image transmission device is connected to the input of the bridge chip; and the output of the bridge chip is connected to each display screen in the screen group, so that each image stored in the storage device can be displayed across the multiple display screens. This advantageously reduces the delay in displaying images on multiple screens, thereby improving the user's viewing experience.

[0037] See also Figure 1 , Figure 1 One of the structural diagrams of a multi-screen linkage device 10 provided in this embodiment:

[0038] like Figure 1 As shown in , a multi-screen linkage device 10 provided in this embodiment includes: a storage device 11 , an image transmission device 12 , a bridge chip 13 , and a screen group 14 including at least two display screens 141 .

[0039] Specifically, the output end of the storage device 11 is connected to the input end of the image transmission device 12; the output end of the image transmission device 12 is connected to the input end of the bridge chip 13; the output end of the bridge chip 13 is connected to each display screen 141 in the screen group 14, so that each picture stored in the storage device 11 can be displayed through multiple display screens 141.

[0040] In a specific implementation, the image transmission device 12 receives the image data in the storage device 11 and transmits the image data to the bridge chip 13. The bridge chip 13 splits the same image into sub-images corresponding to the number of display screens, and sends each sub-image to a display screen 141 for display.

[0041] Here, the storage device 11 is used to store images that need to be displayed to the user. During the image display process, the image is transmitted to the image transmission device 12, which processes each frame of the transmitted image or video stream in real time, and the bridge chip 13 splits the image and outputs each split part to a display screen 141 for display.

[0042] In this way, the single image is split into multiple parts corresponding to the number of display screens through the bridge chip 13, and sent to the corresponding display screens 141 respectively, which can solve the current delay problem of multi-screen linkage and improve user experience.

[0043] Preferably, the display screen 141 is a vehicle-mounted display screen.

[0044] Preferably, the bridge chip 13 is an EDP to LVDS conversion chip, which converts the EDP signal into two LVDS (low voltage differential signal) outputs.

[0045] Optionally, the bridge chip 13 may also include one of an ANX7625 chip, a PS8640 chip, and a PS176HDM chip.

[0046] Here, the ANX7625 chip supports DisplayPort 1.3 input and MIPI DSI output. It can be used to convert and split the DisplayPort signal into two MIPI DSI signals, which are connected to two display screens 141. The PS8640 chip supports DisplayPort 1.2 input and MIPI DSI output. This chip can process high-resolution DisplayPort signals and convert them into MIPI DSI signals for display screen 141. The PS176HDM chip is mainly used for DisplayPort to HDMI conversion and is suitable for scenarios requiring HDMI output.

[0047] The bridge chip 13 is used to connect to the various interfaces or buses within the multi-screen linkage device 10, acting as a "bridge" between the image transmission device 12 and the display screen 141 within the multi-screen linkage device 10, facilitating data and signal transmission. It is responsible for converting the image data output by the image transmission device 12 into a format acceptable to the display screen 141. For example, it converts EDP signals into two LVDS (low-voltage differential signal) outputs to drive different types of display panels. It can also perform processing tasks such as image segmentation and scaling, particularly within the multi-screen linkage device 10, dividing a single image into multiple parts for display on different display screens 141.

[0048] An embodiment of the present application provides a multi-screen linkage device comprising: a storage device, an image transmission device, a bridge chip, and a screen group comprising multiple display screens; the output of the storage device is connected to the input of the image transmission device; the output of the image transmission device is connected to the input of the bridge chip; and the output of the bridge chip is connected to each display screen in the screen group, so that each image stored in the storage device is split across multiple display screens for display. This advantageously reduces the delay in displaying images on multiple screens, thereby improving the user's viewing experience.

This can reduce system size and power consumption, while improving performance and efficiency. This integrated design is widely used in automotive electronic systems.

[0053] The system-level chip 121 may be a Qualcomm 8155 or Qualcomm 8295 chip.

[0054] In a specific implementation, the system-level chip 121 processes and transmits each frame of the image or video stream sent by the storage device 11 in real time, and transmits it to the bridge chip 13 through the interface device 122 .

[0055] In a possible embodiment, the interface device is preferably an image display interface, and the image display interface includes at least one of a MIPI DSI interface, an HDMI interface, and a DP / EDP interface.

[0056] The MIPI DSI (Display Serial Interface) is suitable for high-resolution, low-power in-vehicle displays. Its advantages include low power consumption, low EMI (electromagnetic interference), high bandwidth, support for high refresh rates, and deep color depth. It is compatible with the Parade PS8640 (DisplayPort to MIPI DSI converter) and Analogix ANX7625 (DisplayPort to MIPI DSI converter) chips. The HDMI (High-Definition Multimedia Interface) interface supports audio and video signal transmission, high bandwidth, and supports multiple resolutions and refresh rates. It is compatible with the Silicon Image SiI9022A (HDMI transmitter) and NXP TDA19988 (HDMI transmitter) chips.

[0057] It should be noted that the selection of the display interface should be based on the following key factors: Type and specifications of the display: including resolution, refresh rate, interface type (such as MIPI DSI, LVDS, HDMI, eDP, etc.). Bandwidth requirements for image data: Displays with high resolution or high refresh rate require higher bandwidth. Power consumption and electrical characteristics: In some applications, such as mobile devices or in-vehicle systems, low power consumption and low interference characteristics are very important. System integration and compatibility: The display interface needs to be compatible with the system-level chip 121 in the multi-screen linkage device 10.

Its beneficial effect is to reduce the delay problem of displaying images on multiple screens and improve the user's viewing experience.

[0060] like Figure 3 As shown in , a multi-screen linkage device 10 provided in this embodiment includes: a storage device 11, an image transmission device 12, a bridge chip 13, and a screen group 14 including multiple display screens 141. The image transmission device 12 includes a system-on-chip 121 and an interface device 122. The system-on-chip 121 includes an image processing pipeline 1211.

[0061] Specifically, the output of storage device 11 is connected to the input of image transmission device 12; the output of image transmission device 12 is connected to the input of bridge chip 13; the output of bridge chip 13 is connected to each display screen 141 in screen group 14, so that each image stored in storage device 11 can be displayed on multiple display screens 141. The input of system-on-chip 121 is connected to the output of storage device 11; the output of system-on-chip 121 is connected to the input of bridge chip 13 via interface device 122. The input of image processing pipeline 1211 is connected to the output of storage device 11; the output of image processing pipeline 1211 is connected to interface device 122.

[0062] Here, image processing pipeline 1211 is used to perform real-time image processing on each frame. This can be implemented using a commonly used image processor or image processing chip, such as the ARM Mali-C71 chip, which is suitable for in-vehicle and surveillance systems and supports high dynamic range (HDR), wide color gamut, and noise reduction.

The Texas Instruments TDA4VM chip is designed specifically for autonomous driving and ADAS (advanced driver assistance systems), supporting advanced image processing, machine learning, and perception algorithms. It integrates an image signal processor (ISP) and video codec, supporting multiple video inputs and outputs.

[0063] For further information, see Figure 4 , Figure 4 This is a fourth structural diagram of a multi-screen linkage device 10 provided in an embodiment of the present utility model.

[0064] like Figure 4 As shown in FIG, a multi-screen linkage device 10 provided in this embodiment includes a storage device 11, an image transmission device 12, a bridge chip 13, and a screen group 14. The image transmission device 12 includes a system-on-chip 121 and an interface device 122. The system-on-chip 121 includes an image processing pipeline 1211. The screen group 14 includes a first display screen 41 and a second display screen 42.

[0065] Specifically, the output of storage device 11 is connected to the input of image transmission device 12; the output of image transmission device 12 is connected to the input of bridge chip 13; the output of bridge chip 13 is connected to first display screen 41 and second display screen 42, respectively, so that each image stored in storage device 11 can be displayed on first display screen 41 and second display screen 42. The input of system-on-chip 121 is connected to the output of storage device 11; the output of system-on-chip 121 is connected to the input of bridge chip 13 via interface device 122. The input of image processing pipeline 1211 is connected to the output of storage device 11; the output of image processing pipeline 1211 is connected to interface device 122.

[0066] In practice, only one image is required, and the system-on-chip 121 can operate the first and second display screens 41, 42 as if they were a single display screen. The image is split into a left image and a right image within the bridge chip 13, which are displayed on the first and second display screens 41, 42, respectively. This approach reduces latency issues.

[0067] Among them, the first display screen 41 and the second display screen 42 can be display screens located on the left and right sides of the car's center console, and can be the same display screen or different display screens, and no specific limitation is made here.

[0068] Here, the system-on-chip 121 receives image data from the storage device 11 and transmits this data to the image processing pipeline 1211. After processing each image frame in real time, the image processing pipeline 1211 sends the data to the bridge chip 13 via the interface device 122. The bridge chip 13 splits the single image into left and right images, which are then transmitted to the first display screen 41 and the second display screen 42 via corresponding interfaces for display. This approach not only simplifies system design but also improves response speed and user experience.
