Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display data transmission structure and display device. Background Technology

[0002] The display screen of current display devices is usually composed of multiple display cabinets spliced ​​together. In practical application scenarios, after multiple display cabinets are physically spliced ​​together, the debugging personnel need to manually observe the physical wiring connection sequence between the cabinets on the back of the display screen, identify the cable layout path and cascade topology by visual inspection, and on this basis, configure parameters such as position encoding and data partitioning for each display cabinet in the host computer software, so that the spliced ​​display screen can display a complete and unified image.

[0003] However, this method, which relies on manual observation and configuration, is prone to misjudgment of connection order due to complex cable layouts. At the same time, it cannot adapt to the needs of dynamic adjustment of display screen size or rapid replacement of faulty cabinets. The system's flexibility and maintainability are severely restricted, making it difficult to meet the requirements of intelligent deployment and real-time operation and maintenance of modern large-scale displays. Utility Model Content

[0004] The main purpose of this application is to provide a display data transmission structure and display device, which aims to solve the technical problem that conventional display screen composition schemes are difficult to meet the requirements of intelligent deployment and real-time operation and maintenance of modern large-scale display screens.

[0005] To achieve the above objectives, this application proposes a display data transmission structure, which is applied to a display device and includes a processing unit and a plurality of display data transmission units.

[0006] Each display data transmission unit is connected in series to establish a communication connection, which is used to transmit the connection position information generated according to the communication connection to the previous display data transmission unit in the series.

[0007] The processing unit establishes a communication connection with the first display data transmission unit, which is the first in the serial sequence, to determine the connection order between the display data transmission units based on the connection position information of each display data transmission unit transmitted by the first display data transmission unit.

[0008] In one embodiment, all display data transmission units have the same structure, and the display data transmission unit is a four-sided ring structure.

[0009] In one embodiment, a millimeter-wave wireless Ethernet module is provided on each of the four sides of the display data transmission unit.

[0010] In one embodiment, a receiving card is provided at the center point of the display data transmission unit;

[0011] The receiver card establishes a connection with each millimeter-wave wireless Ethernet module.

[0012] In one embodiment, up to two millimeter-wave wireless Ethernet modules in the display data transmission unit establish communication connections with millimeter-wave wireless Ethernet modules in adjacent display data transmission units.

[0013] In one embodiment, the millimeter-wave wireless Ethernet module is used to: generate a physical link status signal and transmit the physical link status signal to the receiving card when establishing a communication connection with a millimeter-wave wireless Ethernet module in an adjacent display data transmission unit.

[0014] In one embodiment, the receiving card is configured to: generate connection location information from the accessed physical link status signal.

[0015] In one embodiment, the processing unit includes a sending card, which establishes a communication connection with the first display data transmission unit;

[0016] The sending card is used to determine the connection location information corresponding to each connected display data transmission unit.

[0017] In one embodiment, the processing unit further includes a host computer, which establishes a connection with the sending card;

[0020] One or more technical solutions proposed in this application have at least the following technical effects:

[0021] A display data transmission structure is proposed, which includes a processing unit and several display data transmission units. Each display data transmission unit is connected in series to establish a communication connection, which is used to transmit the connection position information generated according to the communication connection to the preceding display data transmission unit in the series. The processing unit establishes a communication connection with the first display data transmission unit in the series sequence, which is used to determine the connection order between each display data transmission unit according to the connection position information of each display data transmission unit passed in by the first display data transmission unit.

[0022] In this application, by modifying the internal structure of the display cabinet, i.e. the display data transmission unit, it is made possible to generate connection position information based on the communication connection relationship with other display data transmission units. Based on the serial relationship between each display data transmission unit, the connection position information is transmitted to the processing unit. The processing unit can quickly and accurately determine the connection order between each display data transmission unit without manual operation. This avoids the setting errors that may occur with manual operation, and can meet the needs of dynamic adjustment and rapid replacement, effectively meeting the requirements of intelligent deployment and real-time operation and maintenance of large-scale displays.

[0035] Based on this, embodiments of this application provide a display data transmission structure, referring to... Figure 1 , Figure 1 This is a schematic diagram of the data transmission structure shown in this application.

[0036] This display data transmission structure is applied to a display device. The display data transmission structure includes a processing unit 10 and several display data transmission units 20. Each display data transmission unit 20 is connected in series to establish a communication connection, used to transmit connection location information generated according to the communication connection to the preceding display data transmission unit 20 in the series connection. The processing unit 10 and the first display data transmission unit (i.e., the first one in the series sequence) are connected in series. Figure 3 The 20(1)) establishes a communication connection, which is used to determine the connection order between each display data transmission unit 20 based on the connection position information of each display data transmission unit 20 transmitted by the first display data transmission unit.

[0037] In conventional display data transmission structures, the corresponding display screen consists of multiple display cabinets. The image that the display screen can show is determined by the display cabinets. Therefore, after splicing the display cabinets together, it is necessary to determine the splicing order between them so that the images sent to each display cabinet can be combined to form the target image. Determining the splicing order is therefore crucial. However, as described in the background section, the conventional method for determining the splicing order requires manual configuration by debugging personnel after observation, which cannot meet the needs of intelligent deployment and real-time operation and maintenance of large-scale displays.

[0038] Therefore, based on the aforementioned problems, this embodiment proposes the following... Figure 1 The above describes a display data transmission structure. It should be noted that the display data transmission unit 20 in this embodiment is the display cabinet. This embodiment is an improvement on the structure of a conventional display cabinet, as shown below.

[0039] In this embodiment, each display data transmission unit 20 can generate corresponding connection position information based on its communication connection with other display data transmission units 20, and transmit the connection position information to the previous display data transmission unit 20 until the transmitting display data transmission unit 20 is the first in the serial sequence, that is, the first display data transmission unit. The first display data transmission unit transmits its generated connection position information and the connection position information of other display data transmission units 20 to the processing unit 10. Through the processing unit 10, the connection order between each display data transmission unit 20 is automatically determined, which avoids the setting errors that exist in manual operation, and can meet the needs of dynamic adjustment and rapid replacement, effectively meeting the requirements of intelligent deployment and real-time operation and maintenance of large display screens.

[0040] Specifically, the display data transmission structure proposed in this embodiment can be referred to Figure 2 As shown, each display data transmission unit 20 has the same structure, and the display data transmission unit 20 has a four-sided ring structure.

[0041] according to Figure 2 It can be seen that a millimeter-wave wireless Ethernet module 201 is provided on each of the four sides of the display data transmission unit 20.

[0042] A receiving card 202 is provided at the center point of the display data transmission unit 20; the receiving card 202 establishes a connection relationship with each millimeter-wave wireless Ethernet module 201.

[0043] Depend on Figure 2It is known that each of the four sides of the display data transmission unit 20 is provided with a millimeter-wave wireless Ethernet module 201. The purpose is that when the display data transmission unit 20 needs to be dynamically adjusted according to actual application requirements, the position of the display data transmission unit 20 can be changed directly without regard to the internal structure of the display data transmission unit 20. This allows the display data transmission unit 20 to establish a communication connection with the display data transmission units 20 that are connected in series, regardless of its position, through the millimeter-wave wireless Ethernet module 201 on the corresponding surface.

[0044] The receiver card 202 is located at the center of the display data transmission unit 20. Through the four I / O (Input / Output) interfaces on the receiver card 20, it establishes a connection with the four millimeter-wave wireless Ethernet modules 201 respectively. Through physical location optimization, it achieves a comprehensive improvement in signal transmission, synchronous control and system scalability, thereby supporting the efficient deployment and intelligent networking of large displays.

[0045] In current display data transmission structures, the receiver card 202 is typically located at the edge of the display cabinet and connected in series with adjacent display cabinets via cables. This layout easily leads to problems such as uneven signal transmission distance, cascade delay accumulation, and amplified synchronization errors. In this embodiment, the receiver card 202 is placed at the geometric center of the display data transmission unit 20. Firstly, from the perspective of signal transmission efficiency, the central position can balance the communication distance of the millimeter-wave wireless Ethernet modules 201 on the four sides of the cabinet, ensuring consistent signal loss between the modules in each direction and the receiver card 202, avoiding transmission delay differences caused by positional offsets. At the same time, the symmetrical layout can effectively suppress the impact of external electromagnetic interference on the core data processing module. Secondly, at the synchronization control level, the receiver card 202 serves as the central hub for analyzing video data and clock signals. The central positioning minimizes the physical distance between it and each display driving circuit. By using a unified clock reference, timing deviations caused by differences in signal propagation paths are eliminated, ensuring strict alignment of the full-screen refresh rate and horizontal and vertical synchronization signals.

[0046] according to Figure 3 It can be seen that at most two millimeter-wave wireless Ethernet modules 201 in the display data transmission unit 20 establish communication connections with the millimeter-wave wireless Ethernet modules 201 in the adjacent display data transmission unit 20.

[0047] The millimeter-wave wireless Ethernet module 201 is used to generate a physical link status signal and transmit the physical link status signal to the receiving card 202 when establishing a communication connection with the millimeter-wave wireless Ethernet module 201 in the adjacent display data transmission unit 20.

[0048] Receiver 202 is used to generate connection location information from the accessed physical link status signal.

[0049] Reference Figure 3 It is known that the processing unit 10 includes a sending card 101, which establishes a communication connection with the first display data transmission unit; the sending card 101 is used to determine the connection location information corresponding to each of the connected display data transmission units 20.

[0050] The processing unit 10 also includes a host computer 102, which establishes a connection with the sending card 101; the host computer 102 is used to determine the connection order between each display data transmission unit 20 according to the accessed connection location information.

[0051] In practical applications, after arranging each display data transmission unit 20 in sequence, Figure 3 For example, in the arrangement matrix of display data transmission units 20, starting from the first display data transmission unit, and following an S-shaped serial path, after establishing communication connections between the millimeter-wave wireless Ethernet modules 201 in each display data transmission unit 20, the millimeter-wave wireless Ethernet module 201 with established communication connections will send a physical link status signal, i.e., an Ethernet LED signal (i.e., ...) to its corresponding receiver card 202. Figure 2 (203) It should be noted that the receiving card 202 and the corresponding four millimeter-wave wireless Ethernet modules 201 are all marked with corresponding location information. For example, the location information corresponding to the receiving card 202 in the first display data transmission unit is 01, and the location information corresponding to the four millimeter-wave wireless Ethernet modules 201 are 000, 001, 100 and 110 respectively. When the millimeter-wave wireless Ethernet modules 201 with location information of 110 and 001 send a physical link status signal to the receiving card 202, the receiving card 202 can obtain the location information of 110 and 001, and after integrating the two location information, it generates the connection location information [01 001 110] together with its own location information and sends it to the sending card 101, until the connection location information sent by all display data transmission units 20 is received. The host computer 102 processes the connection location information to obtain the connection order between each display data transmission unit 20. Figure 3 The corresponding connection structure and the connection location information sent to the host computer 102 are [01 001 110] (corresponding to...) Figure 3 The first display data transmission unit (1) in the middle), [02 001 110] (corresponding to Figure 3 The display data transmission unit 20(2) in the middle), [03 001100] (corresponding to Figure 3 The display data transmission unit 20(3) in the middle), [04 000001] (corresponding to Figure 3 The display data transmission unit 20(4) in the middle), [05 001 110] (corresponding to Figure 3The display data transmission unit 20(5) in the middle), [06 110 100] (corresponding to Figure 3 The display data transmission unit 20(6) in the middle), [07 000 110] (corresponding to Figure 3 The display data transmission unit 20(7) in the middle), [08 001 110] (corresponding to Figure 3 The display data transmission unit 20(8) in the middle),

[09001] (corresponding to Figure 3 The display data transmission unit 20(9) is used in the display data transmission unit 20. Since the position information of the millimeter-wave wireless Ethernet module 201 in the same position in each display data transmission unit 20 is the same, the host computer 102 can automatically identify the splicing relationship between each display data transmission unit 20 according to the connection position information uploaded by each display data transmission unit 20, and realize the intelligent networking configuration of the large display screen.

[0052] in, Figure 2 Ethernet signals in (i.e.) Figure 2 204 in the figure represents the display data. The host computer 102 transmits the display data to be displayed by each display data transmission unit 20 according to the determined connection order between each display data transmission unit 20 through the sending card 101 and the connection order between each display data transmission unit 20. The receiving card 202 obtains the display data corresponding to the location information included in the received display data, and sends the display data with non-corresponding location information to the next display data transmission unit 20 through the millimeter-wave wireless Ethernet module 201.

[0054] Each display data transmission unit is connected in series to establish a communication connection, which is used to transmit the connection position information generated according to the communication connection to the previous display data transmission unit in the series.
