Description

TECHNICAL FIELD

[0002] The existing LED display screen system usually needs to be installed by a person according to a specific order, and the position information and resolution parameters of each box are manually configured. Once the installation order of the box is wrong or the parameter configuration is improper, the display content will be misaligned, the image will be incomplete, and the like, which seriously affects the display effect. In addition, when the display screen is large, the difficulty and workload of manual debugging increase greatly, which greatly reduces the installation and debugging efficiency.

If the image content or layout needs to be adjusted, complex settings and debugging must be performed again. Such an inefficient preview and change mechanism not only increases the operation difficulty, but also may cause the project progress to be delayed, thereby increasing the cost. SUMMARY

[0058] Figure 1 The method flowchart provided by the embodiment of the present application. DETAILED DESCRIPTION

[0059] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined invention purpose, the specific implementation, structure, features and effects of the LED display screen intelligent screen connection method according to the present application are described in detail as follows. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures or characteristics in one or more embodiments can be combined in any suitable form.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs.

[0061] The following embodiments are for illustrative purposes only, and are not intended to limit the scope of the present application.

[0062] The specific scheme of the LED display screen intelligent screen connection method provided by the present application is described in detail below with reference to the accompanying drawings.

[0063] Referring to Figure 1 , which shows a method flowchart of an LED display screen intelligent connection method provided by an embodiment of the present application, the method comprises the following steps:

[0064] Step S1, installing an LED box and collecting its position information;

[0065] In step S1, the following sub-steps are further included:

[0066] S1-1, installing an LED box, the LED box being internally provided with a wireless communication module, a gyroscope and an acceleration sensor;

[0067] S1-2, the LED box collecting LED box position information through the gyroscope and the acceleration sensor;

[0068] S1-3, the LED box performing wireless signal connection with a central control system through the wireless communication module.

[0069] It should be noted that the central control system is the core of data processing and instruction transmission, mainly responsible for data collection and management, connection topology identification, image processing and distribution, fault tolerance and self-adaptation, real-time synchronous control and other functions, and plays a core role in coordination, management and control in the LED display screen intelligent connection method, ensuring efficient operation of the entire system and optimization of display effect.

[0070] The wireless communication module provides efficient, flexible and reliable communication support for the LED display screen intelligent connection system, and is one of the core components for realizing system intelligence and automation. Through the wireless communication module, the central control system can dynamically update the box information database, ensuring that the system can reflect the installation order and position changes of the box in real time, so that the system can adapt to any installation order and dynamically adjust the display content. At the same time, the use of the wireless communication module reduces the need for wiring, and there is no need to rewire when adding or replacing boxes, effectively improving the flexibility and expandability of the system.

[0071] Step S2, obtaining resolution parameters of each LED box, and generating a box information database in combination with the position information and the resolution parameters;

[0072] In step S2, the following sub-steps are further included:

[0073] S2-1, the central control system receiving the position information of the LED box through the wireless communication module, and obtaining resolution parameters of each LED box;

[0074] S2-2, the central control system assigning a unique position code to each LED box according to the position information, and identifying the position of each LED box in the splicing array through the position code;

[0075] S2-3, establish a cabinet information database, associate the position code of each LED cabinet with the resolution parameter, establish a mapping relationship between the position and the resolution and store it in the cabinet information database.

[0076] It should be noted that the resolution parameter of the LED cabinet is an important indicator for measuring the display definition and image quality. The resolution is usually expressed in horizontal pixel number x vertical pixel number. These parameters directly determine the degree of image detail and the size of the picture that the cabinet can display.

[0077] Method for assigning position code:

[0078] Through sensors (such as gyroscopes, acceleration sensors) and wireless signal strength triangulation algorithm, the physical position information of each LED cabinet in the splicing array is obtained. The (x, y) coordinates are used in combination with the row and column numbers to represent the position of the cabinet. For example, A1(0, 0) represents the first row and first column cabinet, and B2(1, 1) represents the second row and second column cabinet.

[0079] The cabinet information database can be in table form, with each row recording the information of a cabinet, including position code and resolution parameter. For example:

[0080] Position code | Resolution parameter

[0081] ---------|------------

[0082] A1 | 1920x1080

[0083] A2 | 1280x720

[0084] B1 | 1920x1080

[0085] B2 | 1280x720

[0086] Step S3, dynamically generate cabinet connection topology graph according to cabinet information database;

[0087] In step S3, the following sub-steps are also included:

[0088] S3-1, the central control system analyzes the relative position between LED cabinets through position code to obtain cabinet position relationship information;

[0089] S3-2, the central control system identifies the connection relationship of adjacent LED cabinets through the wireless communication module to obtain cabinet connection state information;

[0090] S3-3, generate cabinet connection topology graph according to position relationship information and connection relationship information.

[0091] It should be noted that the box connection relationship information refers to the specific situation of physical connection between each LED box in the LED display screen connection system, which describes the connection state of each box and adjacent box, including the connection direction (such as up, down, left and right) and the connection order, for example: box A1 is connected to A2 (right side) and B1 (lower side), A2 is connected to A1 (left side) and B2 (lower side), etc. The connection relationship information is the basis for generating the box connection topology graph, which is used for dynamically adjusting the display content distribution, ensuring seamless splicing of images between different boxes, and supporting arbitrary installation order and flexible splicing mode.

[0092] The box connection topology graph intuitively shows the splicing structure and connection relationship of the box, which is convenient for technicians to quickly understand the overall layout of the system, quickly locate the fault box or connection abnormality, and improve the maintenance efficiency. In addition, the box connection topology graph can reflect the changes of the installation order and connection state of the box in real time, support arbitrary installation order and multi-resolution box mixed splicing, and correctly display even when the box is not installed according to the predetermined order.

[0093] Step S4, calculating and generating display data, image partition information and refresh timing control parameters according to the box information database through an adaptive resolution matching algorithm;

[0094] In step S4, the following sub-steps are further included:

[0095] S4-1, constructing a virtual display coordinate system according to the box information database and the box connection topology graph;

[0096] S4-2, converting the display image from the original coordinate system to the virtual display coordinate system through an affine transformation algorithm, and further mapping to the display buffer of each LED box;

[0097] S4-3, generating image partition information according to the result of affine transformation, calculating the display content of each LED box and the pixel-level offset compensation value of the display content;

[0098] S4-4, calculating the scaling factor according to the resolution and display area size of the LED box;

[0099] S4-5, generating refresh timing control parameters for each LED box according to the system refresh rate requirement.

[0100] It should be noted that the virtual display coordinate system usually takes the upper left corner of the entire LED display screen as the origin, the horizontal direction as the horizontal axis, and the vertical direction as the vertical axis. The central control system determines the position and size of each box in the virtual display coordinate system according to the physical position information and resolution parameters in the box information database. The purpose of constructing the virtual display coordinate system is to create a unified coordinate reference frame for the entire LED display screen, so as to accurately map the input image to each box.

[0101] Affine transformation is a linear transformation that can realize translation, rotation, scaling and shearing operations. Affine transformation can be represented by a 2x3 transformation matrix:

[0102]

[0103] Where x and y are the horizontal and vertical coordinates of the original coordinates in the input image, x' and y' are the horizontal and vertical coordinates of the transformed image coordinates, a, b, c, d, e, f are all parameters in the matrix, and the parameters in the matrix determine the specific way of transformation, including:

[0104] Translation: According to the position of the box in the virtual display coordinate system, calculate the translation parameters c and f, and move the image to the correct position;

[0105] Scaling: According to the resolution parameters of the box, calculate the scaling parameters a and e, and adjust the size of the image to adapt to the display area of the box;

[0106] Rotation (optional): If necessary, you can adjust the direction of the image by rotating parameters b and d.

[0107] Pixel-level offset compensation value is a key parameter in the intelligent screen connection system of LED display screen, which is used to ensure the accurate alignment of the image when multiple boxes are spliced. By applying the pixel-level offset compensation value, the system can accurately adjust the image content to the display area of each box, realizing seamless splicing;

[0108] Scaling factor refers to the scaling degree of the image in the horizontal and vertical directions. The scaling factor determines the size of the image in the box display buffer;

[0109] Refresh timing control parameter is used to ensure that all boxes can update the display content synchronously, avoiding display tearing or flickering.

[0110] Step S5, realizing preview and change of the display image through visual method;

[0111] In step S5, the following sub-steps are also included:

[0112] S5-1, a display preview interface is established, and a virtual display coordinate system is displayed as a grid, where each node represents an LED box, and the connection between nodes represents the physical connection relationship between LED boxes;

[0113] S5-2, the assigned display content is previewed with the virtual display coordinate system to check the overall display effect;

[0114] S5-3, the display image parameters can be changed by the staff through the display preview interface, including image length and width, image rotation angle, image resolution, image brightness, and image contrast.

[0115] It should be noted that the visualization method is a technical means for optimizing the management of LED display screen content. In the scenario of multi-box splicing of LED display screens, the visualization method allows users to preview the rendering effect of images on the spliced screen through a software interface before actual display. Users can adjust the layout, size, and position of images during the preview stage to ensure that the final display effect meets expectations.

[0116] The specific implementation is as follows:

[0117] Preview function: The system provides a virtual display screen interface that simulates the layout and size of the actual LED display screen. Users can import the image to be displayed into the interface to intuitively view the display effect of the image on the spliced screen;

[0118] Adjustment function: Users can adjust the position and size of the image through operations such as dragging and zooming. The system updates the preview effect in real time, allowing users to immediately see the adjusted results;

[0119] Parameter setting: Users can set display parameters such as resolution, brightness, and contrast. The adjustment of these parameters can also be reflected in real time during preview;

[0120] Immediate feedback: Through visual preview, users can immediately discover and correct issues in image display, such as image cropping and misalignment, avoiding errors in actual display.

[0121] This visualization method greatly improves the efficiency and accuracy of display content management, especially for large LED display screens or complex splicing scenarios, significantly reducing on-site debugging time and cost.

[0122] Step S6, the central control system generates display control instructions based on the display data and image partition information, and controls the refresh rate of each LED box based on the refresh timing control parameters;

[0123] In step S6, the following sub-steps are included:

[0124] S6-1, the central control system generates display control instructions according to display data and image partition information, the display data including display content, pixel-level offset compensation value and scaling factor;

[0125] S6-2, the central control system synchronizes the refresh rate of each LED box according to the refresh timing control parameter;

[0126] S6-3, the central control system synchronizes the display content of each LED box through frame synchronization technology.

[0127] It should be noted that the main role of frame synchronization technology is to ensure that all LED boxes update the display content at the same time, avoid display tearing, flickering or misplacement caused by refresh rate difference or data transmission delay, and thus realize seamless image splicing and high-quality visual effect.

[0128] The specific implementation is as follows:

[0129] Synchronization signal generation: the central control system generates a global synchronization signal, which contains frame synchronization pulses and line synchronization pulses, the frame synchronization pulses are used to mark the beginning of each frame, and the line synchronization pulses are used to mark the beginning of each line.

[0130] Signal distribution: the central control system sends the synchronization signal to each LED box through high-speed communication links (such as LVDS, HDMI, DP), these communication links have low delay and high bandwidth characteristics, which can ensure real-time transmission of the synchronization signal.

[0131] Box receiving and processing: after each LED box receives the synchronization signal, it adjusts its display timing according to the frame synchronization pulses and line synchronization pulses. The display driving circuit inside the box accurately controls the refresh time of the pixels according to the synchronization signal, ensuring that all boxes update the display content at the same time.

[0132] Step S7, verify data integrity through a redundancy checking mechanism;

[0133] In step S7, the following sub-steps are also included:

[0134] S7-1, the central control system performs redundancy checking calculation on the display control instructions, generates a central check code, packs the display control instructions and the check code into a data packet, and sends the data packet to each LED box through the wireless communication module;

[0135] S7-2, the LED box receives the data packet, performs redundancy checking calculation on the display control instructions, and generates a box check code;

[0136] S7-3, compare the central check code with the box check code:

[0137] If the check code is consistent, it is judged that the data is complete, and the LED box executes the display control instruction.

[0138] If the check code is inconsistent, it is judged that the data is abnormal, the LED box sends a request for retransmission instruction to the central control system, returns to step S6, and generates a display control instruction again.

[0139] It should be noted that the redundancy check mechanism is a technical means for verifying data integrity and accuracy by adding extra data, which provides a self-verification and error correction capability for data. It not only can detect whether the data is damaged, but also can automatically correct errors in some cases, so as to ensure the integrity of the data and the stability of the system. Therefore, the redundancy check mechanism is a necessary means to ensure the reliability of data transmission and storage, and is widely used in communication, storage, network and other fields.

[0140] Step S8, each LED box displays image content according to the display control instruction;

[0141] In step S8, the following sub-steps are further included:

[0142] S8-1, the LED box receives the display control instruction of the central control system, and the display control instruction includes:

[0143] Display the image according to the display content;

[0144] Adjust the pixel offset of the display content according to the pixel-level offset compensation value;

[0145] Adjust the scaling ratio of the display content according to the scaling factor, and align the display boundaries of different resolution LED boxes;

[0146] S8-2, each LED box executes the display control instruction to realize cooperative display of image content.

[0147] It should be noted that the display boundary of the LED box refers to the physical boundary of the display area of each LED box in the LED display screen splicing system. These boundaries define the specific range of image content that each box can display, which is a key factor to ensure seamless alignment and avoid overlapping or missing when splicing images.

[0148] By precisely defining the display boundary of each box, the system can ensure that the images are aligned when spliced, avoiding image misalignment or overlapping caused by inconsistent boundaries. In the multi-box splicing scenario, the display boundary helps the system to realize seamless splicing, making the entire display screen look like a complete display unit.
