Abstract
Description
Technical Field
[0001] This invention belongs to the field of LED display technology, and in particular to an LED control card and display device that integrates power supply and control functions. Background Technology
[0002] The installation and deployment of traditional LED displays requires separate power supply boxes, control cards, and a large number of connecting cables. This not only leads to complex wiring and cumbersome installation procedures, severely affecting installation efficiency, but also easily causes signal interference due to the coordinated operation of multiple components, affecting the display effect.
[0003] In existing technologies, some solutions attempt to optimize space occupancy through a split design, but there are still many drawbacks: First, the power supply and control unit are separated, requiring an additional independent power supply, which increases the overall size of the equipment and raises production costs; Second, when assembling the display screen, manual positioning and calibration of each module is required, which is cumbersome and inefficient, and prone to positioning errors; Third, the interfaces between modules are numerous and redundant, making it difficult to disassemble and replace parts during subsequent maintenance, resulting in high maintenance costs.
[0004] Therefore, there is an urgent need for a technical solution that can integrate power supply and control functions, simplify the installation process, and reduce costs and maintenance difficulties to meet the application requirements of rapid deployment of LED displays. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an LED control card and display device that integrates power supply and control functions. The technical problem to be solved by this invention is to solve the problems of complex wiring, low installation efficiency, high cost and difficult maintenance of traditional LED displays through modular integrated design.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: An integrated LED control card and display device with integrated power supply and control functions includes an integrated control card that integrates a power module, a data processing unit, a signal transceiver, and a storage module into a modular integrated structure. The power module provides a stable power supply to the entire LED display system; the data processing unit receives and converts input signals into a display format compatible with the LED screen; the signal transceiver enables signal interaction between the control card and other modules and positions the control card itself; and the storage module stores display data, control programs, and related configuration parameters, achieving integrated functions of power supply, signal conversion, and data interaction.
[0007] Furthermore, based on the signal transceiver in the integrated control card, an automatic screen connection mechanism is constructed. The signal transceiver detects and locates the installation position of each control card in real time. Then, the data processing unit drives the corresponding display unit to automatically match adjacent display modules, completing the division and splicing of display areas. This eliminates the need for manual positioning and calibration operations, thus removing the inefficiency and error problems caused by manual calibration steps.
[0008] Preferably, an adapter board and plug-in module combination design is adopted, which supports quick plug-in connection of the power supply and receiver card. Standardized plug-in interfaces reduce the number of redundant interfaces, simplify connection lines, reduce assembly complexity, and also facilitate subsequent maintenance.
[0009] Preferably, a display device includes at least one of the aforementioned integrated control cards and corresponding LED display units. The integrated control card is embedded in a slot on the back of the LED display unit, connected to an external power supply via a power interface, and communicates with an external terminal via a network interface. The LED display units achieve splicing display through the automatic screen-connecting mechanism of the integrated control card. The beneficial effects of this invention are as follows: 1. Significantly improved installation efficiency: Through the modular design of the integrated control card and the automatic screen connection mechanism, the separate installation of independent power supply boxes and control cards, complex wiring and manual calibration steps in the traditional solution are eliminated, reducing the installation steps by more than 60% and greatly improving the installation and deployment efficiency of LED display equipment; 2. Effective cost reduction: The integrated control card integrates multiple independent components into one, reducing the overall size of the equipment. At the same time, it reduces the number of parts such as cables and interfaces used, reducing cable loss. This not only reduces the production cost of the equipment, but also reduces subsequent maintenance costs. 3. Enhanced display and operational stability: The integrated design reduces signal interference issues when multiple independent components work together, ensuring stable transmission of display signals and improving the display effect of the LED screen. At the same time, the simplified structural design also reduces the probability of failure and improves the stability of equipment operation. 4. High scalability: The integrated control card's built-in storage module supports remote firmware upgrades, enabling updates to control programs and functions according to actual application needs, thus improving the device's scalability and lifespan.

[0012] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0013] Reference Figure 1-3 An LED control card and display device integrating power supply and control functions are disclosed. The hardware architecture of the integrated control card is specifically implemented. The control card has a built-in high-performance data processing module. This module uses a dedicated signal processing chip, which can quickly and accurately convert externally input video, image and other signals into digital signal formats compatible with the LED screen, ensuring the clarity and smoothness of the displayed content.
[0014] Furthermore, the power module 303 integrates a high-efficiency switching circuit with a wide voltage input design, capable of adapting to different external power supplies. When an external power supply signal is connected, the switching circuit automatically responds and activates the entire system, providing a stable operating voltage for the data processing unit, signal transceiver, storage module, and LED display unit.
[0015] Furthermore, the signal transceiver adopts a bidirectional communication chip, which supports high-speed data transmission and the sending and receiving of position detection signals, ensuring stable and efficient signal interaction between control cards and between control cards and display units.
[0016] Furthermore, the storage module uses a high-capacity flash memory chip to store display data, control programs, calibration parameters, and other information, while also supporting fast data reading and writing to ensure system response speed.
[0017] Working Principle: In use, the integrated control card is first embedded into the dedicated slot on the back of each LED display unit. Through the combination of the adapter board and the plug-in module, the integrated control card and the LED display unit are quickly connected without complicated cable connections. Then, external power is connected through the power interface 304 on the integrated control card. After the switching circuit in the power module 303 detects the power supply signal, it automatically activates the system, and each module begins initialization. Subsequently, the signal transceiver starts the positioning function, detects and obtains the position information of itself and adjacent control cards in real time, and transmits the position information to the data processing unit. The data processing unit automatically allocates the display area of each display unit according to the obtained position information and drives the display unit to complete the matching and splicing of adjacent modules. The user establishes a communication connection with the integrated control card through the terminal software to accurately calibrate the color, brightness and other parameters of the LED display screen. After calibration, the LED display device 1 can be put into normal use.
