The HUB board in the LED display screen is a vital component, which plays a key role in data transmission and control in the entire display system.
The following is a detailed introduction to the characteristics and functions of the HUB board.
Basic concept and positioning of the HUB board
The HUB board, also known as the Hub adapter board or Hub interface board, is one of the core components responsible for data transmission and signal processing in the LED display.
It is located between the control system and the display unit, acting as a bridge and link to ensure effective communication and data transmission between the control system and the display unit.
Composition and structure of the HUB board
The HUB board usually consists of the following key parts:
1. FPGA chip
As the core component of the HUB board, the FPGA chip has a high degree of flexibility and programmability. It is responsible for receiving instructions from the control host and performing corresponding processing and distribution according to the instructions. The performance of the FPGA chip directly affects the data processing capability and response speed of the HUB board.
2. Driver IC
The driver IC is a key component in the HUB board for driving the LED display lamp beads. It controls the on and off and brightness of the LED lamp beads according to the instructions of the FPGA chip to achieve the display effect. The performance and stability of the driver IC have an important impact on the display effect of the LED display.
3. Power management module
The power management module is responsible for providing a stable power supply for the HUB board. It usually includes power conversion circuits, filter circuits and protection circuits, etc., to ensure that the HUB board can obtain a stable power supply under various working environments.
Working principle of the HUB board
The working principle of the HUB board can be summarized as the following steps:
1. Receive instructions
The HUB board receives instructions and data from the control host through the interface.
2. Process instructions
The FPGA chip decodes and processes the received instructions to generate corresponding control signals and data signals.
3. Distribute signals
The processed control signals and data signals are distributed to the various modules of the LED display through the interfaces and lines on the HUB board.
4. Feedback processing
The HUB board is also responsible for receiving feedback signals from various modules of the LED display, such as temperature, voltage, etc., and transmitting these signals back to the control host for processing.
Functional features of HUB board
1. High-speed data transmission
HUB board adopts high-speed data transmission technology to ensure that control signals and data signals can be transmitted to each module of LED display in real time and accurately.
