LED Modules: These are the individual units containing multiple LEDs that form the basic building blocks of the display. Each LED module typically consists of a circuit board with surface-mounted LEDs, a driver board, and connectors for power and data.
-
Frame or Cabinet: The LED modules are mounted onto a frame or cabinet to create the final display screen. The frame or cabinet is typically made of aluminum or steel and is designed to provide structural support and protect the LED modules.
-
Power Supply: LED display screens require a power supply to provide the necessary voltage and current to power the LEDs. The power supply is typically located inside the frame or cabinet and is connected to the LED modules and other control circuits.
-
Control Circuit: The control circuit is responsible for processing the input signal and driving the LEDs in the correct sequence to create the desired image or video on the display screen. The control circuit can be located on a separate control board or integrated into the power supply.
-
Cooling System: LED display screens generate a significant amount of heat, so a cooling system is required to prevent overheating and ensure long-term reliability. The cooling system can consist of fans, heat sinks, or other methods to dissipate heat.
-
Protective Layer: A protective layer can be added on top of the LED display screen to protect it from environmental factors like moisture, dust, and impact.
