LED display screen is a device widely used for information display and advertising. It usually consists of the following main components:

LED module: The core component of the LED display is the LED module, which includes many small LED lamp beads that can emit light. The size and density of the LED modules determine the resolution and brightness of the display. [Let me introduce to you in detail what is an LED display module? ](https://www.sostron.com/news/2369)

Driver circuit: LED modules require driver circuits to control the brightness and color of the LED. These circuits usually include control chips, power management units and data interfaces.

Control card: LED display control system (control card), also known as LED asynchronous controller, is the core component of LED graphic and text display. The LED display controller is responsible for receiving the screen display information from the computer serial port, placing it into the frame memory, and generating the serial display data and scan control timing required for the LED display according to the partition driving method. It is the core of the LED graphic and text display. part.

Power supply system: LED displays require a stable power supply to provide energy. The power supply system usually includes a power adapter and a power management unit to stabilize the power supply voltage at the level required by the LED module.

Enclosure and cooling system: LED displays are usually mounted in an enclosure to protect them from environmental factors. In addition, LED displays also require a heat dissipation system to cool the LED modules and electronic components to ensure their normal operation and extend their life.

Other parts: including waterproof system, lightning protection system, installation system, etc., which are set up to make the display screen more stable and reliable.

These components work together to enable LED displays to display a variety of images, videos, and text information, and are widely used in different indoor and outdoor application scenarios, such as billboards, stadiums, shopping malls, conference rooms, etc.
