What are the Main Components and Parts for an LED Display

If you are looking to configure, order, or manufacture a custom LED screen, learn more about its components and structure here!

LED Display Parts

The various parts that make up screens all work together to deliver different contents to the viewer. They vary in a variety of sizes and shapes, but they all share the same fundamental parts. Individual LED panels make up an LED screen, whether it is indoor or outdoor. A cabinet, a power supply, a sending and receiving card, and an LED module are all components of an LED panel. Diodes, driving ICs, and a PCB board are all included in each module.

However, the LED display structure does not end there, and we will explore it in more detail further.

LED Display Components

LED Screen package

Metal Frame

The outer frame of an LED screen typically uses die-casting aluminum alloy or iron metal. The size of the screen and the frame’s bearing capacity are taken into consideration while choosing outdoor screen frames. The exterior frame can be embellished with aluminum.

LED Module

Whether it be an indoor or outdoor LED display, LED modules make it up. LED modules come with drive ICs, PCB boards, LED lights, and module frames. The module also includes a mask.

Display Cabinet

The display panel serves as the screen’s main structure. It is made up of apower and signal lines plus modules.  The indoor and outdoor screens’ LED display is consist of many cabinets.

Display Controller

The display controller consists of a computer, a transmitting card, and a receiving card. The receiving card should be fitted in the cabinet, and the sending card inside the computer. Typically, a receiving card is needed for a cabinet. The controller’s job is to smooth out the input RGB digital visual communication signals while also modifying the grey scale and rearranging them to produce all the control signal kinks.

Switch Power Supply

The power supply transforms 220V or 110V AC into a variety of DC power to support all sorts of circuits inside the LED display.


Flat cables are used to carry the data from the LED display as well as other control signals produced by the main controller to the screen.

Scanning Control Board

Its duties include producing different scan signals and duty cycle grey control signals, as well as buffering data.

Video Processor

The LED video processor is a high-performance image processing and control device launched for full-colour LED displays. It can receive and process many different video graphic signals simultaneously and display them on the full-color LED.

Mounting Accessories

LED displays also include various mounting brackets and other installation accessories for seamless integration of the screen into a space.
