What are the main parts of the LED screen?

Many components assemble the full-color LED screen.

Today, BIBI LED will share the 2 most important parts of LED screens: parts and components of. Let’s take a look.

1. What are the important parts of LED display?

Ribbon cable

The ribbon cable plays a key role in connecting various components in the LED display.

It is mainly used for connection between modules, between modules and cabinets, and between control systems and cabinets. The quality and stability of the ribbon cable directly affect the overall performance and display effect.

Common LED display ribbon cables include a variety of specifications and types, such as 16P pins, 40/60/80/100/120cm, and other different lengths of cables to meet the needs of display screens of different sizes and resolutions.

In addition, the cables’ materials are also varied, such as pure copper, tinned copper, etc., to ensure good conductivity and durability.

Fan

Although fans are not essential parts for all LED displays, they are indispensable heat dissipation components in some high-power, large-size, or long-running displays.

The fan circulates air to reduce the internal temperature of the display, ensuring that the LED module and electronic components operate within the normal operating temperature range, thereby extending the service life of the display and improving its stability.

It is worth noting that with the development of technology, some high-end LED displays have adopted more advanced heat dissipation technologies, such as heat pipe heat dissipation, liquid cooling, etc.

These technologies can replace traditional fan heat dissipation methods in some cases.

IC (Integrated Circuit)

IC is one of the core control components of LED display screens. It is mainly responsible for processing and controlling various signals and data on the display screen.

In LED display screens, there are many types of ICs, including driver ICs, control ICs, etc. The driver IC is responsible for converting the input signal into a signal that the LED module can recognize and control the brightness and color of the LED。

The control IC is responsible for receiving signals from computers or other control devices and converting them into images and videos that can be displayed on the display. High-quality ICs can ensure that the display effect is more delicate, clear, and stable.

2. What are the important components of LED display screens?

Power supplier

The stability and performance of the power supply determine the performance of the display.

There are many different brands for the power suppliers on the market today, such as Meanwell ( Our long-term cooperation partners ), G-energy, Changlian, Greatwall, etc.

The quantity of the power suppliers are required for the led screen is calculated based on the power of the LED modules, and the calculation for a different model of the LED models are different.

The quantity of the power suppliers has also related to the power consumptions and led screen electricity cost.

LED Screen Cabinet

There is a lot of different design, size, and material for the LED screen cabinet.

And the purpose of each cabinet is different, Like the steel cabinets mostly for the outdoor or indoor fixed installation; Die-Casting aluminum mostly for the rental purpose application; front opening cabinet mostly for the outdoor front maintenance access applications.

You need to discuss more details of your projects with your LED screen manufacturers about the LED cabinet solution before they make the quotation for you.

LED modules

The LED module is the most important part of the LED screen.

And the LED modules are composed of a PCB board, mask, LED pixels, and the basement.

The LED screen is composed of the LED modules, the large-screen-led screen that we see.

Control system

The LED display control system is an important part of the LED screen display.

The video transmission is sent to the receiving card of the full color LED screen through the sending card and the graphics card.

And then the data on the hub card is transmitted to the single-line or single-row to the LED module through the data cables, and then each full color LED module is also connected through the data cables.

It is how does the LED display control system works.

Metal structure frame

The metal structure frame is the supporting structure of the LED display screen, which is usually made of high-strength, corrosion-resistant metal materials such as aluminum alloy or steel.

It carries the weight of the entire display screen and provides a stable installation foundation for other components. At the same time, a good metal structure frame design can also improve the heat dissipation performance of the display screen.

The stability and load-bearing capacity of the metal structure frame directly affects the safety and service life of the display screen.

Transmission cable

The transmission cable is an important part of connecting the various components and devices of the display, including data cables, power cables, etc.

They are responsible for transmitting control signals, video signals, power, etc., to ensure that all parts of the display can work together.

The quality of the transmission cable and the correctness of the connection method directly affect the display effect and stability of the display.

Main controller

The main controller (also known as the control system or control host) is the “brain” of the LED display, responsible for receiving external signals and controlling the display content of the entire display.

It usually includes a high-performance processor, a large-capacity memory, and a rich interface circuit, etc., which can process complex image and video data and control the display in real-time.

The performance of the main controller directly affects the display effect and response speed of the display.

Dedicated display card and multimedia card

A dedicated display card is a graphics processing card designed for LED display, which can output signals suitable for the display format of the display.

A multimedia card is used to convert various multimedia signals (such as video, audio, etc.) into a format that the display can recognize.

They can optimize the processing process of image and video data and improve the display effect and picture quality. The use of a dedicated display card and multimedia card can further improve the display effect and compatibility of the display.
