The Ultimate Guide to LED Display Screens in 2025
What is an LED display?
An LED display is a flat-panel display device that uses light-emitting diodes (LEDs) as light-emitting pixels. It is a modular electronic display device characterized by high brightness, high contrast, and vibrant colors.
Its applications are increasingly diverse, ranging from large-scale stage events and commercial advertising screens to small information displays and traffic signage. This demonstrates the importance of LED displays.
Components of LED display screens
The large LED display screens we see are all assembled from LED boxes or smaller units of LED modules.
This method can greatly reduce the cost of the entire process from production to installation of LED display screens, effectively improve the efficiency of each link, enhance the flexibility of LED display screens, and can be assembled into different sizes and shapes according to different usage scenarios and customer needs. This is an advantage that traditional display media cannot match.
LED module
LED module, also known as LED light board, is the smallest detachable component unit at the application level of LED display screens. LED modules are generally composed of LED lamp beads, signal input/output interfaces, chips, kits, PCB substrates and power input interfaces.
(1) LED lamp beads. That is, light-emitting diodes, which are the display light source of LED display screens.
(2) PCB substrate. As a hub platform for signal transmission, its function is to connect the control chip, LED lamp beads, signal input/output interfaces, and power input interfaces through PCB circuits.
After the components are soldered, the PCB substrate becomes a unit board that can be lit, which is commonly known as an LED module (light board).
(3) LED kit. Usually made of plastic, it is mainly used to fix and protect the LED module. It can fix the LED module to the LED box structure, or directly fix it to the steel structure, and is used to assemble the LED display screen.
However, not all LED modules need to be fixed with a kit. Many LED modules have integrated bolts for fixing, so this type of LED module does not require a kit.
(4) IC chip. Its main function is to control the control signal output by the system through the receiving card, thereby controlling the on and off and luminous intensity of the LED lamp beads.
By accurately controlling tens of thousands of pixels on the LED display screen, the required image can be displayed. Conventional LED modules generally include power amplifier chips, decoding chips (including CMOS power tubes), driver chips, etc.
(5) Signal input/output interface. The control signal output by the control system is connected from the receiving card to the LED module through the flat cable, and the signals between the LED modules are connected through the flat cable for the display control of the LED module.
LED cabinet
The LED cabinet is generally the basic component unit of the LED display screen, which is composed of LED modules arranged according to certain rules.
(1) LED module. It is the main light-emitting component of the LED cabinet. All components in the LED cabinet are designed to ensure the normal and stable operation of the LED module.
(2) LED cabinet structure. The material is generally iron, die-cast aluminum and carbon fiber, etc. It is mainly used to fix the internal components of the LED cabinet to facilitate the assembly of the LED display screen. In addition, it can also play a good protective role.
(3) Switching power supply. Generally, LED display screens need to be powered by a DC low-voltage power supply. The commonly used DC voltage is 2.8~5V. T
he commonly used mains power in my country is 220V/50Hz. There are many mains power standards used abroad.
In order to expand the applicable area of LED display screens, the switching power supply input voltage used in the general LED industry is AC100~240V and 50/60Hz, and the rated output power is mostly concentrated in 150~400W.
(4) Receiving card. It is the control center of the LED cabinet display. It can output different control signals according to the different driver chips and driver circuits of the LED cabinet, thereby controlling the normal display of the LED cabinet.
(5) Adapter board. It can rearrange and combine the data control signals output by the receiving card according to the definition of the LED module signal input interface, and transmit the signal to the LED module through the cable or direct interface connection. Its size and shape are determined by the internal structure of the LED cabinet.
LED Display Classifications
Classification by Installation Environment
1. Indoor LED Displays
Indoor LED displays are designed specifically for indoor environments. They typically feature lower brightness, smaller pixel pitches, and a closer viewing distance, yet are capable of displaying high-definition, vibrant content.
They are commonly used in indoor shopping malls, conference rooms, churches, exhibition halls, and other locations for information dissemination, brand presentation, and multimedia interaction.
2. Outdoor LED Displays
Outdoor LED displays typically offer high brightness and excellent protection (IP65+). They can be used in direct sunlight and can be viewed from several dozen meters away.
Therefore, they have larger pixel pitches (such as P4, P6, P8, and P10). They are suitable for outdoor applications such as commercial districts, highways, and stadiums.
Based on Processing Methods: There are three main types
Direct-In-Package (DIP) LED Displays
DIP (Dual In-Package) was a widely used packaging method for early LED displays. LEDs with two metal pins are soldered through a circuit board. Each LED consists of three independent lamps: red, green, and blue.
Due to their low pixel density, extremely high brightness, and strong UV and high-temperature resistance, DIP LED displays are primarily used for outdoor, long-distance viewing, such as highway billboards, large outdoor advertising screens, and stadium fence screens.
SMD LED Display (Surface Mount Device)
SMD (Surface Mounted Device) solders the LED pins directly to the circuit board surface, without penetrating the board. It is currently the most common LED packaging technology and is suitable for most indoor and outdoor full-color LED displays.
Its characteristics include high brightness, wide viewing angles, and excellent color consistency. SMD LED displays offer a good price-performance ratio and are suitable for various applications, including advertising screens, stage screens, and commercial displays.
COB LED Display (Chip-Scale Package)
COB (Chip-On-Board) packaging directly packages multiple LED chips onto a PCB, resulting in a smaller pixel pitch and higher integration. Compared to SMD, COB LED displays offer better resistance to impact, moisture, and dust.
They are suitable for indoor locations requiring high stability and precision, such as high-end conference rooms, surveillance centers, and control and command systems.
Based on Application
1. Rental LED Displays
These are widely used for temporary applications such as stage shows, concerts, exhibitions, and press conferences. Rental LED screen feature quick installation and removal, a lightweight structure, and durability and reliability.
They typically utilize a die-cast aluminum enclosure with a quick-lock design, making them easy to move and maintain frequently.
2. Fixed Installation LED Displays
These are suitable for long-term, fixed installations. Their stable structure typically requires no frequent installation or removal, requiring only that they meet environmental and viewing requirements. They prioritize durability, energy efficiency, and ease of maintenance.
