Small Pixel Pitch LED Display Modules vs. Cabinets: Which Is Better?

When people choose small-pixel LED displays, they can be divided into two options: LED modules and LED cabinets. Some customers may not know the difference between the module and cabinet structures of LED displays. Which one is better? Next, IAMLEDWALL will analyze it from a professional perspective, hoping to provide you with some help.

Generally speaking, in terms of the overall display effect and the convenience of installation and disassembly, the LED display cabinet is better than the LED module due to the LED cabinet has better flatness, which brings the overall effect of splicing and the integrated display effect of the picture are better. 

At the same time, the installation of the cabinet is faster than that of the LED module, because the cabinet is larger in size and easier to disassemble, and will not collide with each other to cause lamp beads. Hence, it is more conducive to the stability of long-term use.

What is an LED module of LED display?

LED display module

LED display Module is the basic unit that makes up an LED display. A complete LED display is formed by splicing multiple LED modules. Different pixel-pitch LED lamp beads are distributed on the modules. Many modules are spliced together to assemble some large LED displays. For example, indoor P2, P2.5, P3, P4, P5 and other specifications are also mostly made of LED modules. 

Advantages of LED display module

Mature technology: The use of LED modules is very common and the technology is also very mature. It is a structure currently used in outdoor LED screens and indoor LED displays above P2. The LED cabinet is basically only used in small-pitch LED displays and was only introduced in recent years.

Low price: Whether it is during early installation or after-sales replacement and maintenance, the price of the LED module is much lower than that of the LED cabinet. It is easier to repair individual lamp beads if they die or fall off, and it is cheaper to replace them.

Disadvantages of LED display module

Troublesome installation: Since the LED module size is relatively small, if it is a large-size LED display project, hundreds or thousands of LED display modules will be used for installation, so the installation is relatively cumbersome and slow.

The flatness is difficult to adjust: after the LED modules are spliced, there will be fluctuations between each other, and there may even be certain gaps. The flatness of the entire LED display is difficult to control.

What is an LED display cabinet?

The LED display cabinet is composed of several LED display modules that can be combined and spliced. To meet different environments, coupled with a set of appropriate controllers (main control boards or control systems), display boards (or unit boxes) of various specifications and controllers with different control technologies can form many kinds of LED displays to meet different display requirements.

LED display cabinets have been introduced in recent years to reduce the impact of small-pitch LEDs on the lamp beads during installation, transportation, and disassembly. Currently, the small pixel LED displays cabinet are basically below P2, such as P1.86, P1.53, P1.25, and P0.9 etc, especially for COB packaged LED displays.

Advantages of LED cabinets

Large size and easy installation: The size of the LED cabinet is much larger than that of the LED module, so it is relatively simple to splice. Just stack multiple cabinets directly, and it is more convenient to adjust the seams.

High flatness: Due to the large size of the LED cabinet, the flatness of the entire LED display after splicing is better adjusted and the effect is better. There will be basically no unevenness and the overall display effect will be better.

Easy to disassemble: The LED cabinet can be made for front maintenance. If it is used on some occasions that often need to be disassembled, such as some temporary meetings, parties, etc., it will be more convenient to disassemble.

Disadvantages of LED cabinets

Higher price:  compared to the module, the price of the LED cabinet is higher than that of the LED module for an LED display at the same pixel pitch. 

The differences between LED display modules and cabinets 

The main differences between LED display modules and cabinets are size, pixel pitch, flatness after installation and price.

Size difference

Usually, the size of the LED module is relatively small. The current mainstream LED display modules are 160mm*160mm, 320mm*320mm, etc., while the size of the LED cabinet is relatively large, such as the mainstream small-pitch LED display cabinets are 480mm*480mm, 600mm*337.5mm, etc. The latter size is more popular with customers because the ratio of this size is designed to be 16:9, making it easier to maintain the conventional display ratio of the entire LED display.

The difference between pixel pitch

Most of the LED displays composed of LED modules have large pixel pitches that are basically between P2~P20, while the LED display cabinets are mostly used in indoor small-pitch LED displays, mainly used for below P2.

Difference in flatness

Since the size of the cabinet is larger, when it is installed into a large-size LED display, the flatness of the LED display spliced out of the cabinet is better, while the seams and concavity of the LED module splicing are often difficult to control. , which will directly affect the later display effect.

The difference in convenience between installation and disassembly

The board size of the LED module is relatively small, so the installation is slow and requires splicing piece by piece. The large size of the cabinet makes it more convenient to install, and it is also more convenient to disassemble and repair later. 

Price difference

In the composition of some small-pitch LED displays, you can choose to use cabinets or modules. For example, P2, P1.8, P1.5, etc. can also use modules, and choose to use modules. The price of the LED module will be cheaper than the LED cabinet. For some occasions with limited budget, the module will be more cost-effective.


The LED display cabinet has been gradually applied to the market in recent years. It is mainly used in the composition of small-pitch LED displays, especially P1.8, P1.5, P1.25, P0.9, etc. It is more convenient to install and disassemble, and has better flatness. While the price of modules is relatively low but not to easy install. When designing, the choice of whether to use an LED display cabinet or a module mainly depends on the LED display pixel pitch and other factors such as whether it is frequently disassembled and the budget.
