Indoor LED module is very popular in the market nowadays.
How much do you know about it?
This article focuses on introducing readers to the components of indoor led display modules and how to use led display modules to create led display screens.
In the end, there is a FAQ part to explain further questions.
Let’s get started!
Part One What is the indoor LED module?
1.what is the indoor LED module?
As the name implies, indoor LED display modules are LED modules used indoor, and indoor LED display modules play an essential role in commercial conference, school,church,wedding,etc.
2.Components of indoor LED module
(1)Components
Indoor LED module includes eight components.
Beads, PCB, IC, Frames, Connectors, Cables, Screws or Magnets, Resistors, and Capacitors.
Among all these, only LEDs, PCBs, ICs, and Cables need our attention.
(2)Suggestion
A.Beads
The most important part of the LED wall is the LED beads.
The quality of LED beads determines the clarity of the display.
Here we recommend three brands of LED beads, Nationstar, Kingligh, and Hongsen.
Their brands are more mature and will definitely make you satisfied.
B.IC Driver
A high refresh rate and high grayscale driver IC can make the full-color LED module panel reproduce the most realistic color, and will not make our eyes uncomfortable after a long viewing.
Normally, a good indoor LED module is generally provided with driver ICs such as MIB5153, MBI5124, ICN2153, ICN2038S, etc.
3.Features of indoor LED display module
(1) Pixel Pitch
LED walls for indoor use are often placed in scenes where people can view them at a close distance.
Therefore, in order to create a better visual effect, the indoor LED module needs to provide a clearer and more accurate image.
This requires the pixel pitch of indoor LED display modules to be small.
Common indoor LED display module pixel pitch includes P1.86mm, P2.5mm, P2.976 mm, etc.
(2) Protection capability
Due to the stability and safety of the indoor environment, the protection ability of indoor LED display modules is average.
Dust-proof, waterproof, heat dissipation, and other features are far less than outdoor LED display modules.
(3)Maintenance
Indoor LED display module has a low failure rate.
However,it is difficult to repair because it mostly only support back-service,and you need to dismantle it before repair.

Part Two How does the LED module make LED wall?
1.What do we need for building an led wall?
✓LED module
According to your needs, you need to determine the size of the LED module before you buy it and whether it is an indoor LED display module or an outdoor LED module.
The process described in this article uses the indoor LED module as a sample.
✓Control system
The size of the LED display screen determines the number of sending and receiving cards.
In addition, you need to choose a synchronous control system or an asynchronous control system for your LED wall.
✓ Display playback software
Including computer system software and special software for controlling the LED display.
✓ Supporting equipment
For example, computers, audio, video processors, etc.
2. How to use Led module makes led wall?
Step 1 Make the Borders for Indoor LED Screen
✓ Calculate the size of the LED display
✓Prepare the border material, complete the welding of the frame, and use two angle hooks to fix the frame on the top of the wall.
Step 2 Power supply and receiving card installation
✓Check the positive and negative polarity of the power supply carefully, use the fixing strip and fixing plate to fix the power supply on the frame just installed.
✓Receiver card link data cable, fixed in the frame.
Step 3 Receiver card connection
✓According to the real demand of your LED display, we will make the connection instruction diagram for you, so that it is easy for you and your team to operate the connection between the receiving card and the module.
Step 4 Installation of indoor LED module
✓Our recommendation is that the modules are installed in the order of bottom to top, from the middle to the sides.
This will make no gap between modules and achieve a tight fit.
Step 5 Debugging
When installing the LED modules, make sure to debug them in time to check if there are any problems with the installation.
It will be troublesome to wait for all modules to be installed before finding problems.
✓So we suggest doing a test when the first receiver card has been installed.
Part Three FAQ of indoor led module
Customized-size indoor LED modules are available.
If you want to design your LED module size, you need to inform your needs in advance.
It is important to note that generally customer-specific dimensions of LED modules are more expensive.
It is not recommended to use different led modules on the same LED display.
Each LED module has its own features, and when mixing them, it does not produce good results.

Welcome to subscribe!
A. Keep the environment dry
Do not let the electronic components of the LED display get wet.
Excessive humidity can lead to corrosion of the parts and cause short circuits, which leads to damage to the LED display.
B.Circuit safety
Try not to use it in thunderstorm weather
C. Do not play with a single color for a long time
All-white, all-red, all-green, and another all-bright screen will lead to excessive heating of the power line, causing damage to the LED beads.
D.Time of use
Do not use it for a long time without interruption, and do not make it unused for a long time.
Both of these are the wrong way to use.
E.Cleaning
After using it for a period of time, the screen needs to be wiped clean with a towel and alcohol in a timely manner.
F.Avoid touching sharp objects
The surface of the LED display is composed of LED beads, which are very fragile.
So we should try to avoid sharp objects scratching their surface.
Part Four Conclusion
We believe that when you finish reading this article you must have a better understanding of indoor LED modules.
If you are still interested in the outdoor LED module, welcome to read our blog： Introduction of Outdoor LED module, not to be missed!
We are looking forward to hearing from you, and thank you for supporting.
