P3.91 LED Module Type
According to the different environments in which they are used, P3.91 LED modules can be divided into two categories: indoor and outdoor. The differences between them are brightness, protection level of the shell and the environment they are suitable for.
Indoor LED module
Commonly used in conference rooms, exhibitions, stage backgrounds and other occasions. The display effect is very delicate and the colors are also rich.
Outdoor LED Module
Key Features
High-quality SMD
Using high quality SMD led lamp bead, no damge lamp, uniform current, same brightness, higher gray level
Wide viewing angle
Modular design:
High Refresh Rate
Carefully selected LED drivers s allow P2.5 LED panel to deliver high refresh rates up to 3840Hz, resulting in flicker-free operation in module applications.
Note:
♦ If you only need to buy a P3.91 LED display module to build a screen, you need to inform the supplier of the screen size, installation location, installation method, etc.
Because the installation and splicing of the module will be slightly more complicated than the LED screen with a cabinet.
♦ If you are replacing an old module, you need to inform the supplier of the pictures and details of the original cabinet and module.
Because the modules of the rental screen are divided into left and right (the position of the tooth holes is different), so as to confirm whether the new module can match the rental.

P3.91 LED Module Details
P3.91 LED Module Aging Test
All P3.91 LED display modules will undergo a 48-72 hour aging test after production. To detect whether the LED lamp beads have color cast and damage.
The aging test can detect the stability, brightness, color temperature and other performance of the LED module to ensure the long-term stable operation of the product and reduce the occurrence of failures.
Aging tests will be carried out before shipment, and waterproof tests will be carried out for outdoor P3.91 module displays to ensure that both the LED module and the screen have good performance.
