P3.91 LED module mask kit
The P3.91 LED module’s mask kit provides protection for the LED beads from dust and moisture, enhancing the visual display.
It is made from fiber-reinforced PC material with high light transmittance and enhances visual effects, contrast, and displays.
The outdoor module also utilizes an oil-spraying process to restore the screen’s color and efficiently dissipates heat from the module’s surface for stable operation of the LED display.
P3.91 LED Module Back cover
Ordinary LED modules usually have only 2 or 3 reinforcement strips, which easily cause the module to sink inward, and the display effect is uneven, uneven, and has color difference.
However, LEGIDATECH’s P3.91 LED module adopts a full back cover encapsulation reinforcement design, which makes the module flatter, without depressions or protrusions, and the display effect is perfect. Secondly, this packaging method enhances the integrity of the module, the modules are tightly connected, and the possible gaps during splicing are eliminated. Regardless of the viewing angle, the picture is unified and smooth.
Strong Magnet of P3.91 LED Module
The P3.91 LED module has been specifically engineered to securely fasten LED display screens in various environments. Its durable permanent magnets generate a powerful magnetic force, guaranteeing stability and enabling front maintenance. This removes the need for extra maintenance space and streamlines the screen replacement and installation process.
With its cutting-edge design, the P3.91 LED module delivers a smooth and effortless experience for users. Moreover, the module’s top-notch materials and advanced technology ensure a prolonged lifespan and outstanding visual performance.
Driving IC of P3.91 LED module
The P3.91 LED display module universal driver IC determines the refresh frequency of the LED display. Generally, the refresh frequency reaches 1920HZ. The price of the LED display universal driver IC is the cheapest and is the most selected by other suppliers.
However, this will affect the display screen and often cause “caterpillars”. ”, display problems such as stroboscopic lines and uneven brightness caused by insufficient refresh.
LEGIDATECH uses a higher-priced PWM IC, which is often used in indoor rental LED displays, outdoor stage LED displays, and church LED displays.
the PWM IC can make the refresh rate of the LED display reach 3840HZ, it can satisfy the audience’s shooting of the color displayed on the screen.

P3.91 LED Module Power Supply
Our P3.91 LED module power supply is 200V, one power supply can carry 6 modules and one 2.5 square 220V cable can carry 20 power supplies. This ensures that each module can withstand enough current and voltage to achieve higher brightness and more stable display.
Moreover, the power supply design of our LED modules adopts highly efficient conversion technology and strict over-current and over-voltage protection, which effectively prevents module damage caused by power supply problems.
At the same time, our LED modules are also characterized by low energy consumption and high efficiency, reducing overall operating costs.
Receiving Card of P3.91 LED module
There are many brands of receiver card, but LEGIDATECH only cooperates with famous brand novastar and use novastar MRV412 uniformly. One receiver card can take 12 modules, 2 wide and 6 high. This ensures a clear and smooth picture while saving cost and guaranteeing quality for customers.
The receiver card of P3.91 LED module is mainly used to receive and analyze the video signal to ensure the picture can be accurately and smoothly presented on the display.
The receiver card also has the function of adjusting parameters such as brightness, contrast and color to meet the needs of different application scenarios.
SMD COB HOB of P3.91 LED module
P3.91 LED display module is a smaller pitch indoor LED display module, the most common types are HOB COB and SMD. SMD (Surface Mount Device) LED module adopts more advanced technology.
SMD LED modules utilize more advanced technology. the LED beads are mounted on a printed circuit board (PCB), allowing for higher pixel density and clearer picture performance.
COB and HOB are chips placed on the PCB board. COB is a condensation technology that allows the LED dots to emit light uniformly, enhancing the display effect; HOB is a thermal condensation technology that makes the LED light source more concentrated, improving brightness and clarity;
P3.91 and the following small pitch support COB HOB technology. Better protection and realistic effect.
E Structure of P3.91 LED Screen
In addition to P3.91 LED modules, LEGIDATECH can also be equipped with specialized E-structures. Whether it is an indoor control room or a wall fixed mounting structure, it can be exclusively customized.
E-structure makes the splicing between modules more tightly, effectively reduces the seams, and improves the coherence and aesthetics of the overall picture.
From modules, fittings and wires, mounting structure to transportation, customers can purchase everything they need for project installation in one stop. It greatly saves customers’ purchasing time and cost.
P3.91 LED Module Used in Indoor Event
P3.91 LED Module Used in Outdoor Stage
P3.91 LED module is widely used in outdoor stages. It has high brightness, high definition and excellent color expression, and can maintain good visual effects in any lighting environment.
At the same time, P3.91 LED module is also waterproof and dustproof, and can operate stably under harsh weather conditions to ensure the smooth progress of the performance.
