P4.81 LED module-mask

P4.81 LED module mask kit

The P4.81 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.

P4.81 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 P4.81LED 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 P4.81 LED Module

The P4.81 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 P4.81 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 P4.81 LED module

The P4.81 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.

P4.81 LED module-PCB

P4.81 LED module PCB circuit board

The PCB circuit board undergoes the wave soldering process and is equipped with a green oil oxygen barrier layer to safeguard the circuit against moisture and oxidation, thereby enhancing its service life.
During the assembly and installation of the display, the variance in thickness between the PCB and the rear body significantly impacts the product’s flatness.
Unlike other suppliers who opt for 0.8mm or 1.0mm thick PCBs to minimize material costs, we consistently select a 1.6mm thickness for enhanced stability and durability.
This choice not only ensures the stability of the PCB board but also results in a 30-40% reduction in energy consumption compared to standard components.

P4.81 LED Module Power Supply

Our P4.81 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.

P4.81 LED module-card

Receiving Card of P4.81LED 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 P4.81 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 P4.81 LED module

P4.81 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;

P4.81 and the following small pitch support COB HOB technology. Better protection and realistic effect.
