P4 Indoor LED Modules
Professional P4 Indoor LED Modules for Dynamic Stage Backgrounds
Engineered for system integrators and event production companies. We supply the best P4 indoor LED display module units tailored for seamless die-casting aluminum cabinet integration, offering high-refresh rates essential for broadcast and live event staging.

Technical Core Definition
System Definition: The P4 (4mm pixel pitch) Indoor LED module, sized at 256x128mm, is a core hardware component utilized in the construction of large-scale, high-definition digital displays.
Industrial Application: Primarily deployed in stage rental, corporate AV setups, and broadcast environments. It is mechanically compatible with industry-standard 512x512mm rental cabinets. Sourcing reliable P4 LED screen panels for sale ensures integrators can deliver flicker-free (up to 3840Hz refresh rate), color-calibrated video walls that meet rigorous event production standards.

Trusted by Event Production Partners
David M.
AV Integration Director
"The structural integrity of these P4 modules perfectly matched our existing 512mm die-cast aluminum inventory. Assembly time was cut down significantly, making our stage setups far more efficient."
Sarah Jenkins
Live Event Production
"Flickering on broadcast cameras was our biggest issue. Switching to this supplier's high-refresh P4 panels solved the problem instantly. The color saturation is outstanding."
Markus W.
Wholesale Distributor
"Procuring large batches has been seamless. The color uniformity is perfectly controlled across the 200 sqm we ordered, proving their strict LED binning processes are legitimate."
Wholesale & Technical FAQ
What is the minimum order quantity (MOQ) for bulk purchases of P4 indoor modules?
For wholesale and enterprise project procurement, our standard MOQ is 100 modules. However, for prototyping stage rental cabinets, we accommodate sample testing orders. Please consult our technical sales for project-specific arrangements.
What is the lead time for a standard 100 sqm P4 LED display project?
For a standard 100 square meter event rental project, production lead time is typically 10-15 business days following technical confirmation and deposit.
Do your P4 indoor LED modules have CE, RoHS, and FCC certifications for commercial use?
Yes, all our LED screen panels are strictly tested and compliant with CE, RoHS, and FCC standards, ensuring safety and legal compliance for installations in Europe, North America, and globally.
Which driving IC do you use? Can it achieve a high refresh rate to prevent flickering on cameras?
We utilize premium driving ICs capable of delivering up to 3840Hz high refresh rates. This broadcast-grade performance eliminates scan lines and flickering under professional video cameras, making it ideal for live event broadcasting.
How do you ensure color and brightness uniformity across large-scale batch orders?
We strictly control LED binning and use advanced calibration systems. By keeping the same batch of LEDs for one project, we eliminate mosaic effects and ensure perfect color and brightness uniformity across the entire video wall.
Are these 256x128mm modules perfectly compatible with standard 512x512mm die-casting aluminum cabinets?
Absolutely. The 256x128mm dimension is precisely engineered to integrate seamlessly into standard 512x512mm die-casting aluminum cabinets, facilitating rapid assembly and teardown for the rental industry.
