The table shows the standard build for this P3.91 Outdoor LED Display Screen. Cabinet size, brightness and control system can be changed per project; the final datasheet is issued with the PI before production. Cabinets are tested against IEC 60068 for temperature, humidity and vibration.
How the numbers work on a real wall
The arithmetic behind this P3.91 Outdoor LED Display Screen is simple enough to check before you order: 960÷3.91 = 246 pixels across each cabinet and 960÷3.91 = 246 down, so six cabinets in a row resolve 1,476 pixels at 5.76 m wide. Viewing distance follows the pitch – 5.9 m before the pixel structure disappears, 12 m before body copy reads cleanly. Because the cabinet divides into 18 standard 320×160 mm modules, a replacement module is never a custom order.
Product details
Larger size equals better visibility. Better visibility means more interested customers or audience members. For this reason, the 19.7′ x 11.5′ P3.91mm outdoor video wall LED is the most recommended for outdoor digital signage and advertising. It has a viewing distance of at least 8 for an optimum viewing experience – meaning high resolution, smooth motion and absolutely no pixelation. The P3.91 is often best deployed for churches, houses of worship and trade shows, where the audience is viewing the screen at a distance. Additionally, it brings an unmatched brightness rating of 5500 NITs. Also, its IP65 rain protection makes it incredibly durable and versatile for all environments.
The LED wall is delivered primed and ready to start using, in addition the customer has a maintenance service available, 24/7. We include free shipping, nationwide and activate a 3-year warranty on the LED wall and all of its components. Make sure to ask about our installation services!

Installation and service access
Outdoor cabinets are sealed to IP65 with a breathable membrane valve, so pressure changes do not pull moist air inside. The rear door, fan filter and cable glands are the three service points that need access, and all three are reachable from the maintenance walkway.
For coastal sites we apply an anti-corrosion coating to the cabinet and use stainless fixings. 3-year warranty on modules, power supplies and receiving cards; spare parts held in Shenzhen for five years after the order.
P3.91 Outdoor LED Display Screen: frequently asked questions
Will this P3.91 Outdoor LED Display Screen survive a coastal or high-humidity site?
Yes, with the coastal option: epoxy coating on the cabinet, stainless screws, conformal-coated driver boards. Humidity above 85% year-round is the case where that option pays for itself.
What is the lead time for a P3.91 Outdoor LED Display Screen order?
7-12 working days for standard P3.91 cabinets, 15-20 days if the order includes steel structure and on-site commissioning. Sea freight to most ports adds 18-35 days depending on the route.
How many spare modules should I keep?
Budget 2-3% of modules plus one power supply per 20 cabinets. A spare module is a five-minute swap, so the stock is insurance against downtime, not a repair plan.

Yes. Send the wall width, height and viewing distance and our engineer returns a cabinet layout, a resolution map and a power estimate within 24 hours. Non-standard sizes are cut from the same cabinet family, so spares stay interchangeable.
