Here are some of the highlights of the outdoor P3.91 LED video wall display for stage background

Precise picture quality and stable output

The P3.91 outdoor LED display features a high pixel density (65,536 points/㎡) and excellent close-up clarity, making it ideal for text, dynamic images, and virtual stage applications. It uses SMD1921 black LEDs with copper supports, ensuring pure color rendering and significant contrast improvement. With precise brightness correction and a unified Gamma algorithm, it ensures seamless color matching. The display supports 14-16bit grayscale and HDR processing, and is compatible with high frame rate video recording. The color temperature can be adjusted from 2500K to 9300K, adapting to various lighting conditions and providing stable, realistic image quality.

To ensure the stability of the equipment in high-frequency performances and long-term use scenarios, the P3.91 display module has a lifespan exceeding 100,000 hours. The internal components are selected from industrial-grade solutions, achieving an MTBF (Mean Time Between Failures) of over 50,000 hours. The overall screen failure rate is controlled below 0.03%, significantly surpassing industry standards. It also offers a 2-3 year full-screen warranty (customizable for extended service), along with round-the-clock technical support and localized spare parts storage, ensuring uninterrupted operation for key projects such as performances and broadcasts.

Highlight resistance to sun, real outdoor vision

1. Adjustable brightness range 800-5500cd/m².

2. Contrast 5000:1, combined with black lamp and matte mask technology.

3. Light sensing automatic adjustment module (optional) to adapt to different weather and time period brightness changes.

4. The surface is equipped with a high-transparency anti-glare PC mask, and the anti-reflection treatment effectively controls the "white haze" phenomenon.

Even when viewed under direct sunlight at noon, the content can remain clear and sharp. It is suitable for all-weather places such as the main stage of a square, city publicity, and a sunlit theater.

Highlight Resistance To Sun, Real Outdoor Vision

All-weather use, no compromise in harsh environment

1. The box is made of die-casting aluminum alloy, and the whole box is CNC precision processing to prevent rust and fall

2. The front and rear IP65 protection level is ensured by using nano-coated waterproof glue, double-sealed rubber ring and waterproof plug to ensure that the power line and signal line interface meet the waterproof standard.

3. It can operate stably in the temperature range of-20°C to +60°C, and pass the high and low temperature cycle test for 100 hours without failure.

Suitable for rainy season performance, seaside square or outdoor operation in sandy weather, all-weather stable operation.

The box structure design is professional, and the installation and maintenance are one step ahead

The installation of outdoor LED displays requires addressing complex technical challenges, including load-bearing assessment, wind resistance design, high-precision splicing, and waterproof wiring, which are particularly challenging in high-altitude or open environments. For example, small-pitch products like P3.91 require precise positioning of the enclosure, and during installation, systems for lightning protection, drainage, and heat dissipation must be designed in tandem. The overall construction process involves transportation, hoisting, and temporary power supply, requiring a professional team to manage the project, with strict requirements for time and cost control.

P3.91 The outdoor LED display screen has undergone professional optimization, featuring a modular hot-swappable design that supports both front and rear maintenance, significantly reducing the complexity of maintenance. Equipped with IP65 protection, an independent cooling system, and redundant power and signal backups, it effectively enhances stability and environmental resistance. With remote diagnostics, inspections, and 24-hour technical support provided by ASRAM, it ensures long-term reliable operation under high-frequency use, significantly reducing lifecycle maintenance costs.

3. The top and bottom of the box are equipped with aviation socket hanging points, supporting various structural forms such as hoisting, stacking and frame fixing.

No matter where the audience is on the main stage, on both sides or diagonally in front, the picture is consistent and the color is not biased, which improves the overall immersion of the audience.

The signal link is flexible and stable to meet the requirements of complex field systems

1. The default configuration is a 2-in-2-out signal link (double backup design), which supports automatic switching of hot backup signals and does not black screen or lose communication.

2. The control system is compatible with NovaStar, HuiDu and other mainstream brands, and the built-in receiving card supports color space DVI/HDMI synchronous input.

3. Input interface: HDMI / DVI / SDI / VGA / USB / LAN

4. It can be connected to multi-screen, live streaming and remote playback control systems

5. Support APP wireless control and USB disk offline playback (asynchronous scheme)
