ToggleWhat is a P4 LED Display?
A P4 LED display is a pixel pitch of 4.0mm LED video wall. This means the distance between the centers of two adjacent pixels is exactly 4mm. The smaller the pixel pitch, the higher the pixel density, which leads to sharper and more detailed images. P4 LED screens can offer high clarity at a competitive cost. Therefore,they are suitable for medium-to-large 4–12 meters away.
What is the Resolution of a P4 LED Display?
Resolution depends on both pixel pitch and physical screen size. For example, a 1 square-meter panel offers a resolution of 250×250 pixels (62,500 pixels total). A standard 960x960mm LED panel yields 240×240 pixels. A 4×3 meter P4 LED wall brings a resolution of 1000×750 pixels, which is ideal for HD video content and dynamic graphics.
Which LED Packaging Technology is Used in P4 LED Displays?
P4 LED displays typically use SMD packaging. In general, it is SMD1921 for outdoor models and SMD1515 for indoor ones. SMD technology integrates red, green, and blue diodes into a single module, achieving a color depth of 16-bit per channel and a contrast ratio up to 5000:1. SMD offers several advantages:
- Better Color Mixing: Smooth, vibrant colors without visible color separation.
- Wider Viewing Angles: Consistent brightness and color from various angles.
- Compact Design: higher pixel density in a smaller area.
- Improved Durability: Resistant to vibration and environmental stress.
Key Features of P4 LED Displays

High Definition
With a 4mm pixel pitch and a resolution of 62,500 pixels per square meter, P4 LED displays bring exceptional clarity. Supporting 1080p or higher resolutions on larger panels, they can display intricate details remain visible.
Superior Display Effect
P4 LED displays have refresh rates up to 3840Hz, eliminating flicker for smooth visuals. With brightness levels of outdoor 5000–6000 nits or Indoor 800–1200 nits and a 16-bit grayscale, they can bring vibrant colors and high contrast for advertisements or presentations.
Environmental Protection
With energy-efficient designs, P4 LED displays consume approximately average power 200–300 W/m², reducing electricity costs by up to 30% compared to traditional displays.
Adaptability
These displays support multiple configurations, such as cabinet sizes like 960x960mm or 500x1000mm. Compatible with both fixed and rental setups, they adapt to diverse applications, such as, outdoor billboards, indoor auditoriums and stage event.
Wide Viewing Angle
By offering viewing angles up to 160° horizontally and 140° vertically, P4 LED display sxreen maintain consistent color and brightness across wide perspectives.
Lightweight and Slim Design
Constructed with magnesium or aluminum alloys, P4 LED displays weigh as little as 5.8kg per cabinet (1000x250x33mm). Slim profiles, as thin as 33mm. Our indoor p4 display is suit able for space-saving installations due to wall-mounted indoor setups.
Easy Installation and Maintenance
In gneral, fixed P4 displays are modular designs with 320x320mm or 320x160mm modules. It can supporti front and rear maintenance. Moreove, you can choose wireless HUB connections and hot-swapping technology to reduce setup time by 20% and enjoy uninterrupted operation, minimizing downtime for maintenance.
Low Brightness with High Grayscale
With 16-bit grayscale and brightness as low as 100 nits, P4 displays maintain rich, nuanced visuals in dim environments.
Extended Shelf Life
Built with robust materials, P4 LED screens achieve lifespans of over 100,000 hours ,approximately 11 years of continuous use. In addition, IP65-rated outdoor models withstand harsh conditions, including temperatures from -20°C to 50°C and humidity up to 90%.
