What is the difference between P3 and P4 LED?

(1) Price Difference

Generally, the price of a P3 LED module is higher than that of a P4 LED module due to its higher resolution capabilities and enhanced visual clarity.

(2) Resolution details

The core difference lies in pixel density. A P3 LED panel has approximately 111,111 pixels per square meter, whereas a P4 LED panel contains 62,500 pixels. The smaller pixel pitch results in a higher density, providing closer details and sharper images.

(3) Optimal Viewing Distance

Different pixel pitches translate to different optimal viewing distances. For P3 LED screens, the optimal distance starts at 3 meters, whereas for P4 LED screens, the optimal viewing distance begins at 4 meters.

The P4 indoor LED module features the latest black 2121 LED technology, providing deeper blacks and outstanding contrast for vivid image representation. The highly stable driver ICs provide seamless control over LEDs, delivering flicker-free performance with a high refresh rate of up to 3840Hz. Furthermore, the 1.2mm thick multi-layer corrugated board with high elasticity prevents module deformation, maintaining screen flatness.

High refresh rates eliminate display flicker, ensuring moving images look smooth. This makes P4 modules optimal for dynamic applications such as broadcasting studios, retail spaces, stages, churches, control rooms, and commercial advertisement setups where vibrant, seamless content is key.

Frequently Asked Questions (FAQ)

What does "P4" mean in an LED display?

P4 indicates a pixel pitch of 4mm, which represents the distance between the center of one LED pixel and the center of the adjacent pixel. This spacing translates to 62,500 pixels per square meter.

What is the optimal viewing distance for a P4 LED screen?

The optimal viewing distance for a P4 LED screen is 4 meters (approximately 13 feet) or more. This makes it perfect for medium-sized indoor spaces like churches, retail outlets, and stages.

How does a P4 LED display compare to a P3 LED display?

P3 LED displays feature a higher pixel density (around 111,111 pixels/m²) compared to P4 (62,500 pixels/m²). P3 offers higher clarity at closer viewing distances but generally comes with a higher cost. P4 is more cost-effective for larger viewing distances.

Are P4 LED modules suitable for outdoor use?

No, these specific P4 LED modules are designed for indoor applications, featuring an IP40 rating and a brightness range of 600 to 1,000 nits, which is optimized for controlled indoor lighting.

What are the key advantages of high refresh rate (3840Hz) in P4 displays?

A high refresh rate of 3840Hz eliminates screen flickering. This is crucial for environments using cameras (like TV studios or live streams) to ensure clean images without black scan lines.

What dimensions are available for P4 LED modules?

The standard P4 LED modules are available in sizes of 320mm x 160mm (with a resolution of 80x40 dots) or 256mm x 128mm (with a resolution of 64x32 dots).
