1. What is P3.91 LED Display?

The P3.91 LED display is widely used because it combines sharp image quality with versatility. Before we look at its different types and applications, it’s important to understand what the “P3.91” actually means and why it matters for image clarity and viewing distance.

1.1 What Does LED P3.91 Mean?

The P3.91 LED display gets its name from the pixel pitch of the screen. Pixel pitch is the distance between the centers of two pixels. For P3.91, this distance is 3.91 millimeters.

A smaller pixel pitch means higher resolution and sharper images. That’s why P3.91 LED screens are clear and detailed, even when used for close viewing indoors or medium-distance outdoor displays.
