Frequently Asked Questions
The pixel pitch refers to the distance between the center points of two pixels. The pixels, also called dots or clusters, are made up of 3-in-1 RGB LED lamps—red, green, and blue. This allows our screens to reproduce trillions of colors, unlike CMYK, which is used for digital printing and has a limited color range. P3.91 simply means there are 3.91mm between each LED lamp cluster, whereas a P3 screen has a 3mm distance, and a P5 has 5mm.
The pixel pitch affects how the display looks at different viewing distances, so a P3.91 display is optimized for audiences roughly 10 meters away. There are plenty of other considerations, like screen size, configuration, and the type of media you want to display.

P3.91 LED Display– Your Ultimate FAQ Guide
The P3.91 LED display is a kind of digital screen that was made by combining many tiny LED panels to create a large display.
The number “3.91” means the distance in every LED pixel that is measured by millimeters.
This distance affects the clarity of the display and how close a person can look at the screen without seeing individual pixels.
The P3.91 LED display is usually seen in indoor places where viewers are on a medium distance screen.
Because of the balanced quality of displays and flexible design, it is mostly used in events, stages, rental setups, halls and public spaces.
This FAQ is intended for people who are new to LED displays to understand how it works, where it should be used and what are the practical things to be considered in daily use.
What does “P3.91” mean in a P3.91 LED display?
The “3.91” refers to pixel pitch or the distance from the center of a LED pixel to the next pixel.
In the P3.91 LED display, its distance is 3.91 millimetres.
It is important because the pixel pitch is one important factor that affects the display’s quality and the desired viewing distance.
If the pixel pitch is smaller, the finer and clearer the display when viewed in a closer distance.
The P3.91 is in the middle- not so fine like P2 or P1.5 for close viewing, and not so big like P8-P10 for a distance viewing.
That’s why the P3.91 is advised for medium-range viewing where the audiences are mostly a few meters away from the screen.
The understanding of P3.91 will help a person in choosing the right display based on their location and uses.
It doesn’t mean it’s better or worse than others, but the purpose is different.
The “P3.91” is chosen because it has a balance in clarity, screen size and its practical uses, especially in places that don’t require high resolution but want a smooth and clear display.
How does a P3.91 LED display work?
The P3.91 LED display works by thousands of tiny LED lights that were arranged in an accurate and organised form.
