1. What Is LED Pixel Pitch?

LED pixel pitch refers to the distance between two LED pixels, measured in millimeters.

For example:

• P1.25 = 1.25mm pixel distance
• P1.86 = 1.86mm pixel distance
• P2.5 = 2.5mm pixel distance
• P3.9 = 3.9mm pixel distance
• P5 = 5mm pixel distance

The smaller the pixel pitch:

✔ Higher resolution
✔ Better close-up viewing experience
✔ More suitable for fine images and videos

The larger the pixel pitch:

✔ Longer viewing distance
✔ Lower cost per square meter
✔ Better for large outdoor applications

2. How Does Pixel Pitch Affect LED Display Quality?

Pixel pitch directly affects:

Image Detail

A P1.86 LED screen can display more details than P5 when viewed from a close distance.

Viewing Distance

A larger pixel pitch requires a longer viewing distance.

Example:

• P1.86 → indoor close viewing
• P3.9 → stage and rental applications
• P5/P6 → outdoor advertising

Project Budget

Generally:

P1.86 LED display costs more than P3.9 because it requires more LED chips and higher manufacturing precision.
