Knowledge & Support

The Resolution of an LED display is defined by the total number of pixels it contains. More pixels equal higher resolution, which generally translates to finer image detail and improved visual quality.

What Is Pixel Pitch?

Pixel pitch is the distance between the center of one pixel and the center of the next, usually expressed in millimeters (mm).

Smalle pixel pitch → LEDs are closer together, creating higher pixel density and sharper resolution.

Larger pixel pitch → LEDs are spaced farther apart, resulting in lower resolution but often more cost-effective for large displays.

In summary:

Lower pitch = higher resolution, sharper images, closer optimal viewing distance

Higher pitch = lower resolution, better for long-distance viewing, more budget-friendly.

2. How Pixel Pitch Determines Resolution 

Resolution = Number of horizontal pixels × Number of vertical pixels.
For the same cabinet size, a P1.5 display holds far more pixels than a P3 display, so images appear sharper and text remains crisp.

The smaller the pitch, the higher the pixel density—and the higher the achievable resolution.

How to Choose the Right Pixel Pitch

When evaluating pixel pitch for your LED screen, consider two main factors:

1.Viewing Distance

The closer your audience, the smaller the pitch should be.

A widely used rule:

Optimal viewing distance (m) ≈ pixel pitch (mm) × (1.2 ~ 2）

Example: A P10 display is best viewed from about 12–25 meters away.

2.Resolution Needs

For detailed video playback, presentations, or branding, a smaller pitch ensures crisp visuals.

For large-scale signage or outdoor billboards where viewers are far away, a larger pitch works well.

Conclusion

A smaller pixel pitch delivers sharper, higher-resolution images, but comes at a higher cost and requires careful consideration of viewing distance. 

For many outdoor projects, a medium or large pitch can provide excellent visibility and return on investment.

The right choice always depends on your audience distance, application, and budget goals.
