The Meaning of Pixel Pitch in LED Displays

Some people who are new to LED displays may wonder why the term "pixel pitch" exists. Technically speaking, this is because LED displays are composed of many small LED lamp beads arranged in a grid. As a result, there will always be some spacing between these lamp beads. The distance between one lamp bead and another is referred to as "pixel pitch" or "dot pitch" in the LED display industry. The smaller the spacing between lamp beads, the more lamp beads can fit into the same area, resulting in a clearer display.

How is Pixel Pitch Expressed?

When you try to understand an LED display and someone mentions its pitch, it is usually described as P1, P2.5, P5, etc. For example, P2.5 means that the distance between the lamp beads on that LED display is 2.5 mm.

What Are the Direct Impacts of Pixel Pitch?

Clearer Screen Display​

The smaller the pixel pitch of an LED display, the clearer the image will appear on a screen of the same size.

Better Color Performance​

A smaller pixel pitch allows for richer colors and a wider color gamut.

How to Choose an LED Display with the Right Pixel Pitch Based on Usage Scenarios?

A very simple rule is: if the viewing distance is close, choose a smaller pixel pitch. If the viewing distance is far—such as more than 2 meters—you can appropriately select the pixel pitch based on the distance. For example, the pixel pitch of LED displays at concert venues is generally P4 or higher.
