Pixel pitch is a key term in the field of display technology, particularly when it comes to LED screens and digital displays. It refers to the distance between the centers of two adjacent pixels, measured in millimeters (mm).

Here’s a breakdown of what pixel pitch means and why it’s important:

Definition:

• Pixel Pitch: The distance from the center of one pixel to the center of the adjacent pixel on a display. It is typically measured in millimeters (mm).

Importance:

1. Resolution and Clarity:

   • Smaller Pixel Pitch: Results in a higher resolution and better image clarity because the pixels are closer together. This is ideal for applications where fine details are important, such as in high-definition video walls or close-viewing displays.
   • Larger Pixel Pitch: Generally means a lower resolution, which might be suitable for applications where the viewer is farther away, such as large outdoor LED billboards.

2. Viewing Distance:

   • The appropriate pixel pitch depends on the intended viewing distance. Smaller pixel pitches are suited for closer viewing, such as in indoor environments, while larger pixel pitches are typically used for displays viewed from a greater distance, like outdoor advertising screens.

3. Cost and Efficiency:

   • Displays with smaller pixel pitches usually cost more due to the higher density of pixels and the technology required to achieve such fine resolution. Conversely, larger pixel pitches might be more cost-effective for larger, less detailed displays.

Applications:

• Indoor Displays: Often use smaller pixel pitches (e.g., 1.5mm, 2mm) to deliver high-resolution images and videos that look sharp up close.
• Outdoor Displays: Generally use larger pixel pitches (e.g., 8mm, 10mm) to ensure visibility and clarity from a distance, as well as to withstand environmental conditions.

Understanding pixel pitch helps in selecting the right display technology for specific needs, balancing factors such as image quality, viewing distance, and budget.
