"Pixel pitch" in the LED industry refers to the distance between individual LED pixels in an LED display. It is measured in millimeters (mm) and is a key specification that determines the resolution and viewing distance of an LED screen.

1. Resolution:

   • Smaller Pixel Pitch: More pixels per unit area, resulting in higher resolution and greater detail. This is suitable for closer viewing distances.
   • Larger Pixel Pitch: Fewer pixels per unit area, resulting in lower resolution. This is acceptable for larger displays intended to be viewed from a distance.

2. Viewing Distance:
   

   • The appropriate pixel pitch is often determined by the viewing distance.
     For example, a smaller pixel pitch is ideal for indoor displays where viewers are closer to the screen, while a larger pixel pitch is sufficient for outdoor displays viewed from afar.
     

What will different pixel pitch affect?

1. Image Quality:
   

   • Smaller pixel pitch provides sharper and more detailed images, which is crucial for applications like digital signage, retail displays, and indoor events.
   • Larger pixel pitch may result in visible pixelation if viewed too closely, but this is generally not an issue for outdoor billboards or large-scale displays.

2. Cost:

   • Displays with a smaller pixel pitch are typically more expensive due to the higher density of LEDs required.
   • Larger pixel pitch displays are generally more cost-effective, making them suitable for applications where ultra-high resolution is not necessary.

3. Application Examples:

   • Small Pixel Pitch (e.g., 1mm to 2.5mm): Used in applications like indoor retail displays, corporate environments, TV studios, and control rooms.
   • Medium Pixel Pitch (e.g., 3mm to 6mm): Suitable for medium-sized indoor and outdoor displays where the viewing distance is moderate.
   • Large Pixel Pitch (e.g., 7mm and above): Ideal for large outdoor billboards and stadium displays where viewers are far away from the screen.
     

Understanding pixel pitch is essential for selecting the right LED display for a specific application, ensuring that the display meets both visual and budgetary requirements.
