Pixel pitch in the context of LED video walls refers to the distance between the center of one pixel to the center of an adjacent pixel. It is typically measured in millimeters (mm) and is a crucial specification in determining the resolution and image quality of the LED display.

A smaller pixel pitch generally indicates a higher pixel density, which can result in a clearer and sharper image. The pixel pitch is essential for understanding how closely individual pixels are packed together on the screen. The relationship between pixel pitch, resolution, and viewing distance is significant:

1. Smaller Pixel Pitch:

• High Contrast Ratio: OLED displays provide excellent contrast ratios compared to other display technologies. Each pixel emits its own light, allowing for true blacks and vibrant colors.
• Wide Viewing Angles: OLEDs offer wide viewing angles without a loss in image quality, making them suitable for applications like TVs and smartphones.

2. Larger Pixel Pitch:

• Lower Resolution: Larger pixel pitch means fewer pixels within a given area, resulting in lower resolution. While this may be acceptable for larger displays or situations where viewers are farther away, it may lead to a less detailed image when viewed up close.
• Longer Viewing Distance: Displays with larger pixel pitches are generally suitable for situations where viewers are at a greater distance from the screen, such as outdoor installations or large event venues.

The choice of pixel pitch depends on the specific requirements of the application, the size of the LED video wall, and the expected viewing distance. It’s important to strike a balance between achieving the desired image quality and ensuring that the display is suitable for the intended audience and environment.
