LEDs – How to Verify The Quality
To learn the optimal viewing distance for an LED display and choose the correct pixel pitch, understand that smaller pixel pitches (e.g., P3) are for closer viewing, while larger pitches (e.g., P10) are for greater distances. You can estimate a recommended viewing distance using the formula: Pixel Pitch (mm) x 2 = minimum optimal distance (meters), and Pixel Pitch (mm) x 3 = maximum optimal distance (meters). The appropriate pixel pitch depends on the closest viewing distance of your audience, the desired image quality, budget, and the display’s application.
Understanding Pixel Pitch
- Pixel Pitch (P): This refers to the distance between the centers of two adjacent pixels on the LED display, usually measured in millimeters (mm).
- Resolution: A smaller pixel pitch (e.g., P3) means more pixels in a given area, resulting in higher resolution and a clearer image at close distances.
- Inverse Relationship: A smaller pixel pitch allows viewers to be closer to the screen without seeing individual pixels.
