The parameter affecting the viewing distance of an LED display screen is the pixel pitch. First, understand this premise: computer monitors typically have a resolution of 96 ppi/inch; television monitors typically have a resolution of 72 ppi/inch. Common LED display screen specifications include P1.25, P1.56, P1.667, P1.875, and P2, where these values represent the pixel pitch of the LEDs.
The optimal viewing distance for an LED display screen is calculated as pixel pitch P (mm) x 1000 to P (mm) x 3000. This is a range. If we calculate based on the experience of viewing a computer monitor, we can use pixel pitch P (mm) x 2000. For a P2 LED screen, the viewing distance would be 4000mm, providing a viewing experience similar to sitting in front of a computer monitor.
