The pixel pitch of an LED display screen is the distance between two adjacent pixels, while pixel density is the number of pixels per unit area (usually 1 square meter). The following is a detailed explanation of these two concepts:
Pixel Pitch Definition: Pixel pitch is the distance between two adjacent pixels and is one of the important technical parameters of a full-color LED display screen.
Impact: The smaller the pixel pitch, the higher the pixel density per unit area, the more information can be displayed, and the closer the suitable viewing distance.
The larger the pixel pitch, the lower the pixel density per unit area, the less information can be displayed, and the farther the suitable viewing distance.
Selection Basis: Viewing Distance: The placement of the display screen and the viewing distance are important factors in choosing the pixel pitch. Generally, the viewing distance for a full-color LED screen = pixel pitch (mm) * 500/1000, and the optimal viewing distance for an LED display screen = pixel pitch (mm) * 3000/1000.
Application Scenarios:
For outdoor LED displays, P4 or P5 are generally used for short distances and small areas, while P8 or P10 are used for long distances and large areas.
For indoor LED displays, P2.5 to P3 are generally sufficient, while P4 is used for displays at greater distances.
Pixel Density: Definition: The number of pixels per unit area (usually 1 square meter), a crucial indicator of LED display clarity.
Impact: Higher density means more LEDs per unit area, resulting in higher clarity.
Higher density also means more LEDs are needed per unit area, leading to higher prices.
Common LED Display Models and Pixel Density Correspondence:
P2 Indoor Small-Pitch Full-Color LED Display = 250,000 dots/square meter
P2.5 Indoor High-Definition Full-Color LED Display = 160,000 dots/square meter
P3 Indoor Full-Color LED Display = 111,111 dots/square meter
P4 Indoor Full-Color LED Display = 62,500 dots/square meter
Outdoor P4 Full-Color LED Display = 62,500 dots/square meter
Outdoor P5 Full-Color LED Display = 40,000 dots/square meter
Outdoor P6 Full-Color LED Display = 27,800 dots/square meter
Outdoor P8 Full-Color LED Display = 15,625 dots/square meter
P10 Outdoor Full-Color LED Display = 10,000 dots/square meter
