Outdoor led billboard (LED screen, display screen) can be roughly divided into outdoor led billboard and outdoor screen according to different applications. Since the application environment of outdoor led billboards is different from indoor screens, and the environmental conditions are relatively harsh, naturally there are higher requirements for LED luminescent materials and cabinets. Generally speaking, the LED of outdoor led billboard must use super bright luminous material.

At present, the three primary colors of red, green, blue, orange, and yellow LEDs required for color display have reached candela-level luminous intensity, achieving ultra-high brightness and full color, making the outdoor full color of the luminous tube The display becomes a reality. The luminous brightness is higher than 1000mcd, which can meet the needs of outdoor all-weather, full-color display. The large LED color screen can express the sky and the ocean and realize 3D animation. The new generation of red, green, and blue ultra-high brightness LEDs have achieved unprecedented performance.
Outdoor led billboard pixels are currently composed of many single-tube LEDs with three primary colors (primary colors) of red/green/blue. Commonly used products have two structures: pixel tube and pixel module. The pixel size is mostly 12-26 mm, and the pixel composition: monochrome is 2R/3R/4R, pseudo color is 1R2YG/1R3YG/1R4YG, true color is 2R1G1B and other composition forms.
