Key technical specifications for outdoor LED displays include pixel pitch, brightness, protection rating, contrast ratio, and lifespan. Pixel pitch (pitch) refers to the center-to-center distance between adjacent LED beads (unit: mm). A smaller pitch value results in a finer image; a smaller pixel pitch means more pixels per unit, leading to a clearer display.
Outdoor screens need to withstand strong light, typically requiring a brightness of at least 8000 nits, and over 10000 nits in direct sunlight. IP65/IP66 (dustproof and waterproof) protection ratings are common standards for outdoor screens. Contrast ratio is one of the factors to consider when selecting an outdoor display. The normal operating lifespan of an LED video display is generally 75,000 to 100,000 hours.
