The price of LED screens is primarily driven by Pixel Pitch (P); a smaller pitch (e.g., P1.2 vs P4) results in higher resolution and cost. Buyers must also evaluate the LED Lamp Brand (such as Nationstar or Kinglight), as high-end lamps offer better color consistency and longevity. Additionally, Refresh Rates (≥3840Hz) are essential for broadcasting to avoid flickering, and Brightness Levels (measured in nits) must be at least 5,000-7,000 nits for outdoor use to remain visible under direct sunlight.
