The price of a P20 LED display is primarily driven by the pixel pitch (20mm), which is designed for long-distance viewing (typically 20-200 meters). Key technical factors include Brightness levels, where outdoor displays should exceed 5,500-7,500 nits for sunlight visibility, and the Refresh Rate, which should be at least 1,920Hz to avoid flickering on camera. Additionally, the choice between DIP (Dual In-line Package) and SMD (Surface Mounted Diode) technology significantly impacts cost; DIP is often preferred for P20 outdoor use due to its superior weather resistance and higher brightness.
