LED display P several good

P in the LED display generally represents the pixel spacing, and the value behind P mainly refers to the distance between two LED beads, which is often referred to as the point spacing. If the value of point spacing is smaller, the higher the unit pixel, the clearer the image quality and the more expensive […]
