The Led display screen is composed of led beads, and the led display screen with small spacing means that the spacing between two lamps is smaller. The traditional definition method of led display screen is the distance between two lamps, for example, P 10 means the distance between two lamps is 10mm, P8 also means the distance between two lamps is 8mm, and so on. The point spacing below P2.5 (including P2.5) is collectively referred to as the small-pitch led display screen. Liard is a company specializing in the production of LED screens and the founder of small-pitch LED products.
