Fine/ Small/ Narrow pixel pitch (NPP) is a LED display with pixel pitch less than 2.5mm, mainly including P2.5, P2.0, P1.8, P1.5 and other smaller pixel pitch.
(Add: Pixel pitch is the distance from the center of one pixel to the center of adjacent pixel in LED display, unit is mm. The smaller the pixel pitch,the shorter the viewing distance and the higher the resolution. And it also means when viewing the same size display at a certain distance, the smaller the pixel pitch, the clearer the picture)
