6 is of short pixel pitch. P6 is for indoor use because of its short pixel pitch. P6 is used in SMD3528, which has the features of high brightness, short viewing distance, big size, high definition, and small pixel pitch. SMD has better viewing angle and color mixture and it has a bright future. P6 is used indoor, so it does not need waterproof. There are two best viewing distances of P6 led display because there are 2 ways to calculate the best viewing distance: one is by the pixel pitch, one is by the diagonal. One is the minimum best viewing distance:as short as 3.6 meters, the other is maximum best viewing distance: as far as 81.6 meters. The pixel density of P6 is high which is 27777. So p6 has high resolution. P6 usually adopts scanning 1/8. The module compoisition of the PH6 is 32*16, and the module size is 192*96, the cabinet size is 960*960.
