3, The choice of P value in the range of visual distance. "P" refers to the distance between adjacent two pixels (dots) called pixel spacing, also known as dot spacing, in millimeters. The smaller the point spacing, the higher the pixel density, the clearer the picture, the more information capacity, the closer the distance for viewing. Therefore, the general indoor Full-color LED display of the P value selection is less than outdoor. Therefore, in a certain viewing range of the clarity of LED display, is also the choice of Full-color LED display specifications important reference.
