Compared with the traditional LED display, LED projecting a small spacing feature is smaller dot pitch. In practice, Hebei led display installation, the smaller the dot pitch, the higher the pixel density Hebei led display installation, suitable viewing distance is more recent, on the contrary, is suitable farther viewing distance. Small pitch LED screen in order to achieve the best visual effects Hebei led display installed, have the best line of sight, the user can perform simple calculations, there is an established formula that best viewing distance = spacing /0.3~ 0.8. The smaller the dot pitch, the higher the cost of a small pitch LED display, so the actual purchase in Hebei led display installation, the user should consider their own cost, demand, application and other factors.
