According to the working environment, LED display can be divided into indoor led screen, outdoor led screen and semi-outdoor led screen. There are some data in theory which can reflect the relationship between the pixel pitch and the best viewing distance (sheet 1)

In the actual application, because of the limitation of led display installation environment and identify ability, led display’s smallest viewing distance is mean the shortest distance that can identify the text and picture showing. The shortest viewing distance and led specification are on below（sheet 2）
