1、 The prerequisite is “low brightness and high gray”.
As a small spacing LED screen of the display terminal, we must first ensure the viewing comfort, so when purchasing, the primary consideration is the brightness. Relevant research shows that as an active source, LED has twice the brightness of passive light (projector and LCD) in terms of human eye sensitivity.
