Abstract

The invention discloses an environmental outdoor LED fluorescent display screen comprising a box. The box comprises a plurality of modules. Each module comprises an LED lamp surface and a control element surface. A hood covers each LED lamp surface of each module. Steady-persistence fluorescent powder layers are formed on the outer surfaces of the hoods in a partial or whole manner and excited by light rays emitted from LED lamps to light. A transparent anti-radiation layer is formed on each steady-persistence fluorescent powder layer and totally covers the same. Thus material of the fluorescent powder layers cannot volatilize in the air, environment pollution factors are reduced, and meanwhile the transparent layers do not affect lighting degree of the fluorescent layers.
