Parking Screen Overview Specifications Case Study


Parking Screen


Product Introduction:

By embedding LEDs on some sections of ordinary traffic signs, the effect of dynamically displaying road traffic conditions can be achieved.
Shows the red, green, and yellow colors specified by the national standard to indicate that the road is crowded, unimpeded, and slow.
In strict accordance with the 23828-2009 standard selection, design, production and testing.

Compared with traditional traffic signs, it has the advantage of traffic conditions;
More general LED variable information board, with energy-saving and easy-to-understand advantages;
It has been widely used in Beijing and Shenzhen.

It is applied to indoor main roads in major cities at home and abroad.
