Detailed Description:
1. Adjusted brightness
Energy-saving technology ensures that brightness can be adjusted.
It also has the best broadcasting effect as the brightness of the
rental led display can be adjusted;
2. Better heat-dissipation effect
Although without fan, it still has better heat-dissipation effect
with our four layers PCB design and aluminum cabinets design;
3. Ultra-thin and light
Exquisite material and technique make it has ultra-thin and light
cabinets: the thickness of the cabinet is only 77mm and it weights
just 6.4KG/set;
Popular Application:
1. Stage background;
2. Night club;
3. Wedding ceremony;
