1.Ultrathin and light weight: Each cabinet weighs only 7 kgs, easy to install and transport.
2.Noiseless: Die-casting Aluminum cabinets, fanless design with noiseless power supply.
3.Seamless: High precision up to 0.1mm.
4.Fast Installation and dismantling: connection lock between cabinets are patented, closely combined, safe, reliable and adjustable, 50 cabinets can be installed in one hour.
5.Front Service: Use patented spring bead positioning pin and connection lock, any defective cabinet can be removed easily without dismantling the whole screen.
6.Mask without screws: mask fixation uses patented snap Joints instead of screws, it takes only 25 seconds to assemble one module, much more convenient for maintenance.
7.Unique blanking circuit: high definition display by eliminating the row / line after-image without damaging the LED lamps.
8.Energy saving: low electric current, high-bright lamps, save 30% electricity.
9.High refresh rate, high gray level: using MBI driving IC, refresh rate is more than 4000HZ, the gray level is still high even under the condition of low brightness.
10.Color correction: support dot-to-dot correction, guarantee the consistence of LED color and brightness, No chromatic aberration for new screens.
11.Dual back-up: both power supply and system dual back-up are optional, reliable performance.
