1. LEDs. we select super led tips with high brightness, broad viewing angle(H140degree, V140degree), all the LEDs are ageing for 72 hours before assembly,

when in modules, also aging for 72 hours, after assembly into a screen, still aging 72 hours. so the final LEDs are aging at least for 216 hours, up to 9 days.

2. Modules. we use SMD1921 3in1 pixel configuration to realise high brightness. you may find some lower price suppliers but also same brightness. if you note, maybe they use is not Nation star LEDs lamp, in this case, can cut down much cost but also cut down the life of the display. why? because to reach the same brightness and better waterproof, it is big square lamps from nation star unique design can do it. and our modules case is PVC, which is more durable and have a stronger ability in bask, anti-ultraviolet and Difficult to deformation than Plastic ones.

3. Cabinets. they are used in galvanized steel, or super lightweight Magnesium alumnium die casting cabinets, anti-salt, anticorrosive and waterproof.
