LED technology is the latest and the best in terms of the audio visual technologies out there and it is still evolving. There is a strong emphasis in making LED displays energy efficient, cost efficient and light weight apart from other quality requirements. Hence, LED cabinets are also now expected to be lighter in weight. Resulting to the gradual shift from the iron cabinet, aluminum cabinet, to the cast-aluminum and die cast aluminum as the weight of the cabinet is lighter. 


Cast aluminum and die cast-aluminum cabinets are the latest of the cabinets used for LED casing. Rental LED display are quite flexible for easy packaging and lifting, high refresh rate, gray scale are widely applied to the stage renting.
