Gloshine of Shenzen was showing its 250 x 250 mm indoor LED modules which can be quickly assembled and changed. They are intended for indoor use and the display at the show was a 2.8mm unit. The displays can be maintained from the front, using magnets to get access and using two screws for better alignment.
The cabinets can be set at 0º or ±6º and the units can be automatically locked together by a single operator. It should be available in around the July time frame as it is going through CE & UL approval. One of the features of the design is that there are no screws holding the module onto the cabinet.
The company was also showing its latest dance floor which has a smaller pitch and was being shown with a car parked on it. They can also be used for outdoor rental applications.
