LED Display Technology · Rental

The LED display screen rental business is one of the service industries that has flourished in recent years. The stage or background of important activities such as TV studios, large-scale performing arts activities, opening ceremonies of important events, sports competitions, corporate celebrations, etc. cannot be separated from the participation of LED displays. The text, pictures and video programs played on the LED display screen create a changing stage charm for various activities and greatly enhance the level of performing arts activities.

Features

  • Adopt front/rear maintenance for magnetic module and rear maintenance for power supply, control box, and accessories, which makes installation and disassembly convenient and quick.
