Fine-pitch Essential Series | Signal Detection Status Indicator Status indicators and a check button are located in the main frame of the cabinet structure and can be conveniently accessed from both the front and back of the unit. Easy Alignment in Z-direction A uniform tool can be used for X/Y/Z 6-axis adjustment between panels. Modules can be easily adjusted in Z-direction to deliver a distortion-free image. Front Serviceability Front access reduces the need to access the unit from behind for more convenient maintenance. Easy-handling Lightweight Cabinet It's lightweight and easy to install, effectively reducing the risk of damage during installation. A full set of LED screens is still light, reducing strain on the structure holding the screens. Signal / Power Redundancy With an additional controller and power unit, a backup controller activates if a signal transmission error occurs, preventing a screen blackout error (Signal Redundancy). The product also offers Power Redundancy as an option. Two power units are provided in a single LED cabinet, and one activates to provide power when the other fails. Service Maintenance is easy and fast with the optional LG ConnecedCare service, a cloud service solution provided by LG. It remotely manages the status of displays in client workplaces for fault diagnosis and provides remote-control services that better support the stable operation of clients' businesses.
