Abstract
Large format display systems are described that are reconfigurable between an open configuration designed for performing maintenance on the system and a closed configuration designed for normal operations of the display system. In the closed configuration, the display screen is intentionally subjected to a substantial amount of tensile force to advantageously stabilize the display screen. That substantial tensile force is generated by a sturdy stationary frame that the display screen is anchored against in the closed configuration. When the display system is reconfigured to the open configuration, the display system is no longer anchored against the stationary frame. The process of reconfiguring the display system from the closed configuration to the open configuration includes relieving most of the tensile force applied to the display screen using adjustable tensioning mechanisms of the display systems.
