Abstract
An object is to provide a technique that enables making an adjustment from a direction where a video display surface is located, in order to provide inconspicuous seams between one of video display devices and other adjacent video display devices even when there are no workable spaces behind the video display devices. A multi-display system includes a plurality of LED display tiles, a position adjusting mechanism, and a pull-out mechanism. The position adjusting mechanism includes a lock mechanism that switches between a locking state and an unlocking state. When the lock mechanism is in the locking state, each of the LED display tiles is fastened in a retraction position. When the lock mechanism is in the unlocking state, each of the LED display tiles is movable between the retraction position and a pull-out position by the pull-out mechanism while being floated and supported via an elastic support portion.
