Abstract: Disclosed is a display device including a display module, a frame located in rear of the display module, a step difference adjusting unit located between the display module and the frame to adjust a distance between the display module and the frame, a worm shaft providing a driving force to the step difference adjusting unit, and a controller controlling the display module to output a marker at a position related to the step difference adjusting unit. Accordingly, it is possible to adjust a height or level difference between the display modules disposed adjacent to each other without separation of the display modules, thereby shortening the installation time.

Abstract: Disclosed is a display device, including a display module, a frame located in rear of the display module, a step difference adjusting unit located between the display module and the frame to adjust a distance between the display module and the frame, and a worm shaft providing a driving force to the step difference adjusting unit, the step difference adjusting unit including a holder magnet having the display module coupled to a rear surface thereof, a leveling screw extending in a rear surface direction from the holder magnet to adjust an amount of insertion into the frame, and a clutch module selectively providing the driving force of the worm shaft to the leveling screw. Accordingly, installation time may be shortened by adjusting a height or level difference between the display modules disposed adjacent to each other without separation of the display module.
