Abstract: A display device includes a flexible display panel; a rolling driver including a rolling shaft connected to the flexible display panel and a rotation motor which rotates the rolling shaft; a housing which receives the flexible display panel in a rolled state, where a first opening is defined in the housing for unrolling and rolling the flexible display panel; a rolling stopper coupled to the flexible display panel; and a rolling controller which controls the rolling driver such that the rotation motor rotates in a clockwise or counterclockwise direction. The rolling controller rotates the rotating motor in a direction opposite to a rotating direction of the rotation motor for a previous rolling to unroll the flexible display panel. The rolling controller rotates the rotating motor in a same direction as a rotating direction of the rotation motor for a previous unrolling to roll the flexible display panel.

Abstract: A flexible display device may include a display module unit configured to project an image, a frame, and a connecting unit. The frame supports the display module unit. The connecting unit is coupled to the display module unit and the frame, and is adjustable so as to allow an amount of curvature of the display module unit to be adjusted.
