Abstract: Disclosed is a rollable display, which prevents slippage between a flexible display panel and a back plate attached to the flexible display panel for supporting the same. The rollable display has a feature in different patterns of the back plate for each area. In addition, the rollable display has a feature in that a display unit is foldable and non-foldable via a link unit so as not to be folded or rolled multiple times in the same direction.

Abstract: A display apparatus can include a flexible display panel including at least one bending area; a first mid-frame disposed on a rear surface of the flexible display panel at a central area of the flexible display panel based on the at least one bending area; a second mid-frame disposed on the rear surface of the flexible display panel at an edge area of the flexible display panel based on the at least one bending area, the second mid-frame being spaced apart from the first mid-frame; and a bending guide configured to maintain a bent angle between the first mid-frame and the second mid-frame.

Abstract: Provided are an adhesive and a flexible display including the same. The adhesive can avoid deformation and can easily return to the original state thereof upon unfolding by including an adhesive sheet on both surfaces thereof and performing treatment on specific areas to change the rigidity thereof and make the areas different in rigidity and thereby form a plurality of neutral planes.

Abstract: A patterned adhesive can prevent detachment and easily return to an original state even during repeated folding operations, and a flexible display including the same are discussed. The patterned adhesive includes a patterned adhesive layer so that it can easily return to an original state by formation of a plurality of neutral planes upon compression and extension through a folding operation.
