Abstract
A rollable display may include a polyhedral drum and a flexible panel. The polyhedral drum includes a plurality of substantially flat surface portions and a plurality of curved surface portions. The plurality of curved surface portions connect adjacent flat surface portions to each other on an outer circumferential surface of the polyhedral drum. The flexible panel is disposed around the outer circumferential surface of the polyhedral drum. A top portion and a tail portion of the flexible panel may overlap each other on substantially the same flat surface portion of the polyhedral drum. The top portion and the tail portion correspond to respective ends of the flexible panel.
