Abstract

A scrollable device including a fixture, a flexible display panel and a scroll device having a roller, a roller end cap and a torsion spring is provided. One side of the flexible display panel is connected to the fixture, while the other side is connected to the cylindrical surface of the roller. The roller end cap is rotatably disposed on the end part of the roller, and the torsion spring is inside the roller. One end of the torsion spring is connected to the roller, while the other end is connected to the roller end cap. When a relative rotation between the roller and the roller end cap is occurred, the torsion spring is rotated and deformed to form a restoring force. This restoring force can drive the roller to rotate relative to the roller end cap, thereby making the flexible display panel to roll up along the roller.
