Abstract
A rollable display device includes a display panel for displaying an image, a printed circuit board connected to an edge of the display panel, and a roller which the display panel is rolled onto or unrolled from. The roller has a cylindrical shape having an inner space, and the printed circuit board is disposed in the inner space.
Claims19
A display device comprising:
- a flexible display panel;
- a roller on which the flexible display panel is selectively wound and unwound, the roller having:
- a curved surface having a first end and a second end;
- and
- a slit extending longitudinally along the curved surface of the roller, the slit being located between a first sidewall portion of the roller and a second sidewall portion of the roller, the second sidewall portion facing the first sidewall portion to define the slit therebetween, at least a portion of the roller extending continuously along the circumference of the roller from the first sidewall portion to the second sidewall portion with the slit therebetween, wherein the slit is the only slit extending longitudinally along the curved surface of the roller from the first end of the curved surface to the second end of the curved surface;
- and
- a printed circuit board connected to the flexible display panel, the printed circuit board being located within the roller.
