Abstract
A method of providing a rollable display device includes providing 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.
Claims20
A method of providing a display device, comprising:
- providing a flexible display panel configured to produce an image;
- providing a tubular roller having an outer curved surface onto which the flexible display panel is selectively wound and unwound, and an inner surface defining a hollow interior space within the roller;
- providing a slit extending into the roller from the outer curved surface of the roller to the inner surface of the roller and extending longitudinally along the roller, the roller having no more than one slit extending longitudinally along the roller from a first end of the roller to a second end of the roller;
- providing a printed circuit board separate from the flexible display panel and located within the hollow interior space of the roller;
- providing a connecting unit disposed between the printed circuit board and the flexible display panel to connect the printed circuit board to the flexible display panel;
- and
- elevating a portion of the flexible display panel to unwind the flexible display panel from the roller.
