Abstract
A flexible, rollable display system includes a display and one or more cover components coupled thereto. The cover components include openings that, when the display is wound around a roller, reduce induced stresses and the likelihood of the display cracking. The roller may include a flat portion to accommodate a printed circuit board or other electronic components less flexible than the display. The cover component(s) may be formed of heat radiating material(s) to improve performance of the system.
