Rollable display device and electronic device including the same

An electronic device, comprising:

• a rollable display device including:
• a rollable structure including a plurality of unit structures, the rollable structure being rollable and unrollable based on the unit structures, and
• a display panel structure attached to the rollable structure,
• a rolling detection sensor to generate a rolling detection signal indicating whether the rollable display device is rolled or unrolled;
• and
• a processor to control a displaying operation of the rollable display device based on the rolling detection signal,
• wherein respective widths of the unit structures increase in a direction from a first side of the rollable structure to a second side of the rollable structure, the first side of the rollable structure being opposite to the second side of the rollable structure, and
• wherein each of the unit structures includes:
• a metal plate having a horizontal portion and an angled portion extending from a first edge of the horizontal portion, the angled portion being bent toward an upper surface of the horizontal portion by a bending limit angle, and
• a magnetic object attached to a second edge of the horizontal portion of the metal plate, the magnetic object being magnetically coupled to an angled portion of an adjacent metal plate.
