An electronic device including a control unit, a display panel and a sensing unit is provided. The display panel displays an electronic book. The sensing unit is electrically connected to the control unit and the display panel. When the sensing unit senses that the electronic device is rotated around a first axis over a first angle, the control unit controls the display panel to display multiple pages of the electronic book instead of a content of the electronic book. The display panel also displays multiple annotations as the display panel is annotated.
