Abstract: An alignment structure including a first casing, a first magnetic component, a second casing and a second magnetic component is provided. The first magnetic component is disposed at the first casing and has a first surface, and the first surface is a non-planar surface. The second magnetic component is disposed at the second casing and has a second surface, and the second surface is a non-planar surface. When the second casing leans against the first casing, the first surface and the second surface are facing each other, and a magnetic attraction between the first magnetic component and the second magnetic component guides the second magnetic component to be aligned to the first magnetic component, and stops the second casing from being separated from the first casing.

Abstract: A portable electronic device and a control method thereof are provided. The method is adapted to a portable electronic device including a rotatable element, a fixed element, a screen, a processor, a switch module with at least two protruding elements, and fixed points. The rotatable element is nearby the fixed element. The protruding elements and the fixed points are facing to each other and configured at one and the other of the rotatable element and the fixed element. The processor is coupled to the switch module and the screen. The method includes to display a default user interface corresponding to a default mode on the screen, to determine a corresponding mode according to all press states of each protruding element in the switch module by the processor when the rotatable element is rotated due to an external force applied thereto, and to display a corresponding user interface on the screen.

Abstract: A portable electronic device includes a first body and a second body. The second body includes a processing unit, and a first touch panel, a second touch panel, a keyboard and at least one detecting module electrically connected to the processing unit, respectively. The keyboard is slidably disposed above the second touch panel, and the detecting module is adapted to detect a position of the keyboard. When the keyboard is located at a first position, the keyboard module covers the second touch panel, and the detecting module transmits a first signal to the processing unit so that the first touch panel is turned on. When the keyboard is located at a second position, the keyboard exposes the second touch panel, and the detecting module transmits a second signal to the processing unit so that the first touch panel is turned off. A touch panel controlling method of the portable electronic device is further provided.

Abstract: A portable electronic device includes first body and second body pivoted to the first body. The first body includes casing, supporter, first magnetic component and torsion component. The casing includes accommodating trench and first trench. First lateral of the supporter is pivoted to the casing via the torsion component, and second lateral of the supporter includes notch. When the supporter is located in the accommodating trench and the first magnetic component extends into the notch, the supporter is positioned inside the accommodating trench by the first magnetic component, and the torsion component stores elastic potential energy. When the second body rotates close to the first body, the first magnetic component exits the notch due to magnetic repulsive force of second magnetic component of the second body, and the torsion component releases the elastic potential energy so that the second lateral of the supporter rotates out to support the second body.
