Description

ELECTRONIC PEN AND PORTABLE ELECTRONIC DEVICE INCLUDING THE SAME Various embodiments of this document relate to an electronic pen for a portable electronic device. Portable electronic devices, such as smartphones, can support calling, content search, or content output functions based on various types of applications. In the process of providing these various functions, portable electronic devices can output screens corresponding to each function. Users may desire to use a larger screen when utilizing the aforementioned various functions. In general portable electronic devices, if the display device is to be expanded for screen display, the overall size of the electronic device must increase, which may result in reduced portability.
