The external input may include various types of inputs provided from the outside of the electronic device ED. For example, the external input may include not only an external input applied by contact with a part of the user's body (such as a hand), but also an external input applied close to the electronic device ED or adjacent to the electronic device ED at a predetermined distance (e.g., hovering). In addition, the external input may include various forms such as electricity, pressure, temperature, and light.
[0057] In an embodiment, the display surface IS of the electronic device ED may be divided into a transmission area TA and a frame area BZA. The transmission area TA may be an area in which an image IM is displayed. A user views the image IM through the transmission area TA. In an embodiment, the transmission area TA is illustrated as a quadrilateral shape with rounded corners.
