1. An electronic device comprising:
a display panel configured to display an image;
an input sensor disposed on the display panel and comprising first electrodes, second electrodes electrically insulated from the first electrodes, and dummy electrodes electrically insulated from the first electrodes and the second electrodes; and
a sensor controller electrically connected to the input sensor, the sensor controller configured to drive the input sensor in a first driving mode or a second driving mode, wherein:
in the first driving mode, the sensor controller is configured to measure a variation of capacitance between the first electrodes and the second electrodes to generate location information of an input, and
in the second driving mode, the sensor controller is configured to use a first group among the dummy electrodes as a transmission sensing electrode and to use a second group among the dummy electrodes as a reception sensing electrode to analyze a body composition.
