An electronic device includes a display panel, an input sensor, a panel driver, and a sensor controller. The panel driver drives the display panel at a first operating frequency in a first driving mode and drives the display panel at a second operating frequency lower than the first operating frequency in a second driving. The display panel displays the image in units of first driving frames in the first driving mode and displays the image in units of second driving frames in the second driving mode. The sensor controller transmits a first mode uplink signal to the input sensor in a first scheme in the first driving mode and transmits a second mode uplink signal to the input sensor in a second scheme different from the first scheme in the second driving mode.
