1. An electronic device, comprising:
a display panel configured to display images;
an input sensor on the display panel and configured to operate in a first mode to detect a first input by an input device or a second mode to detect a second input different from the first input;
a panel driver configured to drive the display panel at a first operating frequency in a first driving mode and to drive the display panel at a second operating frequency lower than the first operating frequency in a second driving mode; and
a sensor controller configured to control driving of the input sensor,
wherein the display panel is configured to display the images in units of first driving frames in the first driving mode and displays the images in units of second driving frames in the second driving mode, and
wherein the sensor controller is configured to transmit a first mode uplink signal for synchronization with the input device to the input sensor in a first scheme in the first driving mode and to transmit a second mode uplink signal for synchronization with the input device to the input sensor in a second scheme different from the first scheme in the second driving mode,
wherein the second driving frames include a write frame and a holding frame, and
wherein the sensor controller is configured to divide a sensing area into a third area and a fourth area during the write frame, to apply a third uplink signal to the third area, and to apply a fourth uplink signal having a reverse phase with the third uplink signal to the fourth area,
the sensor controller is configured to apply a fifth uplink signal to an entire sensing area during the holding frame.
