1. A display device, comprising:
a display panel configured to display an image in units of a frame;
an input sensor disposed on the display panel, and configured to sense an external input;
a panel driver configured to control driving of the display panel in response to a synchronization signal; and
a sensor controller configured to control driving of the input sensor,
wherein the sensor controller receives the synchronization signal from the panel driver and outputs a plurality of transmission signals to the input sensor, and
the plurality of transmission signals are varyingly generated based on the synchronization signal,
wherein the plurality of transmission signals are output from the sensor controller at an output point in time, and
wherein a time interval between an activation start point in time of the synchronization signal and the output point in time is varied.
