Display device in which transmission signals are varyingly generated based on a synchronization signal

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 vertical synchronization signal for determining a period of the frame and a horizontal synchronization signal for determining a scan timing of the display panel;
• and
• a sensor controller configured to control driving of the input sensor,
• wherein the sensor controller receives the horizontal synchronization signal from the panel driver and outputs a plurality of transmission signals to the input sensor, and
• the plurality of transmission signals are varied based on the horizontal synchronization signal,
• 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 horizontal synchronization signal and the output point in time is varied.
