• and
• a display device configured to display an image, based on the input image data and the control signal,
• wherein the display device comprises:
• a display panel including a sub-pixel connected to a first sub-gate line and a second sub-gate line;
• a gate driver configured to supply a first sub-gate signal through the first sub-gate line and a second sub-gate signal through the second sub-gate line to the sub-pixel during a display scan period;
• a voltage generator configured to provide an offset signal to the first sub-gate line during a self scan period in which supply of the second sub-gate signal is stopped;
• and
• a controller configured to control the display panel, the gate driver, and the voltage generator, based on the input image data and the control signal.
