Display device

A display device comprising:

• a display panel which displays an image;
• a gate driving block which outputs a scan signal to the display panel;
• a source driving block which outputs a data signal to the display panel;
• and
• a controller which receives image signals and an external control signal and generates a gate driving signal, a source driving signal, and image data in response to the image signals and the external control signal, wherein the controller divides the display panel into a reference area operated at a reference frequency and a low-frequency area operated at a frequency lower than the reference frequency according to the image data and divides the low-frequency area into a first area operated at a first frequency lower than the reference frequency and a second area operated at a second frequency lower than the first frequency according to the image data, the source driving block outputs the data signal to the reference area at the reference frequency, outputs the data signal to the first area at the first frequency, and outputs the data signal to the second area at the second frequency, and the gate driving block outputs a reference scan signal to the reference area at the reference frequency, outputs a first scan signal to the first area at the first frequency, and outputs a second scan signal to the second area at the second frequency.
