Abstract: A display device includes a display panel displaying an image using a gate signal and a data signal. The display device includes a gate driving circuit generating the gate signal using a gate control signal. The display device includes a data driving circuit generating the data signal using a data control signal and an image dataApplication. The display device includes a timing controlling circuit generating the gate control signal, the data control signal, and the image data using an image signal and a plurality of timing signals. The timing controlling circuit is further configured to transmit the gate control signal, the data control signal, and the image data with a variable refresh rate profile different based on a temperature.
