Abstract: A display device capable of setting an optimal output enable value according to a color pattern and a method for driving the display device. A timing controller is configured to receive an image signal from an external source, identify a color pattern and set an output enable value corresponding to the identified color pattern. A scan driver is configured to receive the output enable value and generate a first scan signal having a first turn-on signal and a second scan signal adjacent to the first scan signal and having a second turn-on signal. The scan driver may adjust an interval between the first turn-on signal and the second turn-on signal based on the output enable value.
