Display device and method of driving the same

A method of driving a display device comprising:

• receiving input image data;
• determining whether the input image data corresponds to a moving image or a still image;
• driving a display panel at a first driving frequency when the input image data corresponds to the moving image;
• selecting one of a plurality of flicker lookup tables based on the first driving frequency and determining a second driving frequency based on the selected flicker lookup table when the input image data corresponds to the still image;
• and
• driving the display panel at the second driving frequency when the input image data corresponds to the still image.

A method of driving a display device comprising:

• receiving input image data;
• determining that the input image data corresponds to a still image;
• looking up an intermediary second driving frequency in a reference flicker lookup table according to a first driving frequency;
• looking up a conversion coefficient in a conversion coefficient lookup table according to the first driving frequency;
• determining a second driving frequency by multiplying the intermediary second driving frequency by the conversion coefficient;
• and
• driving a display panel at the second driving frequency.
