Claim 16:
17. A method of driving a display device, the display device comprising a first area and a second area, the method comprising:
determining whether to perform multi-frequency driving based on image data;
determining a determined gray level range of a display brightness value corresponding to a brightness level of a display panel;
determining whether pixel data of the second area is within a preset gray level range, a driving frequency of the second area being lower than at least one of a predetermined frequency and a driving frequency of the first area;
determining a number of pixel data values within the preset gray level range;
determining whether a number of gray level pixel data values of frame data corresponding to the second area is greater than or equal to a preset number;
applying an adjustment voltage to a second initialization voltage in each of the second area and the first area when the number of the gray level pixel data values of the frame data corresponding to the second area is greater than or equal to the preset number;
selecting a selected section group among section groups based on a selected display brightness value; and
determining pixel data for which gray levels are to be adjusted among pixel data of frame data corresponding to the first area based on a selected gray level range, an adjustment decision value, and a gray level adjustment value that correspond to each of gray level sections included in the selected section group.
