Claim 17:
18. A method for driving a display device, the method comprising:
driving a first display region of a display panel at a first operating frequency during a multi-frequency mode, and driving a second display region adjacent to the first display region at a second operating frequency during the multi-frequency mode;
generating a first voltage in a first high voltage level and a second voltage in a first low voltage level, when the first display region is driven;
generating the first voltage in the first high voltage level and the second voltage in the first low voltage level, when a first horizontal line to an A-th horizontal line of pixels in the second display region are driven;
generating the first voltage in a second high voltage level and the second voltage in a second low voltage level, when an (A+1)-th horizontal line to an n-th horizontal line in the second display region are driven;
generating a scan signal based on the first voltage and the second voltage; and
providing the scan signal to the display panel,
wherein the ‘A’ is a positive integer and changes at every frame, ‘n’ is a positive integer, and A<n.
