Claim 17:
18. A method of driving a display device including: a first display area and a second display area, which operate at different frequencies in a multi-frequency mode, wherein the first display area includes a boundary area, which adjacent to the second display area, and a non-boundary area, which is not adjacent to the second display area; and a scan driver including a first scan circuit outputting a plurality of first scan signals and a second scan circuit outputting a plurality of second scan signals, the method comprising:
receiving a boundary image signal corresponding to a boundary area of the first display area, wherein the boundary area is a portion of the first display area adjacent to the second display area;
generating boundary compensation data by compensating for the boundary image signal; and
driving the first display area and the second display area based on a compensation image signal including the boundary compensation data,
wherein the second scan circuit includes:
a plurality of transmission circuits arranged to correspond to the non-boundary area, wherein the plurality of transmission circuits outputs a part of the plurality of second scan signals in the multi-frequency mode; and
a plurality of masking circuits arranged to correspond to the boundary area and the second display area, wherein the plurality of masking circuits masks a remaining part of the plurality of second scan signals in the multi-frequency mode.
