Claim 10:
11. A method for changing a refresh rate of a display device of an electronic device, the method comprising:
identifying whether at least one of a request for changing a refresh rate and a change of restriction in changing the refresh rate is made;
changing at least one of a first parameter, a second parameter, and a third parameter, in response to identifying that the at least one of the request for changing the refresh rate and the change of restriction in changing the refresh rate is made; and
applying a changed parameter of the first parameter, the second parameter, and the third parameter,
wherein the first parameter is a frequency of a first synchronization signal formed in a display driving circuit of the display device,
wherein the second parameter is an increment or a decrement of a blank area in frame information to substitute for a portion of an active video area, and
wherein the third parameter is a frequency of a second synchronization signal for rendering.
