Classification: CPC G | IPC G

Claim 0:
1. An electronic device comprising:
a display device including a display driving circuit;
a processor operatively connected to the display device; and
a memory operatively connected to the processor, wherein the memory stores at least one instruction which, when executed, causes the processor to:
identify whether at least one of a request for changing a refresh rate and a change of restriction in changing the refresh rate is made;
change 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 the change of the refresh rate and the change of restriction in the change of the refresh rate is made; and
apply 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 the display driving circuit,
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.
