1. A method of operating a sink device in which an organic light emitting diode included in a pixel circuit emits light in response to an emission on-off clock, the method comprising:
receiving an image frame;
changing a frame rate of a panel driving frame for a displaying operation according to a frame rate of the image frame; and
performing the displaying operation based on the image frame by applying the emission on-off clock to the panel driving frame,
wherein the frame rate of the image frame is changed while satisfying a condition in which an emission duty ratio of the panel driving frame is not changed.
