Claim 19:
20. A method of driving a display device for driving a display panel included in the display device and including a plurality of pixels for a plurality of frames including at least one frame among the plurality of frames including a writing frame and at least one holding frame, a number of the at least one holding frame included in the at least one frame being adjusted depending on a driving frequency of the display panel, the method comprising:
applying a scan signal having an activation level to the plurality of pixels within a non-emission period of the writing frame;
applying an emission control signal having an activation level to the plurality of pixels within an emission period of the writing frame;
deactivating the scan signal in the at least one holding frame and applying the emission control signal to the plurality of pixels within an emission period of the at least one holding frame;
measuring emission current at the driving frequency with respect to selected sample pixels among the plurality of pixels;
modulating image data by a deviation between a measured emission current and a target current preset in response to the driving frequency, and generating a data signal based on modulated image data; and
applying the data signal to a corresponding pixel among the plurality of pixels within the non-emission period of the writing frame.
