Claim:
1. A method of driving an organic light emitting display device, the method comprising: applying a respective one of a plurality of dummy-data signals, a respective one of a plurality of pre-data signals, and a respective one of a plurality of scan signals to each pixel of a plurality of pixels of the organic light emitting display device, respectively, from respective ones of scan lines and data lines of the organic light emitting display device during a non-emission period; and non-sequentially applying the scan signals and data signals to the pixels from the respective ones of the scan lines and the data lines during an emission period, wherein the data signals comprise data information corresponding to respective subfields in a unit time, wherein the pre-data signals are the same as subfield data at an end of the emission period, wherein each of the dummy-data signals corresponds to one of the pre-data signals, wherein each of the dummy-data signals is the same as subfield data of a different one of the scan lines, the different one of the scan lines being started, during the emission period, at a selection time before the subfield which corresponds to the corresponding one of the pre-data signals, and wherein the dummy-data signals are each applied at least one selection time before the corresponding one of the pre-data signals is applied.
