Abstract
An organic light-emitting display device includes an organic light-emitting display panel having a plurality of subpixels connected to data lines and gate lines; a data driver driving the data lines; and a gate driver driving the gate lines, wherein the organic light-emitting display device has a first mode having a first refresh rate and a second mode having a second refresh rate that is lower than the first refresh rate, the second mode having a first period and a second period that is subsequent to the first period, and wherein, in the first period of the second mode, the data driver subsequently supplied data voltages to at least two of the plurality of subpixels, and in the second period of the second mode, the data driver supplies a specific voltage to the plurality of subpixels, the specific voltage being the same as one of at least two of the data voltages sequentially supplied to the at least two subpixels.
