主权项 1. An organic light emitting display device comprising: an organic light emitting display panel that includes a first power line, a second power line, a third power line, a plurality of scan lines and a plurality of data lines; a first transistor connected among a first node to which a data voltage of the data line is supplied, a second node which a reference voltage of the second power line is supplied and the first power line; an organic light emitting diode connected between the second node and the third power line; a power supplier configured to apply the reference voltage to the second power line; and a controller configured to apply at least one control signal including a data enable signal to the power supplier, wherein the data enable signal includes a plurality of high levels and a plurality of low levels alternately arranged in each frame, a rising edge of a first high level and a falling edge of a last high level in each frame define a supply interval of the data enable signal, wherein the reference voltage is synchronized with the supply interval of the data enable signal and gradually decreases during the supply interval of the data enable signal, wherein the first transistor controls a current being applied to the organic light emitting diode according to a difference voltage between the data voltage and the reference voltage.
