Abstract: An organic light emitting display apparatus comprises an organic light emitting display panel including a plurality of pixels each including an emission transistor that controls a timing in which an organic light emitting diode emits light; a gate driver outputting gate pulses to a plurality of gate lines provided in the organic light emitting display panel; an emission driver provided in the organic light emitting display panel and outputting an emission signal that controls turn-on and turn-off of the emission transistor to an emission line connected to the emission transistor; a data driver outputting data voltages to a plurality of data lines provided in the organic light emitting display panel; and a controller supplying a first signal and a second signal to the emission driver through one transfer line, wherein the first signal is generated for driving the emission driver when each frame starts, and the second signal is generated for driving the emission driver and has a period shorter than one frame period, and wherein the emission driver generates the emission signal through an emission start signal transferred through the one transfer line.
