An organic light emitting display apparatus, comprising:

• first and second pixel regions on a display region;
• first and second scan lines respectively connected to the first and second pixel regions;
• and
• a gate driver to respectively output a first scan signal and a second scan signal to the first and second scan lines, wherein the first pixel region includes a first pixel circuit and a first organic light emitting diode (OLED), wherein
• the second pixel region includes a second pixel circuit and a second OLED, wherein each of the first and second pixel circuits includes a driving transistor, wherein
• an anode of the first OLED at least partially overlaps a gate of a driving transistor of the first pixel circuit, wherein
• an anode of the second OLED at least partially overlaps the gate of the driving transistor of the second pixel circuit, wherein
• the second pixel circuit is to output a driving current to the anode of the first OLED, wherein
• a voltage level of a gate of a driving transistor of the first pixel circuit is changed by a first variance according to a change in a voltage level of the anode of the first OLED at a scanning time by the second scan signal, wherein
• the voltage level of the gate of the driving transistor of the first pixel circuit is changed by a second variance according to the change in the voltage level of the anode of the first OLED at an emitting time of the first OLED controlled by an emission control signal, and wherein
• the second variance is at least partially compensated by the first variance.
