An organic light emitting display includes a pixel unit including pixels coupled to scan lines and data lines, a DC-DC converter for transmitting a voltage level of at least one power source of a first power source and a second power source to provide the power source to the pixel unit, and a voltage controller for controlling a voltage level transition time of the DC-DC converter. A method of driving such an organic light emitting display may include converting an input voltage into a predetermined first voltage level of a driving power source, adjusting the first level voltage of the driving power source to a second level voltage, wherein the second level voltage reaches a steady state, and applying black data to a pixel unit during a time period when the first level voltage is being adjusted to the second level voltage.
