Abstract
An organic light emitting display device includes a display panel including an organic light emitting diode, a power supply including a DC-DC converter that generates a driving voltage for the organic light emitting diode and that provides the driving voltage to the display panel, the DC-DC converter including an inductor and a switch, and an over-current prevention unit that blocks supply of the driving voltage when a value of a current flowing through the inductor is greater than a reference value.
