Abstract

The present invention relates to an over current control device and an organic light emitting display device adopting a function of interrupting an over-current. To provide a over current control device and a OLED device using the same, which allow a fast and reliable detection of an over current, an over current control device for detecting an over current provided to an OLED is provided, comprising: an over-current identification unit (410) adapted to compare a driving voltage (EVDD) on a supply line for driving the OLED with a reference voltage (V_over) on a reference voltage line for identifying the over-current; an interruption unit (420) connected between the supply line supplying the driving voltage (EVDD) and the pixel including the OLED for interrupting the power supply if the over-current identification unit (410) recognizes an over-current flowing through the supply line.
