Abstract
Disclosed is to an over-current control device and an organic light emitting display device adopting a function of interrupting an over-current. To provide an 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 adapted to compare a driving voltage on a supply line for driving the OLED with a reference voltage on a reference voltage line for identifying the over-current; an interruption unit connected between the supply line supplying the driving voltage and the pixel including the OLED for interrupting the power supply if the over-current identification unit recognizes an over-current flowing through the supply line.
