Abstract
An organic light emitting diode (OLED) display device and a method for aging the organic light emitting diode (OLED) display device. The OLED display device is constructed with an organic light emitting diode, a scan line for applying a scan signal, a data line for applying a data signal, a driving unit for applying the data signal in response to the scan signal, a driving transistor having a gate terminal electrically connected to the driving unit to supply a driving current to the organic light emitting diode in response to the data signal, and a first reverse bias transistor electrically connected between the gate terminal of the driving transistor and a first reverse bias voltage source. The method for aging the OLED display device includes: aging an organic light emitting diode, applying the same voltage to both of a first power supply voltage line, which is electrically connected to a first electrode of a driving transistor, and a second power supply voltage line, which is electrically connected to a second electrode of the organic light emitting diode, and applying a third reverse bias voltage to a gate terminal of the driving transistor.
