ORGANIC LIGHT EMITTING DISPLAY DEVICE

摘要

PURPOSE: An organic electroluminescent display device is provided to add a simple driving circuit, which is able to apply a simultaneous scanning signal or a test signal, to a scan driving unit, thereby implementing a defect test and a simultaneous illumination of a pixel unit. CONSTITUTION: A pixel unit comprises a plurality of pixel which is formed at a cross region of a plurality of scan line and a plurality of data line. A first scan driving unit(110) consecutively applies a first test signal with a plurality of scan line, and detects the defect of pixel. A second scan driving unit(180) simultaneously applies a second test signal with a plurality of scan line, and detects the defect of pixel.
