ORGANIC LIGHT EMITTING DISPLAY AND MONITORING METHOD OF THE SAME

摘要

PURPOSE: An organic light emitting display and a monitoring method of the same are provided to improve lifespan and image quality of an organic electroluminescent display by performing aging based on the characteristics of a sub-pixel. CONSTITUTION: An organic electroluminescent display device comprises a substrate, a display unit(AA), a monitoring pixel unit(MP), a plurality of monitoring pad parts(MM), and a plurality of aging pad parts(AM). The display unit comprises a plurality of sub pixels. The monitoring pixel unit is commonly connected to an interconnection connected to one sub pixel. A plurality of monitoring pad parts is commonly connected to the interconnection. A plurality of aging pad parts supplies an aging signal to a plurality of sub pixels and the monitoring pixel unit.
