Organic lighting-emitting diodes (OLEDs) are an emerging technology for gen-eral illumination applications in indoor environments. To understand how OLEDs perform during many years of use in the field, their long-term behavior is studied through accelerated stress tests (ASTs) at mildly elevated tempera-tures (e.g., 35°C, 45°C) and in temperature and humidity environments (65°C and 90% relative humidity). The findings from the ASTs provide insights into the chemical and electrical changes that occur in OLED panels during aging and how these changes affect their efficacy (e.g., lumens/watt) and photopic maintenance (e.g., luminous flux, chromaticity). Although OLEDs have not reached the performance levels of many inorganic LED devices, they have achieved sufficient performance levels for many years of use in indoor lighting applications.
