Large white organic light-emitting diode lighting panelon metal foils
Large-area top-emitting PIN structure (highly p- and n- type doped transport layersfor electrons and holes and an undoped emitter layer)–organic light-emitting diode (OLED)on advanced metal foils were fabricated for lighting applications. ArcelorMittal has developeda new surface treatment on metal foils, suitable for roll-to-roll production and dedicated tolarge-area device integration. Both monochromatic and white devices are realized on advancedmetal foils. Power efficiencies at 1000 cd/m2 of >70 lm/W (green), moreover, power efficiencyof white devices of >22 lm/W are achieved. Furthermore, first large-area 60 × 60 cm whiteOLED sources on metal foils are presented.
