GE, Stanford, and MIT will team together to overcome the limitations in current technology by delivering to DOE a >75LPW illumination quality white light device (2800-6500 CCT, >85 CRI, >7000 hour life) that has a luminous output comparable to a 60W incandescent lamp (900 lumens). The proposed lighting systems feature optimized multiple color, high IQE OLEDs that are arranged on a common substrate. A synergistic combination of the light management film and OLED structure will form the basis of the Light Extraction Architexture (LEA). The OLED elements will be optimized using electrode texturing and “extra-fluorescence” to amplify the effect of the LEA. The OLED will be powered by a simple power supply that can be operated from standard line voltages and will require minimum additional luminaire structures, thus minimuzing driver and luminaire losses. When all technologies in this program are fully developed, the expected EQE entitlement will exceed 75%. As a result, a key roadblock to OLED technology development and commercialization for the lighting market will be removed.
