  • Top-emission organic light-emitting devices with microlens arrays
    Patent number: 8373341
    Abstract: Embodiments of the invention can provide organic light-emitting devices (OLEDs) with enhanced outcoupling efficiency. Specific embodiments can enhance the outcoupling efficiency by more than four times. Embodiments of the invention incorporate microlens 5 arrays on the emitting surface of a top-emission OLED. Incorporation of microlens arrays on the emitting surface of a top-emission OLED can greatly enhance the outcoupling efficiency in OLEDs. With a microlens array attached to the emitting surface, much of, if not all, of the waveguiding modes can be extracted. The microlens array can be fabricated using the inkjet printing method or using other methods, including molding.
