Abstract: A microlens array for a light emitting device is disclosed. The light emitting device includes a plurality of OLEDs, each OLED having a minimum planar dimension. The array includes a plurality of microlenses, each of which has a minimum planar dimension and a maximum planar dimension. The minimum planar dimensions of the microlenses are larger than the maximum wavelength of visible light emitted from the OLEDs. The maximum planar dimensions of the microlenses are smaller than the smallest minimum planar dimension of any of the OLEDs.
