摘要: Provided are microlens arrays for use on the substrate of OLEDs to extract more light that is trapped in waveguided modes inside devices and methods manufacturing same. Light extraction with not limited emitting area, but also efficient extracting from whole patterned area where waveguiding occurs. Large array, compared size result over 100% enhancement. Such a array (O)LEDs specific emission, configuration, pixel size, or shape. It suitable all colors, including white, microcavity OLEDs, fabricated directly (modified) array.
