Abstract
An organic light-emitting diode (OLED) with an increased service life and a method of manufacturing the same are provided. The OLED is subjected to electromagnetic radiation with a spectrum that at least partially overlaps the absorption spectrum of an organic material layer of the OLED. As a result, the OLED has a longer service life, reduced decay in its initial brightness, and more saturated color than a conventional OLED.
