Title:Out-Coupling Efficiency Enhancement for OLED Lighting Applications by Enlarging Micro-Lens Array
Sheng-Jung Wu, Chun-Che Ma, and Hoang Yan Lin (Nat'l Taiwan Univ., Taiwan)
Abstract: The purpose of this study is to demonstrate a method to increase the out-coupling efficiency enhancement, and the illumination area. According to our simulations, we discovered that enlarging the size of micro-lens array can further enhance the out-coupling efficiency, as well as the illumination area. Moreover, with a single macro-lens, as large as expand the length of the substrate, the out-coupling efficiency enhancement ratio can be improved to 133.2%. There are different angular intensity profiles for different geometries of macro-lenses, which can be used for specific applications such as indoor lighting and local or focused illumination for reading. Besides, this method is practical because enlarging the size of micro-lens makes manufacturing easier.
