Abstract

One method to enhance the light out-coupling efficiency of organic light emitting diodes (OLEDs) by incorporating microlens arrays (MLAs) is demonstrated. The MLAs made of prepolymer NOA65 were fabricated on the substrate prepatterned by microcontact printing of hydrophobic self-assembled monolayers (SAMs). Due to the hydrophobic effect, the lens material was self-organized on the hydrophilic regions. After assembling the MLA onto the OLED, the optical measurement showed that the light out-coupling efficiency of an OLED with MLAs is improved without any apparent color-shift.
