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