Abstract

Efficient multilayered organic light-emitting diodes (OLEDs) were fabricated using contact printing. In order to overcome the mixing problem occurring between the organic layers during the solution processes, contact printing was utilized on a small molecule layer. Since this contact printing allows multilayer stacking without the damage caused by organic solvents, high-performance OLEDs could be fabricated with solution-based small molecules employing a low cost process. In this study, the performance of the multilayered OLEDs manufactured by the contact printing process is significantly enhanced than that found in spin-coated devices.
