Paper Abstract

Organic light-emitting diode (OLED) materials were deposited directly on a concave glass surface using the electrospray deposition (ESD) technique to obtain three-dimensional (3D) multilayer OLEDs. Deposition without dissolving the underlying layer was realized by tuning the mixture ratio of the mixed solvents. A simulation of the electric force lines was used to assist in obtaining a uniform deposition on a 3D-curved substrate. The active layers of the OLED were sequentially prepared on watch glasses by the ESD technique. A green light emission from the concave device indicates that the ESD technique is a viable solution-processing technique for developing 3D multilayer OLEDs.
