Abstract

We fabricated an efficient top emission organic light emitting diode (FTEOLED) on paper substrates. For water proof and surface planarization, parylene of 5mm thick has been coated on copy paper substrate by vapor polymerization. As use this coating layer, fabrication of device was possible by photolithography and wet etching. Because paper is not transparent, we adapted top emission structure with transparent cathode and reflective anode. The FTOLED on paper showed the excellent electrical characteristic, $109cd/m^2$, 2.3cd/A at 10V.
