P‐54: Contact Printing Technologies for Encapsulation of Flexible OLEDs

Contact printing is an encapsulation technique, which allows printing of UV-cured resin coated on a polymer stamp (polydimethylsiloxane, which is also known as PDMS) to different surfaces. The contact printing process allows encapsulation to be layered without using sophisticated methods and solvent effect [1]. In this paper, we present the fabrication of a new encapsulation for the flexible organic light-emitting diodes (OLESs) on a plastic substrate. Our experimental results confirmed that the encapsulation, which restricted the moisture that penetrated into the devices. This method is ideally suited to the fabrication of flexible OLEDs.
