Abstract
Ink-jet printing (IJP) technology is a popular technology for desktop publishing. Since some of the conducting (or conjugated) organic molecules and polymers are solution processable, IJP becomes an ideal method for printing polymer/organic light-emitting diodes with high resolution. In this review article, we present the hybrid ink-jet printing technology (HIJP), which consists of an ink-jet printed layer in conjunction with another uniform spin-coated polymer layer, which serves as a buffer layer to seal the pin holes between the ink droplets. This HIJP technology has been successfully applied to the fabrication of polymer light-emitting logos, multicolor polymer/organic light-emitting diodes, and the built-in shadow mask for the cathode patterning for pixelated polymer LEDs.
