Abstract

In this paper, we have investigated the characteristics of polymer inkjet printing and fabricated OLED (organic light emitting diode) display using inkjet printing technology. To control the wetting condition of the droplet to the substrate, UV/ozone treatment technique is used. To make the repeated pixels on a substrate, precise vision alignment and multi-layer printing is used. With the successive printing of PEDOT/PSS as a hole injection layer and MEH-PPV as a light emitting layer, we have successfully fabricated an OLED and demonstrated basic working of OLED.
