21.1: Ink Jet Printing of Passive‐Matrix Polymer Light Emitting Displays

Abstract

Abstract The requirement and characteristics for red, green and blue (RGB) electroluminescent polymers[1,2] suitable for fabricating monochrome and full‐color passive‐matrix polymer display[3] will be discussed. The controlled deposition of the light‐emitting polymers is accomplished through the use of high‐resolution ink jet printing[4,5], where the materials are first tested in devices prepared using spincoating techniques. The specifications for polymer materials, as well as the display design which must be taken into account to make a high‐resolution passive‐matrix display with low power consumption are presented.
