Flexible Organic Electroluminescent Displays with Optical Transparency Using Electrically Conducting Polymers

摘要

Flexible OELDs were fabricated by using highly conductive poly(3,4-ethylenedioxy thiophene): p-toluene sulfonate(PEDOT : PTS) nano-films, as electrode layers. These conductive PEDOT : PTS films have a high transparency up to 80%, and possess a very low sheet resistance of 100 Ω square{sup}(-1) at 160-nm thickness. We report on the fabrication and characterization of a OELD using a PEDOT : PTS for the electrodes and demonstrate its superior performance relative to that of a similar device using the a-ITO layer. The device has been demonstrated to exhibit light emission in green, brightness level up to 1800 cd/m{sup}2 at the 25 V.
