Abstract

Official abstract text for this publication.

A top emission OLED includes a driving TFT including a channel region and source and drain electrodes. A power supply, a ground line, and a light emitting diode are electrically coupled to the TFT and an auxiliary electrode is electrically coupled to the ground line and to the source electrode of the driver transistor. The auxiliary electrode resides between the light emitting diode and the channel region of the driver transistor and is configured to shield the channel region of the driver transistor from an electric field generated by the light emitting diode.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for forming an organic light emitting device, the method comprising: forming a driving transistor including a gate electrode overlying a substrate, a semiconductor layer overlying the gate electrode and separated therefrom by a gate insulating layer, a source electrode and a drain electrode overlying the semiconductor layer and defining a channel region in the semiconductor layer; forming an insulating layer including at least one passivatio…
