OLED WITH COMPACT CONTACT DESIGN AND SELF-ALIGNED INSULATORS

摘要

OLEDs and techniques for fabricating OLEDs are provided, in which the OLED has a shortest lateral current path through an active region that is longer than the shortest lateral electric field line within the active region. Such configurations prevent “hot spots” in the OLED panel, leading to a more uniform emission by the panel.

主权项

1. An organic light emitting device comprising:
a substrate; a first electrical contact; a second electrical contact; and an active region electrically connecting the first electrical contact and the second electrical contact; wherein the shortest lateral current path through the active region is longer than the shortest lateral electric field line within the active region.
