Abstract
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.
