Abstract
An electrode contact scheme based on the use of an organic LiF alloy is inv estigated. The performance of organic light emitting diodes (OLED) with thi s contact scheme in both heterojunction and bipolar transport/emitting laye r (BTEL) OLED structures are compared with their counterparts with LiF buff er layers. The organic LiF contact scheme improved device reliability of BT EL OLEDs by 32% to 92 500 h while adversely affecting device reliability of heterojunction OLEDs.
