Abstract
An organic light emitting device (OLED) is disclosed for which the hole transporting layer, the electron transporting layer and/or the emissive layer, if separately present, is comprised of a non-polymeric material. A method for preparing such OLED's using vacuum deposition techniques is further disclosed.
Claims11
A method of fabricating an organic device, comprising:
- spooling a substrate having a first electrode disposed thereon from a first roll to a second roll;
- depositing a first organic layer over the first electrode while the substrate is spooling, the first organic layer comprising a non-polymeric organic material;
- depositing a second electrode over the first organic layer;
- wherein the first electrode comprises indium tin oxide, and wherein the indium tin oxide has a surface roughness that does not exceed about 3.6 mm.
