摘要： There is provided a process for making a multicolor organic light-emitting diode. The diode has a plurality of first subpixel areas (141) and a plurality of second subpixel areas (142). In the process, a patterned anode (110) is formed on a substrate and a non-patterned continuous hole injection layer (120) is formed over the anode. There is substantially no crosstalk observable between the first subpixels and the second subpixels. There is also provided the above process with the additional steps of forming a non-patterned continuous primer layer (130) over the hole injection layer, depositing a first electroluminescent material (141) from a first liquid composition in the first subpixel areas, depositing a second electroluminescent material (142) from a second liquid composition in the second subpixel areas, and depositing a cathode (160). The first and second electroluminescent materials emit light of different colors.

摘要： There is provided a process for forming an organic electronic device. The process includes the steps: forming a first layer, which includes an electrically conductive material and a fluorinated acid polymer, the first layer having a first surface energy; forming a second layer over the first layer, the second layer having a second surface energy which is greater than the first surface energy; removing selected portions of the second layer, resulting in uncovered areas of the first layer; forming a third layer over the uncovered areas of the first layer. There are also provided electronic devices made using the process.
