Abstract: There is provided a new process for forming a light-emitting diode device having first, second, and third subpixel areas. In the process a hole injection layer is applied over an anode layer. The hole injection material has a conductive polymer and a fluorinated acid polymer. A hole transport layer is applied over the hole injection layer. A first electroluminescent material which is either green or blue, is applied to the first subpixel areas. A second electroluminescent material which is either blue or green, is applied to the second subpixel areas. A red electroluminescent material is applied overall, followed by deposition of a cathode. The second electroluminescent material emits a color different from that of the first electroluminescent material.

Abstract: There is provided a process for making a multicolor organic light-emitting diode. The diode has a plurality of first subpixel areas and a plurality of second subpixel areas. In the process, a patterned anode is formed on a substrate and a non-patterned continuous hole injection layer 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 over the hole injection layer, depositing a first electroluminescent material from a first liquid composition in the first subpixel areas, depositing a second electroluminescent material from a second liquid composition in the second subpixel areas, and depositing a cathode. The first and second electroluminescent materials emit light of different colors.

Abstract: 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.
