An electronic device can include an electrode and an organic active region. In one aspect, the electronic device can include the electrode having a corresponding pitch and an organic active region adjacent to the electrode, wherein the organic active region has a width greater than the corresponding pitch. In another aspect, an electronic device can include a first set of electrodes oriented substantially along a direction and a second set of electrodes oriented substantially along the direction. The electronic device can also include a space between the first and second sets of the electrodes. The electronic device can still further include an organic active region overlying or underlying the first and second sets of electrodes and the space. In other aspects, processes of forming the electronic devices are also disclosed.

Electronic device having electrodes and organic active regions and processes of forming the same

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.
