摘要： The invention provides methods for the production of full-color, subpixellated organic electroluminescent (EL) devices. Substrates used in the methods of the invention for production of EL devices comprise wells wherein the walls of the wells do not require surface treatment prior to deposition of electroluminescent material. Also provided are EL devices produced by the methods described herein.

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： Organic electronic devices may include an organic electronic component having an organic layer including guest material(s). One or more liquid compositions may be placed over a substantially solid organic layer. Each liquid composition can include guest material(s) and liquid medium (media). The liquid medium (media) may interact with the organic layer to form a solution, dispersion, emulsion, or suspension. The viscosity of the resulting solution, dispersion, emulsion, or suspension can be higher than the liquid composition to keep lateral migration of the guest material to a relatively low level. Still, most, if not all, the guest material(s) can migrate into the organic layer to locally change the electronic or electro-radiative characteristics of a region within the organic layer, with less than one order of magnitude difference in guest material concentration throughout the thickness of the organic layer. The process can be used for organic active layers, filter layers, and combinations thereof.
