In one method of making an organic electroluminescent device, a transfer layer is solution coated on a donor substrate. The transfer layer includes an amorphous, non-polymeric, organic matrix with a light emitting material disposed in the matrix. The transfer layer is then selectively patterned on a receptor. Examples of patterning methods include laser thermal transfer or thermal head transfer. The method and associated materials can be used to form, for example, organic electroluminescent devices.

An electroluminescent device, and a method of making an electroluminescent device that includes one or more color conversion elements is disclosed. In one embodiment, the method includes forming an electroluminescent element on a substrate, where the electroluminescent element is capable of emitting light in a narrow band. The method further includes selectively thermally transferring a plurality of color conversion elements to the electroluminescent element. In another embodiment, the method includes forming an electroluminescent element on a substrate, where the electroluminescent element is capable of emitting UV light. The method further includes selectively thermally transferring a plurality of color conversion elements to the electroluminescent element.

Organic electronic devices having a conducting self-doped polymer buffer layer, particularly a self-doped polyaniline buffer layer, are described. Also described are organic light emitting diodes with buffer layers comprised of an intrinsically conducting polymer having no mobile counterions.

Organic electronic devices having conducting self-doped polymer buffer layers

Large area organic electronic devices having a doped conducting polymer buffer layer are described. Methods for applying a doped conducting polymer buffer layer to an electrode-coated large area substrate are described. The methods include web coating techniques such as microgravure coating or meniscus coating, which may be used in continuous coating processes.

A thermal transfer element for forming a multilayer device may include a substrate and a multicomponent transfer unit that, when transferred to a receptor, is configured and arranged to form a first operational layer and a second operational layer of a multilayer device. In at least some instances, the thermal transfer element also includes a light-to-heat conversion (LTHC) layer that can convert light energy to heat energy to transfer the multicomponent transfer unit. Transferring the multicomponent transfer unit to the receptor may include contacting a receptor with a thermal transfer element having a substrate and a multicomponent transfer unit. Then, the thermal transfer element is selectively heated to transfer the multicomponent transfer unit to the receptor according to a pattern to form at least first and second operational layers of a device. Often, when the thermal transfer element includes a LTHC layer between the substrate and the transfer layer, the thermal transfer element can be illuminated with light according to the pattern and the light energy is converted to heat energy to selectively heat the thermal transfer element.

Multilayer devices formed by multilayer thermal transfer

Disclosed are thermal transfer elements and processes for patterning solvent-coated layers and solvent-susceptible layers onto the same receptor substrate. These donor elements and methods are particularly suited for making organic electroluminescent devices and displays. The donor elements can include a substrate, an optional light-to-heat conversion layer, and a single or multicomponent transfer layer that can be imagewise transferred to a receptor to form an organic electroluminescent device, portions thereof, or components therefor. The methods offer advantages over conventional patterning techniques such as photolithography, and make it possible to fabricate new organic electroluminescent device constructions.

The present invention provides a method for pattering oriented materials to make organic electronic displays or devices. The method includes selective thermal transfer of an oriented electronically active or emissive material from a thermal transfer donor sheet to a receptor. The method can be used to make organic electroluminescent devices and displays that emit polarized light. The method can also be used to make organic electronic devices with enhanced charge mobility properties. The present invention also provides donor sheets for use with the method, and methods for making donor sheets that include transfer layers having oriented electronically active organic materials.
