  • Patent number: 6844128
    Abstract: 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.

  • Patent number: 6586153
    Abstract: 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.

  • Patent number: 6582876
    Abstract: 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.

  • Patent number: 6485884
    Abstract: 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.

  • Publication number: 20020158574
    Abstract: The present invention provides electronic displays and lamps that include a plurality of organic electroluminescent devices that emit polarized light. Displays can be made that include devices that emit the same or nearly the same polarization of light of different colors. For example, a full color pixilated display can be made that emits polarized light. Polarizing filters can be combined with such a display to reduce glare or increase display contrast without significantly reducing the intensity of the emitted light. Displays can also be made that include devices that emit different polarizations of light of the same or different colors. Tunable color of single color polarized light emitting lamps and backlights can also be made.
