摘要:
The present invention provides a process for selectively thermally transferring insulators onto organic electroluminescent stacks or layers to electronically isolate adjacent devices upon deposition of electrode material. This can allow the formation of top electrodes for a plurality of organic electroluminescent devices on a substrate via one deposition step to form a single common top electrode or a plurality of electrodes patterned by shadowing due to the presence of the insulators.
摘要:
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.
摘要:
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.
摘要:
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.

A guest-host polarizer is disclosed that includes a host matrix, one or more first guest dyes disposed in the host matrix and oriented to absorb a first portion of visible light having a first polarization state, and one or more second guest dyes disposed in the host matrix and oriented to absorb a second portion of visible light having a second polarization state orthogonal to the first polarization state. Such guest-host polarizers can be used in various optical applications and display constructions.

摘要:
A thermal transfer donor element is provided which comprises a support, a light-to-heat conversion layer, an interlayer, and a thermal transfer layer. When the above donor element is brought into contact with a receptor and imagewise irradiated, an image is obtained which is free from contamination by the light-to-heat conversion layer. The construction and process of this invention is useful in making colored images including applications such as color proofs and color filter elements.

摘要:
A method for the manufacture of a matrix on a substrate, said matrix being particularly useful in the formation of color filter elements, the process comprising the steps of:a) providing an imageable article comprising a substrate having on at least one surface thereof a black layer,b) directing energy of sufficient intensity at said black layer to transparentize black layer,c) said directing of energy being done so that black layer is removed in some areas, but is not removed in other areas so that borders of black layer surround areas from which black layer has been removed.A preferred method deposits colorant material within the open areas of the matrix by thermal transfer, e.g., laser induced thermal transfer, of colorant material to form a filter element.
