Abstract
A method for fabricating organic light active devices using field-attractive Organic Light Active Material (“OLAM™”) microcapsules. The OLAM microcapsules are randomly dispersed within a monomer carrier fluid that is injected or otherwise disposed between two electrodes. The OLAM microcapsules may include additives that impart rheological properties, and other electrical, mechanical, optical and magnetic properties. The OLAM microcapsules form chains between the electrodes when an aligning field is applied. Holding the aligning field to keep the chains formed, the carrier fluid is cured and the OLAM microcapsule chains are locked into alignment between the electrodes. The problem of contamination of the OLAM material is the major factor limiting the display life span, and thus is a bar to commercial success. This fabrication method results in the corrosion sensitive OLAM material being protected by the microcapsule shell and the cured carrier, and the pixel alignment is automatic, since the OLAM microcapsule chains are formed only between the electrodes.
