A method for fabricating organic light active devices using field-attractive Organic Light Active Material ("OLAM(TM)") 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. This pixel an-ay structure also greatly limits cross talk between pixels and the optical properties of the cured monomer can be controlled to improve contrast, display brightness, and display qualities. This OLAM fabrication method can be used for applications such as general lighting, display backlighting, video displays, digital maps, digital newspapers, stereoscopic vision aides, advanced vehicle windshields, solar cells, cameras, dynamic windows and photodetectors.
