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.
An OLED device comprising;
An OLED device comprising, a first OLED pixel layer comprised of a first layer electrode, a second layer electrode disposed adjacent to the first electrode and defining a first layer gap there between, an OLED particulate wherein the OLED particulate comprises organic-layered particles, each organic-layered particle including a hole transport layer and an electron transport layer having a hetero-junction there between, and a carrier material disposed within said first layer gap and containing said OLED particulate, and at least one subsequent OLED pixel layer comprised of a first subsequent layer electrode, a second subsequent layer electrode disposed adjacent to the first subsequent layer electrode and defining a second layer gap there between, said OLED particulate, and the carrier material disposed within said second layer gap and containing said OLED particulate.
