HOPEWELL JUNCTION, N.Y.--(BUSINESS WIRE)--Feb. 21, 2002

eMagin Corporation (AMEX:EMA), the leader in organic light emitting diode (OLED)-on-silicon display technology, today announced that it has been awarded a new patent which can significantly increase lifetime and luminance in OLED displays.

The invention described in U.S. Patent No. 6,337,492 can enable production of higher brightness OLED flat panel displays with longer life for a given level of brightness, which can be used in future mobile information products such as wearable computers, electronic games, wireless Internet viewers, and mobile phones.

The invention, entitled "Serially-Connected Organic Light Emitting Diode Stack Having Conductors Sandwiching Each Light Emitting Layer," creates stacked organic light emitting devices driven by a current flowing uniformly through each of the stacked devices, or "sandwiches." Each device emits light so that the sandwich generates more light with the same current flow than would be generated by a single device.

Combining the new structure with eMagin's high temperature, long life, full visible color spectrum white OLED display technology has the potential to more than double lifetime or luminance in future mobile information products designed to take advantage of the invention. The OLED sandwich is potentially most useful in manufacturing OLED displays that require operation at high luminance levels, such as aircraft helmet-mounted displays (HMDs) and sunlight-readable displays, or in applications with frequent long-term fixed image patterns, such as instrument displays. This invention is adaptable to miniature optically-viewed microdisplays as well as larger direct-view displays.

In addition to key patents licensed from Eastman Kodak, eMagin now holds 64 patents in its portfolio with more than 70 additional U.S. patents pending. eMagin invented the award-winning SVGA and SVGA-3D OLED microdisplays, the world's first and only single-chip color video OLED microdisplay and embedded controller for advanced virtual imaging. According to DisplaySearch, a flat-panel display market research firm, the OLED display market is expected to grow to $2.5 billion worldwide by 2005.
