***eMagin Awarded Patent to Increase OLED Flat Panel Display Life
and Brightness
(February 21)

eMagin Corporation, a provider of organic light emitting diode
(OLED)-on-silicon display technology, today announced that it has
been awarded a new patent for technology that can significantly
increase lifetime and luminance in OLED displays. eMagin stated
that the invention described in U.S. Patent No. 6,337,492 could
enable production of higher brightness OLED flat panel displays
with longer life for a given level of brightness.

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.

eMagin stated that 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. The OLED sandwich is potentially most useful in
manufacturing OLED displays that require operation at high
luminance levels, such as aircraft helmet-mounted displays 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. 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.
