***OLED Manufacturing Patent Issued for OVPD Technology
(January 22)

Universal Display Corporation, a developer of flat panel display
technology, announced today that its research partner, Princeton
University, has been issued a new patent for an Organic Vapor
Phase Deposition (OVPD) process for the manufacturing of Organic
Light Emitting Diode (OLED) flat panel displays. UDC has the
exclusive, world wide rights to this patent, titled "Low Pressure
Vapor Phase Deposition of Organic Thin Films," U.S. patent number
6,337,102.

UDC claims the advantages of OVPD technology include better
materials utilization, increased control over the deposition
process, higher potential throughput yield, and lower
manufacturing costs. OVPD technology also provides a significant
step toward Web-based continuous process fabrication for organic
electronics, including OLEDs, being uniformly and efficiently
deposited on thin, flexible surfaces.

Organic Vapor Phase Deposition involves the use of a carrier gas
stream in a hot-walled reactor at low pressure to precisely
deposit thin layers of organic electronic materials on to
displays. The research team believes the patented process
produces thin films with far superior surface properties, when
compared to traditional OLED processing.

Aixtron AG, a leading German equipment manufacturer, will
manufacture and sell OVPD equipment under exclusive license from
UDC. After an 18 month joint development program, the
preproduction OVPD fabrication equipment is currently being
installed in UDC's expanded pilot line facility.

UDC currently has exclusive rights to over 400 issued and pending
patents worldwide for Organic Light Emitting Devices (OLEDs).
These include approximately 200 patents from its seven-year
Strategic Research Partnership with Princeton University and the
University of Southern California as well as additional patents
it received from Motorola, Inc., in exchange for Motorola's
equity position in the Company. In addition to the OVPD patent,
they include patents in areas such as flexible OLEDs (FOLEDs),
high efficiency phosphorescent OLEDs (PHOLEDs) and transparent
OLEDs (TOLEDs).

Other recent patents provide exclusive worldwide rights for
fabrication and color tuning technologies for OLEDs. These
include:

Method for Patterning Devices, U.S. patent number 6,294,398,
issued September 25, 2001, relates to the patterning of OLED
devices over large areas in a Web-based manufacturing process by
stamping or cold-welding the electrodes.

Method for Deposition and Patterning of Organic Thin Film, U.S.
patent number 6,297,516, issued October 2, 2001, relates to
patterning small features in thin films using photolithographic
patterning prior to organic film deposition. This process avoids
exposing organic materials to photolithographic solvents that can
be harmful to OLEDs.

Color-Tunable Organic Light Emitting Devices, U.S. patent number
6,287,712, issued September 11, 2001, allows for tuning the
wavelength of light emitted by an OLED to achieve the desired
color, particularly in red OLEDs.
