VITEX ANNOUNCES VOLUME PRODUCTION AND COMMERCIAL SHIPMENT OF POLYMER OLED
MICRODISPLAYS USING BARIX™ THIN-FILM ENCAPSULATION

SAN JOSE, Calif., Aug. 16, 2007
– Vitex Systems, Inc., a leading technology developer, licensor and
engineering service provider for thin-film encapsulation and moisture barrier films used in flexible electronic
products and displays, today announced that its customer and licensee, Microemissive Displays (AIM: MED.L) of
Edinburgh, Scotland, has commenced volume production and commercial shipment of its leading-edge polymer-
based OLED microdisplays. Today signals an important milestone for Vitex in its effort toward full-fledged
commercialization of OLED displays leveraging the company’s proprietary Barix™ thin-film encapsulation and
Barix resin system material.

John McEachran, director of operations for MED, noted “The thin-film encapsulation process technology
provided by Vitex has allowed our company to take full advantage of our unique Polymer OLED microdisplay
design. Our eyescreen™ product packs 76,800 pixels on a tiny, 6mm diagonal, silicon chip but delivers our
customers a superior viewing experience. We are pleased to be working with both Vitex and its partner, ANS.
The leading-edge encapsulation technology from Vitex and excellent support surrounding ANS’ production
equipment enabled us to meet our aggressive production ramp goals.”

The adoption of Vitex’s unique, extremely small (less than 0.5 mm) edge-seal process is one of the key features
allowing MED to achieve their leading-edge performance. “We are very pleased that Vitex and our equipment
partner and licensee, ANS of Korea, were able to work in close collaboration with MED—enabling them to ramp
their product into volume production, as scheduled” noted Chyi-Shan Suen, director of marketing for Vitex
Systems. He added, “We’re equally pleased in that today’s announcement marks a further step in our effort to
accelerate adoption of our leading thin-film encapsulation solution in the development of next-generation
displays and electronics products.”

The cooperation between Vitex and MED began last year. Earlier this year, ANS has established a full service
center in Dresden, Germany to service MED and other customers interested in pursing thin film encapsulation
for OLEDs, thin film solar cells and other organic electronics.
