03-06-2006 UNIVERSAL DISPLAY CORPORATION AND MITSUBISHI CHEMICAL CORPORATION ANNOUNCE AGREEMENT TO COLLABORATE ON
INK JET PRINTABLE OLED MATERIALS DEVELOPMENT

Ewing, New Jersey and Tokoyo, Japan – Universal Display Corporation (NASDAQ: PANL), the Company that’s lighting the way in developing and commercializing OLED technology for flat panel displays, lighting and other opto-electronics, together with Mitsubishi Chemical Corporation and Mitsubishi Chemical Group Science and Technology Research Center, Inc. (Mitsubishi Chemical), one of the world’s leading chemical companies, announced today that they have entered into an agreement to collaborate on the development of materials for phosphorescent OLED displays that are processible through solution or “wet” processing methods, such as ink jet printing. Printable phosphorescent OLED technology is a promising approach for large-area OLED displays that combines the high efficiency of phosphorescent technology with the potential cost-effectiveness of ink jet printing. The market for large-area OLED displays is expected to see dramatic growth in the coming years. Both Universal Display and Mitsubishi Chemical are preparing to participate in that growth through efforts such as this. “Collaborating with a world-class chemical company like Mitsubishi Chemical allows us to share ideas and help each other reach the next level of innovation for OLED materials based on our PHOLED™ phosphorescent OLED technology and Mitsubishi Chemical’s expertise in OLED chemicals and ink formulation,” said Steven V. Abramson, President and Chief Operating Officer of Universal Display. “Mitsubishi Chemical’s commitment to printable phosphorescent OLEDs, which we call P2OLEDs™, indicates that ink jet printable PHOLED technology has real commercial potential. By working in concert on the development of next-generation P2OLED materials with Mitsubishi Chemical, we hope to accelerate this process.” “This collaboration agreement with a world leader in the innovative OLED technologies like Universal Display is a remarkable milestone in the development of printable OLED materials,” said Dr. Yoshimitsu Kobayashi, Chief Technology Officer of Mitsubishi Chemical Corporation and the President and Chief Executive Officer of Mitsubishi Chemical Group Science and Technology Research Center, Inc. “Developing new and improved materials for display industries is one of five research and development focuses for the mid-term management plan. Mitsubishi Chemical’s OLED technologies combined with Universal Display’s technologies will certainly realize the earlier achievement of our goal.” Universal Display’s proprietary PHOLED™ phosphorescent OLED technology offers up to four times higher efficiency than conventional OLED technology – a feature that is very important for today’s battery-operated cell phones and other portable devices, as well as for tomorrow’s large-area TVs and solid-state lighting products. Over the past few years, Universal Display has announced a series of record-breaking performance milestones for its red, green and blue vacuum-deposited PHOLED systems. Through internal efforts and programs such as this one, Universal Display is also developing PHOLED emitters and other OLED materials for use in printable OLED systems. Mitsubishi Chemical has been developing OLED technologies and has a world-class OLED technologies and materials. At the end of last year, Mitsubishi Chemical announced that it had built the highest-efficiency printable blue phosphorescent OLED. MCC will accelerate its development of printable red, green and blue phosphorescent materials through this agreement with Universal Display.
