BTG Seeks Exclusive Licensee for a Fundamental Technology on Transparent Cathodes in Polymer OLED Devices.

WEST CONSHOHOCKEN, Pa. -- BTG (LSE: BGC), the intellectual property and technology commercialization company, today announced its plan to seek an exclusive licensee for a fundamental technology that uses transparent cathodes in polymer organic light emitting diode (OLED) devices. This fundamental technology includes US Patent 5,955,834 titled Light Emitting Devices Utilizing High Work Function Electrodes, and is one of a comprehensive portfolio of granted US patents and published applications licensed by BTG from The Ohio State University covering OLED technologies in the field of information displays.

BTG has established a dedicated team of OLED scientists to work on the commercial development of the patent portfolio in the state-of-the-art clean room facility and chemistry laboratory at the Ohio MicroMD Laboratory on the campus of The Ohio State University in Columbus, Ohio. Working with the development team are commercialization and patent executives in BTG's European and North American offices to build upon the existing patent portfolio and its exploitation.

Professor Arthur Epstein, Distinguished University Professor, Department of Physics and Chemistry, and principal inventor of the technology at The Ohio State University, continues to support the development activities through a consultancy role to BTG. BTG has invested a significant amount of its own development funding to demonstrate the technology for future polymer OLED product applications, to protect the intellectual property, and to commercialize the portfolio of patents, applications, prototypes, and know-how.

BTG now seeks to exclusively license this technology to one OLED manufacturing company, thereby giving them a competitive position in growing markets for polymer OLED products. Growing OLED markets enabled by this technology will use active matrix (AM) displays requiring transparent cathodes in either top emission or bottom emission (inverted) structures. The size of the AM displays can range from micro-displays, such as video camera viewfinders, to large sizes, such as polymer OLED televisions, which have recently been demonstrated through prototypes at various technology conferences in North America and Asia.
