34-inch colour inorganic EL display

iFire Technology has successfully scaled its flat panel display from 17 inches to 34 inches using its proprietary thick film dielectric technology.

iFire Technology, a subsidiary of The Westaim Corporation, has successfully scaled its flat panel display from 17 inches to 34 inches using its proprietary thick film dielectric technology (TDEL).

The 34-inch colour prototype display has a high definition television (HDTV) format of 1280 by 768 pixels and is claimed to be the largest flat panel ever produced using inorganic electroluminescent technology.

The 34-inch display has been fabricated using low-cost processes that are expected to be directly transferred to commercial production. The first several steps in the fabrication, referred to as the front-end process, were completed by iFire’s joint development partner, Dai Nippon Printing, at its primary production line in Kashiwa, Japan. The panels were then shipped to iFire’s facility in Toronto, Canada, where the remainder of the fabrication steps, referred to as the back-end processes, were completed, including the electronics assembly steps.

The first prototypes were made on a partially completed toolset using manual handling and operation. Over the next six months, iFire expects to complete the installation of the remaining prototype tools and focus on optimising processes to improve performance and reduce defects.

iFire expects to publicly unveil a full-colour 34-inch prototype at the 2004 Society for Information Display conference and technical symposium, to be held in Seattle, Washington between May 23-28.
