Motorola Labs has unveiled a colour video display prototype based on proprietary Carbon Nanotube (CNT) technology, a breakthrough technique that could create large, flat panel displays with superior quality, longer lifetimes and lower costs than current offerings.

Optimised for a 42in High Definition Television (HDTV) that is less than 1in thick, the prototype NED (Nano Emissive Display) 5-inch section uses CNTs to show how the design and fabrication of flat panel displays can be substantially changed.

NED technology is a scalable method of growing CNTs directly onto glass to enable an energy efficient design which excels at emitting electrons. The cost-effective process and design demonstrates the potential to create longer-lasting NED flat panel displays with high brightness and colour purity, said Motorola.

“With over 15 years experience and 160 patents in CNT and flat panel displays, we have developed a technology that could enable the next generation of large size flat panel displays to deliver an extraordinary visual experience at a fraction of current prices,” said Jim O’Connor, Motorola vice president of technology incubation and commercialisation.

“We now look forward to joining with display manufacturers and enabling them to further this technology and develop commercially available solutions,” he said.

Motorola’s proprietary CNT growth process provides precision in designing and manipulating a material at its molecular level to enhance specific characteristics, and, in the case of flat panel displays, producing high-definition images.

Motorola says the electron emission performance demonstrated by its technology exceeds that achieved to date with the application of the CNT to the cathode via an organic paste, the process used by other companies.

“Motorola has proven its NED technology to be fully video capable,” said Kimberly Allen, an analyst at iSuppli. “CNT direct growth on glass appears to have advantages over CNT paste/printing approaches and has potential for larger and more sophisticated displays.”
