The Canon-Toshiba project using so-called surface conduction electron-emitter display technology was hyped as replacing plasma and LCD televisions with crystal-clear pictures, offering deep blacks and better energy efficiency. The companies called it a "once-in-50-years historical turning point for the television industry."
Delay after delay doomed the pricey technology, as LCD and plasma set prices fell sharply in the interim. "It's something that has to be seen to be believed," a Canon marketing executive said in 2006. Sounds good. Too bad we never saw it.
