Canon filed two SED TV related patents on April 30.

Patent 20090108727

and:

Patent 20090111350

These patents cover “electron-emitting device, electron source, image display apparatus and manufacturing method of electron emitting device”.

This is welcome news after a long period of quiet for SED TV. I’ll keep my fingers crossed to see something at CES 2010.
