Comments on: Carbon TVs to edge out liquid crystal, plasma?

If you've bought a plasma TV, you might get one-upped in two years, when TVs using new carbon technology arrive.

What about EMI from the FEDs?

With cheaper FED displays, we'll all be able to have a big, wall-
sized TV's hanging in every room, but doesn't a FED display
generate electromagnetic radiation just like a CRT? The lack of
which was one of the health-related reasons to dump your old
monitor and get a flat-panel display...

SO what is new?

The new FED TV screens will most likely not be any worse then to ld CRTs, I have not found a warning notice on them from the US Surgen General yet, and probanly never will. We should be more proactive in EMI and EMC to and from these new devices.

Primary source of EMF not the screen...

The primary source of the Electro Mangnetic Field in a CRT is not the electrons hitting the screen and causing the phosphors to emit light, it is the Electromagnets generating an osilating field to cause the beam from the electron gun to go back and forth, as well as up and down to paint the screen in the first place.

As the electron emitters in a FET Carbon diamond or nanotube screen is immediately behind the coating that gets illumiinated by the emitters, there is no need to move the beam of electrons those emitters are generating. As a result the EMF will be basicly non-existant.

As a side note, this is not all that different from a Plasma display today. In all likelyhood there will be a lower EMF field for FET screens than there is for a Plasma display.

What about EMI?

Chrichton's "State of Fear" provided several references of US Research indicating no evidence of a health risk (besides being and awful novel). More recent EU scientific research: (HPA (UK)4/04)http://www.osha.gov/SLTC/radiofrequencyradiation/healtheffects.html - further suggests no scientific evidence of a health risk from EMI - not even high power lines.
