Default SEDs or FEDs?

Carbon TVs to edge out liquid crystal, plasma?



You can find carbon in coal and tennis rackets, and a few years from now, it could run your TV. Various companies are currently trying to perfect the technology behind a new type of flat-panel display that will rely on diamonds or carbon nanotubes--two forms of pure carbon--to produce images.

Theoretically, these "field effect displays," or FEDs, will consume less energy than plasma or liquid crystal display (LCD) TVs, deliver a better picture and even cost less. The development of FEDs underscores the rapid changes taking place in what had been a relatively staid TV market.

Complete Story...

Thanks; hold on while I cancel my order for a Panny plasma .....

OK, I'm back (just kidding). Nice article though. It's funny that despite all these new types of sets with admittedly really nice features (plasma, LCD, LCoS, SED, FED, etc....) they almost always seem to mention a comparison to the good old fashioned CRT. Here's a quote from the article:
Quote:
"The concept of a nanotube TV will give you image quality similar to CRTs (cathode ray tubes), and the best image quality is still found on CRT TVs," said Tom Pitstick, vice president of marketing at Houston's Carbon Nanotechnologies. "All the major display manufacturers are looking at nanotube TVs."
I know DV CRT's are deep, heavy, and relatively small in viewing area, but there is no better compliment than when someone else tries to compare themselves to you. Rebuttals?

Agreed... you still see the comparison made over and over again in the press.

It's going to take something quite spectacular to pry those old Sony CRT projectors out of the magazine editors hands.

The technical comparison vs. CRTs is a valid one... all these techs use various methods to stimulate light emission from chemical phosphors with electron fields. The last (nearest viewer) layer is the same in all... an electrically stimulated phosphor coated on the back of the screen gives off light.

SED (surface emission display) is just a variant of FED (field emission display)... the field is generated by electrodes within a plane for SED... while many earlier designs had emitters perpendicular to the display surface. Different geometries generating the field. Plasma is related... Since all use phosphors, all can suffer burn in.

Comparison to CRT is common, even when the technologies are dissimilar... if only because CRT held 98% of the market in the previous generation, so all would be familiar with the baseline of the comparison.

And, yes, carbon is wonderful stuff... the major component of PEOPLE among other things...

May I ask what your major field of study has been, or can I guess that you have an extremely extensive background in chemistry? Or maybe physics? Whichever one it is, you obviously have at least a minor - or maybe a double major - in comedic studies.

Specialized in anything starting with a 'C'... carpentry, computers, chemistry, and on a good day cunilingus...
