One million per square centimeter.

From that, I get sites spaced on a 10 micron grid. Then you can figure the redundancy in terms of emitters per pixel from that. I don't know enough to say whether this particular density means anything or not.

I'd be more impressed if the milestone weren't their own.
This statement looks self-contradictory to me:

"The result of the investigation of our carbon film technology by the reputable Lawrence Berkeley National Laboratory is significant in that it elevates our carbon film technology from laboratory status to an industrial process."
-- Dr. Zvi Yaniv, president and CEO of FEPET.

And does he mean to imply that it wasn't an industrial process before now? LBL is a respected lab, but if this really increases their licensing opportunities, they should license it and then issue a press release.

This stuff belongs in a government report, not in a press release, imo.

Thanks for the heads up Wills T. & L.

From the SIDT release:
>>"The result of the investigation of our carbon film technology by the reputable Lawrence Berkeley National Laboratory is significant in that it elevates our carbon film technology from laboratory status to an industrial process," said Dr. Zvi Yaniv, president and chief operating officer of FEPET. <<

I see the MBAs have gotten to Dr. Yaniv <g>.

I think that you sort of need demand for a product for an "industrial process".

Will L., my take on this announcement is that Will T. is right. The ability of these films to produce electrons is dependent on the material, not on geometry. Very sharp points help to expel electrons independent of the material. So if you use a material that has a propensity to expel electrons (i. e. has a low work function) then fashion it into very sharp points you get lots more electrons for a certain voltage to "light up" your phosphors. A colleague of mine went to work for a company that used to be called Silicon Video. He was very happy when they dropped the voltage they needed to expel sufficient electrons from 40 volts to 20 volts. I have no idea what the driving voltage is these days for field emission displays.

Will T., is there a physicist behind that curtain? <g>

WRT displays using the same tech as the LED lighting. I don't know if the display folks use the nitride LEDs but I would expect they will if they don't already. Will T. do you know how the active matrix folks get their green and blue?
