This is exciting and will blow anything out of the water out there now in the lcd / plasma and conventional crt market. Imagine if some were constructed to fit arcade games!!. wooaaah. When these start rolling around the home market and price would permit lets start a petition for wells to do a run of 19" seds for our beloved games :).

check out some info here:

Its amazing that LCD's are going to be old tech so quickly.....thats great...I'll be picking up LCD's out of the garbage like I did when CRT's were put out during the upgrade era.!!!
 
I've heard my father-in-law mention this 'flat CRT' technology before, and how it will destroy plasma and lcd. Nice to see it is getting closer to reality.
 
Look at the date of the article.

Seems like the last thing I heard about this is that it is dead...no-one is working on it anymore. I don't remember why.

The latest and greatest for Flat Panels is organic LED I believe.
 
There was a horrible and long running patent dispute between Canon and Applied Nanotech Holdings over the licensing of SED, that didn't help the technology progress. Sony is supposed to have killed their version of the technology in favor of OLED.

One article I read literally years ago talked about manufacturing costs being astronomical, but early generations of technology often are, just look at OLED.

It would be nice to see is move forward if it's really as good as supposed to be.

Heh... I saw photomicrographs of surface emitters on the wall every day for 7+ years... never really went anywhere...

It's just like putting a a couple million tiny TVs on a substrate... can't imagine yields would be very good on a large-scale display.
 
Vaporware I'm guessing. I was exited about SED a few years ago, but I don't think it is going to happen (due mainly to the legal issues that Jrok mentioned).

They wouldn't be ideal for arcade machines anyway, because these things are digital displays, meaning they have a single native resolution like LCDs do. There is no way they would ever make 19" versions of these things with a 4:3 aspect ratio and a native resolution of say 288 x 224 to drop into a Pac-Man machine. In all likelihood, if they ever get made, they will have a 16:9 aspect ratio with a native resolution of 1920 x 1080. In other words, essentially useless for vintage arcade machines.

They would be great for movies and PC monitors though.

We'll never get a good replacement display technology for old arcade machines. Conventional 4:3 standard resolution spherical CRTs with a triad shadow mask are the only displays that look right in them.
