OMG more tv tech in the form of FED (field emission display) from Sony!!!

''A joint venture led by Sony Corp. will take over a plant run by Pioneer Corp. in Kagoshima in late 2009 to begin mass-producing field emission display panels (FEDs), which excel in both picture quality and energy conservation. These "dream panels," long regarded as the next generation of technology after liquid crystal and OLED displays, are finally about to see the light of day!''

FEDS are a lot like cathode ray tubes, except they will be super thin and have all the benefits too, like deep blacks and zero motion.

They're easier to build at large sizes than OLED TVs, so first onto the consumer market will be 60-inch displays (at the level they can be more profitable obviously), with smaller sizes to follow.

Cheers.

EDIT: just seen someone else posted a thread previously about FED, oooops, but still, they didnt mention it was ''a lot like cathode ray tubes, except they will be super thin and have all the benefits too, like deep blacks and zero motion'' so there

lol, most of us already know SED and FED are based on CRT technology.

These hyped up articles about new technologies will mean nothing until there are actually products to compare , until then take it all with a pinch of salt.

FED's , just like OLED's currently have a lot of problems to sort out before they make viable products , and even then they have to take on the entrenched and established technologies to become economically viable.

I find it a remarkably naive tactic to point out a new tech like FED similarities with CRT , when the market has already ditched CRT's in favour of LCD and Plasma , no one wants CRT's anymore , why on earth would you point out the fact that FED's are like them ?

For the record , OLED is currently trying to overcome the short lifespan of its core materials , and FED's current shortcomings are the outgassing the emitters caused while hitting the phosphors , which degrade the high vacuum that the display needs ....see the following ,

Potential disadvantages

Although physically simple, actual operation of field emitters in a production device are anything but simple. Field emitters depend on high electric field strength to tear electrons from the surface. Instead of very high voltages, FEDs use very small radii – atomic lattice size – and element spacing for cathodes. This small size renders the cathodes susceptible to damage by ion impact. The ions are produced by the high voltages interacting with residual gas molecules inside the device. FEDs require high vacuum levels which are difficult to attain: the vacuum suitable for conventional CRTs and vacuum tubes is not sufficient for long term FED operation. Intense electron bombardment of the phosphor layer will also release gas during use.

I wouldnt get too excited about them yet , when they are on the shelves is the time to start discussing them .... and thats a long way away.

I said my comments were from an article I read today!

Obviously if Sony are making a big deal about it then they think ppl still want CRTs

I have a 42PX80 and its fab, though I did see Sonys OLED in London and its looked amazing almost 3d, but it was a tiny screen 11inch I think.

Cheers.

Indeed Sony lost the plot with that particular gamble , their Wega CRT's were undeniably excellent and they didnt think people would switch so fast , which is why they were so late to the table with decent flatscreens and why they are very much still playing catchup.

It is most likely also the reason they are desperately looking at new techs to try and get an edge in the market.

why on earth would you point out the fact that FED's are like them ?

By the way when I said " you " in that particular quote I didnt mean it at yourself directly , I should have said " they" instead.

In many ways CRT televisions are far superior to lcd or plasma, if someone could produce a working tv with all the best qualities of a crt tv but in a flatscreen form and large sizes then that would appeal to many people.

In marketing terms though you are probably right, the general public might not understand why this would be a good feature as they think LCD and Plasma are a progression from CRT

I had a 28" Sony Trinitron for 10 yrs, its a gr8 tv, but I think my new 42PX80 is better!

hahaha no way

well on hd maybe, but for sd lcd and plasma SUCK

Sweeping statement and totally untrue , top of the range plasmas meet or exceed anything that was good about CRT's and eliminate everything that was bad , including that godawful flicker , I cannot watch a CRT now , I have one friend who still has to make the switch , he has a Sony Wega , and these days I cannot look at it for more than 10 minutes without getting a headache.

I'll grant you some budget flat panels are absolutely worthless , but most Panasonics tramp all over the primitive history that was CRT.

Both the existing mass market flat screen technologies already appeal to many people.

Anyhow, this forum is not the correct place for (yet another) discussion about how good, bad or indifferent LCDs and Plasmas are nor how they compare to CRTs.

All contributors please note - thanks.

Personally I think that companies just want consumers to buy anything that they invent regardless if its better or that the market wants it!

I am late to join the flat screen brigade, because I was so happy with my Sony CRT, but now I have changed my front room around and as I sit further away from the tv I needed a bigger screen, oh and I recently bought an Xbox 360 and its amazing playing games on my 42PX80!!

It will probably be 10 years before I upgrade again, regardless what 'new' tech is available

Cheers.

I for one don't think the market wants FEDs, but I know I do. They have amazing potential and I hope Sony really does get behind them. I'd buy one!

They don't.

Except the ones who have seen full HD CRTs.

LCDs or plasmas still cannot match a CRT when it comes to motion resolution during panning shots which is a very important thing and something that is very understated.

Hopefully a new technology like FED can offer as good performance with fast motion.

I think the market/demand for a new 2D display tech is shrinking rapidly. It wont be long before OLED and FED will have to show huge benefits to compete with dime-a-dozen LCDs.

Unless someone can figure out a way to use FED to make true, watchable, no-glasses-required 3D...
