Official SED, Info, Discussion, Etc Thread!!! - Page 87  

The thing is, people have seen SED and have testified that SED is on a different planet. I have even heard the word "perfect" used to discribe SED.

Here are some comments made some who have seen SED:

''Toshiba is planning to release this new line of unbelievably accurate flat-panel sets in late 2006. The technology is called "Surface-conduction Electron-emitter Display" (yes, that's a mouthful) or SED for short. The electronics maker showcased prototype SED sets at CES and every IGN editor on-hand was in agreement: nothing else compares''.

"Toshiba reps are confident of SED, calling these sets the "new standard." And having seen them in motion, we agree. These babies are beautiful and nothing else that we've seen even comes close. "

MegaContrast was originally unveiled at CES 2006. Basically they managed to lower the 0 IRE light output somewhat combined with a sky high peak 100 IRE brightness to produce a 1 mil to 1 contrast ratio. In terms of real world viewing those who saw it felt it wasn't that groundbreaking, though any tech that improves LCD black levels should be applauded.

Going back to SED, I'm curious how many people will find the 30,000 hour life to be a sticking point. They'll have a hard time dancing around that figure in terms of marketing considering how many people pay attention to it these days. I also can't help but notice in the images posted recently that the large refresh "scan line" peopled noticed sweeping through the SED displays at the CES demos last year is still very evident on the current prototypes and is clearly visible in several of those shots.

This may have already been posted but CNET has some pictures of Toshiba's 55 inch upcoming SED display at CEATEC which supposedly will come out late next year(I know, I know...that probably means 3 years from now if ever). Here is the link and I hope it works...There are 2 or 3 pics of the SED display.

Question...What do you think the horizontal bar is from on the 8th picture? Maybe just the set reacting to the camera???

Pretty cool pics though

OOPS, I GUESS IT WAS POSTED.....but can someone help me with the above question?

The horizontal bar comes from the fact that SED draws the picture line by line, somewhat similar to how CRTs draw the picture. It's somewhat similar to how next gen LCD displays with scanning backlights will work.

You sure know how to put a damper on good news :(

For me, it's more of a hope that it's better and not being in a hurry to commit a lot of money to plasma or FP LCD at this point.

If nothing else, 1080p and HDMI 1.3 will be more refined in the next couple of years so even if SED doesn't pan out, the plasma and LCD products will be even better later on.

For now, I can make do with my 34 XBR for a couple of years. Unless PS3, Blu-Ray and other 1080p sources make HD Lite and even the best of Discovery HD or In HD material look so plain that it whets my appetite for a proper 1080p display.

But you really wonder if even the best 1080p plasma and LCD displays compare with a dated 1080i CRT. Yeah I'm sacrificing screen size but those other PQ parameters are more important to me.

In picture #3 (9 in the series), it can be noted that the area below the scanline is brighter than the area above. Unlike a CRT TV, the scanline moves UP the image, not down.

There is a scan line in the picture because it is a passive matrix display as Canon has hinted at in the past.

The scanning technique and the use of active- or passive-matrix are two entirely separate issues. Both AM and PM can be row-addressed, column-addressed, and updated in matrix-at-once, line-by-line or pixel-by-pixel fashion, depending on the chosen complexity, power consumption, etc. of the output circuitry.

Just like plasmas, PM was used - as expected. Active matrix means you have a transistor behind each pixel of the panel that acts as a switch. So only a power delivery grid and a single line for each transistor base need be routed out of the panel.

However, small transistors don't handle +80V switching very nicely, unlike LCDs where there's only a few volts. So all high-voltage displays will be passive-matrix.

That's true, I never thought of that. Also, SED is cathodoluminescence based which means it will need kilovolts to excite the phosphors (Canon claims ~12 kV). This also allows for very short emission times per frame which makes passive matrix possible. LCD is very slow and dim and thus required the development of active-matrix (sample and hold).

On the other side, passive matrix means some degree of flicker just like CRT's.

Not if you're willing to put craploads of expensive circuitry inside to address the entire grid at once. But that of course is outside their budget, which by now must be getting squeezed micron-thin by the cold shoulders of LCD and plasma competitors.

Plasma seems (visual observation) to update all pixels simultaneously, at least I haven't yet seen any scanlines on them. But perhaps their phosphor persistence is so long that it isn't visible.

The global strobe from both plasma and SED puts it out of the picture for me. I can't stand flicker of any kind. OLED is my big hope. Maybe the 2nd generation of SEDs will use faster refresh (85+ Hz.), but I doubt it due to circuit cost.

:) Honestly though I do hope SED makes it to market. I was an early adopter and spent 8K on a 42" ED panel and don't regret it one bit. The 3.5K I've since spent on my 50" will be easy to swallow if SED is released and does what they claim.

Didn't CRT reign for an awfully long time?

Yes indeed, but with the CRT design there were many significant improvements over time. If we were back in those days and AVS was around, each one of those improvements would have been looked at as a 'must have'. ;)

Yeah, like color. :D

Highly overrated--the ONLY thing that matters is inky blacks!! :D

I just wanted to post another picture from CEATEC Japan 2006 that I found while we wait. SED will be a household name very soon!! ;)

What I'm noticing is that the horizontal bar visible on the photos is smaller than it used to be. It seems to me that there must have been a change. Maybe they went from 60Hz to 120Hz? At least that's what they were planning according to my information.

It doesn't really matter dude, we are not gonna see anything anyway...the camera can see the bar, but we can't. Its no big deal.

The bar itself is no big deal. But there were reports of some people who were seeing a bit of flickering with the older prototypes. So if SED managed to go 120Hz now that would be good news.

120 would indeed be amazing, if they combined it with the ability to display 24, 30, and 60 fps material natively. No conversion schemes required - just display the same frame for numerous refresh cycles.

According to the next picture, it explains the line:

The lines on the sumo wrestler are caused by the way the camera interacts with the image on the screen. The lines are not visible to the naked eye.

Thank you for clearing that up. Can't wait for this technology :D

It doesn’t matter if we can’t see the flickering at 120Hz, it will still be there because that inherently the nature of CRT based devices (the only big flaw SED carries over from CRT). So people still might get headaches/eye strains from looking at SED. Luckily, I’m not one of those people :D.

The point is that many people see flickering with 60Hz but nobody sees it with 120Hz. If people get headaches/eye strain from SED/CRT, they may also get problems with pulasting plasma pixels and scanning LCD backlights, I guess.

My monitor shows the dude's pants as being a very bark blue and the ladies dress as being black.

Pictures don't do justice. When we see the black levels in real life, I assure you, the blacks will be inky, deep space blacks. When you turn the tv on without any picture at nighttime, you will not even realize that its on. The blacks will blend with the dark surroundings extremely well. It will be a sight to behold. Lets say you are watching the nighttime sky on the SED. You will see only the bright stars themselves. Everything around the stars will be pitch black. Of course, the colors will be amazing too! :D

Are you saying when I watch some like Star Trek and Star Wars space will finally black? :p

Our monitors are probably incapable of displaying the kind of black SED is capable of.
