SED TV -2009 In Review

As far as SED TV goes, 2009 was an exceptionally slow year. I can’t believe it was 3 years ago I was packing my bags to go to CES 2007 only to have Canon pull the SED TV out at the last minute.

Any appearance of the Canon SED TV at CES 2010 would qualify as a miracle. The only news this year has been the issue of a couple of SED TV related patents by Canon and rumors that SED technology will emerge in the professional broadcast monitor field.

Who knows what 2020 will bring. OLED TV is still not quite there in the consumer market. FED TV production never got off the ground despite lots of promise.

Here’s a clip from the past…


Comments are always appreciated. Thanks to everyone for visiting the site, especially those long time readers and comment0rs who still have some hope for SED TV.

  1. thank you for keeping up this blog, i hope you will keep your eyes open for sed-news in future.


    SED vs. (HDi´s) Laser vs. OLED?

  2. This post feels like a little sad goodbye. I have followed this site for at least two years I think, and the SED technology generally since 2006.

    Of course I am still hoping that SED will reach the market in a few years, but the prospects are not looking good.

    If this is it (a bit like MJ), I would like to thank you all for the time around, hoping, speculating and all digging about a better future for TVs and monitors.

    A very special thanks to the one who runs this site, whose name is still shrouded after all this time. It has been a nice trip, I have appreciated it much, but it inevitably looks like we are not going any further for a while. Maybe not at all.

  3. i wouldnt pack it in just yet. as much as we would like this technology to be out there already for the general consumer we can hold hope in the fact that canon is seeking to produce a product for professional monitor displays. once it is out there even for this purpose people will realize and see the true value of what SED is all about.
    here’s hoping anyway.

  4. SED is the first item listed for Display Technologies at and in their web-book linked at the bottom of the page.

    I still hold the Sony Trinitron CRT as the standard. SED looks like a good competitor.

    Comments in the archive at make me wonder what the mean time before failure is for the various technologies. I know CRTs can last a long time (I have a Zenith TV from 1985.)

    Toshiba announced a 100,000 hour LED backlight and shorter lifetimes numbers have been noted previously .

    It seems that SED is simpler than trying to match LED resolution in the backlight to the LCD resolution in the display plane. I wonder what would be the lowest LCD/LED backlight resolution that would rival SED in quality, longevity, and whatever other factors are used for comparison.

  5. Thanks for all the comments. I started this site as an experiment and ended up getting very involved with SED TV technology.

    It very well may be a while before we ever see it but I’ll keep at this whenever anything interesting pops up.

  6. This is a nice site for updates on SED Tech.

    I would like to see SED TV occupying my living room one day. I hope they don’t abandon it after so many years of research.

  7. Well, we could stop buying anything else until they get the hint and start developing SED, nothing talks like $$$$, I for one will not be purchasing any new tv’s….LCD is disappointing and Plasmas is Plasma, would rather have my old Sony trinitorn back, and this is the year 2010 and the focus is on a failed form of entertainment from the 60’s, 3D, is anyone else laughing….
    Spend the cash is SED, and you will quickly forget 3D

  8. Just seen this article on PCWorld’s website about LPD TV’s.

    In it they compare this new technology to SED TV’s. It looks promising picture quality and energy efficiency wise but it may be a while before it’s seen commercially as it states that pro applications will be the first to get it. If Canon doesn’t get off of their butts and get SED TV’s out this could supplant it, which would be a shame as I want a SED TV.

  9. Until SED or something as good is ready for market, I will not part with CRT technology (except for computing applications). I recently bought a second-hand 36″ widescreen Philips CRT. It’s 8 years old but the picture quality is better than anything I’ve ever experienced. A very expensive set when first bought (AU$6000), it can do high definition 1080i at 60Hz, but I’m unable to use that because I live in Australia (a PAL country, ie. 50Hz), but it can do enhanced definition 576p at 50Hz which is how I feed the set at all times. I never knew how smooth a television picture could be until now. Like looking through a window.

    CRT is an example of a mature technology supplanted just when it reached the apex of its development. The same happened with vinyl records.

    I really hope SED succeeds.

  10. CRT isn’t really that good. You had to pay top dollar for FD-Trinitron and high grade parts, to minimize distortions, and maximize image clarity. If you didn’t have an FD-Trinitron with thin wires supporting the aperture grill; then you were stuck with a bleeding honeycomb shadowmask.

    If you spent enough money on the thing, you could hope that the electronics had enough “zones” to dial in your convergence. Even assuming you did dial it in, it only seemed to take a slight intensity change to shift the convergence off again never having it perfect, only “good enough”.

    Being a display critic, I always stuck with top dollar displays. Your comment suggests “other then computer monitors” – on the contrary, one of the only remaining reasons to even have a CRT is for high VGA to CRT sync rates (e.g. 160Hz refresh) with a unique display frame for each strobe.

    Modern TV’s (HDTV’s) **ONLY** have 72 / 120 / 240hz etc refresh rates to account for 3:2 pull-down, and simply repeat stagnant frames repetitiously.

    with the higher frequency’s often only used for marketing reasons. With perhaps a handful actually driving the first (new) strobe at a higher intensity to reduce display latency, but most do not do this.

    I could go on and on about why CRT has failed to offer better image quality, but some insist the down-rezed scan-lined screen looks “good” because of the artificial sharpening effect of LOW RESOLUTION.

    Some peoples brains just do a better job of filling in missing detail and thinking happy thoughts.

    i.e. purposely blurr your eyes while watching TV, and it may be perceived as more realistic.

  11. Before you consider me Anti CRT – The computer I’m accessing this site from has a 22″ Trinitron Display running at 1856×1392.

  12. TSoprano you no nothing about 3d tv with comments like that, go and enlighten yourself
    with a bit of research,

  13. Andy continues to try and impress everyone
    with his comments on crt and Sony trinitron,
    first off Andy you do not know even the
    basic construction of the trinitron, thin wires ARE the aperture grill, the shadow mask is a series of slots in a metal mask, a totally different method, as to the comments about people squinting there eyes, you really
    no nothing about the ability of the eye to
    resolve detail at a certain distance, are you one of the millions who have spent hundreds more for a full 1080p flat panel?
    now if your eye cannot resolve the distance from 8ft with a 50 inch screen between a HD thats 720p against a full HD thats 1080p
    then why would you waste more money on 1080p
    panels below 40 inches. have you Andy ever
    seen a crt showing HD on a size 32inch, I
    have and its visibly better than any LCD
    thats made so far, Andy if you don’t know
    about the trinitron, then you really have
    not got a leg to stand on!!

  14. yes your honour i will….knot (since you know the difference between no and know). i dont give a rats if 3D is good or bad but people are missing the whole point here. LCDs and plasmas have been bought en masse because they are the only viable option at the moment and prices are at rock bottom prices. if 3D tvs are promoted in a big way in the big markets then they will grab people as dumb as the ones that are buying LCDs and plasmas blindly thinking they have a better tv. i know it is all a gimmick but this is bad i think for SED because people will fall for this junk.

  15. You’re confusing the vertical thin mask “wires” (which are the aperture grill) with the horizontal stabilizing wire. So maybe YOU justice need to do some research.

    “You really do no nothing” – know*

    Have I spent hundreds more for a 1080p? I have no idea how much “more” I spent, but yes I do have a 1080p.

    “if your eye cannot resolve the distance from 8ft with a 50 inch screen”

    Do you mean: “If your eyes* cannot resolve the detail* from 8ft when viewing a 50″ screen” ???? Your grammar and syntax is terrible.

    “why would you waste money on 1080p”

    Why would you waste money on HD period? I don’t see it as a waste, my eyes are good enough to resolve the detail, and what does any of this have to do with CRT? Your way out Context here and your subject depth.

    Your final comment is rather fruitless and subjective.

    For one, LCD was never brought up, so why you are comparing CRT to LCD is beyond me.
    Secondly, a blanket statement that CRT is better then LCD is misleading and deceitful at best. What are you comparing? Obviously not geometric distortions, convergence, focus, resolution capabilities, interference rejection, and or a number of other traits in which LCD dominates the CRT.

    Oh Justice… Some peoples kids…. *sigh*

  16. TSoprano – For a viewer to see content in “3D” images need to simply be presented in stereo.

    SED could provide a “3D” experience via shutter glasses.

    A better approach however would be a screen (alone) that was able to present a unique image to both of your eyes. Such technology exists today, however it is very sensitive to viewer positioning and not at all effective for large audiences. (Think holographic baseball cards here.) The screen surface what can easiestly be described as “blinds” tuned to a specific angle of view. (e.g. perspective one’s blinds are pointed to the left, and perspective two’s blinds are pointed to the right.)

    The next best thing at this point requires glasses designed to filter or block the corresponding eye from the presented perspective. Polarizing light emissions from the set, and using polar filters offset for each eye is the most common method. LCD technology is better suited to this method, but it is still possible using phosphor based displays.

    I wouldn’t take TSoprano’s comments too seriously though, eventually if I correct him enough he will catch on and can go impress his friends with what he learns here.

  17. “I wouldn’t take TSoprano’s comments too seriously though, eventually if I correct him enough he will catch on and can go impress his friends with what he learns here.”

    ..i dont have to impress anyone andy, and i am dumbfounded at what comments i am not to be taken seriously enough by. all i said was that people (general public) wil be duped into buying 3D tv’s as a gimmick and the more crap thats out there and the longer time goes on with the falling prices of flat screens the harder i think it wil be for SED to enter the market.

  18. Sorry about that typo, I didn’t mean to write I wouldn’t take your comments too seriously, I meant “justice”‘s my bad.

  19. Does Au optronics make anything else then OEM panels without the bezels? I see they are in part of Acer displays. A quick search on ebay shows just the displays without any bids and bezels. Just displays you need to install on your pre existing laptop.

  20. If Panasonic can actually kill Phosphor trails with their new VT25 series i would consider myself very interested:

    “New phosphors and circuits allow the red and green phosphors to shorten their decay time by 66% preventing overlap of the left and right images (crosstalk), which is seen as ghost images.”—lc/996149

    “Because the 3D technology demands more from the plasma’s phosphors, Panasonic is introducing entirely new ones. With new red and green phosphors, the decay time has been cut significantly so phosphor lag should be a thing of the past.”

  21. Maybe they want stop only the production of Oled TVs.
    Aniway I bet that next PSP will have an oled screen.

    If Oled TVs are stopped, it mean that we can forgive all other borning display technologies… First of all SED and FED.

  22. Just picked up a old 19″ Triniton off ebay
    monitor brand new in the box condition.
    I had mine since 2001 just a matter of time before it gets dark and un-useable.
    Now I have to hunt for old pc parts like motherboards and graphics cards. I really would like to try out OLED but it’s probally going to be another two years or so for a under $1,000 PC monitor. Certin motherboards and chip sets and graphics cards have a negative effect on my eyes like nausea and eyestrain big time. LCDS are totally out of the question when it comes to my sensitive eyes.
