Talk:Surface-conduction electron-emitter display

message: This statement makes no sense to me: "The market for SEDs as monitors is unlikely, as SEDs have very poor picture quality outside of their native resolution."
How is that any different than LCD monitors? Doesn't the image quality of a non-native resolution for any fixed pixel technology have everything to do with the scaling/processing technology, and nothing to do with the display itself? And aren't LCD monitors exploding in the computer display market, even though they have this very problem?
:: How though? I thought they worked more like CRT... CRT does not have a problem with native/non-native resolutions. Why should SED? Surley it'd just be a mattter of setting the resolution for each of the emitters?
You (last poster) obviously haven't read about the working principles of the SEDs. SEDs have a separete electronic gun for every pixel/subpixel, meaning they have a native resolution just like LCDs. But, just like LCDs, they can be scaled to any resolution, with minor loss of image quality. Tani unit 01:40, 12 June 2006 (UTC)
replies: text: Electrons crossing a nano-gap at 10 volts probably won't give a great deal of stable control over the current. 8 bits = 256 levels of brightness per pixel is the usual standard. The control mechanism is Quantum tunnelling which is very non-linear so they may well use Pulse-width modulation.  --195.137.93.171 19:48, 2 December 2007 (UTC)

message: JR: One of the last sentences also says something about
light guns. I don't think the phosphor coating
has anything to do with the possibility of using
light guns in connection with the display.

message: This sentence is very confusing: "When the electrons cross electric poles across the thin slit, some are scattered at the receiving pole and are accelerated toward the display surface by a large voltage..."  --128.255.179.98 05:12, 24 July 2006 (UTC)

message: The "Technology" section says "The technology has been in development since 1987".
Just below this, the "History" section says "Canon began SED research in 1986".
Can anyone clear this up? I don't want to correct these to "in the late 1980's".Also, while I'm here, surely giving specifications for one demoed display as advantages for the whole technology is a little incongruous? The specs can stay, but generalisations about the whole technology can't be made on one display.

thread_title:  What year did Canon begin SED research? 

message: There was a drawback listed, "May be expensive when first released in 2007".  This seemed not unreasonable but speculative, so I replaced it with, "Pricing is unknown although, "Canon CEO Fujio Mitarai says he wants to offer the screens for about the same price as LCD and plasma TVs of comparable size."" which is more factual and informative.

thread_title:  Drawbacks 

message: Perhaps this is lacking in flow:
"Not enough information about technology. May be expensive when first released in 2007."
Maybe that should be elaborated on, as in "There is not much information available about this technology." And even with that statement, not much information about a technology is certainly not a disadvantage, in respect to a reason not to use it over other technologies. Maybe it is a disadvantage for wikipedians, but if waiting for new display technology and choosing something, if someone told me I shouldn't go for a technology because the public isn't in the know, I'd look at them funny.
There has to be info. out there, there is an article in the Nov 2006 issue of IEEE Spectrum making mention of details of this technology. 68.81.198.36 02:59, 4 November 2006 (UTC)
thread_title:  Bad grammar? 

message: The Nano-Proprietary Lawsuit section mentions carbon nanotubes. Does this display type use carbon nanotubes? Shouldn't that be stated in the description? Or somewhere? The Technology section, for example? 81.6.242.110 14:51, 19 July 2007 (UTC)
thread_title:  Carbon nanotubes 

message: " Modern SEDs add another step that greatly eases production. The pads are deposited with a much larger gap between them, as much as 50 nm "   : 50nm sounds like a mistake. More realistic would be 50um. Since I don't know this piece of data, I leave it uncorrected in the main text and just flag it here.  —Preceding unsigned comment added by 71.139.165.203 (talk) 04:50, 5 October 2009 (UTC)
thread_title:  Mistakes 

message: I don't like that the comparison section is so focused on the LCD display when the SED (and FED) display are more related to the Plasma display (PDP) that is not even mentioned in this section. It is difficult to comprehend the practical differences between Plasma and SED (such as color gamut, lifespan etc).  —Preceding unsigned comment added by 90.231.129.26 (talk) 13:38, 11 September 2010 (UTC)
thread_title:  LCD Comparison 

message: Please, the very first sentence of this article really needs to be reworked:
"A surface-conduction electron-emitter display (SED) is a display technology which has been developing various flat panel displays by a number of companies as a electronic visual displays."
The display technology has been developing displays? Technology can't create things by its self. How about this?
"A surface-conduction electron-emitter display (SED) is a display technology which has been developed as flat panel displays by a number of companies."
It's not great but it's better. ...I don't know how to sign this...  — Preceding unsigned comment added by 96.241.65.119 (talk) 14:38, 31 July 2012 (UTC)

message: the SED display technology could have been great, but current quantum dots or RGB backlight provide equivalent, if not better quality, making the business case for SED dead.  — Preceding unsigned comment added by 90.64.11.27 (talk) 11:19, 8 September 2020 (UTC)
replies: text: This isn't a book, there are not epilogues. Unless a direct connection can be assigned between the two technologies, such a remark would be baseless speculation. The conclusion is that SEDs are a technology that failed to emerge. 2601:540:C700:42DF:76C8:5F43:53F1:5C95 (talk) 21:23, 21 August 2023 (UTC)
