Talk:Large-screen television technology

Problems

This new article needs the following fixes:

• Title case (only first word should be capitalized)
• Header case (same)
• References (wikipedia is never a suitable reference; it is not a source)
• Advantages/disadvantages lists are often subjective; to be suitable in wikipedia they must be from a reliable published source.

Laser Phosphor Display

I added the thech, but I'm not sure if its an adequate enough description. It also needs to be put into the advantage/disadvantage thing. I do hope that it's a good basis though Olekp (talk) 09:44, 27 June 2010 (UTC)

Viewing distances Table

The viewing distance table is wrong.

The text recommends a distance of "two to three times the screen size" but 3 times 15 inches is 1.14 meters not 1.5 meters and 3 times 26 inches is 2 meters not 2.5 meters.

All of them seems to be wrong. Also, the proper multiple to choose would be 2.5. ("One of the more popular recommendations on the proper HDTV viewing distance is multiply the diagonal measurement of the display screen by 2.5. This recommendation is cited by television manufacturers, retailers, respected publications")http://en.wikipedia.org/wiki/Optimum_HDTV_viewing_distance#The_Diagonal_Measurement_x_2.5

Most of the viewing distance recommentadions are wrong unless they give more detailed description for the reasons like viewing field, detail perception etc. For different resolutions and for differerent individuals those distances will vary. Article should mention that. Can someone mark this section as it needs to be fixed. 87.204.69.138 (talk) 09:16, 10 January 2012 (UTC)

OLED

Can someone add OLED technology to this article? Thanks -Halo 16:45, 13 May 2007 (UTC)

Sure, point me at a good source and I'll write it up. Dicklyon 20:31, 13 May 2007 (UTC)

Cheers. I've found a couple - [1], [2] and [3]. Hope that helps -Halo 20:56, 13 May 2007 (UTC)

Only the third one mentions large-screen applications of OLEDs, and just says a few companies have made prototypes. Is that enough to be worth mentioning here, or should we hold off and regard it as vapor-ware? Opinions? Dicklyon 21:07, 13 May 2007 (UTC)

power? shouldn't electricity use be in the advantages/disadvantages part? i searching for diffrence in power use now but it is hard to find

LCoS is another technology that needs to be added. http://en.wikipedia.org/wiki/Liquid_crystal_on_silicon

Update to reflect current situation

Re: "These technologies are quickly displacing cathode ray tubes (CRT) in the television space", I would contend that in mid-2007, CRT displays have all but disappeared from retail stores in most countries. Should the page be updated? Juux 00:03, 17 July 2007 (UTC)

I work at a retail store in Australia and currently we still sell a reasonable amount of CRT televisions. In fact, that is all that is on display. I agree that alternate technologies are being adopted now more than ever, but I do not agree that the CRT is dead, nor will it be for a while yet, especially when people want a cheap TV where a CRT's bulk is not an issue. --Greg Lockwood 20:12, 17 October 2007 (EST) —Preceding unsigned comment added by 220.239.238.178 (talk)

Power consumption?

An obvious improvement to the article would be something about the power requirements of the different technologies. I can't find appropriate like-for-like comparisons on the web, but I guess that the editors who've brought the page to its current quality are most likely to know the score here.

Possible Contradiction in LCD Section

Section 3.1.1 and Section 3.1.2 seem to contradict each other with the following lines:

From Section 3.1.1:

Does not suffer from glare in bright rooms

From Section 3.1.2:

Susceptible to reflection glare in bright rooms

Either the incorrect item should be removed, or the wording of one or both should be changed to avoid this apparent contradiction. --Greg Lockwood, 20:19, 17 October 2007 (EST)

== References ==http://en.wikipedia.org/w/index.php?title=Talk:Large-screen_television_technology&action=edit Editing Talk:Large-screen television technology - Wikipedia, the free encyclopedia

The current references are links to other Wikipedia articles - and going by the dates in the article, have been since March 2007! I'm surprised they have lasted in the article for this long - Wikipedia articles are not appropriate as references. -- Chuq (talk) 11:47, 21 November 2007 (UTC)

Laser Technology

At CES 2008, Mitsubishi showed off some prototype laser TVs. Mitsubishi was tight with the details at CES, but is there any more information?

A company that I had a very loose association with used a laser video projection system in the 1980's. It was based on two fairly powerful gas lasers, helium-neon for the red image and a krypton-argon for the green and blue. The lasers were scanned on the screen via a mechanical scanning assembly using prisms. The three laser coloured beams were individually modulated by a type of cell (name forgotten) but it did require quite a high voltage to provide full beam cutoff (several kilovolts). My recollection is that the entire projector was custom made (and may even have been 'home' made). 86.145.151.125 (talk) 11:46, 14 August 2011 (UTC)

Plasma's cooling details

Can anyone verify the "active cooling" with a "fan" statement for Plasma technology? I own a 2 year old set and it has no such noise nor cooling with a fan.

Ideal viewing distance

Can someone please post the ideal viewing distances for the various displays? I have heard of 3ft for every 1ft of viewing area (screen size). Thank you —Preceding unsigned comment added by 66.74.129.148 (talk) 17:07, 9 July 2009 (UTC)

Done. --IncidentFlux ^{[ TalkBack | Contributions ]} 18:34, 9 July 2009 (UTC)

LCD Television

The section on LCD Television has been tagged for lacking citations since 2009. There is no need for this lengthy discussion of LCD television tech here, because that subject has its own article. We can summarise that, and link to the main article. This article should concern itself primarily televisions with large screens.

The absence of citations makes it much more difficult for editors to verify the statements made, and opens the door for original research.

So I plan to reduce this section to a single paragraph (containing a link to LCD Television). MrDemeanour (talk) 11:33, 11 December 2018 (UTC)

pre-2000s (CRT era) situation is grossly misrepresented in this article...

the article, when discussing the days when all televisions were CRT, frankly, portrays an narrative of the past that is patently false.

far too much attention is given to the limitations of regular CRT televisions on their display size etc...at the time, this would have been a total nonsequiter on the subject of large screen television, because LARGE SCREEN TELEVISIONS AT THAT TIME WERE NOT SIMPLY GIANT SIZED CRT TELEVISIONS. the fact is, "regular" TVs DID have a size limit. but there WERE big screen TVs in existence back then! they were simply a DIFFERENT TYPE of configuration. these were the rear-projection TVs, that, from their coverage in this article, a reader born after the year 2000 would have absolutely no clue that before the 21st century, those WERE big screen tvs - all big screen tvs were of that design. Therefore, big screen tv DID exist, and THAT was what it was. and ABSOLUTELY NO regular typr CRT television was EVER used for this purpose, nor even conceived of, which the article seems to hint at that being the only possible solution in those days. Firejuggler86 (talk) 21:56, 18 February 2021 (UTC)

I have added a wikilink to rear-projection television in the lede. This article could do with a more structured history, and/or History of display technology could better cover the subject. If you have refs that support your view, or can pull them from either of these articles, feel free to add a referenced history section here that covers your concerns.Dialectric (talk) 02:04, 19 February 2021 (UTC)

Article needs updating to reflect OLED’s commercialization

Intro still refers to OLED as an in development technology:

“Various thin-screen technologies are being developed, but only liquid crystal display (LCD), plasma display (PDP) and Digital Light Processing (DLP) have been publicly released. Recent technologies like organic light-emitting diode (OLED) as well as not-yet-released technologies like surface-conduction electron-emitter display (SED) or field emission display (FED) are in development to replace earlier flat-screen technologies in picture quality.”

(Also Plasma is pretty much obsolete now, and I believe SED & FED technologies are now longer being developed).

Article as a whole is missing a section on OLED. Obviously this display tech has become commercially available in the last decade and within the last few years has finally become (relatively) affordable with TVs in the $1-2k range. 82.15.131.45 (talk) 00:03, 7 January 2023 (UTC)
