Also check out 'Smart Glass Lab' webpage- they seem to be doing exciting research.

Interesting web pages that might be used to expand this article.

Merge & requested move
I have completely re-worked this article, incorporating also information from Smartglass except for the following aspects for which I could found no independent sources: "LC SmartGlass [...] uses about 5 W/m2 to run", and "The technology [...] is notably used extensively within the Guinness exhibition at St. James's Gate Brewery in Dublin".

Both stubs had so far quite incomplete information; the present contents of the article should give a much more complete overview over the topic.

I have also requested a move from "Smart windows" to "Smart glass", for the following reason:
 * "Smartglass" and "Smart windows" have been proposed for a merger. The new name should be a generic name, that is, "Smart glass", because "Smartglass" is corporate wording for a technology better known as "smart glass" (or "switchable glass"). Also, "Smart windows" refer exclusively to applications for windows, whereas the technology has a larger scope of applications. The present content of this page is a complete re-working of the topic, also incorporating the information from the the two stubs "Smartglass" and "Smart windows". The page Smart glass, to which the content of "Smart windows" should be moved, had a redirect to "Smartglass". — Chris Howard 20:45, 16 October 2006 (UTC)

I moved the page, as fairly uncontroversial. Smartglass which looked kinda spammish is now a redirect. I hope you merged the worthy contents here (frankly, I didn't check). Duja 07:23, 23 October 2006 (UTC)

Critical factor not explored
I noticed the introduction mentions "installation cost" as a critical factor, but the article never again mentions this factor. — Bikerbudmatt (talk) 14:16, 14 January 2010 (UTC)

"when" or "as long as" voltage is applied?
In the introduction, there's written “…which changes light transmission properties when voltage is applied.”. Does “when” mean “as long as” in this context or do you really just once have to apply voltage and it changes its color? If the former, IMO we should replace “when” with “as long as”. Thanks. --Mekeor (talk) 13:32, 14 April 2012 (UTC)

Is the film on this page really informative?

Power outage?
Just wondering which way it goes if the power goes out, does it turn clear or opaque? The article and the photo captions are confusing. — Preceding unsigned comment added by 114.198.96.49 (talk) 13:49, 27 January 2013 (UTC)

SPD section somewhat advertisement-like
Although the company is not mentioned directly, much of the material under Suspended Particle Devices is taken from marketing materials for Research Frontiers, Inc. of New York. In particular the claim of 30 different aircraft types is highly suspect, as it traces to a claim by a licensee that it had "installed or was currently engineering" (possibly meaning as little as determining specs for) windows with SPD on various aircraft models. In most of the 30+ cases there is little or no evidence that even one such window was created. Kpod (talk) 04:18, 12 April 2014 (UTC)

I tossed a couple of tags out on unsubstantiated claims in the automotive and aviation sections for this same reason. A lot of this does read like marketing copy and needs some detail. Isnoop (talk) 05:21, 20 December 2014 (UTC)

The table on Comparison of Smart Glass Technology is SPD advertising and not correct. For instance: line on Infinite Tint Variations. It states for SPD YES and for Liquid Crystal (LC) and electrochromic No. This is not correct. If you switch the LC with a simple voltage On (115V~) / Off this would be correct, but if you change the voltage gradually between 0 and 115V~ than you also have infinite tint variations with LC. Also in electrochromics you potentially can have infinite tint variations. For practical reasons, electrochromic products are sold with typically 4 or 5 tinting levels. In addition, also the entries for Blocks UV Rays at all Times and Protects Interiors from Fading are wrong: (the latter also means if there is UV protection or not). Usually, all LC products are laminated with laminating interlayers with UV absorbers. Therefore, they also block UV rays at all times and provide protection of interiors from fading. The same is true for electrochromics. They also have UV protection. Other statements in the table which favor SPD products are also wrong! — Preceding unsigned comment added by Saalebaer (talk • contribs) 12:01, 6 July 2016 (UTC)

Had the same impression for this section, but especially the mentioned image was bad. That showed a lot of untrue information and only served to make SPD look good. (UV protection doesn't even come from the smartglass technology...) I removed this, and added the advert message to the article. Dqeswn (talk) 09:18, 29 July 2016 (UTC)

Removing flowery, unreferenced content?
Smart glass#Examples of use in particular is bloated with unreferenced claims all with a subjective slant (WP:FLOWERY, WP:NOTADVERTISING). It includes seemingly random bits like: "A Hong Kong office uses 130 square meters of Privacy Glass, which is available in sizes up to 1,500 × 3,200 mm."

"The Boeing 787 Dreamliner features electrochromic windows which replace the pull down window shades on existing aircraft. NASA is looking into using electrochromics to manage the thermal environment experienced by the newly developed Orion and Altair space vehicles."

Would anyone bemoan me deleting that grab bag of unsourced examples? GS ⋙ ☎ 23:42, 12 February 2017 (UTC)
 * Being almost entirely unsourced, it mostly fails verifiability. It probably should disappear, but not instantly. I may be wrong about this, but protocol would seem to call for either a) waiting at least a few days, now that it's tagged, for sourcing to be added, or b) waiting at least a few days for talk page replies; then, with either a consensus or lack of response, it can go.

GPS and cell signals
Mention what kinds of glass might block GPS and cellular signals. Jidanni (talk) 10:57, 12 January 2023 (UTC)
