Grammar

Why does the sentence "While a post-doctoral student at Stanford University, physicist Joseph Jacobson envisioned a multi-page book with content that could be changed at the push of a button and required little power to use." contain "while"? "While" what? Is there a reason for this? — Preceding unsigned comment added by 51.9.86.5 (talk) 20:47, 16 March 2020 (UTC)

"While [he was] a post-doctoral student at Stanford University", that's what. It's perfectly good English as it is, is that not your first language?

Nook color?

Why is the nook color mentioned in this article? It has an LCD display, not eInk. I would just remove it, but if someone can justify it somehow, please go ahead and do that now.

Bad Marketing

There is no reason why iLiad must occupy all of the pictures of the eInk article. Something more popular in market must be represented. —Preceding unsigned comment added by 87.238.84.64 (talk) 08:10, 22 July 2010 (UTC)

Poorly constructed sentences

The following two sentences from the article are woefully lacking:

In addition, the Samsung Alias 2 utilizes this technology as the display on the buttons change. The October 2008 issue of the North American edition of Esquire was the first magazine cover to integrate E Ink.

Their author knew what exactly they were trying to convey, however they're completely meaningless to a lay person. When introducing new technology, some background information has to be provided first to set the stage for the technical innovations being discussed; e.g.: does 'buttons change' refer to a built-in display on the 'change-buttons', and what did the integration of E ink into or onto a paper magazine cover accomplish? Readers shouldn't have to start Googling word phrases to understand this type of basic information. Please revise as required -I don't even know were to start. HarryZilber (talk) 12:47, 23 August 2009 (UTC)

>does 'buttons change' refer to a built-in display on the 'change-buttons',

You'd imagine so, given the context. It mentions a changing display in an article about a changeable display.

>and what did the integration of E ink into or onto a paper magazine cover accomplish?

Hype, and the waste of about 7 or so watch batteries on each one. It was only on subscriber copies, not news stand, so I don't suppose it helped sell Esquire much, presumably E-ink, inc paid a fair amount of money for it, as well as supplying the parts. It wasn't really into or onto, more like a separate section of E-ink plastic stuck behind a paper cover that had cut-outs. There were maybe a dozen segments with some sort of countdown, one segment for each time period, not a numeric display. Since then the market for magazines with E-ink stuck on the front hasn't really taken off as well as you might have thought it did. Is it notable...? I have to say, no. It didn't portray information, just sort of flashed a bit, and was completely useless for any practical purpose. More landfill.

A proper use of E-ink in a magazine would be to display an article or even an ad, text or images. This couldn't do that, it was just pre-defined sections that could turn on or off. Second only in hideous wastefulness to that magazine that stuck an entire mobile phone (without it's case) with an entire colour LCD screen and some buttons, into an ad inside it's pages. To display a bit of video and some tat about some company or other. Obviously the advertising affected me deeply. This was about the same era. You couldn't make calls from it as-is, but with a SIM and installing a proper keypad you could.

Should it be Combined with Electronic Paper?

I believe that this article should be combined with the much related article Electronic paper. Perhaps registered and experienced Wikipedia users can help decide in this. Thank you 193.188.105.20 (talk) 16:25, 1 February 2010 (UTC)

No, it should not be combined. "E Ink" is a specific trademarked product produced by the E Ink Corporation. Electronic Paper refers more or less to the technology.

What does it do?

This article did not tell me what the e ink did or how it was different from my computers letter ink. —Preceding unsigned comment added by 99.237.86.230 (talk) 19:55, 25 May 2010 (UTC)

Yes it does. The very first sentence tells you that it is a specific proprietary type of electronic paper. Go read about electronic paper if you want to know what it is.

Updating of product lineup

E ink now also makes a segmented EPD, coined "Surf". I feel this should be included right under Triton. Also Pearl does not have a specific statement regarding its monochrome nature, if possible update this too with a backup statement/spec from E ink. —Preceding unsigned comment added by 66.135.236.42 (talk) 20:20, 23 February 2011 (UTC)

The first picture is very wrong O.o

Can someone explain to me how they manage to reflect "black light" from the black E-ink particles? The light becoming "Whiter" when it hits the white ones is also a bit weird, as I doubt that a red beam would suddenly gain the rest of the spectrum :P

--Synethos (talk) 18:05, 23 July 2011 (UTC)

My impression was that the white particles reflect white light (or whatever the incident light is), while the black particles simply don't reflect anything at all (they absorb it). So in terms of the physics, it's the same as with normal paper. Jimw338 (talk) 17:49, 23 June 2017 (UTC)

E Ink vs. e-ink problem

I think there are a lot of misunderstand about e-ink, because some people looking for e-ink and found just E ink here. E ink is part of the bigger group what contain all of e-ink technologies. Infect the Gyricon is e-ink too. Maybe in this article should be make clear this different.

Here is a useful link: http://thefutureofthings.com/3081-the-future-of-electronic-paper

"... E-paper comprises two different parts: the first is electronic ink, sometimes referred to as the "frontplane"; and the second is the electronics required to generate the pattern of text and images on the e-ink page, called the "backplane".

Over the years, a number of methods for creating e-ink have been developed. The Gyricon e-ink developed in the 70s by Nick Sheridon at Xerox is based on a thin sheet of flexible plastic containing a layer of tiny plastic beads, each encapsulated in a little pocket of oil and thus able to freely rotate within the plastic sheet. Each hemisphere of a bead has a different color and a different electrical charge. When an electric field is applied by the backplane, the beads rotate, creating a two-colored pattern. This method of creating e-ink was dubbed bichromal frontplane. Originally, bichromal frontplane had a number of limitations, including relatively low brightness and resolution and a lack of color. Although these issues are still being tackled, other forms of e-ink, with improved properties compared to the original Gyricon, have been developed over the years.

One such technology is electrophoretic frontplane, developed by the E Ink Corporation. Electrophoretic frontplane consists of millions of tiny microcapsules..." --Szente (talk) 00:38, 26 October 2011 (UTC)

Regal technology

Is the Regal / Regal 2 technology missing after the subsection 'E Ink Carta' ? I think it's being used in current generation (2016) readers, along with i.MX 7. 46.132.191.249 (talk) 13:08, 6 June 2016 (UTC)

All E Ink Carta displays support Regal waveforms, which reduces the need for page refreshes. This has been added to that section since it is a technology used in Carta, not a separate generation. Also, i.MX 7 is a Freescale chipset used in e-readers, which has little to do with E Ink. --Frmorrison (talk) 15:46, 7 June 2016 (UTC)

E-Ink Triton - physical description?

Has it been revealed how the Triton color display works? I would imagine it would have three layers (RGB) of translucent beads (reflective or not of it's specific color, clear to everything else), each sandwiched between it's own set of electrodes, and then have some sort of (bordering on hand-waving Star-Trek-Babble here I know) "stabilizing field generation" that would keep the one layer's electrodes from interfering with the other layers when it is changed. But is there anything known (in the patents?) Jimw338 (talk) 17:56, 23 June 2017 (UTC)

How the fuck does it work?

Besides a picture with no explanation, and what can be vaguely inferred by the History section, there's no explanation of how the current technology actually works Teo8976 (talk) 13:35, 19 January 2018 (UTC)

Yup. WTF is a microcup? And how can there be several differently coloured capsules in each cell, for the colour ones? How do the driver electronics distinguish between them, for which it wants to move? They're all in the same cell, no layering. They have different intensity levels (16 per colour) so if that uses different voltages for different intensities, what is used to distinguish between colours? E-ink's site doesn't seem to proudly mention it. Any other sources? Any academic or patent publications? This article serves better as an advertisement than an explanation at the moment, tells you what E-ink want you to know, and no more.

[10 minutes later...] Here we are! https://www.makeuseof.com/tag/dont-buy-e-reader-upcoming-technologies-kill-kindle/ reckons it uses a CFA, a colour filter array. A CMYK one, I think I read somewhere else. But the point is, just a load of colour filters, like LCD uses, or indeed colour cameras. It's a giveaway that the display has 300 DPI in monochrome, but only 100 DPI in colour. How does it switch off the colour filter? I dunno but I read somewhere else that the filter itself is based on LCD. No, not encyclopaedic, if you want that you can look it up yourself. I'm happy to have my curiosity sated.

84.67.73.190 (talk) 21:04, 14 January 2021 (UTC)

Thank you for defining CFA. In the article this acronym just appears from nowhere without any supporting definition. Mrbooch (talk) 08:24, 4 July 2022 (UTC)

Merger proposal

I propose to merge E Ink into E Ink Corporation. I think that the content in the E Ink article can easily be integrated into the E Ink Corporation page explained in the context of the companies technology development, and the E Ink article is of a reasonable size that the merging of E Ink Corporation will not cause any problems as far as article size is concerned. Blabelle (talk) 18:19, 30 May 2019 (UTC)

E Ink (this page) is the main one with a lot of information. So the E Ink Corporation page could be merged into this one, but I think it is fine to have two articles. --Frmorrison (talk) 19:37, 30 May 2019 (UTC);

Would it be possible to merge E Ink Corporation page into the E Ink page. It would help when to consolidate the information and drive readers to a single source for reference materials. Would I need to request this ask in the E Ink Corporation talk page? Blabelle (talk)

Stupid revert

E Ink has released to manufacturers a new colour E-ink based display technology that is appearing in multiple products. I added a section on this new product to the list of products that E Ink produces it, with a reference to a primary source web page made permanent through use of the Internet Archive's Way back machone.

And some person has just gone and reverted it. I gave a primary source reference, a page at E Ink's web site, saved at the internet archive. There's no better kind of reference to the technology produced by E Ink Corportation, which is what this page covers.

People will be coming to wikipedia to find out about this new technology when products start shipping in a month or two. — Preceding unsigned comment added by Pmpdurrant (talk • contribs)

Then we'll no doubt have some material on it in a month or two when independent, reliable sources are available. Wikipedia is built on secondary sources, not primary. - MrOllie (talk) 13:39, 27 April 2020 (UTC)

"Policy: Unless restricted by another policy, primary sources that have been reputably published may be used in Wikipedia, but only with care, because it is easy to misuse them.[d] Any interpretation of primary source material requires a reliable secondary source for that interpretation. A primary source may be used on Wikipedia only to make straightforward, descriptive statements of facts that can be verified by any educated person with access to the primary source but without further, specialized knowledge. For example, an article about a novel may cite passages to describe the plot, but any interpretation needs a secondary source." — Preceding unsigned comment added by Pmpdurrant (talk • contribs) 13:44, 27 April 2020 (UTC)

Merger proposal 2

I suggest the E Ink Corporation page be merged here into E Ink. I cannot find any reliable sources that treat E Ink Corporation as a separate and distinct topic from E Ink. E Ink is E Ink Corporation's only product and the company is not known for anything else. The short E Ink Corporation page could easily be summarized here in a "Background" section. There is not nearly enough source material for E Ink Corporation to ever justify a separate page under WP:LENGTH. CDaignault1 (talk) 20:08, 13 October 2020 (UTC)

No opposition has been expressed; proposer should consider proceeding with a BOLD merger. GenQuest ^{"Talk to Me"} 18:52, 30 October 2020 (UTC)

Requested Changes

I work for E Ink. Several portions of this page have erroneous information that is either unsourced, or not supported by the given citation. Most of it has to do with product naming conventions. I've used bold and strikeouts here to show the specific changes I'm requesting to correct this. CDaignault1 (talk) 19:10, 16 December 2020 (UTC)

Add Corporation/Business Infobox?

There appears to be a long history of confusion between E Ink and Electronic paper, both on this page and the Electronic paper page. I propose that it may help clarify that E Ink is a business if there were an infobox about the E Ink Corporation on this article. Thoughts?

askewchan (talk) 21:43, 28 December 2021 (UTC)

Carta versions

I think it might be helpful to clarify the various versions and dates of the Carta displays. From what I can see from E Ink press releases and https://www.eink.com/e-ink-film.html, Carta (apparently renamed as Carta 1000) was released in 2013, and at some point there were subsequent Carta 1100 and Carta 1200 versions that have improved response times and contrast over Carta 1000. There is also a Carta 1250 film mentioned in a 2021 press release which may have higher contrast over Carta 1200. https://www.reddit.com/r/ereader/comments/r5rqac/how_do_you_find_real_information_about_cartae_ink/

E Ink do not mention "Carta HD" and it is possible that it just refers to 300dpi displays vs (non HD) 212dpi displays. — Preceding unsigned comment added by 86.14.38.24 (talk) 07:45, 1 December 2022 (UTC)
