3D color longterm stable liquid crystal displays on way?
October 29, 2014 | 2:25 pm

liquid crystal displaysA research team from the Department of Electronic and Computer Engineering at Hong Kong University of Science and Technology has announced a technological development that could deliver "optically rewritable 3D liquid crystal displays" that do "not need any power to hold the image after being uploaded." In other words, they are pioneering a technology that can produce a color, 3D equivalent to epaper, with the same durability and low power consumption. The abstract focuses (sic.) mostly on the development of an auto-stereoscopic method of producing goggle-free 3D images involving "holograms or the projection of the two images directly in to the...

The Inventor of E Ink Technology Nominated for European Inventor Award
April 25, 2013 | 12:15 pm

E InkI won't pretend to be familiar with the European Inventor Award myself, but according to the European Patent Office, "it pays tribute to the men and women whose quest for new ideas drives technological progress and economic growth, shapes society and improves our daily lives." Fifteen inventors are in the running for the award this year, and interestingly enough, one of the non-European inventors in the running is the U.S.-based team of Joseph M. Jacobson (pictured above) and Barrett Comiskey. Never heard of them? Me neither. But apparently they were the actual inventors of E Ink technology. E Ink displays, of course, have...

Thanks to Michigan researchers, e-readers and tablets are about to become much more colorful
February 10, 2013 | 4:22 pm

peacock feathers According to a February 6 article that appeared on, a website for "chief information officers and other IT leaders," researchers at the University of Michigan at Ann Arbor "have found a way to make colors more vivid on an e-reader screen, which could lead to the creation of advanced displays and spawn the development of color e-books." The scientific explanation behind the discovery is certainly complicated, but it has to do with something called structural color, "which is the foundation that makes things like a peacock's tail feathers appear iridescent," according to a separate article about the Michigan research team that...

New low-refresh screen may remove eyestrain from LCD
November 7, 2012 | 9:15 pm

thumb_230_1The LCD vs e-ink eyestrain debates have been going on for some time, but one factor in the difference is the refresh rate. E-ink sits still like paper once it’s set. It doesn’t refresh until you turn the page. LCD, on the other hand, refreshes dozens of times per second, whether it’s on a TV, a monitor, or a tablet. But that could be about to change. Nikkei Electronics’s “Tech-On!” reports on a new LCD display panel technology under development that will reduce the necessary refresh rate from 60 per second to 1 per second or less when showing...

Is Amazon planning a two-faced Android tablet?
July 11, 2011 | 2:15 pm

I’m not sure if I buy this, but Dave Zatz of “Zatz Not Funny” is reporting a rumor that suggests Amazon’s upcoming Android tablet could have a very interesting, idiosyncratic screen display format. According to a friend of Zatz’s who was seated on a flight next to someone who claimed to be a highly-placed Amazon exec, the tablet will feature both a color LCD and an e-ink screen—but unlike the Nook and the Alex, these screens will not be on the same surface. Instead, they will be on opposite sides of the device, like the faces of a coin. ...

Amazon’s Android Tablet(s) later this year – more on the likely display
May 16, 2011 | 9:35 am

The images at the left are from the HYDIS website's "Outdoor Readability" pagefor examples of their AFFS technology's display qualities as compared with Trans-reflective TN and and Conventional TN outdoors. AFFS is HYDIS' signature TFT-LCD technology (thin-film-transistor liquid crystal displays). In 1998, FFS was patented by HYDIS and "exceeded conventional IPS (in-plane switching) technology by offering wider viewing angles and improved transmittance."  In 2003, FFS became Advanced FFS, "with a 180 degree viewing angle and authentic color." According to HYDIS, "The AFFS technology applied in VIEWIZ tablet applications ensures perfect readability in any environment, even under bright sunlight, and allows you to enjoy the entertainment longer with...

Patent application suggests Apple is developing a dual-mode LCD/e-ink display
April 8, 2011 | 10:22 pm

applepatentA recently-discovered Apple patent application offers an intriguing look at a possible future for the iPad (and perhaps iPhone/iPod touch as well). AppleInsider reports that Apple is looking at placing a translucent e-ink display between the LCD display and the touch-sensitive interface layer allowing for selective display of content by regions. E-books could be displayed in the ink format, while pictures and video could use the full-color LCD-screen. While a similar duality of purpose can be found in switchable displays like the Pixel Qi screens we’ve mentioned a few times, this Apple-patented system would go one better in...

Pandigital Novel takes second place in e-reader sales for 3Q2010
January 21, 2011 | 2:07 pm

Mashable has an article (citing an IDC study) about the 17 million iPad units shipped in 2010, but it also focuses on the number of e-book readers that were sold. In the e-book field, they peg the Kindle selling 1.14 million units in the third quarter of 2010, but instead of Barnes & Noble the Pandigital Novel takes second place with 440 thousand units, followed by the Nook in third at 420 thousand. I find myself more than a little suspicious of these numbers, however, given that I know Amazon doesn’t ever reveal how many units they sell, and...

Nook Color gets 4 1/2 stars from Mobile Tech Review
November 30, 2010 | 5:44 pm

nookcolor_mymag.jpgThat's 4 1/2 out of 5 in the review by Editor-in-Chief Lisa Gade. The Nook Color is a wonderful surprise. As a long time E-Ink bookworm, I didn't expect much from Barnes & Noble's LCD reader. But B&N has turned out one of the hottest consumer electronics items of 2010 and perhaps 2011. The Nook Color offers an excellent reading experience thanks to its retina-friendly IPS display with high pixel density and wide viewing angles. Reading on an LCD has never been this pleasant and my eyes are feeling good when reading in my usual 1 to 2 hour sessions. That...

CNet: LCD vs. e-ink: The eyestrain debate. Thoughts on the NookColor. PCW Top 5 Tech
November 1, 2010 | 9:39 am

eyestrain.jpg CNet's David Carnoy weighed in on the debate over whether or not e-book reading on LCD screen causes more eyestrain than when reading on an e-Ink screen.  For him, it doesn't matter, but he apparently understands that for other humans it can be a problem though he prefers to think that it's not due to the LCD screen that others have a problem. In my own case -- with a focus only on words one after another against a background that puts light right into my eyes, there's quite a difference. I (and others report the same) can read...

Mirasol displays delayed until 2011
October 4, 2010 | 7:15 am

mirasol2 Om Malik reports on GigaOm that Mirasol’s low-power, sunlight-readable displays, previously scheduled for launch in 2010, are now expected to come to market in early 2011. Gizmodo notes that this is also about when the new displays from Pixel Qi are going to come out. It will be interesting to see what the sudden availability of not one but two low-power sunlight-readable display options is going to do to the e-reader market. The current best solutions for color reading involve LCD, which is washed out by direct sunlight. Will new-display readers drive LCD readers’ prices down? Or will...

Reading ebooks: LCD vs. eInk
September 21, 2010 | 5:18 pm

crt.jpgThere is always a lot of discussion about which screen is better for reading ebooks: and LCD screen, which is often less expensive, or eInk-type screens, which are often more expensive. Interestingly, the arguments often revolve around eyestrain, but I’m not so sure that is the real separator. Today, editors rarely work on paper. We all almost always read and edit manuscripts on monitors. Some editors still cling to the older CRT (cathode ray tube) technology — I still remember trying to fit 3 CRT monitors on my desk — but nearly all have gone modern and use a LCD...
