Looks good, but some of the numbers are a little questionable, and I wonder where they get their proof of LCD eye strain. Overall it's a nice article though.

This is very similar to a basic summary of these kinds of display Nate wanted to put on the front page.

Probably from experience of the person who did the photos.

Different people react differently to LCD vs eInk, so I don't think such a comparison is possible. For example, I can't look at LCD screen in a dark room at all, instant headache - but I can look at it for hours if it's in bright lightbulb light. And I know a person who gets eye strain from CRT monitors, but none at all from LCD, even in darkness.

Yes, and old CRTs were pretty notorious at times. I myself used to get headaches reading from them. LCDs on the other hand, I have no problem whatsoever as long as ambient light is balanced with the backlight intensity, and I am exercising good reading habits (e.g. blinking regularly, not focusing too closely, &c.)

However, the article used the word "proven", which is a strong word to use in the absence of proof. If they're going to claim it is proven, it would be nice if they offered some details on the studies that provided said proof.

Generally I don't get eyestrain with LCD, probably because I use them at work all day and my eyes have adapted. My mother, on the other hand hates LCDs, says they give her headaches eventually.

These color devices look incredible, I really hope Kindle doesn't get left in the dust, but unless the K3 has mirasol, then they might be in trouble. Mainstream buyers will go for multi-use devices with video and other features that 'also' act as readers.

I typically don't have any problems reading on an LCD in low light or in situations or most indoor locations. Reading outside on an LCD is terrible, however, and this is where I can see these new technologies really shining.

While I thought it was a generally accepted idea that emmissive and backlit displays create more eye strain due to brightness and refresh rates, you're right to be asking for proof.

In a paper published on January 28, 2009 -- Measuring the degree of eyestrain caused by watching LCD and PDP devices -- four researchers created and tested a method that measured eye strain in individuals. Their findings were that both produce a large degree of eyestrain and that LCD devices produce a greater degree of eyestrain then PDP. The results were based on calculating the blink rate and pupil dilation of the subject, in a real time algorithm, while watching the displays.

Still, you're correct in stating that I shouldn't have used the word "proven" without quoting a reference. My apologies. I'm a firm believer that people producing web content should do so responsibly and be held to task if reckless.

Hope that you and the other MobileReaders enjoyed the article though.

Thanks a bunch. I've been looking for a few studies that established realistic links between emissive displays and eye fatigue or eye strain. Most such claims are just claims without any real evidence behind them, and many people are not especially sensitive to LCD viewing, myself included.

Also, Pixel Qi was saying their current screen's power consumption is about half a watt in reflective mode, while your article suggested 0.2 watts. Was that figure from Notion Ink, or from Pixel Qi?

Not a problem. Happy to help.

The 0.2W figure was quoted by SlashGear from Rohan Shravan (Notion Ink founder) at CES.

I have to wonder about the truth of their claims regarding the screen. I guess it makes the screen look better though...better than Pixel Qi said at least.

I wonder if Pixel Qi is perhaps including the display controller in their power usage claims?
