Because I am on my computer all day, I would like something different for my eyes to focus on during my leisure reading time. But I do think part of this is generational: the kids who are growing up with ipads right now are going to find it "normal" to read that way, so they won't notice fatigue or attribute it to the ipad.
Considering the Lifehacker article was written last week, it would have been nice if they discussed front-lit e-ink readers (aka the Nook Glow) and whether those are easier or harder on your eyes. Instead they rehashed the same old same old. eP |

My eyes and head hurt after looking at an LCD screen for more than an hour or two (whether iPad, computer monitor, phone, whatever). I can read on my eInk Nook all day though with no problems.

This is interesting to me, but there's something I've always wondered at. I can read indefinitely on my K3. I sit at my computer for hours, but I'm constantly shifting from web site to web site, and refreshing the view to keep up with ongoing conversations. but I can only watch TV for an hour at a time or so, and it makes my eyes very tired. Movies in a theater are difficult for me, and lead to a headache. Is this a refresh issue? or just me being (as I so usually am) idiosyncratic?

Neither LCD nor eink bothers my eyes. I prefer to read on my Kindles as they are not nearly as heavy as my iPad, and the battery life is so much better. I like to save the battery on my iPad for watching Netflix, which drains it pretty quickly.

For me, the biggest drawback to LCD is the short battery life compared to eInk. If tablets refreshed even faster than 60Hz their battery life would be even shorter due to GPU and CPU load. I still do a lot of reading on my Nook though, because I can do so much more with it. I am still keeping a look out for a low power fast refresh color display like Mirasol in a reasonably priced e-reader.

I read two books on my tablet (long plane trip) and it was fine. I actually breathed a huge sigh of relief when I went back to my older ereader (non pearl). I have two pearl ereaders now which are even better.
I will definitely look at the iPad 3 because of the display, but doubt I will get one. Helen |

Refresh rate is kind of meaningless when talking about LCD. In a CRT, where the term originated, a beam of electrons scanned the screen horizontally from top to bottom, hitting phosphors which emmitted light. After the beam left a particular pixel, the phosphor was no longer excited () and the light decayed. The decay meant the display had to be refreshed, even if the picture shown was static, and this caused flicker. In an LCD, there is no phosphor to decay after an electron beam has hit it, therefore there is no reason to constantly refresh the screen. If an LCD pixel is turned on, it's state is maintained (either actively with a transistor or passively with a capacitor) until the data changes. No decay = no flicker (from the panel itself. Backlighting is another issue).
The refresh rate given for LCD TV is really a function of the controller speed and (more importantly) LCD response time. Yes, on televisons the screen is redrawn at the rated refresh rate, but that's because until recently TVs were fed a rather imprecise analog signal (the old joke was NTSC stood for: Never Twice the Same Colour ), not because they actually needed refreshing. Computer monitors were given analog signals as well (VGA), and did the same. Backlighting, however, can show a noticable flicker if it's the electro-fluorescent type. LEDs can also show a flicker if the brightness is regulated by pulse width rather than by voltage level. Which is better for your eyes? Ya got me, that's totally up to whichever you find more comfortable. |

Interesting video, but they appeared to have the iPad's brightness level artificially low for outdoor use.
That said, I still prefer eInk. |

If you have trouble reading on a LCD tablet or monitor try turning down your brightness. They are always too bright for me. On the monitor you can adjust the contrast as well. I keep my monitor turn down almost half way.
On a Android Tablet you can get an app called Screen Dim made by a member here that will allow you to adjust both. I have no problems using LCD as long as I turn down the brightness down to a comfortable level. I could never use my Kindle Fire without the Screen Dim app in the dark. Sure 2% is find in a lighted area but in the dark, no way. Of course everyone's eyes are different but this is what works for me. |

I usually read comments with a lot of interest, but today I want to put my five cents. I am passionate The New iPad 3 (had iPad 2, donated it to wife) user. I am doing somewhere around 180 (different) Keynote presentation per year (Job thing), and I watch 180 movies per year. And I cannot imagine myself leaving home without iPad. The only thing I cannot to use it for; is reading. It is ok to read web site or e-mail but if i need to read bunch of docs or book, I use Jetbook e-reader. This is rather strange but If I watch movies or preparing KNp, my eyes feel OK, if I start reading; within 25 min, I am getting “rabbit eye”.

There one thing that seam to be forgetten there. Screen size. On a larger screen , your eyes have to do more effort to do left - right again and again, as well as focusing.
But lcd can't beat e-ink in the sun. And the screen backgound not being pure white is more confortable. |
