That's nice, but I can read whole books on an LCD with no light source - and have done so. So we're pretty much back to square one as to saying which technology will work.
LCD is just another surface being illuminated the same way the page of a book is.
Uhh.... LCD's are backlit, and in a dark room that strains the eyes. In what way is that at all similar to how one might light a book's pages?
Not at all, I get eyestrain on laptops if I can't make the screen bright enough. The iPhone (on which I have read books) can be brighter (but also auto-dims in low lighting situations), also generally when you are reading a book you are settling into a position that works for the long haul (or you are trapped in an airline seat).
These things dim to not strain your eyes as much, but this is a problem for you?
Again, eyestrain is all about lighting plus font plus font size.
If your idea of good lighting is staring into a bright light in a dark room, you are waaaaaaaaay off.
Go talk to an optometrist, don't take my word for it.. for the sake of your eyes man..
