Anyway, if I read books on LCD for more than 2 hours, my eyes do hurt, but I can read on a good e-ink device for 3 hours in a row without noticeable eye tiring. I am saying in general, it is true for most people that reading books on LCD hurts your eyes more than on an e-ink display (because of the reflective screen and the refresh rate), but your mileage may vary as some people find the page refresh behavior of e-ink more unbearable than the reflective screen on LCD. And it also depends on which particular e-ink or LCD display you are reading, I personally find Apple's LCD less strenuous on eyes than other brands LCD, and the nook pleases my eyes better than any other e-ink readers I tried. In the following thread, the lady said she could only read about 20 minutes each time because of the poor screen contrast of the ezreader pocketpro. https://www.mobileread.com/forums/showthread.php?t=84644 |
No, that's not how it works. You are misrepresenting the word "reflective". E-Ink is "reflective", as is the LCD in the Dr. Yi devices. They have no backlight, nothing that strobes, nothing that creates luminance disparity between the display and the surrounding environment. A reflective LCD is essentially the same thing as E-Ink (EPD) visually, with some minor differences (a bit better contrast with LCD, but slightly more limited in terms of viewing angle). You are thinking of an
emissive display, not a
reflective one.
There is
nothing about the LCD in a Dr. Yi device that would tire the eyes any more than an EPD like E-Ink. Excepting color cast and viewing angle disparities, it would be very, very difficult to tell the difference unless looking
extremely closely, where a reflective LCD should actually be superior at an equal resolution.
You make a fine point when you say the battery life is inferior. This is largely true. However, that you'd assume there to be eye discomfort or strain is simply ignorance of what an LCD actually is and how many different kinds there are.
