On a computer screen, this ratio might be 1000:1 or more. On the Kindle, it is 7:1 with the E-Ink display. This is a huge fundamental difference in potential contrast!
(For reference, newsprint has a contrast ratio of about 10:1 and a reflective LCD display is only about 5:1.) He is apparently wrong in his assessment of reflective LCD, or at least wrong in lumping them all together. The Jetbook's LCD has a rated contrast ratio of 12:1, which, if the rest of his article can be believed, is better than newsprint but way better than eInk, relatively speaking. (reference: https://wiki.mobileread.com/wiki/Reflective_LCD) |
Certainly, it was a bit unfair to toss the relatively new LCD that is being used in devices like the JetBook. The JetBook and M218 are a bit oddball compared to most general-purpose reflective LCDs. Then again, 7:1 isn't an absolute figure for e-ink either, nor is 10:1 for newsprint. However, I do agree it (perhaps inadvertently) paints reflective LCD tech to be inherently inferior, which most of us acknowledge isn't the case with newer tech like the JetBook.
