Of course, half-tone illustrations are going to be pretty bad?it really should be 1200 for that. There is more to books than plaintext, you know.



    Well, OK, but the dpi on what most people associate with are common printers for the home. Most print though uses tricks to give a nice appearance.

    Not for a lot of them. For novels/non-fiction they are almost entirely text, which is what eink excels at.



    And isn't project Gutenberg all .epub format? Not fancy HTML.

    The challenge is the background. Traditional LCDs are black. E-ink are beige.

    The PixelQI display is the one that comes to mind. Granted, it's not exactly like this patent. The point is that the technology exists already, so This patent applications shouldn't hinder development at all.



    The new "Pearl" eInk technology found in the Kindle 3 and Kindle DX is VERY easy to read. Traditional books arn't white pages with deep black text. The contrast is softer than that. The New kindle screens are insanely easy to read, easier than a "real" book even, and a hell of a lot easier than any form of LCD.





    Reading on the iphone isn't bad because of pixel density, but it's still prone to strain if you read it for long periods of time. For myself, I like reading in the early morning or at late night. I don't want my pages lighting up the room around me.



    At this point i am as an Android user and Notion Ink Adam owner very interested in the fact that Apple tries to get a patent on something what already exists. Notion ink Adam features

    normaly i would say Apple wil copy something again and call out that they got something that will change the world.... again and again and again.



    What is there different in this patent than the patents from PixelQi exept from the country where it is dropped?

    Sorry, I was a but unclear.

    I mean most colour LCDs appear pitch black when you switch off the power. In order to make an e-ink layer visible on top of an LCD that's shut off, there needs to be a solution to temporarily make the background of the e-ink panel bright, without affecting the quality of the LCD. This is probably possible with some technical wizardry, but I don't think it's widespread.
