A few days ago I got some feedback from someone who wanted to see what a PDF document looks like on the E Ink display. E Ink is renowned for its readability and high contrast without the use for a backlit like traditional LCD or LED based displays which can cause eye discomfort after prolonged usage. However, only the latest E Ink Triton displays are capable of colour reproduction (up to 4096 colours) whilst the original E Ink and E Ink Peral displays are limited to greyscale reproduction.
Anyway, I have taken some photos of the E Ink Pearl display on the Kindle DX, Please note that blurring is as a result of using a digital SLR so the centre of the photo will be most in focus.
Granted, I’m not the best photographer in the world but hopefully you can see how similar the display is to traditional paper. What I would recommend you do though is get out to a store such as Borders (as long as they don’t completely go under) and have a look at the eBook readers there. Of course, you won’t find a Kindle in there (unless they are desperate) but you’ll get an idea of what one looks like hands on.
