Kindle's answer to the ghost effect

Just thought I would point this out to the subscribers of this thread... I don't intend to be patronising in any way at all... I just think that what I am about to point out is pretty ingenius....


Have you ever wondered why the screen flashes to black when a new page is loaded?

Think of it this way.... A ghost image of the previous page is unavoidable... it's just the way the technology is (given that we have electronic ink that we can view in full sunlight, I think its a good compromise... anyway, back on-track)...

What the Kindle does is this... (when I realised this, it nearly blew my mind at how ingenious it is...)

... the Kindle loads the next page (the one it is changing to) as a negative of itself... in other words... the background of the new page is active ink (black) while the text is inactive ink (nothing)... then it reverses the page so that the text is the active ink.

The reason for this is an absolutely awesome workaround for the ghost problem...

THE GHOST FOR THE PAGE YOU ARE LOOKING AT IS THE BACKGROUND OF THAT CURRENT PAGE !!!

(due to the loading of the negative version of that page beforehand... if the kindle went straight from one page to the next it would obviously be illegible)

Obviously is doesn't work that well with some of the Kindles and I'm guessing that it is something that has happened to your particular Kindle during production because the only time I have ever seen a ghost is on the screensavers images (because it doesn't load a negative version first)... which is why it clicked why the screen flashes to black when changes pages.

I give Amazon a standing ovation for having designed the Kindle in this way (even if by chance it wasn't their own work that designed the epaper and eink display and the ghost workaround)... to this day my Kindle just blows my mind away!

*** I'm in Australia by the way, and I got my Kindle 2i from ebay Xmas 09... Kobo has just hit Borders and Angus&Robertson and our other major book retailer Dymocks has the bebook, while our HiFi and Office suppliers are starting to catch on as well... Officeworks here has 4 ereaders now including a blue-backlight LCD non-eink reader.... the stores are selling out as people catch on!!! GO EREADERS!!! ***
