Amazon Kindle e-ink Screen Transplant from a Sony Reader

Step 6Success! (Sort Of...)

Success! (Sort Of...)
Boy, seeing that Amazon logo pop up was like Christmas. After eight months, my $400 device was Alive again!

...Kind of. There are a couple of problems. There's significant "ghosting" on the screen (faint imprints of previous text or images) when you turn pages, which wasn't as bad with the original screen. According to OrgangeTide in his comment below:

"The e-Ink controller has waveform data that is matched to the display material. Also there is a temperature compensation that is unique for every display. These two factors are going to result in significant ghosting."

Second, as I mentioned before, the Previous and Next Page buttons on the left don't work. I've thought about some sort of modification, but I don't want to undo everything I did and risk it breaking again. The Next Page on the right works- if I need to go back I suppose I can use the menu Go To Location feature.

Third, there's bulging around the LCD bar as some of the metal juts into it. As some of the metal actually rests on the bar, I'm very careful about applying any pressure around that area.

Besides those caveats, some of which would probably be solved with some better Dremel work, it seems to be fine. All the free samples I sent to my Kindle through amazon during the past eight months downloaded fine, and it remembered my place in all the books.

The scroll wheel works good, even though it's not completely set properly, and it's very easy to read, even with the ghosting.

All in all, I'm glad to have my little device back.

I'm sure the factors that OrangeTide mentioned don't help, but the PRS-500 has a very ghost-prone display anyway. I've got one in front of me right now and every time you change the page, a very visible ghost of the previous page stays on the screen forever, until you change the display again.

I'd be interested to see what it would look like if a less ghosty display (like the one from the PRS-505) was used. Nobody's going to be sacrificing one of those any time soon, though!
