PW5 Paperwhite 11th screen change.

eddie.t.h · 03-22-2024, 11:38 AM

Hi everyone!
I have replaced the screen on my Kindle Paperwhite 11th and I have a small problem. It looks like the new screen has a much lower VCOM voltage and the picture gets darker and darker every time I switch pages. Does anyone know a way to adjust this voltage? Is there a serial port on this model? Unfortunately the reader is on the latest sofet so jailbreak is out

On previous models you could set this in u-boot or they would pull themselves from the display memory.

This why various people has written that changing eink isn't like swapping an LCD. Swapping a battery is worthwhile. Very many eink models it's hit or miss what image quality you get and few models let you change the calibration.

You'd have to know the setting for your screen and you'd have to know how to apply it if it's possible. So really, you'll need a new PW5.
