Hello Rapefruit,
you're lucky. Not because you get the replacement display from PVI, but because to replace an e-ink display involve also to reload the correct waveform associated to that display.
Probably, the waveform of the replacement display was similar to the WF loaded in your reader. Maybe you have noticed an increment of the "ghost effect" in your reader. This is because the WF is not correct for your display.
The WF is a small file with the description of the characteristics of the display, and depends by the production lot of e-ink active particles.
Every lot of displays has a different file. To reload it into the reader, you need an hardware and/or software tool.
Moreover, there is also a cailbration to do, related to that small value written on the flexible part of the display (the -1,36 visible on your broken display, different from display to display.
I suggest to avoid to do the replacement DIY, because you can get a unusuable reader, because the ghost effect.
