Ok, I understand, look at the image I inserted in my post

*
The things I circled are the "drivers" (or what they called "display chips")
The current eInk Vizplex screen is a little different (this photo seems to come from an early prototype, there is now only two drivers on the border (instead of three on this photo or it is bigger than 6 inch)
So this could be what they call "display chips" in your case. I doubt that an defective Apollo chip could led to the symptom you had.
The "drivers" can be damaged from a lot of reason, from a real defective screen, to bend, hits etc...
And this is not necessarily due to a broken glass.
