Here is a teardown of a 13.3 high perf E-ink monitor I did a few months ago: https://kevzettler.com/2018/02/11/dasung-paperlike-pro-teard...

The post identifies some on market E-ink display components and discusses the design of a proprietary display driver.

"On closer inspection all the chip components have had their labels chemically peeled off to prevernt reverse engineering."

Wow, I've never seen that. Is it a common thing? It also puts me off buying one of these (assuming the $900 price tag hadn't put me off already).

I've seen it a lot in Chinese electronics, and it only deters the least effort of reverse-engineers.

Erased markings are usually a sign of off-the-shelf parts; they didn't go to the effort of printing their own branding on them.

Did you eventually switch the panel to ES133UT2? Dasung released a new version called paperlike HD (also called paperlike 3). In that version, it does not look like having a glass panel.

I have acquired an ES133UT2 (and data-sheet with what appears to be waveforms) but have not replaced it because I damaged the cover of the Dasung during disassembly which means the display module would not be held securely to the screen.
