There is currently no open source version of the high resolution monochrome LCDs. The LCDs and their drivers lock you into the Chitu ecosystem.
The problem, as Chitu figured out, is that as soon as you cough up the NRE to make the LCDs and make it publicly available, EVERYBODY will copy you and then there will be no profit left to sink the NRE that you just spent.
And that matters because statements like "just buy an open Chinese printer" are non-starters. The machines themselves have the soul of ChiTu inside of them and openness isn't really their jam.
So while the PC software that produces the layer images can be replaced, the printer's brains stays the same.
(This is very different compared to the world of conventional world of FDM printers, wherein: It's just some sensors, motors, heaters, and sensors; a screen, if present, is optional. A person can replace the brainbox of a traditional FDM Cartesian rig with open, off-the-shelf parts and be printing something in an afternoon, and there's a whole industry providing parts to support this kind of thing.
ChiTu isn't that way.)
