I don't follow. If you developed a special screen can't you profit just fine off selling the screen? Why would locked drivers be needed?

Well I don't understand the paragraph you wrote starting with "The problem, as Chitu figured out". Did they figure out an actual problem or did they hallucinate a problem?
Does their proprietary software affect their profit at all?

I did not write that paragraph, my friend.
I don't know why ChiTu does whatever they do. All I know is that demonstrate a trend of keeping their source buttoned up instead of open.

My bad.
But that paragraph is what my original question is about.

Chitu, IIRC, originally were open when they were using the initial color LCDs (off the shelf) and then the first iteration of monochrome ones (required NRE as nobody made 1920x1080 monochrom LCDs by then). And then everybody in the universe cloned them and Chitu got mad and Chitu made sure that the next iterations of monochrome LCDs had encrypted driver chips.
This isn't an unsolvable problem. It takes probably less than $100K (and probably less than $50K) in NRE to make a truly open-source monochrome LCD and driver chip. This is on the order of a plastic injection mold.
But everybody simply whines rather than banding together, coughing up the CASH, and actually FIXING the problem once and for all.
Sadly, this seems to be standard operating procedure in the world of open source.

How did everyone clone the first generation with monochrome LCDs though, if they weren't off the shelf?
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.)
