How is it that unbearably low-res hobby/project LCDs are expensive but high-DPI "retina" iPhone screen replacements are $10 each? Anyone have adapters to drive the latter?

Nice. But it needs to be an integrated product, preferably in tiny form factor, before it's practical IMO.

If it were an ASIC you could make them for a few cents each at scale (would require large-scale products integrating cheap iPhone screens). Existing design could probably be minified putting more of it in the FPGA, reusing existing tiny FPGA board.

Rich, don't take me the wrong way, but you asked why iPhone replacements were only $10. That's because the screen is dirt cheap, all the circuitry to drive it though is what is expensive. Someone out there has to build the code to drive it, then spin an ASIC (at scale). $$$$$$$$$

No-one targeting the market that is looking for small screens is going to see a return on their investment anytime soon. The smaller screens generally come with a piggyback board already designed that was churned out in China years ago.

This is only partially true. These MIPI displays already contain quite a bit of complicated driver circuitry in them. It's true that no hobbyist can compete with the scale of Apple, but it's definitely possible to make a reasonably affordable adapter.

I don't know, and that's why I asked, but I find it difficult to believe the controller logic is the difference in cost. It seems more likely that one market just hasn't caught up to the economy of scale of the other.

The controller logic certainly isn't the difference in cost. It's entirely the massive scale of Apple vs the tiny scale of hobbyists.

I just wish the latter were building on what the former made cheap rather than selling backwards stuff for high prices...
