While this display is really slick, it seems like it is still not available under multiple suppliers? If thats the case. that means its going to be more pricey than other options. I cant seem to find many cheap options on alibaba/aliexpress.

Apparently Sharp introduced the technology in 2009, so perhaps there's a patent expiring soon?

How do those compare on price though?

Well that one's from Adafruit, so probably 10x the price of what's commonly sold.
