I'm guessing these are all "left over" or superseded feature phone components. I've got a few from a couple of years back that are explicitly sold as "Nokia screens" and all the library code makes it pretty clear they're Nokia 3xxx series phone parts.

The "hobbyist LCD" market doesn't get purpose designed components - not at the volumes and prices hobbyists are prepared/capable of buying. We get to re-use end-of-life components or buy the end-of-reel scraps from current product manufacture. (which is fine by me. I love being able to buy accurate 9DOF IMUs, but I sure as hell don't want to order them in reels of 10,000 un-hand-solderable SMD parts)
