Ask HN: Are larger one-bit display panels available?

The Playdate display panel intrigues me and I want to experiment with a much larger version of it. Do those panels come in sizes greater than 4-6 inches? Ideally what I’m looking for is 14” to 15”. I’ve searched around and can’t find anything larger than approximately the size of a Kindle screen.

Can they be custom ordered? Anyone know what costs look like if you go that route?
