It's not patents, it's literally artisanal handcrafting prices - they produce these giant e-ink screens by fusing together 4 smaller screens, and they do so by hand because there's almost no demand for $1000 1Hz screens, so they haven't automated the process. >just about every other display tech came down in price by a factor of 10 a few years after it was invented. No, the successful display techs came down in price. The commercial flops that nobody hears about are the same price as always (i.e. astronomical), because they have no economy of scale.
