We've seen an A4-sized sheet
of e-paper or two
in our day, but Epson's new prototype display features an absurdly high resolution for its size: 3104 x 4128, clocking it in at something like 385ppi. According to Fareastgizmos, E Ink's supplying the, um, electronic ink, while Seiko Epson built out the low-temperature polycrystal Si-TFT glass substrate medium. Yeah, we've got a long ways to go before we'll all be reading the e-paper morning news on the way to work, but it can't be that long, can it?
