e-paper displays, one in black-and-white and one in color. The approximately 24-inch readers were created by Delta Electronics (no relation to the airliner) and are being used by a local newspaper publisher to survey attendees and gauge interest in their future use. Our friends at Engadget Chinese tell us the color one is less contrasty than its monochrome partner, but beyond that, details are scarce and no one at the booth could provide any specs. One thing's for certain: they're a helluva lot crisper than those 28-inch e-paper billboards popping up around Tokyo. Hit up the read link for more pics.
