After announcing the Galaxy Z TriFold's price and release date for the U.S. market on Tuesday, Samsung on Wednesday unveiled a different gadget with a unique display. The 13-inch Samsung Color E-Paper features the world's first display housing made in part with a bio-resin crafted from phytoplankton. Phytoplankton refers to microalgae that live in water, but Samsung's announcement doesn't explain how the phytoplankton is turned into a bio-resin material, or how it's mixed with plastic. The Color E-Paper's display housing isn't made entirely of bio-resin. Only 10% of the material used for the housing comes from phytoplankton, with about 45% made from recycled plastic.
