Taiwan’s Industrial Technology Research Institute has developed e-paper technology which it expects to be used for digital signage. ITRI demonstrated prototypes of the e-paper (not pictured) that it hopes will be commercialized within the next two years.
The e-paper can print red, green, and blue in different parts of the paper and utilizes a roll-to-roll printing process that is currently used in newspaper presses. One example the ITRI demonstrated was an e-paper clock that refreshes electronically with each second. The research institute also noted other uses, such as e-wallpaper and e-tickets, which could be recycled and reprinted for hundred of events.
