Development of Paper Base Display Device
Ricoh Japan along with Agri Bio Industry of Japan and School of Graduate study at Hokkaido University made a joint announcement on development of new display device made of paper. The newly developed paper is made of bacteria cellulose. The prototype is comprised of sheet of bacteria cellulose paper with electrode directly attached to it. They have successfully tested the display ability of the new paper by exciting the contained pigment in the paper. The current displays are fabricated on glass or plastic substrate but the newly developed paper will eliminates any needs for such materials resulting in a simpler fabrication process for display. Bacterial cellulose has a network structure of thin fibers with thickness of 1/1000 of plant fiber with a high water retention ability and durability plus biodegradability characteristics. Based on the three studies, through use of non-edible materials they have succeeded in synthesizing bacterial cellulose at a low cost. The new material features porosity with a uniform thickness suitable for a display device, while maintaining its micro-structure. The study is still at the early stages with practical application still distance away.
