Bacteria make more stable flexible display material

摘要

There's a new flexible display material that avoids some common problems with other transparent organics by closely matching glass. Also unlike other organic substrates, this one is extruded by bacteria. Researchers from Kyoto U., Mitsubishi Chemical, and Pioneer have made a prototype electroluminescent dispky from the flexible transparent material, which contains fibers of bacterial cellulose (see figure). The fibers have about the same low coefficient of heat expansion as quartz glass, around 10 x 10~(-6)/K, or about 1/10 that of other flexible transparent organic materials. This low coefficient eliminates the usual problems with high-temperature processing, thin-film delamination, and electrode positioning.
