Kyoto University, Pioneer Corporation, and Rohm Corporation announced that they have developed two new technologies for flexible displays: a “bio-luminescent transistor,” an organic transistor with EL(electro-luminescence) capabilities, and a “low heat expanding transparent substrate,” through reinforcement of the original bio nanofibers. Using these new technologies, it is now possible to create flexible displays that are light, resistant and displaying on curved surfaces. Possible applications include flexible displays, electronic paper/newspaper and electronic posters. Cool! I always wanted to get rid of paper! In addition to being low-tech, paper usage hurts the environment…Protect the trees! (Sometimes, just for drawing, paper makes it more enjoyable :)) Read the details about the technology in the full post. |
Bio-nanofibers ? This could be the next technology that powers the new flexible displays in the near future.The bio-luminescent transistor with its EL (electro-luminescent) capabilities combined with an active-matrix type display device allows for the composition of a device with a powered transistor and light element – which means a lot less parts than the current EL displays.
The low heat expanding transparent substrate is flexible, and it is based on transparent nanofibers, organic in origin, that can reinforce transparent polymer materials. The Alliance has dubbed this material “Bio-nano fiber composite.”
Currently, the conventional polymer materials were laid on top of a substrate, exposed to heat during the production process. The differences in thermal expansion coefficients of the substrate materials would lead to severed lines, making damage possible, and this remained as the main issue in the manufacturing of flexible displays.
The bio-nanofiber composite consists in transparent fibers with an under 100nm diameter, it retains flexibility and offers both a light transmission efficiency of over 85% in transparency and a low thermal expansion coefficient. The nano-size of the fiber induce that the transparency is not controlled by differences in bending coefficient and resin. The fibers’ filler shape allows reducing significantly the volumetric mean between the thermal expansion coefficient of the filler and matrix resin.
