Flexible, Full-Color Electronic Paper Display Developed

For those of us inclined to read a great deal, devices with e-ink displays have been a wonderful medium for enjoying our favorite tomes. These displays, though, are monochromatic and rigid, so while they consume less powerful and can be read in direct sunlight, there are still uses they are not fit for. Researchers at Chalmers University of Technology, however, have discovered a means to create a full-color electronic display that is also flexible.

The researchers were actually working on placing conductive polymers onto nanostructures when they realized this technology would lend itself well to making electronic displays. The researchers built a prototype then that comes is less than a micrometer thick and can reproduce all of the colors of an LED display, while also using a tenth the energy e-ink displays in a Kindle require. This work however is only on a fundamental level, and that prototype only had a few RGB pixels in it, so there is still quite a lot of work to do before it can be deployed in a product.

Among the issues to address is the use of gold and silver in the display. While very little gold is actually used in the display, a lot of the precious metal is wasted in the current manufacturing process. A means to reduce the waste or decrease the cost will need to be discovered before commercial manufacturing is possible.
