While E Ink is certainly the clear leader in the e-paper market, some companies are developing what they hope will become next-gen e-paper displays. Bodle, based in Oxford, UK, is developing a technology it calls SRD, based on research that started in Oxford University a few years ago.
SRD, or Solid-State Reflective Displays, creates color using light interference inside an ultra-thin film. The film contains a phase-change material, the same one used in writable CD-R discs. When this material is switched between its amorphous and crystalline phases, the color is changed.
