Figure 1. Diagram of the Bio-inspired colour-generation system.

Inspired by the colour-generating photonic structure of mammalian skins and avian skin/feathers and their communication methods, we propose a novel full-colour display device for information delivery. In our system, self-assembly of M13 phage leads to a photonic crystal structure that serves as an RGB colour filter layer of a common display device. By adopting the virus colour film as a colour-generating source, there is minimal energy loss, in contrast to common colour displays.
