Photonic crystal display materials

Opalux Incorporated has developed a technology called Photonic Ink (P-Ink). P-Ink comprises an electroactive photonic crystal which reflects a band of color that can be tuned throughout the whole visible spectrum by controlling the applied current or voltage. An overview of the P-Ink system and the latest results on this nanocomposite material will be given. In addition, results on Opalux´s 2^nd generation P-Ink materials will be presented, with these offering significant increases in brightness, contrast, and switching speed.
