Tunable photonic crystal color filter and color image display apparatus including the same

摘要

A tunable photonic crystal color filter and a color image display apparatus including the same. A tunable photonic crystal color filter includes a first electrode, a second electrode on the first electrode, and a medium disposed between the first electrode and the second electrode. The medium includes charged nanoparticles having a lattice structure in the medium. The first electrode and the second electrode are formed of a material having a difference between an oxidative over-potential and a reductive over-potential.

1. A tunable photonic crystal color filter, comprising:
a first electrode; a second electrode on the first electrode; and a medium disposed between the first electrode and the second electrode, the medium including charged nanoparticles having a lattice structure in the medium, wherein the first electrode and the second electrode are formed of a material having a difference between an oxidative over-potential and a reductive over-potential, the difference between the reductive over-potential of the first electrode and the oxidative over-potential of the second electrode is within a range of about 0.1 V to about 10 V such that occurrence of electrolysis in the medium is suppressed, and the first electrode is formed of diamond doped with boron.
