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.
A color image display apparatus, comprising:
- a first electrode;
- a second electrode on the first electrode;
- a medium disposed between the first electrode and the second electrode, the medium including charged nanoparticles having a lattice structure in the medium, wherein a lattice interval between the nanoparticles varies according to a magnitude of a voltage applied between the first electrode and the second electrode;
- a circuit layer including a switching device configured to apply the voltage to the first electrode and the second electrode;
- and
