But liquid nitrogen is cold enough for the shift to be dramatically visible. We’d love to see the color shift associated with other cryogens, or see what happens with a blue LED. Want to try ...

The liquid crystal panel cycles between red, blue, and green tints in time with the CRT’s images behind it, creating a full-color picture. “But wait!” you cry. “Surely there were small ...

Instead, they placed tiny liquid crystal droplets into a polymer film. “That way we could encapsulate chiral liquid crystals and deform them in very specific, highly controlled ways,” de Pablo said.

Color liquid crystal grating based color holographic 3D display system with large viewing angle Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Journal ...

A research team in Korea has developed a material that may potentially replace color shifting ink in prevention of forgery of bank notes, ID cards, and so on. A team headed by Dr. Sang-seok Lee ...
