Photonic Liquid Crystals

project report

Our goal is to combine two very interesting types of crystals - photonic crystals and liquid crystals. This combination would allow novel displays that could be easily used in direct sunlight as they would use reflected light rather than transmitted light. They would also allow a higher resolution as they would be able to display all colors using a single pixel without subpixels.

Initially, we studied the properties of photonic crystals and liquid crystals. We built a liquid crystal display and we fabricated and studied photonic crystals at school. Then we mixed liquid crystals with different additives aiming to structure them and to produce photonic crystals consisting of liquid crystals. It turned out that the combination of both crystals is significantly more challenging than we had expected.
