P‐90: Tailoring Morphology in Holographic‐Polymer Dispersed Liquid Crystals for Reflective Display Applications

It is well known that the electro‐optics of holographic‐polymer dispersed liquid crystal (H‐PDLC) materials are critically dependent on the phase separation dynamics and the final polymer morphology. We therefore demonstrate and explore how multiple‐beam holography can be used to produce three‐dimensional arrays of LC droplets and characterize their effect on the electro‐optical properties of the reflection from these switchable films. We have exhausted many avenues to improve these materials in the context of reflective display applications and have found that this approach represents a novel way to beneficially modify the formation process.
