P‐251: Late‐News Poster: Application and Research of Optically Cholesteric Liquid Crystals in Reflective Displays

We have developed a single‐layer color reflective display using cholesteric liquid crystal, which changes the pitch of the liquid crystal through exposure, thereby altering the reflection wavelength and forming different colors. Single layer color cholesteric liquid crystal displays are not only lightweight and low‐cost, but can also be applied in harsh outdoor environments, signficantly enhancing competitiveness.
