    Abstract

    We have developed a new guest-host reflective display using a dye-doped dual-frequency liquid crystal (DFLC) gel. By combining dye absorption and maximal light scattering, the display is polarization independent and exhibits a high contrast (similar to 230:1). The high reflectivity (R similar to 50%) is because of the vertical aligned structure at 0 V-rms . The fast response time (similar to 5 ms) is also fast due to the frequency modulation. A black and white segmented-alphabet reflective display prototype is also demonstrated.
