Low-voltage and high-speed ferroelectric liquid crystal devices for high-resolution driving in electronic holographic displays

Abstract We present a method to enhance the layered structure of surface-stabilized ferroelectric liquid crystals (SSFLCs) for low-voltage, high-speed operation in electronic holographic displays. By applying a combination of heating, slow cooling, and square-wave low-voltage (<1 V), we reduced the switching voltage and achieved sub-1 ms switching times, fulfilling the 360–720 Hz requirements for spatial light modulators (SLMs) in electronic holographic displays. The proposed method also suppressed zigzag defects, improving uniformity and light efficiency. This work advances high-resolution SSFLC-based SLMs for next-generation 3D holographic displays.
