A high‐efficiency (97%) fast polarization converter (100 kHz) is achieved using Ferroelectric Liquid Crystal (FLC). Innovatively, by cascading FLC cells, no diffraction and residual light loss are achieved. The flickering is less than 5%.. The contrast ratio is 1000:1. Bi‐stable focus modulation is acheived. It is a promising candidate not just for display technologies, but also for high‐ efficiency beam‐steering applications, such as Virtual Reality (VR)/Augmented Reality (AR), Light Ranging and Detection (LiDAR).
