Reverse-voltage-driven sub-millisecond response LCDs for AR/VR displays

We demonstrate a patterned vertically aligned (PVA) liquid crystal display (LCD) driven by a reverse-voltage scheme that achieves submillisecond response times (0.52 ms). Both simulations and experiments confirm that the device consistently operates within the submillisecond regime, thereby validating the feasibility of the proposed approach. This method optimizes the LC molecular deformation dynamics and reverse-bias driving strategy, effectively overcoming the intrinsic response-time limitations of conventional in-plane switching (IPS) and fringe-field switching (FFS) LCDs, consequently meeting the core requirements of next-generation augmented reality (AR) and virtual reality (VR) display technologies for improved dynamic display performance.
