Blue-Phase Liquid Crystal Displays With Vertical Field Switching

A low-voltage, high-transmittance, hysteresis-free, and submillisecond-response polymer-stabilized blue-phase liquid crystal (BPLC) display with vertical field switching (VFS) and oblique incident light is demonstrated. In the VFS mode, the electric field is in longitudinal direction and is uniform. By using a thin cell gap and a large oblique incident angle, the operation voltage is significantly reduced which plays a key role to eliminate hysteresis and residual birefringence. The VFS mode is a strong contender for the emerging BPLC display and photonic devices.
