Abstract

This work demonstrates a dual-frequency polymer-stabilized liquid crystal pi cell with zero bias and a short response time. The high curing voltage and low curing intensity give the cell a low dark state and a high bright state, such that the transmittance against the applied voltage curve is steep. The response time is under 1 ms and is independent of monomer concentration because a strong electric torque is exerted on the liquid crystals. The cell is useful in field-sequential color systems, and the low operating voltage of ∼5 V makes the cell compatible with conventional thin film transistor driving voltages.
