Abstract

We investigate the electrooptical properties of polymer-stabilized vertically aligned (PSVA) pi cells. Curing a cell with a curing voltage causes the polymerized cell to have a low threshold voltage and a fast field-on response time, because the curing voltage gives the polymerized cell in-cell polymer structures, inhibiting the flow of the liquid crystal (LC) domains and also providing the LCs a sustained pretilt angle. Additionally, under high-voltage operation, the field-on and field-off response times of the PSVA pi cell operated under the step voltage driving scheme are found to be less than those of the cell operated under the conventional bias voltage driving scheme, because the electric torques exerted on the LCs in the step voltage driving scheme are higher than those exerted on the LCs in the bias voltage driving scheme,
