Reduction of the switching time of polymer-dispersed liquid crystal using field oriented addressing

Polymer dispersed liquid crystal (PDLC) is a promising liquid crystal for reflective displays in low power mobile applications. However, it is difficult to obtain full color PDLC displays. Color sequential PDLC is one solution but this requires short PDLC switching times. It is demonstrated that the PDLC switching times can be reduced to color sequential levels by changing the orientation of the electric field (field-oriented addressing). By choosing the right pixel geometry, this can be done at relatively low switching voltages compared to the classic addressing method which is based on changing the magnitude of the electric field.
