Step-shaped electrode for low-voltage and high-optical-efficiency blue-phase transflective liquid crystal displays

摘要

A step-shaped electrode design is proposed for Polymer Stabilised Blue Phase (PSBP) Transflective LCD (TR-LCD). This new electrode design is capable of delivering very high optical efficiency (both T and R) of >95% with operation voltage of ~13V (or >~90% with ~9V). The step-shaped electrode helps generate strong horizontal electric fields across the whole cell and suppress the formation of dead zone.
