A wide-view transflective display using a polymer-stabilized blue-phase liquid crystal

A low-power, wide-view, and single-cell-gap transflective display using a polymer stabilized blue-phase liquid crystal (BPLC) is proposed. To reduce operating voltage, we use protrusion electrodes to generate strong fringing fields to penetrate deep into the bulk liquid crystal layer. To balance the optical phase retardation between transmissive (T) and reflective (R) regions, we design the R region with a wider electrode gap so that its smaller induced birefringence compensates the double pass of the ambient light. To reduce power consumption, we utilize the fast-response feature of BPLC for field sequential display which triples the optical efficiency and resolution density.
