Abstract

A fast response time, wide viewing angle, and single-cell-gap transflective display using polymer-stabilized blue-phase liquid crystal is proposed. The transmissive region has an in-plane wall-shaped electrode while the reflective region has an in-plane trapezoid electrode. Both of the electrodes generate a strong horizontal field, resulting in a low operating voltage and high transmittance and reflectance. In every driving voltage, the effective cell retardation value in the transmissive region is larger than that in the reflective region, so that the transmissive and reflective regions have similar gamma curves.
