Transflective blue-phase liquid-crystal display with corrugated electrode structure

A transflective polymer-stabilized blue-phase liquid-crystal display (BP-LCD) with a corrugated electrode structure is proposed. To balance the optical phase retardation between the transmissive (T) and reflective (R) regions, two device structures are proposed. The first device structure has the same inclination angles but different cell gaps in the T and R regions. And the second device structure has the same cell gap but different inclination angles in the T and R regions. Both of the device structures can obtain well-matched VT and VR curves. This display exhibits low operating voltage, high optical efficiency, and a wide viewing angle.
