Abstract :
A transflective polymer-stabilized blue-phase liquid crystal display (BP-LCD) using an etched in-plane switching (IPS) structure is proposed. To balance the optical phase retardation between the transmissive (T) - and reflective (R) -regions, IPS electrodes are formed with the same dimensions in both T- and R-regions, and the substrate between the electrodes is etched for generating double-penetrating fringe fields only in the T -region . This display exhibits a reasonably wide viewing angle and well-matched voltage dependent transmittance and reflectance curves.
