Techniques are provided for transflective LCDs using homogeneously aligned liquid crystal materials which optical birefringence is electrically controllable. An unpaired retarder may be configured to compensate, in transmissive parts, for the effect of reflection in reflective parts. A light recycling/redirecting film may be added between a BLU and a nearby polarization layer to recycle backlight from a reflective part of an LCD unit structure into a transmissive part of the same structure to increase the optical output efficiency of the BLU. Electrodes for the transmissive part and the reflective part may be separately driven in various operating modes. Benefits include high transmittance, high reflectance, wide view angles, improved optical recycling efficiency, and low manufacturing costs. |
