摘要： Apparatus, devices, systems, and methods for wide viewing angle circular polarizers in transmissive and transflective displays. A liquid crystal display configuration can include two stacked circular polarizers, a liquid crystal layer, and a compensator between one of the circular polarizer and the liquid crystal layer to partially or fully compensate the liquid crystal layer. One of the circular polarizer is formed of a linear polarizer and a uniaxial quarter-wave plate, and the other circular polarizer is formed of a linear polarizer, a uniaxial quarter-wave plate, and a biaxial film interposed therebetween.

摘要： 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.
