Abstract:
Apparatus, methods and systems for a transmissive liquid crystal display including a plurality of pixel circuits, each pixel circuit including a reflective region and a transmissive region. The reflective region includes a polarization dependent reflector for reflecting ambient light. The reflective and transmissive regions include an initially homogeneously aligned liquid crystal layer sandwiched between a first and a second substrate. Each pixel further includes at least one first transparent electrode as the common electrode and at least one second transparent electrode as the pixel electrode both formed on one of the same first and second substrates, wherein substantial fringe fields with rich horizontal electric fields are generated in the liquid crystal layer when voltage is applied to the pixel electrode, making the liquid crystal molecules rotate mainly in the horizontal direction to achieve wide viewing angle.
