Abstract: Method, system and device for a transflective liquid crystal display with both transmissive and reflective functions is realized by using a transflective component into a transmissive LCD. The transflective component can be a transparent substrate with patterned reflectors on one surface and repetitive patterned lenses or prisms formed on the opposite surface facing the backlight unit. The transparent areas substantially allow the optical beams to pass through. The light from the backlight is refracted or focused by the optical structures onto the transparent areas or apertures of other surface, thus a substantial amount of backlight transmits to the LC for light modulation for different gray levels. For the incident ambient light incident on the transflective component, the majority is reflected back to the viewer by the reflectors on the transflective component, and the remainder transmits the transflective component to the backlight unit and be recycled to be used again.

Abstract: A transflective liquid crystal display with uniform cell gap configuration throughout the transmissive and the reflective display region is invented. Mutually complementary common electrode pattern and reflector pattern or mutually complementary ITO pixel electrode pattern and reflector pattern produce an electric field in the transmissive display region that has a uniform longitudinal field and an electric field in the reflective display region that is a fringing field. An initially vertically aligned negative dielectric anisotropic nematic liquid crystal material between the electrodes forms a smaller tilt angle with respect to the substrate normal in the reflective display region while a larger tilt angle with respect to the substrate normal in the transmissive display region. Consequently, the ambient incident light experiences smaller phase retardation in the reflective display region while the light from the backlight source experiences larger phase retardation.
