摘要： 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.

摘要： A novel nematic liquid crystal (LC) mode is based on the Fringing-Field-Switching of Vertically-Aligned liquid crystals. The VA-FFS mode is capable of generating very fast optical modulation without the use of very thin cell gap. IA major feature of this LC mode is that it has unusual fast relaxation time compared with the conventional nematic LC modes that require a thin cell gap. This fast relaxation occurs even at very low applied voltages and the operation is very stable. The fast-response mechanism of this LC mode involves the confinement of liquid crystal molecular switching within self-imposed thin LC layers. The present invention provides a novel approach to overcome the fundamental problem of the long relaxation time of the conventional nematic liquid crystal modes.

摘要： A wide viewing angle transflective liquid crystal display includes a retardation film and pixels positioned between first and second substrates, each pixel including a transmissive region and a reflective region. The retardation film has a phase retardation that compensates the phase retardation of a liquid crystal layer in the transmissive region for normal incident light to achieve a dark state when no data voltage is applied to the pixel. The retardation film and a liquid crystal layer in the reflective region has a phase retardation in a range between 0.22λ and 0.28λ with respect to normal incident light to achieve a dark state when no data voltage is applied to the pixel, λ being the wavelength of the incident light.
