摘要： A transflective display includes pixels each including a reflective (R) sub-pixel, a transmissive (T) sub-pixel, and electrodes having features to cause multiple domains to form in a liquid crystal layer of the R sub-pixel and the T sub-pixel. The electrodes in the R sub-pixels have features that are different from features of the electrodes in the T sub-pixel to cause the liquid crystal layer in the R sub-pixel to have an optical phase retardation that is between 20% to 80% of an optical phase retardation of the liquid crystal layer in the T sub-pixel. The R sub-pixel and the T sub-pixel have substantially the same cell gap and are driven by the same pixel voltage.

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.
