摘要： A liquid crystal display includes a first alignment film having a first alignment direction, a second alignment film having a second alignment direction, and a liquid crystal layer having liquid crystal molecules between the first and second alignment films. The liquid crystal layer is doped with a chiral material that tends to induce a first twist in directors of the liquid crystal molecules when an electric field is applied to the liquid crystal layer. The first and second alignment films have orientations that tends to induce a second twist in the directors when an electric field is applied to the liquid crystal layer, in which the direction of the first twist is different from the direction of the second twist.

摘要： A liquid crystal display includes a first substrate having a first electrode and a first alignment film, a second substrate having a second electrode and a second alignment film, and a liquid crystal layer having liquid crystal molecules between the first and second substrates. The liquid crystal layer is doped with a chiral material that tends to induce a twist in directors of the liquid crystal molecules when an electric field is applied to the liquid crystal layer using the first and second electrodes. The first alignment film has a first alignment direction, the second alignment film has a second alignment direction, and the first and second alignment films have orientations that tend to induce a twist in the directors when an electric field is applied to the liquid crystal layer, in which the direction of twist induced by the first and second alignment films is different from the direction of twist induced by the chiral material. The display includes a reflective layer to reflect external light that passes a first portion of the liquid crystal layer. The external light is modulated by the first portion of the liquid crystal layer.

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.
