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： 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： A display device includes a display module, a light source module and a guiding optical film. The display module includes a first substrate, a second substrate and a display medium. The light source module generates directional light. The display module has a vertical electric field. The display medium is optically isotropic, and the display medium is optically anisotropic when driven by the vertical electric field. The directional light is not perpendicular to the first substrate when the directional light enters the display nodule. The directional light is not perpendicular to the second substrate when the directional light exits the display module. The guiding optical film is disposed on the second substrate and has a light incident surface and a light emitting surface. After the directional light exits the guiding optical film, emitting light is formed, and the emitting light and the light emitting surface has an included angle there between.
