Latest Patents

One of his latest patents involves a novel liquid crystal display design. This LCD features liquid crystal molecules that are oriented in a specific direction around a valley formed in the upper substrate. This design aims to prevent the formation of an unadjustable disclination line. The LCD consists of an upper substrate, a lower substrate, and multiple slits in the pixel region of the lower substrate, with each slit positioned at a minimal distance from its neighbor. A valley is created in the color filter of the upper substrate, which is covered with a transparent electrode and is aligned at a predetermined angle with respect to the slits. Vertical alignment material is applied to the opposite faces of the upper and lower substrates, with a liquid crystal layer injected in between. Additionally, polarizers are placed on the outer faces of both substrates, oriented perpendicularly to each other.

Another significant patent by Seong Wook Shin is for a VVA mode LCD. This display features a liquid crystal layer with negative dielectric anisotropy situated between the upper and lower substrates. A pixel electrode is located on the lower substrate, while a color resin layer on the upper substrate includes a V-shaped valley and shallower jagged valleys that are perpendicular to the V-shaped valley. A counter electrode is formed on the color resin layer, mirroring the valley structure. The design incorporates first and second vertical orientation layers between the pixel electrode and the liquid crystal layer, as well as between the counter electrode and the liquid crystal layer. First and second polarizers are attached to the outer and inner faces of the upper and lower substrates, respectively, with their polarization axes intersecting.
