  • Patent number: 9568797
    Abstract: A flat panel display having an improved picture quality is disclosed. In one embodiment, a first pixel electrode and a second pixel electrode are formed in each subpixel area. The electrodes enclose an open space (gap) such that their outer boundary has a substantially rectangular shape. The flat panel display may also include a capacitance electrode coupled to the second pixel electrode to form a coupling capacitor. In use, the coupling capacitor operates such that a magnitude of a voltage applied to the first pixel electrode is lower than an applied data voltage, and a magnitude of a voltage applied to the second pixel electrode is higher than an applied voltage. The different voltages operate such that a tilt direction of LC molecules disposed above the first pixel electrode differs from a tilt direction of LC molecules disposed above the second pixel electrode.

  • Publication number: 20160223871
    Abstract: A tetragonal ring shape aperture is formed in the common electrode on one substrate and a cross shape aperture is formed at the position corresponding to the center of the tetragonal ring shape aperture in the pixel electrode on the other substrate. A liquid crystal layer between two electrodes are divided to four domains where the directors of the liquid crystal layer have different angles when a voltage is applied to the electrodes. The directors in adjacent domains make a right angle. The tetragonal ring shape aperture is broken at midpoint of each side of the tetragon, and the width of the aperture decreases as goes from the bent point to the edge. Wide viewing angle is obtained by four domains where the directors of the liquid crystal layer indicate different directions, disclination is removed and luminance increases.
