  • Publication number: 20130201433
    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 to 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.

  • Publication number: 20130201181
    Abstract: A stereoscopic image display system includes a three-dimensional (3D) image signal generator, a display panel, a timing controller, a data driver, and a gate driver. The 3D image signal generator generates left-eye data and right-eye data on the basis of an image signal outputs the left-eye data and the right-eye data to the timing controller. The timing controller outputs the left-eye data and the right-eye data having a first frequency to the data driver in a first mode and outputs left-eye frame data and right-eye frame data having a second frequency to the data driver in a second mode. Two pixels, which are respectively connected to an i-th gate line and an (i+1)th gate line among the gate lines and to a same data line among the data lines, are operated with the same driving time in the first and second modes.
