P‐128: Viewing Angle Switching of Liquid Crystal Displays Driven by Fringe Field Switching

We propose a pixel structure of viewing angle switchable liquid crystal display associated with fringe-field switching (FFS) mode using one panel. In the device, one pixel is composed of main- and sub-pixel, in which both pixels are formed to generate fringe electric field. However, the fringe field direction is different each other such that in the main pixel, fringe field rotates liquid crystal (LC) making its optic axis deviating from polarizer axis but fringe field only tilts LC upward without rotating in the sub-pixel region. In this way, light leakage can be generated in the sub-pixel, which can block displayed images in an oblique viewing angle.
