illustrates the structure and principle of the proposed 1DII display. It consists of a display panel, a parallax barrier, and a barrierarray. The barrier array is perpendicular to the display panel and the parallax barrier. Each barrier is located at the junction of adjacent elemental images. Thus, lights emitted from the assigned element alimage are modulated by the assigned slit, while lights emitted fromo ther elemental images are blocked by the barrier array.
