Abstract

A display includes pixel circuits, each pixel circuit including a first electrode, a second electrode, a third electrode, and a liquid crystal layer doped with a chiral material. The first electric is electrically coupled to a first reference voltage. The second electrode receives a pixel voltage corresponding to a gray scale level, the second electrode including a conducting layer having openings. The third electrode is electrically coupled to a second reference voltage. The second electrode is between the first and third electrodes, and the liquid crystal layer is between the first and second electrodes.
