Description
Summary:In this paper, we propose a novel patterned vertical alignment (PVA) architecture with a single cell gap for transflective operation of an LC cell. The proposed architecture has a feature wherein a chevron-shaped electrode is rotated by 90 degree in the counterclockwise manner in an effort to significantly improve the aperture ratio. Since the data line is located under the pixel electrode, we can efficiently eliminate the space between the data line and the pixel electrode. Our numerical simulation revealed that the aperture ratio of the proposed transflective PVA cell improves approximately by 4.8% over the conventional transmissive PVA cell.
