Abstract:
Aspects of the present disclosure relate to single-domain electrode configurations that may be implemented in the unit pixels of a LCD device, such as a fringe field switching (FFS) LCD, to provide a “pseudo-multi-domain” effect, wherein the benefits of both conventional single-domain and multi-domain pixel configuration devices are retained. In accordance with aspects of the present technique, single-domain unit pixels are angled or tilted in differing directions with respect to a vertical axis of the LCD panel (e.g., y-axis) to provide an alternating and/or periodic arrangement of different-angled pixel electrodes along each scanning line, data line, or a combination of both scanning and data lines. In this manner, the transmittance rates of conventional single-domain LCD panels may be retained while providing for improved viewing angle and color shift properties typical of conventional multi-domain LCD panels.
