• Subjects: DEVICES OR ARRANGEMENTS, THE OPTICAL OPERATION OF WHICH ISMODIFIED BY CHANGING THE OPTICAL PROPERTIES OF THE MEDIUM OF THEDEVICES OR ARRANGEMENTS FOR THE CONTROL OF THE INTENSITY,COLOUR, PHASE, POLARISATION OR DIRECTION OF LIGHT, e.g.SWITCHING, GATING, MODULATING OR DEMODULATING; FREQUENCY-CHANGING; NON-LINEAR OPTICS; OPTICAL ANALOGUE/DIGITAL CONVERTERS; OPTICAL LOGIC ELEMENTS; OPTICS; PHYSICS; TECHNIQUES OR PROCEDURES FOR THE OPERATION THEREOF

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.
