Fountain Field Technology for Wide Viewing Angle LCD

Due to anisotropic character of the liquid crystal optical properties, the electro-optical response of the majority of LCDs modes possess an angular viewing angle dependence. Combinations of different complementing optical elements are included in the LCD architecture for reducing such a dependence. We suggested and realised a novel electrode structure for LCDs, Perforated Electrode (PE), for generating a Fringe Field Switching (FFS), which is enabling to generate images with 360º viewing angle constant contrast. This electrode structure provides generation of local electric fields, distributed over the whole work area of the LCD, possessing azimuthally degenerate directions around the holes, which in turn induces realigning of the liquid crystal molecules according the directions of the local electric field, i.e. the field-on liquid crystal alignment will become with locally azimuthal degenerate directions. Hence, the generated images will possess azimuthally viewing angle independent contrast.
