ABSTRACT:
A magneto-optical liquid crystal display responds to the direction of a provided magnetic field. Display alternatives include a compass-like dial indication of direction, numeric values, and complex pixilated images. By providing a variable magnetic field, the display may be used as a non-contact remote analog gauge or digital indicator.
