ABSTRACT:
An array of display elements are driven between ON and OFF positions where an element bright side is or is not displayed in the viewing direction by a magnetic field individual to each element. A Hall effect switch is located in each field and used to control a circuit in accord with the field polarity. The circuit may be used to provide lights which augment the appearance of an element in a viewing direction. A power control circuit using a phase control and a clipper is used to power the lights and the Hall element.
