ABSTRACT:
A liquid crystal analog display device that displays along a predetermined path defined by a path outline. It includes a backplane defining the path outline; a plurality of display segments disposed along the path; a display segment backplane; a plurality of outline segments associated with the display segments for further defining the path outline; means for applying an electric potential to the display and outline segments; means for applying an electric potential to the path outline backplane so that there is an a.c. field across the path outline segment and the path outline backplane sufficient to maintain the path outline image; and means for selectively applying an electric field across the display segments and the display segment backplane for establishing an analog image display. There is also disclosed means for applying an electric potential to the backplane defining picket outlines so that there is an a.c. field across the picket outline backplane and the associated display segment sufficient to maintain the picket outline image.
