Elliptical LCD bar graph with path outline-defining segments
First Claim
1. A liquid crystal analog display device that displays along a predetermined path defined by a path outline, comprising:
- 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 segments and the path outline backplane sufficient to maintain the path outline image; and
means for selectively applying an electric field across said display segments and said display segment backplane for establishing an analog image display.

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.

8. A liquid crystal analog display device that displays an analog image display along a predetermined path that includes a number of major pickets representing a delineation of a higher order scale value, comprising:
-
a backplane defining the picket outlines; a plurality of display segments disposed along the path; a display segment backplane; means for applying an electric potential to said display segments; means for applying an electric potential to said backplane defining the picket outlines so that there is an a.c. field across the picket outline backplane and an associated display segment sufficient to maintain the picket outline image; and means for selectively applying an electric field across said display segments and said display segment backplane for establishing the analog image display. - View Dependent Claims (9, 10, 11, 12)
