Abstract
A multi-character multi-segment electrically address
able display panel. Character segments (a to h) are defined
at each of a number of adjacent locations by the overlap of
two sets of electrodes (Fig. 6; Fig. 7). The electrodes of one
set (Fig. 7) are each associated with a location and a group
of one or more segments [(a, b, g); (c, e); (d, f); (h)]. The
electrodes of the other set (Fig. 6) extend across each
location and are associated with no more than one segment
in each segment group [(a); (b, e, f); (c, d, g)]. The panel is
addressed using isogonal signals - eg pseudo-random bi
nary sequence coded signals. The panel medium may be of
dyed or undyed cholesteric-to-nematic phase change effect
liquid crystal material, of low threshold or wide temperature
range liquid crystal material.
