Abstract

Analog display utilizing liquid crystal material and for being multiplexed wherein the segments (one group of electrodes) are arranged in groups opposite sectors (the counter electrodes) and wherein the segments in each group are disposed in a sequence opposite to the sequence in which the segments of the next adjacent group are disposed and, further, wherein a segment in each group corresponds to a segment in each other group and wherein all corresponding segments are electrically interconnected in a series connection. In timed sequence with the input signals applied to the sectors, input signals are applied to the segments in a first predetermined sequence with regard to a direction of display movement to be provided by the display, and alternately, the input signals are applied to the segments in an opposite sequence with regard to the direction of display movement whereby the display movement is in one continuous direction. The disposition of the segments in groups wherein the segments in adjacent groups are disposed oppositely, and the series connection of corresponding segments, permits the leads to the segments to be made by such techniques as evaporation, sputtering, photo-…
