Liquid crystal display device

Claim 1

A liquid crystal display device comprising: first register means for storing binary coded numeric information; second register means coupled to said first register means for sequentially storing single digits of the binary coded numeric information stored in said first register means; decoder means coupled to said second register means for converting the binary coded numeric information stored in said second register means into display information; a plurality of first electrodes disposed on a first plate for energization to define a plurality of digits each having a seven bar display format; a corresponding plurality of second electrodes disposed on a second plate which faces said first plate, each of said second electrodes corresponding, respectively, to ones of said first electrodes; a plurality of first driving elements coupled to said decoder means and being operative to energize each of said first electrodes in response to said decoder output; a plurality of second driving elements operative to energize each of said second electrodes; means coupled to said first and second driving elements for alternating the polarity of driving voltage applied between said pluralities of electrodes from said driving elemenets; and pulse generator means coupled to said second driving elements for sequentially selecting at least two electrodes of said second electrode so that only the electrodes corresponding to a particular portion of the display can be energized at a time.
