ABSTRACT:
A passive liquid crystal display is enhanced by selectively applying low frequency signals to the columns of electrodes on the substrates sandwiching a liquid crystal, selectively applying high frequency signals to the rows of the electrodes so the first and second signals activate the liquid crystal at selected ones of said rows and columns, and passive storing the energy in capacitances exhibited by said rows at the high frequency with an inductor. The low frequency is below the crossover frequency of the liquid crystal, and the high frequency above the crossover frequency.
