    Abstract: A liquid crystal or other display device employing a drive and control circuit for activating selected segments of the display with a bidirectional current utilizing integrated circuit technology with a low voltage DC primary power supply to produce and control the bidirectional current. Accordingly, said DC power supply is utilized to operate a multivibrator circuit which at first and second outputs thereof provides rectangular waveforms varying alternately between a first and a second DC level to cause bidirectional current flow through the crystal when a return path is implemented through a bidirectional current conducting switch.

    Abstract: An electronic timepiece such as a wrist watch of the type employing all solid state components including an electronic or a liquid crystal output display for indicating time, utilizes a high efficiency up-converter to enable a small physical and low voltage battery to provide energy for the entire electronic watch assembly by applying said battery voltage to an inductor which conducts current under control of a switching circuit. The control of current through the inductor at specified intervals causes a high voltage pulse train to be developed which is then rectified to provide a higher DC voltage for providing operating potential for the entire electronic assembly of the timepiece. The stability of the voltage output can be enhanced by means of a feedback regulator.

    Abstract: A liquid crystal cell comprises a transparent top support plate having a transparent conductive coating thereon, a bottom support plate smaller than the first support plate and having a reflective conductive coating on one surface thereof and a black coating on its opposite surface is centered with respect to and spaced from the top support plate, a layer of a liquid crystal composition fills the space between the support plates, a metal cover encloses the bottom support plate and liquid crystal layer and is sealed around its periphery to the top support plate by means of a metal frit and solder. The cover is insulated from the top support plate by means of a dielectric insulating layer on the support plate. Spring means are provided which are bonded to the cover and the bottom support plate for holding the bottom support plate in position. A method for assembling the structure is described.
