  • Patent number: 4117472
    Abstract: A liquid crystal display device comprising a plurality of liquid crystal elements each having a respective pair of electrodes which are connected in matrix formation for control purposes. Electrodes on one side of the elements are connected in "rows" and electrodes on the other side of the elements are connected in "columns" so that intersections define an element uniquely while reducing the number of control terminals. The "rows" may be formed as a sinuous array crossing and recrossing an elongate array formed by the "columns" so that the display provides a linear progressive illuminable display area. Control signals may be variable in phase, and/or frequency and/or amplitude to effect appropriate selective activation of the elements.
