Abstract
In the disclosed liquid crystal display system, one of two opposing base plates that sandwich an electrooptic liquid crystal between them is divided into separate electrodes or constitutes a homogeneous transparent resistance. A source of power energizes this electrode so as to produce a gradient or stepped voltages between the divisions, and a data voltage is applied to the other electrode so that one section of the sandwiched electrodes can effect light differently than the other sections and thereby display information.
