Video display control system for liquid crystal display or the like
摘要:
A video display system including an energizable video display control element, a power source for generating power and a control portion. The control portion, in turn, comprises a laddic-shaped addressing element, an input wire, and enabling wire and an input addressing wire. The laddic-shaped addressing element has a pair of sidebars and plurality of rungs including an input rung, at least one addressing rung, and an enabling rung, with the sidebars having a lower magnetic reluctance than the rungs. The input wire is magnetically coupled to the input rung for generating an input flux signal in the addressing element, with the input flux signal having a direction representative of the energization state of the video display control element. The enabling wire is magnetically coupled to the enabling rung, the power source and the video display control element for controlling the transfer of power from the power source to the video display control element to control energization of the video display control element. Finally, the input addressing wire magnetically coupled to the addressing rung for selectively controlling coupling of the input flux signal at the input rung to the enabling rung for controlling coupling by the enabling wire.
