  • Patent number: 5189406
    Abstract: The display has a video signal receiver and a store with a capacity to hold one picture of the video signal. Row-output devices enable the video information for respective rows of pixels to be taken out from picture store, and each has a bit extractor to separate out one bit of the information for each pixel of the respective row. The resultant signal is passed to pixel drivers which operates on a lattice formed of ferroelectric liquid crystal pixel-elements, which are time-multiplex addressed according to a predetermined sequence, each row being addressed a plurality of times for each picture. In the addressing groups of the rows are set simultaneously, each group consisting of a plurality of rows spaced apart in the addressing sequence such that the rows in a group form a series with adjacent rows having a temporal separation in the addressing sequence exhibiting a geometric progression with the common ratio N being an integer corresponding to 2 or more.
