Abstract:
An actuation circuit for a liquid crystal display includes a plurality of pixel elements constructed in the form of a matrix of columns and rows and a plurality of column capacitors connected to respective columns of the liquid crystal display that can be charged to store a signal to be displayed. The activation circuit comprises a number of blocks which each comprise a separate group of the columns forming the matrix of pixel elements, a corresponding number of column capacitors, and a plurality of data lines. The individual data lines receive respective signals and are connected to the column capacitors. A switch device is connected to each respective block for successively switching between the number of blocks. The signal to be displayed is fed in parallel through the data lines of the columns of a first block to charge respective column capacitors of the first block and after the charging of the column capacitors in the first block, the input lines are switched by the switch device to the data lines of the columns of the next-following block.
