Liquid crystal display apparatus.

摘要

A liquid crystal display apparatus includes an LCD having a plurality (N) of row electrodes and a plurality (M) of column electrodes which intersect to each other orthogonally. A plurality (n) of row electrodes of the plurality (N) of row electrodes are individually and simultaneously driven by a plurality (n) of row drivers with voltages which are determined according to Walsh functions. A VGA controller which receives a video signal outputs display data of one frame. A plurality (n) of storages individually store the display data of each of n rows which are simultaneously driven. The display data from respective storages are applied to a plurality (m) of calculation circuits. Respective calculation circuits calculate driving voltage values for respective column electrodes in accordance with the Walsh function and the display data so as to apply the same to a plurality (m) of column drivers, respectively. Respective column drivers drive the column electrodes included in each of a plurality (m) column electrode groups with the driving voltage values. <IMAGE>
