Method for driving liquid crystal display apparatus
A method is provided for driving an LCD apparatus in which a predetermined image is displayed by applying predetermined column signals to pixels constituting selected rows of an array of pixels arranged in columns and rows. The pixels are divided to form pluralities of groups that each have at least two pixels in either a column direction or a row direction. The column signals associated with each group are provided with a different polarity as to each adjacent group and a group characteristic is changed in different image frames. Alternatively, plural pixels in a column direction can be classified into a plurality of sets with each set including plural frames, and the polarity of the column signals for each of the sets can be changed or groups of pixels can be formed by dividing the pixels in the columns into groups all of which have at least two adjacent pixels in a direction of the columns and further with at least some of the groups having more than two pixels in the column direction and then applying column signals to each adjacent group in the column direction with a different polarity.
