Abstract
In one embodiment of the present invention, when a still image is displayed, applied voltages respectively corresponding to a total of n (n being an integer of not less than 4) types of gradation 0 to (n−1) are outputted to pixels. On the other hand, when a moving image is displayed, an applied voltage corresponding to a predetermined gradation m (1≦m≦(n−2)) is applied to the pixels instead of applied voltages respectively corresponding to gradations of less than the predetermined gradation m.

A method for driving a liquid crystal display apparatus, comprising the steps of:
- when a still image is displayed, outputting applied voltages to pixels, the applied voltages respectively corresponding to a total of n (n being an integer of not less than 4) types of gradation 0 to (n−1);
- and
- when a moving image is displayed, outputting an applied voltage to the pixels instead of applied voltages respectively corresponding to gradations of less than a gradation m (1≦m≦(n−2)), the applied voltage for the moving image being the applied voltage corresponding to the gradation m that is applied for the still image and outputting the applied voltages to the pixels respectively corresponding to gradations of between m and n−1 for the still image.
