Abstract
A liquid crystal panel driving method and apparatus of cycle inversion system is adapted to stably keep a picture quality independently of a pattern of picture and improves a picture quality. In the apparatus, liquid crystal cells in the liquid crystal panel are divided into a number of polarity blocks. The same polarities of data signals are applied to the liquid crystal cells included in each polarity block, data signals having polarities different from the adjacent polarity blocks to each polarity block. The number of liquid crystal cells included in each of the number of polarity blocks are gradually increased every predetermined number of frame period.
