  • Method and apparatus for driving liquid crystal panel in dot inversion
    Patent number: 6335719
    Abstract: A liquid crystal panel driving apparatus is adaptive for stably keeping a picture quality independently of a picture pattern and improving a picture quality. In the apparatus, the liquid crystal panel arranged with liquid crystal cells is divided into a number of polarity blocks. Each one of the liquid crystal cells included in each block responds to data signals having polarities contrary to data signals applied to the adjacent liquid crystal cells and responds to data signals having polarities contrary to data signals applied to the liquid crystal cells included in the adjacent blocks. The polarities of data signals applied to all the liquid crystal cells in the liquid crystal panel are inverted every frame interval.
