  • Dynamic polarity control method and polarity control circuit for driving LCD
    Patent number: 8743039
    Abstract: A dynamic polarity control method for driving an LCD is provided. Gray level information is obtained, which indicates gray levels of dots in an image to be displayed. The gray level information is applied to each of a plurality of polarity patterns to obtain a plurality of combined patterns, wherein each of the polarity patterns has an individual polarity distribution. The gray levels of each of the combined patterns are summed up. A final pattern is selected from the plurality of polarity patterns according to the summed results, to drive the LCD for displaying the image.
    Type: Grant
