  • Method for driving source of liquid crystal display
    Patent number: 6577293
    Abstract: There is provided a source driving method in a liquid crystal display, which applies negative and positive video signals to source lines of the liquid crystal display including a first and second plates and a liquid crystal being inserted therebetween, in which each video signal is applied, with its voltage being divided two phases of polarity modulation and gray scale decision. The polarity modulation is accomplished through stepwise charging and discharging.
