Abstract:
1. A driving apparatus for a liquid crystal display, comprising: a liquid crystal display panel having liquid crystal cells at each crossing of a plurality of gate lines and a plurality of data lines; an image signal processor that separates a television image signal from a complex image signal and that converts a polarity of the television image signal in response to a polarity inversion signal; a data driver that applies the television image signal from the image signal processor to the data lines; a gate driver that drives the gate lines in response to a gate control signal; and a timing controller that generates the gate control signal for driving the gate lines during one horizontal period and applies the gate control signal to the gate driver that time-divides the plurality of gate lines to sequentially drive the plurality of gate lines for periods of differing durations during one horizontal period, and that generates the polarity inversion signal inverted for each one horizontal period and applies the generated polarity inversion signal to the image signal processor, wherein the gate control signal includes: a first period generated in a portion of the one horizontal period; a second period, having a period smaller than the first period, generated in the remaining interval of the one horizontal period, the second period following the first period; and a third period having the same period as the one horizontal period, the third period following the second period.
