Liquid crystal display device and driving method thereof |
摘要 |
An LCD device includes: a liquid crystal panel configured to include liquid crystal cells formed in regions defined by crossing gate lines and data lines; an image analyzer configured to analyze whether or not an image data corresponds to a specific pattern in which a black or white gray-scale data having a large difference between positive and negative data voltages is continuously opposed to the liquid crystal cells of a vertical direction; a polarity control signal modulator configured to respond to a control signal from the image analyzer and modulate a polarity control signal, so as to prevent the black gray-scale data continuously opposed to the liquid crystal cells of the vertical direction from being polarity-inverted; and a data driver configured to apply the data voltages to the data lines on the basis of the modulated polarity control signal applied from the polarity control signal modulator. |
