POLARITY-INVERSION DRIVING METHOD AND DEVICE FOR LIQUID CRYSTAL DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide a liquid crystal display capable of reducing power consumption while keeping image quality when a dot-inversion polarity conversion system is adopted. SOLUTION: A polarity-inversion driving device for the liquid crystal display makes the polarity inversion frequency of a polarity inversion signal higher than the scanning frequency of any horizontal scanning signal of the liquid crystal display and lower than a display frequency between any two adjacent subpixel display points. As devices for that, included are at least a timing controller used to supply the polarity inversion signal and digital image data and a source driver which is electrically connected between the timing controller and liquid crystal display, inputs the polarity inversion signal and digital image data, and can generate and output analog image data having the same polarity inversion frequency with the polarity inversion signal.
